in video 1:40 - lable on HU - look at it, there should be a pin information

make a photo of the quality of this label and place it here - I think you can help.
[MTCD Android Head Units General] truitor:
I can send you whatever you want of course !!!

Ok great I'll check that carefully.

Thanks a lot guys !
[MTCD Android Head Units General] PekeMM:
Here are pics of one of cables I got. Have you got one of those? Can you take picture of both ends of that cable and one you disconnected from your car?

As I got two I have created my own harness in the end and that one is plain ISO if I ever need it and fo use in my service to connect HU directly on table for tests instead of sitting in car.

MODS: shouldn't this be split into new topic?
[MTCD Android Head Units General] truitor:
Guys : here are some pics.

https://drive.google.com/open?id=1OGxuIC8J6O-1c22Vmx2uX9CbFIofJoRg

I think power cables are the big black and yellow ones ?

So I can try to put a power supply 12v @ 2A on these two pins ?

What can I try more for you ?
[MTCD Android Head Units General] kumarai:
Hi my friend!

I see you are interested in NAND?

Here is a compatible chip from Samsung

http://www.samsung.com/global/business/semiconductor/file/media/Samsung_eMMC_2013_Final_HR-0.pdf

High-Performance eMMC-Pro!!!

Video https://www.instagram.com/p/BdwmDd4lTr-/ , on the left on the chip eMMC 5.0, right stock chip NAND.

As you can see, for 5 seconds the load is faster, the reading gain +50 mb

I'm sure Oreo can easily be flashed, the partition table is not a problem. If people are not going to share Oreo, we'll find where to get it. A matter of time.
[MTCD Android Head Units General] klaariskees:
Thank you kumarai, your info is very welcome to me! Which chip did you exactly use? I was looking for 128GB eMMC, but 64GB also will do.
[MTCD Android Head Units General] PekeMM:
You have standard WV Connector that also have OEM AMP (Bose?)

You will need three wires as you need to connect YELLOW and RED together before you connect it to +12V. !!!!!DO NOT CONNECT CAN BUS!!!! While you power it on DESK

Here are the pics please check Colors of wires before Connect anything.

In this example I used standard 5.25"-> SATA POWER CABLE Converter Cable that I cut in order to connect to Car stereo ISO Cable and used it to power the unit from standard PC PSU from My Desktop PC and it should power up as soon as you connect the power (Turn ON PC)

My best guess as that your unit do not power up cables, pinouts and connectors on your dashboard is bit different. eg more like one I'm attaching for WV Jetta 2005 so cable that they sent you (possible CANBUS Also) is wrong and it is logical that Device is not powering up and you should get right harness like one I got for Jetta (Think they call it BIG WV Harness) and possibly different CANBUS (Not sure if one they sent you is compatible). To confirm that you would need to take picture of Connector in your Dashboard.

Let me know if you need any more instructions.
[MTCD Android Head Units General] typos1:
It has not been confirmed that Oreo will not work, Dasaita manufacturer motherboards and head units, they do not make the SoMs or the software. HCT make the SoMs and do the development, so its not HotAudio's fault if Oreo doesnt work, but as I said its early days yet, we dont know for certain it wont work. As youre a dev why dont you see if you can get to work ?

It wasnt me that wanted the nand.

I am happy to provide you with the firmware (pm me), I just asked how you proposed to get it working.
[MTCD Android Head Units General] PekeMM:
I wish if I could have time. Got rusty over past 10 years, too much work and not single anymore, also there are kids and I price family over any hobby. I only can do as much as possible along work I'm paid for to do with device unless I want to get up 2h earlier and have 26h day instead 24h ;) And I think it is at least half of it is their fault.

I'm sure that they will make new SoM, thus I explicitly asked will my SoM work with Oreo and got the confirmation that it would. Now new SoM is needed with Oreo Preloaded. Only reason I can think of is that they find it cheaper to do it that way and I know it is much cheaper to do it that way. Far less Research/Developing/Optimization than simply just put it to new board. Users ....w you you need to pay for new board even you bought old one a week ago under false pretense that it will work and be upgraded to Oreo.
[MTCD Android Head Units General] Oberbergler:
I've asked Dasaita if it is possible to update from Android 6 to 8 and got the following answer: The android 8.0 need the large ram support(4G ram, they use new px5 chip), the engineer found he can't update 6.0 to 8.0 successfully.

