I'm new to this forum (been lurking for a few days), but I've done as much research as I can into the subject, now I'm reaching out to you guys.
My TV, the PN50C490, runs the T-VAL4AUSC firmware, which appears to have limited support (via Hotel Mode menu) for Wireless/DLNA, but I can't seem to get work fully. Switching the model to various other C series Plasmas (like the C7000 or C8000) enables the network configuration interface and Allshare, but appears to disable use of the USB port (very odd), making use of a USB wifi adapter impossible. In my further research, I noticed that the firmware would seem to imply (both in it's file structure and naming convention) that unlike other low-end 2010 Plasmas, the C490 runs an ARM processor, not MIPS. This would also be in line with it being the only low-end 3D set. This leads me to wonder:
Would it be possible, with some limited modification of the update files, to flash the firmware from T-VAL4AUSC to T-VALAUSC, in doing so installing Internet@TV, full wireless and DLNA support, and other such goodies?
I understand that this may be a stupid question, but it's the simple similarities between the two firmwares (comparing them side by side from my computer), that seems to imply that cross compatibility may be possible. It's also my understanding that if my tv WERE mips based instead of arm, the firmware would not be named T-VALXXXX but instead T-MSX5XXXX. Is this correct?
Thank you for your help, don't hesitate to criticize or ask for more information.
