i need build bios asus Q409z gen 12

[boomienutcake]

I have and Asus Q409ZA that I purchased new, and all was well until it eventually turned on to a black screen.

I backed up my original BIOS. I then downloaded and flashed an engineering BIOS posted by another member. It works great until something updates and the laptop starts up to a black screen, no activity. It can be reflashed with the engineering BIOS and work again until etc. etc.

I've attached the original dump of this laptop with its serial number and other information in tact. I've also included the new engineering BIOS. Maybe somebody could take a look and find out what the problem is, or rebuild my original.

Laptop : Asus Q409ZA (UX3402ZA)
S/N: N2N0LP00C329067
Motherboard : NB5936 V3.0


Thanks!

Merged post...

I managed to repair my original BIOS (so far) using the ME guide and doing a LOT of digging for v16 tools.

Major breakthrough, feels great to finally be back to using the original BIOS on this laptop. Hopefully it will last.

my sn is: N3N0LP02A42912G

I thought I might as well look at this one while I'm at it, maybe this will work too if you still need it cyllell. I know it's been over half a year.

Interestingly, the ME version v16.0.15.1662 is identical to my failed laptop BIOS.

I just want to thank Lisa Su for posting this BIOS. Absolutely saved my laptop from a no audio/boot hang issue.

I'm still under warranty with two weeks left, but don't want to deal with shipping/diag fee/etc. just to get a replacement laptop from ASUS.

My cheapy 3v3 modified CH341A (black) programmer worked out great. NeoProgrammer knows that it's connected, but doesn't recognize the IC (XM25QH256C). I was able to choose the IC's previous revision from the IC list (256B) and read/verify/write successfully.

Thank you thank you THANK you.

Hi, I have the same laptop and am currently facing the same issue. I have bought a ch341a from amazon, but I am very new to this stuff. I can't identify the bios chip. Could you help me identify if the bios chip is the one in the image below. Also, is it ok if I just flash the Engineering BIOS given or do I need to update anything on it. (I sent it for repair before trying myself but the repair guy ended up losing my original bios file without fixing the issue.)

I am also attaching another working BIOS file I found. Should flash that instead of the engineering BIOS? (Should I just replace all the SN on this BIOS and flash it?)

Thanks for the help.

Find the chip with the number 256 on it. For example: 25Q256xxxx

bios chipset is on the other side of motherboard

The Bios chipset is on the other side of the motherboard

Thank you so much. I found the chip on the other side (as shown in the image below). Please correct me if I'm wrong.

I tried a SOIC8 clip that came with my programmer, but it didn't connect properly. Would I need to desolder it using a hot air station? (Or would a standard soldering iron be enough?).

yes, that's the bios chipset. you have to desolder it

[boomienutcake]

I just ran some wires directly to the test pads around the IC, much safer and less work than taking hot air to the board.

yep, wires and CH341A = perfect combination for a disaster

The procedure is to load the file on a pendrive, place it on the PC with the damaged bios and start?

do you have a 1mb bin files for asus zenbook ux3042z

hi can you cleared my bios?
thank you for help

update contains only bios_region, not all bios. You have to upload your bios backup and somebody will help you to rebuild it.

Cyllell, I fixed you BIOS a couple months ago. Please see above, attached in post #23

i know but your bios is didnt work for me, can you clear this bios again?

[boomienutcake]

There is nothing more I can do from the file in the ZIP in post #23.

I hate to ask the simple questions, but what symptom does your laptop show?

If it is turning on with a black screen, are you waiting for the BIOS to initialize? The laptop will reboot two or three times before actually showing an ASUS logo. The initialization process takes around 2 minutes usually.

Hi, is there maybe a clip available to purchase from Amazon / ebay / Ali Express to avoid the need of desoldering the chip?

when i check your bios with me analyzer, i got this message. is it normal ?
