Help - Upgraded iphone 4 to 4.0.2, lost unlock.

[joepic]

I upgraded my iphone 4 to 4.0.2, and now I lost my JB and unlock.

Can someone help me think of any ideas on how to downgrade it back to 4.0.1?

Is there any promising news to when a JB solution will be released for 4.0.2?

Am I screwed? Please help.

If you haven't saved your 4.0.1 SHSH blobs, yes you're screwed.

I'm pretty sure I didn't. Will I just have to wait for the dev team?

Do you know if you stored your SHSH blobs? Try searching before posting?

Download tinyumbrella to see if cydia stored your blobs.

Pretty much, need to wait for a new JB for 4.0.2

Just as side not, if you are Jailbroken/Unlock, never upgrade using iTunes. Wait, read forums and the dev teams website for instructions.

Thanks.

Are there any speculations as to when a new JB will be released for 4.0.2?

Return the phone and buy a new one with 4.0.1

More then likely not. I think they will wait for 4.1.

There won't be a jailbreak for 4.0.2. It'd be a waste of an exploit just for people who stupidly upgraded without an SHSH on file. You'll have to wait for 4.1

And then I also forgot to mention there might not be a unlock available right away, if ever. Never upgrade.

Again did you query cydia to see if your SHSH was saved?

I'm sure you on about a iphone 4 or 3gs but if not and your talking about a 3g or 3gs (non MC model) then you can use redsn0w to jailbreak 4.0.2

It's an iPhone 4.

Return the phone and buy a new one with 4.0.1

if you go through ebay or craigslist your losses will be minimal, perhaps even making a profit on the transaction.

Since Apple is still signing 4.0.1, shouldn't I be able to just downgrade?

Yes, if Apple is still signing 4.0.1, then you should be able to downgrade. Please make sure you do a backup 1st. Also make sure you download the 4.0.1 ipsw file and use shift Restore option to restore it.
And last don't forget to save you SHSH blobs once you restore it to 4.0.1 using Tiny Umbrella. You may be still able to save your SHSH now also, since i don't have a iPhone4 not 100% sure about it. Just did for 3G yesterday for my buddy but the 3g was restored to 3.1.3.

When I try to shift - restore, it gives me an error saying "iphone could not be restored because the firmware file is not compatible"

should i downgrade itunes?

Try using this IPSW

If it won't work, the perhaps Apple has quit signing 4.0.1 firmware.

Looks like you don't have the correct ipsw file.
Try downloading from the below link.

Use Tiny Umbrella and click option on right side "Kick Device out of recovery mode" and it will reboot fine..

 

[joepic]

however, i can't get off the slide for emergency screen...
