Hi,

I've just read this entire thread so I have a few questions.

which apps have limitations with the 800*480 screen?

Whats the benefit of pure android?
I found this quad core with WInce and unsure of the benefit of android only units
aliexpress (dot)com/store/product/TOYOTA-Corolla-EX-Android-Car-DVD-Navigation-Android4-1-dual-system-multi-point-touch-capacitive-touch/432439_1139125630.html
or is it just a fake listing?

I'll leave the resolution question to those that are more familiar with the topic. I have owned both a win ce and an android unit, and the major benefit of android is access to apps. If you're just looking for a radio that just works* and is limited to built in functionality then win ce is for you. However, if you want to customize and tinker you're going to be very disappointed with a ce unit. Unless of course, you are a developer that knows how to write ce apps.

There are merits to both options but for me, I found the ce units to be far to limited for me.

*by "just works" I mean works as well as a rushed to market with less than adequate quality controls can "just work".

Just spent some time doing some optimisation.

On a clean factory reset install I can now get startup to 15sec down from 30sec. Looking promising as only optimised 4 files so far.

Getting further on the MTU mods now too.

Have recoloured my Radio totally now doing a midnight blue theme. Changed the settings for the Radio Pty as mine kept saying Educate when it was a rock station.

More soon.

Hopefully people are still interested in this unit. I think its potential is just starting ;)

That boot optimization time is fantastic, you are helping to convince me to buy this.

So anyone know if SWC works with 3rd party apps?

EDIT:

I just looked on android-caraudio and they now have a section for 1024x600, and every single one of them have the brown interface with the 1GHz dual core A9. :(

ANDROID UTILITIES FOR THE UNIT
Adb drivers and others (thanks to @donaldta)
http://www.rockchip.nl/downloads/


Get Into Recovery
1 Press reset button and power button together
2 After about 5 secs release reset button, but keep pressing power button
3 When booting screen appears release power button.
4 It boots into recovery.

Get sound when in reverse (thanx to @Keylo Lo)
http://xdaforums.com/showpost.php?p=50966200&postcount=88

Engineering password (thanx to @blankers)
If anyone needs the engineering password in the settings menu it is "126"

Android Upgrade
You find the files here: http://www.sendspace.com/filegroup/AO60pBOod95Bo36CpjpUsw"]http://www.sendspace.com/filegroup/AO60pBOod95Bo36CpjpUsw

It works with the microSD card. There is a program (in chinese) to generate autoboot sd card, and also the Android image. You can find instructions in english on the word file.

--Update-- This is a file to create an update SD card for Android 4.0, not 4.2.2. Please, do not use it.


WIKIPAGE - Instructions to get root (thanx to @webdude12)
http://xdaforums.com/wiki/HuiFei_Android_Radio

You can also find there 2 files. A break apart of the Factory supplied image into their own individual images. The second one is a rom dump of the system folder, recovery and boot images.

ISSUES
Unfortunately the first issues with the promising unit arrived. @webdude12 got a black screen while driving due to a broken clip (see attachment to figure out which one). One solution is to glue the clip so that it does not get loose. Not doing that can end up in major problems.

I wrote to keylo about some optimizations. In fact its a list of now 16 Ideas and comments. Will see if they will take the chance and improve the unit further :)

They already told there will be a 4.4 update

Hi Keylo,

hope you have had a nice weekend?

Any news on the iPod-Question?

Also I have one more note to you which is at a very high priority for me personally.
I think MP3s should be shown with their ID3-Information if available. Just like attached IDv3.jpg
Also in the Track selection. But best would be if you made a real library as I suggested in the list.

To see what I mean when tellingng library just see Google Music Player or PowerAmp for Android.
Those are media players that have a real music library. Also a search functionality would be useful.

For must buyers the Media Player (for MP3 Media) wil be the most important feature next to navigation.
This is the Mode the Radio will about 70% used on. So this is the App you should pay most attention for.

