Downgrading the firmware for LiteOn iHAS324 E

My LiteOn iHAS324 E (4L17) doesn’t burn the Ritek DVD disc well.
I want to test it with older firmware (4L14) but the utility doesn’t let me.
Is there anyway to downgrade?


I think it is possible to downgrade, but you need to have the binary of the firmware you want to flash.

However, I doubt it will help and you should probably try better media.

Links are dead there.
I tried other LiteOn drives and they worked fine with Ritek.

Did you try using the Smart Burn utility to clear learned media?

Isn’t Smart Burn utility for detecting the write speed?
I always use 8x

It has several functions, including clearing the “history” of the media it has burned so far. This is useful because if among good discs you have a bad batch clearing the learned media “resets” the drive to the default write strategy.

I get this error:


I get the same error with iHAS124 E, so it seems that SMART-BURN is not working with these drives.
