Interesting. Did you pair the PC through the Bluetooth app or is the other person wrong and there is a bluetooth settings screen in Android itself?
[MTCD  Android Head Units Q&A] rhetor22:
Ah! I would love to know your secret :) I'll take some pictures of the menu to make sure we're on the same page.

Also, I tried updating the firmware using an SD card formatted to fat32 with the files in the first post. It does not seem to work. I go to system update, it brings me to another page with some system info. Click the update button and it just flashes and then closes. :eek:

[MTCD  Android Head Units Q&A] sterod:
Can you post a screenshot of a screen showing all the paired and connected devices?
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
its starting to sound to me like you dont have the same model as me i have intel 2gb ram ...the update should be automatic once you plug usb into usb socket1 make sure you format usb first .. and that name of file is udate.zip.... not update[1].zip....i would format usb drive with head unit first..then copy update.zip to usb drive..
[MTCD  Android Head Units Q&A] rhetor22:
No Bluetooth in Android menu on mine. Attached is an image of the Android settings menu. Also, the screen where I am entering 1234 as the pairing password. Still doesn't connect. Perhaps a firmware update would resolve this but I cannot get it updated, maybe there is a way to get into recovery and update?
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
thats not the same unit i have look at my first post.......i do not have a joying unit ....does it have 2gb of ram....is it an intel cpu ...if so the rom (update.zip) might work but i cant say for sure...if you wanted to try my rom you might have to flash from recovery but in case you soft brick you must have a copy of stock rom to recover ...
[MTCD  Android Head Units Q&A] rhetor22:
Yep, just noticed that too. Sorry for glazing over that! I purchased it on eBay, the listing shows Atom x3 CPU and 2GB RAM.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
you should run cpux or similar app to find out how much ram and cpu you have.. if it is real a intel cpu x86 the rom (update.zip) should work but you would need to update from recovery boot screen and have a back up of stock rom just in case of brick ... and back up your apps before you flash with apk extractor
[MTCD  Android Head Units Q&A] doitright:
It would be very helpful to get some detailed pictures of the inside of that unit, to see where things are attached, such as the bluetooth antenna. I'm getting a little bit scared of Joying if they've decided to throw out most of the benefits of this upgrade, like proper bluetooth.
[MTCD  Android Head Units Q&A] vincel892:
This makes me lean towards the bonroad 2gb model that k2ckoj@hotmail.com bought. He seems to have no problems so far
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
i dont think rhetor22 has an intel model
[MTCD  Android Head Units Q&A] vincel892:
Also true

His pictures show the new UI that is not consistent with the joying rockchip units.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
if your unit is a intel cpu can you root and do a complete backup of system and ask seller for the rom and upload so we can inspect
[MTCD  Android Head Units Q&A] rhetor22:
Attached are screenshots of cpux
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
please upload you rom so we can look at it
[MTCD  Android Head Units Q&A] doitright:
That would be an x3-C3230RK CPU.

I'm going to go out on a limb and guess that the arm instruction set support is via crazy translator modules. It may actually be able to run ARMv7 (32bit) binaries, but don't expect them to perform well.

Any chance that you could get a dmesg dump from it?

It *should* work from a terminal, type "dmesg > /sdcard/dmesg.dump" or something like that.

I will try tomorrow to backup the apps and flash from recovery with wipe cache and factory reset. I must ask did you rooted your device? Xposed can run? Thanks
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
device is rooted but no exposed..... can you please upload you rom file from seller ..and backup all your apps with apk extractor before you flash if you dont you will loose some ......i would even back up your whole system with nandriod if you have root... make sure you know how to get into recovery if you have to recover from a soft brick and have the original rom from seller to do it...
[MTCD  Android Head Units Q&A] Cid6.7:
Same seller I had same response but different problem my wifi quit working. She gave me a update to flash, I did & it completely ruined my unit, like completely dead. No recovery nothin..

So its in a box somewhere between Vancouver BC & Shenzhen Guandong... 2 to 3 months it'll take to get there... :mad::mad::mad: She promised if I buy a new unit from her she'll send me a refund. As this happened like 2 or 3 days after I could open a dispute.. We'll see what happens I guess...

