[MTCB Android Head Units Q&A] Hisma:
right, I don't bother with BT audio on my HU, because it's so easy to load up a SD card w/ all my music and play locally using poweramp.

Really this HU does everything I want it to do fairly well, except for voice control. Google now does an okay job of most tasks, but again if I could dial contacts imported from my phone using voice commands, that'd really do it for me.

Btw to the guy that said they wouldn't consider this HU if they already had an infotainment system... the mazda infotainment system is universally regarded as terrible. Slow/ugly tom tom maps, clunky voice controls that takes almost a minute to place calls due to overly verbose voice prompts (I never used it even tho it worked), dark & low res 6" screen, I could go on. My cheap android HU is a massive improvement. I don't miss the stock unit one bit. Waze maps & poweramp for music already blow the stock unit away.

Check factory settings
[MTCB Android Head Units Q&A] JEMShoe:
Thanks. Apparently, the HueFei HUs came with a custom version of the Settings app (settings.apk) that do not allow apps to either create the Services category or modify it (add entries). I wish either they would provide an uncrippled version of Settings or I could get some help in fixing it (I modified the accessibility_settings.xml file and was able to add the Services category but on the JYHU the apps still cannot add entries to it).

I am quite frankly getting tired of fighting with this radio...I don't have time for this; I would rather have a safe simple working unit than an unsafe (or distractive) complex poor quality half-way working unit.

sorry for ranting so publicly.
[MTCB Android Head Units Q&A] Sasha0574:
I did now, thanks. Gotta take it to the service anyway, so... I'll have them install me one of those aswell. Main concern is whether I'll get it to work now at all.

Hey guys,

Does anyone know if its possible to change the boot logo on an installed stock ROM that has root via *#hct#root# method?

Its easy to change the boot animation car-brand logo, but how to change the first static boot logo with the little Android Kitkat robot? Here is pic from other user who asked on page 1572:

It seems this boot logo is compiled into the kernel or as initlogo.rle

I tried to edit a few different HA stock ROM update.img but always error loading the img. Tried with Firmware Factory Tool v3.4 and RK3xxx Firmware Tool, which both have specific function for changing boot logo. Does anyone know a working method to change this boot logo or remove it completely? Can it be possible without flashing ROM somehow? Edit init.rc? Flash a patch zip?

So i made the conversion by just replacing the chip and indeed sound is way far better!

Only question i have is when i turn on or off Head Unit i hear an instant bass sound.. Nothing really annoying just wondering if it is something i could fix or just leave it as is..

No rear usb on my unit

hello ,

after upgrade with recent Malasyk rom/mcu i cant mount my rear usb, its ok on the front.

i ve try with many rom and mcu;

And when i listen the radio and put one usb key on the back, the radio stop, cant find any station; I must reboot it.

however all is good

I'm not the only one to have this problem, what can be the solution?

[MTCB Android Head Units Q&A] rcll:
Thanks for relaying your experience dsa. You're right its not a big deal but I think it would be nice to use custom bootlogo. I kind of like a clean look so could do without the Kiktat robot in the corner of the stock bootlogo on every startup. Disabling the bootlogo entirely would be fine or just placing a full black image. I read some kernels will use your own initlogo.rle if you place it in root, if thats the case with these kernels it would be really nice solution and not require reflashing the ROM. If there is a way to do it by editing files or flashing a recovery zip to patch an installed ROM that would be ideal.

I think Malaysk just added custom bootlogo on his latest builds so he must have figured it out. I found a bunch of tools for Rockchip ROMs which have whole section dedicated to changing bootlogo probably for easy manufacturer branding. I can't seem to load any of the stock HA update.img without error though, here is a pic of Firmware factory tool v3.4 to see:

Please help

Hello,

i have a problem with my usb-plug in my radio

What information do you need from the radio . Unfortunately I can not post link

When I connect the USB , the music begins . I can drive with my car 10 min and everything is ok.

Suddenly stops the music and the hymn go 10 seconds backward and runs quite normally and this repeat all the time.

I have tried different USB sticks (8-32 GB) (NTFS,FAT32)

I have a video of the problem. Where i can post it ? It´s on youtube.

Please help

How easy is replacing the chip?

