Is it possible to ODIN the phone back to the previous update so that you can root the device?
I just got my s4 less then a week ago and it was already at MF3 :(
Having some issues with my Samsun Stellar... I couldn't load the 4.1.2 JB Update from Verizon on my rooted Stellar... So I tried to first 1) un-root then 2) flash back to the stock ROM then update. Option 1 didn't work, but Option 2 did.... Odin to stock rom, 1 small OTA update, then the JB OTA... worked like a charm. But once I got to JB, I couldn't re-root my phone.
