3G Fuzzyband Downgrader - Downgrade any baseband with a simple click of a button

[kracken]

This wonderful GUI Baseband downgrader was created by w1kedZ (coding) & DHowett (GUI). It is based on the exploit in the 5.08 bootloader found by geohotz. So yes you must have the 5.08 bootloader for this to work. The beautiful part about this tool is that it will check your bootloader for you.

The way 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)

It is available now on the BigBoss Repo. Look for 3G Fuzzyband Downgrader.

How would i check what bootloader i am on before hand? Im on 2.2 firmware now and thinking about upgrading to 2.2.1 and then re-jailbreaking. Is this safe, or will it change the bootloader?

thanks

Run 3G Fuzzyband Downgrader and it will tell you first....

Thanks - i did read that, but what i would like to know is more about the bootloader. For example, im on 5.08 now, but if i upgrade firmware to 2.2.1 what version will i be on then? When does the bootloader version get updated?

Thanks

the bootloader is untouched by software updates. If you have a bootloader 5.08 then you have it forevermore.

Kracken, there's nowt in your picture that I can see that says you can't run this downgrader.

The downgrader is supposed to work fine with bb 4.26.08 - as long as you have bl 5.08 and after you have downgraded to 2.2.1

I just put this on my phone which was purchased on January 1st (from CPW not ebay so current stock at that time) and it showed 5.09 so it's unlikely many will benefit from this.

I have just checked using BBUpdaterExtreme and MobileTerminal and it reports back the following .....

[maltloaf]

apparently 5.08 is the very first publicly released iphone 3G bootloader so will have been all the launch handsets and for a little while after and as I said isn't touched at all by any upgrade process... Whatever bootloader you have, you have for life..

[yus786]

huh so does that mean if i upgrade from an unlocked 2.2 to 2.2.1 it wont upgrade my bootloader so i can unlock it again using yellowsn0w malt?

yus

[maltloaf]

Yes as long as your bootloader is 5.08

[dannoble82]

This will allow you to unlock your iPhone 3G using YellowSn0w.

so if i use this on my 3g phone i will no longer have to use this shitty rebel sim card and i will actually be able to get 3g instead of 2g?

[dannoble82]

just tried it and it says ........

this software will only work with baseband bootloader 05.08,

is there any other software that will work ?
