I've tried for a week now. I've followed the ubports install instructions on multiple sd cards and on the emmc using jumpdrive. Nothing works.
I get a ubuntu logo, some non working progress dots, a flickering screen. Sometimes I get to the setup app, it crashes before I can finish.
I had ubports running well on the emmc before the ota img was available, what's gone wrong?
I have the exact same situation.
Unfortunately, I have also been having this same issue since flashing OTA-12. I still have some of the older UT images from April on my machine, and I have no problems at all running them. I tried again last night with a fresh re-flash of one of the newer builds and while it did take awhile to boot into the OS through bootloops and black screens, I was eventually update to #29, but alas, I wasn't even able to boot into the operating system again after that.
At the moment, the newer UT builds are the only images with this issue on my end, sadly (it is the OS I hope to be able to daily drive eventually). I've also tested KDE neon mobile, deb+phosh, and pmOS all with no problems.
... Odd, I have no problems. Outside of the GPS bits being lost in the latest build. I have no issues. Been using Etcher to burn the image to my SD card and the phone boots no problem.
I don't have these problems as well. So far OTA works fine on my PinePhone. Although, it seems that UT is more prone to partition/file system corruption now. It could happen after an OTA or in my case a hard shutdown. In these cases, you will be stuck in a blank screen after the pine64 screen. This is fixable by running fsck on the corrupted partition though.
Also, just to clear to everyone that OTA-12 isn't relevant to the pinephone because its development is separate from the other UT supported devices for now. So basciallyicthere's no OTA-12 for the pinephone.
First time my userdata was corrupted, and this time it was the cache. fsck fixed it for me.
I too am having issues flashing the images. I tried an image as far back as #7 and does not boot. I do not have these issues with mobian nor sailfish or any other distro. Seems to be a ub-port issue.
