First of all, to install custom firmware you need to install technological firmware somehow. You can't install it just by flashing, it will require flash code which cannot be obtained easily. To bypass flash code check, I made downgrading firmwares for several firmware versions. You need to install downgrading firmware for your current firmware version, which will downgrade to technological firmware, and from technological firmware you can install any firmware, including custom one.
What exact steps did you perform, what exact result did you get?
