==== Tow-Boot ====
This is required for the following operating systems. Tow-Boot is already installed by default on newer PPPs.
Download the latest release for your PPP - https://github.com/Tow-Boot/Tow-Boot/releases.
Extract it and flash ''spi.installer.img'' onto a SD card:
Insert the SD card into your PPP and __**press**__ and //__hold__// the //__volume down__// button. Now //__press__// the //__power button__// until the __//first vibration occurs//__, then release the //__power button__// but continue to //__hold__// the //__volume down__// until the __second vibration occurs__.\\
You should now see a //__blue LED__// and the Tow-Boot start screen should appear.\\
''Install Tow-Boot to SPI Flash''.
When everything is done, switch off your device and remove the SD card.
Switch to //USB mass storage// - __//press//__ and //__hold__// the //__volume up__// button and //__press__// the //__power button__// once. You should now see a //__blue LED__//. Connect the device to your PC via USB.
Create your own Arch repository to keep older packages in case you need to downgrade your system/phone. It can be more difficult to downgrade than with the x86_64 architecture.\\
Simply follow the questions. Some necessary steps are listed below to use your PPP, the rest is up to you.
