Unlock iPhone 4 baseband 4.11.08 (Guide)

Lets just directly jump in to the step by step guide showing you how to unlock your iPhone 4 and iPhone 4S on a variety of basebands.

Important Notes:

  • Works on all iPhone 4 basebands including 4.11.08 (many have reported they unlocked iPhone 4 baseband 4.11.08 using this technique
  • Works on all iPhone 4S basebands including the ones on iOS 5.1
  • Some of you might face problems using this as this is quite technical, SAM developer has mentioned that they are going to update it so it becomes easier for you.
  • Make sure to save your activation ticket. Backup everything in /var/root/Library/Lockdown/
  • This method works on iOS 5.1 as well.
  • This method to unlock iPhone 4 baseband 4.11.08 will work with a specific SIM card as it has been tricked to ICCID is one of the intended carrier’s.
  • Push notifications may stop working after this procedure but can be easily restored with “clear push” utility in SAM followed by connecting to iTunes.

Step By Step Guide On Unlocking iPhone 4

UPDATE: As requested we have added a video guide for those users who are still stuck. Check the video guide by CLICKING HERE.

STEP 1: Install SAM from Cydia. To do this head over to Cydia > Manage > Sources and at the top right corner tap edit and enter this repo:

http://repo.bingner.com

I suggest you to install SAM from the source above as others might be outdated.

STEP 2: Once SAM is installed you will see it in your springboard. Just tap on SAM to enter it. You must have the SIM card you want to use in your iPhone with you.

STEP 3: Once enterd into SAM, head over to utilities and select “De-Activate iPhone”, your ActivationState under “More Information” should now be “Unactivated”

STEP 4: With SAM enabled, choose “By Country and Carrier” in “Method”; find your carrier, for some carriers operating more than one Carrier ID you may need to select “SIM ID”; easy to tell since iTunes will not activate if the wrong IMSI is selected.

STEP 5 :Go to More Information”, copy or write down the IMSI in “SAM Details”, then tap “Spoof Real SIM to SAM”.

STEP 6: Go back to the main SAM screen and change your “Method” to manual. Paste or enter the IMSI string that was saved in Step 5.

STEP 7: Now you need to connect your iPhone to your computer by connecting it with iTunes. This is to re-activate your iPhone.  Double click “Phone Number” parameter at the main device screen to make sure ICCID matches exactly with that of your SIM card. If it does not match you will need to start from step 1

We have got some reports that some people are people are having problems with step 7 as iTunes displays a message: SIM card not compatible. To fix this problem you have to make sure that ICCID matches exactly as that of your SIM card.

Follow this guide to fix SIM Card Not Supported Error

STEP 8:  Close iTunes and unplug your iPhone 4.

STEP 9: Now simply Disable SAM, no need to delete it.

STEP 10: Now you have to connect your iPhone 4 to iTunes, you will get a message saying it can not be activated. Do not worry this is part of the process. Just close it and open again.

STEP 11: Are you seeing signal bars? If yes then congratulations!

You have managed to unlock your iPhone 4 baseband 4.11.08, congratulations on your success. Let us know in the comments below if this method has worked for you!

  1. hey if u guys have trouble step 4 to step 7 just auto detect it and start off from step 7 after that it worked for me :)).

  2. hahahahah got it to work on my iphone 4 basband 04.11.8 cheerrssss, its very easyyy. SAM is going to be updated for you to be easier. Its important to know which carrier your phone is locked to.

  3. Step 7: “Double click “Phone Number” parameter at the main device” What does that mean, where can i find this parameter on which main device? Please help..

  4. Works on 3GS too. :) If you have some problems activating see here:

    jaxov.com/2011/05/fix-sim-card-not-supported-error-while-activating-iphone-with-sam/

    I used the bundle activation and didn’t spoof anything and it also worked. Just make sure your ICCID in iTunes matches the phone’s.

  5. Double click “Phone Number” parameter at the main device What does that mean, where can i find this parameter on which main device? Please help..

  6. confusing steps, should I insert the sim I am trying to use with (vinaphone) or the carrier sim locked to? (Rogers Sim) before starting step 1?

    • The SIM you are trying to use. The locked one you dont need. You just need to know for which carrier it is locked to. Because you need to select it in STEP 4. Luck…

      • Thank you for your clarification and it worked. I hope maypalo re-phrase it so everyone can understand it better.

    Hey everybody. I bought a phone off the internet and I have no simcard for that country. I think it’s poland or something. Is there any way of getting past the activate sim page? The ’112′ emergency call doesn’t work with 5.1. any help would be awesome!

    • Da TIM! Pelo que entendi vc tem que selecionar AT&T no passo n. 4. Ainda nao testei aqui pois o iphone travado nao ta comigo! Na ansiedade! Boa sorte!

  8. Two questions: Do I need to keep the SIM i want to use inside the sim tray all the time?
    what if “Spoof Real SIM to SAM” doesn’t shows up?

