Voxl 2 is bricked and not responding to adb shell or wifi.
We tried forcing it into fastboot but  we couldn't see change.
Tried the qdl method for unbricking by following the guide and got the following response on terminal
"""
<response value="ACK" rawmode="false" /></data>
partition 1 is now bootable
FIREHOSE WRITE: <?xml version="1.0"?>
<data><power value="reset"/></data>

FIREHOSE READ: <?xml version="1.0" encoding="UTF-8" ?>
<data>
<log value="INFO: Calling handler for power" /></data>
LOG: INFO: Calling handler for power
FIREHOSE READ: <?xml version="1.0" encoding="UTF-8" ?>
<data>
<response value="ACK" rawmode="false" /></data>
""""
This was the expected output shown on the page as well.
When we switch sw2 switch off though, adb shell still isnt loading
When the sw2 switch is on voxl 2 is recognised over usb in lsusb command but when it is off it isnt being recognised over lsusb either

@tom @Eric-Katzfey @modaltb  Could you look into?

@Prawin-Sankar-T-A What OS is your host machine running? Sometimes QDL won't start up the first time and requires power cycling the board and retrying a couple times

@tom My host machine is using Ubuntu 20.04. Based on documentation provided [here](https://docs.modalai.com/voxl2-unbricking/#usage), I have tried this method a couple of times.

@Prawin-Sankar It may be worth submitting an RMA at this point: https://www.modalai.com/pages/rma

@tom Are'nt there any other debugging methods we could try out?

@Prawin-Sankar QDL is the lowest level flashing method we can share publicly so if that's not working there's not much we can do.
