Attention! If the device was introduced to a google account after the reset to factory settings via recovery menu, your phone will require her to enter for activation.
To reset on a Samsung Galaxy S10+ you need to enter recovery and perform a wipe. This is done by the following algorithm:
Turn off the phone. If it's locked and will not turn off, press and hold the button "Volume -" and "Power" for 7-8 seconds.
Then simultaneously hold down the "Power" button, "Volume +" and "Bixby"
After 5 seconds release the button "power". Buttons "Volume +" and "Bixby" hold until recovery menu (5-10 seconds)
Buttons "Volume +" and "Volume -" to select "wipe data/factory reset" and confirm your selection by "Power" button
Then select "Yes" and confirm your selection by "Power" button
If the phone is frozen and unresponsive, try to perform Soft reset. To do this, hold the button "Volume -" and "Power" for about 10 seconds. The phone will reboot. All data will be stored.
