Downgrade 4.0.2 to 4.0.1

[speedy2056]

You don't need the SHSH blobs anymore!

Go to google, type in 'jailbreak 4.0.2' then hit the News tab and there is an article near the top on how to rollback 4.0.2 to 4.0.1 to JB.

4.0.2 CAN be downgraded without SHSH blobs.

Go to google, type in 'jailbreak 4.0.2' and hit the news tab at the top. there's an article about rolling back the firmware to 4.0.1 with a bit of code manipulation.

it's easy.

Did you read the guide? Tells you to use Blackra1n. That program hasn't been updated since 3.1.2. Geohot, guy made that hack, has step away from JB iphone now. Just because it's posted on internet doesn't mean it's true.

I don't really have to reply to you since I did in the other thread but...again...I USED the guide to rollback my phone, which is 3GS!

Try using the guide for yourself instead of jumping to false conclusions!

First sentence: "Ok guys let me clear this upfront. I haven?t tested this method yet, but by the looks of it, there is no reason why it shouldn?t work."

Update: "Ok guys, I know I took a little long to provide this update but this was because I was thoroughly testing this method to see if it really works. After trying it out on my iPhone 4, 3GS, iPod touch and iPad, I can confirm that this at least didn?t worked for me. But then again I got lots of messages from Twitter and email from users who said that they got it working on iPhone 3GS and all. But at least in all my tests, it didn?t work for me even on an iPhone 3GS."

Now, let me explain why people may luckily get it to work:
1) Notice step guide #8: "Add the 74.208.10.249 gs.apple.com line to the host file." That tricks Itunes into contacting Cydia server instead of Apple's servers. Do you know why? Hint: SHSH hashes.
2) Here's the important thing. Saurik, Cydia guy, clarifies it: It seems that more shsh are on file and even some of you that havent ever jailbroken and just got a new iphone may actually have an shsh on file. It?s definitely worth a try to set up Saurik?s signature server in your hosts file and try to restore that way. You may get lucky and get a downgrade even on a new device.

Once again, there is no magic / trick to downgrade without SHSH hashes saved for 3GS or IP4.

Read my posts correctly!

I said it "can" be used to rollback. This is not the same as saying that it's basically a "magic trick".
