LB BH10LS30 can't burn BR's anymore

Wonder if anyone can help me out with my Problem. I used to made an Firmware update, since my LB BH10LS30 drive was unable to read 50GB Verbatim blanks. Now it does not work anymore. It burns CDs and DVDs perfectly, Plays everything, but it is not working with BRs or DL-BRs anymore. I used to work with Verbatim blanks only, since the last couple of years, and never had Problems. I already tried to reupdate it to the old Firmware Version, no success so far. I also formated my PC and resetuped everything again, no success aswell. This is the error message I got, when using ImgBurn. Also not working on other burn sofware programs :-(
