Same Issue
I have A developer account, so I updated to the 4.3 for my iPad 3G+WiFi, I played around with it, got bored of it and went to downgrade back to 4.2.1, I can't, I can downgrade to 3.2.2 and thats it, all my SHSH blobs are saved I tried recboot, and Tinyumbrella to get back to 4.2.1, it just puts me into the connect to iTunes loop, 3.2.2 works fine though and when I go to Cydia I see that me 4.2.1 is saved...anyone have any ideas?

I'm in the same position. I thought that you could downgrade since 4.2.1 is still technically signed by Apple. Guess not though. It's pretty buggy. Which is expected out of a first beta but I really thought I could go right back.
Whoops! Just gotta deal with it I guess.

And when they officially release 4.3, what will the steps be to downgrade it 4.2.1? Seriously. If you know that, it would help here.
But since you don't, and the beta nature of this release is irrelevant to the question I posed, why did you bother responding?
Nope, that doesn't work either.I've tried different versions of iTunes also and have my blobs saved for all the ios versions. Strange problem. I settled for going back to 3.2.1 jailbroken. No big deal and certainly not the end of the world. I was getting a little tired of the 4.2 tethered jailbreak anyway. They claimed to have had it jailbroken before it came out in Nov?? And here it is mid-January and still no untethered jailbreak. Sounds like Apple's tricks.
It's to do with the 3G baseband
The restore fails when it tries to downgrade the baseband which it can't.
Try this: restore to 4.2.1 then when it fails and leaves iPad in recovery, run the app 'recboot' to exit it out of recovery and it should be ok
Edit: just saw LudaKirs tried this already. I haven't tried myself yet as 4.3b1 is running well for ,e

FYI the untethered 4.2.1 iPad jailbreak has been out for weeks now with a redsn0w beta, as long as u have 4.2 beta shsh blobs on file. But that doesn't really help u now.
Remove sim card maybe?
Is this just happening with people who have the 3G, or both? and what about just removing the sim card before restoring...actually I don't think that would work, and im tired of restoring my ipad, so if someone else wants to give it A go, let me know...chances are it won't work though.

Hello,
same problem here.
I have an iPad and an iPhone 4.
Both are running iOS 4.3 beta1.
Only the iPad is registered in a Developer Account.
Now when I try to go back to 4.2.1 on my iPad it gets stuck at the recovery screen, because it could not downgrade the Baseband.
BUT, if I try to Downgrade my iPhone 4 from 4.3 Beta 1 to 4.2.1 - It works! And more, it also Downgrades the Baseband!!
I have tried all things mentioned above but nothing helped me with my iPad.
Sorry for my bad english!

Ok, here's some helpful advise, log on to your developer account and request some help, you are a developer, I'm sure
To communicate the issues of loading an unreleased update and asking for help
Just a thought. When you guys tried restoring to 4.2.1, did you remove the record for cydia signature server from your "hosts" file first?
i tried several times to retsore my ipad 4.3 to 4.2.1 with xcode. it stops saying can't change baseband back and failure 1015. i tried to restore to 3.2.2 that worked fine, but then i couldn't update to 4.2.1.
I wonder if we can remove the 4.2.1 baseband from the ipsw?

Might be worth a try, if pwnagetool worked with the iPad I expect you could just create a custom ipsw and restore to that?