Just like sound quality in general.
Your sound quality is very good but that beep issue (you can hear the inducted noise of the generator
(the device that makes electrical power when the engine runs) when using preamp-outputs. It is not a
wiring issue by myself. Other radios work and it’s a problem also stated by others on XDA forums.
This issue mostly consists as I would guess your outer chinch connector wire would probably have
direct – not galavanic split – connection to the cars ground. This is where the noise is inducted most likely.

Guess I have to use a splitter adapter to solve that or even use high-level signals.

One more question to solve that issue: Can you support any digital sound cards? Like USB to SPDIF-Dongles?

I’m glad you are willing to help and improve your product even more. I hope you can capitalize or at least
benefit from my ideas and comments. If the unit gets even better I will also write to some sellers here in
germany and ask if they do not want to import your product to support you as good as I can.

I cannot even thank you enough!

Regards
Alex.

Im sorry to tell you they dont develop the software

I am sure they can request changes and maybe some will come but the good news is that this is developed with a standard SDK for Rockchip so update for 4.4 should be coming. Just maybe not many changes in the MTU side.

Well if it only would be possible to use PowerAmp or similar cleanly... I mean includung steering-control and autostart (okay autostart would probably be possible by own launcher service app)...

Well two another questions to you. guys...

1.) Has anyone checked why the beeping noise occures on PreAmp-Output and if there is something you can do against it? I guess it's hadware-related...
And yes I know about the High-to-low-Adapters... But I want to avoid this...

2.) Has anyone tried to use the iPod-App? For me it just closes a ssoon as I open it... What am I doing wrong?

That's great !

Unfortunately, I cannot help. I cannot get the computer to detect any new device when in bootloader mode. Moreover,. I have not been able to put my unit in bootloader mode from cold boot (I may have to unplug the unit, because booting up the unit to reboot into bootloader mode will not be possible if I brick the unit).

Did you manage to sign the MTU apks and boot the unit?

I have the same problem with the radio stations. Rock stations are considered "Religion", which, well, is another way to see it ;)

Sure. Just commenting on some of the people checking for units. I have been looking for units for more than a year before buying this one. They all had problems, incompatible apps, poorly build units, WinCE, single core, android 2.3, no capacitive screen, etc. There was always a promise of a new and better unit, but never arrived.
Then I decided to go for the HuiFei. I have to say that I am happy with it. It can be improved, yes. But everything, or almost everything, works. The hardware is good. You can listen to music or watch movies with no problems. I can run all the apps I need. I cannot sign in in Chrome, fine. There's firefox, but the stock browser works pretty well, and signs into google. Resolution might be an issue in a future, but I do not think you will be running a lot of apps on this. Remember, you have to drive, and clicking the screen is not easy.

On top of that, we have access to the bootloader, and to the source code. Improvements will arrive, probably soon. Just my 2cts.

I agree. Using PowerAmp as main player with button function would be great !.
BTW: no need for auto start. The unit auto starts the last app that was used when turned off. In the case of PowerAmp, it just starts, but with the last track on "pause". You just have to play it.

Sorry, no preamp in my car, no beep either. I remeber webdude had problems with the sound too. He had to buy something to fix it, you can find the info on the first post.

I do not use ipod.

Hope it helped.

I appreciate, but I do not dare to flash anything if I am not sure I can recover from a brick. You said you changed the settings of the app to fix the "religion" thing. What do you mean, are these declarations made in the apk ? I would like to learn do it myself.

No, the trouble is, I'm trying to design my own. I'm trying to design my own Android head unit, and I'm trying to figure out how to implement Bluetooth dialing.

Sorry, did not understand the question. I do not know what kind of headunit you are designing, but in the HuiFei the bluetooth module is not directly handled by android, but by the MCU. Maybe you can get some ideas if you take the MCU apks and reverse engineer them (there are the links in the wikipage). I do not think the kernel of HuiFei is of any use in its current state. Maybe you can try with other headunits like the OUKU.

See here:

https://developer.bluetooth.org/TechnologyOverview/Pages/HSP.aspx
https://developer.bluetooth.org/TechnologyOverview/Pages/HFP.aspx


Android devices typically do not support HSP or HFP from the client side (they do from the host side of course). Even on all of the head units I've seen, the bluetooth module is not truly visible to Android. The MCU passes along limited info and allows limited control through a native app.

