I tried KLD5 and it borked. I went back to 6 and all is good. So KLD2 to KLD6 works as expected. Only issue I have found is SEL button has changed to DVD and DVD is also DVD. Other than that it is all good. With DSA 5.1 image, it works well..

MTCB to MTCC i should add
[MTCB Android Head Units General] typos1:
Yeah someone else said the same about KLD5, it actually came from a single DIN unit with a fold out screen, maybe it only works on similar units ?

MTCC KLD6 v2.97 is out now btw, its on the fileserver.
[MTCB Android Head Units General] nFKT:
KLD5 is also the one that borked my unit. I'll try to flash over to KLD6 tonight and fix this.

What's the best way to get into recovery mode when I can't see the screen at all on a KLD unit.
[MTCB Android Head Units General] miffymiffy:
I just held the power on and pressed my reset button. My unit flashes different colours when in recovery so I just kept playing till it did that. Scroll once down and hold power for a sec to select update without wipe
[MTCB Android Head Units General] nFKT:
Is the screen blank even for recovery or should that show up?

Cheers man! :good:
[MTCB Android Head Units General] miffymiffy:
before yes, after no.

i have JY 1.74_2 ,, can i flash the JY 2.73?
[MTCB Android Head Units General] typos1:
"JY 1.74_2" ? do you have an MTCD unit ? What letters appear before the "JY" ?
[MTCB Android Head Units General] SirOrigami:
mtcd jy-1.74_2
[MTCB Android Head Units General] typos1:
Thought so, you are in the wrong forum, this is for MTCB/C units, you need the MTCD forum.

DO NOT INSTALL AN MTCB/C MCU on your unit !!
[MTCB Android Head Units General] SirOrigami:
THanks man
[MTCB Android Head Units General] Goaz:
typos1 hi mate,

can u please confirm me that MTCC KLD6 2.97 can be installed over a MTCB KLD6 headunit without problems?
[MTCB Android Head Units General] typos1:
Yes, several people including me have done it, you may have to reset factory settings (check what there are currently before updating0, or you can save them as an mcu.cfg file and flash that (as you would the MCU) after youve updated the MCU.
[MTCB Android Head Units General] Goaz:
thanks typos1, how am I supposed to save the mcu.cfg ? is there a guide or a well known procedure?
[MTCB Android Head Units General] typos1:
In factory settings there is a "save" button.
[MTCB Android Head Units General] psxsnake:
you know where will be saved?
[MTCB Android Head Units General] typos1:
No actually, there is a post about it towards the end of the "Interesting ROM with FUSE support" thread.
[MTCB Android Head Units General] pa.ko:
On GPS sd card root
[MTCB Android Head Units General] psxsnake:
I did Export and the mcu.cfg was saved but not on GPS root card... I supposed too

but i cant find it
[MTCB Android Head Units General] pa.ko:
Look other roots (internal sd, external as)

Mine was saved on GPS root.
[MTCB Android Head Units General] Goaz:
and then how do I reinstall that mcu.cfg in case I need to?
[MTCB Android Head Units General] pa.ko:
Fro recovery just as if it is 'firmware' - installmupade or something like that.
[MTCB Android Head Units General] Goaz:
it doesnt work, it says "no mcu update fund, aborted", tried it twice without succes, I've copied the mcu.cfg on sd card and put into gps slot but it's not working at all.

How is it possible to update the mcu.cfg if that's not an update ???

Anyone has ever tried to put back the mcu.cfg?

---------- Post added at 10:20 PM ---------- Previous post was at 10:05 PM ----------

Anyway I also wanted to confirm that I have successfully updated my HU MTCB MCU KLD6 v 2.81 to MTCC KLD6 V 2.97 , the only thing not working is the SEL button which opens the DVD instead of equalizer as it did before, and the DVD button open the DVD app.

Before updating the MCU i export the mcu.cfg on my gps sd card, then updated the MCU then tried to flash also the mcu.cfg but it say no updated found.

Any idea how to fix it?
[MTCB Android Head Units General] typos1:
Did it say anything about mcu.cfg in the yellow writing in recovery when it said MCU update not found ? - Theres usually lots of other text.

Technically its not an update, it should just say loading mcu.cfg or something similar.
[MTCB Android Head Units General] pa.ko:
Exactly.
[MTCB Android Head Units General] lysiong:
I have update the Joying MCU to the latest version yesterday. So far so good.
[MTCB Android Head Units General] Goaz:
fIXED it, updating of mcu.cfg worked ;)

thanks again: D
[MTCB Android Head Units General] typos1:
How dya do it ?
[MTCB Android Head Units General] djgus74:
A silly question but I am new to this and do not want to mess up, if my unit has mcu "ha", you could put mcu "kld" for example?

