Hello, I'm french

I have a big problem with an ngage QD.

I have tried to flash it (with the ufs), but I thnik with the wrong flash files (I think there are specific flash files for UFS)

So I have begun flashing it, but when finished, the phone did not want to start.

So when now I connect it to the UFS box, there is nothing, the box don't recognize it at all.

Please help me, I have no sulutions I searched, but with no, results ...

Thanks in advance.

PS : excuse me for my bad english.
