k770i debrand help

[king_jamie]

I recently purchased a k770 it was working fine then it turned off and wouldnt turn back on. So i used the sony tool to restore everything via usb. it started working but wasnt unlocked on 02 and was on some foreign network and in Slovakian langauge. Im trying to unlock it on all networks, im a newbie at this so i dont fully know what im talking about here is what i get when i connect on XS++:

Read here : Flash K800 CID53 with K810 software CID53 (for begginers) - Top Sony Forums but usefiles only for K770 and skip from the 13 point

Do XS support CID53 cellphones?

I think, it would not (only up to CID 52)
