Mx2 boot loop??

    Mx2 boot loop on Jarvis screen running libreelec. Happen once is there any way I can back up with my build in case this happen again? Or is there a way to stop it from happening again?

    No one here provides a build for MX2, you should ask a person that provides the build.

    That said you should be able to make a backup using TWRP or ClockwordMod if you can find one for your device.
