Wow, I cannot thank you enough. Will try these as soon as possible, but I'm downloading them already to be sure I wont loose them.

You kind of ended up in the same situation as me, I've been reading and colecting all software I find but, in my case, prior to any instalation procedure.

Topal Services are not good at all in my language (portuguese), so I would uninstall it if possible. But I disabled it in factory configuration (16176699).

I went back to stock to test Magisk according to the new manual in the other topic. When I try to flash a Magisk patched boot.img I get an error that it is still locked even though I unlocked the bootloader in the dev. options.

When I try fastboot oem unlock I get a message "not implemented" but fastboot oem lock does work.

How do I fix fastboot?

Is this all in the recovery.img and it this a universal image?

If I can sign the update.zip I could also write a new boot.img and recovery right?

Hello, I have a radio on the K4811 platform purchased from Ruancheng on Aliexpress (model A8) - with software from 2023-12-13. I have a problem with the Google Store - every time the radio starts, the Google Store update is downloaded but it cannot be installed. I tried to manually download and install it from apk but the effect is the same - it cannot be installed.

This annoys me because each such download is 60MB of data (every time I turn on the radio), which consumes my mobile internet.

Do you have any way to solve this?

Thanks for the help

I'm also having problems with storage and apps, most apps do not run in the background even though batt. optimalization is off and if I install a plugin for Torque Pro I het the error that torque has not been installed.

Also some settings seem to revert after a reboot. FCC, Agama and Car Launcher Pro (purchased) forget the menu I added apps to.

Hello, I bought a Chinese navigation k4814 sw 20240113 for Honda Civic 8th generation. I installed it, but there is no sound. I tried with factory settings - it didn't work. Has anyone had a similar problem and how to tell if it's a software or hardware issue. I tried with a speaker directly to the speaker cables there is no sound. Only on the RCA for the subwoofer there is filtered bass. The Chinese didn't send me a manual for the cables, so the problem could be in one of them too.

If your front camera is checked in factory settings and you don't have one setup properly that's why you see the black screen after you switch from reverse. Just uncheck it and it will be fine.
[Android Head-Units] mulderfbi:
Hi,

My unit is K4811 NWD 6/128

I am searching for an application to turn on my reverse camera while driving forward or stopped like it was on my previous android multimedia unit. Does anyone have any idea if this could be accomplished with this radio...? I guess the APP should "tell" the radio that it is in reverse so it activates the back view like when you put the car it reverse. I am writing with the seller, but i am not sure he or she understands exactly what i mean...

[Android Head-Units] Jazz3G:
Not work.

I finally noticed this:

With this update.zip the dual dual recording works, but not the USB tethering and does not recognize the 64gb only 31gb.

With this firmware update.zipUSB Tethering works, recognizes the 64Gb. But when I enable dual recording when backing up the image is lost.

If anyone knows any way to brick to be able to tell the one who sold it to me that I change it I would appreciate it or if you have any other update.zip to try.

Thank you.
[Android Head-Units] m00n61:
Did you try to use the update option from the MyCar app? Install an older update zip and the use the online update option to get the right version? Assuming you can find an update for your MCU, that's where the problem is.
[Android Head-Units] Jazz3G:
Yes, I tried, but with each firmware I put only update the canbus version, everything else appears newest. I want to try this file, but I can't create my account for download

[Android Head-Units] Jazz3G:
XD I managed to create the account, but as the file is more than 1gb I don't have enough transfer quota, anyway.
[Android Head-Units] Jubsonmn:
I agree with you, mine in case I can't update the system, it starts to do it but then gives an error and enters the boot screen again and that's it.

I also tried to do the full update when it reaches 45% for everything and restarts, I don't know what else to do.
[Android Head-Units] NeonicFlames:
Im sorry but i think mine is already on k4811_mcx. Or im missing something?
[Android Head-Units] Jazz3G:
You need the file for "MCX". I explain quickly, the versions that are here are for the NWD brand (Nowada?), it can work, but if your radio works well, better not make any changes. I did it and luckily I was able to restore to a JYT brand firmware with the help of m00n61.

Dear all,

According to this post. I am facing the same problem.

Here is my Android Head Unit detail before updating:

I update the system with K4811_NWD_S217206-20230223.zip with other files in flash drive root and these are my screen of the boot loop problem that I am facing:

What I tried are:

put the update.zip to the root of empty flash drive and power on the unit-head

unzip and put all files to the root of empty flash drive and power on the unit-head

try to access to boot menu with RST button but cannot access to it (no matter how long that I press the button)

What can I do to re-install the firmware? Any suggestions are very appreciated.

Kang
[Android Head-Units] tebukan:
Download the 3.7 GB software. Then unzip that software on the computer. Install the file named update there into the flash memory shaped as fat 32. Do these things on the computer. Then, without changing the name of the file, insert the flash memory into the unit's 4-pin USB port and restart the device by repowering it. It will automatically start installing the software. Once the recovery software is fully installed, you can reinstall the update you want.

Do this zip file extraction on a windows computer. Do not do it with a tablet or phone . Remove it with winrar on the computer and put it on the flash memory on the computer. Then it starts properly
[Android Head-Units] pranithan_kang:
Dear m00n64,

I tried OH version and get the same result also :-(

Dear tebukan,

I did the step on MacOS and it is formatted as MS-DOS (FAT32). After I plugged the flash drive to the Head Unit and the error occurred, I found that there are other folders came up with my flash drive.

I then apply tree command to look inside them

I am still stucking with the problem and want some help.

I have the same problem here.
[Android Head-Units] pranithan_kang:
Dear all,

After I managed my flash drive with Windows OS by removing MacOS system directory and files with prefix ._ , I finally came up with successful re-install the firmware.

Many thanks to tebukan's post to point out that I should use Windows instead of MacOS

All kind feedbacks and suggestion were very appreciated.

Kang
[Android Head-Units] fenyovari:
I have been using the device since then, and unfortunately the antenna amplifier is not a 100% solution. When you do not use the car, the device goes to sleep the next day and boots when the ignition is turned on. In this case, the channel settings are preserved. However, if I set something with the system settings, the channels must be set again upon restart or after a reset. However, I found a menu item in the system menu where you can turn on the radio antenna amplification, which also improved the reception.

[Android Head-Units] thugscorpion:
I tried uninstalling the stock launchers when I got root on the device but then it crashes and does not boot.

I have reinstalled the 3.7GB firmware about 10 times now, each taking more then 45 minutes to complete in order to experiment with different updates found here and on 4PDA.

Best is to leave all stock software on the radio because it seems to be hardcoded into Android...

Everithing works! Also, with this last update, the unit can READ (but not write) data from flashdrives. So the problem with apps accessing external storage is solved. I can put videos and music on external storage and the apps can read and work as intended.

I didn't find any cons installing MOD-K4811_OH_S217101.20240222 so far.
