Yes, checksum would help

But now I guess there are 2 kinds of KD units out there, and flashing the same MCU will result 2 different versions on the about page.
[MTCD Android Head Units General] stefcio007:
Thanks, update went smoothly. Retained all settings and app data.
[MTCD Android Head Units General] Baby.Boy:
[MENTION=1108628]slumpz[/MENTION]

Here's the MD5 checksum results:

dmcu.img: a2 b6 5d 5f 73 47 a9 23 fb ba 60 49 1a e8 85 55

dupdate.img: 15 81 b2 32 86 f3 42 73 0f 53 18 47 bd 7e 0e 09

It's the same as what you have posted before, so I don't know.

And about what you've mentioned, showing the version in the unit; I am not sure about that, because I didn't notice whether it was v1 or v2, but I'll check it.

[MENTION=2238164]stefcio007[/MENTION]

You're welcome.
[MTCD Android Head Units General] gunmoule:
Thanks for your input, we might somehow get to the bottom of it thanks to you!
[MENTION=1108628]slumpz[/MENTION] may have pinned it, if there is two hardware variants of KD units some may not be able to display v2. On mine I flashed countless times v1 and v2 files here, but always end up with v1 displayed on the unit. Btw I never experienced the wifi or Bluetooth problems reported for v1.
[MTCD Android Head Units General] Baby.Boy:
Okay guys, I have just remembered something.

I have bought the unit indirectly, which means there is someone who buys the unit from the manufacturer, and we buy from him.

It's a long story if I want to go through it, but the thing is, the seller talked to the manufacturer about the Bluetooth problem that we had, they gave him a firmware and said update the unit.

But at that time, I already had the v2.06 provided by [MENTION=7499099]pb40[/MENTION].

Since the unit came with v1.92, I assume the version is v2.06, but I have no idea, since I didn't download it.

One more thing, since the seller sold other KD units with v1.92(they are all exactly the same, for one specific vehicle), he had to update them all, because they all had issues, but he used [MENTION=7499099]pb40[/MENTION] firmware, not what the manufacturer provided, because I and my friend tested it, and it was okay.

And now it seems our problems are gone and not any new problems either.

But anyways, I can give you the link of download if you want, the size is 397.2 MB.
[MTCD Android Head Units General] RazGame:
I try read your post twice and... i don't understand you.

U say frimware pb40. What is it ?

You can give link, but whats version this frimware ? It's only MCU or Android ? Any info about this please.

You say problems with Bluetooth. Which problem ? Connection to OBD ?

Upload new version, pls.
[MTCD Android Head Units General] Baby.Boy:
[MENTION=4018808]RazGame[/MENTION]

Hi.

I don't have new version, the manufacturer gave a firmware, which is probably v2.06, but I'm not sure, because I didn't download it.

He just gave the firmware and said update the unit, to fix the Bluetooth problem.

And no, my issue wasn't OBD, I could connect to OBD or my phone just fine, but after a few minutes, they were getting disconnecting.
[MTCD Android Head Units General] RazGame:
You say this frimware have size 397.2 MB, but v2.06_1 and v2.06_2 have 396.7 MB.

Upload it please.
[MTCD Android Head Units General] Baby.Boy:
[MENTION=4018808]RazGame[/MENTION]

Okay, I will give you the link.

But be very careful, as I am not sure what firmware it is!

It should be and supposed to be KD firmware, but I haven't tested it.

Please inform us after downloading the firmware.

Thank you.

When I'm unpack this, it have same size as KD 2.06_2
[MTCD Android Head Units General] pmoral:
Hi, i have this version. I already donwloaded the 2.06_2.

So, How do i update the radio??

I have to put into a pendrive the dupdate.img file or the dmcu.img file??

Thank you.
[MTCD Android Head Units General] pmoral:
I put into the gps card the dupdate.img file and done the update. It took about 20 minutes but when it restarts is still in the 1.82 version :(
[MTCD Android Head Units General] RazGame:
You need flash dmcu.img too
[MTCD Android Head Units General] pmoral:
So, first i update dmcu and the dupdate?

Or i put together the two files in the Sd??
[MTCD Android Head Units General] Baby.Boy:
Put them together and at the same time and it will be flashed.
[MTCD Android Head Units General] pmoral:
Thank you very much. I searched in the forum but didnt find information about or was a bit confusing.

I have the mSD ready so this afternoon im going to update it.

