Unbricking

spiff

I received a new Sentinel drone but haven't been able to connect from my (Ubuntu 24) machine via adb, and lsusb also doesn't show the device. Per the unbricking guide I opened the flight lid, flipped SW2, and attempted to use the QDL tool to flash the device, but I'm getting an error on the first "Provision" step -- the frontend throws this error:

Provisioning UFS...
Failed to provision UFS

and the terminal shows:

[12/Nov/2024 19:30:07] "GET /get-flat-builds/ HTTP/1.1" 200 28
Internal Server Error: /provision-ufs/
[12/Nov/2024 19:30:08] "POST /provision-ufs/ HTTP/1.1" 500 39

@spiff If lsusb isn't showing the device it's likely either a cable or power issue and not a bricked drone. Are you running Ubuntu 24 natively or are you using a virtual machine?

spiff

I'm running Ubuntu natively on my laptop. I've tried a couple different USB cables, but I will try another. The drone is powered by the AC adapter.

@spiff We've seen some weird cases where ADB has issues when using USB-C to USB-C cables. If that is the case people have had success using a USB-C dock with USB-A ports

spiff

@tom I've tried a few cables, all USB-C to USB-A, but I'm getting the same provisioning error. Does the QDL tool have any other logs I can look at to determine the issue?

tom

@spiff Does it not show up with lsusb regardless of whether the switch is on or not?

If it's not being in lsusb then QDL isn't going to be able to see it so won't be providing an data

spiff

@tom Ah, I do see this! Maybe there was a cable issue:

Bus 001 Device 034: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

This is with the switch ON, though I'm still getting the provisioning error.

@spiff And if you turn it off and power cycle does it show up with lsusb?
