no, what I asked is, if when the multimedia is connected to a computer, does it apear as a usb device ?

i've tried 2 units, with both the 4 and 6 pins rear usb connectors, and they don't appear on my computer as a usb device, so I cannot send adb commands
[Android Head-Units] Oldbiggy:
Doesn't it show up as an unknown device in the device manager on your computer?
[Android Head-Units] pencilgon:
nope, I'm using a Debian 12 system, the command lsusb does not show anything new when I plug in the device, with both the 4 pin and 6 pin ports
[Android Head-Units] Jubsonmn:
still doesn't connect the multimedia to the computer, neither to the 4-pin nor the 6-pin port

hello

What is the difference between k4811 NWD and k4811 OH versions?

What languages are in the OH version?

I nead Lithuanian language.
[Android Head-Units] Jubsonmn:
hello everyone, I'm new here and it seems that only here has information about the K4811.

Comprei um K4811 no aliexpres na Ruancheng, mas depois de um tempo meu aparelho começou a reiniciar toda hora, entrei em contato com o fornecedor e ele me mandou um arquivo UPDATE para inicializar pelo USB, fiz todos os passos que ele me mandou mas o aparelho não está inicializando a partir do USB ao ligar a fonte de alimentação. Minha pergunta é como ligar a unidade inicializando a partir do USB? e tenho mais uma duvida que li aqui no forum onde digito a senha do desenvolvedor (345543) ?

I thank you all sincerely.

Hello friend, you will likely get more support if you post in English. I tried google translate and here’s what I get:

“I bought a K4811 on aliexpres on Ruancheng, but after a while my device started restarting all the time, I contacted the supplier and he sent me an UPDATE file to boot from USB, I did all the steps he sent me but the device not booting from USB when plugging in power supply. My question is how to turn on the drive by booting from USB? and I have one more doubt that I read here in the forum where I type the developer password (345543)?”

Your best option is to ask the aliexpress vendor how to boot from usb. It is not a normal operation to boot from usb.

Maybe some other experts here can help using the English translation.
[Android Head-Units] Jubsonmn:
I had posted in English but I think my browser translated it again to Portuguese which is my language, but I will post again.

For Developer Password-

In -Setting, -About Car Device, tap "Build Number" 7 times and the password prompt will appear.
[Android Head-Units] Jubsonmn:
Thank you very much, I managed to enter developer mode, and I saw that the USB boot is already active.

The problem is that I am not able to boot from USB, I already formatted the pen drive in FAT32, and put the UPDATE file, but it doesn't work.
[Android Head-Units] Jubsonmn:
yes, the seller has also given me these procedures that you mentioned, but in my case it is not working, when the update is made an error appears and it restarts, then the seller gave me another complete update of 3.7gb, but when I turn on the multimedia with the USB it does not boot from the USB

1. Use a computer to download this upgrade software, its capacity is about 3.7GB,

2. Unzip to get the update folder (see video)

3. Copy the folder to the root directory of U disk;

4. Connect the U disk to the radio and run it automatically. It takes a long time to update. Please wait patiently.

Watch:

1. Insert the U disk into the 4-pin USB port, refer to the picture in the mailbox

2. Turn off the power first, then turn on the power again, and it will automatically enter recording mode.

Good afternoon, I need a help with this, this is the data I have, I see that some have a version dated October, where could I get it? And if it is not possible, then how can you do the factory reset, the first time I did it with the code 3368, but now it does not want to accept it. Thanks, in advanced.
[Android Head-Units] S2artb:
Factory reset code is 1234

All codes I have are:

[Android Head-Units] Jazz3G:
Now the problem is the 4-pin USB, I have to put the USB, but it does not recognize it at all, the 6 if, but from that does not boot. Someone knows what to do? before the reset it worked, but I know that I had touched some option in the factory setting, but I don't know which option.
[Android Head-Units] Jazz3G:
Any way to put the version for K4811_JYT I put the December version but now I can't see the back up camera or the dual recording app. XD Help me please. Now the version is K4811_NWD :C.

