Updating a Rooted Verizon GS3
I just rooted and unlocked the bootloader on my old GS3 that I gave to a friend since I got the Note 3, and I just noticed for some stupid reason that it was only on 4.1.1, which I know isn't the latest firmware, so I was wondering if there was anyway to update while still rooted ? or can I use SuperSU Pro to unroot and then run the OTA and then re-root? If so, will this re-lock the bootloader?
Also what is the latest firmware available, OTA or Leaked ? I believe it was on 4.1.2 or something like that when I originally gave it to her. Is there a leaked version of 4,2 or 4,3 ?
