@silvia @herbert.pan-Q I need the latest drivers for windows for RM500U-CNV. I also need to know if Qflash 7.7 can update it or if there’s any other different tool to do it, alongside the documentation for windows and linux. Thank you
Qflash v7.7 is the latest version and can handle the upgrade process. What kind of contents are you expecting the document to include?
Hardware manual and at manual
I have sent it to you by email,pls check
Hi herbert, I’m trying to install the driver Quectel_Windows_USB_Driver(U) and I am encountering the following issue, are you sure it is signed?
:
can you send also upgrade instructions for Linux?
Perhaps it was the security system on your PC that intercepted or blocked the installation of the driver.
Can you send me also the linux firmware flasher for this UNISOC device? QFirehose isn’t working.

[004:660] Upgrade module fail
Please refer to the instructions of QDloader.
Thank you, i looked at the .txt and I checked that the program was requiring QDloader -f FILE.pac. Now I’ve upgraded the module successfully.
AT+QADBKEY?
+QADBKEY: PKM058_2_7_21
OK
Can you guide me to unlock ADB?
I’ve tried as the other Qualcomm quectel modules, but it returns error:
AT+QCFG="usbcfg",0x2c7c,0x0900,1,1,1,1,1,1,0
+CME ERROR: 4
I will assist you in generating ADB on a working time tomorrow.
