UPDATED (June 2021): 17-distro multi-boot image for Pinephone (incl. 3GiB variant)

[recursive_fault]

I don't see anything wrong there. It's pretty much the same as I did - 128GB SanDisk card in a Brave Heart. Perhaps try the verification step on the phone after it boots into Manjaro just in case it's seeing something different?

Thanks wibble.

So, that wasn't my issue, but it got me looking in the right place. What was actually happening was that I had inserted the SD card into the SIM slot by accident. What I thought was the Manjaro OS recognizing the SD card was really the eMMC which was labeled as "SD Card Reader" by the Disks app. My fault for assuming.

Once I put the card into the right slot it worked perfectly. What a cool thing this is. It boots nearly instantly. Really enjoying these images, especially Mobian.
