Ticket SAM works on 6.1?:

UnlockBoot

Yes.

Edd

What is your opinion of the 04.11.08 and higher basebands?
Is there going to be unlock with SIM interposer or software unlock?

Is that even possible or something that we can forgot about?


I think that the only solution is factory unlocking (which is way too much expensive for some carriers), not because hackers can't unlock it, but because they don't want to.

Ariel Carcas

Hello everyone! I have jailbroken my iphone 3gs with evasi0n. Now as you may know i have the "no service" issue. Well... I read all this and found out that this ultrasn0w fixer for ios 6.1 is not compatible with baseband 05.16.08 which is the one on my iphone so my question is: I there going to be an ultrasn0w fixer version compatible with this baseband? Is there anything I can do meanwhile? Thank you very much for your time.

Ariel Carcas

I am ios 6.1 btw...

Try downgrading BB from 6.15.00 to 15.13.4 using redsn0w_win_0.9.13dev4, then create IPSW thru sn0wbreeze-v2.9.9 for iOS 6.1, then install ultrasn0w 1.2.8, and you will not have to wait for the signal to come on. After reboot you'll see the signal in sec. BTW, I am using iPhone 3GS/iOS 5.1.1/BB 6.15.00 (Before), iPhone 3GS/iOS 6.1/BB 15.13.4

vanjo tapang

Same problem here.

Rob Thompson

use the latest version on redsn0w then click on extras then click on even more then click on where it says tickets: put back saved activation tickets, then you will be able to navigate to where your saved activation ticket/lockdown folder is on your computer & be able to place it onto your phone!
then reboot/power off your phone then your activation ticket will work!
