Devo 7e not working was created by christx
When I switch on the power button nothing happens: nothing on the screen and no sound. I tested my batteries they are ok.
I Wonder if it's a common bug?
Any idea is welcome!

No, it's not common. It could be a firmware issue though.

Take out the battery for 5 minutes or more, then try turning it on in dfuse mode. That should work even if the firmware is busted. If that works, you can try power cycling to normal mode, or just re-install deviation. If you can't boot in dfuse mode, then it's liable to be a hardware issue of some sort.
Do not ask me questions via PM. Ask in the forums, where I'll answer if I can.

Hold the EXT button down while you turn the transmitter on.

Sounds like it's time to re-flash the bootloader ...

It should be possible to do without the stlink, but not sure how that's done with Devo.

Re-flashing brought mine back to life.

Could someone please tell me where to buy an St link. Do I need anything else (driver for example)?
Thank you!
