TUTORIAL - Re-restore IOS 5.x on iPad2 and iPad3 using redsn0w and SHSH Blobs

Problems like the one you are describing are almost certainly related to your PC. Interruption to the communications are a good indicator that something is interfering with the process. Anti-virus, malware, Windows Defender, firewall etc. are usually to blame.
It could also be the use of a bad USB port, hub, incorrect cable, etc. (using a cable that was not for the iPad can often have adverse effects on restore operations - particularly older iPhone or iPod cables). Finally, ensure you have the latest iTunes as the drivers need to be current.

Disable as much as you can before you start, ensure you are connected directly to the motherboard (no hubs), and try again. If you still can't get it to work on your PC, the best bet is to try someone else's.

Good luck.

Appreciate assistance but none of that seems to apply. Even with AV off, Def off, firewall off, different cables, different USB ports -both USB 2.0 & 3.0, while running the latest itunes version.....and THEN doing it all again on my other PC; I'm still getting exactly the same error in exactly the same point in the process. The iOS is RIGHT! It's the original firmware supplied with the ipad so there can be no doubt about the file. :(

Ahhh, was the current version of IOS on there, factory installed? In other words, you did not install it on there yourself?
If so, you will not be able to re-restore. Factory installed IOS is initialised in a way which is different from a standard restore, which would account for the message you are seeing. (see the note at the start of the tutorial, which I've updated to make more explicit about new devices).

I hadn't come across this issue myself but the dev-team did warn against this scenario, and I assumed you would get a better error message, but this is likely what has happened in both these cases.

There won't be any work around for it AFAIK. Your APTicket cannot be made to match the blobs you have saved. :(

Right, well that's that then.:) I guess we've managed to continue the testing process and evolve the tutorial one step further.

Doesn't help me unfortunately as I wander off to itunes and 6.01 while waiting impatiently for the next jailbreak. :(

Hello all,
so I have an ipad 2 recently updated to 6.0, and with this tutorial I was able to successfully go back into the 4.3.5 firmware.
However, I am now trying to 'upgrade' back to 5.1.1. I follow the steps again and I can see the processes loading 4.3.5 and when it is time to load the 5.1.1. it gives me the message 'Service would not start" and just leaves me hanging on the apple and loading bar screen on my ipad.

I am trying to update on a PC, and I am running the application as administrator. Anyone have ideas how I can go abouts updating form 4.3.5 to 5.1.1?
I have all the blobs saved on TinyUmbrella as well. (both the 4.3.5 and 5.1.1)

I'm having the EXACT same problem! Every time I use redsn0w to downgrade to iOS 4.3.5, it ALWAYS works. But whenever I tried to downgrade to 5.1.1, it always shows "Wouldn't start service". I followed everything on the 1st page and read through everyone's comments in all of the pages. My TinyUmbrella and host file etc are correct (otherwise I wouldn't have downgraded to iOS 4.3.5 using redsn0w). But somehow I just can't downgrade to 5.1.1, and YES I DO have the 5.1.1 shsh blobs saved. I tried both local and remote but still shows "Wouldn't start service"......

Oh and my iTunes is the latest v11.2.


NVM got it working!!!

I dunno what I did, but I think it's because I upgraded to the latest firmware (iOS 6.1.3 as of this writing) then trying the exact same method again. So ya, redsn0w downgrades to iOS 4.X (which is iOS 4.3.5 for me as that's the only one that has my saved shsh blobs), then upgraded to iOS 5.1.1 (again, with my saved shsh blobs) and somehow it went through perfectly without the "wouldn't start service" error.

I've been struggling on this for a day now I cant get it to 5.1.1 or 6.0.1.. I have the same setup Ipad 2 - 4.3.5... I only can downgrade but can upgrade pass 4.3.5. I usually get an error message 3194 if I upgrade to 6.0.1.. When I upgrade to 6.1.3 and downgrade to 6.0.1 or 5.1.1 it gives me an error message. The only ipsw i can downgrade to is 4.x without error. Can you tell me exactly what you did? Did you use local or remote?

Haha NVM too I guess I figured it out.. I closed redsn0w and restarted under run as admin and it worked. Now, will this work with 6.0.1?

Hey man, well first of all I didn't get a particular error number like your "3194" or whatever. I simply got the message "wouldn't start service", that's it. Secondly, I tried both local and remote, and already ran redsn0w as admin since the start. It just somehow worked after so many tries, dunno how I did it because I didn't change my method or anything else, I just kept trying the same procedures.

As for 6.0.1, I've tried that but there was a problem with aptickets, so I stayed on 5.1.1 in the end.
