Xiaomi 2, after flashing from the V5 development version to the V5 stable version, contacts, dialing, text messages, file management, system updates, etc. cannot be used, and it crashes when clicked.

Hello, it is recommended that you back up important data first, then enter Recovery to clear all data. Do not restore data after booting up to see if the problem can be solved. (Backup: Security Center - Backup, back up the data you need. Clear data: In the shutdown state, press and hold the volume up key and the power off key, and let go when the startup screen appears. Enter Recoverygt; Chinese gt; Clear data gt; clear all data.)

Thank you for your support and wish you a happy life!
