Hello,
I had updated my C6802 to 14.2.A.1.136 someday through my Xperia Update Centre(in-built mobile app). But I wanted my mobile rooted. I found this thread(http://forum.xda-developers.com/show....php?t=2630781) which explained how I can root my mobile. I passed up to fifth step under "Coming from stock 14.2.A.1.136 or 14.2.A.0.290 with locked BL" part. But as soon as I realised the links of sixth step are dead I rued myself because of what I did.
Now I have rooted mobile but, first, in it's "About phone" under "Model number" C6833 is written while it's not my actual phone model, second, the mobile is not able to update and remained stuck at 14.1.B.1.532, third, it's not able to repair through Sony PC Companion, fourth, I can't go back to version I want with "Factory data reset".
1. I want my mobile back to what I bought in terms of it's software. I live in Iran if it matters for the firmware or other things.(Official software would be more favourable!), Is it possible?
2. Is it possible to convert these to FTF files?
3. If I could succeed going back to my default factory mobile software, is it possible to first root device and then update to 14.2.A.1.136?

I should thank you in advance, I do thank!

restore the TA backup if you made one this will relock your bootloader and get you the DRM keys back then download the ftf file for your device http://forum.xda-developers.com/show....php?t=2453921 then use flashtool to flash the stock rom you want !

if you want to root 136 then you should stay with the unlocked bootloader so skip the restoring TA backup part ! after flashing the ftf you can use this method http://forum.xda-developers.com/show....php?t=2631866 its short and easy

Don' worry when you flash the correct firmware it will go back to c6802

" the mobile is not able to update and remained stuck at 14.1.B.1.532"
"it's not able to repair through Sony PC Companion"
"version I want with 'Factory data reset'."
All the same issue:
Once rooted we normally have to flash manually as Sony's software won't update modified firmware.

1: not going to happen unless you un-root etc, but you want a rooted phone yes?
2: No.
3: You are already rooted, and it depends if you have unlocked the BL (or if you want to) on the next steps.

And I have updated the links in the guide to point at the DIR not the file si will work even if [NUT] updates the file again

Hey mates,
Thanks again for quick useful replies.
I had decided not to have a rooted mobile, the third question was only for my information.
But there are some other questions:
1. If I flash an official ftf and don't root/unblock bootloader, will I be able to update my android through Xperia Update Centre?
2. Is it okay to restore TA which I backed up when I was using a(n) rooted/older Android version? What exactly does the TA Backup do?

blueether, thanks for your answers and Guide Thread.
gcg000, thanks for your answer.

Restoring your TA Backup should be fine provided you do it through Flashtool, then if you wipe cache and dalvik then flash a stock ROM all should be well. If you restore back to stock as in Bootloader Locked and NO root then your phone will update through Update Centre and PC Companion as normal. Follow the instructions carefully when restoring your phone too!

Good luck and happy flashing!

gcg000, thanks for your answer.

if you used TA backup I would restore the backup with that, search for the guide on restoring you TA, it's around somewhere
