After the reading/dumping process, you will need to take the clean 1.02 (or any other UHD Friendly firmware) and prepare it with data imported from the original dump.If everything looks fine, select first "Read Flash", in order to dump the current firmware.If not you have not properly set the SATA controller or it is not compatible with DOSFLASH. Now, you should see the BH16NSxx (or ASUS) device listed.Wait few seconds to allow Windows 7 properly loaded and as soon as the Windows 7 desktop appears, go to "My Computer", open the USB device letter, and run DOSFLASH32_BH16NS40.exe.Enable CMS in BIOS option in order to boot from the USB stick (NOT UEFI !!!!) and configure SATA controller as IDE !!.Unzip on USB stick root the DOSFLASH_Windows7.zip attached file below.Use Rufus and select the ISO image previously downloaded and prepare the USB stick.Download the Windows 7 Live (Portable Edition) ISO from here.Steps for dumping firmware : (Windows Method)
DOSFLASH modified version (attached below).A motherboard having SATA controller set as IDE (not AHCI !!!).An USB stick DOS bootable (which can be made by Rufus tool).Here is my own guide to successfully dump and downgrade firmware on any "UHD Friendly" devices, such as Asus BC-12D2HT / BW-16D1HT or LG BH16NS40/NS55 (WH16NS40/NS55) (SVC Code NS50) and similar drives having MediaTek chipset inside them.
