Redsn0w 0.9.14b2 downgrade from 06.15.00 to 05.13.04 baseband on iPhone 3G/3Gs

Redsn0w 0.9.14b2 features a baseband option for /3Gs users who are on the iPad baseband. This baseband notoriously causes loss of GPS functionality, so users will now be able to to , another compatible baseband, so that they can unlock and have GPS.

DOWNLOAD:
Redsn0w 0.9.14b2 - OSX | Redsn0w 0.9.14b2 - WIN | Current iOS FIrmware - GetiOS

Step 1: Download Redsn0w and the current firmware version you are running from the links above.

Step 2: Open Redsn0w and go to Extras>Select IPSW and choose the firmware file you downloaded in step 1. 3Gs users with the new bootrom can allow Redsn0w to fetch the firmware files but it is recommended that they perform the first 2 steps as well.

Step 3: Turn your device completely off. Hold the power button until the "slide to power off" switch comes up and shut it down. It is very important that your device is turned off when you initiate the process to avoid issues.

Step 4: Go back to the main screen of Redsn0w and choose the Jailbreak option. When you get to the options screen check the "Downgrade from iPad baseband" option. If you are jailbroken already, be sure to uncheck the "Install Cydia" option. If you are not already jailbroken, you can leave that box checked. Click next and enter into DFU mode per the on-screen instructions.

Step 5: Redsn0w will take over from here, you will see the normal Pwnapple screen, please note that once you get to the "Flashing Baseband" step, it will take a very long time to complete(3-8 minutes). You also will not receive any on-screen feedback during this process, do not interrupt the process just let it finish.

Step 6: Once the process has completed you will now be on the 05.13.04 baseband and you will be able to unlock with Ultrasn0w and have GPS capabilities.

For those on an uncompatible baseband other than 06.15.00

If you are on a different iPhone 3G/3Gs baseband that is not compatible with Ultrasn0w, you will first have to install the iPad baseband with Redsn0w and then proceed to downgrade to 05.13.04. Please note that users whose devices were manufactured after the 34th week of 2011 MUST NOT install the iPad Baseband. Doing so will brick your cellular radio and you will not be able to use it as a phone any longer. You can tell when your phone was manufactured by looking at the serial. The 3rd, 4th and 5th digits are the date. The 3rd digit is the year and the 4th and 5th are the week. "135" would be the 35th week of 2011, so anything on or after that serial cannot use the 06.15.00 baseband.

  1. Shax_friends says:

    Regarding the serial number definition 3rd and 4th digits do not always define week. There are some difference between older and newer models. Look for more information http://modmyi.com/content/6753-what-your-iphone-s-serial-number-really-means.html 

    • Shax_friends says:

       This is really good news. Thank you that you immediate corrected it on the text

    • JaeM1llz says:

      The method of determining manufacture date listed in this tutorial applies to all 3G/3Gs devices. The format only changed for some 4/4S devices which this tutorial does not apply to since the iPad baseband can only be installed on 3G/3Gs devices.

  2. TravisBickle says:

    Hi, I have done the whole process correctly but it did not change the baseband…can’t figure out why…

    • Shax_friends says:

       The same happened to my device. When I updated to ipad baseband everything went smoothly, but I downgraded it nothing changed but cellar stopped working and only “searching”

      • TravisBickle says:

        and BTW I can’t re-do the whole thing because Redsnow says the device is “already jailbroken with rocky racoon…

        • Shax_friends says:

           In that case you have to restore custom IPSW  with iTunes and re-do it. Anyway, it is not changing baseband. This is a big problem!!!

          • TravisBickle says:

            the thing that worries me the most is ultrasnow and ultransnow fixer do not seem to work anymore…I sincerely hope we did not brick the bb…

          • thescragster says:

            Try opening Redsn0w and putting your device into DFU mode, this will force Redsn0w to a different exploit to jailbreak. Let us know how you get on.