  9. Thanks, it works, I have been waiting for the AT&T factory unlock for more than a week but this came first. Thanks again.

  10. i am confused.. do i insert the sim card from the original carrier or the sim card i am trying to use?.. i think i did something wrong

  11. when i press de-activate it says de-activated but when i look to more information it says, factoryactivated and not unactivated ?

  12. So, does this unlock method works for a specific SIM card, or does it unlock it for a specified carrier?

    If I use my friend’s SIM card for the unlock process, then I would always need to use THAT SIM, or may use another SIM (but of the same carrier)?

  13. 1-What if I update again?
    2-or later want to change the SIM?
    3-will it need the original SIM later in future? (because I don;t have it)

    • Never mind, I got full signal bar now. For those of you having trouble following the steps, please re-read carefully and make sure your sim is properly inserted, if it said no-Sim found, the cause is probably your sim is not inserted properly.

      Today is a good-day so lets all be thankful to loktar_Sun.

  14. tried on two iphones one 4.3.2 one 5.0.1 both different basebands tried for hours thinking i have made a mistake but always got the same sim card not supported even after trying the fix… carrier au telstra

  15. Got it as Phone now after 5-months worked as an ipod… thanks to all who worked hard to get this unlock…. thank you so much….

  16. Its worked for AirTel India… Phone is working SMS is working … have to check all other features…

  17. ok i have a question, ive unlocked my iPhone 4 and it worked, but i unlocked it using a t-mobile sim so if i insert another t-mobile sim do i have to do anything with SAM again or will it work fine, the reason i ask is i used a really old t-mobile sim i had laying around and cut it into a micro sim to do this unlock but later today when t-mobile opens im going to go get a real micro sim and start a prepaid plan, but at the moment with this regular sim cut into a micro sim even after unlocking my iPhone 4 says searching, or no service, but im guessing its saying that because its not a true micro sim and that part will be fixed when i get a true micro sim . so my question is will my iphone work without having to do another unlock with SAM if i put another t-mobile micro sim in it?

  18. GUYS IT WORKED FOR ME AS WELL… on BB 04.12!!!!
    IT’S A REAL MIRACLE LIFE SAVER FOR ME..!!!
    i had accidentally updated to iOS 5.1 without saving the baseband..!!!

  19. A BIG AND MEGA THANKSSSSSSS!!!!YOU MADE MY DAY!!!!!!!!!!THANKSSSSSSSSSSSSSSSSSS YOU VERY MUCHHHHHHH!!!!!!!!

  20. Works PERFECTLY!!! No trouble at all. Many thanks to everyone that worked on it. We can take that little mark out of Apple’s win column and put it into the hacking community’s. I am so happy that I no longer have an expensive paper weight.

  34. Can someone please help me? Locked on Telstra in Australia, I don’t have the original sim, since I am in the UK now. Have tried all sim IDs but still getting this apple error: ” The Simcard inserted in this iphone does not appear to be supporte…please insert the simcard that came with the iphone”. I don’t have it anymore; have been using this phone as ipod for the past months. Can someone please give a detailed explanation to bypass and/or unlock with SAM? Thanks in advance!

      • Flávio Barbalho

        Pelo que entendi o chip que ele deseja utilizar ( apos desbloqueio) é da TIM. É isso?
        Se for, o modo automatico, vai funcionar. (Acabei de fazer em outro Iphnoe4 para TIM.
        Lembrando que é importante saltar os tickets de ativação (o seguro morre é de velho).

        • Caraca gente. Tambem estou tendo dificuldades com o chip da tim/vivo. Ja tentei no modulo “by country by carrier” no “by bundle name” e no “auto detect” nenhum funcionou. Sera que voces podem passar um passo a passo da ativacao no modulo automatico? Muito grato.

    BOA SORTE A TODOS!!!!!!!!

    FARHAM THIS IS FOR BARZILIANS WHO COULD NOT UNLOCK IT BY FOLLOWING THIS METHODS. THANKS!!!!!!!!!!!!!!

    • punonte po e mbyllen :( e kush nuk e beri save e humbi unlockun prap kshu me ndosdhi mua e hapa dhe u mbyll mbas 2 ditesh :(

  36. There is no VIVO carrier from BRAZIL!!!! What shoud I do? Is there anyway to fix this? The list of carriers don´t exist anymore.

  37. Did it on the first try,easy steps to understand & follow,I now have my iPhone 4 bb 4.11.8 unlocked to Vodafone from Portugal…great job guys,thanks

  38. Will this work only one time? I was able to unlock mine with a t mobile sim but the time wasnt showing on the top dock so I reset the phone settings and I lost the unlock. Now everytime I put in my t mobile sim it says invalid sim and sim failure and in itunes it says no sim card is installed. I tried with sam many more times and I cant get it to unlock again.

    • zdravo Nislija, mozes li molim te da mi pomognes oko aktiviranja jer nikako ne uspevam. hvala unapred

  39. Mine unlocked properly but for some reason after i put a brand new t-mobile microsim in my iphone 4 my iphone spends 95% of the time either searching or says no service and the other 5% it says t-mobile and shows 3 or 4 barrs, does anybody know how to fix this damn searching or no service?

