Knock on is not working on my LG g2 from past 2 days. I tried factory reset knock on/off toggle, device test, calibrate sensors. Finally I decided to return the phone but I need to unroot it for that.
As I cannot follow the usual process because my phone is not recognized in download mode via USB (both pc/linux) I tried installing a stock rom(80020k) and then uninstall the root. also I replaced the rtc files and the I tried to update the phone to D80020u but it fails with error saying device is suspected of rooting.
I became over smart and flashed a stock recovery which won't function.
No root, No recovery now. Tried rooting with ioroot25 doesn't work because it requires a functional stock recovery.
Any help/suggestions that can get me back to stock?