Thank you!!!!
[MTCD Android Head Units General] Baby.Boy:
You're welcome.

Post your questions if you've face any problems.

By the way, I've forgot to mention, since you've updated the ROM already(dupdate.img), you can skip updating it again, just put the MCU file alone in the MicroSD.

But either way, it's fine.
[MTCD Android Head Units General] pmoral:
I did it yesterday.

I was out when i read your message so i did it with the two files inside the sd. It took about less than 10 minutes in total and VOILA! The new version is there. 2.06_2

Bluetooth seems that works better and never "forget" to connect the devices.

The obd is always connected.

Looks like it goes a bit smoother. And now the GPS physical button goes directly to the iGO and not to the Google Maps like before, so really great improvement.

:cool:
[MTCD Android Head Units General] RazGame:
Which app for obd you use? I try torque, but it's don't work for me
[MTCD Android Head Units General] pmoral:
I use torque. But i have to use the version that comes with the radio because if i use a newer one it doesnt work.

With the smartphone no problem with newer versions, but not with the radio. So, is a bit slower but i use the "orignal" that comes with the radio.

I use the elm 327 bluetooth and bought it in aliexpress.

With the 1.82 mtcd version, i had to plug off and plug on because not always was working.

I found out how to change from V2.06_1 to V2.06_2

Go to Settings -> Factory Settings, enter password (126 or m123456), then go to the last tab for the kind of system settings.

From there you can change the version from 1 to 2 or vice versa. I tried to change it from 1 to 2 and back but nothing special happens, except the version show in About screen.

Thank you very much.

Is the firmware different than what was shared in the previous page?

I haven't installed that one yet, so I can't tell.

But this one looks good, specially the DVR app.

Thank you all for providing the updates, it's much appreciated.

[MENTION=1454401]Wout2426[/MENTION]

Your unit seems to be Joying as it's JY, and you should flash their firmware, they are up to date and the firmware is available at their website.

Flashing KD firmware "might" brick your unit, or it "could" work, but since recovering these units are a little bit hard, I wouldn't risk flashing another firmware on mine.

Cheers.
[MTCD Android Head Units General] pb40:
[MENTION=6861316]Baby.Boy[/MENTION]

I think it's the same firmware, the version 1 or 2 is only the customer parameter.

It's better to have screenshots to know the versions.

Could you give my a link to where to find joyous firmware ? I can't find it...

Usually the update files are provided in this topic: https://xdaforums.com/android-auto/...-factory-firmware-rk3188-mtcd-t3366561/page64

But it seems there is no new update for Joying.

And about their website, here's the link: https://www.carjoying.com/Joying-blog/42.html

However, they haven't released any new updates yet, not sure why.

BUT, if you have time, you can contact them, I am sure they will answer you and probably provide you the link to latest version.

Or even maybe the update link is already on the website, but I just cannot find it.
[MTCD Android Head Units General] Wout2426:
OK, thx. My unit is joyous not Joying.

But from what I found it's the same as the Joying jy-ul124, same specs.

I do not want to mess around for now, just looking for in the future. It's working fine now, don't fix it if it's not broken. [emoji2]

[MTCD Android Head Units General] Baby.Boy:
Hello guys.

I have installed latest version without any problems, thank you again.

However it took a very long time to optimize the apps, not a problem though.

The new dash cam app is good, the only thing I would like to be added in dash cam is automatic removal of old captures.

For example when it reaches 5 GB or 2 hours of recording, it should remove the old videos.

I know that there are other apps and I have them, but it's good to have that feature in stock app.

About new fcam app, I couldn't see any differences, I have front cam installed.

There is only one negative thing that has happened.

Yesterday when I was turning on the unit, I realized that the logo has changed and it froze on boot, I couldn't even get the rear cam on the unit as it should always work.

I don't know what went wrong, I reset the unit and it works fine now.

I have changed the customer version, maybe it has to do something with it.

I hope it doesn't happen again, never had that problem.

Finally I have one question.

Does your unit have a remote control? Have you ever tried it?

Mine has a remote control, but it's absolutely useless.

It only works if I point it directly on the IR sensor and no far than maybe 10 centimeters.

Does your remote works well?

Sorry for the long post!

