[MTCB Android Head Units Q&A] jrgalang:
All, is there another way to reflash recovery.img? Reason I ask is I've already tried reformatting SD cards numerous times, swapping them and making sure only update.img is all that it has. But the prompt to update just doesn't show on Malaysk' latest ROM. When I go to recovery it's also unable to find update.img no matter the version I use or the SD card I use. I've also tried to use Flashify but it just freezes when I try to use the recovery zip found in the FS. Latest attempt I tried was to reboot to bootloader but the PC can't detect squat either even if I was already able to use RKbatchtool before on a defective unit. Thoughts?
[MTCB Android Head Units Q&A] mike.s:
I describe how to flash just recovery.img within the last week or so. Use search.
[MTCB Android Head Units Q&A] typos1:
Why coudu's ? Its way out of date now. Any non Malaysk ROM will have the launcher it comes with out of the box(ie KLDs have KLD launcher, KGLs have the KGL launcher and any others (JY, GS etc) will have the standard MTC launcher.

The KLD launcher doesnt have a widget - the music/radio/weather etc readouts are built into the launcher. You could delete the factory BT in theory (it may cause crashes) but no other app will be able to interface with the BT card, so it would be pointless, unless you try a BT dongle or something, not sure anyones tried that at all. You could also theoretically delete the factory music and video, but it may cause errors, not tried it so dont know best just disable them, but that may cause crashes also.

TBH I cant remember if the hard buttons can be remapped or not, checkout the first page and [MENTION=434511]agentdr8[/MENTION]'s apps. You cant add widgets to the main screen of the KLD launcher but you can to the other screens (swipe left or right when on the main screen), or you could install wither the KGL or JY ROMs or the KGL or MTC launchers on the KLD ROM, if you dont like the KLD launcher. Or as with any other Android device install a launcher from the Playstore.

I'm trying to get omniswitch to run on boot using instal-recovery I have start up builder and I edited the file to add niswitch service and it hasn't work could someone tell me how to correctly do this?
[MTCB Android Head Units Q&A] SilverViper2k:
Yeah I have Spotify force closing on me as well. I also have the wifi not connecting to my iPhone's hotspot. Both issues are very inconsistent and therefore hard to find the root cause. Sometimes they fix themselves, sometimes I have to disable wifi on both my phone and the HU, sometimes just on the HU, sometimes it just works automatically, but most of the times when it doesn't work, only rebooting the HU solves the issue.

Spotify seems to start properly when I don't have wifi in most cases. But after a force close I can't get it to run even after I disabled wifi. Manually force closing Spotify doesn't help either then.

I just installed a logcat viewer so hopefully I can figure out why for both my issues. Of course both worked charmingly once they knew I was on to them :p
[MTCB Android Head Units Q&A] slackmartian:
I suspected the WiFi as well. Let me know if you find out anything.
[MTCB Android Head Units Q&A] SilverViper2k:
If you disable wifi and reboot the HU, does Spotify launch properly?
[MTCB Android Head Units Q&A] slackmartian:
I've found that in order for it to work I must start hotspot on the phone before starting the car, although sometimes that doesn't work either. If I disable wifi Spotify won't run.
[MTCB Android Head Units Q&A] SilverViper2k:
I have the same with wifi. I need the Personal Hotspot page open on the phone and then turn the key, make sure the page stays open. However, if I don't do that or something screws the process up (like me paying attention to the road instead of the phone), it doesn't connect. The hotspot is displayed in the wifi settings on the HU, but any connection attempt fails, it doesn't even try to attempt to obtain an IP address.

Once it is connected, and I disable wifi and reenable it on the HU to get Skype running, it sometimes reconnects and sometimes it doesn't make connection when I turn the wifi on, making both issues very annoying together.

I have a JY btw.

[MTCB Android Head Units Q&A] Rabidoe:
The main reason I wanted to use Coudu is for the partitions, I want more internal memory, the 1GB is not enough, it also deletes a lot of the default apps that I don't use. I like the KLD launcher and want a new flash that maintains the look but with root and partitions.

The file repository has a Coudu last updated in May 15, is this out of date? If so have you got a link to a recommended flash?

Thank you for your help

Malaysk's rom repartitions your memory to 2GB i think and is prerooted....Im like you i prefer the KLD launcher so i installed his "Standard Launcher" (which is i think the one used on JY units) then updated the Launcher APK with the Klyde one.

the latest rom is July 26

[MTCB Android Head Units Q&A] agentdr8:
Any of Malaysk's roms prior to July 7th should have the KLD launcher, and expanded partitions. You could also install his latest rom and just replace the JY launcher with the KLD one. Links are in his signature.

