No idea what unit you have but its DEFFO not an MTCB unit, youre in the wrong forum, try the general Android head unit section.
[MTCB Android Head Units General] magik79:
Thank you
[MTCB Android Head Units General] Luv-Kush:
Why do all that when you can just install convolver (samsung live) in viper4android of your taste. Have been using that for a great bass,treble sound and never thought of messing with hardware.
[MTCB Android Head Units General] buzzland:
I also have a MTCB-ALS-V2.18 release. I flash the rom by KGL and now my steering wheel buttons not working and the front panel button is no longer the same. Anyone have a solution for me?
[MTCB Android Head Units General] typos1:
Yes, it seems you have not read the wiki correctly and have updated both the ROM and the MCU from KGL - as has been mentioned numerous times, you cannot use an MCU from another manufacturer (with the exception of BN and HA units), ONLY the ROM. "ALS" is a new manufacturer and therefore there are no ALS MCUs available here, you will have to speak to your supplier/manufacturer to try and get the correct MCU for your unit.
[MTCB Android Head Units General] buzzland:
Yes you right I should have read better but I am bad in English and I had not quite understood. Is it possible that a person in the same rom as I can extract it and send it to me because when I contact the seller he told me to return the item and it is not possible .
[MTCB Android Head Units General] typos1:
It is NOT the ROM that is your problem, it is your MCU, MCUs cannot be extracted from MTCB head units, as I said you ONLY have 2 choices here, either get an MCU from your seller/manufacturer or find one from here or another site like 4pda.ru for instance, there is no other way I am sorry. Once you have got the MCU you just flash it to your unit, the ROM can stay as it is, when updating ALWAYS make sure you know what you are updating - if you do not want to update your MCU, then remove any MCU you may find in an update and update only the ROM. And read the wiki, use a translator, but read it !

What does the settings/about device screen on your unit say now ?
[MTCB Android Head Units General] 81greg:
can anyone point me in a direction for info on mcu version mtcb-zd-v2.86 i wanta update my sytem i see malesky has a nice rom but what about this mcu i dont see it mentioned anywere except other people asking samething what is this?
[MTCB Android Head Units General] typos1:
ZD units are rare, ask your seller, but v2.86 is pretty up to date anyway.
[MTCB Android Head Units General] Mr Bigglesworth:
Viper4android didn't do anything for my head unit, changing the eq didn't do anything. Wondering if I had the settings wrong (defo had installed driver). Can you tell me what settings you are using?
[MTCB Android Head Units General] typos1:
Search the old thread, there are detailed instructions on how to use it.
[MTCB Android Head Units General] Luv-Kush:
Here is the apk I used https://app.box.com/s/cvgmepvl57upu7d0xfb1zixkuatcvvbz and also irs https://app.box.com/s/um1gze7i9yurvjdk1ufi5mv7kzjog0t3 . But it only works apps you install not the system apps (radio).
[MTCB Android Head Units General] typos1:
The real Viper4Android works with the built in MTC Music app, there is a fake Viper doing the rounds, get Viper from the official site :

If anyone is interested, here is a link to ZD v.2.92 MCU (not tested) :

[MTCB Android Head Units General] masri1987:
I bought this unit

http://xtrons.com/pf75m211a-7-andro...irroring-function-obd2-for-mercedes-benz.html

Rooted it and Installed V4A straight from their website, sometimes it doens't turn on until i launch it sometimes it works fine, major difference though! I use V4a on all my android devices so i'm well versed in it.

But i'm having a problem, this is my MCU version

I have the notorious bluetooth obd "turning on bluetooth" bug.

As I understand it only the May and June MCU updates resolved this?

But i don't know if the GS 2.55 is the right one for me? What happens if i mess up?

I need some direction, thanks for your expertise
[MTCB Android Head Units General] typos1:
With MCUs its easy to just flash another if it messes things up.

I would strongly advise an MCU update because your MCU is over 2 years old and you are using it with L, the latest version of Android.
[MTCB Android Head Units General] masri1987:
Okay, how is it 2 yrs old? It's dated Apr 2016?

How do i backup my current MCU? I have root if that helps.

Any fixes I can do to resolve the obd2 bluetooth turning on freezing problem?
[MTCB Android Head Units General] gk66:
You have an MTCD not MTCB device. You're MCU is likely the latest. You should try the specific MTCD forum for advice from owners of the same type unit.
[MTCB Android Head Units General] typos1:
Doh !! Silly me, I didnt spot it was MTCD !! How could I have missed that ?

