I was OC my 48246S to 52246S and works fine.
First go to http://liteon.notrix.net/ and download litefirm2.exe to convert LiteOn exe firmware file into binary file.
Download mtkflash155.exe at same page.
Download latest firmware exe file from liteOn page for 52246S
Convert downloaded exe firmware file into bin file (in my case 6s0c.exe into 6s0c.bin) with litefirm2.exe.
Upgrade your 48246S with converted bin file using mtkflash155.exe. Reboot your system and that´s all.
Very easy, great results.
… And remember, SAY NOT TO THE WAR…