[Android Head-Units] vitkyyyse:

Anyone who has K4811 versions NWD, OH and others, can you check in the settings which languages you have, if Lithuanian is available.

Thank you very much to those who will watch.

[Android Head-Units] tasmak25:
If i understand correctly the word "Lietuva", it looks like yes my friend. Version OH Sep 2023. If u dont see it in settings, you need go to Factory Setting, code 16176699 and under languages you check the box under the language u want to add. After reboot, u should be able to select from initial settings.
[Android Head-Units] vitkyyyse:
Yes, namely "Lithuania".

I have the NWD version of K4811, but there is no Lithuanian language in the 16176699 language settings.

Do you have the OH version of K4811 in Lithuanian?

[Android Head-Units] M.Aziz:

[Android Head-Units] vitkyyyse:
I entered the OH version of k4811 just because of the Lithuanian language which is not in the NWD version, but the 'update' file is not the entire software, and after changing the language, the language changes only in the android settings, which is because the hardware remains the original NWD version even if you update the OH version.

After upgrading from the K4811 NWD version to the K4811 OH version, the original NWD version is still displayed in the android settings....

How would it be possible to save the full K4811 OH software instead of the K4811 NWD software to change the desired language in all menus???

Hello,

car: Meriva B 2017

system: K4811_NWD_S218104.20230928.161335

version: 8GB RAM 2k screen

In my car at beginning steering wheel buttons where messed up. Using My car --> learning after changing voltage difference to 200 mv I could only change one key on the wheel. Other things as AC, control panel on dash board with multimedia etc. was working fine.

So I tried to upgrade CAN in MyCar --> Upgrade --> Check and right now there is no connection between the car and android.

My previous versions:

My current version:

View attachment 6054828

This CAN Check for updates is in the never ending loop.

What could happen?

Should I install this CAN using pendrive?

What could be the reason my steering buttons were not working correctly. Thanks!

It seems that the K4811_OH_S217101-20231030_3.7Gmagisk rooted firmware could be found on this russian telegram channel, I'll be uploading it here for future reference.

I've not tested it yet, so use some common sense and caution if you are playing with this stuff

the procedure is to unzip the contents,

1) move the update folder to the root of the thumbdrive

2) shut down and remove power to the unit

3) use the thumbdrive on the 4 pin usb connector

4) restart the power and the unit

5) wait for a while, it seems, maybe pray....
[Android Head-Units] enzo60:
But why are you always looking for updates for the K4811? If you have a working version of everything, leave it. Did you know that overwriting other firmware can cause unrepairable errors?​
[Android Head-Units] tallaploomi:
Hi,

What you guys use for auto screen brightness, i have no option nowhere to use auto brightness only manual setting i have NWD.

And of course the radio signal is awful, has anyone installed radio signal amplifier ? Does it make things better or not, when on the road its almost impossible to use the radio, AF of course does not work just starts scanning stations.Ive tried everything thats possible but no help just used how the original radio switches to new frequency seamlessly when along the road.
[Android Head-Units] pencilgon:
I wanted a magisk enabled rom, I didn't test it yet, but if it works I won't change it in the foreseeable future.

right now my unit is just a toy as I'm testing it at a bench, I want to know the possibilities and see what can be done/changed/adapted/configured, in a few weeks it will be installed in my car and then it will be a tool and be kept as unchanging as I can make it to be.

I'm aware of the chance of bricking the device as I've bootlooped one unit after flashing a broken boot.img that I made, but I'm a software developer and electronics tinkerer and breaking toys is just a part of life, you know the maxim "if it ain't broken fix it till it is".

I've been testing stuff on this head unit for a month now and already have a good idea of exactly how I want it to behave and what can be done, I probably could have left it at stock configuration and be mostly happy, but I'm sure that a few of the quirks in the stock rom would bug me to no end.

The other firmware and apks I've downloaded just to test and collect, maybe I'll upload it to mega and share a link someday.

