Please help with asus black screen (no logo, no bios)

USB not compatible then, or BIOS so corrupted it can't start recovery, only way you could know for sure is if you had already done this process in the past and had a known compatible USB Stick. You can try to borrow or find some small cheap USB Sticks, look at friends, in junk drawer, or old office junk storage etc, maybe you can find some cheap ones someone will let you have or borrow.

If not, order the above tools and wait 3-5 weeks usually, sometimes you can find in local shops but it usually costs more. EZP2010 or EZP2013 kits often find local too, or maybe ebay or amazon seller offer faster shipping for more $$ if you can't wait long time

Ok.
Many thanks.
Best regards.

Keep trying, hopefully you can find working USB, and use that .bin 2KB smaller file I sent you, I think maybe the USB used is the issue more than super-corrupted BIOS. Also, try on a spare HDD, or make a small FAT32 partition at the end of your main HDD, recovery should see that first, but if not try to find more USB to try,

[junjo]

I tried with the hdd and not changes (512Mb FAT32 partition).

The hard drive led blinks short once and nothing more.

But I keep trying

[junjo]

Do you know how long the process takes?

Edit:
I found this:

Edit 2:

I tried with 1gb flash drive (FAT32) and with your file renamed to X550JK.bin
The led indicator blink (slow blink) non-stop for long time (more than 35 minutes) but without changes.

Usually it blinks for 1-2 minutes, getting faster as it nears the end, then it stops (May turn LED off, or stay solid)

35 minutes it too long, it's either done or failed. Did you stop and reboot yet? Can you connect an external monitor to this system? If yes, try also having that connected when you restart, in case graphics card is bad then onboard GFX from CPU would be used, or if LED panel is bad, then external monitor may show image instead.

OK. I think it's a USB flash drive failure. Tomorrow I will try two USB flash drives(1Gb and 2Gb).

Did you stop and reboot yet?

Yes.

I have connected an external monitor in all my tests. (VGA and HDMI)

[junjo]

New test preformed with 1Gb and 2Gb USB flash drives.

The USB flash drive led blinks 5 seconds approximately.
The screen backlight is on for 5 seconds approximately.
Power led and num. lock led is on for  5 seconds approximately.

After 5-7 seconds only the power led is on

I have waited 10-15 minutes and without changes.

Any other smaller flash drives to test? It could simply be too corrupted to recover, I'd go ahead and order a programmer and test clip cable, may be the only way you can fix this.

For  the moment I do not have but I'm looking.

I waiting this pack:


SOIC8 SOP8 Test Clip
CH341A 24 25  Programmer
1.8V adapter CH341A


PD:
Do you know if this programmer is valid for the phoenix BIOS?
