    Tested and working 1.1-1.7 TH/s Outer case may have scratches and dings. FW 7.2.1 installed Firmware downloads. SP20 SD Reflash Firmware - Google Drive download SP20 2.7.1 Firmware Instructions: SP20 SD Reflash Firmware: First you will need Win32 Disk Imager. Download the SP20 SD Reflash RAR file. Use the Win32 Disk Imager to install the IMG file on your micro SD card. Once installed it may ask you to format the SD card. Just exit out of those prompts. Now when you look at the files on the SD card there should be 7 visible (upgrade, autorun, MLO, Spondoolies.dtb, u-boot.img, ulmage, unbrick). You can now plug your micro SD card into the SP20 while powered off. Once installed power the SP20 on. The yellow light should turn on briefly then turn off. After about a minute it will begin flashing yellow and green back and forth. You can now power off the SP20 and remove the micro SD card. Turn the SP20 back on and it should now be flashed back to default firmware. Once you log in (admin / admin) it should be at the agreement page. You are all done.