I think the codes to change Bluetooth are either 0000 or 1111 try both codes if the other doesn't work.. Thats how I got my OBD2 to work with my phone connected
[MTCD  Android Head Units Q&A] MorpheusOp:
I have only the update.zip from the seller, the same you have it. But i think i can backup the rom completely with nandroid.

Or someone can backup the stock rom to have it. I have experience with android phones, i think its the same. Also if the device can be rooted it means that i can install TWRP recovery or something else. How did you rooted your unit? And exposed why not?It wont works?Or....?

---------- Post added at 10:56 PM ---------- Previous post was at 10:49 PM ----------

When you updated the rom do you used the sd card or a usb flash in USB1? also did you checked the option wipe cache/factory reset? Because i`ve updated with success but the android system hangs and all apps are crashing random. No wi-fi problem so far. She said to return the unit and replace it, but i dont want to pay again for shipping. I have 3 days to open a dispute, and if i have no repair with this wipe cache /factory reset, i will open a dispute.

Bluetooth works, i paired the elm with the unit, but connection is not good. It wont work all the time, also connection to ecu of car is difficult.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:

you can not use GPS CARD Slot to read music

you only use USB Slot 2 To read the music " What the ? I cant use a micro sd card that have igo maps or navitel... this chinese is kidding me. I had opened the music player, that playes from the micro sd card.

[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
I don't know of anyone that has made a custom recovery I don't know if you can make one with the computer as far as Google and Google Play services there's updates that you have to let the head unit do and then Google services won't crash anymore do all the updates

.. when I first hooked up my head unit I got the same error messages Google Play services stopped working you need to do all the Google Store updates ..once i got all the updates everything was fine my head unit hasn't crashed since the updates all apps and programs seem to work just fine...
[MTCD  Android Head Units Q&A] MorpheusOp:
Mate i`m not android user from yesterday, i`ve made all updates, and also doesnt have any ration of application updates, because some apps are systems like setting. Do you understand that all the apps are crashing, it`s not like an app or two, i have message of apps crashing between 5 minutes or so interval.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
i think you have to do a full clean install from recovery screen with wiping both cache and partition ..thats the only thing i can think of ...if your unit is like mine i can tell you i have no problems with apps or system crashes....every once in a while i get a force close error thats it ...if a clean install doesnt work then i would say you unit might be defective

It looks like we should be able to get some code and kernel for android 6.0..now we just need to find someone with the skill to build a roms for us

This unit works and sound great..However there are a few thing i would like to adjust...like be able to power off instead of hibernate and or set hibernation time...I would like to have back up of the shipped original rom... And dual boot os..or roms. Change buttons and switches on tool bar...Does anyone know if there is a way to dump mcu firmware....... All ideas and suggestions welcome and appreciated!! ...

[MTCD  Android Head Units Q&A] doitright:
You can, of course, install root on it.

I do NOT suggest supersu, it is an obfuscated binary controlled by an unknown corporation with unknown motivations, I don't consider that at all safe.

Try this instead, safe open source; https://github.com/seSuperuser/Superuser

The binaries you need are "su" and "Superuser.apk" -- which are also available prebuilt and NOT obfuscated here; https://github.com/seSuperuser/AOSP-SU-PATCH/tree/AOSP-N/bin -- although it is ALWAYS safer to build yourself.

No. That is for MTCD-rk3188, which is an ARM CPU.

These are x86 CPUs. Binaries built for ARM will NOT run on x86.

If you install the ARM build, you WILL BRICK your SoM.

---------- Post added at 02:32 PM ---------- Previous post was at 02:30 PM ----------

Well, yeah, but what are you trying to accomplish? Desktop Linux is NOT well suited for car radios, and it will require VERY EXTENSIVE development to replace all that Android software that you need to use even basic functionality in it.

---------- Post added at 02:42 PM ---------- Previous post was at 02:32 PM ----------

The problem isn't finding someone with the skill or the interest. I have that.

The problem is finding the *time*. Now FOR the time consideration, finding MORE people with the skill can really help, because it means that the tasks can be delegated around more developers rather than everything overwhelming one person who has a day job with an hour each way commute and two kids under 4....

