Trying to fix the PinePhone Pro Modem…Again
Table of Contents
Think I finally got the pro modem working again. Not sure exactly what I did that was different this time, seems like I'm always on the same blog posts and trying the same recommendations. For posterity, this time.
Preamble
From the Stock firmware recovery for Quectel EG25-G I ran
./flashstock
And then in a separate terminal entered fastboot by running
echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2
Now, this seemed to work. Couple vague warning messages but no real errors. Not 100% sure if this first step was necessary but including here since it was done.
EFS Recovery
Ran the EFS Recovery playbook. Will include the steps
- Download EFS Recovery Package
- Enter fastboot w/
echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2 - Unpack recovery package
- Flash custom bootloader and boot:
fastboot flash aboot appsboot.mbn && fastboot reboot && fastboot oem stay - Flash the placeholder sysrev image:
fastboot flash sys_rev sys_rev.bin - Rebuild your IMEI:
fastboot oem fix_imei 12345678901234(IMEI is shown on the back of the heat shield) - Boot modem:
fastboot continue reboot
After this I popped in a SIM card, booted into my PostmarketOS/Phosh install, enabled Mobile Data, made a call and sent some texts and everything worked.
