Bios Mods -The Best BIOS Update and Modification Source

Scenario:


Laptop ASUS x550JK (i5, Intel HD 4600 + Nvidia 850M)  upgraded to SSD and second HDD added (with CD/DVD to SATA adapter)

The motherboard model is X550JD Rev. 2.0

Windows 10 installed and tested OK.

Bios changes: Boot devices order

Save changes and exit.

After reboot the screen is black, no ASUS logo , no bios access.


Recovery test:

Latest bios  version downloaded from here: https://dlcdnets.asus.com/pub/ASUS/nb/X5...KAS303.zip

File renamed from X550JKAS.303 to X550JK.bin

File X550JK.bin pasted to USB flash drive formatted to FAT

VGA/HDMI cable connected to external monitor.

I have pressed the power button and CTRL+HOME keys. (USB flash drive connected to USB 2.0 port)

The USB flash drive led blinked 5 seconds approximately but without changes on the screen.



Any suggestion?

Many thanks.

Try reformat with windows simple right click format, to FAT32
Then put BIOS original file there and the renamed one, and a third one named X550JK.rom - all in root of USB

Smaller USB is better, you may need to try several small cheap ones until you find one that works good.

Remove both hard drives for now until you get this sorted out, and test both on another system to be sure OK. I say remove for now, in case one is shorting or causing this issue, or source of initially causing this issue, since you said OK until you changed boot order (invoking a different drive than what was previously running OK without this issue happening)

Thanks for your reply Lost_N_Bios,

I tested your suggestion but without any changes.

The USB flash led blink for 5 seconds and nothing more

Acording with this theard, the archive name is X550JK.bin

Yes, I saw that name in the BIOS itself too. Did you reformat the drive using simple windows right click to FAT32? You may need to try other USB, some are not compatible, often it's hard to find one that is compatible sometimes.

If you end up not being able to get it, you'll have to order a hardware programmer, like CH341A flash programmer ($2.50 on ebay), and SOIC8 test clip cable ($3.50 on ebay) or a kit like EZP2010 or EZP2013

Hi and thanks again.

My test:

Flash drive 4GB formatted to FAT and FAT2 and x550jk.bin file -- nothing

Flash drive 4GB formatted to FAT and FAT2 but wit 512Mb partition created on the flash drive and x550jk.bin file -- nothing

Flash drive 8GB formatted to FAT and FAT2 and x550jk.bin file -- nothing

Flash drive 8GB formatted to FAT and FAT2 but wit 512Mb partition created on the flash drive and x550jk.bin file -- nothing

SD card 256MB and 512MB FAT/FAT32 with USB card reader and x550jk.bin file -- nothing
(similar to this)
 

PD.
This is for different hardware but see the point 2. from Note:

https://www.asus.com/support/FAQ/114133/


2. If the light flashes for five seconds and turns into a stable lighting, this means that the BIOS Flashback is not operating properly. This may be caused by: (1) improper installation of the portable disk, or (2) error in file name or incompatible disk format. If this is the case, please restart the system to turn off the light.

Needs to be USB, or sometimes you can also create FAT32 partition on main HDD. For best results with USB on Asus, I've found 256MB-2GB best, smaller and cheaper/older = better.

No FAT or FAT2 (unless you meant FAT32?) Are you formatting with windows right click? If not, then please try that, but it's possible your 4 and 8GB drives are too large/new. Sometimes new/large is OK, all depends on the system, how new it is, what they put in the BIOS for compatibility etc.

It could be corrupted too badly to recover even with known working USB that you used on this system for this process before (If you had done it before I mean, as example), it can be that badly messed up. I don't think it is though, since you said it read one of your USB for a few seconds, that's usually incompatible drive or wrong format/file name/type.

You have put all these on there already correct? If yes, please leave or copy all these on there for each/any test you do, that way you are not missing any chances with wrong file name/type
X550JKAS.303
X550JK.bin
X550JK.rom
Also >> X550JK.CAP (Since this is a capsuled file)

And now, speaking of capsuled file above! Here is the non-encapsulated file. Try with that too, in place of X550JK.bin. Since renaming stock file to X550JK.bin is incorrect, that is still a capsule (.cap) file, the BIOS below is not, see the 2kb file difference. This may solve it all, use the USB stick where you saw the LED's flash previously for 5 seconds!

Also test with this file ^^ copied, and extension changed to .rom, since this is now actual .bin/.rom file.

Test with FAT and FAT32 (separately) with right click

OK no problem, but in this case the chip de-soldering process is required. It is true?
New chip is required?

For the moment I don't have a small usb flash drive

Yes.

YES.
OK.

OK. Thanks.

No, with CH341A you use SOIC8 test clip cable, or other kits I mentioned come with cable too. NO soldering or desoldering required
Here at ebay is example of SOIC8 test clip cable I mean

Hopefully the actual .bin BIOS I put above will work for you as it is, and or renamed to .rom too.

With this file the  led blink 2 (times)  x 5-6 seconds. File renamed to .rom, .bin, etc...
