Unlock iPhone 3GS Baseband 5.16.08 on iOS 6.1.2 – How To

These days Apple is releasing new iOS updates frequently as compared to previous iOS updates that were released after months or few weeks. After the release of iOS 6, the most advanced OS for iPhone/iPod/iPad, Apple has released about four new iOS 6 updates in preceding month. The first update for iOS 6 was iOS 6.0.1, then iOS 6.0.2, then iOS 6.1, then iOS 6.1.1, and now iOS 6.1.2. The difference of the arrival time in each of them was months, but it ended up in weeks. In addition to all these updates, Apple is working on another update of iOS 6.1.3 for iPhone/iPod/iPad release planned in upcoming weeks.

This frequent release of iOS 6 updates make the iOS Hackers to update their Jailbreaking Tools at the time of release and users to update their iPhone/iPod/iPad to latest iOS 6.x.x version, so they can stay up to date with latest Untethered Jailbreak version along with iOS version as well. When it comes to updating to latest iOS version, the users owning an iPod/iPad are safe where as people owning an iPhone are not. The owners of iPhone at first need to make sure about the lock status of the iPhone.

Is the iPhone locked or unlocked (Factory Unlocked) because updating may result in baseband update that leads to lock again. The iPhone’s that are Factory Unlocked got no such issue because they are Unlocked for life. Therefore, people owning a Factory unlocked iPhone are free from the lock thing. Only people depending on the Unlock are in the danger zone.

Over here, mostly people owning an iPhone 4S, iPhone 4 and iPhone 3GS are in danger zone because there is no software unlock for them excluding iPhone 3GS. The iPhone 4 can be unlocked with the help of GEVEY SIM on until 4.10 baseband and the iPhone 4S can be unlocked until 2.10 baseband via GEVEY SIM. As far as iPhone 3GS is concerned, it can be unlocked on any new baseband using the iPad Baseband.

Therefore, lets start with the tutorial on how to unlock the latest iPhone 3GS 5.16.08 Baseband that comes with iOS 6.1.2 update. Please note that this guide is only for iPhone 3GS users having iPad Baseband or having old iPhone model of 16GB, 32GB. Please Read this information before proceeding on with the iPad Baseband Update on any iPhone Model.

How To Unlock iPhone 3GS Baseband 5.16.08 on iOS 6.1.2

Before we proceed on with the steps, there are some files that you need to download and requirements that should be met to fulfill unlock on iPhone 3GS 5.16.08 Baseband.

Requirements:

  1. Download iOS 4.1 or any iOS of which you got SHSH Blobs saved in Cydia.
  2. Download Redsn0w 0.9.15b3.
  3. Download Sn0wbreeze 2.9.11.
  4. Download Forecast
  5. Download iDectector for iPhone 3GS (Optional)
  6. Grab some patience.
  7. In case of any Error occurs during the process, here is the solution for all Errors.
  8. Don’t forget to back up your iPhone before following the procedures below using this guide present here.
  9. This Method is preferable for Windows Users only. MAC Users can follow the steps until Baseband Downgrade/Update and Re-Restore. They cannot follow Step 3 because Sn0bwbreeze only supports Windows and Redsn0w isn’t updated.

Download all the files from here.

Who Should Download Redsn0w 0.9.15b3?

People who want to update to the iPad Baseband and Downgrade it should download Redns0w 0.9.15b3. in other words, who want to unlock the baseband should download Redsn0w 0.9.15b3 and those of you who are on 6.15.00 and want to downgrade the iPad Baseband should download Redsn0w 0.9.15b3.

Who should download iOS 4.1 or iOS Version of which the Blobs are saved in Cydia?

Every one who wants to unlock the iPhone 3GS 5.16.08 baseband and 6.15.00 baseband on iOS 6.1.2 should download iOS 4.1 or download any iOS version of which SHSH Blobs are saved in Cydia.

Who Should Download Forecast and Why?

This tool of Forecast is an amazing tool made by ih8sn0w. It helps a user to detect the status of iPhone if it can be Jailbreaked, Unlocked or not. Therefore, we are recommending this tool for iPhone 3GS users, so they can see if they are eligible for the iPad Baseband update or not.

forecast_iphone_3GS

Who Should Download iDetector?

We do not recommend it, but people can download to see the status of their iPhone 3GS if it is Old Boot Rom or New Boot Rom.

