Install Xperia Marshmallow using Flashtool and XperiFirm [Guide]

in Android, Featured Content, Firmware, Tips & Tricks

MM Xperia Guide_12It is that time of the year again, where we have a major Android release and people want to update as soon as possible. We have received numerous requests from Xperia Z3+ and Z5 owners asking how they can manually update to Android 6.0 Marshmallow, using third-party utilities Flashtool and XperiFirm.

We’ve covered the process many times before, the last time being a year ago when Android 5.0 Lollipop made an appearance. Therefore, it seems like a natural time to revisit the guide. It is worth noting that whilst the tutorial below shows how to install Android 6.0 Marshmallow, the procedure can be used to flash ANY firmware build for ANY Sony Xperia device. The steps are also the same to debrand any Sony Xperia device that is currently on carrier-specific software.

Installing Xperia Marshmallow using Flashtool and XperiFirm [TUTORIAL]

Disclaimer: Please read the following instructions thoroughly before attempting to flash your phone. Xperia Blog absolves itself from any responsibility should something go wrong. Please proceed with caution and at your own risk.

Note: You will not void the warranty of your Sony Xperia device by flashing new firmware using this guide. In addition, you do NOT need to unlock your bootloader nor do you need root to flash your handset.

It is recommended that you create a backup of your existing regional/carrier firmware just in case you need to send your device back for repair. The instructions below can be used to create any firmware file, so use these to create a backup with the relevant firmware build.

Part 1: Preparation

One of the primary reasons people encounter problems in flashing their device is due to not installing the correct drivers on their computer. Please ensure that drivers for your Sony Xperia device and Flashtool software are correctly installed on your PC before attempting to install new software.

Note: This guide is written for Windows users in mind only.

1) Install drivers for your Sony Xperia

You need to ensure that your PC has all of the necessary drivers installed for your Sony Xperia device. The best way to do this is to install Sony PC Companion.

Make sure you connect your Xperia to the PC before starting the process to download the necessary USB and ADB drivers. The best way to do this is to power off your Sony Xperia and then connect to your PC whilst holding the volume down button.

2) Install Flashtool

Download and install Flashtool from the official website here. This guide is based on using Flashtool version

Install Flashtool drivers from the following location: ‘C:\Flashtool\drivers’. Tick the “Flashmode Drivers” and “Fastboot Drivers” to install.

MM Xperia Guide_Flashtool Drivers

Note: To install the Flashtool drivers for Windows 8/8.1/10, please follow the steps below.

A) Press the Windows key + R together and in the ‘Run’ box type: shutdown.exe /r /o /f /t 00
– Now make the following selections to boot into the Start Up Setting Screen: Troubleshoot > Advanced options > Start Up Settings > Restart
– Then, when the machine restarts, select number 7 i.e. “Disable driver signature enforcement”. Your machine will start with Driver signing enforcement disabled until the next reboot.

B) Now you can install the Flashtool drivers.
– Windows will warn that the driver is not signed and will require you to confirm the installation.
– Once the installation is complete, reboot the machine

3) Enable “USB debugging” and “Unknown sources” on your Sony Xperia device

‘USB debugging’: Settings > Developer options

‘Unknown sources’: Settings > Security

Part 2: Create your FTF firmware file

You will need a FTF firmware file to install new software onto your device. The following section explains how to create your own FTF firmware file, however if you have downloaded a FTF file from the Firmware Resource section of our website or elsewhere, you can skip this step and proceed to part 3.

To create your FTF firmware file, you will first need to launch Flashtool and then click on the XperiFirm icon as highlighted below.

MM Xperia Guide_1_Red

You should now see the XperiFirm software launch into a new window. Navigate to your handset on the left pane. You can then choose the firmware for your region/carrier in the middle pane. The pane on the right side will show you which firmware is available for that region. Click on it to download the file.

Important: Only download firmware for your model and variant number. For example, if you own an Xperia Z5 (E6653), only browse and download the firmware builds listed under E6653.

MM Xperia Guide_2

Once clicked, you are asked to confirm whether you want to download the firmware. Ensure that “Unpack automatically” is ticked and then click “Download” to proceed.

MM Xperia Guide_3

Once complete, you will see the following pop message “Unpacked Successfully!” Click OK.


The same “Unpacked successfully!” message will appear on the download dialog. Click “Close” to proceed to the next step.

MM Xperia Guide_4

You will now revert back to Flashtool, which will start creating your FTF firmware file.

