My friend that sounds promising and gives me a little hope. I don't have this version, could you upload it to Dropbox, Onedrive or anyother fileshare you would like please? It would be much appreciate and my last hope!!

These are the versions I have flashed so far:

From Chinese vendor I bought the screen:

new software 20180823

From AVINUSA:

AVINUSA.COM_BMW_EVO_Software_Update_02-07-2018

AVINUSA.COM_BMW_EVO_Software_Update_03-13-2018

AVINUSA.COM_BMW_EVO_Software_Update_04-10-2018

AVINUSA.COM_BMW_EVO_Software_Update_06-01-2018

AVINUSA.COM_BMW_EVO_Software_Update_08-22-2018

None worked for me, all these versions are pushing Google Play Services 12.8.74 and crashing my screen.

Sorry, I missed that you have Android 4.4.4 unit.

The software update I have is for Android 7.1 unit. Sorry, my bad.

Oki, thanks.

I found the upgrade file img for 7.1, I have updated my unit with it. But i could only find MCU for NBT and CIC, not for CCC. Anyone?
[Android Head-Units] kalinkamaen:
Please check beside the screen on both side, there should be 1 hole on both sides for sd cards. Its not easy to see.

Is the balck metal cover the heatspreader? I can remember Android 4.4 unit had heat problem.

Can you post more photos of PCB?

Is the motherboard design different than on photos posted by bimmerpost user?

If you do get it going please do let me know - where are you based? UK / EU or US? I have a bunch of firmware so let me know if you need any - including latest stable / stock 7.1 it was shipped out with.

This forum is so long. Has anyone found a solution to clock resetting issue or CarPlay USB prompt? My Gen2 unit for E70 forgets the time and forgets the USB checkbox for the CarPlay dongle, any time I let it sit turned off more than a few minutes. Is there a battery current/memory wire that I missed??

Can someone confirm if they can pair bluetooth devices in the Settings-> Bluetooth menu on the 2G 7.1 units? If so, what version firmware do you have?
[Android Head-Units] InZone01:
iPhone X paired successfully, but can't pair OBDII device - bought OBDII WiFi device for that.
[Android Head-Units] doublespaces:
iPhone X paired in the Music app or in the actual Android settings area? I want to pair an OBD device, but Bluetooth doesn't even turn on. What firmware version do you have?
[Android Head-Units] InZone01:
I paired the iPhone in the Bluetooth via main menu launcher. As far as I know you can't pair OBD device via Bluetooth, you have to use WiFi OBD for that. Mine shows OBD interface in Bluetooth menu but clicking it doesn't do anything.

Firmware 20180625 if I remember correctly. I will try to update the unit to 20180801 and then let you know if it changes anything or not, but I highly doubt.

Thanks, I already got the same update from seller also. But I ran in to the strange error. I formated USB to Fat32 in Android, and then plugged it in my computer and loaded .img file on that. Unit recognizes USB and asks me to update. I click update, it reboots, writes "Starting to update ..." for like literally 1 second and then says: "Error" and nothing more. After like 30sec unit boots up to normal state and it is all over again.
[Android Head-Units] kalinkamaen:
OK, did you recieve MCU files also? I used FAT and not FAT32.
[Android Head-Units] InZone01:
No, I did not receive MCU files. I highly doubt that the error is in FAT/FAT32 thing, because unit recognizes USB well.
[Android Head-Units] kalinkamaen:
Try to download file once again, could be corrupted. This has happened to me on other files.
[Android Head-Units] bill_viper:
Guys what exactly are MCU files and do they need update?

Many of you are talking about these MCU files..
[Android Head-Units] kalinkamaen:
What is the MCU?

MCU stands for Microcontroller Unit- wiki. The MCU acts as the bridge between the hardware on the head unit and the android system. This allows for special interactions between the vehicle and the head unit that would otherwise be impossible through Android. For example, backup camera view can be activated even if the android operating system hasn't finished booting up. However, the nature of the setup inherently includes a major drawback because the MCU is proprietary. This means software relating to the MCU can only be updated by the specific manufacturer/seller of the head unit. Any problems or bugs in the MCU are unlikely to be fixed unless the manufacturer releases an update- i.e. the bluetooth problem.

[Android Head-Units] bill_viper:
So I understand it's something that it's better not to touch it. :)
[Android Head-Units] swa0000:
Or better - the eventservice apk.

This service opens a serial port and gets the CANBUS datastream and sends specific broadcasts messages to the android system.

Switch e.g. to camera, enable AUX etc will be send also to the canbus via this service to serial
[Android Head-Units] bill_viper:
Οk, ok, that's too technical for me.

