Help downgrade to Apple TV iOs 4.2.1

Any suggestion...? done the wrong thing with SesonPass, upgraded to 4.3 and lost XBMC... Thanks in advance

I hope that someone has an answer that i didn't found. Last friday my Apple TV 2 pops up with an update. I tought i disabled the update functionality via the proper way. After this XBMC does not seem to work anymore and crashes often with 720/1080 *.mkv files.
When i restored the device to factory defaults it seems to been installed with IOS 4.3 .

After research for hours i'm "brain fried". It seems that the only way to downgrade your Apple TV 2 device to 4.2.1 is with shsh blob file that is obtained via Tinyumbrella. The only file that i can obtain is the 4.3 because the other one is gone after the restore <=--stupid me .

There is an post for an tethered jailbreak for 4.3 that is positive. Only i found also an post of the development team that XBMC is not working on IOS 4.3 because the HW decoder uses changed API calls.

Can somebody help me with an solution to get XBMC working again. Hopefully ther is an way to downgrade this device without the shsh blobs?

Development Team: Do you think that XBMC will work in the near future on IOS 4.3 ?

Hopefully somebody has some answers;

With kind Regards,

if you can wait hold off until the jailbreak catches up, if not go with the tethered. Its your call, I suppose you could do some digging and see if you can turn up the progress.

Hudson the jailbreak is not the problem. I think that between now and a week there will be an untethered jailbreak. Only XBMC does not support IOS 4.3. I hope the development team will re-write there code.

If you saved your SHSH blobs with TinyUmbrella, then you can restore back to 4.2.1.

That's the big problem that i have Haskilla. I have only the shsh blobs of IOS 4.3 . So think I have to wait untill 4.3 is jailbroken tethered and XBMC will support 4.3 also.

Because without the blobs there is no way to go back I asume ?

The only bit that's not working is the h264 hardware decoding. the rest is fine and the team is working on the bits that are broken.

If you do not have your blobs, there is no going back. You're only option is to tether break on 4.3 and live with the issues until they are resolved.

Wish I would have saw this. >< Just bought a new Apple TV for the bedroom. Did a jailbreak and didn't realize it was doing the 4.3 update or that it didn't play well with XBMC. Eagerly awaiting a fix.

From the forums here it sounds like the XBMC devs are working on the hardware decode fix. With a little luck there'll be an untethered jailbreak and XBMC hardware decoding on iOS 4.3 /w before next weekend.

If Tinyumbrella can't get 4.2.1 shsh blobs then your stuck on 4.3...

But guys, this has nothing to do with XBMC and should be taken to a more appropriate forum...
