Hi, I LOVE this ROM wow what a difference it made. I only ran across a few issues which I'm really not worried about I always seem to find alternatives, but I will list them in case someone else had the same problem or has a solution.

My Unit:

Joying JY-UQ130

MCU - MTCB-JY-V2.73

Build - rk3188

ROM - update_4_4_4_FUSE_1024X600_RK3188_13_MAL_10_01_2016

1. Radio sound still sucks! sounds flat, But I have a felling its hardware now.

2. Can't install Amazon app on this ROM the original ROM it installed fine.

3. Sygic doesn't work on this ROM. Just shows black screen. says it download map but every time I restart it says I need to download map.

4. Here Maps works, but Settings Screen is all White. Read it has to do with Landscape mode.

Still trying to find a good Navigation App. Kind of liked Navigon. Any Suggestions? I like 3D maps and need offline.

Questions:

What does the GPS SD card do? What format is it in?

I install 64 GB sd card into slot 2 what can I use it for?

Where do the apps move too? Which SD Card?

Can anyone confirm that these units work with other mics? I plugged in my Kenwood Mic but people can't hear me at all.

Also, my car has 3 wires for the swc, swc1 swc2 and swg (I think for the ground). The radio harness only has 2 wires, will the buttons work if I only connect 1 and 2?
[MTCB Software Development] m4f1050:
Only 1

---------- Post added at 07:15 PM ---------- Previous post was at 07:14 PM ----------

Mine had all 3

My RX8 only uses swc1 and swg. The F150 uses swc1, swc2 and swg.

Please Help!

I think I bricked my Joying JY-UQ124 RK3188 1.6GHz Cortex A9 Quad Core, Resolution 1024*600 trying to install the Malaysk ROM. I was (or thought I was) following these instructions: http://xdaforums.com/showpost.php?p=64147834&postcount=217

I only did step one and now when I hold in the reset button the unit shuts off but never restarts. I must've hit install Malaysk over factory without it wiping or something by mistake. It's all I can think of. I now get the Malaysk kit 4.4 logo and then it starts to load and never gets anywhere no matter how long I wait and as I said holding the reset button in doesn't allow it to start up in recovery.

Please help my dumb ass save my machine!
[MTCB Software Development] doctorman:
keep trying to get into recovery

hold the reset for a long time try combination stuff...

then wipe and resinstall it
[MTCB Software Development] m4f1050:
He's right. Press and hold until it turns off, then press, release quickly then press and hold, kind of like backwards of pressing, press to turn on, then a quick release and reapply reset and hold until you see the recovery letters at bottom left.
[MTCB Software Development] newt_dunbarton:
Ok. I've held reset for over a minute with nothing but I will try the reset, short press, long press, combination stuff... thanks for the quick replies....
[MTCB Software Development] m4f1050:
This is how mine works:

1. Press and hold reset for 15 secs.

2. Release.

3. Quick press, quick release then press and hold.

Copilot is good I've been using it for a while now. I could never get sygic to work, here has issues with the settings, and igo needs new maps, but can't update due to pirated software.
[MTCB Software Development] m4f1050:
I use Navigon. It comes with free maps (here is free too)
[MTCB Software Development] newt_dunbarton:
(Un-)Brick Update

So apparently I had Malaysk sort-of installed and instead of the reset button, I tried holding the power button instead. This worked. I'm not sure what combination but I think hold power until it resets, keep holding until you see the button lights flash and it restart again then let go of power. This got me into Factory Recovery and I wiped all data and upon restart I had Malaysk up and running. Maybe that info helps someone in the future...

Trying to load a couple of apps tonight (Sygic, Google Maps) and then I'll play with it tomorrow. Seems snappy, but I am just grateful I didn't kill it. Thanks for the quick replies...
[MTCB Software Development] veliksam:
So how should I connect all 3 swc wires from my car to 2 wires coming from the radio?
[MTCB Software Development] m4f1050:
Did your radio come with instructions? Mine had the wiring diagram, usually swcg can be ground? Check ur wiring instructions.
[MTCB Software Development] joburgslim:
Regards mics, almost all PC and phone mics will be the electret type,and will be able to work across systems. They consume tiny amounts of power and are fed a small offset voltage on their signal lines. Usually 5v but can be all the way down to 1.7v The most likely reason your Kenwood wont work is the plug/jack layout. Correctly wired the mic should have signal on the tip, and ground on the shield of the plug. Problem is even apple and android standards for this vary, and plugs have been introduced with stereo headphones and mic on one cable i.e. four connectors in the jack. My head unit ext. mic jack came with one of these, even though it only wired up one signal and ground. Try a mono to stereo adapter, or a stereo to mono adapter. The best way is to test connectivity with a multimeter, and match signals up.

