Warning

There are three separate FLASH ROMs in your device. Each can be independently upgraded. All can be interrupted in mid flash, or corrupted, rendering your device into an expensive ashtray.

Authorized ROM Upgrade

The only approved upgrade is the one for your phone. Do not apply a patch unless you know for a fact it's the right one for your phone. If your phone turns into a brick, there will be one person who is responsible for that, and that's you.
