Iphone upgrading to firmware 1.1.2

While the jailbreaking and unlocking of your sim is easy as pie when you have an iphone using firmware 1.1.1, upgrading to firmware 1.1.2 can be a whole other can of fishy noodles. The process involves prepping your unlocked and jailbroken 1.1.1. iPhone and then upgrading to the latest 1.1.2 version, and then running from your mac or pc the jailbreak software for 1.1.2, which will flash it again.

It seems that most upgrade guides are particular in their wording, and if you have the ‘malchance’ to not exactly have the same files on your phone as the one providing the guide, you can be up in shit creek for several hours. I know I was.

I upgraded from my jailbroken and unlocked 1.1.1 firmware to 1.1.2 by downloading the new jailbreak program from Conceited Software, which in its latest version includes ‘hactivation’ of the sim. Or so they state, and for most people it’ll probably work (as read on several forums), but for me only the jailbreak part worked, minus the sim activation.

After much, MUCH, MUUUUUCH trial and error and repeatedly going to back to firmware 1.1.1 (thank god for that) I found out that I needed to perform two extra things while preparing for my upgrade to 1.1.2 :

  • take my sim pincode off – this probably blocked my update somewhere
  • unlock using anysim 1.2.1u (not the one in the installer list, that is not the latest one at current date)
  • and only then running oktoprep in the installer.app
  • and finally upgrading to 1.1.2 firmware, and then running the jailbreak software for 1.1.2

Phew. Was it worth it ? I’ll need some more time to check it out again, while I’m installing all my third-party programs again…

PS – if you want complete guides to hacking your iPhone, I can recommend this site.
