| Problem | What fixed it most often | Risk | Reports |
|---|---|---|---|
| Head Unit Shows Only CarPlay? Switch the Box's Protocol | With the box powered and fully booted, press the recessed mode button next to its LED with a paper clip for 2–3 seconds, then release and let it restart in the other protocol. | Advanced | 16 reports |
| Car Doesn't Detect the AI Box After Ignition: Set a Boot Delay | Set a start-up delay so the box boots after the head unit is ready: on a Carlinkit TBox it is in Settings → Other → Factory settings → 4545 → Other → Delay start connection (20 seconds is a good start), on an ApplePie UX999 under Settings → Applepie settings → Boot delay. | Advanced | 11 reports |
| AI Box Keeps Rebooting or Disconnecting? Start With Power | Connect the second power lead of the Y-cable that came with your box to another USB port or a 12 V USB adapter, so the car's data port no longer has to power the box on its own. | Safe | 7 reports |
| Mstick4 "Connection Interrupted" at Random: What Helps | Power the Mstick4 from a second source with a Y-cable whose power plug goes into another USB port or a 12 V adapter, and remove angle adapters from the data line. | Safe | 6 reports |
| "Device Not Supported" After Enabling ADB: Turn ADB Off | Turn ADB mode off again: connect the box to your computer, open its screen with scrcpy, and enter 142618 in Settings → Other → Factory settings until the message no longer says adb, then unplug and connect to the car. | Advanced | 5 reports |
Reports = owners who said a fix worked for them. Risk: Safe is settings only; Advanced needs ADB or an engineering menu; Brick risk can leave the box unbootable. How we count reports.
