The Seller: Reach out to the store where you bought the unit; they often have a private Google Drive link for updates. 3. Preparation Requirements

A USB Flash Drive: Use a high-quality drive formatted to FAT32. Avoid drives larger than 32GB, as some head units struggle to read them.

Firmware Files: Usually, these come in a ZIP archive. You will typically see files named XYAUTO_UPG, metazone.bin, or similar.

Stable Power: Ensure your car battery is healthy or keep the engine running. If the unit loses power during the flash, it’s game over. 4. The Update Process (Step-by-Step) Method A: The Standard Update

Extract the files: Unzip your firmware and move the contents directly to the root of your USB drive (don't put them in a folder).

Connect: Plug the USB into the 4-pin or 6-pin USB port of the head unit.

Trigger: Most YT9218C units will automatically detect the update. A pop-up will ask, "Start Update?" Select OK.

Wait: The unit will reboot into a "green text" recovery screen. Do not touch anything until it finishes and reboots back into the Android home screen. Method B: The "Force" Update (If your unit won't boot) If your screen is black or stuck on a logo: Plug the USB drive in. Use a paperclip to press the RST (Reset) button.

As the unit reboots, repeatedly tap the screen or hold the power button (this varies by manufacturer) to trigger the flash mode. 5. Post-Update Checklist
