Thanks very much to klutsh from MoDaCo for his amazing goldcard tool that removes around 10 steps from this process! See this post for more info.
Goldcarding basically tricks the phone software into thinking it's a generic device so that you can downgrade.
Windows only currently. Will erase ALL Data on SD Card so BACKUP!
Downloads
- Format your SD card to FAT32 by going Settings > SD Card & Phone Storage > Unmount SD Card then Format SD Card
- Launch the goldcard tool as admin by Right click on App > Run as Admin
- Connect your phone to your PC and make sure USB debugging is enabled (Settings > Applications > Development > USB Debugging)
- Click get CID (Try clicking MMC0 if MMC1 fails)
- Click the link to open the goldcard generator, copy the CID from the tool into it. You will get an email.
- Enable USB Mass Storage on your phone.
- Click 'Refresh' in the app and select your micro SD card.
- Click 'Load goldcard.img' and select the file you received by email.
- Click 'Patch MMC'
- You now have a goldcard!
- Now you can downgrade using the Generic RUU.
