    Downgrading is risky there's a big chance you will brick your phone as far as i know.
    Some posters have claimed to have done it without JAF box.

    Why don't you like v50 its great.

    brick mean that you cannot turn on your phone (maybe)
    you can use custom firmware... most of cfw is stable n fast..

    If i have Jaf Box can i downgrade?? I mean can i go to NCC and ask them to downgrade my phone to V40? I miss my V40 speed.. Even with custom firmware cant have free Ram as much as V40 and V50 feels slower than V40..
