Efficient will do nothing. In fact, they don't even acknowledge that this upgrade is possible. So don't bother emailing them about it!

Efficient is refusing to support anyone who is hacking their firmware. While the hardware in a "crippled" 5260 and is identical to the 5660, you can still mess up your firmware and/or modem. You are doing this at your own risk. I will claim that it is virtually guaranteed to work, but as with all flash BIOS if the power goes out or you pull the plug during a flash you are likely to render your modem unusable. SO DON'T TURN IT OFF OR UNPLUG IT WHEN YOU ARE FLASHING IT!!!
