Is the "reboot" option a system cleaner?

Reboot is just a restart.

I hit the screen lightly and it got fixed

So something does not connect and you would have to check the links directly at the panel.

Hello. I am aware of any of you how to turn this radio off. Because despite pressing the "power button" the time is visible on the radio and the side panel is lit. So during the night my battery ran out. I installed them in a Jeep Grand Cheeroke WK / WH

I do not know what installation you have there, if the cables are connected correctly, the radio should turn off after some time after switching off the ignition. Key cables are B +, Ground and ACC. When the voltage drops on ACC then the radio knows that it is going to sleep.

With these cables to connect the Radio it can be different - sometimes it is red + yellow
As the previous speaker wrote, there should be connection and it will be OK

Yes, you are right, these colors on some radios change, so sometimes the radio does not go off when turned off. With adapters, these wires usually have unfastened connectors where the order can be changed.

With the Jeep it is also the case that on two vertical pluses the voltage does not change despite removing the key. I have it connected like this

You have a factory radio, send photos back front and information stickers.

please help with this one, same problem
alt print i not working

Hello my friends!

I also have one such Chinese car multimedia headunit. It came in January, I installed it, it worked properly.
Then last week i changed the battery in the car and when i turned the radio back on it asks for a password. By now I realized this was a screen lock password. Unfortunately I don't know that, this is I didn't that.
I read the forums and would need a recovery reboot. I cannot achieve this in the ways described.
You cannot turn off the radio with the power button. So the power / + VOL combination is not possible.
How to achieve this recovery mode?
Please help my , I would be very grateful.

Thanks to the floating point they have been replaced but I still have to figure out how to run them.
There is a menu where you can check the exact position on the x and y axes of these keys but I don't see the menu where you can turn them on or off.
Now when you touch them, nothing happens as if they were off screen.
Someone something?

Hello. I have been doing radio with a week. I have a Chinese 2-din radio dedicated to vw. Today I got a hard-rest description for Radio QuadCore-R16 Astar_d7, my radio has a Quad-Core A7 processor. I tried according to the description and went into emergency mode at the first attempt.

Android 6 to enter emergency mode (stuck in the boot animation) by connecting the USB keyboard and pressing the "i" key several times while holding down Alt + Print Screen.
After several presses of the "i" button, the device started in the restore mode. Use the arrow keys to go to Clear data / Restore factory settings and Enter to select. I think it will help with many devices with a USB port.

My colleagues finally managed to reset my radio. A simple usb keyboard and quite a lot of time were enough you have to combine it yourself with keyboard shortcuts. I currently have two such radios (I bought the second one to transfer the whole system) look identical but each one has a different key combination so I pressed the keys blindly until I hit. I was able to enter the settings and select the reset options

Hello good afternoon friends

I also have one of those Chinese car multimedia headunits. It came in December, I installed it, it worked fine.
Then in the block settings I put a key pattern which I don't remember and the screen locked. Unfortunately.
I have tried everything but nothing works to unlock it

Please help me, I would be very grateful.

This problem caught up with me too.
I installed the radio and started fiddling with the settings
And zonk
I guess what I changed to the touch because when I touch it in the right corner it is marked in the middle. Touch works all over the world.
I am unable to enter into any options. I have a hard reset but I fail to do it.
There are two power cables constantly connected to the radio one more plus to the ACC after the ignition.
How to trigger a hard reset ???

Hello
I had the same problem.
I was able to turn on the hidden menu and fiddled with the settings resulting in the touch responding in a different place than I was actually pressing.
Because I calibrated with my finger and it was probably not accurate and then it fell apart.
I connected a computer mouse to one of the two USB ports on the radio and with the mouse I easily got to each menu on the radio.
I did the calibration again, but with the help of the mouse and it returned to normal.
regards

In some movies from CN you can see that these radios work "on the table" connected to the power supply. What such a miracle can be attached?

Have you read what is written in this attached picture?
In particular, description 13 - 17.
If you are going to start this radio on the table, you unplug the CanBus module (14,15), connect the connectors 16 and 17 together and give power to the connector 13 as in a standard radio.

