I purchased the LG drive model GSA-4120B which originally came with firmware "A102". I flashed with the latest official firmware "A111" and not sure if the problem is related to the new firmware or not, I just noticed that the drive no longer read the DVD-RAM discs that I recorded with the firmware "A102", it is showing as a blank disc asking if I want to format.
When I called LG technical support, I was informed that I should never "Jump Up" when flashing firmware, the recommendation is to always "Step Up", in another words start with original "A102" than go to "A104", next "A110" and last "A111". Also technical support told me that I can't flash back to the original firmware.
Please let me know what is the correct way to flash firmware, not sure if are different recommendations depending who is the manufacture or if this is a standard procedure.
I appreciate your comments.
