[MTCB Android Head Units Q&A] MasterPrenium:
Hello guys,

I'm using a new KGL-8401 with 1024x600 screen resolution, running on 4.4.2

I would like to have a rom fullyu unlocked, so with root access and with custom hardware keys. Which one should I use ? I saw that some KLD are rooted for 1024x600 screen but are they fully compatible with my KGL device ?

Thanks for any answer, I'm currently quite a newbie with this unit but want to learn a lot :cowboy:.

[MTCB Android Head Units Q&A] typos1:
I should start reading the thread then, at least from 2 weeks ago onwards - a KGL with KK from the factory has fully working bluetooth, but we cannot get root.

KLD and KGL KK updates result in bluetooth that does not work with OBD and one report of it not working at all.

So I would wait and til we get root on factory KK.

What does it say for the mcu in the about screen?

That is the mcu you need.
[MTCB Android Head Units Q&A] typos1:
Do a thread search.

Plenty of info, theres a few options, but Ive already typed them out several times, dont really wanna type em out again !

But if youre in the UK at least, DAB is rubbish - its been replaced with DAB+ in the rest of the world and we cram so many stations onto each multiplex that bandwidth is ridiculously small, so FM gives substantially better kb per sec and superior sound quality.

Youre better off streaming really, that gives an equivalent sound quality (ie still pretty poor) but with much less hassle - just tether your phone/use a 3G modem and an app.

Fastboot doesn't seem to see the device. I think I'm going to uninstall drivers and start over. The device shows up under ADB devices in Windows Device manager, but ADB/Fastboot don't see it. When i do Fastboot reboot, it says waiting for device but nothing happens.

The lights do not come on at all, even when pressing the reset button. When I press the reset button windows makes the noise that the device is disconnected then reconnected when I let go of it.

I didn't flash anything at this point. I was only trying to get into bootloader to make sure I could get there. Hopefully its a driver issue in windows and not something wrong with the unit....

Another update on my Bluetooth not working. It seems as though the bluetooth adapter isn't recognized or it quit working entirely.

It's strange that the whole bluetooth setting are greyed out and force close if you try to select anything.

Flashing different roms/MCU's hasn't helped me yet, but I'll play with it some more tomorrow and see if rolling way back will solve anything.

I'm at a loss here. I tried a few different drivers (clean installs each time) and have had no luck actually using fastboot/adb. The computer can see the device (so can't some of the RK programs) but fastboot/adb don't. I went to a friends house who has a mac, since drivers aren't needed for that system, and still no luck sending commands over fastboot/adb. Both systems see the radio but can't talk to it. I emailed the manufacturer to see if they can help. Looks like its back to the OEM headunit for now...:mad:

Flashing back to 4.2 will will solve everything - BT OBD worked in 4.2. why dont you try modifying 4.4 so it has the same BT set up as 4.2 ?

I use Linux, so I dont need drivers either, so cant re-install them as zorantoma suggested. Why dont you contact your supplier and get a replacement ts12345 ?

[MTCB Android Head Units Q&A] kwalsh24:
I'm using apex, like it over stock ... gives the option for bottom or side dock, but also like how titanium backup will restore the launcher and all its settings, so im not javing tto redo all my windows / desktops when I flash firmwares.
[MTCB Android Head Units Q&A] typos1:
I use Nova on my phone, there are loads of settings, including for the dock and where to put it.

For the KLD launcher you can put it into the system/app folder replacing the KGL one, if youve got a copy of the KLD launcher, that is.

I m gonna flash the KGL later, I ll copy the KLD launcher and upload it if you like, save you going back to KLD 4.4 and doing it yourself, then flashing KGL 4.4 again.

Are these KGL 4.4 images without recovery, do TWRP or std recovery have to be installed separately ?

KGL-8401 - 1024x600 (VW version).

So as you say, the steering wheel keys are interpreted by the MCU ? Couldn't we modify the key code directly in it ? As I saw on CarProg, the keycode 45 & 46 are just reverted for those keys :confused:
[MTCB Android Head Units Q&A] ktibor69:
I have JY HU (Ford Mondeo). I have same problem: keycode 45 & 46 are reverted when I use MTC apps.

I got this information in this topic:

"The "Steering wheel key menu " (on your screenshot) is only to define the buttons when your car don't have CAN-BUS.

I think there is something wrong about you MCU configuration. There is a configuration file on the HU to redefine the buttons."

