UMI Plus upgraded to Android 7 - Stuck in loop

AlexL

My phone Plus was upgraded to Android 7 via a notification. After briefly working with the new system it stopped recognizing my SD card so I did a factory reset. Now it is in a loop with an android screen coming and going every few seconds. Basicly the phone is now unusable.

Any idea on what I should do? Can I / should I go back to Android 6? If yes how can I do this? I was realy happy with my phone before this problem...

Hi Marcin,
Thank you for your reply.
I have followed the procedure for Android 6, however now my phone will not turn back on... The battery is fully charged.
Is there a trick on getting it to turn on?

Firstly you should flash your system and use latest ROM from here
Android 7.0

Hi Addos,

Thank you for your reply.
I tried "Download Only".
I am not sure what custom recovery is.

Repeated the procedure but instead of ¨Download Only¨ I used ¨Format All & Download¨. Phone now is back from the dead!
Thanks for the assistance.

Hi
After format + download probably you loose IMEI numbers (only 111111 or 2222222)
To restore IMEI numbers please look here
