Help! DVD+R DL support on Philips dvdr824 dp



Hi. I’m new to these forums and I need some help… I have an hp 400i (really a 400c) dvd burner that i have flashed to the philips dvdr824dp p 3.4 firmware through reading other threads on the forum. I started the whole process to get my drive to recognize DVD+R DL discs. My question is where can I go from here to get this drive to read Double Layer DVD+R discs(only reason for doing this)?
Any help would be much appreciated.
:bow: :bow: :bow:


I have also tried to follow the leads about cross-flashing to a BenQ drive, but I have not had success so far, I need some more specific help.
