Do you have *exactly* the same problem as the OP?
If so, and you've followed the instructions given by Grayson, Marilyn and Leigh, what exactly happened? You need to provide some details.

i followed everything, but still.....
to no avail.

maybe this is because apple stops signing 4.3.4.
i'll just wait for an update of the tiny umbrella.
goodbye jailbreak for now and hello boring environment.
sigh....

I have exactly the same problem, in the same situation (same ****!)...

Messed around with Cydia apps and screwed the JB iPad 2 (3G + Wifi)....

Had to restore to factory settings and that meant upgraded to 4.3.5. Noted that however the baseband is the same as 4.3.3's...?

Tried using Tinyumbrella and did a firmware restore to 4.3.3 but could not kick it out of the recovery loop.

Did the DFU thing to fix recovery but still of no use.

Guess I would just have to stay with 4.3.5 for now. Gonna miss Cydia and all the other good stuff!

NB: should anyone who had been successful in downgrading 4.3.5 to 4.3.3 (iPad 2 3G+wifi), please do share. Appreciate!

Yeah, I have the same things too... Ipad 2 (3g+WiFi). There is no solution to kick out from recovery mode. Tried it many times, with Tinyumbrella 5.00.07, or with manually apple readressing in hosts file. With fixrecovery43 also.
I can try once more with log in every details about it - if somebody is interested in...

Tried once more. The same effect: 1013 error and unrecoverable iTunes+USB loop.

Hi,

Can't help to wonder on what are the things that you can do to "mess up the JB"? Is this the only reason we might need to downgrade?

Still thinkin on whether i should JB or not. Using ipad2 3G+wifi on 4.3.3

sorry.. newbie here

Also having the same issue, process was the following:

Running 4.3.3
JB via jailbreakme.com
Screwed up my ipad by modifying it too much
Ran TU to backup SHSH
Attempted to restore 4.3.3 with 1013 errors
Managed to restore 4.3.3 but stuck in recovery mode
Tried most tricks via Google such as fixrecovery, using alternative iphone apps to reset env. variables
Restored to 4.3.5
Tried to downgrade to 4.3.3 but got stuck in recovery mode again


Running out of ideas

iPad 2 3g GSM (16gb)

This is the FAQ from the DevTeam:

Q: Will I permanently lose the jailbreak if I need to restore my device?
A: For all except the iPad2, saving your SHSH blobs should let you always restore your device to iOS versions where this jailbreak works. The iPad2 is a little more complicated. If you have a wifi-only iPad2 and saved SHSH blobs, you’re in good shape. But if you have the GSM or CDMA iPad2, you won’t be able to restore to 4.3.3 or lower once Apple stops signing its baseband. There are a few ideas that might work to get around this limitation, but for now it’s best to assume there’s no going back to 4.3.3 once 4.3.4 is out for iPad2 GSM or CDMA owners.

So, currently Apple has stopped signing the 4.3.3 baseband, you will not be able to restore to 4.3.3 by any way. Maybe comex or others can find new solution soon but not now.

No, that's wrong, Apple didn't update the baseband for the iPad 2 neither in 4.3.4 nor in 4.3.5, so of course they are still signing it. That's definitely not the issue here.
