First check to see if you have a compatible version. Flip the unit over and check the serial number. It will start with G290 or 295. This does not work on 28 or 285.

How to Flash
1) Install Rockchip Flash Tools 
2) Download bootloader (rk356x_spl_loader_ddr1056_v1.10.111.bin) attached here. 
3) Boot device into LOADER mode. 

• Plug USB Cable in to back of the unit, powered off. 
• Open the device. With it powered on hold the reset button for 1 second, then immediately let off and hold the recovery button down until the PC recognizes you in LOADER mode

4) Follow the flash procedure found here. 

 

WARNING

 

While I2C/Spidev is functional, i did not install Helium or the Lora packet forwarder for testing. Flash this image at your own risk if you still wish to use helium mining.
