Is this something I should try?
@merlin, In my firmware flashing account in the (https://forum.pine64.org/showthread.php?...647&page=5) thread of using biktorgj's firmware flashing/recovery software, my Braveheart's modem had always failed the factory modem tests and the sim card was never detected in the initial and enhanced PMOS factory tests as well as various OS's Mobian, UBPorts, and PureOS.
Does the modem test fail with the PMOS factory test or is your (known to be working sim card) detected by the PMOS Factory test or any of the other OS's you've tested?
If the answer is yes to the former and no to the later then IMO your reflashing using biktorgj's method as described in my https://forum.pine64.org/showthread.php?...647&page=5 account might be worth trying.
Please note that in my BH's case although the process (from all indications) completed successfully the firmware flashing did not fix the EG25.
I'm sure there is some risk in flashing but if your modem's firmware is corrupted then not sure what one would be clinging to unless it could possibly bork other functionality in the device. Others might have an opinion on this risk if any. Good luck and let us know how you fare.
