Just checking if anyone faced an issue with "Android System: User Data Locked" on Huawei P30 Pro.

My Huawei P30 Pro got locked after a middle-of-the-night auto-update. I keyed in the usual password the next morning but the login failed. I tried all different passwords and it still doesn't work. To make matters worse and for whatever reasons, the phone went into airplane mode after a few restarts of the phone.

I cannot afford a factory reset as it contains all her work and personal stuff. We went to Huawei Service Centre and they are unable to help as well.

Any way to force kick the phone out of airplane mode?

  • Welcome to a Q&A site Android Enthusiasts Stack Exchange. There are a few suggestions on a big Google's Android Help thread, ranging from inputting the Google Account's password, restarting, shutting down and waiting for a few hours, and lastly inputting the last password set up on an app. Unfortunately, I'm not sure if airplane mode can be toggled from the notification drawer while locked or not.

Safe Mode From [HOW TO ENTER SAFE MODE ON HUAWEI P30 PRO](HOW TO ENTER SAFE MODE ON HUAWEI P30 PRO)

  • Turn off the device.
  • Press and hold Power button.
  • Tap Restart.
  • When the device is restarting, press the Volume Down and Power buttons simultaneously.
  • When the device logo appears, release the Power button and continue to press the Volume Down.
  • If you see Safe Mode in the lower-left corner after the device restart, Safe Mode is on, otherwise you need to repeat the process.

If you can get into safe mode then one of your apps is the problem. You can try deleting them, starting with ones that don't have of your data.
