How do I install LuxeLife on a new hub?

What you need: a pendrive of 4 GB or more (everything on it is erased), a screen and keyboard for the hub, and the hub's network cable. The hub needs an internal disk of 32 GB or more.

Download the installer See the installer's details and SHA-256

Always download a fresh copy. Never reuse an old pendrive or an old file from your computer — an old one installs an old system that cannot be licensed.

Download the installer. In the dealer portal, open Projects, find Image for a new box, choose Intel NUC and press Download installer. The file name starts with luxelife-nuc-flasher-.
Check the download. The file name must start with luxelife-nuc-flasher-v1.0.3 (or a higher number), and its SHA-256 must match the one shown in the portal. On a Mac: shasum -a 256 followed by the file. A different name or fingerprint means an old or damaged file: download again.
Write it to the pendrive with balenaEtcher: Flash from file → choose the downloaded file (no need to unzip) → choose the pendrive → Flash.
Plug the pendrive into the hub, connect the screen, and power on. If the hub starts its old system instead, power on again and choose the USB drive from the boot menu (usually F10 or F12 as it powers on).
Wait for DONE. The screen shows LuxeLife Hub Provisioner, checks the file, names the hub's disk, counts down 10 seconds and installs (about two minutes). When it shows DONE - REMOVE USB AND REBOOT the hub powers off by itself.
Remove the pendrive and power on. The hub starts from its own disk. Check its screen: the top line must say v1.0.13 or newer, with the hub's own password and Licensed: NOT YET. If it shows an older version, the old system is still there — the pendrive did not have the current installer, or the hub did not start from it. Repeat from step 1 with a fresh download. Next: How do I license a hub after it is installed?

One pendrive installs as many hubs as you like. If the screen says LuxeLife is already installed, that hub already has this version and nothing was written: remove the pendrive and power on.
