try this
1) flash simple blue/green 3.1 and let the phone boot up all the way
2) boot into cwm and flash 4.1
3) clear dalvik and wipe cache, DON'T do a factory wipe
you should boot up fine now
edit
lol, guess you got it working =p
yep, so what is the standard waiting time to determine whether or not your stuck in a boot loop vs. just needs an extra load time to load up new theme?
1 min, 2 mins? 3-5??
i get jumpy after watching bootloop for more than 1 min and can hear things force closing (and vibrating) in the background
btw does everyone know a neat trick to get out of a bootloop? hold down power button until it shuts down, (and hold vol up if you want to reboot into recovery)
