    thanks for the reply... no i didnt stitch the shsh blobs to the custom ipsw, should i use shsh blobs when upgrading from ios 5 to ios 6? i thought shsh was for downgrading and yea i saved my shsh blobs with tiny umbrella. what should i do?

    If you have a 3Gs with an OLD bootrom, you can just create a custom firmware from sn0wbreeze without stitching the blobs, and you can restore to any ioS 6.

    If you have a new bootrom, then its more complicated because even if you have shsh blobs saved, you must have saved them "locally" to your hard drive either from redsn0w or ifaith when Apple was still signing them.

    If you saved your shsh blobs from tinyumbrella, then they are worthless and cannot be used to restore back to any iOS 6.

    To check whether you have old or new bootrom, follow the instructions from this site:
    How to Check iPhone 3GS New Bootrom / Old Bootrom (iBoot) Version | Redmond Pie

    Then download ifaith program and verify the blobs to see if they are "valid".

    Then answer 2 questions and we can further assist you:

    1. Is it the OLD bootrom or new?

    2. Are the blobs valid?

    Just tell sn0wbreeze that you have an old-bootrom 3GS (I'd use Expert Mode but Simple should work as well) when you select your 6.1.2 (or .3... or whatever IPSW you would like--I'd recommend 6.1.2) IPSW. Sn0wbreeze should then build you a custom IPSW (which will preserve your baseband), enter Pwned DFU once the IPSW has been built, restore it via iTunes, and you're off to the races!

    since its an old bootrom 3gs, that means i can put it in pwnd dfu mode and downgrade to any os when im ready right?
