FM350-GL wwan and Fedora 44

Hi,

I know this modem has been discussed in another topic but I don’t really encounter thé same problem and I probably need first to understand if the modem is faulty or if it is not flashed correctly or if fedora is just not compatible with it.

So this is on an assus expertbook. So no special firmware in the bios to unlock like in lenovo that I am aware off. The modem should be then recognized and been available as it is.
If I am wrong just tell me of course.

The modem is a FM350-GL which translate into a mediatek chip 700.
The card is recognized in lspci
0000:58:00.0 Cellular controller/modem: MEDIATEK Corp. T700 5G Modem [5G Solution 5000] (rev 01)

The lsmod or the need of drivers by the kernel is also recognized.

lsmod | grep 7xx
mtk_t7xx              204800  0
wwan                   36864  1 mtk_t7xx

The modem though stays in fastboot mode according to /Dev
wwan0fastboot0
Fastboot and Adb command does not give me anything devices to interact with. So even if I had a firmware to push, which I don’t, I would not be able too.

fastboot devices -l
post@crohn:~$
 adb devices -l
* daemon not running; starting now at tcp:5037
* daemon started successfully
List of devices attached

post@crohn:~$

There is after all very little documentation on this, so any ideas are welcome.
The goal is to succeed into put the card out of fastboot mode and so have the modem recognized by network manager.
After that I will need to check the second big step which is the connectivity of the devices and the applications of the APN or understand how to upload an esim into it.

any ideas? Do I need to order a new one?
