Asus S510UA - Where can I get a new BIOS?

BIOS/UEFI Modding BIOS Modding Requests
1

I need a clean BIOS for the Asus S510UA.
Core I5 ​​7200U
UHD 620
Backlight keyboard

My original motherboard was defective and I replaced it with another one, but the keyboard backlight does not work. Possible to be disabled in the BIOS, the hardware is ok.

Sorry for the English, I’m using a translator.

@andreleao - Do you still have old board? And, do you have flash programmer or not?

Please dump BIOS region for me using info below, just do step #1 and send me file so I can check. Also, if you have ANY previous BIOS dump of the original board, before it was bad (or now with programmer), include this file as well

If you have already modified the BIOS in ANY way, you will need to re-flash it back to factory defaults using factory method (NOT FPT)!!!
Additionally, please remove all BIOS passwords, disable secure boot, and disable TPM or Encryption if you have enabled. Do this before moving on to below

If you do not have Intel ME drivers installed, install them now from your system driver download page, then start over here after reboot.
Check your BIOS’ main page and see if ME FW version is shown. If not then > DOWNLOAD HWINFO64 HERE <

Once HWINFO is open, look at the large window on the left side, expand motherboard, and find the ME area.
Inside that section is the ME Firmware version. Take note of the version. (ie. write it down or get a screenshot)

Once you have that, go to the thread linked below, and in the section “C.2” find and download the matching ME System Tools Package for your system.
(ie if ME FW version = 10.x get V10 package, if 9.0-9.1 get V9.1 package, if 9.5 or above get V9.5 package etc)
> DOWNLOAD " ME System Tools " packages HERE <

Once downloaded, inside you will find Flash Programming Tool folder, and then inside that a Windows or Win/Win32 folder (NOT x64).
Highlight that Win/Win32 folder, then hold shift and press right click. Choose “open command window here” (Not power shell! >> * See Registry file below *).

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

((If “open command window here” does not appear, look for the “Simple Registry Edit” below…))

Step #1
Now you should be at the command prompt.
You are going to BACKUP the factory un-modified firmware, so type the following command:
Command: " FPTw.exe -bios -d biosreg.bin "

>> Attach the saved "biosreg.bin ", placed into a compressed ZIP/RAR file, to your next post!!! <<

Step #2
Right after you do that, try to write back the BIOS Region dump and see if you get any error(s).
Command: " FPTw.exe -bios -f biosreg.bin "
^^ This step is important! Don’t forget! ^^

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

Here is a SIMPLE REGISTRY EDIT that adds “Open command window here as Administrator” to the right click menu, instead of Power Shell
Double-click downloaded file to install. Reboot after install may be required
> CLICK HERE TO DOWNLOAD CMD PROMPT REGISTRY ENTRY <

If the windows method above does NOT work for you…
Then you may have to copy all contents from the Flash Programming Tool \ DOS folder to the root of a Bootable USB disk and do the dump from DOS
( DOS command: " FPT.exe -bios -d biosreg.bin " )

Intel ME ver: 11.6.10.1196


Unfortunately I don’t have the old BIOS. I have the current BIOS working perfectly, but only the backlight does not work.
Yes, I have a CH341 recorder.

The card I bought came with the X510UA version, and from what I researched, these models do not have a keyboard backlight.

I’m thinking of testing this version to see if it works: [HELP] ASUS s510ua-db71 WINBOND W25Q64JVSIQ BIOS read and write

I am very grateful to be helping me

I tried to use this BIOS from the topic but it didn’t work.

@andreleao - You can’t use BIOS from any thread you see FPT being used it, it would replace your board info (serial, UUID, MAC etc) with other users info as explained in that thread
Which BIOS did you use from there, and how did it “Not work” << What do you mean, what happened, BIOS didn’t work or backlight didn’t work etc?

S510UA = X510UA - Same/Same, the X510UA is just Asus Internal Name, compare each one BIOS download page, and you see same BIOS for each (but each does have 4 variants)

Is the google link above programmer dump from your board? If yes, please wait, let me discuss something with another member

@Sylar76 - In regards to BT tool, I remembered you had a lot of experience, and I found out discussion here too. Do you know what to do when BIOS does not originally contain CNFG entry in NVRAM?
Can it be added with BT tool by direct use, or does that only work if CNFG already present in NVRAM? If the latter, I’ll have to rebuild his NVRAM or swap with donor for a bit
This users dump has it post #3 (But currently FF @ DD) - Asus S510ua bios startup password lock
This users dump has it also post #3 (7E @ DD on his, but unknown if 7E is correct for this model, we did not discuss then) - [HELP] ASUS s510ua-db71 WINBOND W25Q64JVSIQ BIOS read and write @cobrachaos - Does your KB backlight work?

