R U running from eMMC -- If so how?

[lllsondowlll]

Step 1. Install Tow-boot from sdcard
Step 2. Hold volume up while powering on to mount the eMMC over usb (Basically jumpdrive for Pinephone Pro)
Step 3. Install Manjaro by writing the image to the eMMC via mounted storage from my computer.
Step 4. I use my unofficial battery case to make the Pinephone Pro last all day with suspend disabled. I can make and receive calls, SMS, and MMS, all are all working. Daily drivable.

thanks, will give this a try.  You're first one to confirm mms working.  That's a big step forward for me.

R u using phosh desktop?  I am finding that better performing than plasma at present.

ok, I give up and will ask how to compile towboot to get an img file to install on SD.

Firstly, here are two towboots on github.  I want to confirm that you have sucessfully used the one called Tow-Boot by samueldf: not towboot by YtvwID.
What needs to be done to compile this?  openSUSE does not have any compiler called nix that is what appears to be needed.  Need a step-by-step instruction set to get towboot to a point where it can be installed on an sd.

Precompiled SPI installer can be found here 
https://github.com/Tow-Boot/Tow-Boot/pull/67

Download the WIP4 image for PInephone Pro, extract it, flash the SPI installer image to your SD card, hold volume down when powering on the phone, click install.

That's it, now you have Tow-boot.

Powering on + vol up = eMMC mount over USB
Powering on + vol down = Boot from SD card
Powering on = boot to eMMC
