Hi all, I need send my m8 back to htc for warrenty repair. I bought it standard and unlocked bootloader and gained s-off. Also flashed twrp recovery and custom ROM. I network unlocked it myself using a zip you flash in hboot as it was on O2. The cid is 11111111 so finding a stock using the cidndoesnt help as I can't remember what cid it was before. Can anyone help please? Can i use any cid stock as i unlocked to any network? Thanks very much. Ashley.