Now the tutorial starts:

Step 1:

After you have downloaded all the required files from above, now we will start with the first Step of the process that is Re-Restore. This step is useful for the iPhone 3GS users who are on iPad Baseband 6.15.00 and on 5.16.08 or less.

  • How to Re-Restore on Previous iOS Version using Redsn0w 0.9.15b3

This is the option in which you will need iOS 4.1 or above of which SHSH Blobs you have with you on Cydia Server.

Even if you bought the iPhone with stock iOS 5.x.x or iOS 6.x.x, don’t worry, Apple is still signing iOS 4.1 for iPhone 3GS only. Therefore, users can always jump back to iOS 4.1 on iPhone 3GS.

  1. Open Redsn0w
  2. Go into Extras
  3. Now go into Even More
  4. When you are in Even More, you will see an option of Restore. Press that.
  5. After you have pressed Restore, it will ask you to browse for the IPSW first. After you have browsed for the IPSW, it will ask you to browse for the SHSH Blobs.re_restore_iphone_3GS
  6. In browse SHSH Blobs, it will give you two options; we would prefer the remote blobs server option that is the second option.
  7. Now sit back and relax while your iPhone 3GS is being restored to iOS 4.1 or any iOS of which you got the SHSH Blobs.

Step 2:

  • iPad Baseband Updating Process:

Before you proceed on with the iPad Baseband Downgrading below, you need to update the iPhone 3GS to the iPad Baseband 6.15.00. If you have already got one, then follow the iPad Baseband Downgrade process below. This method is recommended for people having a baseband greater than 5.13.04 that is 5.14, 5.15, and 5.16.

unlock_iphone_3gs_5_16_08_baseband

  1. Open Redsn0w
  2.  Go to Jailbreak
  3. Put your iPhone into DFU using the steps
  4. Redsn0w will identify the iPhone and will proceed on
  5. After DFU, Redsn0w will show you a screen like this

ipad_baseband_dowgrade

              6. All you need to do is just check the option of Install iPad Baseband

              7. Now proceed next and the work on your iPhone will start.

8.  The process will take few minutes to complete, so be patient.

9. After updating to the iPad Baseband, you need to follow the guide present below to obtain the unlockable Baseband 5.13.04.

  • iPad Baseband Downgrade process:

Once you are on iOS 4.1 or relative iOS of which you had the SHSH Blobs, now it’s the turn to downgrade the iPad Baseband 6.15.00 baseband using Redsn0w 0.9.15b3. The complete guide is present here on downgrading the iPad Baseband.

Step 3:

After you are done with the process of updating and downgrading the iPad Baseband, now comes the turn of final step that’s restoring to the latest iOS 6.1.2 to retain the Unlock and old baseband of 5.13.04.

iphone_3gs_5_13_04_baseband

To do that you need to follow this guide of Sn0wbreeze present here.

If you don’t want to follow this lengthy process, then wait for Redsn0w to get updated. Once Rednsn0w is updated with the support of iOS 6.x.x, all of these complications would end and you would be able to downgrade and update the baseband without any hustle.

    Hi just updated my old 3GS as it was still on iOS 4.1 and most things now require 4.3 at least so I updated to 6.1.2 and was going to use evasi0n but as I only use this phone as a iPod and it was second hand I have no idea who the original service provider was and can’t activate the phone to re jailbreak help please?

    • Daudi

      You need to downgrade the iPhone back to iOs4.1 and then update to ipad baseband, then downgrade the ipad baseband. After that use snowbreeze to make the custom ipsw and then restore to it. U will be on 6.1.2 activated.
      Need further help, so email me at daudi(at)techglued(dot)com.

    you are the absolute best man! I spent hours trying to find a legit way to unlock my phone, and until I found this guide I thought I was screwed. lots of love. :D

    • Daudi

      thanks sir..

  • http://www.facebook.com/profile.php?id=665541169 Manoah Klaasse

    Hi man!! Super, this manual. Thanks!! Perhaps include a way to safely unlock the iPhone? Because that;s not included )correct me if I’m wrong..)

    • Daudi

      Yes. You are right. The only thing needs to be installed is Ultrasn0w. That can be found in cydia. I will update it soon

  • http://www.facebook.com/pasocon.ntcpasocon Pasocon Ntcpasocon

    Daudi, it will work on 6.1.3 ? Thanks

    • Daudi

      Yes. When the jb is out for it.

  • http://www.facebook.com/pasocon.ntcpasocon Pasocon Ntcpasocon

    I mean, mine is 6.1.3 if I follow your tutorial it will work?

    • Daudi

      No it wont work. The downgrading might work.

