Funny you asked! I was so damn excited to be back up and running, I jumped right in and loaded all my apps, signed back into everything, adjusted settings then right before shutting down, I grabbed a pic of the build;)

https://1drv.ms/i/s!AkHKmnTUFIO1g5JGkRDlljeueXNGBA

He sent a link to the latest build, app to convert along with extremely primitive instructions (completely understandable as this isn't for the average Joe) He's a good man for that, props to Avin!

Can you send messages yet BTW? Completely unrelated to this but we should probably exchange contact info.
[Android Head-Units] CleanKM:
Looks like the build is the same, whats strange is that three of us have different MCU Versions...

Mind sharing that through PM (either here or bimmerpost).

Not sure about here on XDA, but i can on bimmerpost. Seems like someone eager to take this relationship to the next level. lol :laugh:
[Android Head-Units] jeffc83:
Will try on bimmerpost, thanks. Now to think of what to say to my GF and son;)

This is cracking me up; I sent a PM but it's not in the sent bin. If you don't receive it, I'll type it up again in the AM. (certainly was a day like that haha)
[Android Head-Units] CleanKM:
Didn't get it as of yet.

My MCU Ver. is different (doesn't even display the whole thing) like yours does...
[Android Head-Units] daxtor:
jeffc83 that's how I resurrected my screen as well, by running that utility to create a system upgrade image on the SD card.

By the way, how do I update the MCU version? I haven't heard that can be updated. What good does that do?
[Android Head-Units] CleanKM:
Do we think that this thread should be moved to the Android Head Units Section?
[Android Head-Units] jeffc83:
Maybe both? Categories here are never straight forward and who knows, maybe it'll get more attention there.
[Android Head-Units] kalinkamaen:
Nice, thank you for doing this m8.
[Android Head-Units] psy460:
Nice !

if you are able to boot linux from SD card why are you not able to boot any other img ?
[Android Head-Units] teletype:
Mostly because I only have generic Rockchip documentation and source (which isn't great) and nothing specific to the SOM board in these devices, so it's been slow going. Any image can boot, the problem is getting drivers working correctly. See the corrupted video in TWRP a few posts back.
[Android Head-Units] psy4_60:
Then you would be able to boot original firmware from sdcard , then boot to recevery from terminal and flash firmware ?
[Android Head-Units] psy460:
tried SD cards :

2.12Boot, Fat32 4096byte = device boot

2.12Boot, Fat32 16Kb = device boot

2.19Boot, Fat32 16Kb = SD Boot with black screen, device boot when i remove the card.

2.07Boot, Fat32 16kb = SD Boot with black screen.

hi friends it's weird the sound with the videos works 100% well .. the music 60% no more if it sizzles. I sent a video to the Chinese seller I wait for that answer .... I make a wipe cache partition it's better

I think the software formats your SD card before installing bootable firmware. So I think that what you are formating the SD card to doesnt matter.
[Android Head-Units] 9932ymx:
normally have to format before
[Android Head-Units] kalinkamaen:
Yes but the program formats it after that to!
[Android Head-Units] psy4_60:
Look like it keep setting after flashing.

But i think that we just need to find the right sdboot file
[Android Head-Units] kalinkamaen:
Do agree, I think we have wrong img file.

Is it just me or does this new firmware boot alot faster?? thumbs up on this..
[Android Head-Units] 9932ymx:
it would be better to install the firmware in recovery instead of doing an update .??

and do wipe cache partition ??
[Android Head-Units] kalinkamaen:
I would say with update, no problem without clear cache, but install new rom you should clear cache. Please correct me if I am wrong.

[MENTION=6727112]teletype[/MENTION] is there any reason we can't use the elevated ADB shell to push the su / BusyBox binaries to the system, get the permissions right, and install SuperSU to manage application root access?

I'm thinking of getting this unit for my F10. I currently have an iPod connected to USB for music. Does Android (and this head unit specifically) support accessing music from the iPod?
[Android Head-Units] kalinkamaen:
I can test this for you.

---------- Post added at 10:59 PM ---------- Previous post was at 10:11 PM ----------

Yes it works with the stock music player as you can see under here.

But when browsing music in folders, you will not se Artist, album, song etc. Could be that it will show up when iipod is finished syncing. It seemed like it was syncing the music on android unit. So I had to delete cache on music app to get rid of this afterwards.

