Hello. I have recently bought an Android HU from Aliexpress. MCU version says: 2018.05.29 18:59:52 KET_[R76DK3]__26_C26D_STM32_CAN(All)_AMP

I have talked to the seller who claims this is an MTCE unit. Would this mean it should be compatible with the Hal9k ROM in this thread? Sorry if it is a stupid question but I can't find any info on my HU anywhere.
[MTCD Software Development] marchnz:
Not an MTCD unit.

I have two phones added OK, though, can't add ODB, tried no brand ODB as well as Kiwi 3 LE OBD

---------- Post added at 03:00 PM ---------- Previous post was at 02:57 PM ----------

do I use the same bt app like for the phone ? or it there another app ?

I don't seem to be able to add neither no brand BT OBD, nor Kiwi3 LE BT OBD..?
[MTCD Software Development] franky88:
This is my devices features. Can ı install this rom on my devices ? Or ıt is Same?
[MTCD Software Development] Toto1365:
yes you can install the Hal9k Rom.
[MTCD Software Development] franky88:
After install , does my Bluetooth work properly ?
[MTCD Software Development] Toto1365:
you have to look in the factory settings, which Bluetooth module is installed.
[MTCD Software Development] le_mi:
Yes you can install this rom (px5, mtce). It's oreo too but with more and better features in the settings.

I've been trying out android 9 build and considering reverting to Android 8 3.1.2 version of ROM.

I f I do revert do I have to revert recovery or can recovery 9 install the Android 8 image ? (I suspect yes but just want to be sure)

I'll push a review when I've made my mind up on whether to revert or not.

[MTCD Software Development] movieifx:
So my review of Android 9 based on comparison of previously using 3/3.11/3.1.2 version of Rom. I hope this is useful.

My unit is MTCD PX5 4GB/32GB with GS firmware. (Badged as Xtrons).

Upgraded with no problems or complications.

Pros

Can't honestly say that in terms of responsiveness that I notice any difference. Possibly slightly quicker moving between apps.

I don't use stock launchers as I'm a fan of CarWebGuru and I confirm that works fine here.

DAB-Z Noticed some stuttering when running in background and running other apps e.g. file explorers

As stock rom it meant I wen back to MTCDTools to map buttons/keys as required. The only thing which this doesn't address is editing the MODE button to cycle apps)

Jetaudio plus did seem notably faster at the initially location of my albums (there are over 1000 on the external sd card)

Camera DVR recording to App on GPS card slot was fine with no camera glitches.

Bluetooth calls connected to phone ok though I have experienced some loss of bluetooth connection after making a call (but not always). But see MTCD Dailer issues below.

Connect to ODBII bluetooth device and Torque working ok.

The soundmod MCU with modified amplifier app works fine. (But I miss combing this with ViperAudio)

Issues

Can't get MTCDDailer working. Launching it manually, it always claims it can't find the matching contact. Connecting to Google/Google assistant despite being set to the correct app for calls, it doesn't launch it. I'm using the version that was tweaked for Android 8, maybe a tweak for A9 is needed ?

Google contacts is not syncing (refuses to acknowledge my google account and then claims it's already setup - had this previously with stock but the 3.1.2 ROM didn't have this issue)

I had one instance where the device came on from standby but refused to connect to any usb devices (DAB and usb memory stick). But this has only happened once so far. A reboot solved it.

It does pick up time from GPS network, but I have to use an incorrect GMT UTC offset to get the correct actual time.

What I miss most from the great 3.1.2 ROM

Application control and specifically white list and avoiding clashes between audio apps.

Working combination of google assistant/mtcdialer for making calls.

Lock screen security

Root

Viper

Questions

On the question of root. I have seen a comment that root via adb wifi works. Is this using same version of supersu as used on Android 8. Maybe if I could root and install apps from Titanium backup with data, it might get mtcd dialer working.

Way forward

After going on a short drive, system became unstable and crashed/rebooted several times. Have re-installed Android 8 3.1.2 which is solid.
[MTCD Software Development] le_mi:
If I remind correctly the android 9 version which is provided by Hal9k is a stock version. But I think and hope there will come a customs version soon. :fingers-crossed:
[MTCD Software Development] amxandy:
If you reinstall the 3.0 vesion of this ROM, your bluetooth will work. I have not had any luck getting most of my bluetooth OBD adapters to work with the 3.1 and up versions of this ROM. Try it and let me know.
[MTCD Software Development] TT_Vert:
Can you refresh my memory, I believe that you have a custom recovery we had to flash when we install your ROM? Ever since then I've not been able to manually get into recovery. If I have adb access I can manually boot to recovery but not w/ a sequence of keys. You probably cannot answer this but does anyone have this unit that can tell me how they get into recovery w/ button sequences?

Seicane with Android 9 dead after installing ModInstaller & Factory Reset

Today on my birthday... my birthday present a brand new Seicane 10.1" for Jeep Wrangler with the newest Android 9.0, is mostly dead after installing "ModInstaller" and after an attempt Factory Reset.

