is it possible right now to update to 5.0.1 while keeping the baseband from 5.0?

my 4S is still on 5.0. I read that I should update to 5.0.1 before 5.1 comes out and kills the corona jailbreak. Is it possible to keep the older baseband for future unlocking purposes?

thanks

Impossible. How can you do that if there isn't any tool available or work on 4S. However, I heard that you can use tiny umbrella to save shsh blob for it and if that is true. You should do that now.

I thought you can just create a custom Ipsw that preserves the old
baseband during the update, no?

Yes, but not for the A5 devices. They have cracked these yet and therefore, there isn't any tool can do this yet.

NO!
but from what i've read, using OTA update would give you a "lower" baseband then using iTunes. i'm not sure if that matters much.

basebase is unpreservabable using tinyUmbrella at this point; just ios version.

Do you have the latest version of TU? Latest version can save SHSH blobs for 4S.

 

[maximus96]

It should be the latest, I just downloaded it from their website

It doesn't make a difference. Even with SHSH saved, you cannot downgrade from 5.0.1 to 5.0.

Yes, but OP wants 5.0.1 Blobs so if iPhone hackers find an exploit, he will have blobs to go to 5.0.1 when apple releases 5.1 update. Reread OP's first post.

Ah I was under the assumption that wasn't possible either. Alright then!

It's not possible yet, until they find an exploit. But its better to keep SHSH blobs just incase, doesn't hurt.

I can confirm that doing an update OTA does update the baseband as I just watched a friend get on 5.0.1 to be ready for the JB.

Nope.
