Updated SAM 0.1.16-1 Unlock tutorial easier than ever
APRIL 27th 2012 - The SAM unlock has been patched. I attempted the unlock on two phones I unlocked just yesterday with no issues and today they will not activate. If you saved your unlock ticket, you are safe.
@sbingner has updated the SAM package to make the SAM unlock method even easier. We have had several reports of successful unlocks on our previous SAM unlock tutorial, but we also had an equal amount of people who could just not get it to work. Hopefully the updated version of SAM will help you finally get your device unlocked!
The best part about the updated SAM package is that you no longer need iTunes and most importantly, you don't need to worry about your country/carrier and SIM IDs anymore(which seemed to be the biggest issue for people using the initial tutorial).
Step 1: Install Sam Bingner's SAM package from Cydia. You can get it from Sam's repo which is http://repo.bingner.com make sure to use the newest version(0.1.16.-1 at the time this tutorial was created).
Step 2: Deactivate your phone(Using SAM) and insert your unofficial SIM card that you wish to unlock to.
Step 4: That's all there is to it, your device should respring and your should have signal on your unofficial SIM. Pretty simple huh?
Just like the initial tutorial there are known issues with this new method. If you complete the steps above and you receive an error(specifically You must select the original carrier SIMID of your iPhone), attempt the following to fix the issue:
Step 1: Remove the SIM card from your phone.
Step 1: Download, install and open iFile and navigate to /var/root/Library. Tap edit in the upper right-hand corner and select the Lockdown folder. Tap the zip button to backup all the files in your lockdown folder and then delete the lockdown folder(make sure the backup is still in tact).
Step 3: In iFile again, navigate to /User/Library/Preferences and search for SAM(at the top) and delete the com.bingner.sam.plist file.
Step 4: Power off your phone and then turn it back on.
Step 5: Insert your unofficial SIM card.
Step 6: Open SAMprefs go to Utilities and tap Attempt Activation. You will receive a dialogue stating that it may take a while. After your phone resprings, you should have signal on your unofficial carrier.
As always, please report below if you have tested this method and whether it worked or not as well as information about your device and carrier. Thanks!
