flashing back and forth between custom rom and stock for updates?
I am wondering, when I had the Epic 4G, there was a stock rom that you would keep on the memory card and reboot in to that stock rom to enable profile, PRL updates. If I root my Samsung GS3, is there a stock rom that one can keep on the memory card and boot occasionally in to that rom to update PRL and profile? When I had my phone recently rooted, I of course could never update the rom, PRL or profile for Sprint.