Thanks for the info.
That's what I read, but I'd rather be sure. And not all such harvesters have the option to choose whether to connect with or without CanBus. And the connector (16,17) makes a connection that the visitor presents a little differently in this movie .
It supplies the power supply directly to the plug to the CanBus decoder.

Because it is in the case of a car with Can communication, this module is responsible for transmitting the signal to the radio about switching on the ignition.

Hello, can anyone send photos of the USB cable to these Chinese radios, there are cables with 6 and 4 pin terminals, I would need information on which pin comes with which color from the USB socket. I miss a cable and I would like to try this recovery using the keyboard because my radio stops on the Android man and does not want to start. Eunavi radio for Peugeot with tactile buttons on the left side and microSD slot. No knobs. Please reply. Greetings

Give me a photo or an exact model of this radio.

Welcome to the photos again, the radio with which I have a problem is visible

Rather, it will be a standard connection in either the D or E connector.

Unfortunately, after connecting the keyboard as described above, the combination of alt print screen and keys does not work, I think it is connected well because after powering the radio, the keyboard lights up, maybe any other suggestions to get to the recovery menu on the radio that I sent in the pictures above? After pressing the reset button, the radio resets absolutely long holding the button causes the same long period to start the radio, the process does not start until you release the button, when you start the Peugeot logo starts, then the eunavi logo and the spinning android and so it stands unchanged

Help. I entered the factory settings. I was playing and the screen turned 90° and you can see half the screen. Reset did not help

Unfortunately, so far I am waiting for suggestions

On my radio, a five-finger touch activates the touchscreen calibration.
Maybe it'll help.

Well guys, I guess I have a better and simpler solution to this issue.

Check https://youtu.be/Th3AtJNfY88 (no spaces)

It just happened to me on my W219 Android 10 RT3368 radio (model equal to this: https://www.ebay.com/itm/403016169475 - again, no spaces)

I was going through the advanced programmer options (a menu you get in definitions once you press software like 10 times - common thing in android) and I went to change the screen DPs (basically the proximity of the pixels) from 406 to 500 and then I found an option saying "simulate secondary resolutions" or similar. I tried "4k (safe)" and BAM.. my screen looked exactly like the one opening this thread.

I came here searching for a solution, I decided to try the use of external keyboard/mouse and went back to the car.

Once there, I turned on the radio and there it was, again, the very confused screen with overlapping windows.
I knew that if I touched it it would kind of move from one place to another... so I tried to PINCH like reducing an image.. and.. IT WORKED.
Suddenly, ALL "secondary resolutions" got smaller and I was able to, after reducing them to a screen like 1/6th of the full radio screen, place them at bottom right, just by dragging them and access the settings - system - programmer options - simulate secondary resolutions or displays or what is called in English and set to NONE.

And BAM.... screen went back to normal!

So cheers everyone, hope this helps you.

Hi. I also played with resolution and overdid it. I couldn't do anything, the screen didn't respond to touch. I tried by uploading a new software, but there was an error in the 2nd picture. Evidently a bad file on a pendrive. Finally, I connected the keyboard and only because something could barely be seen changed to the previous resolution. Half a day of fight but successful. Best regards and good luck.

HI, my solution works for you for sure.
check it

Just attach a keyboard in USB port 1 and restart the headunit
Use aero key and just disable developer's mood

Hi, my name is Andres, I am from Argentina

I was trying to set something in android tesla style multimedia, and unknowingly got into bluetooth name set. I decided to change it to be able to put my name on it and make it easier to find it

but the bluetooth stopped working completely, it is not visible nor does it allow my phone to connect.

I didn't say the original name and now I don't know what to do. I did a factory reset of the system and deleted all the data, apps, etc but that still doesn't work

any ideas?

sorry for my bad English

car kit is the name I thought it was to be able to make the bluetooth run again

To the radio go two power cables permanently connected + one more plus to ACC after the ignition.

Go into settings and there you have Key learning and teach android + screen calibration.

I have the same problem. Factory reset doesn't fix it. I reinstalled the software and it still didn't improve.
