Hi. It breaks my eOS by making the Settings app crash, immediately after it has been started. I also had a similar problem with some Bluetooth app. And yes, I had to unlock the bootloader and I simply flashed TWRP.
I’ve used ADB before, and Rooted Debugging is activated. I don’t think it’s such a good idea to make a backup of a life system, because it may change while it’s being backed up, resulting in a inconsistent backup. And the data being backed up might be in a “running” state.
So I went into the eOS-recovery and tried ADB. I had to chose a menu item called “Enable ADB” or something similar. Then I could run “ADB shell” on the recovery. The idea is, that making a backup (by pulling the whole /data partition) would be consistent when done while eOS isn’t running.
But the /data partition wasn’t mounted. I tried to find a manual for the e-Recovery and found a lot of Howtos and special instructions, but no manual… I’d rather not play around and try everything out, without knowing what I’m doing.
I’ve had a look at the XDA thread you mentioned, but it seemed very involved.
Cheers, Volker