As long as it works I won't touch anything else again. My 5 months old Android 4.4 screen screwed up by some Google Play Services. Now I ordered a new one with Android 7.1 and 2gb ram. I won't touch it again, I hope.
[Android Head-Units] InZone01:
I de-attached my DVR from USB1 and attached Memory stick there and it updated everything well. After that my DVR app stopped working and wrote that my DVR is not connected. So I re-installed the DVR app and still same result. So I did Factory Reset in Android menu and now I'm stuck with "Google Play services has stopped" error [emoji4]

So I guess I'll have to downgrade it again, as someone mentioned before downgrading to 20180703 the issue is gone - we'll see.

UPDATE

20180703 Works flawlessly, Google Play Services are working and so do my DVR app. Thumbs up for support guys [emoji4]

UPDATE2

Haha it seems there is no good without bad - my iDrive controller knob is now insresponsive [emoji23]

UPDATE3

Everything good. Had to set to IDRIVE_B in Factory Settings.
[Android Head-Units] bill_viper:
For which android version you're talking about?
[Android Head-Units] InZone01:
2nd Gen Android 7.1.1 2GB RAM

--

Does someone have problem that Android force shut downs apps, which are opened simultaneously? For example I can't navigate using Waze and listen to music via Spotify in the background. Android shuts down Spotify in random 20-30sec. same thing with DVR app also, it just won't stay in the background. The problem exists in 8 times of 10. Sometimes it works. There is plenty of free RAM available, so that can't be the issue. I was hoping that updating device would fix the issue, but it didn't.
[Android Head-Units] kalinkamaen:
First of all, I am happy you fixed the problem. I am on the latest, and only irritating issue I have, is that sometimes when car has been sitting for long time without use. Android is startet without sound. First restart fixes it. Are you running aux directly?

Is it only spotify? or also the bluetooth streaming app? I have no problem listening to music while looking at Sygic navigation. I will test spotify also to see.
[Android Head-Units] InZone01:
I'm using native apps on the unit itself, there is no streaming via Bluetooth. The issue is with every app that sits in background. The app that is opened is working fine and the app that is in the background (for example Spotify, DVR etc). they are shutting down in 20-30sec interval.
[Android Head-Units] kalinkamaen:
I have tested it here and it seems good on my unit. But for me it depends how I exits apps. If I use back arrow it will stop. But if I use home-button it will continue playing.

https://www.youtube.com/watch?v=HY2kxCTstTU

Yes I have streaming over bluetooth.
[Android Head-Units] DRuw:
Thats a service killer in action, native apps are included on a whitelist.

I am busy with the developer from Ugode to get this removed in the 7.1 standard software...
[Android Head-Units] kalinkamaen:
My unit is not doing this.

Thanks for info, Is there other updates we will see i future?
[Android Head-Units] onizuka007:
Which Android image version do you use?

The service killer is active in latest image version and in versions before.

A new image version is planned for this week.
[Android Head-Units] kalinkamaen:

PX3_Android7-1_20180801

EDIT: As information, my unit did not du this on older firmware. There where no difference in after firmware update.

---------- Post added at 04:33 PM ---------- Previous post was at 04:20 PM ----------

Do you know what the updates will be, except taskiller removal?
[Android Head-Units] onizuka007:
That is really strange since a few users including me confirmed that the service killer is active on their 7.1 unit with latest image (20180801).

The update will add more apps (dab, spotifiy, and more) to the whitelist but not fully deactivate the service killer. Don't know about other changes, at least the vendor didn't tell me more.
[Android Head-Units] DRuw:
How do you know?
[Android Head-Units] onizuka007:
I chatted with Louie from Ugode today. We discussed which apps are mostly used in the background and to add to the whitelist.

DAB app will be added for sure.

I made a few other suggestions like spotify, youtube, youtube music, tasker, speed radar detection apps...
[Android Head-Units] kalinkamaen:
As metioned earlier, if I use home button on screen or menu button on idrive songs continue. But if I hit back arrow or slide left on Idrive wheel (same as back arrow) songs stops playing. PLease try this to confirm!
[Android Head-Units] DRuw:
Thats really not helping...

That way, also for the future, they determine which apps to use.

They need to remove the service killer completely or make it possible to change by the user themselves!
[Android Head-Units] onizuka007:
Deactivate it completely is the best option for us, but I have the feeling that they / the manufacturer is not willing to do that.

Device slow down bla bla...you know
[Android Head-Units] InZone01:
Oh, that's good to hear that there's service killer and my unit is not faulty :)

Will wait for update :)

It's also interesting that task killer does not trigger all the time, as sometimes background apps stays, and other time not. Pretty much roulette.
[Android Head-Units] DRuw:
Well, that should be our choice... they indicate the compatibility with the app store, as well as google maps and thats not the case.