You may want to take a look at this post:

He's making quite a bit of progress in examining how the MCU communicates with Android.

    This is a new thread for this car dvd that was first reported on comment #2224 of the AN-21 U thread.

    Probably you are here because:

    • you want to root your unit. Only units with ROMs 4.2.2 can be rooted (see below how). The only way to have a rooted 4.4.x is installing a pre-rooted ROM (see below how)
    • you have a problem (no internet, no sound, buttons do not work, bad mic quality, rear camera image not showing, door opening not showing, etc.
    • you want to upgrade your unit to a newer software that has sleep mode, personalized music app, personalized functions, root, xposed, can remap buttons, etc.
    All this is covered in this post and most of the problems that you can have are summarized in this post too. Please read this first post before asking. And use the search function of the thread, before asking. Thanks.

    TRICKS THAT MIGHT SAVE 1000 QUESTIONS ON THE THREAD
    Read below and here for basic questions asked and answered 1000 times.

    How to root my unit. Only 4.2.2 can be rooted with an app (see below). To have rooted 4.4x you must install a pre-rooted ROM (see below)
    Get sound when in reverse (thanx to @Keylo Lo)
    here
    Engineering/Factory settings password "126" (thanx to @blankers)
    This allows you to change logo, sound volume, SWC codification, etc.
    Activate USB debugging --> Go to Factory Settings and enter password "adbon".
    System sound is low compared to Radio--> Go to Factory settings and change volume levels
    GPS button does not trigger GPS app You need to choose predefined GPS app, in Settings--> GPS

    Get Into Recovery
    1 Press reset button and power button together
    2 After about 5 secs release reset button, but keep pressing power button
    3 When booting screen appears release power button.
    4 It boots into recovery.
    --Update 1-- some units without front USB have a different procedure
    Firstly power on the unit and then long press the power button and then reset. Then the unit will get three rings and you loose your hand on the power button and short press the power button again. (thanx @netay)
    --Update 2-- some others have this procedure (thanx @R4D3N)
    1. Turn off the unit by holding 3-4 sec the power button.
    2. Hold the RESET button + POWER button for 5 sec
    3. Release the RESET button and keep pressing the POWER button for 2 sec
    4. Release the POWER button and wait. The Recovery menu appears.
    5. With the Volume knob you can move up/down and long press on Volume/Power button to select the option.

    Get Into Bootloader
    The process is basically the same, with the difference that you need to have the computer attached to the unit via the front miniUSB (if you do not have a front USB, you will have to ask your seller how to get into bootloader mode)

    1- boot the unit as usual.
    2- plug the front usb of the unit to your computer usb.
    3- Then, push the reset button and the power button at once and keep them pushed. The reset button is the tiny pin next to the mp3 sdcard. The power button is the volume knob. You will hear the power cut throught the speakers.
    4- Release reset button and keep power button pushed. Now the unit will reboot. You will see nothing, just a black screen. Do not release the power button yet. Your computer will detect a " new hardware", that is the RolckChip. When you hear the windows noise of new detected hardware, you can release power button. It will automatically install the drivers.
    ------------------------------------------------------------------------------------------------------------

    HOW TO UPGRADE YOUR SYSTEM
    BEFORE UPGRADING YOUR UNIT YOU MUST KNOW
    • MCU your unit, there are many (KGL, KGL1, KGL2, KGL3, KGL4, KGL5, KLD, KLD1, KLD2, JY, GS, KYD, MD, BN, HA, MX), If you install the wrong MCU, you will brick your unit.
      To know which one you have. Go to Settings -->About
      If still not clear, see: here or here.
      If you cannot find it here, it probably means that you are in the wrong thread.
    • Resolution of your unit. 800x480 or 1024x600. If you install the wrong ROM, you will brick your unit.
    • Chip of your unit RK3066 or RK3188. It does not really matter, ROMs and MCU are compatible between chips.
    IT IS ADVISABLE TO BACKUP YOUR SYSTEM BEFORE PLAYING WITH IT
    Upgrading is supposed to be a safe operation, but you never know what can happen. So, before updating make sure that:
    1- To backup of your system the easiest way is download nandroid root from google play, and do a nandroid backup with TWRP format). Save it in your external SD.
    2- make sure you can enter in bootloader mode (see below how to)
    3- it is recommended to backup your apps and data (use titanium from google play). The update will do a factory reset.​
    FOLLOW THIS TO UPGRADE YOUR ROM AND/OR MCU
    0- Do a back up (copy the files somewhere safe) of your internal SD card memory. It will be wiped during the process.

