Because i do not speak English I use google translation, so immediately I'm really sorry for the mistakes.
To summarize, I tried to root my phone, as this tutorial site, but here, now it is flashed (so it only make white screen / black) but no way to use "run me", it's "waiting for device" and the driver tries to move into the vacuum. I tried EVERYTHING (updated every imaginable drivers).
I want to know how to go back and recover the use of my phone.
Again sorry for the mistakes and advance thank you for your help, that's my last option before a seizure ...
