🛠️ Installation Guide: Flash via TF Card (SD Card)

The easiest way to install the system to the internal eMMC is by using a TF card as a bridge.

Requirements:

A PC running Windows.
A TF Card (MicroSD) between 8GB and 32GB (Class 10 or higher).
A TF card reader.
SD_Firmware_Tool (Rockchip utility).

Steps:

Prepare the Image: Extract the downloaded .zip file until you have a raw .img file.
Flash the Card: Open SD_Firmware_Tool, select your TF card, tick the “Upgrade Firmware” box, and load your .img file. Click “Create”.
Install to eMMC: Insert the flashed TF card into the Station M2. Power it on. You will see an “Installing system update” progress bar.
Finalize: Once the bar finishes, remove the TF card. The device will automatically reboot into the new Android 11 system.

⚠️ Advanced: Switching Upgrade Storage (Maskrom Mode)

The Firefly Station M2 contains both eMMC and NOR Flash. If you enter Maskrom Mode, the system may default to the small NOR Flash, causing a “Download Firmware Fail” error because the storage is too small.

How to Force Download to eMMC:

If your device is stuck or you accidentally flashed the NOR Flash, follow these steps using RKDevTool:

Download Boot: In the Advanced Function tab of RKDevTool, select your MiniLoaderAll.bin and click Download.
List Storage: Click List Storage to see the detected media.
Erase Nor-Flash: Select SPINOR from the list and click EraseAll.
Switch to eMMC: Select Emmc in the list and click Switch Storage. The status should change from 0 to √.
Upgrade: Go back to the Upgrade Firmware tab and proceed with the full firmware installation.
