I have an lg rebel lte from tracfone with android 5.1. I install a custom locker and then somehow set the system lock to swipe. Now when i try to unlock the phone it says systemUI has stopped and touch input fails. Tried reboot and and cant boot recovery mode. Please help!

You will need to do a factory reset to gain access to your phone. If factory reset don't solve the issue, you'll need to flash a stock firmware.

  • First, turn the phone off.

  • Press and hold the following keys at the same time: Volume Down Key  + Power/Lock Key.

  • Release the Power/Lock Key  only when the LG logo is displayed, then immediately press and hold the Power/Lock Key again.

  • Release all keys when the Factory hard reset screen is displayed.

  • Press the Power/Lock Key to continue or either of the Volume Keys  to cancel.

  • Press the Power/Lock Key once more to confirm or either of the Volume Keys to cancel.


Performing a hard reset deletes all of your user data, which includes pictures, videos, and music saved to your internal memory.
