Have you been one of those users who want to update their device to iOS 5.1.1 firmware but afraid that you’ll lose your SAM unlock?

unlock iphone with sam

Today we have good news for all SAM unlockers, don’t worry as we have updated redsnow tool that allows you to safely restore your SAM unlock activation tickets to unlock your iPhone with any baseband on the latest iOS 5.1.1 firmware.

Yesterday the Dev Team mentioned inside the release notes that “now you can include your backed-up SAM unlock tickets in your initial ramdisk jailbreak of iPhone 4 or earlier, or on the other hand, you are able to upload your SAM unlock tickets to any device after its already been jailbroken.”

The most popular jailbreaking software — Redsnow continues to be a most important tool. After latest update Redsn0w 0.9.12b1 can now jailbreak all devices on iOS 5.1.1, however, the a very important factor most of you’ll be thinking about will be the ability to restore your SAM unlock tickets.

Last week, we posted a manual solution to restore your SAM Unlock activation tickets, but this more recent technique is preferable because of its simplicity.

How to Unlock your iPhone on any Baseband Using Redsnow

The following tutorial will work on all iOS 5.1.1 devices with any baseband including 4.11.08 and 4.12.01 and for all users who had unlocked their iPhone through the SAM unlock tool that was opened just for a few days before Apple fixed it.

Note: Your device need to be jailbroken on the iOS 5.1.1 firmware, since this can transfer the SAM unlock files. You had been also necessary to backup your SAM unlock ticket for future unlock.

Step 1: Download Redsn0w 0.9.12b1 click here.

Step 2: Now connect your iPhone to your computer and start Redsnow.

Step 3: Now Click Extras -> Even more -> Tickets and choose your Lockdown.zip file that is created when you backed-up your SAM unlock activation ticket. In the event you backed-up your tickets manually you can choose the .plist file.

Lockdown select to Unlock iOS 5.1.1 with Redsn0w
Choose Lockdown.zip or .plist file

Step 4: You need to get a confirmation message from RedSn0w stating that your Tickets are uploaded.

Step 5: Now reboot your iPhone, and test your unofficial Sim card.

Now you’ve successfully unlocked your device using Redsn0w.

    How to fix “can not connect to YouTube” issue?

  • nt21

    I dont think you should update. Update means to replace old files with new ones and if the lockdownfolders is one of the files needed to update which contains your unlock activation is update then you will most likely loose your unlock.

  • Nathan

    I didn’t do the SAM method way back, but I have a major question.
    Is it possible to share the lockdown file between phones? Like would you be able to share that file with me and I will add that into my iphone, and if there are some info I need to edit like IMSI. Will it work?

  • Nathan

    Is the Lockdown file modifiable where I can make it compatible to my iPhone 4?

  • Chakravarthy CRS

    hi i am stuck with 4.11.08 and 5.0.1 could not unlock with SAM earlier. Is there a solution yet for the users like me.

  • HB

  • Iliana

  • OnlyTheBrave

    hi there

    thank you very much

  • joe

    can you unlock the baseband 4.11.8 and 4.12.01 ?? ore is this just for those who saved their unlock ticket through sam ??

  • AndrejVarabej

    Hi, I have only two questions.
    Can i unlock my iPhone 4 bb 04.11.08, 5.0.1 if i don’t have before use SAM unlock?

    And other question, if i have SAM unlock but i want use another Sim card but on the same carrier this method does work????

    Thank you and please repeat me.

  • praveen

    do we need the original sim to activate the phone………I dont hav the original sim….what to do..

  • Toni

    I would like to share with you guys something so read this carefully, When SAM unlock method came out I have unlocked my iPhone with two SIM cards of Mobile Providers that are available here in my country and I have saved activation records for both of those SIM cards, so one day I had an Idea I have putted in my Lockdown folder both of Activation records and wow what happened, I can use both sim cards like it was full unlocked iphone , only by replacing SIM cards and without need of any reboot, Signal Bars come automatically.

    So I just wanted to share this info for you that have saved more than one activation ticked and you think that whenever you want to activate another SIM card you need to delete previous Activation Tickets and than you have to reboot iphone and so on….so in fact you don’t need that procedure only copy and paste activation records that you have saved previously – paste them in Activation Records that you can find in LOCKDOWN folder and that’s it !!!!

  • Genesis_way@hotmail.com

  • Vic

    Guys, here’s a situation: when I unlocked my phone with SAM, it had the previous iOS and 4.11.08 BB. Then I saved tickets.

    Now I updated my phone to latest iOS (5.1.1) without preserving the Baseband (so it updated too).

    Question: should the restoring tickets thing work now? (I tried many times, and it doesn’t. Maybe there is smth wrong I do)

  • Vic

    please ignore. already answered by someone else. (btw, still doesn’t work)

  • Filip

    I have backed up my ticket but I changed my sim (same carrier and number) will I be able to unlock?

  • Exoreck Hospeck

  • Exoreckk

    Anyway you still need an official Sim ( AT&T)

  • Leoxxx

    Can i use the sam ticket for unlock other iphone 4????

  • azyan

    Where did you guys got the lockdown folder?

  • azyan

    Did you mean that you unlock your phone using SAM again?

  • Paulo

    Use latest Redsnow 0. 9.12.b2 and during jailbreak when your going to tick hacktivate install cydia theres an option restore activation ticket do that and it will be jailbroken plus activated.
    !!!!ONLY FOR THOSE WHO BACKED UP THEIR ACTIVATION TICKET AND WITH THE SAME SIM AND SAME IPHONE ONLY!!!! HARDWARE IDS CANNOT BE BYPASSED!!! Also not that the backed up Lockdown folder must be in the format lockdown.zip and of primary folder ie /Lockdown/*.* (and not /var/root/……/lockdown).
    Till now still no unlocking method for baseband 4.11 , 4.12 if not yet done by SAM.
