iPad Downgrading iPad 1 from 5.1.1 to 4.3.X, is it possible?

[Kenrae]

Hello everybody, and thanks in advance.

I need to test an application I'm developing in an iOS 4 (damn customers...), but I've only had iOS5 and iOS6 devices for some time. I've tried downgrading an iPad 1 from 5.1.1 to 4.3.3 and 4.3.5 to no avail, I've followed many tutorials using a combination of TinyUmbrella, Bluefreeze, iFaith and Redsn0w.

I don't mind if it's tethered and I don't have any data or apps that need restoring, this device is only used for testing. I don't have any SHSH blobs.

Any help?

You need to make sure you have your 4.X shsh's.

If you have then you then need to stitch them to a firmware file & restore using tiny umbrella (i think)

Follow this link for a rough guide, but google is your friend

Errr... as I've said, I don't have any shsh's...

can't be done without shsh blobs saved.

You will need to find another device that has iOS 4 installed or has shshs for ios 4.x
