Swapping firmware between SMP and 2014 WDTV?

I have the newer WDTV. Because the hardware is supposedly identical between the SMP and WDTV, what is keeping me from installing firmware from the SMP on my WDTV? Since the latest update to the SMP, it seems that it now has all the features of the newer WDTV (miracast, usb apps, ect.).

Potentially bricking your device and voiding your warranty ?

Just to note: the file sizes of the firmwares are not indentical

wdtvlivegen3_2.02.32.zip    (Zipped: 174.59MB  Unzipped: 177MB)

wdtv_1.01.30.zip                    (Zipped: 160.71MB  Unzipped:164MB)

You cannot install firmware for one model onto another. There are internal mechanisms that prevent this.
