It is recommended to use CD -R disc to create the firmware update disc. I hope you're clear with downloading the update from support page. Once you download and save the file in the folder in the computer, you can double click the file to extract. You will be prompted to save the UPDATE_BDPS300_VER0550.ISO file in a folder. Most of the customers will be making mistake here after... We need to use a burning software which is capable to burning discs from ISO images. ISO image is nothing but a RAW format of burned image. I will give you the instructions to burn using Nero.. Steps will be almost same in all ISO capable software. Open installed nero software from computer. You may locate it under Start Menu programs. Go to File Menu (Some times you will get a wizard where you can select the Image Burning option or burn ISO option) Navigate the extracted .ISO file we saved in the computer. follow the onscreen instructions. Insert the disc when ever Nero asked to insert Hope this helps. If you need any assistance. Please get back to me. I will be more than happy to assist you. Thanks for understanding.
