Hi,

I have added the changes in Linux kernel drivers and the driver for USB is not loaded and cannot be detected by QFlash as well as Device Manager in Windows.

So, now I want to recover this RG255C-GL module by start up with recovery partition then flashing again the correct image to active partition. Please let me know if you have any document to do so.

You can short the USB_BOOT with 1.8V ( vdd_ext) and power on the modem, there would show a QDloader device port and then you can flash the device with QFlash.
