Stuck Android Logo.

Do you have any idea in this case what can I do to find out what kind of MCU unit I have, because I don't have acces any more to the screen to check in Settings-About.

I don't know witch MCU should I pick up (KLD, KGL, KYD, .... ) ?

Thank you!

-What is the correct syntax is:

lsd /mnt/internal_sd/Android/data "com.tomtom.gplay.navapp" /mnt/external_sd/tomtom/

lsd /mnt/internal_sd/Android/data “com.tomtom.iberia” /mnt/external_sd/tomtom

or

lsd /mnt/internal_sd/Android/data "com.tomtom.gplay.navapp" /mnt/external_sd/tomtom/

/mnt/internal_sd/Android/data “com.tomtom.iberia” /mnt/external_sd/tomtom

-There is a problem, why the tomtom folder already exists in the external folder.

-What is the function of the foobar folder.

Just to make 100% sure, please play a song on the music app (viper won't work with the radio app) and then open viper > settings > driver status, there you should see if it is really working or not... Viper can be sometimes a little picky ) but once you set it up it will not need more attention in this regard.

About the sub or firmware from your unit I'm afraid I can't help you, I have a different HU a hotaudio and didn't try to hookup a sub on mine.

DAB+ aerial

Yesterday I installed this aerial:

[IMG="DAB+ aerial"]http://kepfeltoltes.hu/151012/DAB__aerial_www.kepfeltoltes.hu_.jpg[/IMG]

I placed the aerial in vertical position on the windshield. I got a little better reception with Wavesink Plus app. With the stock aerial when I got 3 green signal signs, with this aerial got 4-5 green signal signs.
[MTCB Android Head Units Q&A] ADB100:
Any idea whether this has rooted firmware available?

I am looking to replace the head unit in my car with something from this decade and want to keep it looking fairly 'stock'. I am considering this:

http://www.aliexpress.com/store/pro...-Capacitive-Screen-Car/205122_1802218812.html

But obviously want to install a rooted ROM (or better still create my own..). Does anyone know if this has a ROM available or which one will work?

[MTCB Android Head Units Q&A] lysiong:
I just received the Joying JY-UQ128 which come with Rk3188 quad core, 1Gb ram & 16Gb storage. Can I post the internal component picture here? I also modify the internal mic to direct connect to bluetooth card(I have the detail picture). Sadly I accidentally broken the internal mic pin which made the mic unusable. I already order the internal mic & waiting it to be deliver. By the way, is that possible to adjust the mic sensitivity as I found up the mic sound is quite soft. The SGND & GND actually are link together which is a common ground as measure by multimeter.
[MTCB Android Head Units Q&A] Telemachus:
I have no clue what you did there. You connected the front mic to the Bluetooth module directly??
[MTCB Android Head Units Q&A] lysiong:
As you see in the picture, I lift up the mic+ & SGND pin of bluetooth card which I can use it to connect directly to internal mic.
[MTCB Android Head Units Q&A] ktibor69:
My rear USB port doesn't work properly. The device (DVB-T tuner with Wavesink plus app) and HU connection is lost after approx. 1 minute. The recognization is ok, but after the data connection is lost. The power is OK, I tested it. I think the data connection has issue. What does generate this issue? Hardware or software? The device works with front USB perfectly.

Anybody did make the front USB port goes to back? Where can I found the the data+ and data- pin of the front USB port in the HU?
[MTCB Android Head Units Q&A] Telemachus:
Yeah no kidding. The internal mic on both of mine is horrendous. Besides it points in completely the wrong direction for bluetooth calls.

Why not use an external mic for bluetooth mounted somewhere more useful?
[MTCB Android Head Units Q&A] gdsalin:

[MTCB Android Head Units Q&A] antvic:
Dear friend, I must be the most awkward person in the world; I get never the first. As you will see by the pictures, it doesn't work me.

I do not understand how the new TomTom GO is:

lsd /mnt/internal_sd/Android/data/com.tomtom.gplay.navapp "data" /mnt/external_sd/tomtom/com.tomtom.gplay.navapp/ When there is the folder files before the folder data. But the case is that TomTom GO continues to operate and supports downloading of large maps.

Terminal image you will see that the new com.tomtom.iberia folder does not appear. I don't understand why if I have done as I did for TomTom GO.

Indeed, in Startup Builder, published first and then turns on or is upside down.

Finally, if you think, check it out and tell me. Sorry to bother you but I still believe that there is something that escapes and don't know what it is.
[MTCB Android Head Units Q&A] lysiong:
I lazy to pull another cable for just the external mic. I believe that the internal mic that I order is much better than the original mic.
[MTCB Android Head Units Q&A] lysiong:
after checking the circuit, the bluetooth card mic+ is actually link to the red circle component & not the capacitor as mention by somebody in this forum.

Such a shame as this unit looks so much better...
[MTCB Android Head Units Q&A] KeiserSozeyFr:
On my headunit, I already use an external Bluetooth device (Volkswagen built-in Bluetooth) plugged to AVIN.

The new version of CarService I'm currently working on is able to handle calls with the RemotePhoneStatus client app installed on my phone. When a call starts, my app switchs ON the AVIN source and pause the music.

I paused my work for the new version for 2 weeks because I was on holidays but I'm currently returning to my work and I will try to release the new version soon on Play Store.
[MTCB Android Head Units Q&A] 7floor:
Looks very similar to PCB of my Joying unit.

