i need help

i have JB iphone 4 iOS 5.0.1 bb 1.59.00 unlocked via ultrasn0w

today i got ma phone bricked while installing Siri Original from russian repo, now m going to restore it with custom ipsw c'z if i didn't stitch my blob file , i will .definitely loose my baseband 1.59.00 and so my unlock (unltrasn0w)

i want to install iOS 5.1.1, but as i try to stitch my blob file with original 5.1.1 firmware, it says " the blob doesn't appear to match with this IPSW build "

is there a way to install 5.1.1 on my phone ?
or i have to install same 5.0.1 again ?

At the iPhone hacks section.
You cant stitch a 5.0.1 blob to a 5.1.1 ipsw.
That's why it's telling you it doesn't match.
5.1.1 is the current firmware signed so you don't need to stitch anything. Just put your iPhone in pwned dfu and select the custom 5.1.1 to restore to.

You can just make a custom ipsw with no BB, and install it. You do not need to stich SHSHs as apple is still signing 5.1.1.

If you insist, you can of course get the 5.1.1 SHSHs with TinyUmbrella, iFaith or redsn0w - and most likely Cydia has them as well. But you don't need them (until Apple releases the next version).

yop, no need for SHSH to be stitched for 5.1.1, however to remain on the 1.59.00 BB you need a custom IPSW without the BB, redsn0w or sn0wbreeze can make it.
