(it don't boot by regular methods....plus i have tried all home+sleep button combinations ) ...rest its all black and i am losing hope

Have you tried using Tiny Umbrella to kick it out of recovery/dfu?

Perhaps you could try a program called RecBoot (if you're on a mac) don't have a link, but some googling should do the trick.

I think your 6.15 baseband is the problem here: you can't install standard firmware releases once you've got that on

I don't think there is currently a way to downgrade your baseband from 6.15 so you'll have to use custom restore images until one does appear

Have you tried actually "rebooting the iPhone"? Such as holding the switch and home button together until it will reboot and load the current iOS available. It should then mention that you are in recovery mode. Once recciving iOS 5 beta, I suggest making a custom firmware with it, because you baseband is what is mainly screwing up the installation. Anyways, I believe a custom firmware should work as others have mentioned.