I just did the steering wheel controls. You MUST have all 3 wires from the car. I can confirm, once you have identified which is ground, the other 2 can be connected either way around and it works fine. If the ground is not connected, and you can ground it anywhere, does not have to be at the head unit, you will get random control results, mine I had 3 working buttons, and 3 dead.
[MTCB Software Development] spx_trader:
I'm wondering the same thing. I can't get mine to work. Currently I have the 1 and 2 conected to the car steering wheel wires and the the ground to other grounds. It doesn't work. It's a Chrysler 300 if anyone knows.

Great rom, I'm new to these Chinese decks only have had it a week so I've been trying to read through the thread before I ask dumb questions. Lol
[MTCB Software Development] doctorman:
yup that is not new.. people freak out easily when they don't get into recovery first try

glad you worked it out.
[MTCB Software Development] m4f1050:
If you dont have swg, try swc1 from the car to scw1 to radio and scw2 from the car to ground? Also you can swap swc1 and swc2. Make sure you document what combinations you have tried.
[MTCB Software Development] joburgslim:
Wifi problems on 10 Jan ROM

Anyone got suggestions. After many installations which have all become unstable I thought I was finally running. But after 2 days of use, now the system has lost connectivity again. It is the problem where wifi disconnects and wont reconnect. Turning it off results in not being able to turn on again. When this happens, USB connectivity is lost as well, so I usually notice MirrorLink down first. In both cases, they may connect for a second or 2, but will then disconnect. Most of the time just no connection at all. Having had this happen about 4 times, and doing wipe re-installs, I thought it was the enabling of features that knocked the system down. I have been trying to activate Xposed features, and assumed that was causing the issues. This last install, which ran the longest, 2 days, I did not install xposed. I have followed Doctormans instructions very carefully each time. I know a wipe and reinstall will fix it, but I am pretty sure it will just die again. Maybe go back to stock, which ran about a week without this issue, and then I flashed Malaysk. I am hoping someone will know what is up, as I really way prefer this ROM.

Oh,and I keep getting multiple instances of Car Service in the notifications panel.

Thanks
[MTCB Software Development] spx_trader:
I'm starting to think I don't have something right in the settings somewhere. I have tried several combinations. Before this unit I was trying to get a nexus 7 to work in the dash and tried a joycon for the steering wheel controls and when I was hooking that up the car started to do some crazy stuff and the check engine light came on and have some can bus code. I scraped the nexus 7 for this. Not sure if I messed something up in that process either. The light did go out right after I stopped messing around
[MTCB Software Development] veliksam:
Ok, I guess I'll try using the Mic that came with the unit and hopefully it'll work.

About the SWC, from what I understood you connected swc1 & swc2 to the 2 swc wires on the radio harness, and you also connected your swg to any ground wire (example harness ground) or point you can find.

So after you grounded the swg wire, all 6 of your buttons were working?

---------- Post added at 12:07 AM ---------- Previous post was at 12:03 AM ----------

Yeah it did but it doesn't mention anything in cases like mine where you have 3 swc wires. It's cool, I'm going to connect the 2 wires and ground the third.
[MTCB Software Development] joburgslim:
Yes, correct at first I just connected the 2 wires up to the new head unit, on mine called KEY1 and KEY2. Only 3 buttons worked. Then I did a little research on my car, and it was clear the 3rd wire is a ground. Connected and all 6 buttons great.
[MTCB Software Development] veliksam:
Danke for the clarification. So what part of Joburg are you from? I've been there many times but usually stay in revonia. I lived in Margate for about a year, it was nice down there.
[MTCB Software Development] mike.s:
How to wire steering wheel controls or microphones has absolutely nothing to do with Malaysk's firmware. It doesn't belong here. Take it elsewhere.
[MTCB Software Development] veliksam:
Hey Mike, mind your business.
[MTCB Software Development] m4f1050:
It is kinda off topic but no need to be rude, a simple "you might get more help in the Help/Question/FAQ section" would be more polite, and "mind your business" is also not a polite answer to the comment. It's like throwing more wood in the fire... I'm just saying... Let's all get along, glad everybody worked out the switch control issue. As for messing with something and having issues afterwards, I would suggest to take the car to the stealership (dealership) and have them reflash it, maybe you're lucky and it has a fw upgrade? I've never had any swc control change any settings before though... I know that on my VW cc I have all buttons on the left work properly (6 total - up, down, left, right, phone and voice) but on my F15 most of them work (5 total - vol+, vol-, rew, fwd, media) out of 8 work, because of SYNC, the last bottom 3 don't work.

