Well, then you missed it which is pretty odd as he wrote it in big bold letters right at the top. Granted his English isn't perfect (he is Russian) but there are posts from other people after the one I linked below expressing gratitude for him integrating the framework into the ROM.

Noobie to Android

I am a noobie to Android, I bought my first Android phone 6 months ago and now I have bought a Joying Jeep Specific 5.1 MTCD HU. I would really like to install Malaysk on it, but there are a couple of things in the instructions I am not sure of. First how do I get into recovery mode? Second by go back and start flashing again, does that mean repeat step one? Finally, how do I wipe data from recovery?

If there are more detailed instructions on another thread, I would be happy to go there for the answers.

Thanks:cowboy:
[MTCD Software Development] Flockrock:
Is the autostart-app still russian on v5 and v6?

Does someone have a translated version?
[MTCD Software Development] Sventastic:
Hi drinkup4,

it depends on the HU how to get into recovery.

I would suggest you start with the Wiki about the HU:

http://xdaforums.com/wiki/Hui_Fei_Type

if the mentioned ways into Recovery do not work out try this one:

When the HU is running push power button and hold it.

The HU will shut down.

keep holding the button after shut down for about 10 seconds.

Release the Power button and push it again like you want to switch the HU on.

---

Yes.

On first flashing you have to go back into recovery and just do the same step again.

the flashing should look different now.

There is a selectable option in recovery menu, to wipe data and erase cache.

[MTCD Software Development] drinkup4:
Thanks, for the answer. Now that I downloaded the ROM I saw the word document with better instructions than were on the web page. I will try your suggestion to get into recovery.

I would like to do an image backup before I make the attempt and also a separate backup of my apps and back both of those to my SD card. Any suggestions on an app to do that with?

I installed V6, the ROM is nice enough but the problems Im experiencing are massively disappointing. Ive used it now for a couple of days, 14 hours per day solid driving with no improvement in the issues Im seeing.

Lag : the unit is horrendously laggy, same problem as V5 - I had Malaysk with 4.4.4 on what is the same hardware from Eonon more or less and it was fine. Is Android 5 too much for the CPU???? The stock rom seemed fine.

GPS, its still terrible, positional accuracy is horrific and unusable at times. Not sure if its this or another reason but sygic is also laggy as hell and the positional delay can be 10 - 20 seconds behind current position. My gps antenna is in the same position as the 4.4.4 unit used and it was fine then. And no, another nav app isnt a possibility for my needs before anyone suggests, and anyway, similar issues happen in Google mps/nav.
[MTCD Software Development] CadillacMike:
If you have the Jeep joying you don't really need to backup. Joying posts their ROM on their blog. Worst case scenario you have to reinstall your apps.

For the Jeep unit to get into recovery is pretty easy once you figure it out. Push the volume knob in and hold it. Screen will go black and after a bit the button lights will flash. Let go of the knob, wait about 2 seconds and push in (and release) the knob again and it should go to Recovery. A little tricky until you figure out the timing,then it is simple
[MTCD Software Development] drinkup4:
Have you had any problem with lagging like mindriot's comment above?

To date after the first two minutes of start up on the stock rom I haven't had any lag at all. I would like the extra functionality from Malaysk, but I do not want to give up to much performance.
[MTCD Software Development] -=Jeff=-:
Yeah I found it. not sure how I missed... I also found the app on the radio.. All is good, I need to install the radio in the car, right now I am running it on a bench supply (I still have a NU3001, that keeps cutting out installed). the unit is in my fun car so I am waiting until I store it to swap.
[MTCD Software Development] hexer-schwarz:
How did you change the serial number?

If i try to activate any xposed module and restarting the unit it will end in a bootloop. it boots till homescreen and after 1 Second it reboots again and again and again...

where can i change the id?

thank you.

See process , once you set serial up to 12 digit you need to launch GO. It will start downloading. No need to reboot.

[MTCD Software Development] hexer-schwarz:
Ok, the problem was that I didn't install mtcservice.apk from oem folder.

After I installed it I was able to enter a serial number, but it didn't work. the id won't change and TomTom go gives me the known error.

when I try other id changer based on xposed I get bootloops.

another device id changer from playstore just need root. I tried it. but it says that it couldn't write the new id because of write permission issues.

Very frustrating. the id just won't change no matter what I do. ?

Try to reflash again and be sure of a factory setting restore before install any apk. You need to verify if FS isn't corrupted.

not really, but I'm on v4, not v6. However lag is kind of a personal perspective sort of thing. What you define as lag may not count as lag for me, etc.
[MTCD Software Development] trap63:
Install updates from GooglePlay before processing these mentioned steps:

#1 -try to install market helper (posted from me before replying to Malaysk) and transform your unit in phone or tablet i.g. Nexus 7 and replay. Let allow to "google device" to acknowledge modifications before running MTC again (some minutes)

#2 -Please change one digit (random) in proposed 12's from MTC-Service (no need to re-write a new 12 digit serial), without reboot.

