Hi friends, today I will show you how you can return to official firmware on Sony Xperia U.
For various reasons the latest versions of Android (4.0.1 ICS), which came in the form of updates to Sony Xperia U, make phone to move all bad. It seems that Sony's software engineers have not paid enough attention to older phones, I say this because the Xperia U versions of ICS or JB moves excellent (Cyanogenmod), while official ROMs are made in a hasty park. Probably blow them compete in the neck and can not concentrate ...
The first version of the firmware that came with the phone was the most stable and therefore today we flash-ui on that, that's a version of Android Gingerbread firmware 2.3.7, perfect even for those with the need to connect to server IP Voice.
Careful:
This method can be applied only on the Sony Xperia U will not work on other phones.
Why do we need?
1. USB Driver (flash mode)
2. ROM format "FTF"
3. Flashtool

You will need to patiently armaments, some files will download quite difficult.

  1. Thing you lose is not adverse guarantee you say you do not miss the contrary lose, because I talked to Samsung and told me that I wanted to give back to 4.1.2 2.3.4 and I said can I give to Odin and firmware The original says "if you do lose your guarantee that operation, we recommend that you take it to an authorized Samsung that you can do that" - officially. Cristi you look flash but I tell you that if you take him to see that it was Sony or 4.0.1 4.0.2 and tell him how you give back to 2.3.7 and you say yes Flashtool mean losing your warranty, you pay a repair. Like the Samsung N7000 yours changed the motherboard of it, as that was taken just had nothing on it was destroyed by flash incorrect normal uirea not start at all. I say what I said that Samsung's not to do with Odin as losing the warranty. And one last thing I even met the Pope battery in galaxy s2 5 100% min was busy watching me on YouTube after I 80% laso say hell the battery it's a little swollen so it seems to me and I gave 2000mAh I formatted memory factory reset it 16GB I wiped everything, and I removed the SD card A-DATA Class 16gb 10 and you load that consumes it, I uploaded on Youtube 100% go see 97% say "oops "something goes wrong, as I've had problems with cards A-Data class 10 are all bad, I had one on an IP camera, lock my room and I put on both Verbatim 32gb class 4 and phone and cam go Razor, I have no problem. I for one do not recommend A-DATA microSD cards bad, my papa goes battery even tough phone was to go with the battery and bn as I went there.

    Yes ... the truth is that ZTE is a very popular company.
    More informed yourselves before you buy a smartphone, make a search to see which brands the more "flexible" development with a rich world of popular custom ROMs.
    Buy all no-name sites and claims to have run iOS or what not operating system.

    She may be popular (China is a huge country, may be even as the number of sales Samsung), but it 0 qualities.

    I say read my comment more carefully. I used the words "not good".
    There may be good things but a horrible marketing / weak which does not enjoy popularity as they deserve.
    Regardless of the brand (there is even Samsung models) there may be models not addressed in forums that are weak or are not loved by developers.
    Concluding, development and popularity in the world for any model ZTE Android is much lower compared to Samsung Galaxy S2, S3, S4, Galaxy Nexus, Nexus4, HTC One. Furthermore ZTE's models will not find anything.

    In the sentence "Yes ... the truth is that ZTE is a very popular company" was ironic. You hardly catch!

  23. Hi,
    How do I know if it's installed Flashtool is for Wind on 32 or 64 bit? The link does not specify nowhere indicated distinct positions download and app saved me just called "flashtool-0.9.13.0-windows".
    I see the tutorial is clearly visible on the desktop Flashtool 64. Or you've saved it?
    Merci ptr answer, I would like to begin the process and I encounter this problem (I Win the Ultimate 7 32 bit)

  24. I have the same problem with those above.
    I am told that the driver did not fail even installing it manually.
    I'm going to Portable Devices, see my phone, give update driver software, browse for driver software, let me pick ... etc. .. and I give browse and choose that driver tells me it does not contain a compatible software driver for Win on 32 bits. I installed including ADB Driver Installler tells me the phone I installed Android ADB Interface but not rhesus anything. Any solution? We respond and new one, or just are "pulled ears" as "developed tutorial"?

  25. Glad to see that the fix by deleting the comments bother you.
    It would be easy to assume the courage to say "no yet know what answer to give"?
    Sin. Watching with interest your site.

  26. I managed just after your instructions. Thank you very much. I got rid of embarrassing and applications from Orange so: Thank you very much once again.

  27. Hello! Regarding the problem with the drivers, you will appear as drivers not installed, go to the directory where you installed the flashtool (usually location C: \ Flashtool) into the folder "drivers", giving you double click "Flashtool- drivers ", click Next, and looking at the end of the list there 'Flashmode Drivers", check it and finish the installation. After that, run the flashtool, connect the phone by pressing the volume down, and it should work perfectly. I hope I've been helpful!

  28. And of course, from the "flash" -> flashmode -> ok -> sourcefolder (location where you 'Xperia U st25i_6.0.B.3.184 (GB 2.3.7) _Generic USER "and then click on flash.

      Install drivers listed in the tutorial? You gave a restart after installing drivers? Are you sure that the USB data cable is not broken somewhere? Use the back of your computer USB ports that come directly from the motherboard and not the front USB ports (in front of)
      You have disabled security software (antivirus şifirewall) before you start installing the drivers?