BTW, veliksam, I noticed you are from Orlando (I am too) are you having issues with the 24-hour not staying off? Or do you have 24-hour on because you are used to it or what? All my units (3 total) the 24-hour turns on by itself half the times when I turn on the car, and I'm used to non 24-hour... This happens on this ROM and I believe even on the stock one.

[MENTION=3590033]Malaysk[/MENTION] is there a way to become tomtom work again?

[MTCB Software Development] newt_dunbarton:

[MTCB Software Development] andi1203:
Has nobody an idea to fix the playstore tomtom?
[MTCB Software Development] mike.s:
My business here is with regard to "Malaysk ROMs for any yet known MTCB-Device." Discussion of steering wheel controls and other hardware concerns is not the business of this thread. You'd do well to take your own advice, and take your off-topic business somewhere else, instead of clogging this thread with cruft unrelated to its business.
[MTCB Software Development] FordFocus2007:
Did you also configure the buttons in settings/steering wheel ? As it should work as you set it up

After some tests and trying different versions its working for me now. Had to change to copilot but couldn't wait to have sygic back, as it is the best for me. After uninstalling the latest version, i downloaded the 15.6.6 beta happy holidays version and its now working like a charm.

On the other hand, now my google voice is not working, every time i press the mic icon just says there was a problem and doesnt work. Any ideas?
[MTCB Software Development] grahamwright1:
With the current MTC firmware only the DVD app can send video to the rear monitors. A Java developer would need to look at the decompiled listing from the MTCDVD\Misc\JavaSc\com\microntek\dvd folder to see if they can understand what the calls are that the DVD app makes to output it's video. Since it outputs to both the head unit display and the rear video out ports, there might be something in the code that shows how video can be sent to the rear ports. If there is code there to control the output ports it may be possible to include that same code in app's running directly in the OS.

Of course, it could also be a hardware limitation where the DVD connection goes directly to the MTC where the rear ports are connected, and video can only be switched from the DVD connection......
[MTCB Software Development] newt_dunbarton:
my head unit doesn't even have a DVD player in it. The video outs act as a video passthrough - whatever is plugged into video in can then be displayed on video out (both 1 & 2). That being said, the internal media player can play a video file and I hear the sound on the external monitors but no video comes through. So it seems the audio outs are available to the apps but the video outs are not. I would assume if an app can audio out then it could video out but I have not looked inside my unit to see. I'll email the manufacturer (Joying) and ask them if it is a hardware limitation...
[MTCB Software Development] veliksam:
I am used to 24 hour time format but I prefer to use the 12 hour format, so yes it fits go back to 24 hour just like yours. Hopefully there will be a fix soon.

With the help of my new friend from Joburg I have successfully connected my swc wires and every button now works just fine. I also connected the Mic that came with the hu and now people can hear me.

Is it possible to have dual button functions on this ROM? I see there are 2 little lines under each button when programming but when I try long press it doesn't program the second function. Is this a ROM bug or is dual function buttons not possible in general with these units?
[MTCB Software Development] grahamwright1:
And my same comment around the video-in port stands - if video-in is directly attached and controlled by the MCU then it MAY only be that the MTC/MCU attached connections can be sent to the video-out port. I asked Rambo @ CarJoying about this last year and he did not have an answer for me.

