Umi Super stuck during booting

Michi175

After shutting down due to running out of power, my Super will no longer reboot now that it's fully loaded again.

It first displays the Umi Link To The World screen, followed by the black screen with the white android text. And then it just stops and gets stuck at this screen forever.

I can only turn it off, but then on rebooting the exact same things happens. I already removed SD and SIM card, but to no avail

I was running the latest official OTA updates, never rooted or installed anything except OTA from Umi

Hi
I presume that latest OTA update was to Android 7.0.
By my opinion phone can't restart due to error in nvram.
You need use SPFT and flash you system.
Here you have SPFT updating procedure.
Please try with uncheck user data if you don't want lose your pictures etc.

And here you have all available ROMs

If this doesn't help you need change updating firmware option to format + download.
After that you need use SN writer to restore your IMEI numbers

Thx for the answer. I guess my initial post was missleading. I did not want to say that the phone stopped working in direct relation to an update that was done just before this error happened. Just that I was running on the latest OTA version before, but the last update was weeks ago and the phone did work perfectly fine all the time after that.

Unfortunately all this SPFT stuff doesn't work for me, as I can't get the PC to recognize the phone. It appears for a split second in the device manager with an exclamtion mark and then immediately vanishes. I already tried a different USB cable but to no avail.
