iOS 4.3 and old bootrom 3GS

[JPSAL]

Does anybody know a way to jailbreak an old bootrom 3GS on 4.3? I tried using pwnagetool with the ramdisk fix and custom bundle but got error 1 while restoring. With redsn0w 0.9.6b8, it went through the whole process just to get stuck in the apple logo in some sort of weird DFU mode which was very difficult to get out of.

Any help would be appreciated.
Thanks

Unless you have shsh blob lower than IOS 4.3, you are not going to get untethered jailbreak at the moment
