hrmm, maybe try this:
flash the modified format all
flash 2.0 again
reboot the phone
boot into CWM
flash 3.2.1
reboot the phone
Reboot a few times and let the phone set for a few after those.
Sent from my SPH-D710 using XDA App
I have no such issues with 3.2.1
Try running a cache cleaner, then boot unto recovery and wipe dalvik 3X....then reboot. If that down clear the lag, then try re-flashing ROM.
tried all those, still no good. I'm bummed cause v2.0 is so good.
I'm on the ek02 modem if that means anything.