Regards
[MTCB Android Head Units General] typos1:
No, generally you cant, the only 2 that are interchangeable are BN and HA (as Malaysk says in his first post with the list of MCUs), so you good try an BN one.

The wiki in my signature gives a lot of info about these units.
[MTCB Android Head Units General] Goaz:
I had erronesouly put the wrong sd card into gps slot.., when I realized that just put the correct sd wirh mcu.cfg file and flash it from recovery.

Hello

is it safe JY v.2.86 ? :confused:

I have a MTC-B Joying 4.4.4 :p

Regrads
[MTCB Android Head Units General] Oldpapa49:
As a side note, I asked Pumpkin for my mcu.img for backup since I did repair my canbus decoder.

Told Jammy on Pumpkin it was KLD6-V2.81.

His reply that that no longer use that he will send me an updated mcu image.

This answers that question that mcu.img can be a higher rev level. The question is what will he give me.. Will it be kld6-v2.83 to v2.97

Tomorrow will tell.. I can hardly wait to see.

If its V2.97 then as we know it, it will be MTCC compliant.

If it is a lower rev, then they holding onto MTCB levels which I think is V2.85 or something close and below.

This all speculation.
[MTCB Android Head Units General] typos1:
Lets hope its a later MTCC version than 2.97.

[MTCB Android Head Units General] ultradj83:
Ho everybody.

Any Lollipop ROMs for RK3066?

I'm still with 4.4 from Boorondook with MCU 2.64 from Darkleo.

There's a problem with LEDs that are on just during boot, then always off.

Any ideas?

Thanks everybody!
[MTCB Android Head Units General] typos1:
No L for RK3066 sorry.

Go into factory settings for the LEDs, if hat doesnt help try a different MCU version.
[MTCB Android Head Units General] dhmsjs:
Definitely a DOS command. I have used it often. I thought I read somewhere recently that there is a -v switch for showing the version but I can't seem to make my version (1.0) accept that switch. But the MCU version string is easy enough to find anyway.

1) At a windows command prompt run the command "mtcmcutool -d mcu.img mcu.bin" to decrypt the img file into a 8051 executable binary.

2) with your favorite binary file viewer, search for the string "MTC". That should put you in the general area. You'll see the version string fragments nearby.

3) Alternatively you can use the opensource d52.exe to disassemble the .bin file, and search through that.
[MTCB Android Head Units General] ultradj83:
Well I use this MCU because it's the only one with real standby, pushing left noodle 3 secs shuts amplifier, USB, ecc, but Android is kept on and immediately available pressing the noodle again.

LEDs are a minor problem.

Do you know a MCU can fix LEDs keeping standby?

Tks a lot.
[MTCB Android Head Units General] typos1:
No sorry, your ll just have to try all the available MCUs for your unit.

[MENTION=456516]typos1[/MENTION] I've just noticed the file server has MTCC KLD9 v2.98 and I currently have MTCC-KLD6-V2.97. Can I upgrade or is it worth upgrading? How come KLD6 is now KLD9? I'm presuming I newer model of Klyde system has been found? Have you upgraded to this version?
[MTCB Android Head Units General] typos1:
I didnt upload it !

What makes you think KLD6 has "become" KLD9 ? KLD9 is another KLD numbered variant.

Try it and see if it works. I know KLD5 didnt for most people, but then it was from one of the rare units with fold out screens, so that kinda made sense.

I ll try it myself later. If it doesnt work it may well work on units that have so far not been able to upgrade to MTCC, maybe someone who has a unit that the MTCC upgrade would not work on could try it ? I d suggest [MENTION=6041319]dsa8310[/MENTION], but I dont think hes bothered.

EDIT: Actually I think I did upload it, someone said its for a BMW E90, it was mentioned the Lollipop thread a few weeks back.
[MTCB Android Head Units General] tariqkhan.co.uk:
Sorry, thought you put it there. I've been searching the forum and found DSA mentioned that it is an "E90 dedicated MCU". (E90专用MCU). Not sure what that means, but the use of the word dedicated implies to me that it is for a specific version of hardware maybe so unlikely to work? Might give it a try.
[MTCB Android Head Units General] typos1:
Yeah, I did put it there, see my edit !

