AFAIK, the different Android audio streams (ringtone/notification, alarm, media) have been combined into a single one on these headunits. Instead of raising the volume of TTS, you could lower the volume of music if the media app you're using supports this (PowerAmp has an option to mute when other apps try to output sound). Or you could edit the audio setting for SYS under Factory Settings to make all Android sounds louder (and thus TTS), and then lower the sound of music within whatever media app (again, PA's EQ has controls for its main volume).

Ok - nothing works again, no 3G - and OBD connects via Bluetooth, but not in Torque. I'm going back to 4.2.2., anything greater than that seems to have constant issues.

Can anyone recommend an update which has decent gui similiar to 4.4.4? I'd like to be able to change the icons on the bottom bar. I don't use things like radio and video.

Hello!

I must say that it is not safe/responsible to say to update the mcu if it can cause problems for example your hard keys as said.

At least there should be the way to dump yourold mcu.

It is good to know that bricking should not happen when using same manufacturer version.

Does somebody have KGL-V201 versions.

Or where are the newer 2.09+ kgl versions?

-Jukka
[MTCB Android Head Units Q&A] Karanso:
Have everyone KLD mcu 2.02 file?
[MTCB Android Head Units Q&A] ultradj83:
Well, I perfectly know the theory, anyway I made clear that it's not always possible to downgrade.

Since I installed KGL2.09 I can no more revert to versions before 2.03, so I was suggesting you to find a way to backup your stock MCU, if possible.

My device is ES9610A, this should be the universal version of yours.

Now, what 4.4.4 firmware are you running on?

Have you been taking some time to check Spotify and ES Explorer run without problem, Bluetooth OBD writing with Torque and overall 3G connecting without problem on any boot?

Thanks a lot

Dears,

any rooted 4.4.4 reported not to suffer 3G/Wi-Fi problems, Spotify/ES proverbs, Bluetooth OBD problems and Radio presets problems?

Thanks!

NO ONE has had any problems changing their MCU to one of the correct manufacturer. Why are you so obsessed about 2.01 ? Have you tried EVERY other KGL MCU ?

Hey guys

i just installed on my klyde new fw:

KLD2_KK_800x480_14110_rooted_light_3gb-internal-memory-mod

I went into playstore and installed all the apps under my account but for some reason my paid app are telling me to pay again and when i do play it says payment declined?

What could the problem be?
[MTCB Android Head Units Q&A] typos1:
I ve not heard of any one not being able to change their MCU version before. If the unit does not automatically find the MCU.image file on the GPS SD card, have you tried booting to recovery and installing from there ?

ES file explorer works fine on my version, dont use Spotify and use USB for OBD as its faster and more secure, but 4.4.4 has been reported to work with BT OBD, fixing the problems with BT OBD in 4.4.2.
[MTCB Android Head Units Q&A] ultradj83:
Well, it is the recovery to fail reverting to elder MCUs. It fails the mcu update and after reboot I see version is not changed.

Actually the only mcu related problem for me is back button acts as gps button.

More critical is 3G, it's a disaster, it rarely succeeds connecting.

Are you encountering the same problem?

What firmware are you exactly running?

Thanks.
[MTCB Android Head Units Q&A] lormeau:
3G only worked once for me since the kitkat upgrade. Very frustrating. Can't seem to narrow down the root cause of this problem. Will try other update,img and see if problem goes away.

[MTCB Android Head Units Q&A] kvantum:
I posted a repository with every single version, including 2.01 and everything above and below

You replied to that message so clearly you saw it

There is no way to dump your existing MCU. Just check which version you have and match it to the repository version. It is literally the same thing.
[MTCB Android Head Units Q&A] mikochu:
I've been content with coudu's v3 KitKat 4.4.2. However, if you use Torque, BT OBD won't work in 4.4.2...and USB OBD+Torque can get annoying. If you have your USB OBD plugged into the head unit at bootup, it auto-loads Torque and doesn't allow the system to fully boot up, meaning the touch screen doesn't initialize. No offense to those who help out in this thread, but I'm a bit perturbed to read "just get a USB OBD adapter, it works great and is faster" to find it has it's own issues right at bootup.

