When I finish all the JB steps the ATV2 remains with a blinking light - the TV cannot get a signal from the ATV2. It looks like it ends stuck in DFU mode. The last few times I have started having difficulty getting it into DFU - where previously it was straightforward.
iTunes has usually crashed out with 2005/2009 and 1904 errors during the final stages of the JB.
After each fail I have attempted a tethered boot just in case - with no success.
I have been able to get the software back to a functioning 5.0 (itunes still crashes out but the ATV2 boots okay) on a number of occasions.
I have a USB booster cable connecting my PC upstairs and ATV2 in lounge as I have no laptop. I’m ruling this out as an issue becuase I can still get 5.0 back on the box if the JB fails in some way, and DFU signals interact with seasonpass.
Thanks CYBERxNUKE - however this is exactly what I have been doing (and I have also tried briefly removing and reinserting the USB between JB and boot tether steps as stated in seasonpass instructions). No joy - I get a blank screen with no source and a flashing white light everytime…
I have been very careful to follow the exact steps for the JB with seasonpass.
I am having the exact same problem. When it goes into itunes to update the version some error box flashes on the screen but it is very small and is only on the screen for half a second. Any help would be appreciated.
I had a similar situation with my atv stuck in DFU mode and everytime i flashed my atv it would give me a blank screen and Also errors.
The only way for me was to first restore with Original 5.0 (iOS 5.1 - 9B179b) then unplug and test on TV. it should be booting and working again.
Now restore again with the SeasonPass JailBreak File! Then unplug USB. Then close iTunes and reconnect USB and Power to ATV and do a tethered Boot with seasonPass. Do Not disconnect Power Cable when Tethered Boot is finished. Just Disconnect Usb & plugin HDMI.
Thanks for everyone’s help - however still no joy.
As i do get errors (1600) - even after a normal restore in itunes, i’m thinking that it must be the USB cable.
As it stands my ATV2 is always left in a DFU like state after a JB - even after a tethered boot.
I’ve tried iREB to try and ‘break’ a DFU loop - however iREB states that this does not work for tethered boots.
Annoyingly my ATV2 does not now go easily into DFU mode (without power cable) - instead it flashes twice then stops flashing, flashes twice then stops flashing, etc. rather than the very rapid flashing. It appears to now only go into DFU if the power cable is plugged in - not sure if this is a big issue or not.
Next step? Get a laptop from somewhere and start again…
