Step 1: Download the latest firmware package for your device. Here is a list of both Droidplayer and Gostreamer firmware
Step 2: Extract or unzip the package to a clean SD card. Your SD card should now have 3 files.
Step 3: Plug your SD card into your player and open up Reboot Manger from ALL APPS
Step 4: From here, scroll down and choose Reboot Recovery
Step 5: Choose Yes to confirm
Step 6: Now your system will reboot into the recovery console and begin to install the firmware you have put onto the SD card. And you are done!
