    in version 8.1 the default code is 8888, try it.

    When it comes to these Chinese radios, they usually have codes like 1111, 2222, 1234, etc.

FAQ

TL;DR: One verified code—000000—unlocked the service menu on a Chinese Android 9.1 head unit; "code 000000 helped" confirms it. Use it when other codes fail. [Elektroda, 76slawek, post #19004788]

Why it matters: It quickly solves "how do I change my boot logo or access hidden settings" without hours of guesswork.

Quick-Facts:

Quick Facts

What service code finally worked for a Chinese Android 9.1 head unit?

The confirmed service code was 000000. The OP reported, "code 000000 helped." It unlocked the service menu on that unit. Models vary, so results can differ. Try this code early if common lists do not work. [Elektroda, 76slawek, post #19004788]

Will 8888 work on Android 9.1 radios?

8888 appears as a default on many Android 8.1 Chinese radios. Simple sequences like 1111, 2222, or 1234 also occur. For Android 9.1, these may not apply. Use them as quick first attempts, not guarantees. [Elektroda, roxio, post #18971667]

What common service codes should I try before contacting the seller?

A 37-code community list circulated with examples like 12580, 3368, 121212, 126, 7253, 5839, 3506, and 7890. Test these quickly to rule out defaults. Keep notes to avoid repeats. Prioritize short, simple patterns first. [Elektroda, JayRo, post #19000768]

None of those codes worked—what next?

That happened here, where none of the suggested codes matched the unit. When stuck, share clear photos of the UI and labels. Ask the seller for the code, even if responses lag. Post firmware and model details to aid identification. [Elektroda, 76slawek, post #19003925]

How do I access the service menu on this type of head unit?

Follow three steps:
  1. Open Settings and locate the service or factory menu entry.
  2. When prompted, enter 000000 as the service code.
  3. Change only what you need, such as the boot logo, then reboot. [Elektroda, 76slawek, post #19004788]

Can the seller help with the service code?

Seller support can be limited. In this case, the AliExpress seller did not provide the code. The OP noted the seller "didn’t talk." Community findings solved it instead. [Elektroda, 76slawek, post #18995043]

Do wrong code attempts cause any harm?

Here, repeated wrong codes simply failed to unlock the menu. No reset or brick was reported during attempts. Change only necessary options once inside to minimize risk. [Elektroda, 76slawek, post #19003925]

What about codes like 5678 or 7890?

They were suggested and tested. The OP confirmed they did not work on this Android 9.1 unit. If they fail, continue testing other options. [Elektroda, 76slawek, post #19000714]

What’s the purpose of the service code on these units?

It unlocks the service menu, where hidden options reside. In this thread, the code was sought to change the boot logo. That required access beyond normal settings. [Elektroda, 76slawek, post #18972042]

Is 000000 universal across Chinese head units?

No. It worked on the Android 9.1 radio discussed here, but other models differ. Try it early, then continue with other candidates. [Elektroda, 76slawek, post #19004788]

Any quick tip to prioritize which codes to try?

Start with defaults known for similar versions. For Android 8.1, try 8888 first. Then test simple sequences like 1111, 2222, and 1234. [Elektroda, roxio, post #18971667]

Should I post photos or firmware info to get help?

Yes. Clear screenshots or photos can speed identification and advice. As one post put it, "If you don’t, no one will help you." Share UI, model labels, and versions. [Elektroda, 76slawek, post #18976497]

Where did the big list of codes come from?

A member shared a list downloaded from a foreign forum. It contained 37 candidate codes across multiple lengths. Use it to triage quickly before escalating. [Elektroda, JayRo, post #19000768]

Does the Android version matter for service codes?

Version can influence defaults. A member noted Android 8.1 often uses 8888. Expect Android 9.1 devices to need a different code. [Elektroda, roxio, post #18971667]
