How to install "permanently"

1. download orangefox image here.

2. dump your boot image with mtkclient:

python3 mtk r boot boot.img

3. flash orangefox image to your boot_a "or boot" partition

fastboot flash boot OrangeFox-R12.1-Unofficial-fire.img

4. reboot to recovery

fastboot reboot recovery

5. Once booted, put your stock boot image in Internalstorage , MicroSdcard or Usb-Otg then Flash stock boot image in boot partition and tick (Flash to both slots) (this will remove OF recovery form your device; you need to reflash orange fox from menu>Flash current OF). after that it is better to flash OF.zip file
