You definitely need to hack the TV box firmware. The menu is "on screen menu" type, i.e. is created my the TV box itself as overlay onto the tv picture.

Please don't mind a very general question.

I was on business trip for a couple of days and returning I find another ~ 15 pages of posts.

It's very hard to follow a specific post, i.e. just reading one post after another.

So my question: Is it possible to follow a specific post just as a sequence of its replies?

THANKS!

Is there anyone who can provide V2.0x 'KGL' firmware [KGL without a number]?

My re-seller can only provide 'KGL4' to me, but this destroys my keys [buttonless HU] - maybe he also downloded himself somewhere.

Looking at the internet I just found repositories containing 'KGL4' builds.

Thanks!

No problem at all, I am glad if I was any help :)

I have a Golf MK6, I was on first FW and 1.70 MCU. Everything was working, but I wanted to fix Wifi problem and have dual can-bus. Last couple days I have 3G modem it is working good but sometimes connection fails out of sudden and I have to reconnect the 3G modem or reboot the HU so that was one more reason to do a update.

Can-bus is working better now with FW 2.02 but only from HU to car and not otherway around, but I still don’t see open door warning on the HU that’s probably fixed in the MCU.

I don’t understand why the MCU image won’t work, it can’t load the config file and then it says image is not found, really weird.

I am going to try 1.99 MCU and Update see what happens. But the thing is if it works I am afraid I can’t go to MCU 1.77 since it won’t flash.

I've read every single post in this thread, but it's been a while so this may already be posted. Sometimes I check the other active thread that's in Russian and thought I'd share the Google Drive link they posted with all the firmware. Can't guarantee it yet, and haven't installed any myself, but maybe this will help some folks out.

Thanks ProfessorKnox :) There is no need for that anymore :(

I am done with it, it is not possible to update my MCU on this unit no matter what I do, just came back from the car tried every MCU and FW combo and same date releases and still no go, at the end I installed 2.02 FW and I am still on 1.70 MCU, recovered everything back with Titanium rooted and installed exposed and that’s it.

I have every try same error:

Like it is getting blocked by something since the cfg gets aborted, I would appreciate any help with this.

Hi Reptile, just a stupid question: are you using the GPS sd slot? I sent my MCU177 file with this message, maybe something wrong with yours?
[MTCB Android Head Units Q&A] agentdr8:
I've updated XposedMTC for non-SWC users. There are 3 new launcher icons that will get added after upgrade; MyMusic, MyVideos, and MyRadio. Use these shortcuts instead of the original ones for your preferred music, video and radio apps. These launchers will use the apps selected as your preferred apps within the XposedMTC settings and resolve the audio switching issues when you go between Radio and Music or Video using icons instead of a mode switch button (for those of us w/o SWC).
[MTCB Android Head Units Q&A] Reptile-X:
Hi ev1966, I got the MCU files from File reporsity and from first page, I did try every MCU available still same problem, I am not sure but not all of those would be corrupted right? I downloaded several times and checked and it didn't work.

I will try yours too. I couldn't use GPS SD slot because it wouldn't see the updates there so I copied the files to internal "SDCARD" folder, and all FW updates worked from there too.

A side note, I couldn't get in to Recovery either with any key combo, so I was using Quick boot or reboot the device so it picked up the updates itself. Maybe something is different on my HU?

Are music files and navigation software readable from the GPS slot? Strange the update files don't work from this slot.

A reboot is the way for me too, to acces the update files. I haven't tried other ways to acces the update files.

As you say probably my file won't work either, but it is worth the try
[MTCB Android Head Units Q&A] Reptile-X:
GPS slot works, Tomtom is working from there, also when I need to side load the apps I use that card slot too. I have XDA Premium app so tomorrow I will download your file directly from the HU without any SD card or USB stick, maybe my computer is f*ing them up. I highly doubt it, but you never know. :rolleyes:

The radio stations sometimes randomly reset back to default. Does anyone know why this happens? Any way to stop this from happening?

i9500 CM11 Nightly

KGL8102 v2.02
[MTCB Android Head Units Q&A] agentdr8:
When the RadioService loads, it reads the system preference file looking for a first-time bootup scenario:

private void loadPreference()
{
resetFlag = false;
int i = android.provider.Settings.System.getInt(getContentResolver(), "microntek.firstboot", 128);
if ((i & 0x81) != 129)
{
resetFlag = true;
android.provider.Settings.System.putInt(getContentResolver(), "microntek.firstboot", i | 1);
}

If for some reason the resetFlag gets set to true, then the defaults get written back to the prefs file. As you can see, the default value of the microntek.firstboot key is 128, and when bitwise ANDed with 0x81 it equals 128 (decimal), which falls through and resets the key to 128 OR'd with 1, which is 129.

