rule of thumb is I eyeball the firmware before I even download off the net.Ones that boot so far are the 2meg flash varieties or if 4meg the .zip or .rar will be around 1.6meg.Compressed files that are 2meg and slightly bigger don't boot.These are firmwares with m3602a or m3602b as part of the bootloader name.
The --- ones in the name are close enough to the original smt---1.0.0 to boot at least.
