Hi malaysk;

Is it possible you post the roms somewhere else? It takes 9+ hours to download here in the USA.

Hi all,

I have a strange problem with my unit.

I have a rk3188 JY 1024x600 unit with the latest rom from [MENTION=3590033]Malaysk[/MENTION] (13-08)

Attached to this unit I have a usb2.0 camera.

When I start the Car Record app, run it for 3 minutes,

I get a message: Usb device disconnected

and the video is gone.

I have to reboot to get my usb cam working again.

I search the forum, but the only thing I found is the lake of power on the usb port,

could this be the cause of the problem and do I need a powered usb hub to make it work

or is there some kind of power saving active in the rom for the usb port.

I searched all settings but couldn't find one

or maybe I missed it.

I hope someone can help me with this issue.

Regards

Mauro

Edit1: Little update for today:

I did a factory reset, reverted to the original rom, again factory reset

and updated back to the Malaysk rom.

Gonna test it tomorrow.

Let you now if it fixed my problem

Edit2: Tested the unit today and everything working now.

I think I messed up the rom with installing RTL2832U DAB USB stick.

Or the drivers for RTL2832U are not correct or the host check fix did something wrong.

In my region the reception for DAB was very bad so I remove the RTL2832u again,

so after a complete reinstall and not installing RTL2832U my problem is solved.

Carjoying Head Unit - Not responding to ROM upgrade

Hi All

Has anybody managed to install the Malaysk ROM on one of these units carjoying.com/eu-warehouse/double-din-android-stereo/joying-europe-eu-warehouse-2015-latest-aftermarket-7-inch-2-double-din-1024-600-in-dash-car-stereo-android-4-4-4-kitkat-quad-core-head-unit-autoradio-16-gb-memory-touch-screen-airplay-gps-navigation-ra.html The unit updates automatically when you insert the update sd card in the GPS slot but nothing is happening for me, I have previously upgraded the unit so I know the process works but there must be something missing with this ROM.

Any help would be greatly appreciated.

Regards
[MTCB Android Head Units Q&A] koimr:
This has happened to a few people (including myself).

Just boot into recovery and do the update from there.

Instructions for getting into recovery are on the first page - if they don't work for you (might be outdated), you can root your current ROM if it's not already rooted and install a "reboot to recovery" app off the Play Store.
[MTCB Android Head Units Q&A] dadd10:
Many thanks Koimr, I'll give that a go, if i come across a solution to the auto upgrade I'll make sure that I post it here, it's a great way of upgrading if you can get the rom recognised.

Regards
[MTCB Android Head Units Q&A] Twilek:
To get the carjoying radio to offer you an update, you have to have the update.img AND the mcu.img on the SD Card even if the MCU image was not updated (simply add the latest MCU image to the latest Malaysk image and you should be fine).

Ah and by the way if anyone knows a way to control the recovery mode with an "touchscreen only" (no hardware buttons at all, only touchscreen buttons which don´t respond in recovery) radio by carjoying please let me know.
[MTCB Android Head Units Q&A] killabee1980:
Also happend to me, I solved it to put the update.img onto a usbdrive and run the update from usb instead of sdcard(gps)
[MTCB Android Head Units Q&A] agentdr8:
You can try a usb mouse or keyboard.
[MTCB Android Head Units Q&A] sunripe:
I'm having the same message in a RK 3066 1024x600 with latest Malaysk. No idea what is this.
[MTCB Android Head Units Q&A] dadd10:
Hi Twilek, that is exactly what I did and purposely used the joying supplied MCU image so that I knew it was correct, I wondered if it could be that the MCU image is the latest and is already installed on the unit and so would not initiate the update but you should be able to reflash to cure any issues you may have with the unit.

Regarding the rooting of the unit this comment was posted on the carjoying blog page, is this a valid comment, seems a bit too simple!!

