Downgrade iPhone 3G baseband (any) to 2.28 with 3G Fuzzyband Downgrader

A few weeks back, we wrote a step-by-step iPhone guide on How to Downgrade iPhone 3G (2.2.1) Baseband 2.30 to 2.28 for Unlock. That guide let you downgrade iPhone 3G baseband 2.30 to 2.28. But there are two limitation to that guide.

  1. Your iPhone 3G Bootloader version must be 5.08.
  2. You need to go through some technical command lines to check the bootloader version of your iPhone.

3G Fuzzyband Downgrader, developed by w1kedZ (coding) & DHowett (GUI), has taken care of the second issue. Fuzzyband Downgrader comes with one click method that itself checks your iPhone bootloader version without requiring any command lines from user end. User just need to press a button  and it will check iPhone Bootloader version and if it’s 5.08, then you can downgrade Any Baseband ranging from 2.30 to 4.26.08 (beta 5).

Modmyi explains the way how the tool works:

  1. It verifies your bootloader version and displays it before attempting to downgrade (won’t attempt if bootloader isn’t 5.08) so it is much safer than other methods.
  2. It detects current baseband version, and the patches accordingly…this means it will downgrade any baseband from 2.30 to 4.26.08 (beta 5)
  3. It is available now on the BigBoss Repo. Look for 3G Fuzzyband Downgrader.

Have a look at screenshots to know how simple it is:

You can get 3G Fuzzyband Downgrader from Cydia. So, for the purpose, your need to Jailbreak iPhone 3G.

Usual warning applies: Use at your own Risk. We havn’t tried this but if you’re adventurous and going to give it a shot, we would love to listen your experience with 3G Fuzzyband Downgrader.

If you find yourself lucky having Bootloader 5.8 and have successfully downgraded iPhone Baseband, then you can use the following guide to Unlock iPhone 3G:

all these great tools why not one for bootloader 5.9.the majority of people looking to do this have 5.9 bootloader.can we expect one for this?

All these great tools are based on the exploit found by GeoHot in Bootloader 5.8. So works for 5.8 only.

Like you and many others, we are also waiting for a hack into 5.9.

it works!! i used this program last night

David May 23, 2009, 3:25 pm

Yes, we can get this downgrader from cydia but only when phone is connected to wifi. Where is a solution whereby you can get this 3G Fuzzyband Downgrader with no wifi or network connected.

Corey May 25, 2009, 9:43 am

Can’t wait until someone figures out how to go from 5.9 to 5.8

Dan May 31, 2009, 10:15 am

Yea definitely need a 5.09 downgrader, because my sim works with the turbosim for like 2 minutes and then it requires a network reboot which can be frustrating after a while as u cant get any txts and any calls. So any expected time when someone will hack it?