This is the switch IC that connects the microphone to the Bluetooth module during active phone call and to the Android board the rest of time.
[MTCB Android Head Units Q&A] lysiong:
but if I connect the internal mic using the original circuit which connect to "switch IC", the bluetooth call seem to be picking out noise from internal circuit, it is very noisy.

I have an issue with playing DVD discs, audio discs play great but when I put a DVD disc in the DVD app opens you can hear the disc loading then the DVD app closes, I checked factory settings and the DVD option is set to yes.

[MTCB Android Head Units Q&A] Telemachus:
I would leave the switch alone, and cut a trace close to Mic plus
[MTCB Android Head Units Q&A] 7floor:
So what I tried:

1 - use only internal mic - poor quality, noise, insufficient sensitivity. I guess that the mic model is kind of wrong. It is small, like 3mm in diameter, and probably its electrical properties are not suitable for rest of the circuit.

2 - attached external microphone that was bundled with head unit - still the same noise and bad quality. This is because it connects simply in parallel to the internal one, and they conflict with each other.

3 - cut off wires to the internal mic and left only external - now there's no noise and sensitivity is good; only thing that remain is the acoustic echo if you turn the volume up too high - but this is an issue with built-in BT module which doesn't have any real DSP-based echo canceller, as do advanced car kits form e.g. Parrot.

PS. External mic is an ordinary condenser microphone capsule around 1cm in diameter, in plastic case on a long shielded cable; I've put it near the rear view mirror.
[MTCB Android Head Units Q&A] lysiong:
I might try to buy an echo canceller mic to try.

---------- Post added at 09:03 PM ---------- Previous post was at 09:00 PM ----------

I will left the switch alone too in case it is link to somewhere else. As I lift up the mic+ pin which connected to the bluetooth module, so no cutting is required :)

Yes, I saw it, but I have no idea if such modules are installed on head units ever, never seen any reports from owners.

And regardless of whatever this "Parrot" in factory settings means, I was talking about standalone car kits from Parrot, which were owned by me - their sound quality was excellent in both directions without any echo.

Thanks dsa8310

Hi dsa8310,

i am just with my device Pumkin Quadcore 800x480 since one week and after an installation in my car with many "fantasy" i searched for informations to the software. First i tried some MCU (after i understand what this is:)) and i found 2.72 the best for my KLD2. (Modded 2.55 causes Radio not working, 2.78 causes Volume control stops sometimes).

Then i tried the Malaysik Custom Room. The Options are amazing but the system where not stable at my device and the system was to overloaded with programs. But good work Malaysik.

Then i found yours, with many apps removed which i don´t need. Clean and with KLD Style (Next is nothing for me and jy too normal and blue). This Rom (latest with 20, with JY kernel) works perfectly to my device. After the first install i was very bored because the display wents darker afterhours. But no i know this is a feature and i know to deactivate it with PCV or Editing this special file which you talking every time about it... .sh something :).

So thank you for the clean Image!

But :) i have two questions. How can i disable autoplay of build in MP3 Player (because it has no shuffle play, its not perfect for me). And... how can i made "Data Usage" visible in System Settings? In Malasyk Rom it was available and there is a very important option, you can set WLAN as Thether, so system knows, thats not a real wlan since its provided by my iphone with crapy data plan. I tried "CARRisma"´s (Post) terminal code but doesn´t work. I tried Hidden System Setting and found a knoob for that but app crashes. I know the app is there and need them. Maybe anyone have a solution? Sorry for the bad english btw.

EDIT: I found this, but i can´t find the file:

WITH ROOT :

1. Open a file explorer.

2. Go to cust/hw/eu/prop and open local.prop with editor and add these lines:

ro.config.hw_opta=999

ro.config.hw_optb=156

3. Save it.

4. You will see Data Usage option in settings.

Yes, you need to take these steps to correctly deliver the install-recovery.sh file.

Hi [MENTION=3590033]Malaysk[/MENTION],

First of all thank you so much for all your hard work in developing ROMS for us all. It is really appreciated.

I am hoping that you can help with an app that is not working with your latest ROM versions (RK3066 800x400) (KLD2.78).

the application is called "wikicamps" available from playstore: https://play.google.com/store/apps/details?id=au.com.angryrobot.wikicamps&hl=en.

The issue is that the application crashes as soon as it is run on your latest roms:

and

10.10.2015/ 10-Oct-2015 15:26 -

[MTCB Android Head Units Q&A] halloj:
You should only follow the first part. The second part is all about the internal mic. If you have KLD you only have to remove the capacitor

and solder the inner cable to mic+. The shield should be left open in the BT end. Since I recommend to use a 3,5 mm socket attached to the chassis which is

common ground. The shield is soldered to the common pin on the 3,5mm chassis connector and the lead to the tip of the same connector. This is all

described with pictures and also discussed in the thread. Use my signature. I've four installations like that and they all work. I'm using either a Sony mic

or a Parrot mic. The original Chinese mic is crap.
[MTCB Android Head Units Q&A] :
And where is your signature? :).

On KLD Device. Remove C32 and then attach a cable to Mic+, right (The cable is connected via a plug to the microphone)? Now But: "The shield should be left open in the BT end. " what does it mean? Must anything diconnected from the BT Card? I saw some pictures where SGND and Mic+ was disconnected. So i am unsure what to do really. Maybe a picture of the finished work should be very helpful to understand, but i didn´t find the matching one.