  • Assad92

    Salam/Hey Daudi, I just followed your tutorial on win 7. I have an iPhone 3GS iOS 6.1.3 with the old bootrom and baseband 05.16.08. It didn’t work out unfortunately, I have the blobs for 6.1-6.0.1-6.0-5.1.1-5.1. Everytime I follow the steps, redsnow comes out with ‘itunes error 1′ when it’s actually almost done restoring to iOS 6.0. Any ideas? Thanks in advance!

    • Daudi

      Walikum Salam. First of all downgrade the baseaband by downgrading the ipsw to 5.1.1 and then follow the steps. It will work.

  • JF

    Hi Daudi,

    I have two questions :

    1 – I have an iPhone 3GS with iOS 6.1.3, baseband 5.16.08, and serial number XX125XXXXXX. Can I downgrade to iOS 4.1 at all? Of course, if I can get there, the rest should be fine, but it’s not clear to me if I can.

    2 – What about the impact of going to the iPad baseband and reverting back to 5.13.04? Will this process hurt my GPS?

    Thanks!

    • Daudi

      You can downgrade to 4.1 anytime.

      First of all make sure that ipad baseband is supported. The impact of going to ipad baseband will loose gps and going back to 5.13 baseband will regain the gps back.

  • Chem

    Hi Daudi,

    I have followed your steps to downgrade the baseband to 06.15.00 and iOS version 5.1.1

    Now my iPhone 3gs connects the SIM to my company thanks to Ultrasn0w 1.2.8 but every one or two weeks it loss the service, then I get it back turning off and on but the last time it didn’t work. This time I had to downgrade the baseband to actual state and at this moment its working properly. My question is, do you know way this happen?

    Thank you very much in advance

    • Daudi

      hello chem,

      first of see for the updates in Cydia and to fix this issue, try to re-install ultrasn0w. people have reported that doing this fixes the issue.

      if this doesnt works, try to reset the network settings and then see..

  • Armando

    Daudi, Excelent tutorial. I am reading from Switzerland. I have followed all your steps. I have right now iOS 4.1 and bb 5.13.04. I need to upgrade iOS, but my question is, there is another way to do that without snowbreeze, i don’t have windows. I tried with redsnow but is asking blobs. What do you suggest? Thanks.

    • Daudi

      unfrotunately there is no way other than sn0wbreeze. redsn0w isnt updated yet

  • Rubik

    hi Daudi!
    what if i have all time 3194 error, and any shsh saved form my locked 3gs.
    i did downgrade to 4.1, and update and downgrade iPad BB. now im ready with my fresh cooked Custom IPSW 6.1.2 which contain UNLOCK option . but iTunes is making all time this 3194 problem. i have tried with hosts file and seperate pc but no diferrence.
    im angry at myself, becouse i GOT THE 6.1.2 before all changes, and FORGOT to save shsh then.. arghh
    i know with tinyumbrella it could be much easier..

    Do you have any sugestion for me? Is it posiible to take shsh from another iPhone?

    • Daudi

      you cannot save the shsh blobs of other iphone and use them. you can see if the shsh blobs are saved in tiny umbrella or not.

  • DKK

    hello Daudi
    I had a problem with my iphone 3gs 16gb, and I do not know whether it’s the iphone or the SU FU
    my iphone now is conditions like these
    -> Iphone 3gs 16gb
    -> IOS 6.1.3 the last time I restore
    -> I’ve jailbreak my iphone
    -> Baseband 5:16:08
    -> Wifi and bluetooth can not be detected
    -> Simcard was also not detected
    -> Often restart by itself

    my question is like this:
    -> Can I downgrade iOS with iOS 4.1?
    -> Can I downgrade the baseband to 5:13:04?
    -> Or what steps should I take?

    I really hope you can help me to fix this iphone
    Best regards
    Abdul Rokhim of Indonesia

    • Daudi

      Hello Abdul, the problem you are stating seems to be of updating to the iPad Baseband that is not supported or updating to the ipad baseband was interrupted. Is IMEI there or not showing up?

      And yes you can downgrade to iOS 4.1 because Apple is still signing iOS 4.1 SHSH Blobs for iPhone 3GS

      • Abdul Rokhim

        soo,my iphone is not totally damage right?
        I seem IMEI can be viewed from the sim card, is it true?
        This includes good news for me after hearing my iphone can be fixed.
        so what are the steps I need to do???

        • ghostadmin

          can you see imei from the settings>general>about?
