[Q] Xperia u back to original. - Sony Xperia P, U, Sola, Go

Hi. I have a rooted xperia u.
It says
kernel-version:
2.6.35.7+
[email protected] #1
Build-Number:
6.0.B.1.564
It has been a long time ago, so i dont remember wich program i have used.
Now there is new firmware of sony (android 4 now i have android 2)
But i can't update it via the original way with pc companion it says i dont have a official version.
I want the original version, i have searched alot but i couldn't find any solution. thats why i made an account for xda.
I'm not sure this is the right forum to ask so plz correct me if i did it wrong.

I think the thread is right But can you tell me/us if your bootloader is locked or unlocked? Of course if you can

The program is called Flashtool by Androxyde & Bin4ry, heres the link: androxyde.github.io
NOTE: If your bootloader is unlocked do not accept any Over-The-Air updates or through PC Companion/Bridge, that's why you got the error

Thanx for the reply, i went to the site mentioned and i see 10 links with diffrent software (i gues) and the link to the flash tool is death
If i try it with pc compannion it downloads the software, then it says shut your phone down.
then hold volume down and reconnect the usb.
I did that but then PCC says i have the wrong software on it and it can't be updated.

Flashtool has new site http://www.flashtool.net
If PC Companion already download the files you can build the FTF file and flash with flashtool.

I have installed flashtools now and have located the files downloaded by PCC
im useing the tutoral, and i am at step 6 but i cant click on advanced.
There is a SEUS decrypt option at tools but that wont let me select the files.

---

Is it right?
Hi,
I have tryd it with:
tools -> bundle creation -> browse location of files from PCC
Device: Xperia U
Branding : None
Version : version PCC says is available.
Is it the same as selecting the 3 files?
it has made a file called:
Xperia U_6.1.1.B.1.54_None.ttf
And if its right how can i flash it to the phone?

---

Click SEUS Decript, then the 3 dots right to source folder and navigate to the blob_fs folder select it and ok.

Yes it's a bit different with new flashtool but the result is just the same flashable FTF dilr.
Just click the flash icon in flashtool.and flash this file in flash mode.
EDIT: Exclude TA if it's in the file, just to be safe.

is it supposed to be done in 1 seconds.
I shut down the phone and connect it while holding volume down it says:

LOL I immediately disable chrome on my phone.
Which is it ICS or JB? You may be lower on ram now so it's good idea to uninstall apps you don't use and disable services/apps you don't need
