Cannot restore my iphone 3gs to 3.1.2...plzzzzzz help me

[futurerulz]

Dear Friends i really need your help as now i am in deep mess. my iphone crashed & now am not able to restore.

My Iphone Details :

Iphone 3GS (New Bootrom)
Firmware : 3.1.2
Baseband: 5.11.07
Jailbroken/Unlocked : Blackra1n
I don’t have the shsh file but have written down my ECID

Today i downloaded some keyboard from cydia & it asked me to reboot the device, which i did and since then i got stuck on to The Restore screen.

Methods Tried:

Redsnow 0.9.2 & 0.9.3: Gets stuck on the screen which says “downloading the jailbreak” & a something at the bottom keeps circling & later restarts n goes back to the Restore Screen.

Blackra1n : Image of that guy comes on the screen & stay there for few minutes & again restarts & goes back to the restore screen.

Pwntool 3.1.4 & 3.1.5 : after creating the custom firmware ask’s me to connect my device through USB, which i tried tried tried but it didn’t work..(I tried the DFU mode = Fail)

Itunes 9.0.2: Tried to restore by downloading the firmware from iclarified and tried doing it through the Shift Button method but i could not restore got an error msg “ iphone not eligible for this bundle” (tried to restore both in DFU mode & normal restore mode”).

Finally i tried the method of creating a localhost server thing (umbrella & tinytss) but didn’t succeed, as while restoring in itunes it gives me error msg (1601 (DFU Mode), 3001 (Normal Restore)). i get these error msges after “ verifying from apple server” but it takes about 3-4 mins before displaying the error msg.

I am really tensed , please please help me.

Thanks in advance

Without your SHSH saved, you cannot restore your phone to 3.1.2. Period. Because you have the new bootrom, your phone cannot even be restored to a custom firmware. Your only option is to upgrade to 3.1.3 official. Sorry.