Youre in the wrong thread [MENTION=2694397]masri1987[/MENTION], as [MENTION=7163951]gk66[/MENTION] says you want the MTCD forum.
[MTCB Android Head Units General] masri1987:
Thanks guys, I've been over there requesting the same input but getting no traction.

I've reached out to manufacturer and seller and getting radio silence too. i'll be patient i suppose
[MTCB Android Head Units General] Mr Bigglesworth:
Ahhh, maybe there were issues with the one I was trying. And I may have been focusing on MTC apps.

So would V4A work with DVD app? I see that Luv-Kush says it won't work on Radio.
[MTCB Android Head Units General] typos1:
If I remember correctly MTC music is the only built in app it works on, but not when you have the "visualisation" (the graph that moves with the music) on. Do a search of the original thread, theres full instructions in it, I m pretty sure it was [MENTION=3744488]devilsoft[/MENTION] who wrote them, just a case of finding them.
[MTCB Android Head Units General] devilsoft:
The V4A works only with MTC Music, MTC Bluetooth and any non-MTC app. MTC Radio and MTC DVD is using a separate audio output, which could not handled by V4A. For MTC Music to work, you need to disable the graphs.

For more details, check this post and this post.

Read the wiki and check your settings/about device screen".
[MTCB Android Head Units General] Vrchnak:
Hi,

I'm not sure which part of headunit is responsible for this function so hopefully I'm on right place.

I have device EONON GA5153V, with Malaysk rom.

Once my parking sensors are activated, picture of car is showed on left side of display:

Its showing output "only" from 8 sensors, but I have also side sensors on my car installed (12 in overall), I believe that its function of MCU ( I'm not sure about that ) and my question is if its somehow possible to active additional 4 sensors on these android devices.

I know that on original device its working fine, so I guess that CAN-BUS communication should be in place already.
[MTCB Android Head Units General] typos1:
Please read the wiki, there is no such thing as an "Eonon GA5153V", Eonon are a seller not a manufacturer, to find out what unit you have check you settings/about device screen.

Try changing the CAN Bus type in factory settings.
[MTCB Android Head Units General] Vrchnak:
Hello, in that case my device is manufactured by KLD2 running with dual-core CPU RK3066, I already updated my MCU software to last version 2.81.

Do you know if MCU is really responsible for showing this car?

Of course I can try to change CAN-BUS type in factory setting, but do you know if its even possible to show these additional sensors?
[MTCB Android Head Units General] typos1:
Right, you have a Klyde version (KLD = Klyde).

Yes and whatever app appears when set to your car's CAN Bus type (different apps appear for different cars), check out the original thread or other threads about this subject in the forums.
[MTCB Android Head Units General] Vrchnak:
I asked Eonon,

if its possible somehow activate it, I get an answer that they do not support 12 sensors at all, so I'm not sure if it make sense to do something with CAN-BUS settings.
[MTCB Android Head Units General] typos1:
Lol, why would you ask Eonon ? They know nothing, they are not a factory, just a seller, it is possible, search the original thread or look in the MTCB hardware mod forum.
[MTCB Android Head Units General] Vrchnak:
I was thinking that they have connection directly to Manufacturer and they can ask him, most probably they don't.

Anyway I tried to search for in in forum, I checked all topics in original thread and also in MCU hardware forum, but unfortunatelly I didn't find nothing related to parking sensors.

Yesterday I tried to change CAN-BUS in to all VW types there, but any of them doesn't contain support for my car or for 12 sensors.

Maybe last think what I can try is to test all CAN-BUS models which are there, one by one and will see.
[MTCB Android Head Units General] typos1:
Yes and if you dont find any you will just have to wait and hope that support for your car is added in the future.
[MTCB Android Head Units General] losdamianos:
Hello,

My unit Klyde Eonon GA5151 RK3066 / 800x480

I think I bricked my radio as sincu MCU update 2.85 radio keeps loosing its frequency after 2-5 minutes, I have played around with different radio drivers in factory

defaults, I heard that flashing back to MCU 2.3 helps

Oh, I also lost RDS functionality in radio app!

Can anyone point me to earlier than 2.55 MCU please ?
[MTCB Android Head Units General] pa.ko:
Thank you for hint, but it doesnt work.

I installed v1.77 MCU from 4pda.ru (these guys have done great work on organizing content and they have ALL MCUs for downloaded).

