How to Fix Bootloop/Softbrick

WARNING


Make sure to create backup of your files, sms, contacts, apps and settings as this guide might delete the files of your phone (excluding sdcard). Installing custom recovery or any software modifications will void the warranty of your device.

You can also send your device to Cherry Mobile Service Center if you are not confident and skilled enough to fix your unit. Although most of the time, repair of your unit/s might take weeks even months.
