Jump Drive for the Pine Phone Pro

[LPIZ]

Hi,
I don't understand how works Tow-boot.
How I use Tow-boot ? Do I use it like jumpdrive ?
Can I install an os on my pinephone pro with etcher with Manjaro desktop on my computer ?

When you install tow-boot, you have 3 different options upon boot.

1) eMMC - turning on the phone and leaving it along will boot to the OS on the eMMC
2) SD card - when the red light turns on after booting it up, hold the volume down button until the phone buzzes and the LED finishes changing colours (I think it cycles from blue to white or something like that). Let go of the volume down button once the LED stops cycling
3) USB storage - when the red light turns on after booting it up, hold the volume up button for a few seconds and you can connect the PPP to a computer to access the eMMC. You can easily flash a new OS to the eMMC using this method. This is the method you can install a new on the PPP using etcher

There are some YouTube videos that guide you through the process as well, but this is it in a nutshell.
