  9. hurf27 says:

    Amazing!! I stupidly forgot I’d unlocked my old 3GS and updated to ios6 via itunes this morning. I was sure I’d bricked it.

    For all of the people who are getting the ‘no service’ and ‘searching’ messages you will need to turn off the iPhone and ‘just boot tethered’ via Redsn0w one last time. et voila.

    Also, you will need to ‘just boot tethered’ from Redsn0w every time the phone is turned off.

    Ian, thanks for the help here…. I went through the process and my iphone now see’s the SIM card and I have service. But when I turn off the phone and restart it, I lose it all. I then need to reboot it tethered .

    Is this jailbreak just a tethered jailbreak?

  16. Peter says:

    The youtube lesson says this is an un tethered unlock. So I am wondering still if there is something we are not doing right. I would love if IAN could comment here for us. thanks Ian. How do we make it an untethered unlock…so I dont have to re-run redsnow every time my iphone powers down.

  28. STRdrum says:

    After clicking on Just Boot I do not see the pineapple on my iPhone. it shows missing Keys.plistdats for this build: anyone know what I can do next?

  29. Kleosbet says:

    i see the same problem…. missing keys.plist data for this build 🙁
    please help……

  30. Kleosbet says:

    For everyone with the MISSING KEYS.PLIST ERROR
    1. Exit redsn0w and turn off your phone and unplug it
    2. Plug your phone back in and then enter DFU mode without opening redsn0w yet. DFU=(3 sec lock button, 10 sec home and lock button, 15 second just home button).
    3. Once in DFU mode, find redsn0w on your computer, right click on it and take ownership/run as administrator!
    4. Open redsn0w, go to Extras>>Select IPSW>> select the 6.0 IPSW.
    5. Go back, Jailbreak! let it do its thing and install cydia and then once the jailbreak is done and phone booted on, turn off your phone.
    6. Exit redsn0w, unplug your device, plug it back in and put the phone into DFU mode! Open redsn0w!
    7. In redsn0w go to extras>>select IPSW (6.0).
    8. Extras>>Just Boot>> This is the only fix for the missing keys.plist error!!


  31. sawa says:

    i’m getting a blank screen when i boot tethered..please help what to do next??

  32. Venkat says:

    After jail break, these fixes solved my issues
    1. For Missing keys.plist data for this build: Restart PC, start redsnow, select IOS 6.0 Firmware File, Just Boot will work now as described above

    2. Even after “just boot” process succeeded, no service problem remains. FIX: Again do JUST BOOT from redsnow as described above. Then Network will be detected and that saved my day and Iphone.


  33. Danny says:

    I keep getting a “this ipsw is not supported by this version of redsn0w..”

  51. Helen says:

    i had a battery replaced on 3gs and now i have no service or searching… but when i take the simcard out, the phone says no sim. should i still do this process to fix the phone or does something else need done? thanks

  54. Rue says:

    Doing these steps, I get to the 5:43 mark in the video (rebooting) but I get an error in Redsnows screen, this is the error I get…

    Missing Keys.plist data for this build:

    Device: iPhone 3GS
    ECID: 3370577221071
    Build: iPhone2,1_6.0.1_10A523

    I also looked on my iPhone and Cydia was NOT installed, is there another way to install Cydia?
    Any advice on how to fix this?

  55. godwin says:

    hi there just wanted to know if the no service/ searching fix applies to ios 6.1???? thnx

  56. jimi says:

    How do I determine from my serial number if I have an old or new bootrom? The description within redsnow after I click to choose IPSW a message box appears asking if my 3GS is a new model or not coz I have to determine if I have a new or old bootrom. The method is just not very clear. Please, any smart person out there, a little help. I’m about to give up on the phone and just turn it into a paperweight lol.

    Also, I’ve been stuck on the “cannot activate the phone because the server isn’t available”. I’ve tried jailbreaking, downgrading, restoring to another IPSW, nothing worked. Incidentally, the redsnow I downloaded from Ian’s link wouldn’t recognise the IPSW 6.0 or 6.1. Where to go from there? If I’m not gonna be good enuff for this phone, then iPhone isn’t gonna be good enuff for me.

  57. jimi says:

    Incidentally, there are other sites that say “no activation, no jailbreaking” and one cannot install cydia either without the first two I just mentioned. WHAAAT??? So where to go from there?

  58. alpha says:

    hi, thanks for all your idea it really work but after have jailbreak my iphone3gs and install cydia following all your steps on how to install ultrasn0w and ultrasn0w fix. am still unable to get signal of my phone.please what can i do.

  59. Helppls says:

    I cant add the repo because it is legacy but I did downlload ultrasn0w without fix and I can call but cant text. What do I do?

  60. John says:

    Hi, I downloaded all the files but in my desktop dont have the option of the 3GS firm file like yours, when I open redsnow I dont get the same icon that you have on the Firm File… what am I doing wrong.


  61. david says:

    hi Ian, i followed your instruction, did everything as told. and now i cant send sms messages, it says “failed”. my iMessages is off, and still no sms sending.
    what can be the problem? maybe another cydia package missing?

    tnahk you very much,

  62. etienne says:

    Thanks Ian you’re my god for now on !

  63. ThaiWockeez says:

    1. Exit redsn0w and turn off your phone and unplug it
    2. Plug your phone back in and then enter DFU mode without opening redsn0w yet. DFU=(3 sec lock button, 10 sec home and lock button, 15 second just home button).
    3. Once in DFU mode, find redsn0w on your computer, right click on it and take ownership/run as administrator!
