I was on a stock ROM and decided I wanted to try a custom ROM so using TWRP 22.214.171.124 (latest) I created a ROM backup. I had trouble flashing roms using TWRP when the ROM was on the extSD card and I had copied and pasted the file. Once I downloaded the ROM through the phone and flashed from the Downloads directory on the internal storage it finally worked.
So now I want to go back to my stock ROM. I have a copy of the backup on the internal and external SD card. Neither restore will work. Every time it trys to "Restore Data" it fails. Now I am in Recovery mode with no OS and no ROMS on the internal storage.
Any idea why the restore won't work and if I have any options with no ROM installed?