"Actually this is a very out-of-the-way procedure to root the device. For root, go to Settings->Factory Settings and when prompted for the password enter: *#hct#root# This will temporarily give you root, to make it permanent install either SuperUser or SuperSU from the Play Store"
[MTCB Android Head Units Q&A] agentdr8:
zomg they ripped off my post! :silly:

But yes, it's accurate, except there's no need to install Superuser or SuperSU; after you enter that password the device is permanently rooted.
[MTCB Android Head Units Q&A] Blaze Falconburger:
Thanks for the reply - I'll pull the unit in the next few days to confirm, but at this time I think it is more of a ROM issue as I didn't have this issue on stock the ROM.

I don't believe the issue at startup - when I used pvcbuilder PA starts and plays immediately, so the storage (USB HDD) is mounted OK. I tried the option to wait for USB to mount but this had no effect either way.

If I don't launch PA automatically and wait for the unit to fully boot and launch it manually - I get the same. If I then gracefully exit PA and reload - it resumes from the correct position in the track. If I then shutdown the unit with the ignition, wait a few hours and start it, it resumes from where it was when I cleanly exited PA before the shutdown.

So at this time I think it's a shutdown issue, but the file playerservice.xml which stores the last track and resume position (in seconds) does not get updated. Maybe PA isn't cleanly exiting. It seems strange that I'm the only person who is suffering from this though..
[MTCB Android Head Units Q&A] warr4768:
Don't think this question been asked before , but as these devices are only 1gb of ram is there an app or can you change the settings so you could use say a 4gb usb stick as virtual ram like you could do in windows. Maybe one for dsa8310/malaysk?
[MTCB Android Head Units Q&A] dadd10:
Hi agentdr8, I cannot understand why there are so many posts requesting info when it is that simple (as long as you know the password I suppose). I have resolved the issue with my unit now. I recently, like yesterday, installed the latest firmware upgrade without backing anything up, so thought I would check whether the unit would recognise the official upgrade again and it didn't! After cussing myself for buggering it up I thought perhaps there was a setting that needed resetting, I looked in the settings and pressed the system upgrade button and low and behold it found the upgrade :) I then put the sd with the custom rom in and to my surprise it recognised it. As you can imagine I am now one happy bunny :) settings galore to alter!! just need to change the radio app at some point.
[MTCB Android Head Units Q&A] koimr:
I've tried it with both update.img and mcu.img on the same SD card with no luck in getting it to prompt to update.

For your unit with no hardware buttons, yikes - I think [MENTION=434511]agentdr8[/MENTION]'s recommendation to use a mouse or keyboard might be your only bet.
[MTCB Android Head Units Q&A] SilverViper2k:
I have some more feedback for Malaysk's rom. Whenever I try to open the MyVideo app, my unit seems to crash. I see the custom boot logo, but doesn't do anything else after that. I need to use the reset button to fully boot again.

And just out of curiosity, there's a screensaver that shows the time after a period of inactivity. I'm wondering which app or setting is responsible for that?
[MTCB Android Head Units Q&A] dadd10:
Hi Koimr, Please see my comment to agentdr8, with the resolution to my problem, the simplest solutions are always the best :)

MCU

Hi all, I currently have the v2.55 of the KGL MCU. I am trying to decide if I should update to the newest one in the repo (v2.68). Does anyone know what differences there are in the way of possible fixes?
[MTCB Android Head Units Q&A] koimr:
I did see that after I posted, I will give it a try next time I update.

To be honest though, I find it nice and easy to just boot into recovery and do it from there.

Just thinking - the latest Malaysk ROMs have recovery options to not delete data (if I read things correctly) - I wonder if that's the default choice when there's an update prompted from outside recovery. Hmm. :)
[MTCB Android Head Units Q&A] vdubskey:
I think it's the way Android handles USB devices as in not keeping the devices assigned to the same location even if the device was plugged into the same USB port. Also your using USB hard drive? Not flash drive? If that's the case, does it have external power? If not I would try what I suggested earlier and hooking up to a powered usb hub. I have a carnetix powered usb hub made for automotives from my carpc days. A little more expensive but extremely reliable and not dependant on the head unit for power. And it has selectable power off times as well to keep the hub powered AFTER the head unit has fully shut down and powered up BEFORE the head unit has reached the OS.
[MTCB Android Head Units Q&A] agentdr8:
MyVideo is a launcher for the preferred video app that's defined in XposedMTC. Set it to some app and it shouldn't crash any longer.