Brightness nightmare

Hi,

I have been using a rom from Malaysk - great work here no doubt - but the brightness controls a re still a mystery. Theres an option with Auto, Auto intelligent and Dark, that has a life of its own and changes the brightness to a very low level independently of any setting or time of day. I even disabled all the other brightness modules in Xposed just to exclude any connection . If I manually change the brightness it folds back to a lower setting by itself after a few seconds. And theres no apparent way of disabling this control either. :(

Doees anyone knows what on earth is going on with the brightness control here? Obviously, I am missing some obvious path? :silly:

Thanks

Ricardo
[MTCB Android Head Units Q&A] typos1:
No, it works on DVD only, which is separate from Android.

Coudu's is 3 months out of date, DSA's ROMs are the "replacement" for coudus, ie very similar to the standard ROM but with some (improved) mods, including a larger data partition, they are the versions that have been uploaded to the fileserver since about May in the normal "firmware" folder. Malaysk's is a full custom ROM, Malaysk's is a great ROM, but I suggested DSA's rather than Malaysk's because DSA's is closer to coudu's slightly modded standard ROM, which is what [MENTION=6862556]Rabidoe[/MENTION] seemed to want.
[MTCB Android Head Units Q&A] SilverViper2k:
I did some logging. I found facebook errors when starting Spotify and may had to do with Facebook not being installed. I installed Facebook but it didn't have any effect.

I found the following line only present when it works:

W/AsyncHttpResponseHandler(2414): Current thread has not called Looper.prepare(). Forcing synchronous mode.

No clue what it means other than the thread will have to wait until it receives a HTTP response, which it can't when there's no connection.

Anyway, I also tried installing a firewall and blocking Spotify, but that doesn't help much which surprises me.

Regarding the wifi, I do see some inconsistent loggings of the following:

E/RkWifiCtrl(422): rk_wifi_load_driver:(rmmod)

and/or

E/RkWifiCtrl(422): rk_wifi_load_driver:(insmod)

Sometimes one or the other with different results in connectivity.

I'll keep testing and hopefully finding more correlations ...

[MTCB Android Head Units Q&A] agentdr8:
Assuming you've also disabled XposedMTC, check your /system/etc/install-recovery.sh (or install-recovery-2.sh) to see if maybe dsa's brightness control is conflicting with the app Malaysk has integrated.
[MTCB Android Head Units Q&A] cocchiararo:
i think the Xposed module that can control brightness updates each minute.
[MTCB Android Head Units Q&A] rricardouk:
Xposed all off. I think it might be the brightness controls in Settings (Auto/Auto Intelligent/Dark) that are causing this havoc but cannot figure out what they actually do - since they all darken the screen to almost 0 - or where they get the values to change from or even disable it.

I can confirm, downgrade mcu dont work

I tried all mcu(stock and darkleo), 2.20 - 2.64. I really dont understand. I tried anything i can find on the net! Im really out of idea
[MTCB Android Head Units Q&A] typos1:
Getting from all what ? - No one one has mentioned the KGL WinCE headunits in this thread., AFAIK. Its highly unlikely youd be able to dual boot with Android because a) youd have to write some special software to be able to do it and b) the specs of the WinCE versions are so low (512Mhz processor, 256Mb of RAM) that they wouldnt be able to run Android, well not any version since about 2.2 anyway

No quotes in your post, so not sure who you are talking to and what post they were asking you to look at, but the specs you post are deffo NOT anything to do with the units in this thread, or the units in the AN21-U thread. They may be from the Ownice thread, or possibly the Newsmy thread (but I dont think so), so you could try there or Google.

What was your problem ? Not heard of anyone not being able to downgrade their MCU before, why did you want to ?
[MTCB Android Head Units Q&A] pants001:
I dont think it was being able to downgrade, more so that it didnt fix his problem.

My problem is, radio dont work. Somebody said to downgrade my MCU for get it work again but i tried all MCU and noting work(2.20 - 2.64)

Each time i tried a MCU, i put my config for my mazda canbus in factory option(steering wheel button work well) But no succes. I can confirm, radio worked on 4.2. Its only since im on 4.4.4 with a different MCU

Im out of idea
[MTCB Android Head Units Q&A] pants001:
Radio is controlled with MCU so my first thought would be the change in MCU rather than android update.

What version did you have prior to update?

I always advice to take a photo of your current setup prior to updates so you can always roll back.

Hello typos1 / everyone,

I'm not looking to start a debate about which model is better then the other. I just want to ask a point blank general question. My first experience with these unbranded china head units was 7 years ago, when they were very early first generation WinCE units. I understand these first gen units were very unstable (and my started failing after about 5-6 months). That's in the past. Now fast foward to present day, and these units are several generations advanced, and pure Android OS (supposedly makes for a better software/hardware build). All the major bugs and quirks should be worked out by now. And the major advantage now is the support of the xda-development community. That alone should make it light years advanced. So I decided to jump back in with these units :fingers-crossed:

However, I purchased a KLD universal unit (RK3066 / KK4.4.4) three weeks ago. I didn't even modify it yet and it suffered a crash within the first week (it was still in original factory state). I updated the mcu/firmware combination to a newer firmware with the help of dsa (not custom, not rooted), and everything was running great. Then two weeks later it failed again. Now I have a black screen and the only thing it does is beeps when I try to reset. Dsa beleives my unit most likely suffered from a defective SoM board. So I'm in the process of having the seller replace it (eonon).

