sudo docker image rmi -f $image
# install the original image
sudo docker load -i redroidBak.tar

2.using moby method


  preserve original redroid image
wget -q "https://raw.githubusercontent.com/moby/moby/master/contrib/download-frozen-image-v2.sh" -P ~ ; chmod u+x ~/download-frozen-image-v2.sh

~/download-frozen-image-v2.sh "$image_tar" redroid/redroid:11.0.0-amd64


  backup or install original redroid image
# remove the changed image if exist
sudo docker image rmi -f $image
# install the original image
tar -cC "$image_tar" . | sudo docker load

setting up

mkdir ~/MagiskOnRedroid
cd ~/MagiskOnRedroid

to get magisk working do this:


phase

boot with magisk support

(
sudo docker stop a11
clear
sudo docker run -itd --rm --privileged \
  --name a11 \
  -v ~/data:/data \
  -v ~/remove.rc:/vendor/etc/init/remove.rc \
  -v ~/setup.sh:/setup.sh \
  -v ~/magisk.tar:/magisk.tar \
