Now that you have a firmware dump, you can flash it in the same model of DVD writer. I almost pressed Ctrl+C to close the program when it suddenly showed the message that process was finished. The process may take more than 10-15 minutes to finish. This will read the data from the DVD writer’s chip memory and dump into a file main_firmware.bin. Then give the command flasher -d 1 -m main_firmware.bin assuming your DVD writer has device ID 1. If you have only one optical drive, then this is completely unnecessary as your device ID would be 1. This will show you a list of all optical drives in your PC – not down the device ID for your target optical drive. You have to open an elevated command prompt and then give the command flasher -D. It is a command line tool, so you should know a little about running command line interface programs. This tool works only for some LG DVD writers. In order to dump the firmware of a LG DVD writer, you need a tool called Devilsclaw Flasher. The process worked – and now my DVD writer is working like it used to. So I had to dump (extract) the firmware from a friend’s working DVD writer of the same model and then reflash it in my DVD writer. LG’s website is no help – they do not provide any firmware for the model GH22NP1. But this time when my old faithful LG DVD writer started to show signs to senile decay, I decided to give it one last go and reflash its firmware to see if it makes any changes. I must have bought more than ten different CD/DVD writers in my life just to replace the faulty ones. Since DVD writers are no longer used as much as they were used 5 to 10 years ago, they get rusty and stop working after a year or so.
