Welcome to Windows Central! I'm sorry to regretfully say this, but no Windows Phone 7.8 device is upgradeable past that point due to hardware limitations. Sorry. :/

re:

Zulfigar is correct. They changed the Kernel in WP 8.0 and Win7Phone hardware can not upgrade.

Sell the Lumia 800 as a "rare antique" on ebay and buy a new phone.
