I was given this firmware by Quectel support (RG500UEAABR03A04M4G_01.001.01.001)
Firstly i was able to plug in the USB and install Quectel_Windows_USB_Driver(U)_For_ECM_RNDIS_V1.0.14 which gave me a bunch of COM ports and USB modem functionality. Using the AT driver and PORT number i was able to send AT+QDOWNLOAD=1 and reboot the device into a working recovery mode. I then used QFLASH (latest version) to send the above PAC file to the device.
After reboot, the modem no longer starts, i can still login through UART session and login with ‘user’ into a highly restrictive shell. However the modem functionality doesn’t work anymore. there is no LAN/WIFI, and the physical RESET/WPS buttons no longer work.
Any IDEA how i can restore this device or get the modem working again?
When i boot up i am able to go into DEBUG mode. Where i have captured the logs…
Yes I sent AT command QDOWNLOAD=1 QFlash v6.9 seemed to work and was successful how ever after flash the board WiFi / networking doesn’t start up however it still boots up and I can log into user shell via UART pins located on top of picture
Hi @Bean.Wang-Q I am looking at this file Quectel_RG50xQRM5xxQ_Series_AT_Commands_Manual_V1.2.pdf i dont see anything about turning on Wifi module. Is this the correct document? Yes its open solution and i am root through ADB
Hi @Bean.Wang-Q after following the doc and running the command “./quec_wifi.sh” i get the following error?
Starting quec wifi
insmod: ERROR: could not load module /lib/modules/4.14.98/wlan/wlan_cnss_core_pcie.ko: No such file or directory
insmod: ERROR: could not load module /lib/modules/4.14.98/wlan/wlan.ko: No such file or directory

./quec_wifi.sh: line 6: iw: command not found

./quec_wifi.sh: line 9: hostapd: command not found
interface wlan0 does not exist!
finish quec wifi start ap
I also tried to run the AT+QWIFI=1 command which returns
There is no wlan0 and no wlan.ko. For open solution, it might need special driver.
If It is open solution, it is better to check with the Quectel FAEs. For open solution, you must have e-service count.
FC06E is PCIe device, you can check whether it is recongized.
With which firmware it worked?
On the forum, the Quectel can only send you the standard firmware. They cannot send you the QuecOpen SDK and firmware.
Hi @Bean.Wang-Q i think i know the issue, the system is missing lots of kernel objet/ drivers, however i will have to compile these from linux source code and other places like pcie drivers. However the firmware (RG500UEAABR03A04M4G_01.001.01.001) doesn’t have the GNU toolchain on it. So there is no MAKE or GCC to compile source. I also tried to install packages via OPKG, however all the packages i try to use say wrong architecture. Do you know how i can find GNU tool chain and get GCC and make on this board or know where i can find OPKG (*ipk) packages for this?