MM Xperia Guide_5

Once you see “Torrent file creation finished” then your FTF firmware file has been successfully created.

MM Xperia Guide_6_red

To ensure the FTF firmware file has been created, navigate to the following location on your PC: “C:\Users\[Your PC Name]\.flashTool\firmwares”

MM Xperia Guide_7

Part 3: Flash your FTF firmware file

This section details the steps needed in order to flash new firmware onto your Sony Xperia device.

First of all, open Flashtool and then click on the lightning bolt in the top left of Flashtool as highlighted below.

MM Xperia Guide_8_Red

Select “Flashmode” and click “OK”.

MM Xperia Guide_9

You should already be in the source folder where the FTF firmware files are located. If not, navigate to: “C:\Users\[Your PC Name]\.flashTool\firmwares”

Select the firmware build version that you want to flash from the “Firmware” pane. Ensure the device variant is the same as the model number of your Sony Xperia device.

If you want to retain your apps, data and media (photos, videos, music), then ensure that the “USERDATA” option within the “Wipe” pane is unticked. However, we recommend that when upgrading a major new Android version, a clean install is the way to go. In this case, tick all options under the “Wipe” pane. This will wipe all of your data though including your photos and videos, so please ensure you have these backed up elsewhere.

MM Xperia Guide_10_b

IMPORTANT – For FlashTool and older: If you skipped Part 2 of the guide as you already had your own FTF firmware file, then you may see the following ‘SIMLOCK’ option ticked under the “MiscTA Exclude” pane. DO NOT untick SIMLOCK as it could lead to problems with the network lock on your device.

MM Xperia Guide_Simlock_2

IMPORTANT – For FlashTool versions to The developer has changed the meaning of the tick box in newer versions of Flashtool, which means ticking the box includes “SIMLOCK”. Either way, you want to ensure you are NOT including SIMLOCK when flashing firmware. So to be clear, when presented with the “SIMLOCK” option below, you must NOT tick the box.

Flashtool Simlock

NOTE – For FlashTool onwards: The developer has disabled “SIMLOCK”, which means you no longer have to worry about accidentally including it in your firmware flashing. The option is only enabled by entering ‘Pro’ mode. Unless you know what you are doing, then stay well away from Pro mode.

Click “Flash”. Flashtool will then indicate that it is “preparing files for flashing”.

MM Xperia Guide_11_red

You may have to wait around 60 seconds for the pop-up below to appear. Once it does, you should now connect your Sony Xperia device. Make sure the device is powered off and then hold the ‘volume down’ button whilst connecting the USB cable. Once the pop-up disappears and flashing has started, you can let go of the ‘volume down’ button.

MM Xperia Guide_12

Flashtool will then start flashing your Xperia device.

MM Xperia Guide_13

Once you see “Flashing finished” as indicated below, your Sony Xperia has been successfully flashed.

MM Xperia Guide_14_red

Congratulations you have just installed Android Marshmallow! Now disconnect your Xperia device and power on the handset. Don’t worry if it takes a while for the handset to boot, this is to be expected.

To confirm that you have upgraded the phone software, click on ‘Settings > About phone’, which will reveal your new Android version and firmware build number.

Xperia Marshmallow Guide_1

If you would also like to confirm the region firmware that you have downloaded, you will need to access the service menu option. To do this, open the dialler and enter the following: *#*#7378423#*#*

Then click ‘Service info > Software info’. The CDF is an eight digit number under the “Customization Version” that should tie in with the firmware you downloaded from XperiFirm. For example, you will notice below that the CDF (software customisation version) of 1298-7362 matches the same firmware that we downloaded in the XperiFirm screenshots above.

  • AsadMulla


  • William Tavares

    The whole process is pretty easy!
    Any one with the minimum knowledge in Android flashing will do it in the first try.

  • mugglearchitect

    wait, in marshmallow, they actually set the notifs bar color black again? btw thanks for this!

  • Camilo Uribe

    Can someone please share with me the FTF from marshmallow-beta for my Z2?

  • Bashar Shehab

    When I saw the title I was like ” WTF! they got the Xperia Beta FTF file!!!!! ” and then I realized this…. Oh XB why you do dis? :’3

  • Sadman Khan

    Yes. Black by default. But if you change theme, it will change accordingly

  • Samuel

    Impossible to build an ftf file from an OTA update. If possible, it will be like a custom ROM (.zip) for unlocked bootloader. We are all waiting!