Here what I did:

1. Installed ModInstaller from thread: [ROM][PX5][Oreo][8.0.0] Hal9k ROM 3 for MTCD/E head units with Android 8/6

2. System rebooted on recovery mode but I had no keyboard grabbed a keyboard and rebooted the system this time no Recovery Menu

3. Uninstalled "ModInstaller" and reinstalled it, again no reboot (it will count down but then nothing happened)

4. On the settings I initiated a Factory Reset in the same way I did previously several times but this time did not work

Now if I press and hold the reset button after 10-15sec the Soft Touch buttons blink few times and a very dim screen backlight barely lights up the screen but NO logo no nothing at that point I can only press the reset button and the screen turns completely black re press the reset button and the dim backlight turns on for very long time.

I tried all combinations with the reset button (1 long time 2 short time etc.) I disconnected from power reconnected while pushing the reset button NOTHING!

my MCU version: MTCE_HF_V3.07_1 (Mar 6 2019)

Anyone with ideas how to get to the Recovery Screen at this point?
[MTCD Software Development] scorillo_ro:
Yes. In Android 9 the chinese made some changes to bluetooth.

Thanks is there Stock rom for my device ? İf there is can ı take link ?
[MTCD Software Development] abbots:
I'm not sure how to reinstall 3.0 - do I need full reset/flash of full ROM, or, is there a shorter way to revert to 3.0?
[MTCD Software Development] amxandy:
Just download the 3.0 update and then do the first OTA. Turn off system updates after that and enjoy your OBD device! No need to reset anything.
[MTCD Software Development] abbots:
Amen, dumb question, can I do it all on the HU?

or do I d/l on PC, then, copy file to HU, update?
[MTCD Software Development] amxandy:
Put the 3.0 update.zip on a usb stick and update from there. You can take the first OTA after that, should be a small file. I then turn off system update notifications and can use all of my ODB adapters after that.

Disable Last Running App on Start

Hello Gentlemen,

Hal9k thanks for the great ROM. I am the new owner of an xtrons octacore 8.0 4gb ram/32gb head unit now running you rom with MTCE_GS_V3.00_3. Everything is working great except I am really hoping to find a way to DISABLE the opening of the last running app on start. I have dug through everything I can with no luck. I did a bunch of digging around on the forums and the only thing I could find was MyMTCService app that actually does have the option to disable last running app launch, buttttt it's not working for me. (I installed xposed framework that mymtcservice uses and rebooted the thing about a thousand times, couldnt get it to function)

So, does any one know of any way to DISABLE the launch of the last running app on start up that I am not finding? Thanks you!

maybe ask your vendor to show you how to remove it
[MTCD Software Development] spookie79:
Why not wait, until a customer ROM with v9 is available? Why is it so important to have Android 9 now?

I would say it makes more sense to wait and not to have the really latest version. When I see how good the ROM here works with the system in the car of my wife, much better then original ROM, then somebody could say the old sentence: never change a running system. Or wait until a custom ROMS exists.

You can wait, but there will be NO OFFICIAL 9.0 for old units from vendors!

Dasaita answer, when i asked about it:

our device only update in the same system , can not upgrade to android 9.0

Do you buy 8.0 unit - you have 8.0 updates officially!

it probably requires the android 9 recovery, meaning it has to be installed on top (or instead) of the version posted by [MENTION=5092263]Hal9k_[/MENTION]

No, Headset doesn’t work with speakers attached to HU, only Speaker settings. On a phone with a headset connected it will of course work. Read somewhere that it was possible in earlier versions of V4A to lock the output to Headset settings even with speakers connected, but not anymore.

What is the preferred way to do automatic backlight brightness control based on time? Running the latest Hal9k, I am always having to manually adjust the brightness. Malysk rom had a built in GPS-time controlled app that worked pretty well, except for when it didn't want to launch on some resumes.

Application sleep/wake management doesn't seem to work well. I have white-listed a few apps to not be killed upon standby. 2/5 times, Spotify will resume back to where I was and auto resume the song that was playing before shutting off the ignition. Other times, spotify is completely killed and I have to go reload it.
[MTCD Software Development] le_mi:
Try this app. It's the same as in malaysk rom. It adjust the brightness by GPS based sunset and sunrise.

I recently started having issues. I'm running 3.0 (never did an OTA upgrade). All was working perfectly, and all does for about the first 2 minutes after starting. Then my volume buttons on the radio (or SWC) no longer display the slider (though the beeping can be heard when pressing them) and there is no change in volume. My home button stops working. The reverse camera input stops working (the display will blink to black then immediately return to radio when shifting to/from reverse, though). The power button held will bring up the "restart, recovery, safe" options, but selecting them does nothing.

As stated, after a reboot, everything works for a minute or two, then the symptoms return. It's almost as though there is another process/app/mod that is taking over these functions.

Do these symptoms sound familiar to anyone? I really want to avoid rebuilding the HU if I can.

Also, in terms of upgrading to the latest version, is there a downloadable package (from PC) that has the latest, or do I have to do the OTA? My internet is horribly unreliable and terribly slow - and the OTA fails before it completes.
[MTCD Software Development] amxandy:
Everything is on the first page. At this point, a clean install will clean up most of your issues.
[MTCD Software Development] erkme73:
That's what I figured would be the case. But, in retrospect, the one thing that I did change recently was removing my BT OBDII adapter. My other vehicle's check-engine light came on, and to quickly diagnose it, I pulled the adapter from my daily driver and never put it back. While the HU didn't throw any errors due to the lacking OBDI adapter, I just now reinstalled and rebooted the HU. An hour into it, and everything is still working.

I suppose it could be coincidence, but I'll take lucky over good at the point. If the problem returns, I'll go ahead and rebuild.
