Here’s a simple way to do it. I’m fed up with all the comments and emails about this, so I thought I might as well write something up and just point people in that direction. So, here’s the way to do it with a 10.4.x machine, maybe even PowerPC machines.
So, you’ve followed a downgrade guide to the very end, you’re about to use RecBoot and bam, it isn’t supported. It won’t be supported either. So, you panic and email me. I have at least a thousand emails asking exactly the same. So here’s your answer. Hell, in an attempt to explain everything, I’m going to include screenshots.
Download RecBoot Intel (209830), unzip and you’ll find two applications, RecBoot Exit Only and RecBoot. We want RecBoot Exit Only, herein known as RecBoot.
So you’ve got RecBoot and it isn’t supported by your Mac, you panic. You right click on RecBoot and you then click on Show Package Contents.
Wow. Double click the Contents folder and now we have a few more to pick from.
Double click the Resources folder. See that little Terminal Utility over there, the one called iRecover, you’ll need that. Make a copy of it however you want and paste it onto your Desktop for easy access.
So, open up Terminal. This application is the most amazing one known to man, it is, incredible to say the least. Anyway, back to what we’re doing. Type “cd /Users/~/Desktop” without quotation marks. The “~” being your current username. So, now you’re inside of the Desktop folder. Next we’ll want to start up a shell connection with your iPhone, iPod Touch or iPad. OBVIOUSLY THEY HAVE TO BE CONNECTED AND IN RECOVERY MODE.
So we type the following into the Terminal. “./irecovery -s” without the quotation marks. This brings us to a shell created via USB with your connected iDevice. The following gets tricky, so pay attention completely and please, if you have any comments, Google for the answer first!
The rest I’ll do in screenshots so as to make sure you do not get it wrong. It is impossible to do something wrong when it is shown to you, right?
1.
You’ll see this if you have successfully connected to your iPhone or iPod Touch.
2.
Type “printenv” without the quotation marks and hit Return.
3.
Type “setenv auto-boot true” without the quotation marks and hit Return.
4.
Type “saveenv” without the quotation marks and hit Return.
5.
Type “reboot” without the quotation marks and hit Return. Your iDevice will now be kicked out of recovery mode on reboot. Have fun.
And there we have it. No more emails.