      • Alin Paun says:

         Hello Shax,

        The same thing happened to me. To fix this problem, i made a clean restore from apple, and afterwards i re-jailbreaked the device with redsnow. A crucial step is to check the “Install iPad baseband” box. Install the latest version of ultrasnow and it will work.Kinda upset that the downgrade didn’t worked for me :(

        Cheers,
        Alin

      • thescragster says:

        Under Settings, General, About, what does it say your baseband currently is?

        • Shax_friends says:

           When I updated ipad BB where thing was OK. Even service was ON. But when I jailbroke and downgraded from ipad BB it did not change BB, plus there is “no service”

          • thescragster says:

            You can also try re-installing Ultrasn0w/Mobile Substrate as this is a solution to some of the problems

    • thescragster says:

      It is possible that the process does not work on the first time due to a false positive. Give it a try again and see if it works this time. Let us know how you get on

      • TravisBickle says:

        Nope, I tried it twice, everything runs correctly but  when it restarts I still have my ipad BB and no service. I tried to reinstall ultrasnow twice and it still search for signal. BTW I have a 3GS on 5.1.1 (previously JB), new bootrom. 

  3. The_god222 says:

    זה עובד נסיתי את זה כל הכבוד על העבודה המאומצת תודה לכם על הכל 

  4. The_god222 says:

    It works I tried it all respect for hard work, thank you for everything

    • thescragster says:

      Thanks for your feedback, glad to hear it worked for you.

    • Allan 1moon says:

      hey guys i have an iPhone 3GS running 6.15.00 and serial starts wid **1392**** can i go head n downgrade?

      • Bandit says:

        no! you’ll fry the radio and brick your phone, **133****** and lower, they used a different NOR chip that year and week your phone was made!
        The third digit is the year it was made, **1******** = 2011 and ***39****** = the 39th week of that production year. your phone is **139****** wich means your phone was made the 39th week of 2011 and they used a different chip. Sorry! I know you asked this 3 months ago, But i hope it helps anyone who might see this Good Luck!, and Be Careful!

  5. When ever i try this on a 4.2.1 3g it just loads a black screen and then nothing

    After downgrading the baseband will you be able to update with stock IOS?

    i lost my signal and my bb cannot be downgrade also..sad

    • Fepasma says:

      I had the same problem and I reinstalled the 6.15.00 baseband using redsn0w (even if it had not downgraded), reinstalled both mobileSubstrate and ultrasn0w and I have my network back. I hope it works for you

  10. Allan 1moon says:

    I have BB 6.15.00 and serial number 139″ can I downgrade my baseband??

    • JaeM1llz says:

      Unfortunately by installing the iPad baseband you have permanently bricked your device, this downgrade will not work on devices manufactured after the 34th week of 2011.

  11. i have done this to the instructions to the letter on 2 iphone 3g with ipad baseband and all i get is the phone going to reboot and then a black screen then nothing just stays like that and i mean its being hours

  14. firepol says:

    I have a 3gs, week 44, already jailbroken, with ipad baseband, and unlocked. At the question I answer “old model”. I wanted to downgrade. I followed the guide. At step4, after entering DFU, instead of seeing the “Flashing Baseband” logo, I get this error: “the connected device doesn’t support untethered options”.

    Update: I answered “new model” when selecting the ipsw. I tried to jailbreak as explained in step4 and it seems to work right now. So in my case, week 44 is the new model.

  15. Shax_friends says:

    Unfortunately, it did not work for me. I am on ios 5.0.1, 3GS with old bootrom, 3 digits of serial number – **935****. Yesterday, I updated my baseband from 05.16.02 to 06.15.00 (service was ON, GPS worked but not fully), then tried to downgrade but unsuccessful, tried different variants, no way. The process goes smoothly but no result.   Anyway, I am glad it worked most of you.

