Well… sometimes when you restore a TWRP Backup…
and try to enable/activate Private Mode… You get this error… "Failed to enable Private Mode"
Your only option at this point is probably a full clean ROM Installation… (or wipe entire data/cache) and start all over again…
So… instead of starting all over again (or throwing your phone)
You can do this:
BEFORE YOU CONTINUE!!! ALL YOUR PRIVATE MODE DATA WILL BE LOST!!!
USE THIS METHOD IF YOU WANT TO AVOID A CLEAN INSTALLATION…
1. Navigate to /data/system/ and search for:
– personalpattern.key
– personalfingerprintpassword.key
– personalpin.key
…and delete them all… (you might not have all 3 files, that’s ok)
2. Navigate to /data/system/users/ and search for:
– privatemode_edk_1000
…delete it….
3. Reboot… & Done…. Private Mode is now fully operational.
Good Luck!
