***Xperia Miro (Mesona) - ST23i/a Official Firmware Files***




So, these are official Sony's firmware files for Xperia Miro. This is Sony's factory rom. These can be useful to unbrick your phone, return to stock, cook roms, update firmware, debrand your phone...and so on :D
These firmwares are generic. That means they are global - international - anyone from any country could flash them :D

Please remember that there is small chance of bricking your device - Flashing your mobile phone is fully on your own risk and I do not take responsibility for anything happened!



FAQ​
- Are these rooted? - No and these are not modded at all I haven't touched a thing (Sony original).
- Can I flash this on another phone that is similar to Miro? - No!
- Can I flash this on SIM-Locked phone. - Yes.
- Can I flash this on both Locked/Unlocked bootloaders. - Yes.
- Will this change bootloader or SIM Lock status. - No.



How to install firmware​
- Do not plug your phone to computer and charge it to 100%!
- Go to settings and enable USB Debugging and Unknown Sources.

1. Download ftf from post above depending on model.
2. Install latest Sony PC Companion (needed for drivers).
3. Install latest Flashtool.
4. Go to (C://flashtool/drivers) and install driver file.
5. Copy ftf to (C://flashtool/firmwares).
6. Open Flashtool.
7. Click on big lightning button.
8. Choose flashmode.
9. Choose correct ftf (left side), do not touch anything else and click ok.
10. Wait.
11. Image will show up on your computer - Turn off your phone.
12. Plug it in USB while holding vol- button (hold vol- until blue LED light blinks).
13. Wait.
14. When flashing finished text appears unplug your phone and turn it on.
- It may take a while to turn on (Don't panic).




Android 4.0.4 - Ice Cream Sandwich

Differences between ST23a and ST23i are different 3G frequencies. ST23a are phones usually bought in American Continent (I think north of America).
And ST23i is usually bought in Europe and other parts of the world. It is reported that if you flash one version on another everything will work.

EDIT: I stopped supporting this thread and deleted all Xperia Miro files from my HDD. I uploaded all files here one last time if they are useful to someone.

Custom roms will include root.
Also when cwm will be avalaible (with CM10?) we may could install root via cwm

    any mirrors or compressed files?

    No, I have very very slow net :(
    But I will change hoster for sure. And I can not compress this important files.

    And please do not mirror my links...

    Can sme1 re-upload both firmware on mediafire please...

    Thanks in advance.;)

    Yes, I will. But I am very busy right now...

    Can anyone please write steps i need to do in order to get from CM FXP211 to the stock ...5.5 version?

    1. Flash this using flashtool.
    2. Done :)

    can I just restore stock ROM with PC Companion? Without Flashtool? Because I never successfully did that with Flashtool... It said you don't have the driver installed bla bla bla... Please help me, thanks...

    1. If you have installed MIUI, CM10, or other ROM that include flashing boot.img using flashtool and unlocking the bootloader. No.
    2. If you have installed some variant of Stock rom (that works for both locked/unlocked bootloaders) - Example: Gimlo Yes :D

    But to fix your drivers problem do this:
    1. Install PC Companion
    2. Go to C://flashtool/drivers and install that.
    3. Reboot.
    4. Now it is ok.

    Now you have that 3 files? :( i have st23a but i dont want to repair with pc companion :/ i have a lot of apps and settings i dont want to loose all :/

    I don't have them. Nobody sent me and it would be very helpful for developers on this forum.

    Are you rooted? If you are you can use backup program from Google Play to back up your files, contacts, settings and so...But you must be rooted before and after...
