Upgrading firmware from Lite-On LTC48161H to SOHC-5232

I have a lite-on 48x24x48x16 and was wondering if i can upgrade the firmware to 52x32x52x16.

LTC48161H to SOHC-5232K

Thank you

No, you cannot.

even if you could there would be little difference 48x and 52x are just marketing rubbish to make you think its better in reality its 1 or 2 seconds faster, all you will do is compromise the reliabilty of the cd and probably wear out your drive faster than it should be.
