Vz Note 2, rooted with TWRP installed (used procedure over at galaxynote2root.com). I downloaded four different ROM's to my external SD card. When I boot into (TWRP) recovery and try to install any of them, I get an error that it can't unzip the file/file corrupt. I tried several SD cards, all formatted FAT32 and downloaded ROMs several times, same result. Someone suggested that I boot into TWRP and check for update, but it says it is up to date. Being new at this, I am at a total loss. Appreciate any help, but please explain it for a N00B!