  40. Done!! Thanks Maypalo… for your efforts. Thanku to Sam Bingner and all who managed to get this unlock for us… Congratulations!!

  41. woooohoooooooooo…. Finally…. i converted my iPod Back to iPhone. Wat a relief. I got it working in the first attempt… All gud…

    All thanks to Locktar_Sun…….

    Thanks…. an cheers mate…..

  42. Thank u so much! My iPod is finally an iPhone!

    I was locked to at&t and wasn’t eligible for the unlock by them so to finally be able to use it as a phone after months makes me happy. However facetime wasn’t working. I think it was coz I wasn’t on the latest software. So I updated whilst preserving baseband and voila! My iPhone is no longer jailbroken and the unlock is still there and facetime is also working!

    Thanks for the unlock! Very very grateful iPhone user!

      • I didn’t update the firmware, my firmware is still 4.11.08. I updated to ios 5.1 whilst preserving baseband 4.11.08.

        I followed this link to update:

          • No I didn’t have to.

            I used the SAM unlocking method first but since facetime wasn’t working, I updated following the instructions in the video. After my phone re-booted, the sim I unlocked via SAM was still working. So no, I don’t think you have to do the SAM method again.

  43. Come on guys stop thanking Maypalo, they delivered the news, loki_Sun
    should be thank here. He did succeeded where others have failed miserably (R-sim, Gevey, and whats the phony ass Musc…hacker?). We should give him all the credits, he deserved it.

  52. can’t download SAM for some reason…it keeps saying POSIX: Operation timed out..anyone has this problem and knows how to fix it? thanks!

  53. hi every body, i have a pblm with itunes, every time i connect my iphone to activate it (step 7) it gives me lot of errors messages of Syncserv.
    i reinstall it many times but without result, is there any other tools???

  54. Can’t add the source. I keep getting the timout error right away. Sometimes it starts to download and then at the end it says it couldn’t fetch repo.bingner.com and it skipped some files.

  55. When I go to install Sam it says that it cannot comply: “the requested modifications cannot be applied due to required dependencies or conflicts that cannot be automatically found or fixed.”

    what should or can i do?!

  56. Mesi anpil, muchas gracias, merci beaucoup, thanks après plus de 8 mois mtn j’arrive a utiliser mon iPhone 4. Merci!!!!!!! Je suis fou de joie….

  57. I don´t know what was the carrier of my iphone :( does not works for me :( .. anybody knows what carrier use model mC603E ?

    • you do not need to know what was your carrier, you need to know your present mobile operator who provided you with the sim card you already using in old phone

  58. hey this actually WORKS!! the just follow the steps and it will most likely not work but all you need to do is keep playing with SAM and keep copying and pasting the IMSI and switching the “By Country and Carrier” to “auto” in “Method”. THIS DOES WORK! just keep trying and playing around with the steps.

  59. i had a problem with last step to activate on itunes because it said to me to “sim card not suported” but I unplugted it an pluging in so many times even clicking on apple i the middle itunes window until i got the message that it can not be activated. I unpluged and pluged two times and i got the signal

  60. OMG …. waiting for 6months and it’s unlock just like snap you thumbs !!

    BIG Thanks for loktar_Sun and Maypalo who bring this tutorial :)

    \O/ \O/ \O/ \O/ \O/ \O/ \O/ \O/ \O/

  61. mine still says sim unsupportted even though i did the steps on how to fix. and i dont get signal bars. it always say “NO SERVICE”… what to do? can anybody help me with this?

  62. the version of SAM you have mentioned from repo.bingner.com cannot intalled but version 0.1.14-2 is installed instead please help me out

  63. Mine Still says no Service… I can see the phone is “wildcardunlocked”

    Tried all manual as well as auto. I am in India…have vodafone carrier.
    Plz help

  64. I dont get the wildcardactivated. It still says unactivated. I tried this steps and the bundle name

    • You need to connect your iPhone to the computer and open iTunes after completing all the steps. Then you’ll get the wildcardunlock status. Patience is the key.

  65. I have select “De-Activate iPhone”, but my ActivationState under “More Information” is still “Factory activated”. why ?

  66. I followed all the steps and it activated my phone no problem, I see the Vodafone 3G logo. I can access full 3G data but I have NO BARS and can’t make calls or send text.

    I have tried re-jailbreaking and de-activating a few time now and still the same no SIGNAL BARS but full 3G :(

  108. hi, i fixed the sim card problem but it still shows no service..?? i got the activation state to “wildcard activated”..plz help!

  109. Step 1 itself is failing for me. I am not able to instal SAM.
    I am getting the following error:
    Did not find Repository
    The indicated repository could not be found. This could be because you are trying to add a legacy installer repository (these are not supported). Also, this interface is only capable of working with exact repository URL.

    Pls advise.
