Thanks for informing.
Currently I'm vacation.
But after my return I'll analyze the situation. I belive we can change the scatter file for the first flash operation to include the modem partition.
Question: it is possible after upgrade to 9.0 return to 8.1?
Of course based on a full read back from actual 8.1 firmware.
The removing for red sign about opening the bootloader is a good idea, but should be possible with a normal factory reset or not?
