Tried both suggestions above using cable plugged into a charger and it still won't boot to the recovery menu.
EDIT TO ADD WORKED WHEN PLUGED INTO LAPTOP BUT WOULDN'T WORK PLUGGED INTO CHARGING BLOCK. WHAT A PAIN IN THE BUTT
Can't get my Tab S11 to boot into the recovery menu by holding down the power button and volume up button simultaneously.
What's missing or has the process changed?
