Installation from recovery mode
Most Android devices have a "recovery" partition, on which a second kernel and initramfs can be installed. The recovery systems installed there allow overwriting the main OS with a special zip file, and it is possible to generate such a file for postmarketOS.
Create the recovery zip image
$ pmbootstrap init $ pmbootstrap install --android-recovery-zip
By default, this will install to the
system partition of your Android device. If you want to install to a different partition (e.g. because your
system partition is too small), use the
$ pmbootstrap install --android-recovery-zip --recovery-install-partition data
This allows downloading the zip file on the fly directly from your computer. If you don't want to sideload, you can also copy the generated zip file to an SD card.
- Boot the recovery system
- Click on "Advanced / ADB Sideload", then "Swipe to start sideload"
- Connect your phone to your PC
- Start the sideloading process from your PC:
$ pmbootstrap flasher --method=adb sideload
Sideload without pmbootstrap
If sideloading with pmbootstrap fails (it was broken in #1638), you can do it without pmbootstrap as a workaround. Install
adb on your host Linux distribution (usually in an
android-tools package that you can install with your distribution's package manager), then run the following commands. The special
cd is necessary, because
adb can't resolve the symlink on its own.
$ pmbootstrap export [07:48:04] NOTE: To export the rootfs image, run 'pmbootstrap install' first (without the 'sdcard' parameter). [07:48:07] Export symlinks to: /tmp/postmarketOS-export [07:48:07] * initramfs-lg-mako (Initramfs) [07:48:07] * boot.img-lg-mako (Fastboot compatible boot.img file, contains initramfs and kernel) [07:48:07] * vmlinuz-lg-mako (Linux kernel) [07:48:07] * pmos-lg-mako.zip (Android recovery flashable zip) [07:48:07] NOTE: chroot is still active (use 'pmbootstrap shutdown' as necessary) [07:48:07] Done $ cd $(dirname $(readlink /tmp/postmarketOS-export/pmos-*.zip)) $ adb sideload pmos-lg-mako.zip loading: 'pmos-lg-mako.zip'... connecting... Total xfer: 1.08x
Copy the generated image to an SD card
Instead of sideloading, you can run
pmbootstrap export and copy the
pmos-*.zip file to an SD card. Insert it into your phone, boot into the recovery system, and select "Install". Then navigate to the zip file, and the postmarketOS installation should begin.
TWRP reports that no OS has been installed. This happens, because it can not detect postmarketOS installations (#1451). Just ignore it and reboot into your fresh postmarketOS installation.