Most likely one of the Russian developers that are familiar with the MCU in this unit will need to take a look at the diss-assembled sources to see if they can identify the function call made by the DVD and AVIN app's to control video output.
[MTCB Software Development] nicolapit:
are they working on this project?
[MTCB Software Development] m4f1050:
Yeah me too. I am already working on an app that will check status of 24-hour and set it to OFF if ON, maybe I can share it with Malaysk after I finish to include in xposed module.
[MTCB Software Development] grahamwright1:
No idea, as I can't read Russian :)

I did take a look at the sources for AVIN and DVD sources and it looks like the 'am' function is the one that controls access to the MCU and video:

From DVD:

if (am.getParameters("sta_mcu_version=").startsWith("MTCB-RM1-"))
imageview.setVisibility(0);
else
imageview.setVisibility(8);

From AVIN:

protected void captureOff()
{
mImageBlack.setVisibility(0);
am.setParameters("ctl_capture_off=line");
}

protected void captureOn()
{
am.setParameters("ctl_capture_on=line");
mImageBlack.setVisibility(4);
}

I'd bet money that the 'am' function can be used to toggle video output to the remote ports.....
[MTCB Software Development] m4f1050:
Interesting... Wonder if it will work with other apps like EASYCAP VIEWER?

I have a ROKU 2 XS hooked up to an EasyCAP and on one of the USB ports, the app turns on automatically when I plug in the EasyCAP

Saving the AV-IN for an Audiovox BluRay player like I have in my VW... Nobody uses DVDs anymore do they? I know I don't... LOL

EDIT: Just found out I get no sound out of EasyCap. I guess I will buy an A/V switch and use AV-IN.. Oh well.

Wifi and USB

[MENTION=3590033]Malaysk[/MENTION]

Some feedback on all my instability issues. On fresh installation everything works great. I use mirrorlink extensively. After a short while, sometimes 20 minutes, sometimes 6 hours of run time, something breaks. At this point if a phone is connected by USB, it will not communicate, AND wifi is disabled in a weird and inconsistent way. Disconnect the USB cable, and wifi starts to work fine again. So USB data connections are interfering with the wifi system. Once I am in this state, I have not found anything that will correct it besides a factory reset and set up from scratch.

I am on Joying v2.73 MCU, your Jan 10 ROM, and very little else as I am frustrated constantly setting things up. I have tried Easy connected 1.3 and 1.4, and I think 1.4 lasts longer, but not sure. It may also be something on the phone that changes? Really not sure. Any help would be appreciated.

[MTCB Software Development] p_mike83:
I tried your suggestion but I cannot get it work. I installed headunit app from petrews, I activated the service and The bt- call switch in its settings. I tried all the BT api settings. I downloaded the recommended contacts ( true contacts) and synced with my Google account.

Google now recognise the frase "call (name)" and tries to place the call, but shows an error saying mobile network isn't available.

However, If I choose a contact within the true contacts app Iit succeeds making the call! (On the first time I .was given the option to select an app to complete action ( there where only 2 possibilities, head unit or TiBu) I chose head unit).

Could you share with us:

1. Which ROM and version are you running

2. Which device (MCU)do you have

3. With " Google voice actions "do you mean Google now? Did you change the Google now app or you used the one that was installed with the ROM? Which version?

4. I supposed you don't use the xposed modules : " xposed Google search now api" and "xposed OK Google for 3rd party" ?

5. Do you have xposed framework installed, and if yes which modules are activated on your device?

6? You said you have downloaded a dialer app from withing head unit app, but in fact true contacts does not contain a dialer (read the description in Google play) did you mind the true contacts app, or did you download any dialer app as well? Which version of the true contact app you use?

7. Which head unit app version use use, and what options you have activated in it?

8. Which phone success to make the call?

I would like to thank you in advance:)

BTW I found out that that if you chose a contact from true contacts app, its makes the call regardless if the contacts are synced with the phone or not.

P.s. I have an eonon unit and the quality of the mic is very good ( at least I did not had any complaints and Google now recognises me, although I am not using my native language.

I have the same issue, I reloaded stock to see if the issue would go away.. same problem Wifi inexplicably stops working, I will say if I am connected to my home WiFi or my phone hotspot never disconnects or stops working so I surmise there is an issue just using the TMO ZTE Hotspot. I will capture some log files and share in this forum maybe we can uncover the issue.

Well after more testing seems the issue is not software, or Hardware causing the intermittent WiFi connectivity I am able to connect to any WiFi without issue, I suspect my TMO ZTE hot spot. Made changes in setup to the HotSpot will test tomorrow and see what happens.
