Upgrade modem firmware

wget <link to package.tar.gz>
tar xzvf package.tar.gz
sudo ./flashall

I ran the automatic script several months ago, but updated to newest release manually (see source link), just to be sure.

Upgrade ADSP

According to some people on Pine64 forums, T-Mobile requires ADSP 01.003

Run as root:

wget https://github.com/Biktorgj/quectel_eg25_recovery/raw/EG25GGBR07A08M2G_01.003.01.003/update/NON-HLOS.ubi
echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2
fastboot flash modem NON-HLOS.ubi
fastboot reboot

After properly updating ADSP, my modem stays connected and seems to connect to both 4G and 2G.

Software setup

Proton Mail

Install Geary:

sudo apk add geary

Build and install Proton Bridge, utility that locally encrypts and decrypts Proton Mail:

sudo apk add make git go gcc libsecret-dev libc-dev
git clone https://github.com/ProtonMail/proton-bridge
cd proton-bridge
make build-nogui

Move executables to directory under $PATH:

cp bridge ~/.local/bin/
cp proton-bridge ~/.local/bin/

Configure via CLI interface:

proton-bridge --cli

Login:

• Use your ProtonMail username, not the email alias
• Sync might take a while

>>> login
Username:
Password:
Authenticating...
Account ***** was added successfully.
>>> A sync has begun for username
A sync has finished for username.

Get and save the IMAP/SMTP info:

>>> info
Configuration for antonyak@pm.me
IMAP Settings
Address:   127.0.0.1
IMAP port: 1143
Username:  username@proton.me
Password:  a1b2c3d4e5f6g7h8i9j0k1
Security:  STARTTLS

SMTP Settings
Address:   127.0.0.1
SMTP port: 1025
Username:  username@proton.me
Password:  a1b2c3d4e5f6g7h8i9j0k1
Security:  STARTTLS

Run Geary.

Enter username and password from info above.

In my case, Geary automatically connected to localhost, which is correct.

For me, Geary was very slow, and some emails were missing. Proton Bridge claims to take up to half of all RAM. At this point, creating a service would be a drain on resources. I could write a script to start Proton Bridge

Exit the Proton Bridge CLI

>>> exit

Create a service:

sudo touch /etc/init.d/proton-bridge
sudo chmod +x /etc/init.d/proton-bridge
sudo $EDITOR /etc/init.d/proton-bridge

#!/sbin/openrc-run

name="proton-bridge"
description="Proton Bridge"
command_user="user"
command="/home/user/.local/bin/proton-bridge"
