How to enter the Galaxy S10 recovery mode without a computer (One UI 4.0 or higher)

It didn't work as Samsung Pass suddenly showed that it had been rooting. And also some of menus have slowed down due to the recent update to Android 12. So I tried to enter recovery mode to initialize the factory today. 

No matter how much I pressed the top of the volume, Bixby, and power buttons, it just booted.

So I looked it up, and in One UI 4.0, when entering the recovery mode, it only enters when connected to the PC.

(I don't know if One UI 3.0 is also applicable.)

I wondered if I could use Type C gender, but I can't use gender and only in situations where I have a PC connection. 

And as expected, Samsung Pass is working well after resetting the factory.

Even if you initialize and put all your Samsung account in, Watch 4 is also initialized.

But if you don't have a computer, how can you solve it? There are three ways below. 

1. It is more comfortable to type "adb reboot download" than to press a button.

2. If you don't have a PC, you can enter the recovery mode even if you connect a Samsung smartphone with another smartphone through a cable.

3. You can connect it with USB DAC.
