not booting from sd card

[quixote]

I downloaded ubports from here: https://ci.ubports.com/job/rootfs/job/rootfs-pinephone/ (Chose .img.gz under "Latest Successful")

Extracted to default .img file

put on sd card using:

Code:

sudo dd if=/home/user/file.img of=/dev/sdX bs=1M

Put it in the top (sd card) slot in the phone next to the battery. There is no SIM card in the phone yet.

And when I turn it on nothing happens but the screen with the factory test. (Everything passes factory test except EG25, because no sim).

Possibly the battery is really low? (I did remove battery protection tab.) How do you tell? I don't see any indicator lights showing charging or battery level and I can't find the info here or on the web.

Hope you can help!
