After updating the keyboard in myAsus app, the keyboard and backlight stopped working completely, including BIOS.
I decided to share the solution, because asus support cannot offer anything, except carry the laptop to service and leave it in service center.
After 2 days of suffering, I found a solution.
After resetting win10, myasus prompted me to re-download the keyboard update, but the update was failing.
I found a folder with a log file and my problem was:
Tool Version : 2.2.4
Product Name : GX701GV
[Initialize] Start Flash : 20210103203630
[Initialize] GetKBType : 0
[Initialize] UnReg LightingService
[Initialize] Battery Power Level : 100
[Initialize] GetASUSDevice fail
[Initialize] GetITEDevice
After that I decided to find the original installation file for the firmware, which is located in the C/ProgramData/Asus/ASUS System Control Interface/AsusSoftwareManager/2 folder and is deleted immediately after an error in myasus.
In the original file, I found the keyboard firmware files. Then I solved the problem that stopping flashing process with error "[Initialize] GetASUSDevice fail".
Solution was very simple, I downloaded KBFWUpdateTool_v1.0.5 and and moved the update file F0NK1100.GX701GV.308.bin to KBFWUpdateTool_v1.0.5/fw folder.
Then just run ROGKBFWUpdateTool.

P.S. I like ROG notebooks, but i hate asus support and asus software updaters!