  • twm

    Common concerns from the citizens:
    1. Why did we install Fastboot drivers if we don’t ever use those drivers?
    2. How do people view the CDF with WiFi only Xperia tablets?
    3. What are the best CDF-s that are always among the first to get the updates?
    4. How do I exit from part 1.1?

  • Filip Gonda

    Do I need root to flash?

  • Sharp Edge

    Nope. In fact, if the FTF has root added, you can use Flashtool as the quick and easy way to get root.

  • Sharp Edge

    Betas. I figured this out on my own. Is it really that difficult to make a cup of coffee and google for 10 minutes?
    As a side note, I recommend everyone to do a clean install unless you want your device to be plagued with bluetooth, fingerprint and radio-activity bugs. It takes an extra hour or two to set up your device to the way it was but you have the peace of mind that there’s a nice clean installation of the OS laying on your phone. Any bugs after that can be blamed on the system rather than your own laziness.

  • XperiaBlog

    In answer to your questions:
    1) You are right, the Fastboot drivers are not necessary to flash firmware, but as an initial setup in installing Flashtool, there’s no reason not to do it just in case you might need it down the road i.e. if unlocking the bootloader.
    2) This guide still works:
    3) This will vary by variant, but we find the Nordic, Russia, Hong Kong and Singapore regions typically always receive updates quite quickly.
    4) No harm in just puling the cable once the drivers have been successfully installed.

  • XperiaBlog

    We would agree. Just recently we flashed Marshmallow to another device without doing a clean install. However, we were then plagued with an issue with the Google Play Store force closing. In the end, a clean install was required to fix the issue, which highlights one of the many potential issues you may get when flashing a new Android version without wiping clean.

  • Unknown

    We hope to see Xperia Blog with Material Design

    This site with very nice design

    and also SamMobile with nice design

  • Filip Gonda

    I dont have z5 I got only m4 aqua but its good phone

  • jez

    Can i install marshmallow on my ZR by following these steps? Please advise.

  • Bashar Shehab


  • Michael Hannam

    Does the phone need to be fully charged before you begin? Just thinking if the phone dies while flashing it, that may corrupt the process

  • turco320

    after installing this come the next updates OTA normally?

  • Filip Gonda

    And i got one little question :D must be phone fully chaged when iam flashing?

  • Sharp Edge

    The more battery it has, the better. It’s technically charging during the flashing but it should have enough power for it to fully boot afterwards. I would say that 50% would be more than enough juice to do the whole procedure.

  • GreekBoy

    My Z5 Compact is version E5823 Vodafone Germany (R6C). I live in Greece and I wonder which is the best way to debrand it. Should I use the “Customized GR” version? Generally, the “Customized” national versions are the ones to go for debranding?

  • SM

    Can I flash any xperia device or only those which support marshmallow officially?

  • Igor Eisberg

    Yes. This doesn’t affect OTA updates.

  • Igor Eisberg

    Yes. Customized are generic retail firmware that were ‘customized’ for a specific country/region.

  • Igor Eisberg

    Don’t try this if you’re less than 60% on battery level.

  • Michael Hannam

    Alright cheers
    My z3+ is on Vodafone network but voda doesn’t have Android 6 ATM on ftf. Can I use a custom USA ftf or do I have to use my country and network while choosing ftf

  • Igor Eisberg

    I guess you have model E6553. You can generally use any firmware under the E6553 list. I live in Israel and use the Customized US firmware. The significant difference between these regional firmware is the APN-List file. It has APN entries of mobile virtual network operators (including virtual operators) in your country. What it basically means is if you don’t have your regional firmware (and an APN list), and you’re on a MVNO (those virtual operators that “piggyback” on the major carrier’s networks), you’ll see the name of the actual major carrier instead of the virtual one.

  • Michael Hannam

    So I shouldn’t have any problems with using my phone with voda network? As its locked to the Vodafone network I belive

  • GreekBoy

    Thanks bro

  • Eduardo Otero

    Only those which support Marshmallow officially (Z3+, Z4 and Z5 series)

  • Igor Eisberg

    I doubt that it’s “locked” to Vodafone, but Vodafone is an actual network carrier (not a virtual one) so you won’t have any APN-related issues.

  • Jecht_Sin

    The issues with Google play force closing are usually fixed uninstalling the Google play and Google play services updates and download the updates again. Cleaning their data on top of that also helps.

  • Michael Hannam

    when I visited Vienna when I used a 3 network sim the phone didn’t register that there was a sim in the phone. I’m guessing it would still pick up the voda network if it searches the local networks.