With that version - button lights' work as expexted.

Then I reflashed 2.80 - and they are always ON.

So, it is bug in latter version...

I wonder that noone cares nor is fixing such obviouse bug for more than year and dozen of released version....

Of course, there is no point contacting Chinese seller. But I wonder if anyobe here knows the producers, have contacting with developers... I wonder if these guys even have one test unit for themselvs (the reduction of manufacturing costs) :cool:

Anyhiw, as we concluded tge bug, how we can fix it?

Anyobe here is capable of reverse engineering the MCU and fixing this? I am NOT capable of that, but I'm rising this issue as it is not only one but one realy noticable bug with these MCU firmware.

I noticed that from released to released many new and strange bugs are arrising, demonstrating very poor (if any) QA and development methodology of 'producers'. Thus, if we dont find alternative devs for MCUs (as we have God blessing with Malaysk for system ROM!) we will be stuck with gambling of bugs and issyes with every new MCU released. A even the great effort with ROM development, XPosed and other great stuff will be hurt with unreluable and unpredictable MCU functionalities.

Does somebody got an Erisin Unit?

My Unit came up with KGL. I tried all KGL, at least only the KGL 5 works for my BMW Erisin unit. But the Buttons aren't originally mapped and I'm missing my reverse button.

For sure I can remap them with car service, but two buttons habe the same action with the KGL 5 and there is no command for the revers function.

MCU at the moment

[IMG="klyde hu"]https://i.imgur.com/jHPLqb6.jpg[/IMG]

Malaysk Rom

this MCU -> KLD6 2.91 doesnt give any signal will have to come back to 2.85 KLD

I think I have too many variables at the moment, Image and MCU, will go back to one of the original images which EONON has sent me in the past with their old MCU and I'll go from there

hopefully 4.2 should install OK over malaysk 4.4 ROM
[MTCB Android Head Units General] typos1:
No, there are some numbered MCUs "KLD6 v2.91" for instance and some non numbered "KLD v2.85" for instance.

Forget about the image, that is not relevant.

I had a non numbered MCU and installed MTCB KLD6 and everything worked, I then went to MTCC KLD6 and everything worked, but others have had non numbered MCUs and non numbered MCUs do not work.

Just go back to a non numbered MCU, but check all tuner types in factory settings and that RDS and radio area are correct before you do.
[MTCB Android Head Units General] losdamianos:
ahh, RDS in other tab in factory settings, completely forgot and had it unchecked

You have pointed me in the right direction we'll have to play around with MCU's

I have non numbered KLD just generic one (I think)

How am I supposed to flash the image? I must be doing something wrong. I have a Joying unit with the JY MCU.

[MTCB Android Head Units General] Oldpapa49:
Most of the time you need to go into the factory settings and reset your options to what it was originally.

You should of recorded your settings before you updated the MCU, but you can do trial and error.

Maybe someone has a like radio and can let you know the settings.

But I upgraded my KLD6 MCU from V2.81 to V2.91 and needed to change radio to my country and options that I had recorded before I the upgrade.

I'm working fine.

[MTCB Android Head Units General] miffymiffy:
So, I have. Kld2 and I flashed the kld6.2.97. all worked fine and booted up properly. I changed some setting in factory settings including canbus to No. I clicked apply but didn't restat and then clicked on mtc volume. The unit went black screen and then I was unable to see anything even in recovery. I flashed mcu back to kld2 and its working again. I'm wondering if it's an issue with mcu or a change I made? Mtc volume is what caused my unit to blackout, not sure if it was placebo?
[MTCB Android Head Units General] psxsnake:
you should flash KLD2 version not KLD6 (as you could read in OP)
[MTCB Android Head Units General] miffymiffy:
Yeah, I read it. Just wanted to try it to see if it worked. It did. But not certain if the mcu caused the issues or something else. I was primarily wondering if changing the canbus to No or something in mtc volume may have caused it. It was running fine with the mcu for over 20 mins.
[MTCB Android Head Units General] nFKT:
If it went black how did you reflash?

[MTCB Android Head Units General] typos1:
Try the MTCC KLD5 v.297 if you have KLD2, theres no guarantee it will work but its worth a try.

No, this is incorrect, you can flash different numbered versions - I went from KLD no numbered MTCB MCU to MTCB KLD6 then from MTCB KLD6 to MTCC KLD6, but it doesnt work for all units and there does not appear to be any reason why some units work and some do not.
