This Guide is For iPhone 3G

These are instructions on how to Restore And jailbreak your iPhone 3G on the 4.2.1 With Custom Firmware (if You Already Have 6.15 Baseband)


IMPORTANT FOR UNLOCKERS
During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this.

1-Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail). You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).
2-There are reports that 06.15 may disable your GPS. The iPhone Dev-Team is currently working on a fix.

Don’t update to 06.15 if you don’t need to! Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.

These are instructions on how to downgrade your iPhone 3GS or iPhone 3G's baseband from the iPad's 06.15 baseband to 05.13.04 using RedSn0w for Windows.

Typically you’d have the 06.15 baseband if you unlock with ultrasn0w but updated your iPhone baseband past 05.13.04. With this new capability, you can now downgrade specifically from 06.15 to 05.13.04 (even if you never had 05.13.04 on that device before). This gives you the best of both worlds: ultrasn0w unlock compatibility and a normal iPhone baseband with full GPS and the ability to use stock IPSWs again.

Download Latest Redsn0w From here [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذا الرابط]


Step One
Create a new folder on your desktop called Pwnage.[Optional] Or Just use Redsn0w Folder After Extracting it


Step Two
Once RedSn0w opens click the Extras button.


Step Three
Choose Select IPSW from the Extras menu.


Step Four
Navigate to the Pwnage folder on your desktop, choose the firmware ipsw we downloaded earlier, and click Open. (4.2.1 For iPhone 3G Original IPSW Not CFW)

Step Five
Press Back to get back to the main menu then click the Jailbreak button.


Step Six
Check the Downgrade from iPad baseband checkbox, uncheck Cydia if you already have it installed, and click Next to proceed through the normal DFU ramdisk steps.



After showing some scrolling text, your iPhone will display the pwnapple icon and say Flashing Baseband. THIS STEP TAKES A VERY LONG TIME to complete and there won’t be any feedback while its running. Please just let it be for the next 3-8 minutes! When the ramdisk has done its job it will reboot the phone on its own.




How to Enter DFU

If You Get ERROR! in the Middle of Downgrade Process
Restart Your Phone By Holding Home+Power And After The Phone Open Completely Power Off The Phone Normally (Slide to Power Off) And Then Enter DFU And Try again
