I have an BLÜ Pure XR with a broken screen (completely black) which I'm trying to put to some use (security camera perhaps), however, since I can't access the phone at all, I'm not able to turn on USB Debugging, and all strategies I've found online (including putting the phone in ClockWork mode, which I seem to have done successfully) using ADB yield "Permission denied" errors in one form or another (
mount: Permission denied,
adbd cannot run as root in production builds,
...java.lang.NullPointerException: Attempt to invoke interface method 'android.os.IBinder android.os.IServiceManager.getService(java.lang.String)' on a null object reference..., etc).
I say I've successfully put the phone in ClockWork mode because if I connect it to my PC via USB and I run
adb devices shows me a device in the list, and some of the errors I get include "BLÜ Pure XR" in their contents so it seems to be somewhat successfully connected.
Am I attempting to do something impossible?
