Hello all,
i have a 3gs new boot rom running IOS 4.0 and its jailbroken. I jailbroke it with jailbreakme.com

i have my shsh blobs from cydia saved with tiny umbrella.

How can i upgrade to 4.1? im having issues with 4.0 and need to upgrade.. I still want to be jailbroken..
I used to jailbreak and unlock back when the 2g iphone came out. Apple has changes things so drastically now so now im lost.
Any help would be appreciated.
Thanks

Do you have your SHSHs for 3.1.x?

Do you have your SHSHs for 3.1.x?

no,just 4.0, 4.0.1, 4.0.2, and 4.1 via cydia
Id like to upgrade to 4.1 i just dont know how

Well then you can't upgrade to 4.1. I also forgot to ask what bootrom you had but since you can't downgrade to 3.1.x it doesn't matter anyway.

But yeah, if you have the 4.0.1 SHSHs, you can restore to a stock 4.0.1 ipsw and rejailbreak with jailbreakme.

You can also restore to 4.0. Your choice. Just get TinyUmbrella and pull those SHSHs in to your comp. Then run the TSS server. While that's running, shift+restore to a stock 4.0 or 4.0.1 ipsw.
