06-09-2013, 05:37 AM #1[HELP] Upgrade from iOS 4.1 to iOS 6.0.1 on iPhone 3GS [HELP]
Hi, i need some help with the upgrading of my iphone 3GS. it has already been jailbroken on iOS 4.1 and i want it to go to iOS 6.0.1. Anyone can show me some steps to do a successful upgrade without the usage of shsh blobs cause i have none for any version other than 4.1.
Thanks in advance,

*Unless you have an old bootrom device. If your phone's serial number starts within the range **920... to **945... you likely have an old bootrom device. Anything else, you likely have the new bootrom (and thus no downgrading without blobs).

I'm not sure you read the OP correctly, sorry.

to add what Orby stated, all iOS 6 SHSH blobs must also be "valid", i.e. must have been saved directly from Apple's server when it was still being signed, otherwise the blobs are pretty much worthless.
