After using Qflash successfully to upgrade BG96 modules to BG96MAR02A07M1G, I now find that attempting to reflash in Qflash gives the AT+QMBNCFG=“LIST” FAIL error
Strangely, after this subsequent attempt, I found that the same AT command stops working (only returns OK) in qnavigator as well.
2 of my 5 modules do not connect to the network, I noticed that at least one of them doesn’t have the required .mbn files loaded (until qflash prevented me from rechecking).
I want to use qflash to upload the new mbn files and update the firmware in the future.
I am also experiencing this same issue. I have opened a different forum question to help increase traction on this topic, and since I am using a different firmware version.
In Quectel_QFlash_User_Guide_V4.1 section 2.4 MBN Fucntion — I’m not clear on the “NOTE”. Am I supposed to create a directory called mbn and put all the .mbn files in it? Can you please clarify this part?
Via the AT serial port, when I run AT+QMBNCFG=“List”, it is currently empty. I’m suspecting this is FAILING because it is empty.
I also had a at+qmbncfg=“list” FAIL error updating the BG96 firmware. Even with Version 6.0 of QFlash.
After renaming the folder name in the FW update package from “update” to “mbn”, QFlash starts updating the modem but has error at+qmbncfg=“add”,“acdb.mbn” FAIL after reaching 100%.
