I have been reading and searching thoroughly the forums for the past weeks and I haven't been able to find a stock ftf file for Z(C6602).
I am trying to downgrade to 4.2.2(.67) for rooting purposes and to backup the TA, then to unlock the bootloader. I bought the phone during autumn last year, from Sony USA as an unlocked phone. I currently am running kitkat(10.5.A.0.230). Also, I am currently living in Romania and using Vodafone as a carrier.
I'm in need of a stock ftf file running 4.2.2 , right for my region. I couldn't find one that suits my needs. If anyone could find one and point me at it, that would be great.
Thanks in advance