The screensaver is actually the Dream service.

Steering wheel key settings has 'disappeared' from settings menu, any suggestions for restoring please? thanks
[MTCB Android Head Units Q&A] Blaze Falconburger:
For albums, sure - skipping is no issue, but I listen to a lot of podcasts, audiobooks and mixes which are typically 1hr+ long and span over multiple car journeys - it is now getting slightly annoying when it keeps losing the position every single time.

I have performed troubleshooting with the PA author before posting here and he concludes the PA service is not being shut down cleanly, so it does not write the last played position. When the unit then next boots it plays from the last saved time when the track started, ie the beginning, when the track was selected. I have submitted a feature request to have PA update the current playing position every 5/10/15 seconds as a workaround, but not convinced it will get accepted or an ETA for implementation.

I have also found 2 other players that behave in exactly the same way, so it is not isolated to just PA. In fact it worked with PA on the stock ROM, just not with Malaysk - so this is not a hardware issue. I have just sent details to Malaysk to see if he can offer some advice on why PA might not be getting shutdown cleanly - rolling back to stock is an option I guess, but certainly not my preferred, having experienced the wonderful Malaysk ROM.

I was hoping if others are suffering, then hopefully through the power of this forum and collective knowledge we might just get closer to a fix or work around :good:

Solved, I forgot to erase averything after upgrade, now i did and all working OK. Thanks Malaysk for your great job.

Unit blown up

Hi people,

I have not shown up in a long time (big changes require loads of attention). I tried to be up-to-date as much as possible, but at some point it is impossible.

Anyway I am posting because my unit blew up last week and I wanted to post some pictures. The funny thing is that it all happened when I was trying to upgrade to the latest Malaysk's ROM ... xDDD not that it was Malaysk fault, it is just a coincidence.

I was in my car on the evening, not a hot evening, and suddenly I heard a "pop" and the unit went black, after, smell of burnt circuit... so bad news. The unit never came up again. I attached some of the pictures.

It looks like the amplifier blew up, but I do not think it was a reason for the whole unit to stop, maybe to have bad sound, or no sound at all... but not to stop. Then I saw some other chips that also look like being burnt, I still have to check that, and there's also another part that is loose

Any help will be appreciated.

I have contacted KGL, but had no response yet... If I do not manage to fix it, I am planning to buy a new motherboard, or if anyone has one to sell, I will be interested. Please PM me.

Here the pics (for higher res and more pictures, see : https://drive.google.com/folderview?id=0B_Ddw1tZpHyYd2VsamJjSktjUTQ&usp=sharing)

cheers.

PS: bloody hell, no way to resize images on xda !!! what cr@p is that !!??

So you also had the RM-MD11? Ive been trying to install the correct MCU for this for almost a year and couldn't find anything that would tell me exactly what version of img to install. Do you have the correct MCU file and or a place I could get it?
[MTCB Android Head Units Q&A] xrapidx:
New generic 3G dongle arrived (the one recommended here a few times) - works the same as my current one - either doesn't - or does - and you need to keep restarting to get it up.

Powered hub doesn't make a difference either...

I think some of these units are just crap... and you either get one that works, or one that gives endless hassles.

Question - GPS Audio Mixing

I have a question about the GPS audio mixing on a Joying RK3188 (Andriod 4.4.4) unit. In the GPS settings I have mixing enabled and the ratio set to 10.

Thats what I was referencing when I was talking about the multiple MCUs that people have installed. I was looking for someone who had the RM-MD11 and installed the correct MCU on there so I could know what to put on there. What does the Dark Leo MCU do differently BTW?
[MTCB Android Head Units Q&A] warr4768:
I have to agree with you,unfortunately it has always been hit and miss with Chinese products not just electronics. I scan through this forum regular as I have a headunit and see most people struggle with a 3g dongle, I did. I have suggested to people just to get a mobile wifi, it connects straight away with 4g speeds ( if you are in a 4g area that is). They might be a little more expensive than the dongle but it's hassle free.

