Did you run the Command prompt in Administrator mode?

I have windows 64bit and only a single user, so by default it is in administrator mode right?

If you’re running Windows Vista/7, then you need to enable Admin mode.

Hey, I want to jailbreak my Iphone 4s 5.1.1. But my iphones i not activated because i got it from my uncle in london, and i live in sweden. I cant get the right simcard to activate the Iphone. Well as i’ve noticed the dev team are against piracy so they made the new jailbreak tools so they wont jailbreak unactivated A5 devices, because in order to jailbreak my Iphone 4s that is unactivated I have to enter DFU mode and then jailbreak, but as i said the dev team made it so the A5 devices wont jailbreak in DFU mode. So my question is, is there any way to jailbreak a Iphone 4s (A5 device) 5.1.1 in DFU mode. Or is there any other way to Activate my Iphone 4s without the right simcard (At&t) locked.

The jailbreak with absinthe gives this error ( Your device is not activated. please activate the device…)

The jailbreak with redsn0w gives this error (Your device is not activated)

Note; when i enter DFU mode to jailbreak with redsn0w it tells me that my phone is is wrong mode, it wants me to be in normal mode (not DFU), and that wont work ofc.

I appreciate all help, thanks! Btw there is a lot of peoples in my situation.

Hi,

Currently there is no exploit to hacktivate iPhone 4S. iPhone hackers are working on it still. In the meantime, you can buy AT&T micro sim from eBay.com. You’ll get it for dirt cheap & it is not necessary for the sim to be active. Use this sim to activate your iPhone & then jailbreak.

So will a At&t Go phone simcard, that is not activated yet work?

Thanks.

Mahesh Kukreja June 9, 2012 at 9:19 pm

Yes any AT&T sim card will activate your iPhone.

Btw, i orded a gevey ultra s, I will get it next week. Do u think that one will work to activate?

Gevey ultra s only unlocks iPhone 4S. It won’t activate your iPhone.

Ok, Thanks you for all the help! 🙂

Hello, I orded a At&t Gophone sim card from ebay… But it doesnt activate the Iphone .. I have no service because i live in Sweden. It gives me the error “Only compatible Sim cards from a supported carrier may be used to activate iphone etc..is that because i have no service?

Mahesh Kukreja June 15, 2012 at 6:30 pm

It is not necessary that the AT&T sim card must be active. Please give the link of eBay item that you purchased.

Robin June 15, 2012 at 7:14 pm

http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=270959486080#ht_2124wt_1189, there is the link.

Note that I plugged it it first and tried, then i read that i have to activate the sim card, so I did it trough their website but after all it didn’t work.. 🙁 I appreciate all your help!

Are you sure that your iPhone is locked to AT&T? You’ve mentioned that your Uncle (from London) gave it to you. If your iPhone is locked to AT&T, the sim that you’ve bought should activate it.

Robin June 15, 2012 at 7:28 pm

Well actually i think it is locked to at&t because i entered the springboard trough the 112 bypass trick, and then i went to settings>general etc, and it was written at&t on carrier even though i didnt have a at&t card inside and never had. So i belive it is at&t locked. But one thing i just saw by doing that trick and look at general was that the model is : md242b, and if u search that model on google u will se that it is Factory unlocked in UK.. This is so wierd.. Well I am sorry for being a pain in the ass.. But of course i appreciate all your help !