"E90" is the BMW internal codename for the 2005 3 series, so its for the built in units specifically for that car, there were a lot of users that could not get the keylights working properly on E90s, so I m guesing it has some special function that works with the E90's CAN Bus system. Try it though, cant do any harm.

Mtcb-kld6-v2.86

Hi guys does anyone have a link to download this mcu

MTCB-KLD6-V2.86

radio stopped working when new mcu went it so would like to go back to this mcu file

thank you in advance
[MTCB Android Head Units General] typos1:
Its on the fileserver in my signature.
[MTCB Android Head Units General] gringo76m:
I can only see the 2.85 ver not the 2.86?

Hi typos thank you for your reply ive been on the file server but when you go in firmware then mcu then kld it dosent have 2.86 just has 2.85

then the mtccs after that am i looking in the wrong place ?

thanks in advance
[MTCB Android Head Units General] typos1:
Actually we dont actually appear to have a copy, but 2.85 should be fine, but if you can use 2.85 you will be able to upgrade to an MTCC MCU, which is on 2.97 currently.
[MTCB Android Head Units General] gringo76m:
2.85

currently running 2.85 but still get no radio no matter what i change it to in factory settings ill give the mtcc 2.97 a try and see how i get on thank you for your help
[MTCB Android Head Units General] Spikee:
Here is a copy of MTCB-KLD6-V2.86. (thx to [MENTION=5797001]macca017[/MENTION] )

https://mega.nz/#!FwpwARAa!W966JLtWiwrUen7aAbqq0Goo-7uGWBP_G3Qv2MbhMWU

But i think the Problem is not the version you have installed. Have you made the right tuner settings in Factory Settings? When you make a upgrade/downgrade of your

mcu these settings are changing and you have to set them manually or from a settings backup.

my tuner is TEF6686. maybe you can try this.

Hope it helps

Spikee

edit---------------------------------------------------------------

Sorry have read it to late. So try the 2.86 then
[MTCB Android Head Units General] typos1:
MTCC v2.97 is the best version to use if you had a late MTCB MCU. Check all factory settings before install and make sure they are the same after installation as [MENTION=228182]Spikee[/MENTION] says.

I ll upload MTCB v2.86 to the fileserver.

Which one is the best firmware he can install? Only KLD5 (2.77 is older than he has) or can he install a newer KLD6?

Can anyone send me links to latest update.img and mcu.img?

Pay attention to the screen resolution (800x480)

Thankyou in advance.
[MTCB Android Head Units General] typos1:
You are getting MCUs and ROMs confused, you can update to MTCC KLD5 v2.97, you cant update to KLD6 MCUs. The screen resolution has nothing to do with the MCU. v2.97 is in the firmware section on the fileserver in my signature.

For the ROM (Android part) you can use ANY quadcore (RK3188) ROM with 800x480 resolution. Look in the software section, theres booroondook's ROM ("Interesting ROM with FUSE support" thread) Malaysk's 5.1.1 ROM or DSA8310's 5.1.1 ROM (in the "Lollipop for MTCB/C Headunits" thread.
[MTCB Android Head Units General] Wolf Hamburg:
You do'nt need to update the mcu.img. You can update the update.img only.
[MTCB Android Head Units General] typos1:
He doesnt need to update the image either. But why would he not want to update his MCU to the latest version ? !
[MTCB Android Head Units General] javierreg:
hi , you update your td101a to 5.1?

work fine ?

where firware you use ?
[MTCB Android Head Units General] Wolf Hamburg:
Of course he can when he want this. But the newest isn't always the best. When his Rom which he has updated works fine with his MCU he has no reason to change.

Or what is better on the newest MCU? Any new Features?

But how i wrote... Of course he can.
[MTCB Android Head Units General] typos1:
With MCUs newer is generally better, if there are problems then he can downgrade, there are no reported problems with KLD5 v2.97 on units that have KLD5 MCUs from the factory.
[MTCB Android Head Units General] Wolf Hamburg:
Ok, ok, I just wanted to say that it is not absolutely necessary to update the MCU.
[MTCB Android Head Units General] typos1:
Yes I know and I just wanted to say IT IS BEST PRACTISE TO UPDATE THE MCU WHEN A NEW ONE BECOMES AVAILABLE .
[MTCB Android Head Units General] Wolf Hamburg:

I hate to be the noob in the room, but about 6 months ago i updated my eonon ga2114 to the malaysk 4.4.4 rom. i also updated the mcu while i was at it. So from what i've been reading, is it possible for me to load an mtcc kld6 v2.97 mcu from my current mtcb v2.84, onto my unit as well as the 5.1.1 rom? If so, i already have the rom, where do i find said mcu image? i did a lot of searching. Thanks in advance for any answers guys.
[MTCB Android Head Units General] Wolf Hamburg:
Unfortunately the server in typos1 signature is currently down. Wait til it runs or ask typos1. Maybe he can send you your MCU
[MTCB Android Head Units General] typos1:
PM me your email and I ll send it to you.

