Hi, I believe something went wrong when trying to upgrade a new SDK on voxl2. I suddenly cannot adb shell or unbrick.

I have tried every type of USB cable including ones that have worked for flashing this voxl2 before. 

when using lsusb with the switch turned off on voxl it shows up as
```
Bus 003 Device 007: ID 18d1:d00d Google Inc. Xiaomi Mi/Redmi 2 (fastboot)
```
When tunring sw2 to on it shows up as 
```
Bus 003 Device 008: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)
```
So I am lost at what to do as I followed the unbricking procedure exactly in order and keep getting "Provisioning UFS...
Failed to provision UFS"

```
Internal Server Error: /provision-ufs/
[13/Dec/2024 17:50:58] "POST /provision-ufs/ HTTP/1.1" 500 39
```
I am not quite sure what to do and would appreciate any help getting my voxl2 back up and running.
