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.

Installation Notes

Tips to solve common problems during and after Linux installation.

For multiple partitions:

“Guided Partitioning” is a tool that needs to take advantage because it does some of the job for you. My favorite method is to free a partition in Windows (shrink) and later during Ubuntu installation use “Guided – use the largest continuous free space“