    • Jessjadeisace says:

      i made this mistake and now i get no sim inserted,no signal or gps this shit has screwed my phone right up

  16. marcos says:

    I followed all the right steps many times to downgrade and still can’t downgrade. It shows baseband 06.15.00

    I tried with the 4.1_8B117_Restore and 4.2.1_8C148_Restore ,,,

    what i’m missing?

    thanks

  17. Moviechoir says:

    it works like a charm. unfortunately GPS location is notaccurate. plz help

  18. Seanmorrogh says:

    G3, OS 4.2.1   – I never get “flashing baseband” , just get a blank slightly glowing screen.

    I have waited up to 15minutes, tried several times, on different computers. Still at 6.15

    Any advice?

    • Paulo Freitas says:

      It has happen the same to me.
      I tried more than 10 times… Just the black sreen and no pinneapple…

      •  i also tried like a hundred times..but i finally solved it… downgrade your ios 4.2.1 to 4.1,,,, its better to use a custom firmware..then do the proccess again..it will work like a charm…the only issue is that my gps ain’t that accurate

  19. ian says:

    i have a problem i’m trying to downgrade but when i press the jailbreak option it states that rocky racoon was already used as jailbreak so i cannot downgrade the bb to 05.13 i already restore my phone and uninstall the rocky racoon. please help.

    • JaeM1llz says:

      Unfortunately by updating to the iPad baseband you have permanently bricked your cell radio. The iPad baseband is not supposed to be installed on devices manufactured on or after the 35th week of 2011.

  21. Chris Keegan says:

    Hi.
    I have an iphone 3GS, IOS 5.1.1, Firmware 05.16.05. The serial number has “016” in it which I guess means it was made in week 16 of 2010.  I already used Redsn0w 0.9.12b2 to jailbreak it untethered and indeed it is jailbroken sucessfully (untethered even though I have the new bootrom in my device)

    Am I right in thinking that 05.16.05 is an unlockable firmware under all circumstances?

    Can I downgrade directly to 05.13.04 from the current 05.16.05, or do I have to upgrade to 06.15.00 and then downgrade to 05.13.04 (I think I will not brick the iphone by going to 06.15.00 because it is built before week 35 2011)

    I can see where I can download the latest Redsn0w from, but where do I get the firmware images from? If I gotta to to 06.15 first and then down again, where do I get these 2 images from?

    Also, before I do this, has anyone successfully unlocked a 05.16.05 firmware – I have tried the Ultrans0w 5.1.1fixer followed by the Ultrasn0w through cydia, but it just spends its life searching for a cell signal

    Any help gratefully received – I’m new to all this

    Thanks

    • JaeM1llz says:

      05.16.05 is not compatible with Ultrasn0w, that’s why you aren’t getting signal. If you want to unlock you will first have to install the iPad baseband and then you can downgrade to 05.13.04 if you want your GPS to work. You can download the firmware file from the link right next to the redsn0w links. You only need one firmware file.

      • Chris Keegan says:

        Hi
        Thanks for the info so far and sorry to bother you again
        I clicked on the link to the right of the Redsn0w downloads (the link called Current iOS FIrmware – GetiOS) on this page and it took me to a website called http://getios.com/ where I filled in that I have an iphone 3gs running IOS 5.1.1.
        I was then presented the oppotunity to download a zip file called “iPhone2,1_5.1.1_9b206-restore” from a site called “appldnld.apple.com” (I have a feeling that this is the firmware that shows up in iTunes when I connect my device)
        When I unzip it I get some folders within folders and so on but I cannot see any files from the zipfile ro any of the folders it creates that end “.ipsw” like I was expecting to see in your screenshots.
        Please can you tell me what I have done wrong and how I get the “.ipsw” files.
        You mentioned in your reply that I only needed one image file – I am guessing it is the 05.13.04 image because I can downgrade directly to that from 05.16.05. Is that correct. Or do I need to go to 06.15.00 first and then down to 05.13.04
        Many thanks once again for your help

      • another fcuked iphone says:

        dont do it i did this and my phone now has no gps,signal and a usless ipad baseband this wont downgrade it

        • JaeM1llz says:

          As long as your device was manufactured before the 35th week of 2011 it works fine.

