Nebra · ROCK Pi 4
Nebra Indoor ROCK Pi 4
The Nebra Indoor with 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.
🔎
Which Nebra? Check the top cover — this one has screws + V-shaped air vents. If it's larger with no vents and no screws → use the Nebra Indoor CM3+ card instead.
⚠️
One-way install. This replaces the stock Nebra firmware on the miner’s internal eMMC storage.

Nebra · CM3+ (Gen 1)
Nebra Indoor CM3+
The earlier Nebra Indoor with a Raspberry Pi CM3+ inside. It boots from a removable “Nebra eMMC Key” card — flash PiLoader to a MicroSD with Balena Etcher and swap it in. No self-install wait. Your hotspot name is preserved automatically.
Nebra Indoor (NEBHNT-IN1)
ℹ️
Needs a thin tool to open the case and a 32GB+ MicroSD that stays installed as the boot drive. Etcher is the only PC software needed, and your Helium identity (ECC chip) is never touched.
🔎
Which Nebra? Check the top cover — this one is larger with no air vents and no screws. If it has screws + V-shaped air vents → use the Nebra Indoor (ROCK Pi 4) card above.

SyncroBit · CM4 Flasher
SyncroBit
The SyncroBit has a genuine Compute Module 4 inside. You'll briefly move it to a CM4 IO board and run the one-click PiLoader Syncrobit Flasher. Your hotspot name is preserved automatically.
ℹ️
Requires a CM4 IO board (~$27, one-time — linked in the guide). Your Helium identity is never touched.
⚠️
One-way install. This replaces the stock SyncroBit firmware on the CM4’s internal eMMC storage.

Linxdot LD-1001
Linxdot LD-1002
⚠️
Not for the LD-1000 — that older model is a Raspberry Pi CM4 and uses the CM4 & Raspberry Pi guide.
Check the model on your label before flashing!
⚠️
One-way install. This replaces the stock Linxdot firmware on the miner’s internal eMMC storage.