Don't know if it is true, in September they were sure that it is possible to update.
[MTCD Android Head Units General] truitor:
Here is the picture of my dashboard connector :)

Thanks again for the reply I'll check that carefullly. I have some power supply at work so I can put anything useful directly without using PC PSU.
[MTCD Android Head Units General] Cruze Atr:
Hi. I would like to ask if there is any update for my unit which has these characteristics :

versión mcu: mtcd_ha_v2.38_1 mar 14 2017 09:23:17

versión de android: 5.1.1

versión del kernel: 3.0.101+ chun@hctr930 #296 thu mar 2 10:54:50 cst 2017

número de compilación: rk3188-userdebug 07032017.11:28:08.

Could it be updated to 7.1.1 without the need for root? My unit is 1gb ram 16gb rom for Chevrolet Cruze

Thanks
[MTCD Android Head Units General] PekeMM:
You do not have PX5 Device but PX3 with 1GB/16GB Try here https://xdaforums.com/android-auto/...lopment/rom-malaysk-roms-mtcd-device-t3385309 it is your best approach from my personal experience 5.1.1 have bit outdated interface and Malaysk ROM is much better.
[MTCD Android Head Units General] PekeMM:
Sorry again, I was suspecting something like that and I can't seams to locate the connector pinout http://www.tehnomagazin.com/Auto-radio-car-connector/VW-Car-Radio-Wiring-Connector.htm

I know I bother you with constant remove of your OEM Stereo but I can't seams to figure out pinouts, so I would need little bit more information on the functioning and harness.

For now facts I'm certain of are:

- CanBus Controls power on/off (Little black box) (your Previous Pic)

- You have dedicated Battery and Ground wires out of ISO part of WV connector (That BLACK and YELLOW thick wire)

- You have Front Speakers on ISO (That Light BROWN ISO Connector)

- You have PHONE, CD Charger/AMP and most likely Climate Control Connector??? (GREEN and BLUE)

- I do not know what is your White Connector :(:confused::confused::confused:

So please try to take few pictures of back side of your connector so that I can see all the connected PINS and Cable colors, Take Picture of your Dashboard with OEM Radio installed and Try to locate big sticket with pinouts (Like in my Jetta 2005 PIC or like in this example pic https://ssli.ebayimg.com/images/g/losAAOSwRaRZrFaC/s-l1600.jpg all stereos must have it top or bottom and even these Head units have it) that should give me glimpse of Radio Make and model to search for Service Schematics and see the pinouts?

Also can you give us Exact Make, Model and Year of Manufacturing of your WV POLO?

From what I see at https://www.aliexpress.com/store/pr...o-2012-with-Octa-Core/600991_32848747333.html you should have got two types of Harness Cables.

Another if you have spare PC PSU here is a pic of PINS (GREEN + BLACK next to eachother) that you need to Short-wire in order to jump start it.
[MTCD Android Head Units General] PekeMM:
September??? They were sure on 11th of November that My 4GB device WILL Support Oreo 8.0 5 Minutes before I clicked on BUY button or I would not buy Two of them and would wait for Oreo Device.

What do we have ATM?

- OTA Update Image ZIP???? What device it is intended for?

- Anyone own device with Oreo ???? Can we at least extract Image of it????

- Is new Oreo Device confirmed that it is PX5 rk3388 or some sort of A72 6 Core????
[MTCD Android Head Units General] truitor:
Hello again Peke :)

You do not bother me of course, any answer is good to take even if it's to say that you don't know !!

I'll make a lot of picture tomorrow morning of eom HU front and back, and new dasaita HU with cables. I'll make pictures of the whole dashboard too in order to see which features I can have.