This was tested with a Ipod nano 6th gen.
[Android Head-Units] Ironman273:
Thanks for testing it out for me. So it seems that the best way is probably to copy my iTunes folder onto a USB and use it from there? iTunes organizes all the folders automatically already.
[Android Head-Units] teletype:
No technical reason, no. I don't want to mess with my stock image until I've got a working recovery path. That said, I've now got a working u-boot SD image and have TWRP booting off that. Trying to figure out clock timings now and then in theory I should have a recovery SD bootable.
[Android Head-Units] kalinkamaen:
Yes, usb pen or disc is 1000 times easyer to add music anyway. :)

Hello guys, today I got mail from the company (Mekede) I bought my unit from. They gave me their updated firmware. The firmware looks exactly the same as the newest from Ugode. It has exactly the same size PX3.img when unpacked. But if some one wants to try it out here it is:

https://mega.nz/#!XRdFFY5R!DnuImyBnP1l-kmUTHfUbsaRKveFcltMSeZG2mvSpR3Y

Hello Teletype. thanks for sharing your progress.

One question. Would we need linux computer to make this Uboot for sd card, or can we use windows? Is it easy to make?
[Android Head-Units] s1eepwa1ker:
and which car?

I bought my unit from Mekede too for X1 e84. I have trouble with bluetooth. After talking on the phone is lost sound everywhere. After hang up.

It doesnt mather what car you have, this will fit CCC, CIC and NBT both 8.8 inch and 10.25 inch as long as it is the 7.1.1 android version. All have the same softwares.
[Android Head-Units] s1eepwa1ker:
Yes, I installed the version from ugode already. No difference.

And does it matter which car to upgrade the MCU? I think yes.

I have new MCU from mekede wich solve my problem with PDC. but it seems to me that it was the new MCU that broke the sound after the phone conversation.

https://yadi.sk/d/7712djZK3a9etv
[Android Head-Units] kalinkamaen:
Do you have CIC unit? You have to instal MCU for CIC if you have that unit. If you have CCC you need CCC and same with NBT, do no cross install this MCU file. I do not think it possible either.

Have you tried to change bluetooth option? You can try 3 different option i setting menu. And is it only sound on bluetooth, or sound on everything you lost?
[Android Head-Units] Kevvem:
Hello, sorry if I'm borrowing the thread but can't find an answer elsewhere..

I'm wondering if this gen2 will work in a e90 (without nav) if u modify the mount? Or is there anything else that would mess up? If so could a possible fix be to downgrade to the gen1 version of android?
[Android Head-Units] s1eepwa1ker:
I do not have either CCC or CIC. Only bmw professinal with AUX.

what for 3 options? selection of the hardware module in the factory settings? I tried all. Other 2 not work.

Sound lost in all appliactions.

Music visually is playing (progress bar) but i hear silence from speaker. And no reaction on sound bar. It seems that the sound is output to some other channel.

sequence1

1. Play mp3 from sd card

2. call to anybody

3. sound lost, they hear me, but i'm not

sequence2

1. Play music from phone by bluetooth

2. call to anybody

3. i'm hear speaking

4. after hang up, all sound lost

Sound returns after press MEDIA button then MENU button. After message "Make sure CD in AUX mode" sound returns

If your car had Idrive, what would t be? CCC or CIC or NBT?

[Android Head-Units] kalinkamaen:
PLease try CCC MCU file I just uploaded. Sounds like the CIC messed it up for you. If everything was working perfect before, and the cic MCU is the only change made it obvios.
[Android Head-Units] Kevvem:
Thanks for the reply!

I'm gonna cut the dash anyway, but the 2gb ram and newer Android would be worth the extra trouble of the mounting without cutout layout and a specifically made mount, as long as there won't be other problems :D
[Android Head-Units] kalinkamaen:
I would work, I cant see any reason why it should not. The can system on your car is the same as us when it comes to voulme, next and home button. <-- If you have a homebutton. But why not wait until they release a 2 gb version of this unit? <-- On this unit you can get a fake Idrive wheel. But touch on 10.25 is probably not that bad as 8,8 version :)

I installed the android 7.1.1 head unit on my F10 5 series.

The built-in microphone performance is too bad.. like too low level with noise

This android head unit does not have an external microphone jack, so I am trying to exchange or add extension cable(remove internal mic).

Anyone know the voltage (vdc) that goes to the internal mic?

And I updated latest firmware(8/28) After that I start key on, the android HU internal mic is not working. (voice recognition, recording.. etc.)

after reboot the android system(pinhole button or reboot command), mic is working again.

I'm not using android bluetooth function. Have you ever had this problem?

Different rom

I picked up one of these 4.4.4 units for really cheap on Ebay. I plan to use for a digital dash in a car project that I'm working on. I have been able to figure out the wiring from the harness for powering it up and the aux sends.

Using info here I rooted it and am able to reboot the device into recovery. I wonder if I can flash a different rom to it? I do not need the BMW stuff as I'm only interested in using the Android capabilities.

Any insight on what I should do to try this?
[Android Head-Units] 9932ymx:
you can put a picture of your unit
[Android Head-Units] scottydc:
I will tomorrow, it's on my desk at work.