#3 -run GO.

Obviously Xposed Installer

needs to acquires

MTC module onboard...., check it.
[MTCD Software Development] drinkup4:
Just to let you know, I installed version 6 and it has not been laggy. It is quite a learning curve from factory original and I thought I bricked it once, but I went back into recovery and cleared cached memory again and it has been working fine since.
[MTCD Software Development] hexer-schwarz:
I will give it a try and tell you later what happened.

Thanks.
[MTCD Software Development] nyogtha:
How is version 6 so far with regards to sudden factory resets? I went back from 5 to 4 because the HU after a day or two would reset itself to factory defaults on boot.

thanks Malaysk for v6 Everything's Goes Well Like Before (i mean Random reboots and wipes) but unfortunately i lost control of my right side panel buttons (Mute, Eject, Answer, Decline, FM Band) what i Have to do? this buttons were working on v5 but now i think it's about "KD based":confused:

For the work is responsible key only MCU !!! you installed MCU.img ?

Did you try to enter "Factory Settings" (pass: 126) and select "Key Study"?

There it should be possible to assign the keys to functions.

As far as I know - is a function to adjust the steering wheel controls. he had stopped working the buttons on the unit !

should i flash it?

thanks for reply

ok thanks let me test it
[MTCD Software Development] sailingwhale:
I have the same situation. Key Study in Factory setting is working but can't save them. Come error when try to save.
[MTCD Software Development] CadillacMike:
There is the Wheel Key app for the Steering Wheel Controls. But what they are talking about is in Factory Settings, there is a Panel Key option that let's you remap the physical keys on the head unit.

For example on my Joying i changed the "BAND" button from the Radio app to the app switcher button.
[MTCD Software Development] sailingwhale:
Unit buttons are working only if I restart device from Factory Setting (make apply & exit), otherwise all unit buttons are dead.
[MTCD Software Development] dongali:
Could you give directions on how to do that? Go into factory settings then to key map?
[MTCD Software Development] mindriot:
Hmm, seeing as the amount of useful answers equals the amount of ashtrays on a motorbike I will try again.

The unit is unbearable. Completely unbearable.

Worst when running sygic, and I think its possibly all linked to the GPS. Lollipop apparently suffered horrendous gps problems on various devices. Could this be a reason?

When the gps goes completely loopy, everything freezes up, lag is at its worst, even interrupting streaming playback in spotify, stuttering or completely stopping for minutes sometimes. Sometimes I have to operate the reset button to get it working again.

GPS lag can be 3 - 30 seconds behind, stuck altogether or suddenly inaccurate and drifts off as much as a hundred meters or more, and in random directions, or stuttering the position as it tries to re-establish a better fix. Its never current even when its at its best, always dragging just enough behind to make life a misery in unfamiliar city streets or complex road systems.

Without sygic running spotify is a lot better, but still suffers at random points.

Ive tried clearing the app caches, reinstalling sygic and spotify, no improvement.

If its not GPS could it be an MCU compatability issue?

If neither then what????
[MTCD Software Development] dongali:
Maybe try stock again to see if same problems persist. If not, the it's malaysk rom issue.

Or you could try the newest stock rom that I was able to find for Android 5.1.1 Quad Core MTCD units dated Aug 5, 2016 with latest features/bug fixes:

xtrons.com/firmware_updates/latest-Android-5.1-20160805.rar

All MTCD roms should be interchangeable regardless of MCU. Only flash the dupdate.img and NOT the dmcu.img!
[MTCD Software Development] fx200984:
Hi,

Today I upgraded from v5 to v6.

This rom is really good, all seems to work like a charm.

The only problem I have is that in the previous version (v5) there was an option to let the gps control the brightness.

And in the new version (v6) I can't find it and I don't remember were it was.

Can somebody tell me where to activate this option if it still exist?

Thank you very much.
[MTCD Software Development] ptclabs:
My thoughts on the v6 rom.

I think there is a issue with the mcu and this rom on jy units. The buttons are really laggy (seconds) to respond. The usb keyboard no longer works in recovery (this is an issue I cannot remove this rom)

There seems to be a jy mcu as listed in another thread, the buttons die/double boot issue.

update button crashes. jy svc crashes. I think it is mostly mcu problems. Tried to get a newer mcu on there (1.65 currently) but with no keyboard in recovery and no update button it is really hard to do.
[MTCD Software Development] ikerg:
I think you have to go back to stock rom and there check if everything worked as expected....make the mcu update and then go back to Malaysk.

If you have not access to recovery or any way to control the recovery options....the only way I think is possoble is by connecting the headunit to a computer .

