GigabeatTInfo

General Information

The Toshiba Gigabeat MET series of DAPs are largely based on the same hardware platform as the Gigabeat S and Gigabeat V series. However, it is a flash storage-based device, unlike its hard drive-based brethren. Rockbox has not been ported to this device yet, but a port is possible as it's mostly the Gigabeast with flash. The firmware is extremely similar to the S and V as well, but a digital signature exploit needs to be discovered so we can patch the beast bootloader to it.
