Nebra · Helium Miner
Nebra Indoor
The Nebra Indoor has a ROCK Pi 4 inside. Flash the PiLoader installer to a MicroSD card with Balena Etcher, boot once, and it installs itself to the miner's internal eMMC — then you remove the card. Your hotspot name is preserved automatically.
ℹ️
Self-installing SD card — no special PC tools beyond Etcher. Your Helium identity (ECC chip) is never touched.
⚠️
One-way install. This replaces the stock Nebra firmware on the miner’s internal eMMC storage.