It's true that I have 2 types of power cables for the new HU named A and B on the link you shared on AliExpress. At first, I did'nt even received the A type, just the B type with the new HU. So I contacted the seller because the B type is useless for me as I can't use it on the car dashboard. I've not taken pictures of it since anyway I can't use it but if you want I can take some of course.

Anyway thanks a lot for your answer and the time you take to try to help me.
[MTCD Android Head Units General] Oberbergler:
No, in September they told me that it is possible to update. Today I've asked again and they answered that it is not possible.
[MTCD Android Head Units General] PekeMM:
Ok so we need to get hands on one of OTA images at least we find the way to Extract to see what and where we are on it. Also we should know what device it is meant for. Or someone with Oreo working HU willing to go thru Image Extract.

When I ordered 4GB device they said I'll have new Core board. I'm getting really frustrated about all of this.
[MTCD Android Head Units General] typos1:
I suggested earlier that maybe its only the SoMs with 4Gb RAM which are a later revision (4 I think) that can update using the provided files, hearing this from HA makes me think that I may have been right and I have a 4Gb RAM unit, thing is without an update image we dont know how to flash it, unless a dev can make an update image from the zip.

Also, no dis-respect to HA, but they simply manufacture motherboards and head units, development is not their speciality an as I ve also pointed out before, HCT do the development, not the head unit manufacturers.

And as I also have said before I think HA truly thought that Oreo could be flashed on all RK3368/PX5 SoMs, I really dont think they mislead anyone on purpose.

A few years back the seller Joying said that the MTCB units could not be updated to Lollipop and yet Klyde bought out MTCB units with a Lollipop ROM that only worked on units with updated MTCC MCUs, within a few months people on here and on 4pda.ru got Lollipop working on all RK3188 MTCB units with MTCB or MTCC MCUs. This proves that the headunit manufactures dont know too much about what it is theyre assembling and that the community will group together and get things working, I think we will get Oreo working eventually, just have patience.

Yes, there is a Nougat update for your unit made by [MENTION=5092263]Hal9k_[/MENTION] its discussed in one of the Dasaita/HA threads, I cant remember which, so you ll have to search them, it shouldnt take too long, theres only 3 or 4. (I think it may "New Again Dasaita . . ." and has some pictures of new units including quadcore Nougat and octacore Marshmallow in the first few posts.

.It is deffo an RK3368 device.
[MTCD Android Head Units General] PekeMM:
Update Zip can be analyzed it can be very useful I think. I have 4GB RAM device See attached Picture.

OK I understand that but if they are partners why do not they use us to help them to make things better and even make better partnership with HCT, I can make whole iGO branding stuff that they just need to put onto GPS SDCard, pointed out an issues in code (Along with code solution and video of solution), offer them to make it better marketed and earn more money on sales, suggested hardware motherboard upgrade and add 10 Band EQ in front of TDA AMP and/or line out along with software APK (supplied with their devices under DASITA brand).

They are doing the final product and they should parses fixes to HCT. If they give me HCT contact address and I'll call them, maybe even make some contract instead of offer it to Dasaita as I think they have potential as manufacturer and brand. As example I know GoldStar when they were not called LG and were just small manufacturers. This is not the way you treat your customers, especially if they help you earn the money and rise above others.

Exactly, help us to get right images and we will find them the solution that they can pass to HCT on a plate and make it better on update.

OK, at least some good news.
[MTCD Android Head Units General] maniep:
Glad it help you :)
[MTCD Android Head Units General] stinger4321:
Have you done this upgrade? Does someone sell this already modded?
[MTCD Android Head Units General] Oberbergler:
I don't think that 4 gb units with Android 6 can be updated and 2 gb units not. Think of the RAM upgrade on MTCB/C/D. It was no problem to upgrade from 1 gb to 2 gb.

I actually don't know if PX3 headunits with 1gb can update without modifications to 7.1 but they can.

Android 8 supports 2 gb RAM devices, so why should't it be possible?
[MTCD Android Head Units General] megatm:
Well, after reading the thread, I'll give my opinion.

