1.1.2 & 1.1.3 OTB 16GB iPhones Easiest Free Software Unlock : Noob’s Guide!

9 February 2008 69 Comments

Update : A much faster easier solution for Mac users can be found here. Windows users may resort to ZiPhoneGUI.

I am back after spending 4 hours on the entire process (which includes some hits and misses! Which means, you no longer have to figure out the right steps/combinations!!). Now the process is trimmed down to much lesser time and the best part being : No command line hackery!

All you need is an iPhone (OTB 1.1.2/1.1.3 BL 4.6), Mac (preferable) / Windows, Firmware files (1.1.2, 1.1.3 ipsws), courage to try this all on your pricey iPhones 🙂 (Trust me, it is so easy!!). Please note I used the ATT sim that comes with the iPhone all the way till the iPhone is unlocked.

I am performing this Unlock on a brand new 16gb iPhone that cam out with 4.6 BL and 04_03_13GB BB. Please proceed with his guide only if you have an OTB 1.1.2 or 1.1.3 with 4.6 BL.

UPDATE : After trying this method for one full day, I had some issues with 1.1.3 Dev Team’s soft upgrade. I had no problems restoring it to 1.1.2 and the Unlock sustained just fine. Hence, I recommend using 1.1.2 until a stable 1.1.3 is achieved.

Step 1 : The most important and tricky one : Downgrading OTB 1.1.3 to 1.1.1 (From _BigBoss_)

  • Turn your iPhone off and hold the power and home buttons for exactly 10 secs (yeah count them!).
  • Now, release the Power button still holding the Home Button till iTunes prompts this message ( you get a beep sound both on PC and Mac ). Remember that the display doesn’t show up at any point.

If you have come this far, you have completed the tough part, now for the time consuming sit-back and let-it-perform part!!

Step 2:

Make sure you have 1.1.1 and 1.1.2 firmware files downloaded. Now hit the ‘Ok’ button on the iTunes prompt and hold the opt(Mac)/shift(Windows) key and hit the Restore button. Now locate the downloaded 1.1.1 Firmware file. Wait for it to restore and repeat Step 2 one last time! Yeah, I had to do it twice. First time, I couldn’t kick it out of the restore mode after the iTunes performed the restore process. Hence, I recommend performing the Restore process once more 🙂

Step 3:

Time for famous WiFi Jailbreak process, thanks to Jailbreakme.com! Follow the process here if you are yet to memorize it!!

Step 4:

Don’t worry about any weird SIM error messages till you reach the last step! Now another routine method, OktoPrep Jailbreak 1.1.2 which is detailed here. So, you now see 1.1.2 iPhone HomeScreen. If you still see the Plug icon (DFU mode) then Lunch iBrickr/ iNdependence to kick the hell out of the DFU mode!!

Step 5:

Now comes the 1.1.3 SoftUpgrade process. Remember not to perform 1.1.3 iTunes upgrade as some did which takes us back to Step 1!! iClarified really detailed this step. It involves adding iClarified repo in installer.app (add source : installer.iClarified.com). Dev Team 1.1.3 SoftUpgrade process takes a minimum of 30 minutes. So be prepared.

Step 6:

So now comes the best part : Freeing your iPhone for any network in the world. Time to use Geohot’s most famous, completely free Software Unlock.

Make sure you set General -> Auto unlock -> Never.

Now Launch installer.app -> iClarified -> Geohot Unlock (1.1.2, 1.1.3) -> install. It should take not more than 5 minutes to free your iPhone! Congratulations – You have successfully unlocked your Apple iPhone!!

Snapshots of the unlock process at iClarified’s detailed post

Install iWorld from installer.app -> Tweaks 1.1.2 to prevent phone/sms crash. iWorld supports only few carriers. If you are still facing phone/sms cras, rush to iClarified to resolve this issue 🙂

Few Observations :

  • Sound seems lot better on 16GB iPhones !
  • This method doesn’t fix Google Maps faux-gps solution. Locate Me is still needed from istaller.app to guide the mighty ‘Google Maps’ !!
  • *SIMS will soon be offered for peanuts, trust me eBayers rush your orders before its too late !!

