This week Chinese hacker Loktar_Sun granted the world with a simple iPhone unlock solution by tricking Apple’s activation servers via Sam Bingner’s SAM jailbreak package (aka Subscriber Artificial Module). iPhone users from different parts of the world were able to unlock their iPhone 4S, iPhone 4, and iPhone 3GS on any baseband (including 02.10.04, 04.10.01, 04.1.08, 04.12.01, 1.0.13, 1.0.14, and 1.0.11).
The SAM unlocked iPhone included all the features of iPhone sans contractual obligation and choice of networks galore. The method proved highly successful to those who failed to get their iPhone IMEI unlocked via AT&T’s official route.
It wasn’t long ago that SAM unlock utility hit the masses and barely after 5 days, Apple fixed the hole in their activation server who served unlocking millions of iPhones. New users will not be able to unlock their iPhone devices using Sam software. If they try, they will get this error:
“Sam Notification: Activation reports Error Activationinfo rejected. You must select the original carrier SIMID of your phone”.
Those who have already saved baseband activation tickets via SAM trick still work. If you haven’t backed up your activation tickets via redsn0w or SAM, it’s too late. The process for restoring activation tickets is fairly simple. Just SSH to var/root/Library and then replace Lockdown folder with one you saved earlier.
Read on and follow our step-by-step guide for restoring SAM unlocked activation tickets to unlock your iPhone. It is important to note that the activation ticket is tied to a particular SIM - just the one being used during the trick. As long as you own the SIM card used in the unlocking process, the iPhone will show you the network signal bars. Be sure you do NOT attempt to unlock for another SIM card.
Restoring SAM Unlock Activation Ticket
STEP 1: Insert the SIM card you unlocked it via SAM trick and backed up your activation tickets.
STEP 2: Disable SAM under SAMPrefs.
STEP 3: Email yourself the zip file created when you saved your valid baseband unlock ticket and open the attachment. You will now be prompted to select an application to open the attachment file. Choose iFile (assuming that you have already installed iFile app).
STEP 4: Select the Unarchiver option and tap the Done button after the file is extracted successfully.
STEP 5: Tap the Edit button available at the top right of the screen and select the Lockdown folder that was just extracted.
STEP 6: Tap the Clipboard button situated at the bottom right of the screen and select Copy/Link from the popup menu. Then tap on to the Done button available at the top right of the screen.
STEP 7: Press the back button at the top left of the screen to go to the /var/root/Library folder. Tap the Edit button at the top right of the screen and select the Lockdown folder.
STEP 8: Press the Trash icon at the bottom of the screen and choose Move File to Trash.
STEP 9: Tap the Clipboard icon at the bottom right of the screen and choose Paste
STEP 10: Tap the Done button at the top right of the screen then reboot your iPhone.
STEP 11: After reboot, your iPhone should now be running on an unofficial network.
Go ahead and try it if you are up to it. Were you able to successfully unlock your iPhone again via saved activation tickets? On what baseband and model were you able to unlock your device?
