I think I need to reinstall operating system

Hello, my router got hacked, and its in a MITM situation.
I managed to restore the base OpenWrt OS, but as soon as I connect LTE, to the network, I get infected again, and password, dns changed, etc.

So my Idea would be to reflash the OS to the stock version, and then, change the administratio credentials.
I don’t want to open it, since I could damage something.
My idea would be to find a way to access the web interface of the module, but with it in the router, and reflash from there.
I see that I have the tool qcm and quec_upload

This are the nodes I have:

root@router:~# ls -l /dev/cdc* /dev/sd* /dev/ttyUSB*
crw-------    1 root     root      180, 176 Sep  3 20:00 /dev/cdc-wdm0
brw-------    1 root     root        8,   0 Jan  1  1970 /dev/sda
crw-rw----    1 root     dialout   188,   0 Sep  3 20:00 /dev/ttyUSB0
crw-rw----    1 root     dialout   188,   1 Sep  3 20:00 /dev/ttyUSB1
crw-rw----    1 root     dialout   188,   2 Sep  3 21:01 /dev/ttyUSB2
crw-rw----    1 root     dialout   188,   3 Sep  3 20:00 /dev/ttyUSB3

This are some kernel messages:

I don’t find a way to see what is the module I own, but I know its a 300Mbps CAT6 mPCIe, I live in South of Europe(EMEA).
CAT6 Mini PCIe

I don’t see version option for uqmi command.
My router has USB and SD-Card.

I will need to find a way to access the web interface, to see what version I have but I don’t know how to access it, can you guys help me?

thanks in advance

hello,
I finally got the module I own:

Quectel
EP06
Revision: EP06ELAR03A08M4G

OK

I will need the firmware package
Please provide me also with a sha256sum checksum of the firmware.

Does the firmware is the same for any module revision in any country it applies or do I need to configure it prior to usage?

This problem has nothing to do with the modem and/or Quectel.

I need to re-flash firmware in my module.

Please provide me with the firmware for:

Quectel
EP06
Revision: EP06ELAR03A08M4G

Also it would be nice to have a sha256sum check sum of the firmware.

Thanks in advance
