Firmware update only did partial upgrade?

[Agent24]

I have a PinePhone Manjaro Edition and it's working alright with PostmarketOS, but I do have some issues with SMS, particularly larger messages getting "jammed" and not receiving, until I manually delete them from the queue, wait some amount of time (sometimes even a day) and it will start working again. I thought this might be some modem firmware issue as I am running a very old version.

The original modem firmware was EG25GGBR07A08M2G_01.001.01.001

I tried updating to 01.002.01.002 with the fastboot command, but it only seems to have half worked, or something.
I used the information here: https://github.com/the-modem-distro/pine...LASHING.md

I got a message like this with a warning:

Code:

~/Downloads $ fastboot flash modem NON-HLOS.ubi && fastboot reboot
Warning: skip copying modem image avb footer (modem partition size: 0, modem image size: 41025536).
Sending 'modem' (40064 KB)                        OKAY [  1.281s]

Rebooting                                          OKAY [  0.018s]

When the modem rebooted, the version number was not 01.002.01.002, but 01.002.01.001 instead.
I tried upgrading to 01.003.01.003 and it's the same problem.

The given echo command to set the modem into fastboot did not work for me, I get an error that /dev/ttyUSB2 could not be created:

Code:

/bin/ash: can't create /dev/ttyUSB2: Permission denied

I used the following instead:

Code:

~ $ echo "AT+QFASTBOOT" | sudo atinout
- /dev/ttyUSB2 - > ./fboot.txt
doas (user@pine64-pinephone) password:
EOF from modem

Does anyone know what to do? Thanks!
