Hyundai Grandeur 2016 Gen4 Engineering Mode

[Nightdriver]

Hello, colleagues!

I have a 2016 Hyundai Azera (Granduer), 4th generation (standard class, 4th generation, navigation)
SW ST.HG.USAE538

My question is: how do I enter engineering mode and change the region and language?

What is the password for engineering mode?
Please excuse my Russian, but I decided to use it as a matter of respect.

Thank you very much!

Hello. I have almost the same issue although My Grandeur (Azera) has custom head unit (TS10) so its probably impossible to change the region and language on the dashboard because it's all on korean language.
I heard you need to press the space left from the "Update" button 11 times and after that click once on the right side of the "Upgrade" , then a pop-up screen will appear and will ask you for a password. Something like that.