  • turco320

    btw, works great this guide, thanks xperiablog (Z5 E6603)

  • Igor Eisberg

    How it works is beyond me, you’re welcome to experiment…

  • fried_egg

    I don’t want to lose EE firmware exclusives like 4G+ (75Mpbs) and wifi calling… so i will wait.. although i hope they are not going to be back to the bad old days of weeks later for the update… the last few have been within a week of the unbranded ones…

  • Eduardo Otero

    No, only Z3+, Z4 and Z5 series.

  • Sandeep Kumar

    thanks :)

  • Tadija Djurovic

    Flashtool don’t show the option SIMLOCK ( MiscTA Exclude) Flashtool detect locked devices, and after that show this option? My Sony Xperia Z5 is purchased through an network operator, device is simfree, and use generic firmware. Thanks

  • Cpt.Pancake

    How long does this whole process take? My phone (Z5) has been hooked up for hours now. and nothing happens. I created the FTF file, powered down, started the flashing process and hooked it up again as described.
    Flashtool starts flashing
    – Processing loader
    -checking header
    – Flashing Data
    – Loader: S1_Root……Bootloader Status ROOTABLE
    -Max Packet Size set to 4096K

    and then nothing….
    any ideas?

    Do not use Flashtool on Xperia M5/C5 Ultra, the latest version currently available ( will either fail while writing TA unit or in some situations progress a little further before failing too, leaving your Xperia M5/C5 Ultra bricked.

  • XperiaBlog

    We agree, usually that works in most cases. However, it didn’t for this particular issue. Even rolling back to the factory installed version made no difference.

  • XperiaBlog

    That is natural and depends on how the FTF was created. If it doesn’t show, there is no need to worry about it!

  • XperiaBlog

    So you see the green bar to indicate it is flashing but then it just stops and no longer progresses? The whole process should take no longer than 30 minutes and that is being generous with timing.

  • Cpt.Pancake

    Actually the green bar went full in a matter of seconds. But I tried it at home on a different Computer. Including DL it took 20 minutes…

    I noticed, when Flashtool automatically create ftf file, option with SIMLOCK not included. When I manually create ftf file, the SIMLOCK option included. I am flashed android 6.0 marshmallow with first method, when flashtool automaticaly created ftf file.. Thank you very much Xperia Blog team.

  • I’m looking for an ftf file of 23.4.B.0.319 for my Xperia Z2 tablet SGP561. This particular model is Verizon branded and I was able to complete the above steps to install 23.1.D.0.509, which is linked in the article, but would like to get the newer build that’s available.

    I would do this as an OTA upgrade but I moved to Canada and no longer have access to Verizon’s service to do the upgrade. The carrier locking on this is extremely frustrating for people who no longer have access to the service (and they claim there’s no unlock code).

    Any assistance finding an ftf file of 23.4.B.0.319 would be greatly appreciated.

  • Adrian G.

    Hi there, it’s my first attempt to manually flash stock firmware for my domestic market for Marshmallow 6.0 on Z3 Compact. But I have one significant question, how long does the flashing process usually take for a normal period of time. I know that hardware also determines the speed of the installation process, but is it longer than the installation of Windows ? That bothers me, still over half of the flashing process right now and the bar indicator remains the same, it’s been more than 20 minutes or so.

  • Harry Ix

    What a mess!
    I’ve tried, but I left it in step 1. I have Win10, and had a restart, not as was descripted here.
    I won’t take the risk
    Better what Blackberry did and does with the “autoloaders”.

  • Harry Ix

    Finally I went to my work PC, where I have a partition with Windows 7 and things has gone better. I followed the steps paying attention to every minor detail.
    Now I have the Marshmallow in my compact tablet sgp611, with no problems so far.
    Mrshmlw runs smooth and no bugs till now, 3 hours later. ( I also have M in my Samsung S6 with the Samsung “dress”).
    I still think that it would be nice trying to make easier “autoloaders”, as BBerry. But in spite of that, this was a very good job. Thank you.

    Now when I connect to flash (Holding Volume Down) It boots into safe mode, still, but Flashtools says debugging is off. It clearly isn’t cause I have it enabled and there’s a notification that says “Click to turn off USB debugging”. Why isn’t it connecting properly?

    The old way of creating ftf file is let flashtool decrypt the file and then selecting all the folders (including boot folder) to create the file.