You dont have an "EononGA2114", you have a Klyde MTCB/C unit, Eonon are simply re-sellers.

Hey. I have a radio company XTRONS TD 626a with the following parameters

Anddroid version 4.4.4_24122014

build number rk3066-eng4.4.4.24122014

version MCU MTCB-GS-v2.08

Please let me know if I can do MCU update.

Can I change the default music player to operate the buttons.

Current program not have the option to choose music files randomly.

I do not have much knowledge, but I have read that installing the wrong MCU can damage the radio.

[MTCB Android Head Units General] typos1:
You can update to a GS MCU, updating will not damage it, you need Xposed MTC app to remap buttons.

Alright, I updated my 4.4.4 kitkat to Lollipop. Without issues honestly, however i also updated to the kld6 v2.97 mcu from v2.85 and have a wonky volume button now. Is there anyway to downgrade back to 2.85? You guys have been great by the way. Cheers!

p.s. Lollipop is so much nicer! Wow is all i can say there.
[MTCB Android Head Units General] stepien:
Thank you for exact instructions ;)

And is it possible to upgrade to android 5.0 or 5.1?

The manufacturer claims that it did not, but their support is very bad.

Which versions Xpoxed install? It may be a version 1.4.2.
[MTCB Android Head Units General] Wolf Hamburg:
Hmm...

If this is so, and I do not doubt, then the version of the Fileserver (KLD9 V2.98) is certainly a write error and should be called KLD6 V2.98

My original MCU is a KLD6 V2.91 and I inadvertently flashed the KLD9 V2.98. Everything works fine.

Even if I press the reset button, the radio does not forget its stored frequencies. This is unfortunately not the case with the KLD6 V2.97 and the transmitters must be saved again.

Therefore, I think that it is perhaps a write error and KLD6 V2.98 is to be called. If this is the case, maybe someone should correct it. Or maybe I'm just lucky that this KLD9 V2.98 on my radio works?

Edit: Ha ha .. me just came to mind, I could look at the head unit what the version info says :D

There is also KLD9 V2.98. But as I said, it works best on my KLD6 :confused:
[MTCB Android Head Units General] typos1:
What do you mean "wonky" if you mean it goes up and down it is probably in "freewheel" mode which can be disable in factory settings. Did you check factory settings before upgrade and make sure everything was set correctly after the upgrade ?

So are you saying that the KLD9 is shown as KLD6 in settings/about device ?

I have not checked KLD9 v2.98 - I was told it was for BMW E90 vehicles.
[MTCB Android Head Units General] Wolf Hamburg:
No, there is KLD9 V2.98. I'm just confused because I assumed that I can only take KLD6 if my original KLD6 is. By the way, I have an old VW Passat 2003 without steering wheel control
[MTCB Android Head Units General] typos1:
Ah, see, it doesnt always work that you have to update the MCU to one exactly the same as yours - several people have upgraded from KLD (no number) MCUs to KLD6, including me, its useful to know that KLD9 works and saves stations.
[MTCB Android Head Units General] Wolf Hamburg:
Yes, I have previously pressed again the reset and my stations were all still there after the booting :)
[MTCB Android Head Units General] Johny DJ:
I also have KLD6 2.97 and if I just enter the recovery from long press volume button, the stations are reset, but if I enter the recovery from system itself (recovery mode from reboot option) the stations are not reset.

So you said that if you manualy force long press recovery the stations are not reset, what about flasing new rom or wipe data?
[MTCB Android Head Units General] Oldpapa49:
That sure sounds interesting. I can download it via my unit and put it on a USB since I'm on vacation and about 600 plus miles from my laptop
[MTCB Android Head Units General] Wolf Hamburg:
If I press with the KLD6 2.97 the reset button are the stations after the boot away.

If I press with the KLD9 2.98 the reset button are the stations after the boot still there.

From recovery I don't know, I haven't tried.

ROM I did not flashed, only MCU
