Shame on pinephone

[raingloom]

...
And for your information i know pmbootstrap and postmarket OS i use that for Samsung
...

I'm pretty sure pmbootstrap uses a different method for flashing that is Android specific and is not necessary for a PinePhone.
The way I installed pmOS on my PinePhone is this:
-generate disk image with pmbootsrap install
-install Jumpdrive on a microSD card
-insert Jumpdrive into phone
-boot from microSD
-connect phone to pmbootstrap machine
-figure out which entry in /dev or /dev/disk is the eMMC block device
-copy disk image to it using dd

So basically if you have block device access, then there is no need for anything other than dd. You don't have to convert the disk image, you should definitely not format the microSD, etc. Just use dd.

I'm pretty sure you could just dd the image to your microSD, but I wanted to use eMMC, so I needed Jumpdrive. If you want to install directly to the microSD card, then I think you can just do that with dd, but I haven't tried that. But I'm 99% sure it would work.

If you need more help, feel free to ask.