    The new 5.0 xperifrim will automatically unzip the files. how does one create a new ftf with the new xperifirm?

    when i tried creating a new ftf file, i selected the folder where the files were unzipped but i noticed that the boot folder is nowhere to be seen.(highlighted in yellow)

    the last time i included this manually in flashtool, i bricked my tablet.

    am i missing something?

  • 4ndr35

    Thanks so much, but when I plug the phone in Flashmode, im getting this message on Flashtool: ERROR – Can’t read a byte value. I have xperia m5 E5606 and im flashing Xperia M5 E5606 30.2.A.0.100 FTF

  • Edward Campos

    Hi all, I perform all the steps in my sony xperia c4 e5306, and now my smarthphone don’t turn on. I tried several ways (with volumen up and down keys, power buttons) and there are no way to turn on my phone. Also I tried to repair my cellphone with sony companion and in the last step after press the volumen key down and power buttons nothing happens. Only a red light is showed when I connect my phone to my pc. Please could someone help me? Thks in advance

  • Yasser Valcarcel

    I had an issue with the last software upgrade, I try to download it twice but I was connected to very slow WiFi connections and both times the download failed. Afterwards, both the phone and the Xperia Companion told me I had the latest available update even if I knew it wasn’t. Luckily, I was able to install it using the FlashTool. You guys rock!!!!

  • Quest

    After using Xperifirm, Flashtool pops up with “A FSC script is found : default.fsc. Do you want to add it ?” Should I click Yes or No?

  • Michael

    Hey man.. Did sony replace your phone’s mother board or they just did something with the ta partition?
    Because i have exactly the same problem :(

  • Michael

    Hey Zsolt.. I don’t have a ta backup :(

  • Same problem here on a XA Ultra (F3213), bought it recently, flashed it with US ROM and now it doesn’t turn on, only sign of life is that red led. HELP PLEASE!

  • Try updating your Flashtool and adjusting max. buffer size to 512. It should work!

  • Edward Campos

    Thanks goodness my cellphone was in guarantee, I went to my current operator and told them that my cellphone suddenly turned off and now dont turn on. Happily they believe me and I could change my cellphone for a new one.

    Excuse me, I don’t find any usable European firmware for Xperia M5 E5653 …
    Is installing “M5 E5603” version dangerous ? or I can take the risk ?

    Hi, my device has been soft bricked. Can I follow this tutorial to get it to working conditions again? I dont know wt my battery percentage since I can see nothing on my phone

  • No se supone que Flashtool brickea los C4? eso dice la pagina de Flashtool…

  • Eduardo Mejía

    Now the version I have is, they are compatible, but I still doubt to flash my M5…could you please help me step by step?

  • Eduardo Mejía

    I get this message, anyone has this problem? what should I do? I was reading comments from other webpages and they claim having problems and bricked the M5 while flashing Android (do not know what version) and the issue was not syncing the flashtool device database…how do I update the database? It this message in the screenshot a problem?

  • Pedroam

    The explaination for “A FSC script is found : default.fsc. Do you want to add it ?” is missing…

  • Eduardo Mejía

    Select “YES”

  • Reggie Thompson

    Help, After clicking flash mode, the firmware selector window pops up but all panels are empty. Source folder points to the correct location but no FTF file appears. The file is in the correct folder. Ver.

  • Chuckjkm

    I recently bought my Sony xperia m4 aqua dual about 5 months ago ,and starting a week ago i woke up to discover it has no working network services.At first i thought that the local network had a problem so i did a restart while selecting GSM as the mobile network.To my surprise it booted up saying no network,emergency calls only.Changed the lines and inserted into another phone and they were working well.Later i went at the “about phone settings”and selected the sim status and i saw
    Here is what it says when i go to ‘Sim status’:
    Network: no service
    Signal strength: 0
    Mobile network type: unknown
    Service state: out of service
    Roaming: not roaming
    Mobile network state: disconnected
    My phone number: unknown
    IMEI: ******************
    IMEI SV: ***
    Checked with the local network providers and their network was okay except that my phone had a problem and seem not to know what could have happened.I also inserted other sim cards but still the no service message came out.I later repaired my phone using Sony companion but nothing improved.Im now starting to believe my phone has been network blocked because neither the service providers could fix my problem and here i am just left with a phone that now works as a WiFi receiver.