Do you have canbus box?
[MTCB Android Head Units Q&A] coudu:
could you please help me find the right version?

use a root explorer to delete /system/priv-app/PrebuiltGmsCore.apk and /system/lib/libAppDataSearch.so, /system/lib/libconscrypt_gmscore_jni.so, /system/lib/libgames_rtmp_jni.so, /system/lib/libgcastv2_base.so, /system/lib/libgcastv2_support.so, /system/lib/libgmscore.so, /system/lib/libgms-ocrclient.so, /system/lib/libjgcastservice.so and /system/lib/libWhisper.so

then install THIS ONE as a normal apk

It will then either prompt you to update or silently update with the right version.

then go to settings -> applications -> all -> Google Play Services and tell me which version you have e.g 6.1.88 (1557022-0XX) I need the two last digits.

[MTCB Android Head Units Q&A] MasterPrenium:
Same for me, I can confirm !
[MTCB Android Head Units Q&A] coudu:
6.1.88 (1557022-030) is the universal "nodpi" version, it may be the one required on 1024x600 devices because of the weird dpi setting (300).

But just to be sure can one of you visit com.google.android.gms from his device to see if google play asks for an update with a "fixed dpi".

[MTCB Android Head Units Q&A] agentdr8:
Yep, that should be possible. I'm guessing you'd want it max bright even if reversing at night time?

Also, keep in mind that this would only apply when MTCBackView is loaded, and not when the MCU is handling the reverse camera (before Android loads).

ok thanks, I'll include the 030 universal version in the 1024x600 images.

you'd better use market helper if you wanted apps that doesn't show in market rather than editing build.prop's fingerprint which can cause other problems with some apps.

[MTCB Android Head Units Q&A] webdude12:
As my time seems to get more and more limited and I figured out a way to flash recovery only fairly easily from the bootloader and adb. Can you whip a 1024 x 600 TWRP that fits the original 4.4.2 Partition schema instead of the modified one? That way I can get attempt to do a system dump of a factory installed system, with the fully working Bluetooth. :)
[MTCB Android Head Units Q&A] coudu:
New 4.4.2 partition schema is about the order of the parts in the nand which is different from 4.2.2, not their sizes so this works on both original 4.4.2 and custom ones.

please make sure you can backup and reflash your original recovery if anything goes wrong because this 1024x600 image is untested but there should be no problem as this is just the same as the 800x640 but with a 1024x600 kernel.

using twrp you'll also be able to root your device ;)

[MTCB Android Head Units Q&A] webdude12:
Cool, I havent research 4.4 that much. I just knew on 4.2 you had to define the exact location of each partition by block size.

The way I am going to flash relies on bootloader, not recovery, so hopefully this works and then I can pull the factory restore image, which includes recovery image.

Hopefully I will have a dump soon. :)
[MTCB Android Head Units Q&A] MasterPrenium:
Hey guys, great news ! I fixed it. At least it should work on newer VW/Audi/Skoda/Seat cars.

You have to go to the settings menu with password 126, by default you should have selected 1)VW/Skoda Canbus (simple), si fix the next & previous button reverted, you need to change it to Golf 7 Canbus (simple).

I think it won't work on other car brands, maybe only on a few one. Otherwise we will need to fix it in the APK that manage the Canbus.

[MENTION=853627]coudu[/MENTION] : I've just saw you released a 3.1 version for 1024x600 ? Is it the fix for the market ?

Maybe it's me who have done something wrong, but is it normal that I have the old music player (like on android 2.x) ? (it turns automatically on when I use the next hardware key with CarService, I didn't have this annoying comportment while using other "roms").

I'm fairly certain that my Bluetooth issue is a hardware one. Downgrading to 4.2.2. didn't help, nor did changing MCU's.

Anybody ever had one of these taken apart? Is it feasible to change the bluetooth adapter or am I better off to send this thing back to China (for the second time) and spend another $60 for shipping.

Anybody have a contact for the Klyde Manufacturer to get a new bluetooth board?

[MTCB Android Head Units Q&A] agentdr8:
That error is fine and can be ignored I believe. The BT OBD not working in KK is a known issue, and most likely will be resolved with a different image base (maybe the one webdude pulls).

Dalvik is default, but if you enable the Developer settings, the option for ART is there. I haven't tried it yet, and won't, because the Xposed Framework only works with dalvik.

---------- Post added at 10:15 AM ---------- Previous post was at 10:10 AM ----------

If you're handy with a soldering iron, then it shouldn't pose a problem. The BC6 is a through-hole mounted board that's perpendicular to the mainboard.

I would verify that you have the proper bluetooth option selected in the Factory Settings screen. If you pick an adapter that isn't present, it causes all sorts of issues with BT-related apps.
