How to Flash an NMminer Bitcoin Solo Miner ESP32 - NOT NerdMiner (Step-by-Step, Real-Time Tutorial)

This video shows exactly how to flash an NMminer from start to finish, in real time, on a desktop.

Looking for NerdMiner V2 instead, watch this:    • How to Flash a NerdMiner V2 Bitcoin Solo M...  

No shortcuts — just the full process so you can see what’s supposed to happen at each step.

This tutorial is ONLY for NMminer devices.

NerdMiner uses a different firmware and flashing process — that video is linked separately.

NMminer firmware requires a license and uses a different setup than NerdMiner.
That license step is part of the process and is covered in this walkthrough.

If you’re having trouble flashing, it’s almost always a cable, driver, browser, or license issue — I cover the basics before flashing.

What you’ll need

• A high-quality USB data cable (not charge-only)
• A PC or Mac
• Google Chrome
• Your NMminer device
• A valid NMminer license

If your computer does not detect the device when plugged in, you’ll need the USB driver linked below.

Notes

• This video assumes your computer is up to date and functioning normally
• Chrome is required — other browsers will not work
• License must be entered correctly for flashing to complete
• If flashing fails, unplug the device, refresh the page, and try again
• Cable quality matters more than people think
