In UMTS & LTE EVB Kit with BG96:
I was following development steps modifying a GPS example, compiling code and upload with QEFS Explorer,
I reset by button and platform hang up, like going sleep, and now it’s not possible flash again, it only appears 1 USB port (DM port) but it’s not possible to flash again, QEFS explorer hangs and exit.
I have tried again long reset, three times reset and I with in device manager likes appear 3 ports and inmediately disappear and only one remains (DM)
Any trick to reset completely flash or access by DM port? I’m desperate.
if you have problems with reflashing & DM port … the small board with module have control point USB BOOT
connect this point with VDD_EX ( 1.8v ) with 1k resistor, power ON and select new com port … reflash
HI again Stephen,
I don’t have the version of the firmware to reburn, I don’t see it included in the QflashV_4.15 package for BG96?
Thanks, but now the main problem is obtain the firmware and try reburn. I 'm waiting to Quectel support contact me 3 days ago

I have localized USB_Boot_Pin if it’s necessary
