If I ever feel better.

My personal setup for Arch Linux ARM

# Use your choices of mirrors instead of mine,
# and pack your mirrorlist addition with your script, instead of download it, if possible!
curl -o mirrorlist.cn.txt -R --no-progress-meter https://pastebin.com/raw/RQn0DiVF

## In case you pack it with your script, and can't access Pastebin:
# curl -o mirrorlist.cn.txt.gz -R --no-progress-meter https://wiki.pine64.org/images/9/9f/Mirrorlist.archlinuxarm.cn.txt.gz
# gzip    mirrorlist.cn.txt.gz
# rm -f   mirrorlist.cn.txt.gz

# Insert mirrorlist.cn.txt into pacman.d/mirrorlist at the 4th line
sudo sed -i '4r mirrorlist.cn.txt' /etc/pacman.d/mirrorlist

# Update the packages with those new mirrors
sudo pacman -Syu

# Install more packages
sudo pacman -Syu

# Then:
reboot

Forum discussion:

Latest firmware for PinePhone modem! by Subsentient

About the latest firmware (version number 01.003.01.003):

In a GitHub issue sent by someone who updated their firmware to version number 01.003.01.003, repo owner Biktorgj replies:

There have been some reports of some issues during sleep with the latest firmware, so you might actually want to downgrade to EG25GGBR07A08M2G_01.002.07, which looks more stable.
Plus points, modem-power won't complain after downgrading
