I just flashed TWRP v2.7 on my One. Tried making a backup but it keeps failing while backing up the data partition. It doesn't give any sort of error code or indication why. It just stops and says "Backup Failed". I flashed back to v2.6.3.4 and the backup completes fine. I noticed that w/ v2.6.3.4 it breaks up each partition into multiple files. It doesn't appear that v2.7 does that. Not sure if that would matter. Also, I'm still running stock 4.3. Does v2.7 only work with KitKat ROMs? I know v2.7 just released & there could be some bugs, but wondered if anyone else is experiencing this. Here's my getvar all just in case.
