1. Go to Settings → System → About Device (or Factory Settings).
2. Note down:
   • Android Version (e.g., 10, 11, 12 – note that these are often fake/faked versions; real API level matters)
   • System version (e.g., UI03-00010-)
   • MCU Version (e.g., MTCE_YZ_V3.73)
   • CAN Bus version (if applicable)
   • Build number
3. Enter Factory Settings (password usually 1234, 8888, or 000000) and note the Screen Resolution (e.g., 1024x600) and Touch Panel Model.

Step 2: Find the Correct Firmware

Do not use generic "YT9216CJ" firmware from random forums without matching your specs. Sources:

| Source | Reliability | Notes | |--------|-------------|-------| | Your seller (AliExpress, Amazon) | Best | Request the latest firmware for your exact model. | | XDA Forums (AC8227/AC8257 sections) | High | User-tested, often with changelogs. | | 4PDA (Russian forum) | High (use translator) | Largest repository, but navigate carefully. | | Random blog/Youtube | Low | High risk of malware or wrong files. |

Filename clue: Look for files named update_auto_*.zip or HA3_*.img. Ensure the resolution (1024x600, 800x480) matches yours.
