The following article will show you how to install firmware 3.0
on your iPhone 2G by also allowing to j
ctivate and eventually to u
nlock (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).
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
VI. Fasten your seat belts // Get into DFU mode
- you need to have iPhone OS 3.0 already installed / updated /restored via iTunes
- install RedSn0w
Browse to the downloaded restore firmware (iPhone1,1_3.0_7A341_Restore.ipsw)
- Wait for the firmware to be checked
- Wait for the firmware to be modified
- Select Install
Unlock if you are using an
iPhone 2G. If you are using an iPhone 3G, don't select to unlock, since it will not work this way)

VII. Ignition sequence start
- bring out beloved jesus phone into
- 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!)
VIII. Possible issues
- the uploaded modified ramdisk will do all the required stuff
- to indicate what is going on your iPhone will show some nice pictures like this:
- don't disturb the process
- instead: relax and get yourself a good drink or a cigarette
- as this may take some minutes
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)
