## How to use pmbootstrap

Switching devices:

    pmbootstrap config device <new_device>

e.g.

    pmbootstrap config device pine64-pinephone
    pmbootstrap config device samsung-herolte
    pmbootstrap config device qemu-amd64

Building for Samsung Galaxy S7 (samsung-herolte):

    pmbootstrap install --android-recovery-zip

Building for Pinephone (pine64-pinephone):

    pmbootstrap install --sdcard BLOCKDEV

Building for qemu-amd64:

    pmbootstrap install
    pmbootstrap qemu

## How to install on Samsung Galaxy S7

(See https://wiki.postmarketos.org/wiki/Installation_from_recovery_mode )

Reboot holding power + home + volup to enter the recovery. Choose
Advanced, ADB sideload.

Then run

    pmbootstrap flasher --method adb sideload

## How to use RNDIS to connect via ssh over USB

(See https://wiki.postmarketos.org/wiki/USB_Network )

For pinephone, which *does* get a MAC address for the RNDIS device:

    sudo ip a del 10.42.0.1/32 dev usb0
    sudo ip a add 172.16.42.2/32 dev usb0
    sudo ip r add 172.16.0.0/16 dev usb0
    SSH_AUTH_SOCK= ssh user@172.16.42.1

... or, huh, just use DHCP to get an address from the phone! It turns
out to work.

The equivalent for samsung-herolte is similar but requires inventing a
MAC address and assigning it at the link layer:

    sudo ip link set dev eth0 address 12:12:12:12:12:12
    sudo ip a add 172.16.42.2/32 dev eth0
    sudo ip r add 172.16.0.0/16 dev eth0
    SSH_AUTH_SOCK= ssh user@172.16.42.1

## How to set up WiFi on a running instance

(See https://wiki.postmarketos.org/wiki/WiFi)

When you pick "none" UI, you get no nmcli *or* wpa_supplicant.

Pick "console". Then you get both.

    sudo nmcli device wifi connect <SSID> password <PASSWORD> ifname wlan0