And I would definitely SKIP Android 6. There's no point in putting any effort into an obsolete version, which really doesn't add anything useful for these head units over 5.1.

I would skip straight into Android 7.1. The side-by-side multi-window mode would be absolutely ideal for this application. Stick torque fixed into 1/4 of the screen, and navigation into the other 3/4. Would be REALLY slick.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
I wasn't necessary thinking Linux ubuntu only...but if you made bootloader look for a system on a sd card android,linux,windows,exc...you could have a dual boot system....this would be awesome it would make it easier to mod system files and experiment with different os and have the ability to pop out the sd card and be back to stock config if you didn't want to boot off sd card make an sd card to redirect boot loader back to internal system...or if bootloader can't find a os on sd make it default back to internal system. ..I think something like this would be one of the best things that could help speed up development and allow roms that were built for different partition sizes and systems become more Universal .

Anyone want to chime in

Can this be done
[MTCD  Android Head Units Q&A] doitright:
I'm waiting for Joying to make UL128N2 available before purchasing one of these (the kind with the all-glass face and capacitive buttons instead of the big plastic bezel that makes it difficult to pull down the top bar). Until then, I don't know anything about the bootloader implementation in use.

However, what I *can* say, is that this *definitely can* be done.

I can even give you an approximate idea about HOW -- whatever the current boot chain happens to be, the kernel *does not* have to be shoved into the chain where it currently is. In place of the kernel, the boot partition can include *another* bootloader, for example, grub.

The bootloaders prior to the boot partition probably have the partition table baked in to them, and it probably isn't safe to try to mess around with them too much. BUT, what we can do, is manipulate the partition table in MEMORY within grub and the linux kernel. This would allow us to expand the boot partition enough to implement a conventional linux boot partition with multiple kernels and ramdisks, and of course grub can chainload a bootable storage system on alternate storage devices, such as an sdcard.

You will DEFINITELY NOT be able to run windows on it, and frankly, I can't even fathom a reason you'd want to. That is a nightmare from the dark ages of computing that is best left a bad memory.

The head unit JOYING JY-UL135N2 with CPU Intel Atom Sofia come with new firmware structure (neither update.zip nor dupdate.img + dmcu.img like other Joying AMR headunit ). As you can see on this https://drive.google.com/drive/folders/0Bz8umNL1qrsoLVh5cHVSdmVQOWc

I add some file and script to 5009_20.zip to root firmware but the new firmware can't be pass the verify of upgrade screen.

[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
Yes I have seen that that's why I wanted someone to use titanium backup on there unit and do a full backup or nandroid. Also .titanium I believe will generate a update.zip file that could be flashed...once this is done you could just do a standard restore with a titanium or nandroid backup. ....I have reached out to a few people about a multirom boot setup hopefully we can get that to work and boot and flash to sd cards....

Also remember some units are 16gb and others are 32gb so the partition tables will be different. .but that's nothing that can't mod to be fixed...another reason multirom flash to sd card would make life easier

I have the exact same unit as kc2k0j, but I'm still having some issues with mine. The video output doesn't work right(see pic) and I can't get my canbus steering wheel controls to work. I now have the correct wiring harness with a canbus decoder box and have tried every VW canbus option in factory settings but no luck.

Also I took the unit apart over the weekend and noticed a very sloppy solder job on a couple components, see the pictures. From kc2k0j's pictures his solder looks pretty clean, so does anyone know what this section of the MCU board does and if this could be causing some of my problems?
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
I thought someone said they did the update and it fixed the video issue. ..is it the same on both outputs...are there setting on the monitor your using ...also check and see if you get same results if you play a videos file ..my understanding is that you should be able to play movie on external monitor and the home screen on head unit...
[MTCD  Android Head Units Q&A] j2mcentire:
That was me, I thought the update fixed it, but it must have been a coincidence because it only worked once. Both outputs do the same thing, doesn't matter if you're playing a video file. Monitor handles both PAL and NTSC automatically, I've also tried 3 other screens and get the same results with all of them.

Based on my research the older units could play a dvd(actual disc) to the external monitors while the HU had the regular screen, but these new ones(without dvd drives) only mirror what is showing on the HU.
