This guide will show you how to flash the latest Firmware provided by Nebra via Nebra HUB.
What you will need
OS image zip folder specifically for your Indoor/Outdoor hotspot (provided by Nebra). (Please follow the link HERE and then select which version of miner you have, outdoor, indoor, or RockPi ) & No need to unzip it (See Step 2).
MicroSD card (32GB & Class 10 minimum) (Please make sure to back up any existing data on the SD card you will use as writing an image to it will completely wipe the card)
SD card reader
Do NOT flash Nebra hotspot unless instructed by a member of the Nebra support staff.
Sharing the OS image with another person will corrupt that person's Hotspot and your Hotspot and will prevent any future OTA updates. The image provided to you has been specifically configured for your Hotspot ONLY.
