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.

Or remove the cover,disconnect the batteries,,then try
The cover will come off with plastic credit cards,no wires connected to the rear cover, it just unclipps,start furthest from on switch.

@gdegrez
The brom error, is sometimes because you don't have a good adb,connection.
Some BQ flash_tool versions have a short timer set,and you repeatedly get the brom error,before your device can do anything.
Can you try with a different flash_tool.
I use a chuwi 14.1 lap pad. It has 3.0 usb and 2.0.,works for me on either
If you are brave enough to take the cover off,you could try with the battery disconnected, then the flash_tool is not getting ( feedback) from your device
