Prepare the TRMNL service
Device firmware fetches images from the configured TRMNL service. Prepare the service and monochrome NOTE4 N16R8 hardware first.
Make a full backup and select files
Save a 16 MB Flash backup. Select only the zectrix_note4 target in the zectrix branch. Distinguish the merged image for first installation from app-update images for compatible partition layouts.
Connect Wi-Fi and display a dashboard
Complete USB installation and first boot using the selected version's instructions, then connect Wi-Fi and TRMNL. This site has not checked current release files and does not provide direct flashing.

Frequently asked questions
Does it include a ZECTRIX factory recovery image?
The listed TRMNL release notes do not include ZECTRIX factory firmware. Save a complete backup of your own device before installing.
Does this version support the four-color display?
