Unable to install custom app, Herelink read-only

the only thing i can think of is to factory reset the unit, and then try reinstall the app. I asume no other mod’s have been done ot the unit. It seems whatever the issue is, is a system wide issue, and the debug log’s arn’t highlighting what that might be at this point in time.

I performed the factory reset and am still seeing the same problem.
Following the reset I enabled Wifi and ran the update check. It said I am at the latest level (BRU01211104). I then enabled Developer Mode. And Enabled USB debugging. But the attempt to install the sample app is the same.

app-release.apk: 1 file pushed, 0 skipped. 83.8 MB/s (80251 bytes in 0.001s)
adb: error: failed to read copy response

is it possible to get a copy of the original apk? feel free to PM me with it if you think its more approptiate?

When you say original I assume you mean the original APK that I created and first ran into this issue. If so I can send it to you directly by don’t know how to do it exactly since it is 25M

my normal suggestion is
google drive
one drive
drop box
or similar service

problem ended up being the usb cable in this scenario.
