Please help

Hello all experts..

I really need help to solve my problem.

I have Kanor 10.1" android 5.1. It works fine until suddenly it stop working. No apps can be started. All of buttons also stop working. The only app works is only the radio and rear camera.

Attempted to get gelp from seller, but no progress.

I couldn't access "About" info therefore I don't know the MCU type installed.

I desperatelly download random update but no change. Then I download KGL MCU. Still no progress. Even now all apps no working, including radio. Rear cam still works.

This is the product I have:

KANOR Android 5.1 1024*600 Quad Core 10.1 inch Double 2Din Car GPS DVD Player Bluetooth Stereo Sat Nav RDS USB WIFI .

Would somebody help me what to do now to make my HU works again? May be someone could teach me which MCU and Update img I should install.

Looking forward to get help very soon.

Thanks in advance.

Regards,

Erick

Is it MTCB/C ? You could try re-installing a ROM using sdfirmware tools.
[MTCB Android Head Units General] Erick1510:
I don't know. I could not acces Setting/about page.

Where can I get sdfirmware tools?

Does anyone have the mcu.cfg of an MTCC KLD6, which has never flashed to MCU KLD9 2.98?

I lost my original mcu.cfg and I’m trying to bring external mic back, since flashing KLD9 2.98 killed it (even if I flash KLD6 2.91-2.97 I got nothing).

Hello to all.

I own an Eonon GA5153F with Android 4.4.4 inside and I encounter some problems with regard to internal memory (too little space to install the APP) and I would like to install a new operating system so that it can also recreate the partition dedicated to the app.

Which system can I install? Is there anyone who managed to install on the Eonon GA5153F Android 6.0 or 7.1?

The data of my car radio are the following:

MODEL NUMBER: S07

MCU version: MTCB-ZD-V2.83

Android version: 4.4.4_22022016

Kernel version: 3.0.36+

root @ chun # 303

Build number: rk3188-eng4.4.4 22022016

CPU: ARM Cortex-A9 @ 1.6GHz (x4)

Memory: 1024 MB

I attach PDF with the data exported from the Droid Hardware Info app

Thanks everyone in advance :)
[MTCB Android Head Units General] typos1:
Eonon are a seller only not a manufacturer, you have an RK3188 ZD MTCB unit - all we need to identify your unit is "MTCB ZD" ,the screen res and the processor (RK3066 or RK3188).

This thread is for MCUs, you are talking about ROMs.

Lollipop is the latest version available for your unit, there is no MM or N available.

There are lots of threads about ROMs, [MENTION=5228031]Johny DJ[/MENTION]'s Lollipop microG ROM is the fastest Lollipop. All custom ROMs have at least 2Gb for apps.
[MTCB Android Head Units General] Gagge89:
hi, I'm sorry, so I'm wrong with the thread? I thought it was the right thread.

I've done a few have the installation of rom cooked on the phone, but I do not know if this is the same thing.

However my processor is RK3188, the resolution is 800x480.

Could I then follow the installation of this?

https://xdaforums.com/android-auto/mtcb-software-development/mtcb-mtcc-firmware-t3632100

It will be enough to install only the ROM or I will have to install other things?
[MTCB Android Head Units General] tariqkhan.co.uk:
You can install just the ROM and as typos1 said johnydj's microg ROM is great
[MTCB Android Head Units General] typos1:
This is a thread about MCUs, you want [MENTION=5228031]Johny DJ[/MENTION]s firmware thread.
[MTCB Android Head Units General] LRail:
Forgive me if this is a dumb question.

I have searched xda-developers and 4pda and cannot seem to find out exactly what the "sleepmode" in darkleo's MCU mod is.

Some posts even seem to imply that later MCU versions all have this functionality.

Is there a site/link/post/thread that explains what benefit you get with darkleo's sleepmode ?

I'm running MTCB-JY-V2.73 now, on a rk3188 unit with 1GB of ram.

I notice that jy 2.86 is also posted.

FWIW: I am in the process of updating to newer firmware on my HU (was using malaysk 4.4.4 from 22-05-2016 but experienced some crashes when trying to use voice commands) and thought that an MCU update may be a good idea.

I assume that firmware choice (4.4.4. or 5.1.1 from booroondook/malaysk/dsa/Johnny DJ doesn't effect which JY MCU version I should use ?

EDIT:hmm... [MENTION=5228031]Johny DJ[/MENTION] stated in a post that with 5.1.1 using the newest MCU is best ? Does that apply to 4.4.4 ?
[MTCB Android Head Units General] typos1:
Sleepmode is delayed shut down, later MCUs had this as standard.

It is usually best to use the most up to date MCU you can find.

But updating the MCU will not help with any crashes using voice commands.

ROM choice doesnt effect what MCU you use.
[MTCB Android Head Units General] LRail:
Great, clear, answer [MENTION=456516]typos1[/MENTION] ! Thanks.

I suspect the consistent crashing of google voice search and cclock was either data corruption or an unwanted update or a combination of both.

Since I'm reflashing and updating the firmware to solve that problem, I figured an MCU update would simply be good maintenance.

