Flashed to duallayer , can't burn single disc

i have flashed my Liteon451S to 832 , but now i can’t burn a singlelayer disc
Nero and all other burnprograms ask for a dualllayer-disc

what firware did you flash to?

Most apps will default to asking for a DVD of the max supported size , ie dual layer, but will give you the option to select either dvd9 or dvd5. That’s what Nero does for sure. I think that once you’ve selected DVD5 then Nero will default to that size , except maybe if the filesize exceeds DVD5. I’ve got a Liteon 851 converted to the 832 & that’s what happened for me.