I'm really bad at soldering... in fact, I've resorted to using a blow torch a times.
[MTCB Android Head Units Q&A] Billkaza:
You will need an average skill in soldering..

I used the easy way and cut the old 7388(made it useless) and then desolder the remaing pins and cleaned remaining solder paste and then put new.
[MTCB Android Head Units Q&A] Tutti-frutti:
Any suggestions on using a mono or stereo connector? The BT module itself is just mono, so I guess I should get a mono connector. Stupid thing is that the HU came with a mic with stereo-jack.
[MTCB Android Head Units Q&A] Sasha0574:
Thanks... just got back from the service with it... the trouble is, the screen is dead no matter what they did. The touch buttons light up, they flicker on pushing the reset button, but there is nothing to be seen on the screen itself. Completely black and dead. Only these guys here have no way of knowing what exactly died in there. They don't even know where to begin diagnostics
[MTCB Android Head Units Q&A] hadjistyllis:
Yes it also works ok, not perfect but works well. I prefer instead remove capacitor to seperate mic i cut pin 4, its the same thing. I solder pin5 from front bt module pin because pin4 and 5 are very close and its almost impossible to solder them without remove mainboard (i'm lazy hehe).

---------- Post added at 10:31 AM ---------- Previous post was at 10:28 AM ----------

Use mono (also stereo is ok if you just solder + to upper pin and - to lower pin, leave middle pin empty)

Does anyone know how the remote steering wheel controls work?

I don't have any, but would like to add some control buttons on my centre console to allow fingertip volume adjustment etc from where my hand naturally rests while driving. I can add the physical buttons easily enough but cannot find out how the actual control logic works. Essentially I want to create a steering wheel controls emulator.

Does each button on a steering wheel simply connect a different fixed resistance between the HU steering wheel input wire & ground/+12v? Therefore a set of fixed differing value resistors tied to each button would register with the head unit & allow calibration of the sensed resistance to a specific function?
[MTCB Android Head Units Q&A] Sasha0574:
For now I would rather not touch it, since it's less than a month that I have it. See if they will replace it... dunno...

By the way, long press into hard reset appears to boot it into recovery if I am to judge by the flickering of the touch buttons, but nothing shows on screen.
[MTCB Android Head Units Q&A] Sasha0574:
I looked at their videos, and I know they actualy encourage replacing defective components by yourself with ones they send you, but the thing is even the guy at the service said he has no idea what this maybe. Works with this kind of units from 2008 and didn't see this thing happen before. Plus being a capacitive screen, it's rather new to him and he doesn't know where the problem may be. He took some measures there and got nothing but scratch his head...
[MTCB Android Head Units Q&A] Sasha0574:
I'll just wait for the answer from these guys first, and then probably do it. Though most likely I'll have to go back to the service since I have no soldering equippment, not to talk about such a button.

[MTCB Android Head Units Q&A] halloj:
There are two different systems. One is like you described, a network of different resistors. Hyundai/Kia use the resistors. The other system

utilize the Can-Bus for SWC. The resistance is not critical since you calibrate when you store the different buttons. Must be different for different buttons of course. That's my experience playing with that on the bench. I've seen from 10k ohm or 1 k ohm and down systems. On my Hyundai's/Kia's I'm using key one and keyground.

It's not possible to get these details from your phone with bluetooth because it is not a "real" bluetooth module like your phone. It's like an headseat.

But you can get phone signal strength and phone battery level in status bar using CarService app on your head unit and RemotePhoneStatus on your phone.

This feature will be available soon with the incoming new version of CarService. It will allow making calls by voice commands using "Ok Google" command
[MTCB Android Head Units Q&A] Hisma:
fantastic! Are you the author of the carservice app? If you happen to get this working I will gladly donate for your services. To me having true hands free calling is the most important standard feature missing from the HU currently. The main things the HU should do well is play music, navigate, and make calls.
[MTCB Android Head Units Q&A] Sasha0574:
That I know... but as for realizing that it has booted... that one is tough on mine... radio was not on, the native player was not on, I only use the JetAudio player and that one does not auto-restart when the unit does. And since I have no knobs on it, I also can't check that part. Howevere, looking in a bit of darkness, the touch buttons appear to flicker when I long press the reset as if the unit is rebooting and going into boot mode. But there is no way to confirm since the screen is black. Though, for the love of it... I actualy didn't understand what the guy was doing with that piece of tape there...

