Manually flashing firmware
I previously had a version of Lollipop 5.0.1 on my device (i9500) prior to flashing it to the original carrier-branded 4.4.2 version of Jelly Bean the phone came with (I planne on selling it.) After doing so, my S4 no longer recognizes SIM cards. Now, after investigating this issue I can see it can occur for myriad reasons, but my question is, could it had had happened as a result of a botched flash job? I only ticked "AP" within Odin when flashing the *.md5 file; should I have had selected all other options (i.e. BL, CSC, etc.) as I was reverting to a previous version of the OS? Could that be the reason the phone is no longer working properly?