I'm trying to find a way to connect it to a PC the problem is that it has USB A connector coming out of the device (most Android use mini or micro USB B) and the computer also has USB A going into it, both are upstream DATA transfer so as is this setup won't transfer data over usb. I've ordered a USB A bridge cable to see if that'll allow data transfer..

Mine also has a 4 pin header on the mother board that is labeled d+, d-, grd, the fourth pin has no label, I assume it's v+ if so likely another USB or data connection.

My unit does NOT have SD expansion.

a) Just remove all com.szchoice.... stuff .

After that you will have a nearly blank android system and you can access the canbus on ttyS0/115K

b) You cannot connect it directly to USB because of missing MTP host mode.

Use only wireless Debug-Brigde to have access to the device

More regrets and frustrations with this unit that any other device I've ever bought.
[Android Head-Units] kalinkamaen:
OKi, thats strange. Could there be different bluetooth hardware installed in this unit then?

Mine works best on streaming with Feiyitong.

Well, I am out of options the. Hopefully they will fix it on a new MCU upgrade.

I have also sound issue, but in an other way. Sometimes when unit boots up, there is no sound. It was not fixed with upgrading to latest MCU. I have to reboot to fix.

Nice, I have been waiting for this. It came faster then I tought it would be avaiable. I am happy with performance so far on 2 gb ram, if it was not for the sound bug. Price for the 8 core 4 gb is to high now so I would wait and see. It will drop.
[Android Head-Units] bradsinram:
I havent upgraded my CCC yet and was probably gonna order a 7.1 unit. can you tell me a little more about the sound bug? I was probably gonna order mine off aliexpress instead of avin. did you purchase yours from avin?
[Android Head-Units] kalinkamaen:
If you are not in a hurry for this, wait for the 4 gb version. I would not care about android 8, but octa core 1.5 ghz. seems good.

My sound problem, is that sometimes when unit boots up. There is no sound at all. I have to reboot to get sound back. Others have similar problem with loosing sound after bluetooth call. I have original BT so I have only used my bt for streaming, and with no issues.

More progress toward TWRP this weekend. While I have a bootable SD card, video mode is still a problem. The video output is actually handled by the RK616 chip, which the CPU needs to configure using I2C. As far as I can tell, this should be done by U-boot, and is on the stock setup. If I boot Android and then insert my SD and reboot without powering off, the video mode is still correct and TWRP boots fine.

I've tried a few different paths to get it booting correctly without first booting into Android. I tried ripping the stock u-boot.bin and then packing it with a standard stage1 loader. I have not been able to get this to work; it hangs after stage1. I noticed the stock boot sequences uses a miniloader for stage2, which then launches U-boot from the partition starting at 0x2000. I tried using a miniloader binary provided by Rockchip, which I couldn't get to work either. I was able to rip the miniloader image from the stock ROM. This does load from the SD (I confirmed by editing some of the log messages with a hex editor), but then proceeds to load u-boot from MMC rather than the SD card. So this path hasn't yielded success.

I got closer with building an older version of U-boot from source, from an old Radxa repo with a branch specific to RK3188. I didn't use a miniloader here, just concatenated u-boot with the stage1 loader. This works fine, and successfully boots TWRP from the SD card. This is where I run into the video issue. I added some printfs to debug, and I can see that U-boot does try to write to I2C registers on the RK616. I confirmed on a datasheet that these are clock control registers. The problem is I2C doesn't seem to be working at all. Any I2C reads return 0xff, and presumably writes are also not working.

So, that's where I'm at. If anyone has any insight on either of those paths, please let me know.

LOW Brightness

I've read through around 50 pages of this thread and the corresponding one at F30-forum, but still haven't found anyone with same problem as I do. I have the 7.1 unit and my car is F11, I've only had the unit less than two months. My problem is lack of brightness and disappearing of the ID6 interface. It all happened suddenly, one moth ago after starting the car, I noticed that all settings were reseted and brightness was really low in Android menu, only original BMW menu is in normal brightness. I used to have ID6, Mercedes and Audi available in factory menu, but now they are gone. I believe the device has rolled back to some recovery mode.

I have installed two different firmwares, but without any change. I also received factory.xml and other config files from the seller, but I'm not able to install these from the factory menu. File explorer can find the files, but update can't. As my unit is F10/F11, there is no SDcard slot, so USB is only option. Any ideas how to get this working?

I'm pretty sure factory.xml would bring back the ID6, but my bigger concern is the brightness. I can only use navi or android apps during night or in garage, they are not visible at daytime. Brightness is at max in android menu, at BMW menu brightness is 50%, but can't be adjusted. I checked android build file and startup brightness is 200 which sound reasonable, actual brightness is around 100. I installed some brightness adjuster from play store, but that does nothing. I'd really appreciate all ideas and tips to get this brightness topic solved.
