thank you your reply.
the Modem test does work on both devices.
Braveheart shows on registration my provider, 3GB Model shows not registered.
Here is a picture of braveheart factorytest:

and here from 3GB Model:

Currently I can see 2 differences:
1. BH uses an older Firmware
2. BH uses LTE BAND 3 and and the newer firmware tries BAND 20
(also the signal strength is a little higher -71/-79 dBm)
So my idea is to try a downgrade to the braveheart version.
Do you think this is a good way?
That said I'm interested to compare the firmware versions on my BH and 3GB PP with yours later tonight and will let you know if theres a
difference or if discover anything else.
Also, I should mention that at one point I contacted Quectel customer support and that might be a resource for you. They made available an EG25 flashing utility and firmware. I did not use it as I ended up flashing the EG25 using biktorgj's method.
They also recommended their Quectel forum. https://forums.quectel dot com/c/knowledge-base
