Dear @stich86
I have sent it to you via Message, please check.

i’ve tried but gives me error:

echo -e ‘AT+QADBKEY=“Y5zU.E9QRH702z3”\r\n’ > /dev/ttyUSB3 ; cat /dev/ttyUSB3

ERROR

Use a terminal app, not echo.

I don’t have it :frowning:
no way using echo?

Looks like flashing went wrong, now I’ve the module in bootloop, and running QFirehouse gives me this error:

Any way to recovery? I don’t have a boot point (EDL exposed… or not known on this board)

Dear @stich86
Did you check /dev/ttyUSB*？Before upgrade, did the module worked fine?
Is it possible to use -P to configure specified port for upgrading?

10

yes module was working, now it’s in bootloop…
each time it start then reboot itself

11

Dear @stich86
It is strange, module in dump mode. which command did you use to upgrade? ./Qfirehose -f and others?

12

yes ./Qfirehose -f /path/to/firmware

flash went fine each time, but the the module reboot, stay for few seconds on “fastboot” then back to EDL.
No the problem on the last flash is that module seems to go in “dump mode” (in a loop) and no way to put it back in EDL mode (and I don’t have any boot point avaliable).

Any suggestion?

Thanks

Dear @stich86
Please check if you can pulling up USB_boot to VDD_EXT.
