Stuck in DFU mode

Hello,
I have got a problem with Deviation and my Devo 10.

Some models were corrupt and so I thought it would be a good idea to renew the Deviation 5.0.0
After copying the files to the Devo I had to format the drive on the devo, the space on the
radio couldn't be read neither from my computer, nor from my laptop.

So I formated and thought after that I can copy the files again. From there on the horror began.
After formating the first time, I had the format again and again the space on the devo couldn't be read.

To fix this problem I took the Dfuse tool and flashed the deviation5.0.0.dfu on the radio, and now he stays in
the DFU mode... After flashing the radio reboots for 1 second and switches to the DFU mode again. Clicking the leave
option in the DFuSe doesn't work either. The Radio has no USB mode. After flashing, the Power on button + ENT has the same effect
as only Power on and the same as PowerOn + EXT, namely "Programm Update ....". He is stucked in the DFU...

Is there anything I can do? I tried Walkera Firmware and other Deviation versions, every time he stucks in the DFU mode.

I also tried other Version like Dfuse 1.7 and 2.31 and other Deviation 4.0.1. Battery was unplugged for 24 hours, same problem.

Thanks

yes 100% sure..

no.. it's the right firmware...

I saw other guys had exactly that problem too with the devo 10... They took another dfuse tool and another firmware and it worked for them.
