Minor updates certified for T-Mobile Xperia Z3 and Z1s – Stagefright patch on the way?

by XB on 10th September 2015

in Firmware, Xperia Z1, Xperia Z3 series

T-Mobile Xperia Z1s_14.5.B.0.247Two new firmware updates have been certified by the PTCRB for T-Mobile US handsets. The Xperia Z3 (D6616) has seen build number 23.1.C.0.399 certified (versus 23.1.C.0.385 currently), whilst the Xperia Z1s (C6916) has seen build number 14.5.B.0.247 certified (versus 14.5.B.0.236 currently).

Given the small change in build number, we don’t expect this to be the Android 5.1.1 firmware update unfortunately. However, we would expect this to fix the Stagefright exploit amongst other bug fixes. We’ll keep you posted once it starts to roll.

    Hi when android 5.1.1 for z ultra will released without bug?

  • Damien

    Believe it or not… No one knows anything about Z Ultra. No date, no update, no comments, at least for now, if I’m not mistaken, Z Ultra is the last one of the Z series who hasn’t received the update yet.

  • Gerges Saber

    what about Z1 (C6903) ?! any news?!!

  • Jaspreet Brar

    also z1 and z1 compact as well as z3+ too. Our bad.

  • amit kumar anand

    Any news about z ultra. Fuck of sony because he says that z1 z ultra be the first to get update 5.1 after z2 z3. But old z series and t2 ultra get 5.1.1 update first.

  • amit kumar anand

    U r right. Z1 and z ultra couldn’t received update

  • Hamid Jafari

    I believe u bro
    I just don’t understand why Z Ultra is the Last????

    Z3v is still on KitKat, and Verizon isn’t going to release any new updates as the dates are TBD. Z4v is on hold (possibly cancelled) now as my Verizon rep said that it has fallen behind on production. One good thing though is that Verizon is now trying to get their hands on the Z5 in the States before the end of this year.

    I hope to get the Premium in my hands.

    When will my z1s get the 5.1.1 update? T-Mobile better not funk this up.

  • Abhi

    T-Mobile has a seperate AOSP branch for devices apparently where it has commits with WiFi calling etc. which Sony and other OEMs have to incorporate for updates. Probably no 5.1.1 for us I think, only the stage-fright fix.

  • Wolf0491

    Damn verizon sounds awful. I usually don’t mind a bit of a delay but on 4.4 lol? The Z3 should be at 5.1.

    Can you flash the regular z3 firmware on the Verizon version or is it to different?

  • WilliamTell13

    We got 5.0.2, I don’t think it would be that hard for Sony to put 5.1.1 on the Z1s.

  • Maxnoob

    I got the 5.1.1 update, but why?

  • sammyl

    Is there a Sony Stagefright patch for C5 ultra? Just got this phone the other day!