          • Jessjadeisace says:

            no it dont mine is week 30 of 2009 it is now completely useless,no signal,no sim,no gps,ipad baseband that wont downgrade,there was no problems with it apart from it was locked to o2,it had great signal but i wanted to use a tesco sim so i did what was advised here put ipad baseband and thats it fcuked iphone

          • JaeM1llz says:

            So just reinstall the iPad baseband, simple.

          • Jessjadeisace says:

            tried that and still says no sim so far tried reinstalling stock and custom firmware,reinstalling ipad baseband,downgradeing the baseband 3 times one after the other,ultrasnow countless times

          • Jessjadeisace says:

            i did not wantthe shite ipad baseband but this said the only way to downgrade was to install then downgrade what a load of shite

          • JaeM1llz says:

            Yes, that is the only way to downgrade and without the 06.15.00 baseband you couldn’t have unlocked anyway.

          • Jessjadeisace says:

            thanks for stateing the bleeding obvious,i know without installing the ipad baseband i could not have unlocked,but i could have sold it and bought another  allready on tesco,after reading this it gave hope that i could have done it without going through the hassle of selling my phone to buy another as my phone is mint now it is fcuked it will noe see the sim or give ma a signal ,i have tried everything IT DOE’S NOT WORK i have looked at a few sites and 90% of people find it doe’s not work

          • JaeM1llz says:

            The reason the success rate is so low on the websites you are looking at, is because people don’t generally post comments when they are successful, the people who post comments are the ones who run into issues. I have successfully installed and downgraded the iPad baseband on three 3G iPhones and one 3Gs, so it definitely does work.

      • Jessjadeisace says:

        i have just read that a update is coming out on thursday which will hopefully fix it i have tried and tried ,upgrade down grade,custom firmware,5.1,5.1.1,,ultrasnow,mobile substrate etc etc but still no service ,if i switch to airport mode and back the carrier settings come on saying i am on o2 but still no signal,

        • Fepasma says:

          Try reflashing the ipad BB 6.15.00 using redsn0w even if the downgrade did not work. I had the same problem and I did that eventually, + reinstalled ultrasn0w & mobile substrate and I eventually got my service back – I hope it works for you…

  22. Admin Eskipusku says:

    I just downgraded from 06.15.00 to 05.13.04 successfully. My device is  unlocked with Ultrasnow, however, I still have GPS connection problem. Any help is appreciated.

  28. Chris Keegan says:

    Hi
    I wonder if someone could tell me what I am doing wrong. I’m quite new to IOS. Where do you get the .IPSW files from? I clicked on the link on this page about getting the latest files (the Get IOS link), I entered my phone and IOS version, it downloaded a zipfile. When I unzipped it I got some files on my PC – some with a .DFU extension, some with a .IMG3 extension, but absolutely nothing that ends with .IPSW. The instructions here definately show step 2 opening a .IPSW file but where do I get it from.

    Also on this, are the basebands included in the IPSW file. So for example I have IOS 5.1.1 – will all the basebands that are compatible with this (i.e. the 05.13.04 baseband) be included in the IPSW file. How do I choose the baseband I want – I don;t want it to install 06.15 for example. Are there some extran propmts from those screenshots shown here that when you click on “downgrade baseband” you get to choose the baseband you want to install??

    Many thanks for the help

  29. sixsedred says:

    same here. downgrade doesn’t work and lost signal too.. had to reinstall ipad baseband (even if it’s already shown) then reinstall mobile substrate and ultrasnow just to get signal back..

