qcell modem id
#1
So i have run into an issue with the fwupdmgr when trying to find the modem id. I go to get devices and it doesnt bring back a actual manafucture of the modem to upgrade it, all it gives me is a whole bunch of nunbers. Is there any thing i can do to get the device id of the qcell modem so i can upgrade it. All i see is letters and numbers. thanks

maybe slightly more information about letters and numbers should have been given.

lsusb givers following.

Code:
# lsusb
# in normal mode
Bus 00* Device 00*: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem
# in edl mode
Bus 00* Device 00*: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

my guess is that you have to manually reflash the modem chip, look following.
https://github.com/Biktorgj/quectel_eg25_recovery
or
https://github.com/the-modem-distro/pinephone_modem_sdk

try to get to the edl mode and flash it. maybe fastboot flashing might still work.

modemmanager usually messes things up during flashing and minicom, so i recommend following, or similar on some distributions.
Code:
# with sudo
sudo systemctl stop ModemManager.service
# with root
systemctl stop ModemManager.service

I checked lsusb and it still doesnt bring me back the manufacture, and when i go to check the product id and manufacture it keeps giving me the same id for all buses and products. it keeps saying manufacture is dantnix 6.6.6-1

nvm found it

starting to sound that, modem chip is more or less dead.

try different distro, maybe from sdcard. but i have feeling that you need to use test points to boot into edl mode, and flash it that way.

Yes, you can upgrade Biktorgj's firmware to a newer version. Just use the flashall script or do the steps per hand, see https://github.com/the-modem-distro/pine...LASHING.md.

It should also be possible through fwupd, if and when the new version is available from the LVFS (Linux Vendor Firmware Service). 0.7.4 is currently not offered there, probably because some people say it is less reliable than 0.7.2. (And 0.7.3 is not offered there because it is broken, 0.7.2 or 0.7.4 should be used instead.)
