Fuzzyband Downgrader detects your bootloader and baseband and downgrade it with a simple click if your bootloader is vulnerable to Fuzzyband . Fuzzyband Downgrader available in Cydia, just refresh your sources and search for Fuzzyband and install the application. But you need to do little more effort with fuzzyband and following are the step by step instructions.
Please Note :
- Downgrading works from any version greater than 05.13.xx It will put your baseband back at version 05.13.xx which is hackable by ultrasn0w.
- Downgrading only works on iPhone 3G with 05.08 (5.8) Bootloader from the factory. This is a very limited number of phones that were released in the first few weeks of the 3G production cycle.
- If you do not know your bootloader then you can run Fuzzyband and it will report the version number for you.
- iPhone 3GS and large numbers of iPhone 3G aren’t supported by the Fuzzyband, so in case your baseband is updated then wait for Dev team/GeoHot to release any workaround. This may take weeks or months.
- iPhone 3G Jailbroken
- Fuzzyband installed via Cydia;
- afc2add installed via Cydia;
- iFunBox (for Windows) or DiskAid (for Mac);
