After rebooting (CM 11 installed with 22.214.171.124 CWM) and unlocking the screen lock, the error showed up again. After dismissing it, I got another "google.process.gapps has stopped" and then "google Keep has stopped". Some seconds later, there was an error notification in the status bar (backup account needed) and another bunch of errors. I was unable to even get to the drawer, because the erorrs were showing one after another instantly. Finally, the phone crashed (I think...) by suddenly displaying cyanogenmod boot screen (it was stuck this way for 3 hours before the battery ran out). I tried rebooting it again a few times, but with the same outcome every time.
My first guess was to re-flash CM11. After full wipe and install from zip (no errors) the phone booted up... right into the system I was using minutes before, with the same wallpaper, pattern lock, theme and problem described above. Then, I tried some solutions found online such as:
1. flashing CWM (no effect; even worse, when I tried flashing older version to see if anything changed, it was still the newest one!)
2. flashing diffrent ROM (liquid-smooth, no effect, still CM11)
3. flashing stock kernel
4. flashing stock ROM
I gave up for two weeks, but today I tried again flashing CM11, but I received status 7 error (liquid-smooth got "some syslinks are missing")
I'm slowly running out of ideas, now I just want my phone to run ANYTHING. Please help me, because I think I tried every solution from XDA and nothing worked.
