[gvk5904]

Hi

I had a Apple Iphone 3GS on AT&T.
I unlocked and Jail broke it using Blackra1n and everything working fine.

Settings-->Reset-->Erase all media

Now iphone restarted with a Blank screen(black) with apple logo and hanged by displaying the Blankscreen with Logo

Please advise how to resolve this

Thanks in advance

Why 2 threads at one time ?

You erased the software required for the phone to boot. If you have 3.1.2 SHSH saved you can restore to 3.1.2.

You need to get the phone in DFU mode (see my sig).

Please not that unless you have your 3.1.2 SHSH on file in Cydia or saved locally using Umbrella, you will only be able to restore to 3.1.3 official and will lose your ability to jailbreak for the foreseeable future. Sorry.