I was just about to upgrade to v4.1 KitKat 4.4.4, but it seems people are having issues with mobile internet dongles.
[MTCB Android Head Units Q&A] RyanBRZ:
There are no working Roms that allow USB obd cable to be connected during boot?
[MTCB Android Head Units Q&A] agentdr8:
It would be:

am broadcast -a android.intent.action.BOOT_COMPLETED com.keisersozey.carservice

It's an issue with the Google Play Services. This has been resolved in coudu's v4.1 version.
[MTCB Android Head Units Q&A] bobojan:
Why not use the wifi obd it is working great and always did with torque
[MTCB Android Head Units Q&A] agentdr8:
I would say it's this particular manufacturer's version of 4.4.4 that's the problem. I've got 4.4.4 running on various other devices and those have no issues with apps that receive the BOOT_COMPLETED intent.
[MTCB Android Head Units Q&A] Boodro1:
can we get a copy here?
[MTCB Android Head Units Q&A] ultradj83:
Well the 3G problem makes the unit 75% useless...

Anybody installed official 4.4.4?

Are the 3G problem and radio stations saving problems confirmed on official versions?
[MTCB Android Head Units Q&A] bobojan:
Hi Boodro1 you can download it from here https://drive.google.com/folderview...haring&tid=0BxmzvLRI7-eNeVA2SWkwM1pLZ28#listv

But I don't know what the new stuff in 2.20
[MTCB Android Head Units Q&A] mikochu:
They all do, I believe. The problem is that Torque automatically opens when it sees the USB OBD cable. At bootup, that interrupts the boot sequence and the touch screen initialization never happens. You either have to plug in a USB mouse to reboot the system, or do a physical reset. On the Torque forum, there has been a few requests to have that auto-open function on a toggle.
[MTCB Android Head Units Q&A] typos1:
Well I never had this problem on 4.2.2 and I ve only heard of 1 other person with it and I think that was on 4.4+ so maybe its related to KK ? - I havent used Torque on KK yet as my unit is out of the car, a possible solution is to use the Torque OBD Toggle widget ?
[MTCB Android Head Units Q&A] RyanBRZ:
So based on my question and your response, no ROMs 'work'. 'Work' meaning proper functionality.

I'll be installing my unit in a few days which is klyde / 4.2.2, I'll report back how it works.
[MTCB Android Head Units Q&A] Boodro1:
I have terrible luck and don't want to be the first to try it. haha

Has any tried it yet? Anything change from 2.08?
[MTCB Android Head Units Q&A] bobojan:
Well same here :), that's why I wrote
[MTCB Android Head Units Q&A] mikochu:
Torque OBD Toggle Widget? Didn't know that existed. I'll try it out.

Edit: I purchased the Toggle Widgets and it mysteriously started to work as desired. However, I disabled the widgets and everything was still a-okay. I think the last Torque update (a few days old) fixed the issue, but wasn't in the change log.

I think it's Torque-related, not ROM-related.

Edit: It doesn't seem like it's an issue anymore. Which cable did you get? The OBDLink SX cable works well.

Services have to be specified in the AndroidManifest.xml, but they aren't started automatically at boot. The supported way of starting services at boot time is to request the RECEIVE_BOOT_COMPLETED permission, and register a receiver for the BOOT_COMPLETED intent.

Starting a service directly with am startservice may or may not work, depending on what other things are done to prepare that service for starting (usually found in the BOOT_COMPLETED receiver code).

Make sure you check the box for hotspot compatibility, and also make sure on the headunit, you designate it as the Tablet. You'll also want to set the password the same on both units.

The OS uses the Package Manager to determine which apps have services. Not all of them are exposed to other applications (private services), and they don't inherently start until told to start (usually via Intent).

The priority for the broadcast receiver in CarService can be changed by [MENTION=5867075]KeiserSozeyFr[/MENTION], but I don't think making it higher will get it starting sooner (I changed both XposedMTC's and PowerampToast to 99 and it still starts a while after the last foreground app).

You download the Coudu firmware and put it in a formatted sd card then you put it in gps slot if it reads that there is a new firmware then you confirm if not then you have to push volume button and the reset with a small pin together in 5 sec then you release the reset button on keep holding the volume button until it goes in boot mode then you choose firmware update and keep pressing the volume button on it.