As long as Joyous' possible MCU bug fixes didn't introduce new bugs. hehe.
[MTCB Android Head Units General] BogdanFP:
How could one know which CAN bus is good for him? Is there a log/description file to tell what suits best?

For example I have a Suzuki S-cross 2014 and the unit is Klyde kld2 v2.81 that has the can bus setting for GM. There are other can bus setting: mazda vw, etc ...but no Suzuki. Is there any danger if I change the can bus setting? Like bricking the unit etc.
[MTCB Android Head Units General] typos1:
Upgrading your MCU may give more CAN Bus options.

A knowledge of the automotive industry would help too - some cars are simply re-badged versions of other cars and if you know that sort of info you may be able to use other car's CAN Bus settings. Suzuki had a tie up with GM which may explain why your CAN Bus setting is set to Suzuki, although its more likely that at some point you upgraded your MCU without exporting the settings - if you dont export settings then the default setting is GM.

Also, not all units that come with a CAN Bus decoder have a CAN Bus setting, some are simply set to "none", like for the Renault Megane which I mentioned earlir (cant remember if it was this thread or another).

I think its most likely that yours should be set to "none".

Pretty certain you wont brick your unit if you play with CAN Bus settings.
[MTCB Android Head Units General] BogdanFP:
I'm wondering if my wheel buttons will be affected by changing the can bus settings. Almost all of them are working(volume, change radio chanel), except bluetooth answering. These ones are 3 buttons left-bottom of the wheel as in the picture attached.

[MTCB Android Head Units General] typos1:
No such thing as a KLD MTCB/C MCU with a sufix, sounds like you should be in the MTCD forum, not the MTCB forum.
[MTCB Android Head Units General] BogdanFP:
No change. Tried different can buses.
[MTCB Android Head Units General] michLQ:
Can i install this MCU on an MTCD unit?
[MTCB Android Head Units General] typos1:
No - its in the MTCB forum, so its for an MTCB unit, MTCD MCUs are in the MTCD forum.
[MTCB Android Head Units General] michLQ:
Thank you.

Is there an MCU with Sleep Mode for MTCD units?

I think your right. He needs a mtcd mcu.
[MTCB Android Head Units General] typos1:
Yep, youre both right

Youre in totally the wrong forum, look in the MTCD forums, not the MTCB forums.

And pay more attention in future as you could have bricked your unit !

Ok you must have the RK3066 Res 800x480

You will need to goto this thread but please read the OP Page and make sure you are happy with flashing a custom Rom. As the OP don't take responsibility if you brick your units but trust me it's a bit hard to brick them.

https://xdaforums.com/showthread.php?t=3246370

So you will need 4.4.4 800x460 Rk3066 rom August 2017 45.1 version

HI,

I have MTCB KLD HU 800x480 ,

after update to Android - 4.4.4 Boonoorook Tuner does not find FM station anymore.

I found somewhere here, MCU update is necessary,

my unit has acctually ver. 2.02 which is not listed on mega.nz archive upload site, 2.01 and 2.03 as next one.... that confused me a bit.

which MCU shall I flash ?

Can I flash directly 2.78 as mentioned here ?

I don´t want to brick my unit ;)

Hi I just want to validate before I upgrade my MCU . Im currently on MTCB-KLD6-2.77 with stock Kitkat rom 4.4.4 . I want to install the Malaysk 5.1.1 Rom. Whats the minimum MCU I need to do this. From [MENTION=456516]typos1[/MENTION] footer I can see the latest is MTCB-KLD6-2.85. Is it safe to go to this version. I haven't found anyone upgrading from MTCB-KLD6-2.77 which leads me to think it might be custom. Any thoughts before I pull the trigger. Also whats the most stable version is it always latest and greatest. Thanks in advance for your time.

Current Unit spec

•	MTCB–KLD6-V2.77

•	Android version: 4.4.4_11122015

•	CPU : ARM- Cortex-A9 [MENTION=1247388]1.6[/MENTION]GHZ ( x4) #

•	Build: RK3188-eng4.4.4 11122015.20:43:28

•	RAM: 1024MB ( 1GB)

•	Additional info: Its bose compatible ( don’t know if this matters ) and has integrated DAB Module.
[MTCB Android Head Units General] pcmender2005:
Yeah you can here is a full list kld6 v3.06 is the latest version.

https://mega.nz/#F!zRRkVThb!DYBC0LRK-o34ZxDObQo73Q!XNwCna7S
[MTCB Android Head Units General] typos1:
The latest MCU is MTCC v3.06, theres also several later than the ones youve mentioned, such as MTCC KLD9 v2.98 (thats from memory, check the latest on the fileserver) which will make your unit save radio stations without the need for any other app

Back up your MCU settings by going into factory settings and pressing "export", then after changing MCUs you ll be able to restore all you MCU settings.

Theres no cut off point at which you can or cant use ROMs with, basically its best to use the latest version that you can.
[MTCB Android Head Units General] ishan81:
Thanks guys . I read MTCB and MTCC interchangeable. But wasnt sure I should go with the MTCC one. So I should be safe to use the MTCC version on my MTCB-KLD6-2.77. I have a copy of the original MCU just incase and will do export. Will report back once I have done it all.
[MTCB Android Head Units General] typos1:
MTCC is an update to MTCB, so yeah its safe.

