Hi Paul,
No need to open another thread, the first one is still active.
I understand your frustration, but you need a little patience we are mostly a community of volunteers and we do this on our own time.
It's holiday season and people might be busy. Give it more time, I'm sure someone will be able to help.
You can also check out telegrams channels to see if someone with this device is able to help you out.
I'll lock this thread.
Please continue on the original one:

Happy holidays
