PPP no longer boots

[MadameMalady]

I just did one last attempt #4 after writing this post and  ... it booted when plugged into laptop. (?)
I did this before and no luck but I also noted battery 3% critically low. When this fiasco started it was 65%.
I was able to install tow-boot to spi and all appears well at his moment. I swapped batteries with my other pinephone
and both charging at this moment. All I'm left with now is a busted sim card slot. later for that.
Adios folks.

So, if you have Tow-Boot on spi, and the phone charges, you're still a-okay.
Charge battery.
Turn off phone
put battery in.
hold power + volume up. when it vibrates release power and keep holding volume up.
once the light is blue, plug into computer.
open disks.
format the emmc of the phone (it's the 124 gb option)
open Balena Etcher.
flash the latest image for the pinephone pro of your favorite release.
enjoy your device.