    1- Download the ROM (Resolution 1024x600 or 800x480) and MCU (KGL, KLD, JY, GS,RM, MX, BN, HA) for your unit.
    ROMs--> repository This will get you a file named update.img. There are different "flavors" of ROMs.
    Code: 
    - [user=853627]@coudu[/user] (rooted, stock). Early v4.0 and v4.1 have some problems.
- [user=3590033]@Malaysk[/user] (rooted, with very useful mods, some come with NEXT launcher)
- [user=6041319]@dsa8310[/user] (rooted, almost stock)

    MCUs--> Latest MCUs by Malaysk are here . This will get you a file named mcu.img

    2- copy the update.img you have chosen to the root of your GPS card.

    3- copy the mcu.img for your specific unit to the root of your GPS card (if you do not want to update mcu.img, you can skip this step)

    4- insert back the GPS card to the unit. If no window pops up, reboot the unit. At boot, the presence of update.img will be detected and a pop up window will ask you whether you want to update your unit. It will automatically reboot into recovery mode and update your unit. Once done, remove update.img and mcu.img from the root of the gps card or you will be asked every boot for an update.

    5- In some Coudu´s (sd partition of 3Gb) and Malaysk´s ROMs versions, it is necessary to do a factory reset just after the first boot so that everything works properly.

    6- If you lost buttons or radio after the upgrade --> Go to Factory settings (password 126) and choose the proper canbus for your car and the radio chipset. You can change boot logo if you want.

    THINGS YOU MAY WONDER BEFORE BUYING A HEADUNIT
    Code: 
    [B]- Boot Up:[/B]: time is around 30s. 
[B]- GPS[/B]: GPS positions very fast. TomTom, Navigon, Sygic,  and regular off-line GPS work. Navigon and Sygic have some problems with some ROMs
[B]- Stand by mode[/B]: Latest ROMs and MCU have the possibility of choosing stand by mode with various times chosen.
[B]- Radio:[/B] radio stations are saved as frequencies
[B]- Bluetooth contacts:[/B] contacts are saved on the device.
- Works fine with Bose system (Audi)
- Possible ground loop noise that needs some tricks to be removed (see section problems) 
- Torque works and can run in parallel with A2DP
- ELM327 works (might need special app like CarService in very weird cases)
- Camera works (might be better to get the one with RK3188 chip)
- There is no automatic brightness control because the unit does not have light sensor, but there are apps that can help
- The touch screen is extremely responsive. It works as good as most phones.

    HOW TO ROOT AND INSTALL TWRP
    Instructions to get root (thanx to @webdude12)
    It only works for Android 4.2.2. If you want to root 4.4.x you need to take apart update.img and inject SuperUser app (this is only for experts as @coudu, @Malaysk, @dsa8310 ). The alternative is to install a 4.4.x pre-rooted image and you do not have to do anything else. See below in HOW TO UPGRADE YOUR UNIT section how to do it.

    If you want to root your 4.2.2, download Root Master 2.1.1 here
    Code: 
    1- Install the APK.
2- Make sure you are connected to WiFi and you have an internet connection.
3- Open Root Master (do not upgrade to newer version unless you can read chinese, The newest version has different options, all in chinese. Version 2.1.1 just has a button that says "root".))
4- Press root button
5- Chinese characters will flash across the screen.
6- A second popup box will appear, press the purple button.
    The app will automatically install SuperUser.
    This program connects to servers oversea sending hardware information. The downloads a script that will attempt to root the device. If the first script fails, it downloads additional ones. Future goal is monitor this communication with a data logger and find which script works, so that a unique program can be written to achieve root.​

    How to install TWRP recovery (thanx to Abdul_pt from Freaktab and 1-2-Hak and coudu)
    You do not really need to install TWRP unless you wanna mod the rom yourself, if you mod roms you will know that already.
    - a.t.m. you need a mouse to use TWRP because touch is not working yet
    - if you install TWRP, you will not be able to update the update.img and mcu.img the way it was explained above.

