Unbricking a VOXL 2 - Pass but no ADB?

@czarsimon Can you confirm that you are flashing the correct image for your board? M0054-1 (QRB) vs M0054-2 (QSM)?

Hi @tom I can confirm the VOXL 2s I have are QRB5165M.

tom

@czarsimon And after the QDL process are you turning the switch back off and power cycling the board?

czarsimon

@tom Yes correct

tom

@czarsimon Does the board enumerate via lsusb? If so, what do you see?

czarsimon

@tom With the QDL switch in the ON position:
Bus 002 Device 010: ID 05c6:9008 Qualcomm, Inc QUSB_BULK_CID:0412_SN:68E7EC23
With the QDL switch in the OFF position:
Bus 002 Device 010: ID 18d1:d00d Google Inc. Android Serial: f75e1ba6

@czarsimon Okay so with the switch off it is booting to fastboot, are you able to install the SDK at this point?

@tom No, the device is not found in fastboot mode.

@czarsimon I can see by the output that the device is in fastboot mode, but it is still possible that fastboot itself isn't picking it up if the permissions on your machine aren't correct. If you try flashing the board with sudo does it detect the device?