@Lost_N_BIOS

Hi mate. I think he could try to use 7E with BT.exe or change NVRAM CNFG after extracting and replacing with UEFI Tool.

The only way to see if it works is trying.

6

@Sylar76 - Thanks for stopping by His BIOS does not contain CNFG NVRAM entry, that was my main thing I was asking you about, do you know if using BT automatically creates a CNFG entry?
Or, is your last comment my answer, you don’t know and we have to try and see? If you are not sure, then I’ll probably just use donor NVRAM and get it sorted out that way, I don’t want him to get bricked again due to BT trying to write to entry that isn’t there and mess something up and then him have to recover again.

I think BT.EXE is the better choice as that syntax is used for almost any ASUS Laptop. I don’t think it will brick anything.

Hi, did not turn on the notebook.

I think I’ll end up giving up on that. I am already afraid of damaging the PCB by welding and removing the CHIP several times.

The CH341 does not allow me to record the chip without removing it.



edit:
I was making the recordings in another CHIP that I have here so as not to damage the original.

Now I have returned the original BIOS in place, but the notebook does not turn on anymore. Does not turn on the charger led.

@Sylar76 - Yes, I agree, to fix issues, but I think I tried before on system without CNFG entry and it didn’t work, but I can’t remember for sure, that’s why I asked.

@andreleao - Probably bad write then, what is the BIOS chip ID, and what software version are you using? You need to get SOIC8 test clip with cable, so you don’t have to solder/desolder Let me know if you need linked example, it’s only around $3.50
If you have clip and can’t read chip, then try with main battery installed, then if no luck, try with PSU cable connected. Other users do not need to remove chip on this model to read/write, so you should be able to get it with clip

Sounds like you have bad solder if it’s not starting now with known good programmed chip. Make sure all solder is melted and good joint, no cold joints, and make sure it’s in correct position. I’d say check and make sure pads still in place, but you have to do that before you solder back on, after you clean pads and get ready to put chip in place.
Always use lots of flux, it really helps things flow properly

You really hit my friend, it was the bad solder. I redid it again and went back to working ok with the original chip!

I do have the clip for recording on the spot, but it didn’t work. I will test it as you said, with the battery on when I try to make a new recording, but I confess that now I’m afraid. Better it working without backlight than death once and for all …

11

@andreleao - Great to hear you got it working again, nice!!

Since you have programmer and clip, we can always fix, don’t let it scare you Yes, if battery connected does not let you get a good read, then also connect main power cable.
Sometimes with clip, you have to try it on there 10+ times before you get a good connection too, so you may have just had that issue before and battery or PSU may not be needed. I’ll tag some users with same system below and ask if they had batter or PSU connected when using clip
@CPR @cobrachaos @j0nA - When you guys connected to BIOS with clip, did you have to have battery or PSU connected to get a good detect or read/write, or was it OK with both removed etc? Thanks!

12

Definitely did not need to have battery or PSU connected to read, but took a number of tries to get a good connection.

13

@cobrachaos - Thanks for confirmation, so no battery or PSU needed, just the usual “plethora” of attempts to make clip be that perfect connection, I know all about that
Funny, sometimes it takes 10 attempts, and then other times one clip on and it’s perfect, while of course all attempts look and feel perfect

Now I gave up on messing with the BIOS and did what you just suggested, I turned on the backlight separately. With I will not have a manual control for the backlight (there is no way to put a button, or have to change the notebook’s housing for that), I made a luminance sensor with LDR, put it on the ventilation grille and it controls the backlight automatically, only lighting and controlling the brightness according to the ambient brightness. I also got a + 19v signal from the charger, so when it’s just on the battery, the backlight brightness gets even lower and only lights up when it’s really dark. I liked the result. An Attiny13a is reading the sensors and controls the PWM for the led.

I sincerely thank you for the help you gave me here on the forum.
