I am trying to perform an ADB backup but I got stuck at the step where the phone receives the request of backup from the computer (the command I used on ADB was
adb backup -apk -shared -all -f F:\Android backup.ab).
It is asking for a password as in the pic below (sorry my phone is in Chinese, I will translate the dialogue below):
'The system has received a request to backup all data to the computer; do you allow this action?
If you did not request to do so, please do not allow this action.
Your phone has been encrypted, therefore you must encrypt your backup. Please enter password below:'
I actually forgot that I ever encrypted my phone; and I certainly don't remember having set a password for the encryption (I use the unlocking pattern in daily operations). So I thought this is to set a password for the backup action.
But as you can see, I typed some words in, but the 'Backup your data' at the bottom right button just wouldn't respond no matter how many times I pressed it. (I pressed the 'Do not backup' button next to it and it quit instantly, so I am sure the screen is reacting to my touch alright)
Would anyone mind lending a hand please? Thank you so much!