A video compilation of some important steps in the process is underway. Check back soon!!

    I got a new truble! i downgraded it to 1.1.1 then i jeilbrokek it, after i downloaded anothe firmware(1.1.2, i think it did not work before because i was using bad or corrapted 1.1.2) now it worked.
    After i jailbroke 1.1.2 i used (ibrickr jb113), and i folowed its instructions. then i downloaded upgrade from installer on the phone.
    Now i have working and jailbroken 1.1.3 but it does not recognise any sim even original ATT. It doesnt show eny errors but i can not call nor can i receive any calls. Please HELP!!!

  • kiran said:

    @ Master : Cool, I performed the above method on a 16GB iPhone! Hence you should follow the steps exactly!! I also used iTunes 7.6 in the process. Please check my video too.. Trust me, it should work!

    @ Yuriy : You won’t get a signal in 1.1.3 unless you unlock it as described in this post. It is a known issue, you have to unlock to get the signal!!

    hey, i followed the directions exactly, but everytime i restore to 1.1.1 i always get error 1015. did you get that too? if so, what did you do to get around it?

  • Hassan said:

    My iphone says NO-WIFI, help please

  • kiran said:

    @ Rod : 1015 is normal. All you have to do is launch iBrickr (Windows), iNdependence (Mac) to kick it out of the restore mode.

    @ Hassan : I am working on such a device (BL 3.9, Modem formware : 4_02_13G). lemme know your device specs too..

  • Nick said:

    Sorry to noob it up guys, but when I download 1.1.1 my computer automatically unpacks the file. Should I create an archive of it to return the file to a .zip or do I use a specific file in the folder to restore it?

  • Kyle M. said:

    Is this possible with 8 GB phones?

  • Jack said:

    Hi guys,

    When I try to restore the 1.1.2OTB 8GB iPhone to 1.1.1 I get an error says
    ‘The iphone “iPhone” could not be restored. An unknown error occourred(1015).’
    Any ideas as in why?


  • kiran said:

    @ Nick : We are looking for an ipsw file for restore purposes. Unzip the archive and check for the ipsw file 🙂

    @ Kyle : Yep, it is very much possible with 8/16GB iPhones!!!

    @ Jack :

    I have gotten to stage where I would like to jailbreak oktoprep for 1.1.2 but it’s gone… now you see 1.1.2/1.1.3 OTB…..But there seems to be problem, it does not load to phone…It gives a error message… I’ve tried so many times that I lost count.
    Does anyone have a solution? Thanks… For now I’m stuck in ipsw 1.1.1 though everything works fine….But I would like to go on

  • paul said:

    Hey ppls, Does anyone have trouble w/installer app..1.1.2/1.1.3..Such as error message “main script execution failed”.. If so are there any solutions to the problem? Many a thanks

  • paul said:

    Hello Again….I’ve gone as far as restoring ipsw 1.1.1 and yet can not seem to prep the phone for ipsw 1.1.2 because the installer package won’t execute and there is no point of going on without it. I have a 8g iphone…Anyone have a solution or a fix……..many a thanks

  • Nick said:

    When I try to unlock my phone with anySIM (when it is copying the firmware), it brings up a message that says, “Please restart your iPhone anySIM cannot unlock this phone. anySIM will now quit. Please turn off your phone and turn it on again after anySIM quits”. What should I do?

  • PAUL said:

    What is 4.6 BL ?? and where to you find it?? also why can’t this process start from 1.1.1 in the fist place?

  • kiran said:

    @ Paul, Polo, Nick : Please try http://ilikemyiphone.com/wordpress/?p=164 if you have a mac or else, we can proceed further with the current method on this page. 4.6 BL is on all the OTB 1.1.2 and 1.1.3 iPhones. It can start from 1.1.1 but now using a new process, you can even start from 1.1.3!!
