    So I had CM12.1 on my SGS4 and was working fine. Was giving phone away to someone so I want to restore to factory. Follow a guide that said use Odin to flash stock image. But Odin fails to flash. http://i.imgur.com/8TGQKsA.jpg & http://i.imgur.com/4dAXZEz.jpg

    Boot to recovery (twrp) and restore a backup I made before I installed CM12.1 Boot and was going to wipe data, but find WiFi doesn't work. Data wipe anyway, still same WiFi error: http://i.imgur.com/sTUj4Cg.jpg

    Finally break out Kies and try" Firmware emergency recovery".... but "List of devices requiring emergency recovery" is empty, so try "Firmware upgrade and initialization". Enter model #, enter S/N, try both HEX and DEC but each time get told the SN is incorrect: http://i.imgur.com/RGgXM5P.jpg

    I just want to restore this back to stock and have it all work, What do I need to do?

    What model s4 do you have?
    Are you using your SN listed on sticker under battery?
    Do you remember what Android version you were on prior to flashing CM 12?

    I have the Sprint version and used the SN from under the battery, but it was the same as if you look in the phone info screen. Before cm12 It was just rooted stock firmware.

    In Kies pic the SN looked to long and I thought you might have been trying to use the IMEI number instead of SN