I can fix this with XposedMTC, by setting microntek.firstboot to 129 at every boot. Then it would never get reset.
[MTCB Android Head Units Q&A] idr3s:
Don't understand the coding bit as much, but I see what you mean..

Would definitely be helpful if you'd update that in xposedmtc =)

Hmm upgrade to 14.3.1 now appears xposed / appsettings isn't working again to change the dpi....

Went back to 13.4.1 and its working again. So something in 14.3.1 must be blocking the dpi adjustment. I have mine set to 296 and its working quite well, minus a minor crashing issue when the system asks if id like to avoid toll routes, ill just manually turn that on and off to prevent the message to appear.

Must say tho, still prefer Igo still, I just find with sygic that it doesn't warn long enough ahead forvwhen you need to exit a busy highway, Igo for examples gives you 1km before you need to exit, sometimes sygic gives you a warming at 250feet. Semi annoying.

Headrest Monitor

Hi all;

Any ideas why the Huifei works with headrest monitors only on dvd but not with other 3rd party video players?

Is it related with MCU?

Is this a software or hardware issue?

Is there a way around the issue?

Thanks in advance
[MTCB Android Head Units Q&A] ProfessorKnox:
(1) Did you try just inserting the SD-card into GPS slot when the HU is running? This always worked fine for me thus I never tried any other update procedure than this. But maybe V1.70 doesn't support GPS-slot updates yet. To be honest V1.77 was the earliest build I ever read about in this thread until I read that you are running V1.70.

(2) Getting into recovery is indeed a little bit tricky and I had to try a couple of times.

- Ignition key removed, ignition off for ~5 minutes

- Insert ignition key (and have steering wheel in a position so that ingition key can be turned easiliy)

- Press reset and on/off button

- Wait a couple of seconds (I did wait ~10 seconds)

- Turn on ignition while still reset and on/off buttons are pressed (here you need some acrobatic capabilities ;) )

- Keep reset and on/off button pressed (be patient, I had to wait a certain time, maybe 20 seconds or so?) until

- - either recovery mode appears -> success :)

- - or radio starts up normally -> process failed :( -> start over again with ignition off, ignition key removed and ignition off for ~5 mins.

Hope this helps
[MTCB Android Head Units Q&A] clu26:
Thanks man that worked, althought now I noticed (since it's night) that the backlight is always on, even If my lights are off, anyway it worked thanks
[MTCB Android Head Units Q&A] Reptile-X:
Hi ProfessorKnox, Thanks for heads up and time you put in writing :)

Yes I did unmount and mount the GPS SD slot when the HU was running and didn’t do the trick unfortunately.

I did try your second suggestion too, since our cars has long acc 12+ I thought I wait a while and try both buttons and turn on the ignition, my son was helping with the buttons, I am probably not so acrobatic as you are :D But I found out that Quick Boot app working really nice to get in recovery.

I was almost 14 hours busy with this in 2 days, I even took my laptop to the car so I could download the needed files on the run and try them. I tried every possible combination I can think of with the FW’s and buttons :eek:

Like you said maybe my MCU being 1.70 is the problem, I installed the HU in may but ordered long time before and received it in march. Maybe it was one of the first units made and it from old stock? :confused:
[MTCB Android Head Units Q&A] Reptile-X:
Hi ev1966, I just downloaded the mcu directly on HU and I get same error as before. Thanks for uploading and heads up :)

Hi guys,

my name is Markus and I live in Germany... My car is a BMW e46 (from 2003) and I've got a Erisin ES-9746 in july. Everything works fine so far, but now I need your help:

I installed Tomtom 1.3.2 for navigation, but when the radio-app is running, the volume of the tomtom-speech is very very low, so that I don't understand, where to go ;) But: when the radio-app is off, or when I listen music with poweramp, the volume of the speech is ok.

Installaled Software:

Huifei-firmware 2.02, MCU 1.77

Poweramp

Root

xposed framework

xposedMTC 1.2.4

torque

tomtom (of course ;))

Can you please tell me, where I can set the volume so that no matter which app plays music tomtom can be understood?

One little thing with xposedMTC / Firmware 2.02: Loudness-Setting will be saved (and restored on reboot) with this firmware - but now changes xposedMTC the setting at every boot (if activated in xposedMTC)

In den GPS Einstellungen kann man einstellen wie das Verhältnis der Lautstärke sein soll bei der Navigation.

