Hi guys!

The keyboard is not working. The customer tried other keyboard, too.

I checked +5VS -> OK and also flashed IO firmware with Vertyanov. Still the keyboard does not work.

No shorts measured on KBD connector pins.

Please advise!

KBC, firmware. If there is a keyboard controller, then the matter may be in it or in its firmware

Hi there! Does this laptop have a power button on the keyboard? Perhaps the new keyboard is defective. Try another keyboard

Check the VCC on IT8171FN-56, SM and USB data lines, resistors and etc.

this motherboard has two controllers. Vertyanov targets the 128kb (IT8995VG) and read/write is successful. How can I use Vertyanov for IT8171FN-56?

some solution is here but still does not explain how to write IT8171FN-56.

j3101 only for 8171


for 8995 need use JDEBUG2


What plug (connector) and what did you program?

Did you try https://dlcdnets.asus.com/pub/ASUS/nb/G ... ER1030.zip
? It's kb adjustment tool for this model. If it wont work, extract FW_NK0003000B with 7zip and flash thru vertianov.
pins:
KB_pins=30 LEFT DOWN FLASH=56 PD0=29 PD1=20 PD2=15 PD3=23 PD4=14 PD5=16 PD6=12 PD7=30 BUSY=26 STB=18 AFD=28 INIT=21 SLIN=19 KSI4=22 KSI5=24

thank you both for your replies. I am obliged.

so far I flashed 128kb file through keyboard connector J3101 which is wrong yes?? I must flash 56K file using the J3101 keyboard connector?

Today I will try the program first and then check again with Vertyanov.

I also do not know how to use jdebug2 connector for 8995... much of a noob me.

Yep. Flash it to 8171 through J3101.

You no need to flash 8995 yet.

I tried the software but says no compatible device found "Searching USB device, Not found, Retry"

I will now use Vertyanov but:

the FW_NK0003000B firmware is 56kb and the file you attached is 2.5MB... what should I flash through J3101?

ok I found a problem!

I flash the 56K file FW_NK0003000B to IT8171 but the EC rom does not write the data. When I read back its empty! And of course Vertyanov says "Data is not the same" when verifying.

BUT the IT8171 is detected properly by Vertyanov. Is IT8171 damaged??

I use this setting:

GL502VM KB_pins=30 LEFT DOWN FLASH=56 PD0=29 PD1=20 PD2=15 PD3=23 PD4=14 PD5=16 PD6=12 PD7=30 BUSY=26 STB=18 AFD=28 INIT=21 SLIN=19 KSI4=22 KSI5=24

I am sorry to be persistent I need the guru help regarding this issue... the chip is DETECTED and PROGRAMMED by Vertyanov but it stays EMPTY?

any experience how is this possible? dead IT8171? some other issue?

please share your ideas.
