  1. One step that may be missing, if you can’t get the phone into FlashMode then you may need to install drivers for it. These can be found in a folder under the flashtool directory;

    C:\Flashtool\drivers\Flashtool-drivers.exe

      • hi anurag! i just finished flashing to downgrade my z1c from updated 14.4.a.0.157 build number to kernel 14.4.a.108.

        but after the procedure my z1c suddenly appears to be blank., i cant see anything from it., but my pc still recognizes it.

        what can i do? please help! thank you very much. any reply will be very much appreciated

  2. Cool.

    Only reason I mention it is that I didn’t have these drivers instaled (not sure why else you would have them or even where t oget them other than this tool?).

    Windows just gave me “driver failed to install’ errors when I tried to enter flashmode or fastboot and I spent ages trying to figure out what the problem was.

    • well as far as i see, in version 0.9.12.1 of flashtool, Xperia Z1 and Z Ultra drivers are already added and when user first connected his phone to PC, Z1 drivers were automatically installed.

      No issues of drivers ever here :)

    • i don’t have the issue as i got may yellow tint Xperia Z1 replaced from Sony. Sony says the display is brighter in this update.

      But let me tell you my true words :- i don’t find any change rather i think display is even more dim in this new update and it still has yellow hue tint on screen as told to me by many users.

      Camera has improved a lot :)

    • i have just updated the links for indian version.

      Well on journalist version, NFC bug was there. Some preloaded apps difference nothing more, same kernel, same firmware.
      It’s just the after flashing a certain region firmware then you will get future updates as per it only.

    • you didn’t get update yet. Almost every Indian user which were in my circle got the update. Still if you haven’t got it yet. You can download the Indian version ftf, it’s live now :)

  3. Generic India update is not getting downloaded. only 1 kb md5 file downloads every time.
    File property also shows its size only 172 Bytes.
    Please provide another link.

    has it been removed from skydrive?

  4. Hi, the phone can’t boot anymore.
    I tried flashing again but it didn’t work.
    The sony logo appears and disappears. Please help met out

  5. Is this really the only thing to do, i read something about backup TA on Xda is this also neccesary? TY in advance.

  6. TY Anurag Kumar, for now you made my day.
    One more i am from the netherland ( dutch ) and i downloaded the version C6903 14.1.G.2.257 firmware ftf. is this the correct one.

    • while flashing finished, was there any warning in blue letters like “sim partition file not flashed” ?

      If not then try again.

      While phone boot loops and you see sony logo, then press volume down button and connect it to PC, try connecting like that to get out of boot loops and then again re flashing via SUS or flash tool.

  7. Anurag, got the phone working again but only after flashing whit the sony update service. All is well now, was worried for a while.

  8. Hi i have tried to do this installation on my sony xperia L . But When flash starts I get this message and it

  15. Hi, Anurag Kumar,

    First of all Thanks a lot for this step by step guide.
    I really appreciate your knowledge sharing idea.
    Salute to you brother.

    Only one small help. I am not able to setup exchange mail after I downgraded to 4.2.2 . It says “could not connect to server “. Also I used to use same settings before when I was using 4.3 and 4.4. But some how the same settings are not working with 4.2.2.

    Could you help?

  16. Hi Anurag Kumar, I’ve done exactly everything you instruct here. But, after successfully flashing my phone, it wont start. It just show sony logo and then nothing, just a black screen with back lighting.

    I’ve read this is a bootstall problem. Do u know what is actually causing this issue?

    Thanks

    For an estrange reason after the update my SMS icon just disappeared!!!
