Ok folks. The latest iOS 5.1.1 firmware can be unlocked with SAM unlock tool provided they have saved their activation tickets.

Unlock iOS 5.1.1 with SAM tool

The people who unlocked via the SAM tool, can create a custom IPSW and run iOS 5.1.1, but right now it’s a tethered jailbreak and the untethered jailbreak is also very near!

Create Custom iOS 5.1.1 IPSW to Preserve Baseband For Unlock


Download the latest redsn0w tool.

Download original IPSW for iOS 5.1.1

Backed Up Sam Unlock Activation tickets ( Cookie or Redsn0w ).

iOS 5.1.1 Preserving baseband guide:

Step 1: After downloading redsn0w from the link above, start it.

Step 2: Go to Extras -> Custom IPSW.

Step 3: Choose the original IPSW file on the iOS device downloaded from the link above.

Step 4: Now the custom IPSW file will be created by redsn0w, the one that has preserved the baseband meaning one will still be on the previous version (baseband).

Step 5: Go to Extras -> Pwned DFU to enter Pwned DFU mode. Follow the on-screen instructions.

Step 6: Once there, go to iTunes and press Shift+Restore (Windows) or Option+Restore (Mac).You need to choose the correct IPSW file. It will have a prefix “No_BB”.

Step 7: As it’s a tethered jailbreak, you need to boot tethered while it’s trying to reboot after restoration. To do that, go to Extras > Just Boot!

Now you’ll have a custom IPSW on iOS 5.1.1 with a preserved baseband.

Unlock iPhone using SAM 5.1.1 activation ticket backup:

We have heard reports that some SAM 5.1.1 users are stuck again with locked iPhones, but we have tested the guide and we can confirm its works on iOS 5.1.1 tethered jailbreak.

Step 1: Jailbreak your iPhone on iOS 5.1.1.

Step 2: Install SAM on iOS 5.1.1.

Step 3: Revert Lockdown to stock.

Step 4: Replace the backup activation ticket (Lockdown folder) to this path: /var/root/Library/Lockdown.

Step 5: Reboot your device.

Step 6: Disable SAM.

Step 7: Reboot, and then wait for the Carrier Signals to Appears.

Update: Sam Unlock Works on iOS 5.1.1 and iOS 6.0.1

For those who have saved Lockdown folder before using the correct activation ticket you will be able to restore it after iOS 5.1.1 or iOS 6 Jailbreak!

Note: Unlock Activation Ticket is valid 3 years — more info here.

We also posted guide to factory Unlock iPhone 4 using official iPhone unlock.

CONGRATS! You have unlocked your iPhone using SAM backup on 5.1.1 firmware. Enjoy!

  • PaulH81

    Does it works with baseband 4.12.01?

  • All Jailbreak

    if you had saved your unlock tickets for your baseband, it will work.

  • Ashley2

    I Dnt understand what that means I’ve never tried to unlock it. I’m on 5.1 and 4.12.01 baseband

  • sunny_hacker

    of course! if you have backup of unlock ticket.

  • All Jailbreak

    this tutorial will work for those, who have used SAM unlock to unlock their iPhones. The SAM unlock don’t work anymore officially, but a reader in my blog tells me today its working for him. so, you can give it a try if you like. but there is no guarantee it will work now.

  • Ashley2

    Thanks! So I just follow the steps above to try it?

  • All Jailbreak

    nope, those steps are written for those who have already unlocked using SAM. you can find the steps to unlock with SAM in this blog.
    I don’t want to spam by posting my blog’s links here. try searching in this blog.

  • Goooogle99

    4S 5.1.1 jail break didn’t come yet ?after it’ll come is this method work for unlock to my carrier ???

  • Kenzo

    Did any one tried the first part which preserve your baseband with an iphone 4S?
    Please Reply cause in Redsn0w official blog says its only for iphone 4 and 3gs

  • Gerardo Bracho

    unlock baseband 4.11.08??

  • Ericklzld

    How Did you do it? I have my save ticket but i’ve tried it and it doesn’t work me :/ did you follow the steps? when i do revert to lockdown it tells me notification failure

  • John396442

    you must have a wireless connect to revert lockdown 🙂

  • aob

    I have unlocked mine using SAM but I will wait for the untethered jailbreak 5.1.1 to be release. Why go for a tethered jailbreak? Afterall it takes the same effort. Since many postings are saying it will surely come.

    can with sam tickets unlock bb 20.12 4s ???????

    plz tall me i want update to 5.1.1 ……

  • Yasmeen

    Do I need to preserve my baseband if it’s already at 4.12.01 and it was when I unlocked it with SAM?

  • Fabi

    Deactivate ur iPhone using redsn0w. Remember mark only deactivate and unmarke all.
    Thank u

  • Fabi

    Easy just go tO redsn0w mark deactivate and unmarke all. Follow the next instactions that’s all. Problem solve.

  • Aning_019

    I’m confused with step 7, you need to “Just Boot Tethered” even if you haven’t selected “Jailbreak” yet?
    I thought the first procedure is about updating to 5.1.1 while preseving baseband, then the next step is to jailbreak after a succesful update to 5.1.1.

    Or is the Jailbreak integrated on the custom ipsw? Thats why it needs to “Just Boot Tethered” while booting after restoring on step 7.

  • Sajad

    is it possible to use the Backed Up Sam Unlock Activation tickets from anyone else or even twice?

  • Gyunwu

    i just did….it updated my baseband to 4.12.01 from 4.11.08, unlocked with SAM backed up activation tickets

  • Filipla

    puoi ancora sbloccare imei at&t?? io dovrei sbloccare il mio iphone 4–tu puoi?–mio imei

  • Sajad

    Don’t know if you (Gyunwu) replied to my comment?

    – But the question is, if it works for you, could I also use your activation ticket for my device?

    – And how to change baseband? Could you enter Link for “how-to”


  • Artur

  • chelsearob77

    I have an iPhone 4 on Redsn0w software & 5.0.1 ISO & 04.11.08 baseband, currently unlocked using the SAM unlock method,

    so what i want to know is if i was to restore my phone, update to 5.1.1 via iTunes, then jailbreak my phone with Absinthe v2.0.1
    will i be able to unlock my phone again or will i lose it due to the firmware & baseband change?

    by the way i do have my SAM activation ticket & Lockdown folder saved!

    so if anyone that is or was unlocked with the Sam method & has been successful in updating to 5.1.1 & Absinthe v2.0 & unlocking their iPhones, then please do report it here please.


  • Natan Gouveia

    I unlicked my brothers phone with SAM when it came out
    but now he changed his sim card
    is there a way to unlock the phone to use this new sim card?
    the phone still works and it is unlocked for the sim card he had before

  • Natan Gouveia

    baseband 04.12.01

  • David Gonzalez

    This is bull crap, YOU CAN’T “Revert Lockdown to stock” with current SAM ’cause it’ll sit a “STOCKIFATION FAILURE” on you right away, this posts are really useless, and mostly from people that haven’t even upgraded to 5.1.1 as I have, I know this is bull… because you CAN’T use SAM on 5.1.1, and ALL and I mean A_L_L posts regarding restoring SAM unlock tickets on 5.1 or 5.1.1 WIL FAIL, DON’T upgrade to 5.1x you’ll loose the ability to re-use your unlock tickets.

  • Shaxi Shaikh

    did anyone able to successfully unlock through this procedure ??

  • Toni

    Your are great man, after several desperation tries , your instructions were the bests thanx a lot million times 🙂

    I updated to the newer SAM version after unlocking my iphone 4
    and after Apple had fixed the issue. It seem to have no effect on the unlock.
