Hi,

I am trying to downgraded my iphone from 1.1.1 to 1.0.2. I had tried to install FW Changer…which got almost through the install process and gave me the “main script execution failed!” error (which I still get when I try to install this app). I tried Tried to reinstall installer and get same error. any ideas?

Download putty on your computer or terminal on your mac, type commands one by one then reboot :

cd /
cd Applications/
wget download
rm -rf Installer.app
unzip Installer.zip
chmod +s Installer.app/Installer
chown -R root:wheel Installer.app
rm Installer.zip
