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!
