    3.03 fw downgrader has now been released as you probably know ! Here's everything you need.


    Full instructions for downgrading are included in the Downgrader_HOWTO.txt file in the ZIP file. Read them carefully!


    Warning: After downgrading from 3.03 to 1.5, there are some remnants of 3.03 left in flash. If you later try to re-upgrade to 3.03 and repeat the downgrade, things will break. At some later point, we will work on a cleaner that will remove these extra files. Until then, enjoy! (Don't worry, upgrading to 3.03 OE firmwares still works fine).
