Please use this method if install fails in TWRP. This zip should be compatible with both non SAR and SAR devices too.
Usage: 1. Make a folder in the internal storage named "backup" 2. Extract a migrate backup zip file inside the created "backup" folder. The contents of the zip must directly be inside the "backup" folder 3. Don't extract multiple zips. 4. Download this file, open TWRP and flash this file (twrp_extract_SAR.zip). 5. Reboot and continue restore via the helper app.