    This also another info it shows now


    [x]Network 0

    [Network subset 0

    [x] Service provider 0

    [x] corporate 0

    [x] SIM 0


    [x]Network 0

    [Network subset 0

    [x] Service provider 0

    [x] corporate 0

    [x] SIM 0

    It is not getting any network services.So i am in need of expertise to solve this

  • merolrockstar

    Haha Me paso exactamente lo mismo, Flashtool y no prendio mas, al parevcr debe ser algo del modelo. Igual fui a reclamar garantia con Telcel y sin problema. Pero es bastante raro

  • Nor Arshad

    I did this and now the phone is in bootloop, when i start the phone it goes gray until it restart itself and it keeps going like that. any help? z5

  • Andrea

    Hi to all, if I want just debrand my Z5, which already has MM, it’s necessary to wipe all data? Can I flash a generic version of MM firmware without wipe?

  • therobyouknow

    Thank you, I found it to work, here are some bits of info that may help.

    I successfully flashed this phone with what I think is the “Stock” Android 6.0.1 from Sony into order to get rid of/debrand the O2 branded version on the phone.

    Thank you very much. In return for your useful advice and tools I’d like to share some minor differences not documented in the steps that might help other users and give them peace of mind.

    I found my flashing to work fine using a Windows 10 Pro 32 bit machine to which the Sony Xperia Z3 Compact phone was attached via USB 2.0. Flashtool version

    I didn’t need to do the volume down then plug in to get the drivers to install for USB drivers install as beforehand I installed Sony’s Companion software first as required. With that installed,I am assuming it meant that I didn’t need these extra steps. But note that when it came to flashing later, I did need to follow the steps to hold volume down button then plug in.

    I note that with my version of the tools, the unpack option was not there but it unpacked automatically as required.

    You may also get a message: “A FSC script is found : default.fsc. Do you want to add it ?” – I got something like this, and the advice below in previous comment is to click yes, which is what I did.

    After clicking flash on the firmware selector dialog as described, I got a message something like those data not in the fsc as a dialog pop up, my response was to click ‘yes’.

    The progress bar for the flashing seemed to stop for a while just before the end (it seemed stuck/frozen/hanged) but I waited and it eventually finished, much to my relief.

    Hope this helps others.

  • Tejas Mhade

    Thank You so much…

  • Balraj Singh

    I have Xperia Z5 ( E6683 ) .
    I’ve got multiple .ta files. Which .ta files should I exclude before building the firmware?

  • Abubakar Shekau

    Exclude every .ta file and delete fwinfo and build it, thats it. Enjoy

  • Abubakar Shekau

    Just download germany customised firmware, exclude every .ta file and delete fwinfo, build rom and flash that’s it

  • Abubakar Shekau

    You have to wipe if you want to debrand. Without wiping phone will work, but it will be slow as shit.

  • Abubakar Shekau

    You have to exclude every .ta file and delete fwinfo, otherwise it will bootloop

    To flash stock Xperia Z2 D6502 6.0.1 firmware, do i need to create FTF deleting fwinfo.xml and without any of .TA files? phone is in Locked Bootloader and everything stock. i already downloaded the firmware using xperifirm and flashtool is

    Is there a solution to this problem?

    Thank you, but Im having trouble flashing. It stuck on Closing TA partition, and the loading bar does not move anymore.

  • Gabrielle Person

    Unfortunately, I can’t get past Step 2. I get ERROR-null when I try to create a bundle. I do really want to back up my firmware before I flash 7.0 on it (downgrading from 7.1.1). Any help would be appreciated. (Phone made in UK so I tried the Customized options there.–I’m in the US, bought phone on eBay–Then I found the service menu and my Customized version matched the Hong Kong Customized HK firmware for 7.1.1. But that had the same error: Error-null.

    I’m stuck.

  • Gabrielle Person

    Same thing here. I’ve tried 3 different ones.

  • Gabrielle Person

    I would love to know this, too! I have that tablet and it’s branded to Verizon. I don’t use Verizon. If I can solve this with my Z5 phone I may try with my Z2 tablet. But I don’t want to screw it up. It’s working fine (except it can’t charge on magnetic port). The Z5 is having issues so I’m willing to try it there first to maybe fix them.

  • Mario

    Hello Saddamjit, did I heard correct, this helps you do downgrade from version 7 to version 6? and also does this voids the warranty?

  • Saddamjit Singh

    yes u heard correct

  • Mifta

    NOTE: If your list of files includes “fwinfo.xml” as highlighted below then manually delete it before continuing to the FlashTool steps. You MUST delete this file otherwise your FTF firmware file will corrupt. more:
