I would like to flash back my erom to R3A016 is it possible??. I've got problems with simlock, i can't patch it. I've put patch correctly(just like in tutorial, no errors) but simlock didn't came off. So i would like to take it off on older soft version, but older soft creates wsoe.

I would like to flash my k800i to k810i, but i don't know if it can be done on that EROM R3A022.

K800i DB2020 CID:52

P.S. sorry for my english, and i'm just starting my adventure with upgrading se.
