About 5Star GR6
The 5Star GR6 runs on 5Star's factory software, and sometimes you need to reinstall it from scratch. This page provides the genuine stock ROM so you can return the device to its original state. Flashing the stock ROM can clear boot loops, failed updates, a frozen logo screen, or sluggish performance, replacing the system software with a known good copy. File Name: 5Star_GR6_V02_20170802_6.0_SPD.zip File Size: 824 MB Before flashing, back up your data (the process wipes the device), charge above 50 percent, and install the correct USB drivers on your computer. After flashing, allow a few minutes for the first boot. From there the 5Star GR6 should run like a brand new unit.
