Bios menu unlocked for ASUS TUF Gaming FX505DU




Following is  some screenshots of modify before and after menu unlocked for ASUS TUF Gaming FX505DU.

Below is original tabs before modify.



After re-flash modified bios , we can see several new tabs appear in bios interface, it contains most useful features on new Advanced tab .



There is no better way to re-flash mod bios on amd platform of ASUS laptop series , so SPI programer is the only method to backup and re-writed bios.
On this sample , user Tomonok also writed bios with an programer(ch341).

I can help out modify with the same model of laptop if anyone can provides the dump bios by SPI programer.

I recently have  new ideas to let AMD CBS menu appear in bios screen , a thought into my mind few days ago.
But i don't have this machine to do any tests ,i'm hope that if someone has the same laptop and also have SPI programmer ,please backup local bios and send to me to do modify testing


New progress updated at 20201107
================

I seem successfully unlocked AMD CBS menu , please visit some capture screens below.






 

These feedback still from user Tomonok , He help me out to verify my modifications at his machine ,then finally got the my goal ,but i thought this mod not perfect yet ,i still need to fix it steadily.

He also overclocking his memory to ddr4 3000 ,and it seems running stably.

    1. Do you have an hardware spi programmer?
      It need programmer to read/write bios chip in the laptop of AMD platform.

  2. I have fx505dt and bought the spi flasher a while ago :) i have kingston hyperx 2666 with excellent timings (may even overclock) but the stupid bios! Mine is the same as the DU version just 3750H and gtx1650.
    I dont have a spare bios chip though i will find one and order online.
    Good with basic soldering and have solder paste so maybe can resolder new chip with heatgun 180 C instead of hard soldering one by one?

    1. Sorry ,no such files can let you download. If you want to request a mod for fx505du ,you have to purchase an hardware programmer then read/write data from bios chip. This device is necessary for bios modification in a AMD platform.