You can configure it in the gps Options how loud the Navigation should be at listening to an other source.
[MTCB Android Head Units Q&A] maan2304:
The problem is: with the radio-app running is the volume too low, if the radio-app is NOT running / another app (poweramp) is running, the volume is ok...
[MTCB Android Head Units Q&A] george2350:
I have the same issue - with the following config

With Radio on - gps directions and alerts barely audible

With Poweramp - gps directions and alerts at good volume

Firmware version 1.93 KGL unit.
[MTCB Android Head Units Q&A] agentdr8:
Yeah, when I had anything set in App Settings for Sygic, it would crash.

Isn't the notification distance adjustable? I thought I saw a slider for that.

I tjougjt I did too, but all I seen is warning sliders for speed, sharp turns but nothing for exiting roadway, will have go double check
[MTCB Android Head Units Q&A] agentdr8:
Change the GPS mixing under Settings->GPS. You also have to use the nav app selected under Settings->GPS->GPS Application. It won't monitor for other apps to mix. I think a reboot is needed for the change to be effective.

If that doesn't resolve it, try modifying the Audio settings under Settings->Factory Settings->Audio and change the setting for SYS to a higher value. You may have to then lower the value of Poweramp's volume using the knob in the EQ.

Reading your post once more again, mcu.cfg being aborted shouldn't really be the problem.

radio bad reception

As you may know if you read our sales terms, the first owner has a two-years garantee on HUIFEI products , but not the subsequent owners

It is not logical. The garantee is of the equipment or the owner.

hey guy ,

i already found that link and this is the unique link that you know and that i found . this link not say that radio is good.

but if you search in youtub you saw a lot them with radio work bad at this model and similar models.

i ask you a question where buy a good amplifier inline for mercedes (fakra conetion) and you didnt answer.

i knew that ww need amplifier but when you sell you dont tell us that mercedes need amplifier.

, ...... to other people saw that you sell equipment that don't work at radio or work very bad (with the amplifier and the blue wire is conect to 12v remote amp) if the car is driving. when car is stop works well what it found.

Hey when you were trying to modify the mtc manager app did you try to reinstall it as a user app or copy it to the system folder?

I have noticed it only works in the system folder. Without or if it is in the user folder it you lose touch screen also, have to use a mouse. I am still searching the code to see what is before ir.keydown. There has to be something in this code as without the file I have a lock button, and and home, nothing else. It changes the lock button into a button that can call the mute somewheres in here. I have deleted all other mcu stuff except for one app.

I will see if it controls anything or just has settings in it after deleting the other file, I think the other app just does audio though.

Looks like something around line 1360, or maybe 2238 in the server file to me, but i am no expert.
[MTCB Android Head Units Q&A] Navall2:
I stand corrected. But it was not very obvious.

[MTCB Android Head Units Q&A] Reptile-X:
Finally I worked out how to update my MCU guys, like I said before my HU wouldn’t update from GPS card slot only way to update the FW was putting the update.img with mcu.img in the internal /mcn/sdcard but the “not found” error for mcu.img got me thinking since most guys here update from GPS card slot, I placed a system.img and mcu.img in the internal sdcard root and only one mcu.img in to GPS card slot to see if it grabbed it from there and that worked, probably somehow my unit is checking the MCU update in gps card slot and the FW update in the internal flash, maybe it will upgrade from anywhere now since the mcu is upgraded from 1.70 to 1.77

I am not going to try that after couple days of struggling with this crap :p

Thanks to those who were trying help me out, I really appreciate it :)
[MTCB Android Head Units Q&A] agentdr8:
You can't install the MTCManager. apk as a user app; it's a system app that uses the sharedUid of "system" (i.e. root).

There's a code section that deals with the serial communication between the MCU and the Manager app. This is how it determines what physical button relates to which android keycode. This is also why some MCU firmwares tend to mess up button assignments.

What are you trying to achieve with multi-user? Different button assignments per-user?

[MTCB Android Head Units Q&A] agentdr8:
No problem. I like giving back to the XDA community as much as I can.

Working on the next release which should allow users to set their own radio presets, which will then get applied on every boot. This should get rid of the issue where the presets reset to the default values when you have to hit the reset button or the radio prefs don't get saved for some reason.

That would be great indeed, losing the stations every time is annoying, I would love to see if the dimming worked with the headlight switch (one of your future plans) Timed one works nicely, unfortunately here in the Netherlands is the time for sun set and rise changes a lot in couple days, could it maybe work with sun rise and set information from internet?
