   • Go to Settings > About Device.
   • Note the Build Number and Kernel Version.
3. Hardware Differences:
   • LED vs. LCD Logic: Some YG300 units use different WiFi chips (Realtek vs. MediaTek). A firmware update will not fix hardware limitations (e.g., if your unit physically lacks 5GHz Wi-Fi, firmware cannot add it).

4. Step-by-Step Update Process

If you have obtained a "verified" firmware file (usually an .img or .zip file), follow these steps.

Requirements:

• A MicroSD card (formatted to FAT32).
• A card reader.

Procedure:

1. Prepare the SD Card:
   • Some firmware requires you to copy the file directly to the root of the SD card.
   • Others require the SD card to be "burned" with software like PhoenixCard or SDDiskTool (common for Rockchip processors). Check the README file included with your firmware download.
2. Insert the Card: Turn off the projector and insert the prepared MicroSD card.
3. Enter Recovery Mode:
   • This varies by unit. Usually, you hold the "Power" button and the "Menu" button simultaneously, or simply turn the unit on with the card inserted.
   • If the firmware is correctly formatted, the screen will display an Android logo and a progress bar.
4. Wait: Do not unplug the power or remove the SD card during this process. It can take 5–10 minutes.
5. Reboot: Once the progress bar reaches 100% and the unit reboots, remove the SD card.

Installation Procedure

1. Format the SD Card: Use FAT32, default allocation size.
2. Extract Firmware: Unzip the verified package. Look for files like YG300_UPDATE.img, recovery.img, or factory_update_aml (depending on chipset—Rockchip or Amlogic).
3. Copy Files: Place all extracted files onto the root directory of the SD card. Do not put them inside any folder.
4. Power Off YG300: Disconnect from mains.
5. Insert SD Card: Into the designated slot on the YG300.
6. Enter Recovery Mode:
   • For most YG300 projectors: Press and hold the “Power” + “Volume Up” buttons simultaneously while plugging in the power cord.
   • For dongle versions: Use the pin-hole reset button while connecting USB power.
7. Navigate Recovery Menu: Use volume buttons to scroll to “Apply update from SD card” or “Install from external storage.”
8. Select Firmware: Choose the .img or .zip verified file. Confirm.
9. Wait: The installation takes 3–7 minutes. Do not unplug or press any buttons.
10. Reboot: After “Install from SD card complete,” select “Reboot system now.”

First boot may take up to 5 minutes. If stuck on logo, power cycle once.

Boot Loop After Flash

• Fix: Hold L + R + Start during boot to enter recovery mode. Flash again. If that fails, your hardware revision may require a different verified build.

Post-Flash: Verifying Your Installation

After the update, verify that the installation worked:

1. Go to Settings → System Info. The version number should match the verified release.
2. Load a demanding game (e.g., Super Mario World on SNES or Sonic the Hedgehog on Genesis). Check for audio sync and frame rate.
3. Test the save state function. Create a save, power off, and reload.

If all three pass, you have successfully installed YG300 firmware verified.
