I was trying to upgrade to newer version of VOXL SDK. The installation abruptly stopped due to my system being switched off. Now, adb shell is not working.

@riteshsharma you will need to try to recover using the unbrick procedure https://docs.modalai.com/voxl2-unbricking/

@Moderator Hi, I have VOXL2 where SW2 switch is set to ON position and is no way I can switch On/Off for unbricking.

since it is set to On position, I tried following command from the instruction at https://docs.modalai.com/voxl2-unbricking/ , but it keeps waiting for EDL device.

@riteshsharma In that picture it appears to be in the "off" position. Why do you say that you have no way to switch it?

@tom Thanks. It appears that the switch is too tiny. I think I was able to make it work.

Hi @riteshsharma 
We usually recommend a small screwdriver (flat edge) or tweezers to actuate those small switches.
For the FASTBOOT switch, you need to use something less likely to break the top plastic, so the back end of a qtip or a pencil is good for that one.
