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.

@Gary-Holmgren If you try to run the install.sh script when the board is booting to fastboot does it make any progress? You'll have to make sure you select the correct board type (qrb5165 vs qsm8250) otherwise you may enter a bricked state. Checkout the different between M0054-1 and M0054-2 here: https://docs.modalai.com/m0054-versions/#m0054-1-and-m0054-2

@tom Hi thanks for the suggestion. Although I’m a bit confused what you mean by selecting board type? I downloaded the latest system image from miscellaneous which seems to be compatible with my M0054-1 board. I don’t see any option to select the board specifically in any of the setup for QDL

@Gary-Holmgren Sorry I was referring to flashing the board through `fastboot`, if it is booting into fastboot I would try using that as opposed to using QDL. So would just be downloading the latest SDK from downloads.modalai.com and flashing using `install.sh`

@tom This was indeed the solution, retried the SDK flash with normal fastboot and it worked. Thankyou!
