First of all I wanted to express my thanks for this forum - this place is a wealth of resources and I'm glad it's here.
I have some questions, but I first wanted to give a little background of my situation. I am based in China and have recently inherited an iPad1 64gb and jailbroke it on version 4.3 (8F190) with redsn0w. It works well enough but I was too hasty in my jailbreak. Now I wish to restore it as there are still many applications from the person who owned it before me and some apps (like the App store) are in Chinese. Also the iPad is still tied to the previous owner and as I don't know their login/password I can't download any new apps either.
In jailbreaking I also have saved the 5.1 SHSH blob to Cydia, but as it wasn't jailbroken before there are no other versions that are saved. I know I can restore with TU to 5.1 but as I explain below I've had some troubles with that.
So I realize I screwed up jailbreaking it and wish to restore or even update it - I've read that since it's an iPad1 I'll always be able to jailbreak no matter what version. However I have been unable to wipe it clean and restore to any version because of:
1) ridiculously slow download times on the 5.1 ipsw from the appldnld link - I managed to download the 4.3 ipsw from another mirror which was lighting fast, but no such luck for 5.1. The 5.1 download will take ~24 hours, and I guess I can let it download like that but I don't want to out of principal and because it might not work even if I did. It shouldn't take that long dammit!
2) I get the 3194 Unknown error trying to shift+restore (to the same ipsw I jailbroke it on - 4.3) in iTunes even after I followed the guide - my hosts file doesn't have any mention of gs.apple.com and I disabled MS Security Essentials.
I'm wondering what I can do from here, other than sit through that download? As I already have the 4.3 ipsw is there a way to restore that way? Ideally I could solve this 3194 error (what am I doing wrong?) and be able to restore that way.
Is there a mirror out there for 5.1? If I restore will I be able to change the account that the iPad is hooked up to, and change the language of the App store (the rest of the iPad I already switched to English, but for some reason the App store didn't follow)?
Thanks for sitting through this rambling post and I appreciate any feedback!
