$ git clone gitlab.com/pos...
$ cd pmbootstrap && python3 setup.py install
3. Flash bootloader github.com/msm... for Samsung A5 is lk2nd-msm8916.img
Put phone into fastboot mode: Volume Down + Power + Home
$ heimdall flash --BOOT lk2nd-msm8916.img
Once you see lk2nd fastboot screen with green START you can build software
Building software:
$ pmbootstrap init
Then:
$ pmbootstrap install
Prepare phone:
$ fastboot erase system
$ pmbootstrap flasher flash_rootfs --partition userdata
$ pmbootstrap shutdown
$ fastboot reboot
Install docker (after connecting to WiFi) and connect via SSH
$ ssh [username created during installation]@[IP address of samsung]
$ apk add docker
$ addgroup [username] docker
$ rc-update add docker boot
$ reboot (to make addgroup username docker alive)
& apk add docker-compose
& apk add py-pip python3-dev libffi-dev openssl-dev gcc libc-dev make
& pip3 install docker-compose

docker volume create portainer_data
docker run -d -p 8000:8000 -p 9000:9000 --name portainer \
--restart=always \
-v /var/run/docker.sock:/var/run/docker.sock \

This is so useful I can see if a can use it as use as possible

[@BetagameTest]

The only problem it is the gpio functions but good work man

[@Henry-sv3wv]

maybe an arduino on the usb OTG works as "GPIO"?!
but can you charge it with an active hub at the same time?!

[@Henry-sv3wv]

then you can't put external power on it like a raspberry pi
But i want a cheap linux phone like this to experiment with ...