Thank you very much.
[MTCD Android Head Units General] mu5icman:
Hi

I'm running MTCD_KD_V2.16_2 (before MTCD_KD_V2.06_2) and I always experience short interruptions while playing audio (mostely from my music player app called "folder player"). I think it does not happen while listening to radio using the stock radio application. I know that the hardware is limited with only 1GB RAM, but I think these interruptions (I guess around 200ms) happen when there is something working in the background.

Do you also know this behaviour? Is there something I can do to avoid this? Do I have to install a different music player? I already cleaned up as much as possible. I did not root my head unit until now.

Regards, musicman
[MTCD Android Head Units General] Baby.Boy:
Hi. [MENTION=4636229]mu5icman[/MENTION]

I think I have experienced this issue only and only once with stock music player, I thought maybe the problem is the song that I was listening to, other than that, no problem at all, even when playing 1080p video files.

I don't have much apps installed though, however I have dash cam recording in the background always and also sometimes using Torque with music player in the background all together at once.

What I mean is, with all these things together, I don't have any problem.

What I can suggest is to disable gapps. I read this in a topic and everyone seems to be happy about it and they say HU becomes faster.

I know that your problem is not lagging, but it might help, worth trying.

And lastly, it's absolutely makes sense to try another music player, maybe JetAudio or whatever suits you.

P.S.: If you've got some time, please try your remote control if you have it and see if it works well from different angles.

Thank you.
[MTCD Android Head Units General] pmoral:
I also have those short interruptions but they normally are while the system boots. They stop about 2 minuts after booting.

I always have the nav on and torque.

Nothing new for KD ?
[MTCD Android Head Units General] Baby.Boy:
Excellent question! I wanted to ask the same question for quite some time now.

I guess maybe(just maybe) the development on MTCD RK3188 is stopped because of the new CPU(Intel Atom).

Joying was the leader of new updates, but they haven't released anything since last year!

It's the same story with other brands as well, there is no new update for any unit and I am wondering why!

What do you think guys?
[MTCD Android Head Units General] gunmoule:
Last year? The last update on this very thread is February 10, MCU 2.16.

However I guess you are right about support slowly moving to newer platforms like PX5 or Intel Sophia HU's.

On the other hand releases for MTCD_KD have been quite regular, like every 2 months since launch.
[MTCD Android Head Units General] Baby.Boy:
[MENTION=7445662]gunmoule[/MENTION]

Thank you for your explanation.

I don't mind waiting, I just hope they don't give up on MTCD RK3188.

And for the last year...

Well, I was talking about Joying, and if you check their website, you'll see that the last update for MTCD RK3188 is released last year.

So I don't know, maybe they don't want to release the update on their website, but I think that's not the case, since they release updates for Intel version on their website(last update released on 14th March).

So yeah, I hope we still get the updates.

Hello everyone, I have dedicated radio car Peugeot 308, but other manufacturer.

My has Android 4.2.2, I would upgrade to 4.4.4 or better yet 5.1.1.

Can you help please?

I have no experience of these things.

The hardware of my radio and MCU I write them here:

The seller does not know how you update a lollipop. He sent me a bin file to update the MCU.

This is the MCU before the upgrade:

HMI: KUDO.010.2016.10.28.3.50

MCU: TS901.170120

MEDIA: v1.0.0_2016.10.18.5.0

BTV: BT.15.12.01.1040

DVDROM: Nand.152101_860C.050017

This is the MCU after the upgrade:

HMI: KUDO.010.2016.10.28.9.50

MCU: TS-IL.170109

BTV: BT.15.12.01.1040

DVDROM: Nand.152101_860C.050017

Then I installed hardware CPU information to understand what kind of components does my radio and I found that it is jelly beans 4.2..2 and not kitkat 4.4.4. and this is the result:

First time flailer

Morning all, sorry to jump in but hours of searching has not produced an answer. I have been rooting and playing for many moons thanks to all of you, the RK3188 head unit is certainly a new adventure. I have an MTCD_KBT_V2.09_1. Eonon is the seller. I was trying to update the ROM and had a random MCU on the root, rookie mistake, but need some help. It appears that the Interwebs themselves can't find this KBT variant. Anyone have any idea what this is? I thought Klyde, but can't correlate anywhere.

Anyway, if someone knows, or can post an MCU that will help me unbrick, I would appreciate!

P.S. The rerofit in a Range Rover is nowhere as complicated as some would be led to believe. It is quite simple actually. I am glad to help any L322 owners trying to accomplish the same...
