LNURLvault web installer

Flash lnurl-vault firmware onto a LilyGo T-Display S3 or the classic T-Display straight from this page — no PlatformIO or ESP-IDF install needed. The right image is chosen from the chip the browser finds.

Version

Before you start

Works in Chrome or Edge on desktop — Web Serial isn't available in Firefox or Safari.
Connect the board's USB port directly to your computer, not through a hub that lacks data lines.
Installing from this page erases every note on the device. The image is a single blob flashed from offset 0, and the padding between its parts covers the storage area — so a re-install is not an update in place, whatever the erase prompt says. Export anything you want to keep first. To update a device that already holds notes, use a signed OTA image instead, which never touches storage.
If the browser can't find the device, hold the board's BOOT button while plugging it in (or while clicking Install), then try again.

Already flashed?

Use the device console to run the wire protocol's commands (get_info, list_notes, export_secret, ...) straight from the browser and see formatted responses, over the same WebSerial link.