Thank you to everybody for creating this thread! The amount of info is scary! I must admit that I haven't read everything on here hehe! It will take a year! I'm thinking of pulling the trigger on one of these units for my Audi A4 B6 ( http://kaigele.en.alibaba.com/produ...2008_with_mirror_link_GPS_Radio_function.html ) If anybody has the same or similar unit I would love to hear what they think of fitment and what I could expect out of the box. I will obviously install a new rom as the sleep issue seems to be a major one.

Also if somebody can point me in the right direction with regards to extra hardware needed to make this unit as functional as possible.

Thanks in advance.

Welcome back pakidermo5000. I think if you upload pics as attachments to a post, they show up larger.

Go to Settings -> Factory Settings -> 126 -> Audio and adjust the volume down for radio, or up for sys.

I'm wondering if this is a RoadMaster, which is definitely in this "family" of headunits. Have only heard about those fabled devices, but never saw someone that had one.

Depending on which reseller you go with, they should include the necessary canbus adapter and fascia for your Audi. If you keep your expectations appropriate, you'll be pleased with the outcome. These are definitely not of the same caliber (build-wise, or fit & finish-wise) as the major Japanese brands, but the functionality makes it all worth it.
[MTCB Android Head Units Q&A] yellowkazoo:
Yes, I have fiddled with this...

However, the problem that I am having is that the system audio level is much lower when the radio app is running, but normal level when the radio app is not running.

If I turn up the system audio level then it is loud when the radio is not running and soft when the radio is running.

If I turn the radio level down to make the system level audible. Then if I am listening to the radio at an audible volume and switch away from the radio the system volume is very loud.

I would like to have the system audio and the radio audio level. But like I said, when the radio app is running the system audio gets lowered or muted.

Any ideas how to fix this or even where the problem lies? Is it in the radio app, the MCU, or somewhere else?

Thanks guys for all your expertise
[MTCB Android Head Units Q&A] xrapidx:

I have a new one that google couldn't find, I have a KLD (eonon) that has developed a high frequency buzz only when the audio originates in android (think: google play or pandora). IS the audio in these units sent from the android SOM to the main board via the ribbon cables? I'm trying to narrow down where to look for my noise.
[MTCB Android Head Units Q&A] pk313:
Welcome back!!

From pics I see bad news for U

Seems to be a problem in the supply side of the mother board...pins burnt on tda amplif are related to the supply line if I see good...so you have to identify at 99% a capacitor failed close to a transistor ... may be near to the usb out plugs..that had genereted an hi voltage pick flow on the motherboard...and pray that other parts are not damaged

I don't think that's problem was generated by tda7388. ..

So I downloaded the last available KGL rom - and so far my 3G has worked after about six restarts .

BUT - I started the radio - and I'm picking up frequency noise - no station though, I've tried changing the various chips, some give sound, some nothing - what can I do to try and see if its possible to get my radio working? I've installed a antenna amplifier - and the wiring inside looks ok?
[MTCB Android Head Units Q&A] SilverViper2k:
I did some testing by installing other daydream apps. Those changes are not reflected to the screensaver. Also, dream should only start when docking or charging, which isn't applicable for our units.

I did notice an app starting in catlog: com.microntek.clockscreen. I also found an app installed called Screen Clock. Most likely that's it. I could disable the app there but I wonder if I could edit its settings..
[MTCB Android Head Units Q&A] kevant69:

[MTCB Android Head Units Q&A] Twilek:
Thanks for the suggestions but I found the solution (which should help with the update problem as well). The touchscreen only radios actually do have ONE hardware button and that is the reset button. With that you can control the recovery menu (although it´s quite clumsy) and you can flash a new rom without android prompting for it. I have switched from the stock joying rom to the custom malaysk rom and been very happy with that (you will loose the ability to video stream via airplay).

Hi,

Please, if anybody could help on this:

On my GS, if I short-press the power button (volume knob) it toggles mute. There might be similar functionality on your unit.
