[iPhone] HowTo Jailbreak and Unlock using RedSn0w

3 Replies

I. Abstract

The following article will show you how to install firmware 3.0 on your iPhone 2G by also allowing to jailbreak, activate and eventually to unlock (JAU process). At the moment of writing this article is for Mac OS X users with iPhone 2G’s only.

II. Who needs this article?

We suppose 50% of all 2G users around the globe. As iPhone 2G’s were sold almost everywhere with Sim-Lock enabled (besides some T-Mobile Germany or Orange France unlocked 2G’s).

III. Warning

You’d better read all of this in detail before you do anything practically! If you feel there is something you don’t understand or something you will not be able to handle, then go and ask someone who is in the know.

!!!!!!!! Otherwise your devices may be terribly screwed up! !!!!!!!

IV. Required Downloads

Download these tiny things first:

» RedSn0w for Mac OS X…
» iPhone OS 3.0 for iPhone 2G…
» if you are using an iPhone 2G: get Bootloader 3.9 and 4.6…

RedSn0w is almost the same as QuickPwn was in the ancient days of iPhone firmware 2.x

V. Preparing for Take off

  1. you need to have iPhone OS 3.0 already installed / updated /restored via iTunes
  2. install RedSn0w
  3. start RedSn0w

  5. Wait for the firmware to be checked

VI. Fasten your seat belts // Get into DFU mode

  1. Click Next
  2. bring out beloved jesus phone into DFU mode
  3. RedSn0w guides you thru the required steps (anyway this may take several repetitions as this is not as easy as some people write on the net!)

VII. Ignition sequence start

  1. the uploaded modified ramdisk will do all the required stuff
  2. to indicate what is going on your iPhone will show some nice pictures like this:
    restoring.jpg
  3. don’t disturb the process
  4. instead: relax and get yourself a good drink or a cigarette
  5. as this may take some minutes

VIII. Possible issues

Although we haven’t been reported any yet, this doesn’t mean there can’t go something wrong. If you run into problems, try:

  • restoring original unmodified 3.0 firmware from within iTunes 8.2
  • make sure you installed firmware 3.0 with iTunes 8.2
  • generate a custom pre-hacked ipsw using PwnageTool (find article here)

  6. The whole process will take some minutes, don’t wonder about that

VIII. Possible issues

You may receive an “unknown error 1600”, “unknown error 2001”, “unknown error 10”, or “unknown error 20” . If this is the case you may try this:

  • restore the original unmodified iPhone firmware 3.0 first and the re-restore your custom firmware and
  • try aswell in DFU mode as in normal mode
  • if all that does not work: restore with original unmodified iPhone firmware and jailbreak with redsn0w (article here)
