Downgrade firmware from 2.0 to 1.1.4

Downgrade firmware from 2.0 to 1.1.4

Downgrade baseband from 4.05.04_G to 4.04.05_G

The mistake basically is to update to iTunes 7.7 because it will installed 2.0 in your iPhone and with this the jailbreak will not work.

Steps

Uninstall iTunes 7.7 ; Install 7.5; Reboot

Put your iPhone in DFU mode which let you upgrade or downgrade the OS. If you see the cable and connect to iTunes, you did not get into DFU mode.

· Attach the phone to the pc

· Turn the phone off

· Hold power and home together for *exactly* 10 seconds

· Release power but keep holding home until the pc beeps as a USB device is recognized.

· At no point will the display come on. Now your restore should work.

1. Restore using iTunes 7.5. You will get an error like 1011, 1012, 1013, 1015. This is normal and expected. An error 1601, 1602, 1600 or anything else is not ok.
2. Once you get error above, leave iTunes open and but cancel the restore mode. It will not work if you try to restore.
3. Now run winpwn and pwning the device at this point. The normal restore still won’t work which is good because it gives you the chance to fix some errors such as in youtube and yahoo email.
4. With iTunes open. Install and run iLiberty+
5. You should be able to use normal restore mode
6. Once completed, you have a pwned device with baseband 4.05.04_G from your firmware v2.0 which no longer exists. Next step is downgrade the baseband to 04.04.05_G. To do this use the Ziphone patch.
7. I recommend just loading winpwn(PC) or pwnage(MAC) and pwning the device at this point. If pwnage fails to work, you need to restore your phone again. You should be able to use normal restore mode, however. Other ways to kick out of restore mode may be ibrickr, jailbreak 1.1.2 (boot phone), iLiberty+.

To know which bootloader version your iPhone has

The easiest method is to see the serial no on back of the iphone. The 4th & 5th digit from starting of serial no will give you the week of release.

The iPhone has great open source applications, which are very easy to install and use. Most of these are free. To jailbreak your iPhone 1.1.4 use Ziphone.

If you made the mistake of installing iPhone 2.0 from iTunes 7.7 check this link

Pros: Availability of tons of awesome, useful, and fun applications

Cons: Yahoo Mail and Youtube will not work anymore. However, these can be replaces by gmail and MixTube which in my opinion are much better. Use iLiberty to fix these problems

Installation of packages

By the default ziphone will provide a repository called Installer which is pretty well maintained with updates, and new programs. Within Installer there is another repository called Cydia. I have found in both excellent results. Cydia is mostly focused on development.

To get the best of the best from these repositories, must check section by section and pick your favorite applications, there is no harm to try them because these can be uninstalled anytime.

Here are the applications I have found very useful:

Customization: Dock, SummerBoard, BigBoss Wallpaper Pack, MacBook Air Keyboard

Media: MxTube, iPhone Video recorder, VoiceNotes, Snapture

Toys: Waves, Drummer, Sketches, Capture

Office: moleskine, MobileFinder

Scientific: HP-11C

Open Source: Community Sources, BSD Subsystem, Term-vt100, OpenSSh

iPhone tips and tricks

Use Nautilus to browse files in your iPhone (must have your iPhone SSH)
In the address bar type: sftp://root@iphone_IP

To might also want to modify icons, these are located mainly in two directories:
/Applications (programs installed)
/private/var/mobile/Library/Webclips (bookmarks added to home screen)
Use GIMP to customize those icons, and make sure their extension is png and the size is 59×59 pixels. To fix the size in GIMP: open the png file, go to Image/Scale Image, and in Image Size fix the Width and the Height to 59
