Anyway, You need to apt-hold bootloader package for blocking automatic bootloader upgrade.
If you can boot Orange Pi Plus / 2 successfully, type this on you shell;
sudo apt-mark hold linux-u-boot-orangepiplus-current
TIP) You can upgrade to latest armbian from 22.08.1 image directly.
Install 22.08.1 Image, type `sudo apt-mark hold linux-u-boot-orangepiplus-current`, and type `sudo apt update && sudo apt upgrade -y`.
