Bought my second used ZUK Z1 and the previous owner told me that it works fine but for the airplane mode.
So got the phone, flashed with QFIL two different CM12.1 images but the problem persists. It reads the SIM card but there is no signal reception as if the antenna is shut down...
I bought a used Zuk Z1 and I am faced with this message "Sign in with a Google account that was previously synced on this device"
Of course I cannot get the previous owners email, and when I try with my email, it just rejects the input.
I have wiped and reset the phone but to no...
