Lumia 1020 :: Can't Work With Black Update

I've got a black 1020 (Carrier: Bouygues Telecom) that can't work with Black Update. When I update it, my phone breaks down. (When I run an app, there's the loading screen then back to the homescreen or the phones freezes).

I've try to hard reset, the problem is still there because when you hard reset, I think the update is still there. So i've try to reflash it with my carrier rom to have it like the first time i've had it in my hands, the phone works fine.But if I tried to update it to Black, the same problem shows again.
