I've been usin TWRP for the longest time, on my sgs III and Note II. All of a sudden last week I go into recovery to flash an add on and I get a boot loop in TWRP. Couldn't even pull battery and boot system back. Had to odin CWM, then I updated the TWRP script and would still get a bootloop. So I odin'd back to CWM again and staying for the time bein.
Anyone have any idea why this would happen?
Currently on My Rom 4.1.2.v2
hmm really? Never encountered this myself. It's hard for recovery to get corrupt, unless the addon messed up that partition. Are you on the latest version (2.3.3.1) ?
It's not so much the recovery that's corrupt, but the /data partition I believe. I had the same thing happened to me a few days ago (couldn't even backup my ROM). Formatted /data and recovery worked again. Try backing up your ROM in CWM and if it reboots before it finishes, you'll have to format /data through recovery. If you do happen to do so, backup all of your files in your internal storage since EVERYTHING in it will be wiped clean.
