i337m (Bell Canada) Unlock codes not working - will downgrade fix this ?
I have purchased a S$ i337m on carigslist and it came with 4.3 - apparently seller did the official Bell update from Samsung, and phone was 4.2.2 prior to that.
I purchased unlock codes from 3 different providers (same codes) and they are not working. Also service menu not available, etc.
I wonder how does the unlock feature work? I somehow I found stock firmware for 4.2.2 , would the codes work?? IS unlocking done via firmware or hardware?
USB unlock also not working on this version due to added security.
