Downgrade 4S iPad2/3 with new Redsn0w

Great news!:D But I think I'm going to hold off until the next update. A lot of people are having various problems and posting them in the comments on the dev blog. I'm in the middle of exams and I can't afford to screw up my phone.
 
Can someone post up directions on how to do this? I don't have any "blobs" saved since my replaced 4S is still on 5.0?

How do I go about doing this? I'm assuming I need to upgrade to 5.1.1 then downgrade again to 5.0.1? If so, how do I downgrade? Sorry fellas, I'm still new to the iOS side of things. :confused:

*UPDATE*

I checked Cydia and it says my SHSH Blob is 5.1? How can this be? I also ran 5.0.1 JB a few months before upgrading to 5.1 - I then exchanged my 4S for a new one which came with 5.0 which I'm also running JB at the moment. Overall I'm confused on how Cydia says 5.1 instead of 5.0.1?

Whoa.

So can I downgrade all the way back to 5.0 then on my iPhone 4S now?

I made "clean" blobs of 5.0 and 5.0.1 (no jailbreak installed).

Then I can install the Absinthe JB again?

Is that correct?


EDIT - nevermind - I only have two blobs of 5.0.1 - the #5 and the #6 updates.

Still, this is fascinating. Downgrading without a bootrom exploit!
 
Question : I ran cydia on iPhone 4S (running 5.0.1) for several months, do you guys think it saved my blobs? I'm actually quite positive that I hit the Blobs button anyway.

Also, is there like a tutorial on this? I'm running 5.1 at the moment.

Thanks in advance.

Onyl one way to find out - run the new redsnow program. If it finds the blobs, then you're good to go.

I used TinyUmbrella and just saved them to my PC.

WHatever you do, DO NOT TRY to use this this tool with your phone. Your blobs from your first phone are useless now, they will not work on your replacement. If Cydia says you only have 5.1 blobs then you cannot restore to any firmware at the moment other than 5.1.1. which has NO jailbreak. When the iPhone 4S was released there was no reason to save SHSH Blobs for it because they were useless hence Cydia didn't cache the 5.0 A5 blobs. Later on Saurik changed this so that 5.0.1 blobs were saved but if you don't have those blobs saved for the phone you are currently using then you cannot downgrade OR upgrade in your instance to that firmware. You need to be very careful until the next jailbreak is released because if you get stuck in restore loop because of a bad tweak or package then your phone is going to be stuck at 5.1.1 with no jailbreak.
 
As i read the tweet from pod2g, they haven't closed the loop on 5.1.1, my guess is that it will work on 5.1.1

Thanks for the heads up my man! That clears it up :D
 
this is awesome. just downgraded my 4S. first time i had that gui bug but second time worked like a charm :) now running absinthe
 
I'm staying on 5.1 for now.

Hoping for a 5.1 (or 5.1.1) JB so I can keep the battery-saving updates Apple made in the last update.

5.0.1 ate my battery alive.

But it's nice to know I can go back to 5.0.1 and use Absinthe whenever I feel like it to JB again.

Thanks Dev-Team! You guys rock.
 
has anyone done it yet?

i would like to start fresh again with the absinthe jb.

SHSH blobs are device-specific. You can't pull the blobs off of one iPhone 4S and then restore them with a DIFFERENT iPhone 4S. It has to be the exact same phone.

I just tried and nearly had a heart attack thinking I screwed something up. It kept saying my shsh blobs aren't compatible with the ipsw build. I tried using the shsh on cydia but it said they can't be located. Not sure what I could be doing wrong. My phone got stuck on the connect to itunes logo. I used redsn0w to verify my blobs and it said they were valid and apticket present.

Hmmm...I have a 4s on 5.0 that needs restored. It is a verizon that was unlocked with a CDMA ultra S Gevey. This said it updates to the latest baseband, I wonder if the CDMA gevey unlock is compatible with the latest baseband, as I know it is for GSM phones.

Do you have your shsh blobs for 5.0.1? You can't restore to 5.0.
 
I'm so excited! And glad I saved my blobs. I had to restore a while ago and it has been sad.

Really? I havent tried but this was copied from the one link. The only IOS that my phone has ever been on was 5.0, so I only have the blobs saved from that.

At this point however, it’s worth noting that the iPhone 4S can be downgraded all the way to iOS 5.0 from 5.1.1, same goes for the iPad 2,

Maybe TinyUmbrella saved 5.0 blobs but Cydia didn't. My bad

Do we have to be on 5.1.1 then restore back? Or can I do like rick wants and do it while on 5.0.1?
 
Make sure you have the 9A405 blobs.

Edit: Just reporting that the downgrade worked perfectly for me. No problems.
