Hi guys, 
My VOXL has been brick.

But I don't have debug module.

Is there any method to unbrick without debug module?

especially, I have PDDL module and checked it has emergency switch to enter factory mode.

Can I recover my VOXL in emergency mode?

Thanks,

Hi @shlee853 ,

Unfortunately that switch on the Microhard modem is a lower level factory emergency boot switch only.  It can be used in conjunction with a factory level "QFIL" application that we can't distribute.  When enabled, the device boots up into a special mode, but fastboot can't see it in this mode.

What will likely be needed is the Debug module with the "fastboot" switch.

Question: have you attempted to boot up with/without the Modem attached?  Trying to eliminate possible issues.

Thanks!

Also, if cameras get plugged in backwards (I've done this myself too many times....) then the VOXL might not boot up.

@modaltb thanks for your reply. 
I have a VOXL flight deck and I didn’t change camera installation on it.

When I stopped updating system software then my VOXL has been brick.

Ok I’ll prepare debug board to treat fast boot.

Thanks buddy
