75% of the time, the backups that I make of my ROMS won't restore. I boot into recovery, wipe everything, then restore. When I reboot system, it stays stuck on the splash image until I remove the battery. I need to repeat the process until it decides to let me restore one of the backups. It's totally random. One time, the backup won't restore and the next, the same exact backup restores just fine. Any ideas? I'm using TWRP recovery if that matters