  31. seem to have gone quiet on the 0.9.14b2 downgrade,for those of us that took the advise and installed the bloody ipad baseband in order to downgrade only to find that 0.9.14b1 did not work we are very much looking forward to it is there any news on when it will be released ,there is nothing on twitter or facebook

    • JaeM1llz says:

      Hi Sarah, unfortunately the latest update was that MuscleNerd’s delivery of the iPhone he was going to test on was delayed. You do have service, even though you are on the iPad baseband, correct? Hopefully MuscleNerd will get the delivery tomorrow and it will be a quick fix and he can release it before the holiday.

      Great – glad to see it works for you.

      I asked this question on the general forum but got no answers and I was wondering if you’d be so kind as to help me out.

      • go to where you downloaded the file,left click and scroll down to rename,delete the zip only and rename ipsw hit enter ,pop up box will say file may be come unstable if file name is changed, change anywhere you will now have a ipsw file not a zip this is if you have a windows pc not a mac,itunes will not install a ipad baseband to preserve the 05.13.04 baseband open redsnow choose custom ipsw choose the ipsw you want let it do its thing ,when finished open itunes shift and restore and choose your custom ipsw for eg no.bb 5.1.1 and let it restore this will preserve your baseband otherwise itunes will update the baseband,most firmware downloads are downloaded as zip files they just need renaming

    • JaeM1llz says:

      This has nothing to do with upgrading/downgrading firmware. If you have a 3G you should be on 4.2.1 which is the latest firmware for that device and supports an untethered jailbreak. There is no reason to be on any other firmware.

      If the device was manufactured on or after the 35th week of 2011, I am afraid you have permanently bricked the cell radio now and there is no way to reverse it.

  52. Anne says:

    Hi what about a 938? do you consider before or after?

    • JaeM1llz says:

      938 means 38th week of 2009, so you are well before the cutoff and can feel free to upgrade/downgrade to and from the iPad baseband.

    my iphone 3gs was unlocked with 6.15.00 i switched to AT&T and now i have 05.13.04 and i am not getting service please help

    • JaeM1llz says:

      If you’re on AT&T you need to uninstall Ultrasn0w, AT&T is an official carrier so it will not work with Ultrasn0w installed.

    Heres what i did and it worked Perfect for me.
    Used the Redsn0w 09.14b2 on 3GS, that was already jailbroke and unlocked on IOS 5.1.1 with the ipad BB 0.6.15 BB.
    What i did was first downgraded from the IOS 5.1.1 to the stock IOS 4.1 which left me with the 0.6.15BB( as BB remains the same) . I then opened Redsnow 09.14b2, selected IPSW 4.1 and hit jailbreak. when the screen came up, i picked downgrade BB only and then allowed the program to reflash to 05.13.04BB. Then i created a custom IOS 5.1.1 ( NO BB) using Redsn0w and loaded that to phone. Once that finished , i opened Absinthe2.04 and jailbroke /installed cydia. Then ran cydia and used Ultrasn0w to unlock.
    the only reason i downgraded first from the IOS 5.1.1 first to the 4.1 is because i read that many people were having problems trying to roll back the 06.15BB when they were on OIS 5.1.1. I did not have any issue rolling the BB back to the 05.13.04 when i used the 4.1.
    hope this helps..

  63. Bandit says:

    ok, my phone was at one time on 06.15.00 and i did the downgrade not knowing the other steps with the ipsw and now my phone is on 05.16.05. now do i have to upgrade to get it to downgrade to the 05.13.04 or just follow the steps in the same way? Or will the ultrasn0w work with the baseband i have now?

    Dear All,

    I have iPhone 3GS with serial number 85947XXXX, i used this process to downgrade my baseband from 6.15.00 to 5.13, it happened successful but then i lost the network. I removed and re installed Ultrasnow but didn’t work, and then i tried to upgrade back to 6.15.00 but still its not working.

    My iOS is 5.1.1

    Please, guide me to make alive back my iPhone.