With rktools you can upgrade the ROM (only the ROM....I dont think that with that method you could upgrade the mcu as dmcu.img is not recognized by rockchip tools)

Somebody got his MTCB device alive from.brick with this method

---------- Post added at 06:03 PM ---------- Previous post was at 05:59 PM ----------

Still don't understand why this would affect brightness settings... it's not like there is a built in Lux for it to be dependend on sunrise and sunset times
[MTCD Software Development] gunmoule:
It is just a software automatic brightness adjustment. It uses GPS time and position to determine if it is night or day. If day brightness will be high if night brightness will be low (you may want that because at night the screen will blind you by contrast with the dark outside). Another option available in the rom is to adjust brightness depending on car headlights state.

There is no need for luminosity sensor for that. Drawback is for example during the day you go trough an underground route, tunnel, ect... brightness will remain high because gps tells its day and day is high brightness.

BTW, I just flashed the v6 and MCU 1.82 on my KD unit and it works great.
[MTCD Software Development] res_au:
If from recovery you do install from update on sd/usb etc and the MCU image file is on the root directory of the sd/usb (as well as the rom image). Will the MCU be updated as well? Or do you have to do it a different way? Thanks for your help.
[MTCD Software Development] sterod:
Its hit and miss. Typically I do the dmcu.img first, with that being the only update file in the folder, and when that is done, I take that dmcu.img file out, and put in the dupdate.img file in, with that being the only file in the folder.

[MTCD Software Development] CadillacMike:
what does the Touch Study do? I opened it, and couldn't figure out what it was doing
[MTCD Software Development] mindriot:
Well Well!

I "might" have solved my issue.

When the unit was first flashed, I switched to the JY511 launcher, its what Im used to and I never got beyond it with all my hassle with the previous Eonon rubbish.

In the last few days Ive tried every last thing I can with this Joying, the only noticeable improvement seemed to be when I installed fastgps and localised settings to the UK and uk ntp servers.

Whilst sitting taking a break at a motorway services I took a little time to try to think outside the box, its difficult to do much when you drive 14 or more hours per day.

I never got round to trying carmod launcher with all my past hassle, so I switched.

Suddenly it all started behaving and the lag went, and the touch screen returned to an almost acceptable level of sensetivity (no doubt partly related to performance), and sygic lods quicker and animates smoothly whilst driving , and the gps accuracy improved dramatically.

Ill test for a couple more days but it may all have been down to the JY511 launcher!

Added bonus is carmod launcher picks up spotify for its media player and the home screen controls handle it perfectly, bonus as flipping all the screens was getting tedious, not to mention hazardous with all the lag.

Anyone else experiencing lag with Joying please try and help confirm its not just a fluke on my device.

Now all I need to do is figure out why my mic isnt picking up anything, its plugged in but hears nothing for calls.

Cannot find MTCservice

I've installed V6, but didn't have the time to play with it a lot. Upgrade from V5 went smooth though and in the few minutes I played with it I didn't notice any strange behavior.

One thing I cannot find however, is how I can change the serial in order to execute Tomtom again. I followed the instructions Malaysk gave, trying to start the module from Xposed, but I don't see it as an option on my screen (see picture attached). Also, I cannot download any module with that name. What am I doing wrong?
[MTCD Software Development] Sventastic:
The Touch Study is for recalibrating the touch screen.

if you open it you have to touch some positions as shown on the screen.

Mine was like this:

in the upper left corner in red color 1+

in the lower right corner in white color 2+

first touch 1+

(1 gehts white, 2 becomes red)

second touch 2+

if you do it wrong your touch screen will be messed up.

then you better plug in a USB Keyboard and Mouse and use them to get back to the "touch Study"

I installed V5 on a 2nd Joying 7" MTCD unit that I own. I did a complete wipe and reload via a USB stick using the factory recovery menu (holding down power until lights blink, etc) The unit will work fine for a few reboots, then suddenly for no apparent reason, it will boot loop. The device will show the booting splash screen, finishing booting and show the desktop for about 1 second, then reboot itself and start the process again. When this happens, the only action I can take is to wipe the dalvik/cache and start all over again. I have tried reloading the ROM from scratch, but nothing seems to make a permanent fix.

The only way I stopped the boot looping was switch to a non-Joying launcher right after I flashed v6 and don't use the reboot/power button at the top of the screen. I would load a few apps at a time, then shut down the unit. Works good now, but does have about a 8-9 second lag running Google Maps, otherwise is fine.
[MTCD Software Development] sterod:
With V6, CarMod is the default launcher, which is Non-Joying, and that is the one briefly displayed for 1 second before it reboots itself. Are you referring to the physical power button or are you referring to the software "reboot" icon in the top right corner of the status bar?
[MTCD Software Development] DMITCHELL22:
The boot loop I saw with v6 only happened after several apps were installed, I switched to Joying launcher and used the software reboot icon. Hope that helps!

Yes, this MTCD ROM is compatible with your MTCD unit.

The ROM is pre-rooted.

You install it by putting it on a USB stick or putting it on a MicroSD card and entering the recovery mode on your device using the physical buttons. The sequence to get into recovery is different for each device.

There are also detailed installation instructions contained inside a MS Word document in the Version 6 compressed install package.