First of all, I think that the manufacturer and the developer need to specify who are they customers, and what they want to deliver. What is the most important thing, or the primary function, in a HU? The sound. A good part of the users want a good quality, some of them a superior quality. Talking about a good DSP, or maybe a support for USB audio like was mentioned before. Plus that, everyone wants a stable system, no GPS lost, not popping sound, no random resets or turn off, good quality Bluetooth. I know the anxiety for a update. I'm like this with my phone, checking apkmirror twice a day, aptoide and sammobile. But I think that we have a lot of bugs in the actual software and if we jump to oreo, we will increase this bugs at this moment. Please, as I said, I'm not against updates, but I think the focus and the goals should be give us a stable and reliable system, not forgetting the primary purpose that's the sound. If the purpose is to deliver a uptodate system, always if the latest kernel, even if it is buggy, just to say that you have the last one, users must know that.

Finally, I don't expect that everyone agree with me, it's just my opinion. I respect any different opinion.

Hi, i found HCT PX5 8.0 oreo update file at yadi.sk/d/umCvHqCDzHccr/RockChip%20PX5%20%20Android%208.0/HA

but file is encypted and i guess if we try to update HU would be brick ?
[MTCD Android Head Units General] klaariskees:
I have ordered a PX5 4GB SoM and a SAMSUNG DRAM NAND flash storage KLMCG8GEAC-B031 64GB chip.

It will take maybe 2 month to deliver, so I have to be patience!
[MTCD Android Head Units General] piyush7243:
Something off topic. Is Magisk supported on MTCD?
[MTCD Android Head Units General] stinger4321:
Where did you order this from? Will this upgraded px5 include Oreo?
[MTCD Android Head Units General] klaariskees:
PX5 board (Alibaba Witson reseller) wil not have Oreo on it. The flash storage is a separate order from another store (Alibaba https://www.alibaba.com/product-det...ml?spm=a2700.7724838.2017115.1.41e0a320C9YLt9 ).

Hi [MENTION=8793619]PekeMM[/MENTION] [MENTION=8198358]Floston[/MENTION],

Link to the pictures / videos : https://drive.google.com/open?id=1OGxuIC8J6O-1c22Vmx2uX9CbFIofJoRg

I've added a lot of pictures for the HU, cables, even the one I can't use (type B).

I've plugged a power supply on the 15 & 16 pins of the HU, directly and with the type A cable.

The front HU left buttons are just bliking, for 1sec then nothing. I've added a video of that behavior.

I don't really know what I can try more ... Do you have any ideas ?

Have a nice day. BR
[MTCD Android Head Units General] klaariskees:
Looks like what I had with my V600. The problem was a defective PX5 board. Dasaita sent me a new one and the problem was solved.
[MTCD Android Head Units General] PekeMM:
Yes, all is much clear now, Will post you later with schematic, and it should be easier to Use Cable B as it is more to ISO standard and is easier to tweak on Table.

Re Blinking: It is normal as you only supplied BATTERY and GND and with those two cable only connected device will not power up.

You are still missing the Dashboard pics, OEM Stereo Pictures with connector sticker and Dashboard Cabling pictures from back side of connector if possible. I need to see it if I want to build you custom Connector schematics.

Try to Buy a cable like attached one so that we can use it with cable B.
[MTCD Android Head Units General] PekeMM:
As promised Here is a picture of Connection schematics. You will see that you only connected Yellow wire-> +12V and Black -> GND instead Yellow + RED -> +12V and Black -> GND. Now when you connect all it should power up or like klaariskees said

you make video as you may have defective board. Which I doubt as it Will POWER UP NOW.

Regarding CABLE A: That really loos like a terrible mess and form one side you get USB + 5V/FakraVW_USB(???), no ACC Wire to HU from dashboard Connect, but it look like ACC goes to CANBUS and CANBUS receive Yellow WIRE, which means that ECU tells CANBUS Key is in Ignition (maybe you also have Start/Stop+ECO Redlight turn off) which then pass +12V to HU on ACC and HU Powers up. It is very hard to tell from this side of pictures and I can't physically use multimer and check/map Shorts+Culorring+CanBus+OEMConnector+OEMStereo. Damn I hope you will not need to go to some Service and get it fit up as they will skin your wallet (I would 100%).

