If you are reading this guide, it means that you, as me, as well as many others got stuck at some point. iPhone OS 4 is nice and it really have some new and very useful features, but than again, what features are good for if the device is impossible to use? Until Apple will release a reliable firmware 4.xx for iPhone 3G you can downgrade the firmware to one that enables you to sent messages, make phone calls, read mail, write notes.. you know , the things for what you bought your iPhone in the first place.

So what will this guide explain?

- Slow iPhone 3G iOs 4 solution
- Downgrade iPhone 3G from firmware 4 to 3.1.3
- Restore error in iTunes code : 1601, 1602, 1603, 1604, 1608, 1609, 1611, 1612.
- Restore error in iTunes code : 1002, 1011, 1013, 1014, 1015.
- In-out Restore Mode using RecBoot
- Redsn0w is unable to recognize the 3.1.2 or 3.1.3 firmware.
- Cydia error : apt.saurik.com host unreachable.
- Saurik repository : dev-team repository to Cydia (repo666.ultrasn0w.com).
- Accessing iPhone as root solution

First of all, and very important : Save (write down) all your important data like:　contacts, notes, mail, SMS. It is impossible to restore the iOs4 backup to the 3.1.3 firmware. Be warned of the risk of losing your data and act accordingly. Yes, you can restore back iOs4 or 3.1.3 Back and Forth…and Back Again as many times you need, but than again, that will make you loose time.

The problems began for me with this first step. Here are the correct information regarding the downgrade:

Download the required old ipsw firmware files. (Download links: iOS 4, 3.1.3, 3.1.2)
Put your device into DFU mode (not recovery mode).

* Connect your iPhone to your computer.
* Turn iPhone off.
* Start iTunes.
* Hold Power and Home buttons together for 10 seconds or so.
* Release Power button but keep holding the Home button until your computer recognizes a new USB device.
* iTunes will now recognize your iPhone.

Note: Your iPhone screen at this time should be blank (black in color), if not, then you are most likely in Recovery Mode, not DFU mode.

The solution is correct but you might find yourself in the situation where you cannot restore the phone and iTunes will display one of the errors: 1601, 1602, 1603, 1604, 1608, 1609, 1611, 1612. If you got one of this errors the only way is for you to downgrade iTunes to a version that allow you to restore since the last version ( 9.2.14) will make the same error again and again. I had an old version of iTunes 9.0.3 (you can download from Apple ) already installed on another computer and so was able to restore my phone to the 3.1.3 firmware. At the end of restore process iTunes will give one of the following errors : 1002, 1011, 1013, 1014, 1015. Do not worry , at this step the restore process is complete; Just use RedBoot to kick iPhone out of Restore mode (all about RecBot including links and source code can be found here: iPhone-iPod-iPad-recovery-mod-tool-RecBoot ). If something is wrong pls go to the beginning of the guide and start all over.

Now you will need to exit your device from Recovery Mode. To do this, download a program called RecBoot (Windows / Mac). Run it and the click on “Exit Recovery Mode” button. Your device will now restart normally.

This is it, you should now be able to jailbreak your device on this older OS. For iPhone 3.1.2 firmware, you can use blackra1n, PwnageTool, redsn0w, sn0wbreeze, ultrasn0w and blacksn0w to jailbreak and unlock your iPhone and iPod touch. For iPhone 3.1.3 firmware for iPhone 2G, 3G, 3GS and iPod touch 1G/2G, you can use redsn0w 0.9.3, redsn0w 0.9.4, sn0wbreeze, PwnageTool 3.1.5. Unlocking can be done using ultrasn0w or blacksn0w. iPhone 3.1.3 (on devices with new bootrom and baseband) can use Spirit to jailbreak iPhone 3GS/3G and iPod touch 3G/2G.

Wow… we made it… For a big bunch of you Yes, the journey stops here. As for me and other unfortunate people, the journey just begins . But don’t worry, we’ve figured it all out, and we’ll give you instructions for other problems too.

So here we are, we found another problem : Redsn0w is unable to recognize the 3.1.2 or 3.1.3 firmware. Strange since before (3 mount before) it worked… Something happened in the mid-time but cannot figure out what. I tried with redsn0w 0.9.3, redsn0w 0.9.4 on firmware 3.1.2 and 3.1.3 using Windows Xp, Windows Vista and Windows 7 and with different versions of iTunes installed : 9.2.1.4 and 9.0.3.
So I decided to use Spirit to jailbreak my phone. Follow this tutorial on how to use Spirit to jailbreak iPhone3G.

Here comes another problem and this problem occurs especially for the guys who are in China at the moment of this process (like I am now ) : The Cydia version that gets installed by Spirit is an old version and have some errors making it impossible for you to install anything. While trying to upgrade the essential packages I constantly receive this error : apt.saurik.com host unreachable. I tried to unlock my phone using ultrasn0w by manual adding the dev-team repository to Cydia (repo666.ultrasn0w.com to Cydia. That last “o” is actually the number zero “0”. If you use the letter “o” you’ll get an error). Problem is that there are some dependencies that should be download from saurik’s repo… and here we are again.. impossible to unlock or use my iPhone3G.

I found the solution on the modmyi forum and I will explain how to do it.

the final host file should be like this

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
echo ”
93.184.221.133 cache.saurik.com
”

So in order to make this mod you need to access the file located at /etc/host . And in order to do this you need to be able to root-access your device. So there is a new problem and of course we’ve got an answer to it. The package that gives you root access to your iPhone is named afc2add and can be found in saurik repo ( that you can’t access for the present moment) but also on ModMyI.com repo that is available. It does come with one dependency but that will pose no problem ( at least for me it didn’t). Just follow the picture I attached and go in Cydia and enter : Manage than Sources and than navigate trough ModMyI.com repo until you find afc2add package. Install the package.

