If you look at the left lower corner of flash_tool pic, it shows no chip info, so you did not have adb connection.
Glad you got it sorted

The Umidigi A 5
Is out now, it has some good specs for less than $100. US
Any good for porting ,it comes with no bloatware and android 9.

@Lakotaubp Thanks, I was trying not to mention the almighty $, hoping a dev would pick them up

I have a Pro 5 ( ubuntu originaly)
and a Bq m10fhd (it has the losing password fault)
owned by a nonsmoker, old retired guy ,so these are like new with original boxes.
in Tennessee usa,
anyone interested before they go on Ebay

I remember my m10fhd did strange things when using a different phone charger ,for convience, there must be some discussion of this ,earlier.

Try viewing,“ xxx.skyneel.com” and search for, nvram error. ( replace x with www)
This should explain it for you

@fred56
Look to see if you have an imei number.
This is shows in android, as nvram error x 10
This usually happens if you use the flash _tool
and use the ' format all+ download ' setting.

Try searching ubports

An app,in Productivity ,section, 'active screen' could come in handy to keep your app 'open' when needed.

@gdegrez Glad you got it working.