Lets first get it powered up and then more pictures of Cabling and Connections and Dashboard and OEM cabling and OEM Connections and OEM Stereo (Find that Sticker like one on Dasaita with pin-out description) so that we can make our own harness or make pinout schematics so that they can send you the RIGHT CABLE and Possibly Different CANBUS (at price for sure).

You still havent told us What year is your VW Polo and what Audio/Infotainment/Entertainment OEM package you have?
[MTCD Android Head Units General] dominicanodcora:
hi everyone. i have the jeep wrangler specific 10.1" dasaita 8 core px5 and my steering wheel controls stopped working. can anyone help?
[MTCD Android Head Units General] CadillacMike:
If they worked previously and stopped working, then that is a little odd.

You can try a software update or a reboot.

You can see how to update it here

[youtube]DPeikQzGdRA[/youtube]
[MTCD Android Head Units General] typos1:
Blinking LEDs suggest that the unit is in recovery.
[MTCD Android Head Units General] dominicanodcora:
i did a factory wipe. i did the upgrade and mcu upgrade. still experiencing the same issue. i tried honking the horn as well when i searched other wrangler users experiencing loss of steering wheel controls. So...... if i do a factory reset should that also reset the boot up logo to android? i have it set to Jeep logo and that does not reset to android boot logo when i perform a factory reset. i am trying o boot up to recovery to wipe cache and wipe device from there. i have had no luck booting to recovery.
[MTCD Android Head Units General] CadillacMike:
If you go to the factory settings there is a setting for the Canbus, I think for the Jeep it was set to Bagoo or something like that, I show it in one of my videos
[MTCD Android Head Units General] dominicanodcora:
i tried all the options listed as jeep under canbus. i wonder if theres a way to revert to factory the device to the point where i can choose the jeep logo again. tomorrow i will install my stock radio and confirm steering wheel volume and change track button works.
[MTCD Android Head Units General] CadillacMike:
No that's what I am saying, the Canbus wasn't listed as Jeep it was listed as something I never heard of, I think bagoo
[MTCD Android Head Units General] dominicanodcora:
yes. i looked at your video and posted a comment. i will try that setting in canbus and see if it takes the change after the reboot. fyi i have not changed the canbus setting since i got the radio. must had changed on its own. its set to all like nothing has been chosen.
[MTCD Android Head Units General] PekeMM:
From what I know and see on my device it blinks once when you get bat power and three times when it is in recovery. He didn't had power connected correctly wit Cable A with Cable B it should be better for on table tests.
[MTCD Android Head Units General] typos1:
Bagoo is the name of one of the manufacturers of CAN Bus boxes these untis use, so are Simple, Raise ad Union.

I see, I ve not heard of a unit blinking once for battery power, some units flash the LEDs constantly in recovery, some only flash constantly when theyre flashing something from recovery.
[MTCD Android Head Units General] dominicanodcora:
it works now. i chosed bagoo chrysler just like on your video Mike. thanks.

Yes, it is a bga package. I will ask a friend of mine, to do the hot air soldering
[MTCD Android Head Units General] iwl:
Because the never got 6.0 stable, google maps hangs, other crashes, music stutter.

May be other things can also be fixed with the update like proper switch off and on with power button.

Hi Peke,

Thanks again for your help ;)

I'll try to find the car manual to get you the exact version of the car ! I'll make photo of the full dashboard too in the same time. For the EOM HU I'll take picture of the back so I hope it shows HU brand/version.

I forgot about connecting ACC, I'll try that today with "cable-B".

Regarding cable-A I don't know why ACC is going threw canbus. For me it was not something odd at first. Anyway I can try cable-B with ACC in my work lab just for booting.

BR
[MTCD Android Head Units General] truitor:
So I've tried to put 12V on ACC and it finally boots. Can we conclude that the can bus adaptator is either

- dead

- wrongly programmed

- not the good device for my car ?

What other cause would you see ?