(BTW - dsa was great and in no way am I placing any blame. Let me repeat that - HE WAS GREAT!!!) :good:

So my general question is this - are these units still hit or miss? I mean, are these units reliable, regardless of whether they are modified or not? I know I had the bad experience with my original WinCE generation (granted that was a long long time ago in "tech" years), and now this recent issue with the Android unit. I would have though all the bugs would have been worked out. Anyways, if someone just wants something that works right out of the box, are these units for them? Or will these still have nagging issues :confused:

Thought - opinions - or recommendations (recommendations via PM please, I do not want to tick off the xda gods). I just want to know what I'm getting myself into again - whoo hoo :silly:

gg :)

Have you tried going to Settings > Factory Settings (126 passcode) and fiddle with the Radio setting? There should be a couple i.e TDA**** or TEF****, click Apply and restart every change and load the radio for every restart to see which of the option works. HTH

---------- Post added at 02:53 PM ---------- Previous post was at 02:29 PM ----------

You're on the right track on the re-mapping effort. I'd suggest downloading a file manager app, i.e. ES File Explorer, then as that post states: navigate to either a) mnt/sdcard or b) mnt/internal_sd depending on your unit. If you use ES File Explorer, just swipe from the left most part of the screen going to the right to show some options which will display which folder does your unit have (including the external_sd folders).

Once you determine which folder you have, using internal_sd as an example, press the +New on the right-side of the ES File Explorer app and create a new folder. Name it mtc-keys

Open the newly created mtc-keys folder and again, click +New of ES File Explorer and this type create a file. Name the file as mtc-keys.ini ... after the file's created, click on it and open it using a text editor (ES File Explorer should have ES Note Editor, which you can use). Click the 3-dots at the top-right of ES Note Editor to select the "Edit" option, and you'll have to enter the following line as mentioned in the link you've provided:

app_XX=com.microntek.bluetooth

Where XX in app_XX needs to be the key code that your AMS button triggers. One way to know is by downloading / opening CarService app from here: http://xdaforums.com/showpost.php?p=53678587&postcount=1179 . Open CarService and at the left side, when you press the AMS button you'll notice a new row will be added containing the key that you'll need. Take note of it and go back to your mtc-keys.ini file and replace XX to whatever value you saw in the CarService app. You should be set then.

If it still doesn't work, make sure you've enabled the mtc-keys Xposed Module by opening Xposed Installer > Modules > mtc-keys must be checked. You must also restart your head unit after. HTH

EDIT: As for the dash cam app.. you can use Caroo and set it to start recording on launch. Then use the bundled start builder (for Malaysk anyways) or install AutoStart app in PlayStore so it loads whenever the unit boots up.

Pumkin auto

Hi guys, i'm new at this forum but I got some info and questions about Pumpkin auto units.

I have this one: Pumpkin Auto KD-C0341, 7" android kitkat VW-look, in my VW golf mk5.

This is a RK3066 unit with android 4.4.4, KLD unit. I'm really keen to get the sleep function, I've however tried 4 different MCU versions with no luck. Darkleo MCU, locks amplifier settings, meaning fader isn't working no more. The sound is also worse than standard. v2.55 and 2.64 also have bugs on this unit: Radio does no longer work, music can't play with GPS running (under settings, the point where you can choose "mixed" is greyed out).

Finally i've contacted Pumpkin Auto, which send me KLD v2.67 MCU, and now it's back to normal. Sound quality is good again.

Does anybody know why the menu for sleep settings won't appear on my unit, regardless of what MCU version i'm running?

I can checkmark RGB led lighting and RDS, and make those functions appear in the settings. But no sleep-settings:(

App settings gone

Hi guys,

I had app settings installed, so I could control the dpi for waze, since it shows very strange in my screen.

But suddenly app settings was gone, after the unit powered on, and the dpi came back to default.

I tried to reinstall app settings, but I got an error message saying it could not install app settings. Tried to uninstall and reinstall xposed framework, but it didn't work either.

App settings doesn't show up under settings/applications.

Mixer question

Hello Guys,

Can someone please shed some light on the mixer functions in our devices?

As far as I know these units use tinyalsa. The funny thing is, if I install alsamixer (https://play.google.com/store/apps/details?id=com.skvalex.alsamixer) it can't see any sound devices. If I run tinymix, I have zero controls for my default device. The command "alsa_aplay -l" however lists all my sound devices properly. I might missing a very basic thing here, but I can't sort out what controls input/output sound volume, and generally the mixing functions in my unit.