I am currently busy with another group-buy of this unit on the bimmerforum and I managed an older group-buy on the same forum for them as well, purely based on my own interest and without any benefit for myself.

I discussed the issue with the service killer thoroughly with Louie and indicated that we, as users are responsible ourself if we run to many or to heavy apps on the unit.

We all know that the unit is not top-of-the-line on hardware but we need simple things to be able to run side-by-side...

What does Louie expect? every time there is a new app which is good to use we send him an email for incorporation in the next software revision?

The DAB app they use for example is crap running in the background and we need the (real)Zoulous edition mention in another thread....

I'll mail Louie again because the next group-buy will depend on that software rev. (after we finally fixed the no-signal issue last week....)

As far as I know there is no other Bluetooth settings available on that device. If OBD had keyboard on it, then you could pair it, but it doesn’t :)
[Android Head-Units] gt2009:
Those of you still fighting with bad GPS signal, I was successfully able to tie in a USB GPS antenna (GlobalSat ND-105C Micro USB GPS Receiver) and get much faster and better location data. You have to enable Mock locations in the developer options (I think it is on by default) and use PL2303 GPSInfo app to tell your phone to use the USB GPS.

[Android Head-Units] kalinkamaen:
Sometimes my unit starts without sound, in my case I have had to stop the car and wait 10-15 secounds, to start the car again for unit to reboot. Here is a simpler option for nonroot version. Now you can reboot on the go. If there is an easier way, pleas speak!

Hi. First of all, i attached an image of my head unit, am I in a right forum topic?
[Android Head-Units] kalinkamaen:
Yes you are, but be aware that there is 2 different versions of this unit one is android 4.4.4 (<-- this is the unit you have) and one is 7.1.1 android. So not all files/firmwares etc will be compatible with your unit.
[Android Head-Units] anson81:
Ah... I see.. I'm still working hard to read all the post as much as I can. But if you can briefly tell solve few of my curiosity question?

1. If the unit is 4.4.4, we can't upgrade it to newer version?

2. What is the MCU server or version for? Should I update it? How to know if it is compatible to mine?

3. As per see the frameworkver and appver... is it upgradable?

4. I saw there is a fix for "no signal" error (that's what I am facing now when using navigation or maybe too heat?) , is it applicable to my case too?

Thank you in advance.
[Android Head-Units] kalinkamaen:
1. To my knowledge you can upgradce you FW, but its still 4.4.4 version. <-- Correct me if I am wrong.

2. Here is some info what MCU is.

3.Appver i think is firmware version, it can be upgraded, doent know about the framwork version.

4. I have had 1 no signal issue with my 7.1.1 version aswell. I also think this have to do with overheating. But I am not 100% sure.

as I understand both units have the sam CPU PX3.

[Android Head-Units] psy460:
[MENTION=2618801]kalinkamaen[/MENTION], did you tried to control recovery with a keybord / mouse on usb ?

for the CPU, rockchip build RK3188 and rk3188-T which is clocked @ 1.4ghz... maybee that why some people there run at low clock speed..

it's possible to check which CPU you have with the CheckRK3188.apk android app.

currently my device is locked in bootloop, i need to buy a microSD card to reflash system, so i can't check anything.

i also seen I2C port on the motherboard, any information about it ?

I will try to flash supersu trough adb shell when i will get my device back to life, and try to make work USB AUDIO to use DAC, because sound quality sucks a lot...
[Android Head-Units] kalinkamaen:
If or when you do this, I really want to know how to do this. Root is a must for me. Sound on my unit is not so bad to be honest, but my car have a external amplifier <-- I am not sure if this helps. could be that my ears are ****ty. I have ordered a aux filter unit because I can hear a low noise between the songs. The bad thing about external USB DAC is that you have to use a certain music player. Is this correct?

I also put in an order on this fan I will try to thermal glue it down to cpu. Hopefully helping against overheating.
[Android Head-Units] psy460:
Let us know for the CPU :)

it could be set to 1.6Ghz if we get root acces.

using rockchip tool you can make update firmawe SDCard or a bootable SD Card. i tried trough USB but it doesn't work, need to use SDCard.

I use also external amp ( Gladen one 120.4 DSP ), i set it also in factory setup, but quality is not that good, bass is crappy.

With USB audio since android 5.0 all sound output is routed to USB.

But on our device it doesn't work, i will try with custom app, but i wish to be able to use Qobuz on my DAC.... probably need to edit audiopolicy.conf
[Android Head-Units] kalinkamaen:
Have you tried to bring down volume in audio settings. It helped allot on my unit. I put it on level 25. Over 25 it sounds like VLC in 125% level.

It's not mentioned, but on the sdcard, the img file modification date is older than the current date, so it's not modified by the program, so yes maybee it's needed.
