Hi there! After flashing the JB version of CheckRom I've decieded to return to the Stock Rom of my Carrier. Then using Odin3 v3.04 the phone get stucked in "NAND write start" status. I have tried flashing another Official firmware, plus flashing siyah kernel .TAR to get access to CWM and flash from there, but all my attempts failed. Any suggestions? Thanks.
