3GS Mis Happ!! need urgent guidence from the geniusS!!

[pranav]

I have a 3GS 16GB Black - V3.1.2 / BB 5.11.7
It had an At&t lock. I'll narate the event ive faced chronically.

1) I jailbroke via blackRa1n & unlocked with snow.

2) Worked well for a day. But the next morning i wasn't able to charge my phone via usb. So i reboted & tethered the phone a couple of times. BUT!! it suddenly started getting stuck on GeoHotz picture & if rebooted it starts on DFU mode.

3) I tried restoring 3.1.2 via 74.208.10.249 gs.apple.com. (cydia shsh)
It displayed error in the verifying via apple stage & din work.

4) loosing my patience i started redsnow 0.9.4 with the restore pack of 3.1.2 what became worst is my screen displays nothing. (completely blank). It is thus detected in my itunes & displays restore to 3.1.3 option.

Like everyone else I need 3.1.2 jailbreaked on my phone.
Im really nervous & worried.
Geniune helps & suggestions would be immensly appreciated.
I am waiting for some genius's to reply!! PLS HELP!!
