Frequently asked questions
Can NOTE4 and NOTE4C use the same firmware image?
No. The two targets use different display drivers and firmware images. Check the device model for every file.
Does it still need TRMNL after flashing?
Yes. The firmware is a device-side client; content comes from the configured TRMNL service.
