Part 3: How to Identify If You Need This Update

Do not flash blindly. First, verify your device details.

  • Go to Settings → System → About Device → Build Number.
  • If your build ends in 20251110, 20251201, or 20260215—you are on a broken version. Upgrade immediately.
  • If you are on an older, stable build like 20240908... you may want to stay put, but this new fixed version offers better app compatibility.

Step 2: Confirm the chipset.

  • Download “Device Info HW” from the Play Store.
  • Look under “Processor”: must read Allwinner Zq8003 (not Zq8002 or T3). The fix is not cross-compatible.

Step 3: Check your MCU version.

  • In factory settings (password usually 1234 or 000000), note your MCU string.
  • The new firmware works best with MCU versions 5.3.19 through 5.4.12.