Now you are able to access your iPhone at a root level, and you can do this using iPhone Explorer or with Total Comander after installing T-Pot plugin. I use Total Commander on regular bases and for this task too.

This was the final step for me and for all the unfortunate Asian friends that struggle with the same problem. Modifying the host file will allow Cydia to update all its sources, upgrade to the latest version and so unlock your iPhone 3.1.3
I have once again an functional and quick iPhone3G.

I hope you enjoyed this journey and I hope this guide was useful for you. If you find this guide useful, please leave a comment.

As you may have already seen, RecBoot is a utility which allows the user, you, to kick the connected device(s) into and out of recovery mode.

Unfortunately RecBoot for OS X does not support 10.4.x machines nor does it support PowerPC machines. This is due to the fact that I have neither to test with, however, the source code is readily available to those that do want to create a RecBoot for 10.4.x or PowerPC. All I ask in return is that you contact me via email in regards to what you’re going to develop and how this will help. I will also be able to assist in hosting the newly created version of RecBoot.

“This handy little utility plays an important role in finishing off the downgrade.”
- LifeHacker

“In a few seconds, RecBoot would help you out of plug-me-into-iTunes recovery mode and you’ll boot right into your freshly downgraded 3.1.3.”
- FindTut

“The tool is dead simple, and everybody can use it. It has two buttons ‘Enter Recovery Mode’ and ‘Exit Recovery Mode’ , and you don’t have to be a genius to know which one to click.”
- FunkySpaceMonkey

The newest version of RecBoot for OS X can be found here: RecBoot Intel (82957)

Updated.
The above version of RecBoot is 1.0.2. It is a little bit different to past versions and I would appreciate it if you read the README.txt before commenting.

Windows Users
The long awaited update is here: RecBoot no longer requires libusb! The next update to RecBoot would make it interact with MobileDevice.h, and I’ve been chatting with iH8sn0w on IRC on getting this done.

So, here’s the deal: I’ve been getting TONS of emails from people saying that RecBoot wasn’t working for them because of libusb. This update makes RecBoot use iTunnel instead of iRecovery, which is based around MobileDevice.h, which means no libusb!

If you wish to enter Recovery Mode, however, you will need to place iTunesMobileDevice.dll in the RecBoot folder. I cannot provide this due to legal reasons. I could have made RecBoot point to the DLL from the registry, but I’m not going to, it’s just a quick open source thing I created for the community that isn’t a big deal, feel free to do whatever you want with it, use the batch files and everything else in the folder. The source code can be downloaded here. RecBoot is in your hands now.

You can Download RecBoot 1.1 here

Linux Users
No, we didn’t forget you either! Thanks to the magic of @malontop we can now offer you a version of RecBoot for Linux! If you have any questions, feel free to contact him via Twitter. You can download the Linux version from here: RecBoot for Linux (1129)

10.4.x and PowerPC Users
If you’re having difficulties with RecBoot on a 10.4.x Mac and/or a PowerPC Mac, it won’t be fixed. It just won’t be supported at all. So, a detailed “How-To” is available here for you. Hopefully this stops ALL emails wanting a 10.4.x and PowerPC version.

The iPhone Dev Team has just updated PwnageTool to version 4.01, bringing fix for iBooks on iPhone which was problematic on pwned and hacktivated iOS devices running iOS 4. Almost everything else remains the same except for this issue, and so it is recommended that you jailbreak your iPhone again if were having issues with the last release of PwnageTool.

Redsn0w has been updated to bring jailbreak support for the newly released final version of iOS 4 for iPhone 3G and iPod touch 2G. Available for both Windows and Mac, redsn0w jailbreak tool additionally also enables options for multitasking and background wallpapers on iPhone 3G and iPod touch 2G which otherwise are disabled by Apple.

Redsn0w beta has been updated to hacktivate iOS 4.0 for iPhone3G (in addition to jailbreaking the iPhone3G and iPod Touch 2G).

For now, the redsn0w beta release supports only the iPhone3G and iPod Touch 2G at today’s 4.0. It’s still a beta, so you’ll need to let Cydia reorganize, reload, and update after using redsn0w.

Follow the step by step guide posted below to jailbreak your iPhone and iPod touch using Redsn0w.

Step 1: Download iOS 4 (final version) for your version of iPhone and iPod touch. Download links are posted here.
Step 2: Update to this latest firmware using the iOS file you just downloaded via iTunes 9.2.
Step 3: Start Redsn0w 0.9.5b5-3 (download link given below) and point it to the original iOS 4 firmware file to proceed.

Jailbreak iPhone OS 4
Step 4: Now select “Install Cydia” and click “Next”.

Jailbreak iPhone 4.0
Step 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.
Step 6: Connect your device in recovery mode by pressing the Power and buttons continuously.

Jailbreak iPhone 4.0 Beta
At this stage you will be presented with a screen where you will have to quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.

Step 7: Sit back and enjoy while redsn0w will do all the rest for you. Once done, your iPhone and/or iPod touch will restart automatically and you will find it jailbroken on the latest iOS 4 firmware.

If you notice a blank white icon for Cydia with no sources. Go to the Sources panel and add http://apt.saurik.com/cydia-3.7 repo. Now restart your phone and you should see the regular standard Cydia logo with all the sources now.
