YES! Solution to downgrade iOS 4.3b3 to 4.2.1

[torarne70]

I found a solution to downgrade the iOS on my iPad from 4.3b3 to 4.2.1*I had IOS 4.3b3 on it. what I did was to upgrade to 4.2.1. Upgrade with shift+upgrade and used orginal iOS 4.2.1. You wil get an error in iTunes ignore it. Use tinyumbrella to kick it out of recovery it will start normal and ask for unlock kode ignore it. then i run Greenpos0n RC5_2. and you have IPad on iOS 4.2.1 jailbreaked


Update!

Just do a iTunes shift+restore and select iOS 4.2.1. you wil get error 1015 ignore it. just run Grenposi0n RC5 and you ar on 4.2.1 jailbreaked YES!!

Update

You don't need Cydia shsh blobs for this on to work, like the sticky thread needs. In iOS 4.2.1 and 4.3 beta's Appel has baseband check that make it impossible to use Tinyumbrella or Cydia to downgrade.

Update! Just do a iTunes shift restore with iOS 4.2.1. you wil get error 1015 ignore it. just run Grenposi0n RC5 and you ar on 4.2.1 jailbreaked YES!!

Hey I'm having trouble with this, whenever I try to do the shift restore and select 4.2.1 I just get a message that says device not eligible, no error message or anything then it just kicks me back to the main itunes restore area.

I'm on the same boat as you.
I bought a second-hand iPad with 4.3 already in there.
Any way to downgrade to 4.2.1?
Will this downgrade method work?

Try jail break ipad 4.3 first use snowbreeze . and then open cydia , see in top, shsh 4.3 or shsh 4.2.1,4.3 . , if u just have shsh 4.2.1,4.3 , thats ur ipad 100% will succes downgrade

You can only downgrade your iPad if you have SHSH blobs saved for the version of IOS you want to go to. Blobs are unique to your device and cannot be spoofed.
Since your units are factory fresh with 4.3 installed there will be no chance for you to downgrade as things stand. If however they were refurb units and somebody saved SHSH's before for the device, then you would be able to downgrade.
An easier way to check than what Chiangx suggested is to download tinyumbrella (google it) and this will tell you what SHSH's you have without having to jailbreak first. Most likely it will be 4.3. though. Sorry.

Hope that helps.
