hi guys, I tried to save the SHSH of my ipad2 5.0.1 using TinyUmbrella v5.10.04 but it failed

01/04/2012 23:49:21.047 For version [iPad2WIFI 5.0.1 (9A405)] - This device isn't eligible for the requested build.  01/04/2012 23:49:21.052 CYDIA DOES NOT HAVE YOUR SHSH FOR iPad2WIFI 5.0.1 (9A405) THERE IS NO WAY FOR YOU TO GET THEM. SORRY. YOU ARE JUST TOO LATE.

after upgraded to 5.0.1 my ipad2 still support multigesture but eventually at iPhone4-5.0.1 is gone..

So for now its not possible for A5 devices (iPad 2and iPhone 4s) to downgrade back to IOS 5.x.x even if SHSH are saved via Tiny

This will be only possible once a bootrom exploit is out for A5 devices ( i.e Exploit like limera1n for A4 devices)

So for now only A4 devices can downgrade to IOS 5.x.x that too using a signed/stitched firmware only !

and yes you can go back to ios 4.3.3 with saved SHSH using tiny pwn

It looks like Apple is about to aggressively combat the “replay attacks” that have until now allowed users to use iTunes to restore to previous firmware versions using saved SHSH blobs.

Those of you who have been jailbreaking for a while have probably heard us periodically warn you to “save your blobs” for each firmware using either Cydia or TinyUmbrella (or even the “copy from /tmp during restore” method for advanced users).  Saving your blobs for a given firmware on your specific device allows you to restore *that* device to *that* firmware even after Apple has stopped signing it.  That’s all about to change.

Starting with the iOS5 beta, the role of the “APTicket” is changing — it’s being used much like the “BBTicket” has always been used.  The LLB and iBoot stages of the boot sequence are being refined to depend on the authenticity of the APTicket, which is uniquely generated at each and every restore (in other words, it doesn’t depend merely on your ECID and firmware version…it changes every time you restore, based partly on a random number).  This APTicket authentication will happen at every boot, not just at restore time.  Because only Apple has the crypto keys to properly sign the per-restore APTicket, replayed APTickets are useless.

This will only affect restores starting at iOS5 and onward, and Apple will be able to flip that switch off and on at will (by opening or closing the APTicket signing window for that firmware, like they do for the BBTicket).  geohot’s limera1n exploit occurs before any of this new checking is done, so tethered jailbreaks will still always be possible for devices where limera1n applies.  Also, restoring to pre-5.0 firmwares with saved blobs will still be possible (but you’ll soon start to need to use older iTunes versions for that). Note that iTunes ultimately is *not* the component that matters here..it’s the boot sequence on the device starting with the LLB.

Although it’s always been just “a matter of time” before Apple started doing this (they’ve always done this with the BBTicket), it’s still a significant move on Apple’s part (and it also dovetails with certain technical requirements of their upcoming OTA “delta” updates).

Note: although there may still be ways to combat this, a beta period is really not the time or place to discuss them.  We’re just letting you know what Apple has already done in their exisiting beta releases — they’ve stepped up their game!

i read thru this forum just now and found out so many ppl advising to save shsh for ios5.0.1
i got this ipad2 secondhand set and according to the buyer he never jailbreak and when i got it is already 5.0.1
after i save shsh i found out that i have 4.3.3 shsh saved.. does the picture below shows that i have ios 4.3.3 shsh saved?
if yes i would like to do a downgrade since i cant wait anymore for the jailbreak..
