I'll preface this by saying my replacement SII, which was probably a refurb (original developed a faulty power button), occasionally started freezing a few days ago whenever I'd use the back or home button to exit an application. A minute or two after the phone completely freezing, it would reboot on its own.
Anyway, I used Odin to flash FK23 (rooted, all data wiped). It went fine, I restored my GO Backup, and played around with it for a little while; it seemed to be running smoothly. Then the phone's screen went black and required that I pull the battery to restart the phone. I figured it might be a problem with FK23 so I flashed FI27 (rooted, preserve data). It went well until the phone froze during the boot process at the "4G" screen.
I pulled the battery, then tried flashing the stock version of FI27 (in case I have to take the phone to a Sprint store). The flash went fine, but it's still hanging at the "4G" screen during the boot process.
Any suggestions on how to fix this or what might have gone wrong? Holding power+down vol still gets me into Odin mode...