    If you still want to install TWRP:
    Android 4.2.2 800x480
    Download files here
    And follow the post by 1-2-Hak

    Android 4.4.2 800x480

    TRICKS AND MODDED APPS THAT DO WONDERS
    • Install app without adb when regular install does not work
      Sometimes the app won't install normally and you need to sideload it.. This means that you need a computer and adb wifi. There is another way with which you won't need a computer. You just need to install a terminal emulator (you need root ).
      1- Download the terminal emulator app you prefer
      2- Download the app you want to install to /mnt/sdcard
      3- Open terminal emulator
      4- On the terminal navigate to /mnt/sdcard by typing
      Code: 
      - cd /mnt/sdcard
- su
- pm install "NameOfTheApp".apk
      Done, you are app is now installed.

    • Modified Radio Apps
      To install radios you need to copy the app using ESExplorer or Root Explorer straight to /system/app in place of MTCRadio.apk
      Radio version 4.2.2 800x480
      Radio version 4.4.4 800x480

      Radio version 4.4.4 (Malaysk v1, aka alive)

      [*]Car Service. Allows to use SWC and buttons with 3rd party apps (Latest Malysk ROMs already include it).
      Download here (thanx @@KeiserSozeyFr)
      If it does not install, copy directly to /system/app

      [*]Microntek HeadUnit Service Latest Malaysk ROMs include it. It allows to use SWC with non native apps. It allows to make calls and send messages from Android part of HU, and to show toasts. You can find it straight on Google Play.
      There is a modified version (probably outdated) with early start of services here

      [*]Moded Music app. Two versions. One is the original with expanded list, so full names can be seen, and the other one has the list integrated in the background so it is always visible.

      [*]Set Loud Latest ROMs do no need it.
      Method 1:Method 2:

      am broadcast -a com.microntek.irkeyDown --ei keyCode 44

    Good news for Sygic users :)

    I have found solution how to make Sygic to work on ours devices.
    It is wery easy and it finaly works for me, and I would like to share it with others. You can make it in two steps.
    First of all you have to install rooted ROM. I have install update_4_4_4_RK3066_1024X600_7_MAL_14_05_2015.rar
    You can find rooted rom for your device on this link https://drive.google.com/folderview?id=0BxmzvLRI7-eNeVA2SWkwM1pLZ28&usp=sharing#listv
    When you done you have to install Xposed IMEI Changer. You can find it at Google Play Store and start the app. Xposed Installer will prompt up and you have to give permissions to IMEI Changer and to install Framework if you did not already.
    Than yo have to open IMEI changer and copy IMEI code from your smartphone. (I have HTC M7 and IMEI code you can find in Settings-Info-Tlefon identity.
    After that you have to reboot device and open IMEI changer to see is it new IMEI applied.
    If it is, than you have to go to Google Play Store, install Sygic and download maps.
    Result you can see on attached image.

    I hope that it will work for others.

    NEW from 27 October, 2015
    Only for RK3066 800X480

    Most global firmware update from me, perhaps a few months to 800X480.
    Changes, updates, deletes, transfers, etc. lots of. I write about everything I will not. Here are just a couple:
    +++ Android part of 10 October.
    +++ New NEXT launcher - a slightly redesigned our radio me :)
    +++ The new boot logo (the very first - that appears when you download a few seconds)
    +++ Added gradient Status Bar (Settings - System)
    +++ A new panel ext. programs and recently run (Settings - System)
    +++ Added new tab in Preferences - Advanced Settings screen (think there will understand)
    +++ Fixed program MTCBlueTooth - incorrectly displays the number of the incoming call
    +++ Well, and so on. D.

    Firmware I have not done a simple upgrade - erased all the data. Make a backup of your applications (System Settings then do by hand - not to restore from backup !!!)