thanks for the video, even if it is not my favorite kind of music, the girls are very pretty ....

the question I asked was because since I wanted to format the stereo, I would have already installed the new version if I can ... worthwhile in some way to complete or assemble the different versions, I would be very happy ...

one last thing, I read on the front page that the important thing for the Android update is to respect the resolution of the screen, while the part the processor is compatible, you confirm to me what I can or go bootloop ??

thank you very much for your commitment.
[MTCB Android Head Units Q&A] Sasha0574:
1. NEVER EVER use NTFS formatting on these units!

2. Is your music playing normally on some other device from the same stick?

Hi.

Sorry for my english

Two question

1 someone can link the easyconnect apk in last Malaysk rom?october version i mean

2 someone can explain me why if i have canbus i cannot set a steering wheel buttons with determinate app?it is only impulse from out source to head unit so a software mod should set the linked app. Why no?

[MTCB Android Head Units Q&A] Sasha0574:
1. Dunno, didn't try, can't answer...

2. You will most likely never manage to do that, since that impulse, as you put it, does not go to android but to a basic function of the device itself. Most likely controlled by the MCU, and neved designed to change apps but to mimic the functions of your stock car unit.
[MTCB Android Head Units Q&A] Tabs78:
Ok.

if i push phone button on wheel i see on my unit screen a image of microphone but i can not do anything

Inviato dal mio SM-G920F utilizzando Tapatalk
[MTCB Android Head Units Q&A] Sasha0574:
You can't do anything about the button's function. As far as the icon you see.... root it, find the icons depository, simply replace the icon and you can see whatever you want when you push the button...
[MTCB Android Head Units Q&A] Tabs78:
So you mean that impulse starts an image on device and not an application?

Inviato dal mio SM-G920F utilizzando Tapatalk
[MTCB Android Head Units Q&A] Sasha0574:
I mean that button starts a function in the device core functions. Functions are monitored by the android system and then that system gives you an image on the screen corresponding to the function, so you could have a representration of what happens. Same with the image that appears when you open your doors. A car with the corresponding door opened. No matter what you do, when you open the door, it will trigger the image with the car with the door that you opened, it will not start your favorite radio station. Or maybe it can, but for that you will need some pretty damn high programing skills. If it's the image that bothers you that can be changed, and quite easily. But some functions can't, simply because they are not mapped within the system. You can do it yourself, but only if you become some kind of programing guru, like Malaysk for instance.
[MTCB Android Head Units Q&A] Tabs78:
Ok thanks! And is not possible to associate a tasker activity to the appearing of that image?

[MENTION=3590033]Malaysk[/MENTION]! Can you please include by default in your future ROMs also the "Disable Fullscreen Keyboard" module for Xposed framework? See:

http://repo.xposed.info/module/com.shubhangrathore.xposed.disablefullscreenkeyboard

It is very, very frustrating to have by default the on screen keyboard cover the whole screen, while the top half of it is just an empty text box. This module disables this text box, and the app with its original textbox remains in background, just like on smartphones.

This was super-annoying especially on Waze, but also on most other apps.

On a HU, having this disabled is far more useful.
[MTCB Android Head Units Q&A] Sasha0574:
Given that when you touch the button on your steering wheel you practicly make use of three different softwares on that unit (the one on the can bus decoder, MCU and Android... plus the one governing your own can bus)... that already I don't know... Aska Malaysk, maybe he does. The simplest thing that comes to mind is for you to replace the icon that bothers you with one that doesn't "hurt your eyes"....

Thanks for the great work malaysk. I have a few questions.

1. Do I have to install the mcu update with the rom update? Or can I just leave it as the stock joying mcu?

2. I can't get the unit to recognize the update.img file I've loaded onto the GPS card. I've loaded the latest rom as a root file. Am I missing something? How do I reboot the device also. Only thing I know to do is turn the car off then back on.

Edit:. Figured out #2. For anyone wondering, you need to hold the volume button and press reset, then release the volume when the lights come on.

However, now I cannot install xposed framework. I get the following error when I press the install/update button in the installer app.

All I've done is update the rom. I didn't do a factory reset, or anything else. Did I miss a step?
