Finding official firmware links for the YG300 mini projector is notoriously difficult because it is a generic, mass-produced "white label" product sold under dozens of different brand names (like Ledoly, Vamvo, or Salange). There is no single "official" manufacturer website that hosts updates for every version. The Reality of YG300 Firmware
For most users, firmware updates for the YG300 do not exist in the traditional sense. These projectors use simple "SoC" (System on Chip) boards that are rarely designed for user-side software upgrades.
Risk of Bricking: Installing the wrong firmware—even if it is for a "YG300"—can permanently "brick" your device if the internal mainboard version (e.g., CV98, TP.MS) doesn't match perfectly.
Version Variance: There are at least 5+ different internal hardware versions of the YG300. A firmware file for a 2022 model will likely fail on a 2024 model. How to Find Your Specific Link
If you are troubleshooting a specific issue, your best bet is to look for firmware based on the brand listed on your box or the hardware ID in the settings:
Check the Manual: Look for a support URL or QR code in the physical manual that came with your unit.
Contact the Seller: If you bought it on Amazon, AliExpress, or eBay, message the seller directly. They often have private Google Drive links for the specific batch they sold.
Identify the Brand: If your unit is a Magcubic or XGODY variant (common rebrands), you can sometimes find forced flash files on their official blog pages. General Update Process (If you find a file) If you do obtain a .bin or .img file: Format a USB drive to FAT32. Place the file in the root directory (not in a folder).
Insert it into the projector while powered off, then turn it on. Many will auto-detect the update.

Reputable sellers will share a Google Drive or Dropbox link. This is the most reliable method because the firmware is matched to your batch.