You should be able to update to MTCC, you may need to try the latest 4 or 5 MTCC MCUs from 2.97 onwards if some things dont work.

If I remember correctly the best is the one before 3.06.
[MTCB Android Head Units General] ishan81:
One last question . Would you recommend upgrading ROM first then MCU. so you can check functionality is in with 5.1.1 rom . I would assume the MCU would work slightly different with kitkat and lollipop . Or does it not matter.
[MTCB Android Head Units General] typos1:
It doesnt matter which one you update first, but it youre doing both you can update them both at the same time.

Its almost always best to have the latest MCU whatever version of Android youre running.

[MTCB Android Head Units General] matekhr:
Hello,

I have a MCTB headunit running on latest Malaysk fimware.

Recently I noticed that when changing audio source from radio to music, video or navigation I have only heavy cracking sound. A few reboots usually helped to revert it to normal.

When starting my car for the first time in the morning in most cases only the sound from radio is normal.

This weekend i made a fresh clean install of the firmware (two times!) but the problem persists.

So I decided to upgrade MCU image from MTCB-KLD2-V2.77 to V2.81. At first it looks like the problem was solved, but when I started my car today morning, the same thing happened. After a reboot it worked normally, but I don't know what will happen when I will start the car to go home.

Is there any similar experience with such a problem?

Maybe I should use another MCU file. Which one?

Any help is appreciated.
[MTCB Android Head Units General] Marmalux:
Hi,

Actually i have a neighbor that has a Witson branding of a KLD and has something very similar. That is when the device is cold the radio doesn`t work, making very strange noises. After it worms up a bit it starting to work well. This is a hardware issue, there is no software fix. You could just try to open it and look for bad shielding or bad insulation that can go away in certain conditions (like getting warmer).

Also you can try a MTCC MCU. I have a MTCB KLD 6 and had issues with Bluetooth not working well in the same time with WiFi. The solution was to flash a very new MTCC MCu (something like 2.98 or 2.96). After flashing this the radio was not working at all but tried multiple types available in the service menu and found a combination that works. Also the WIFi/Bluetooth issues were gone.... What i`m trying to say is that that new MTCC MCU is very different and might have a fix for your problem.

Hm... I didn't find the correlation between the temperature and cracking noise, but will pay attention to it, if the problem persists. Thanks for advice.

Yesterday I flashed MTCC_KLD9_V2.98 MCU image and had the symptoms just like you said. After I found the combination that works and the car stayed over night, HU worked well in the morning...

After reading a few different threads I'm more confused than ever.

1) Is all MCU's the same or not?

2) Can you flash a JY MTCB MCU on a JY MTCD unit?

3) Can you flash a HA MTCE MCU on a JY MTCD unit?

4) Where exactly can I find the latest MCU for a JY MTCD unit?
[MTCB Android Head Units General] typos1:
Its quite clear - MCUs are not the same, you flash the MCU for your unit (JY for JY, HA for HA etc), you can try flashing a different MCU but you need to read the "Verified Cross Compatible MCU" thread first.

There are a variety of MCU and update threads with MCU in to download.

It doesnt matter whether you have RK3188/PX3 or RK3368/PX5 the MCUs are the same, ie JY RK3188 and JY RK368 both use the same JY MCU, this maybe where you are getting confused.
[MTCB Android Head Units General] R4m80:
Thanx. That clears it up a lot. Like you said, there are a variety of update and MCU threads out there and it can become a little confusing. It would have been much easier if it was all contained in one thread especially if it showed the latest MCU for each manufacturer and which MCUs are compatible with each other, like e.g. JY - 2.62 / HA - 2.71.
[MTCB Android Head Units General] typos1:
I agree but you cant stop people opening multiple threads about the same thing unfortunately, there IS a thread showing which MCUs are cross compatible, its called the "Cross Compatible MCU thread".

Help me please

I do not know if I'm in the right place to share my problem. I'm sorry if I'm not in the right place but I'm a beginner in the car radio field.

I bought a car that has an Android car model S07.

I can not eject a DVD that has gotten stuck inside.

Do you think the problem is software?

If it is software do you think I have to try to update the operating system?

Here is the configuration of my car radio:

Model Number: S07

MCU Version: MTCB-KGL3-V2.68

Android version: 4.4.4_15012015

Core Version: 3.0.36+ root @ ubuntu # 512 Thu Jan 15 12:19:08 CST 2015

If anyone can help me please? Thank you very much.

You can check that the ribbon connector hasnt come out, but it sounds like the DVD drive is broken.
[MTCB Android Head Units General] RemyIhsan:
Thank you for your reply. It's a track. So my problem can not be a software problem? This is probably a material problem?

The DVD playback works very well, it is the CD that no longer ejects.
[MTCB Android Head Units General] typos1:
You may be able to repair the eject function, but its mechanical, so youd need to remove the drive and try and repair it.