I came to the conclusion that my multimedia cannot be repaired anymore, because when the Android is frozen, the power is not supplied to the USB port, so there is no way to recover the Roms.☹️☹️
[Android Head-Units] pencilgon:
did you try to make a USB cable for the 4 pin connector that you found ? that could be a solution, not sure as I didn't try, If you build the cable use a USB tester or something that you can fry before plugging it to a computer :).

I've fried my old unit by putting 12v over a wire that could not handle 12v ( blown up a capacitor, probably I'll try to fix it someday, or at least I'll have a spare screen if mine ever broke.

I wasn't able to enter recovery mode, but you might get luckier, what I tried was.

The five finger method,

a) turn everything off

b) connect power and pull 12v to the ignition wire to turn on the unit

c) press the RST button for a few seconds

d) release the button and tap the screen with five fingers for a while

I've also tried every method described here without luck

Android Recovery reset for Head Unit with no buttons.

This article can help guide you to accessing the Android Headunit recovery partition that can help solve some android boot loop problems.

android-headunits.com

I've tried pressing the RST button for something like 40 seconds to see if some light would blink, no luck there also

I've also tried something like the five finger method but tying the Key1 cable to ground, also tried with Key2 cable to ground, be smart when trying random stuff use a resistor to limit current, I've used a 1k ohm ( chosen randomly from parts I had on hand )

as I said, no luck whatsoever getting it to enter recovery mode, I know it exists because from a working unit I can reboot to it via the terminal, but no luck getting adb to work so I cannot use a computer to put the unit in recovery mode.

If you live in Sao Paulo, search around Santa Efigenia to see if you can find a electronics repair shop.

Em relação àquele conector que mencionei, fiz as medidas de tolerância e realmente é um conector USB, mas é um salto para o conector de 4 pinos, fiz um cabo para conectá-lo ao computador mas não aparece nada no PC.

Também segui os passos do site que você recomendou, mas também não tive sucesso.

Conversei com o vendedor chinês sobre a placa que não funciona, ele me pediu para mandar para conserto na China, mas não sei se é viável devido aos impostos.

Aí perguntei se ele vende só a placa-mãe e ele disse que custa 70 dólares mais frete de 20 dólares, então tem mais impostos mas não sei se vale a pena comprar outra.

Regarding that connector I mentioned, I took the tolerance measurements and it really is a USB connector, but it is a Jump to the 4-pin connector, I made a cable to connect it to the computer but nothing appears on the PC.

I also followed the steps on the website you recommended, but it was also unsuccessful.

I talked to the Chinese seller about the board that doesn't work, he asked me to send it for repair in China, but I don't know if it's viable due to taxes.

Then I asked if he sells just the motherboard and he said it costs 70 dollars plus shipping of 20 dollars, then there are more taxes but I don't know if it's worth buying another one.

Hi,

I love this little community, tanks a lot of this useful info.

I bought an NWT unit in May 2022 and couldn't find any info at the time. I did read all this pages I need to make some time to update mine, it has a 2021 SW on it but I'd like to know if somebody figure out a way around low low volume from nav app when mixed with music ?

Also I cannot use polarized glasses with my unit, I wonder if all are the same. Mine is supposed to be IPS.

Is it any way to get some DSP saved profiles? ( Ex: PoP, JAZZ, Voice ) ?

Also is it any way to zoom or increase character size? I have this option, I already maxed out and is not enough to see maps when driving. It has to be something with display dpi but couldn't find anything in settings ( factory, or android )

Hello! I have a 7' A6 4/32 Gb device. It has Android 11 on it. My problem is that the sound of the navigation is much quieter than the sound of the music (radio, youtube, web radio, etc.) I can't find the solution to set it up. Please help!

- After reset, the sound of the navigation was improved. I don't know what could have happened! However, I encountered another problem: My phone does not play music via bluetooth. After connecting, you cannot see the music on your phone. How can this be solved?

I installed the latest firmware that the device can download. Everything works fine. Bluetooth also plays music from the phone. I couldn't get Carplay to work, it didn't connect in any way, neither via cable nor wifi nor bluetooth. The sound of the navigation with Waze is still weak. Google map is better. I'm still trying to make everything work, but it's a game of patience.
