Xperia U_6.1.1.B.1.100_AboutSony has released a new firmware version for the Xperia U (ST25) with build number 6.1.1.B.1.100. The Android 4.0.4 Ice Cream Sandwich firmware keeps the 3.0.8 kernel. We are not aware of any tangible changes over the previous version (6.1.1.B.1.89), so it is likely to offer minor bug fixes. If you have downloaded it let us know what differences you have noticed.

  • Rpk

    I don’t think so.Sony is late and always will be.

  • Rahul Bihola

    Are you sure? Ion will get jelly bean in next 1 hour?

  • knaqvi

    Not here in Pakistan. :/

  • deol275

    I agree with you man…this is disgusting.

  • Prateek Bhanushali

    ohh my, sony still working on ICS.
    please release it for Xsola, my brothers phone keep crashing all the tymm…

  • Prabha

    Well.. I did not get any updates since
    “6.1.1.B.1.10” its 10 not 100


    Oh c’mon Sony… None of your firmware is updated on any site.
    U can check…. its still 6.1.1.B.1.10

    Now Plzz can anbody tell me how to install this firmware..
    please plzz plzzzzz

    ‘coz my xperia u has gone so slow … Its better to have 2.3.7 rather than 4.04

    Seriously guyzz do something

  • sfordesign

    that’s typical sony. their stupid staff don’t know shit, and their sites only update for the newest devices, for a very short while.

  • Uchiha Dare Nial

    Sony,I want JB (Jellybean) for my ion,not JB (Justin Bieber) in real world….but if you can get rid JB (justin bieber) from this world,I would be happy enough lol

  • Amimanot

    Dude, chill… remember that the xperia 2011 line owners never got anything above ics. Even the ics update is buggy and you never saw us complaining? So chill…

  • Ben Ling

    Sony when will you release the .89 update for sola???
    Why only Xperia U get the update???
    I’m not satisfied. :(

  • James G

    whiners . . seriously. . .

  • jag

    Where is my ics for xperia play?? Haha! I did not even whine over this fact. i still love my xperia play even it is in gb

  • neil

    still i didn’t receive an update PC stock firmware .10 .. Philippines.

  • Utsav Shah

    This is something i feared of and looks like it is turning out to be reality. :(


    no dude .. its just on this site only that the firmwares are showing…

    Most of us (xperia U users) didn’t even get any of the updates….since 6.1.1.B.1.10

    Sony is not aware of proper marketing of their products….

    No offence but we all know why samsung sets are well known by everyone.

    Sony cannot understand.

    and u know what out of 3 novathor sets… only P got proper updates…
    Neither sola got nor U….. its just in their heads :P

  • kedar

    Sony please release jelly bean for sola and u.
    grand request.

  • Tobber

    I don’t get it. Why are so many crying about this update not beeing available in their region?
    Just head over to xda-developers, download the FTF and flash it via flashtool…
    Or better yet, install CM9.0. It’s the only way you get a Xperia U with massive lags!

  • Faris

    Same as me.. I am from Malaysia too.. We have miss a lot of update :( Really Disappointed..

  • Cristi13

    Exactly, because you guys didn’t complain about their policy, they didn’t change. Actually there were a some people “whinning” about the 2011 lineup

  • KubsiJack

    14 hours after =))

  • ashik

    is it smooth or laggy?

    What does this have to do with the Xperia U update?

    I wanted to know the changelog and I thought it might’ve been in the comments.

    I guess not.

  • westberg

    Update will come in 1 hour from now…to eternity.

    Yeah, worthless words of deceitful men.

  • Umarabdaziz

    just go to xda, install JB.. I’ve tested few version and it’s okay.. just the matter of few bugs such the front camera and LED bar.. overal, better than ICS I think

  • Ben Lim

    You can always flash the firmware by using flashtool.

  • Uchiha Dare Nial

    Well you are at the wrong comment fella lol

  • checo79

    another off topic ion user?

  • SeeJee

  • Snyper0012

    If you guys are so pissed with Sony not releasing a Jellybean update for ion, then your only solution is to: Root Simple as that. If you want it that badly you shouldnt be worrying about the warranty whatsoever, and you should be willing enough to learn to root your phone. It really isn’t that complicated of a process.


    Okk i got 6.1.1.B.1.100

    But what are the major differences…..

    My xperia U is still slow as before :P :P

    So whats the use of getting a new firmware ???????

  • Dinesh

    I’m stil in gingerbread bcoz peoples said ICS have huge Lag in xperia u…Can i update my software? Please reply me..

  • josesl16

    I don’t have an U, but if you are still in GB, I think you’re missing a lot of new things. Personally, even if there are some bugs/lags, I will still update it anyway. Gotta step back a little to jump far ahead, eh?

  • Jamolan

    I love this update. My phone is now faster and consumes less data

  • tere apna baap

    madharchod ,xperia u ka jellybean update nakalne se teri maa ni chud jayegi

  • Avanox

    Please sony! Release Jellybean for Xperia U !! ICS totally sucks! Mine is android 2.3 again because ICS just is realy bad & slow on xperia U!

  • cvc

  • Raj

    I cant find even 6.1.1.B.1.89 update on the official site and your saying 6.1.1.B.1.100 ….. come onn…..

  • boby

    Can any one please help me. Some times i see glitches in my phone. Xperia u. Its not even 6 months old.

  • G.viswanadh

    ya.recently i updated my xperia u.its working.but i need jelley bean for my xperia u…………so can any one tell whether xperia u is getting JB or not

  • Chirag

    But my phone is running on .54 check for an update
    if u have unlocked bootloader then relock it with the help of flashtool!!

  • Chirag

    kich ur ass of mister cauz this news cannot do anything for u about jelly bean need an unofficial one surf the xda forum

  • Chirag

    no it is not brother even i m really worried about this beacuse when i bought my phone it was of rs16458 and when i try to sell it, it goes only for rs 10000

  • Chirag

    Dinesh xperia u is not that much slow on ics but sometimes if u r using too many things at a time it will obviously show some lags dont worry about that becauz xperia u can handle this pressure very easily and think of the update of ics i was really excited when i got to know my phone is capable of going to ics and it showed me a positive response after updating so dnt worry and jst update!!

  • JellyBreaker

    Please stop whining about the jellybean update on phones like xperia U, Sola etc. They ‘re fine phones but not made for Jellybean (actually since the phones came first it’s the other way round. JB is not made for such phones).
    Have a look on your own before start shouting. The web is full of posts from ‘lucky’ owners of phones like Samsung galaxy Ace 2 (which has more ram than U) who got the upgrade and wish to return back to gingerbread. They even codemn Samsung for releasing such an dreadful firmware (just like you do with Sony for NOT releasing JB).
    The same with xperia Go. They got the ”precioussss’ JB and after a couple of days regreted and and try to go back to GB.
    Jellybean needs 1gb ram to run properly (I mean 4-5 apps running, fluid and no lags etc).
    So stay with GB or buy a new expensive phone to have JB

  • Pranav Kashyap

    but i still have 6.1.1.B.1.10 firmware and no update is shown on PC companion
    also sony plz release JB update fr xperia u as it is much awaited

  • Anmol

  • abc

  • ho ss

  • Leod Onadi

    Please tell me how did you turn ICS to android 2.3

  • ceki

    Don’t update bro. Trust me.

  • Houssem Boussaid

    Hello , I heard that The Sony Xperia U runs so slow on 4.0.4 is that true & what i supposeto do to make him run normally or faster

  • future xperia z1 user
