    there r no method of downgrading the phone. start-up will fail & simple JAF software can't even fix it. u'll need a real JAF box for that.

    from wat I know, when you upgrade a phone there are security settings that will be integrated to the phone that cant be erased but must be overwritten via upgrade.

    when you downgrade the phone, it will check for these settings & if it's invalid you will go through an "infinite loop" which will cause the phone to have failed start-up or it wont boot anymore (bricked).

    only solution to that problem is by sending it to your nearest Phone Care centre but attempting to downgrade your phone or flashing, w/e (by yourself) may void your warranty thus they won't help you in fixing an unbricked phone unless you pay an amount of money that is considered like buying a new phone.

    hope that explains everything

    if v brick our phone is it possible to revive the phone by again flashing with the upgraded firmware? And there is a better way for downgrading, go to nokia and tell them a thousand problems in the new firmware, and tell them u wanna downgrade. I'll do that if sir, steven releases n97 hs. And they 'll downgrade it without any charges at all.

    I successfully did it. Not with USB cables and Emulated JAF. You need a real unit with a FBUS cable/
