hello 

I accidentally adb pushed a file to /bin/bash replacing the file, now I am unable to use the bash shell. is there any way to get the ./bash file back? 

drone modal: M500 
hardware: Voxl-flight 
voxl-SDK-ver: 0.9

hopefully that is enough information for assistance

@QuiroJ6427 I'd recommend just downloading the latest SDK from downloads.modalai.com and installing it. The latest for M500 should be SDK 1.2.0. 

0.9 is quite old at this point so this will be a nice upgrade regardless
