Same issues here.

Ive got a 10" double din joying clone that bt and wifi wont work. Have tried pretty much what pedracca tried.

Shame though.

Hello, I'm selling one for 80 euro plus shipping. If anyone interested PM me.

Item is located in Spain.
[MTCD Android Head Units General] typos1:
Theres no such thing as a "Joying" and no such thing as a "Joying clone" - Joying are a seller, they sell mainly, but not always, Joyous units, there are about 15 companies making MCTD/E head units, to find out what unit you have go to settings/about device, the letters after "MTCD" or "MTCE" will tell you what unit you have.

Have you opened your unit and looked at how many antennas it has ? What BT module does it have ?

No selling on xda, you have to use Swappa.

Default installed Android ROM?

I have just ordered a "WITSON PX5 Octa-Core +2GB RAM +32GB Coreboard For Android DVD(Android 5.1 upgrade to Android 6.0 directly)" via Aliexpress from 'WITSON Automaster Store'. £67.23 + £7.96 shipping to the UK. Not a bad price (assuming the order doesn't get cancelled and it actually turns up....). It will be going into an Xtrons PF75ATTAR (MTCD GS RK3188) so hopefully it will be plug-&-play.

https://www.aliexpress.com/item/WIT...-5373-4005-a7bb-079c9bc0eb16&rmStoreLevelAB=0

I was just wondering what Android ROM is installed by default on these SoMs? Obviously Android 6.0 but just wondered whether it was a generic ROM that would normally be replaced by the sellers who package them (Xtrons, Erisin etc).

Andy
[MTCD Android Head Units General] typos1:
It will probably be the generic HCT ROM, there is very little difference between the RK3368/PX5 ROMs anyway, its mainly the launcher - bigger manufacturers like Klyde and Kai Ge Le use their own, the seller Roximo also uses their own on the Klyde headunits they sell. You can flash any RK3368/PX5 MTCD/E ROM on it anyway so it soent really matter.

BTW Xtrons is a seller only, there are no "Xtrons" units, look in settings/about device - the letters after "MTCD" or "MTCE" will tell you who makes your unit.

It will be plug n play.

Be aware though, that you may well have to pay import duty on top of the price, particularly if they ship using DHelL.

So... any update on the wifi/bt doesn't work problem?

Problem: Wi-Fi does not turn On (press On, it turns back off), Bluetooth does nothing (can't scan, find, etc. has blank for name and pin, adding name and pin does not fix)

Can't use Terminal, because Termux requries internet, which wifi does not work, ppp widget can't be sideloaded, so it can't work, Terminal Emulator hangs on the keyboard, so I can't use terminal, and so on. Everything requires internet to troubleshoot, and guess what I can't do.

Running CatLog gets me a constant spam of csr_usb: error (giant folder pathname): could not open device file: /dev/goc_blue and associated warnings

Tried the PX3 drivers, they do nothing, it is clearly using px5 drivers still

RTL8723BU is the chip, and no, the PX3 board works flawless with the BT and WiFi, so it is a problem with the PX5 software
[MTCD Android Head Units General] rezzzo:
I have the same problems with wifi and bt. need help please.

Another problem is that I changed the mcu from gs_2.04 to ha_2.59 and recovery rejects to downgrade it again. How can I do that? steering wheel doesn´t work and i can not configure.
[MTCD Android Head Units General] okvp:
Wifi bt problem

Me too! I'm also having the same problem. No bluetoot or wifi. The BT/wifi chip is RTL8723BU. I have tried every bluetooth option from factory menu (the original is MD725) and to change and rename gosac... also tried with different roms and MCU firmware. Works just fine with PX3 SoM, which I'm using right now, but not with the PX5.

My unit is Joying 2din 10.1" JY-UL134

There are also many others with same problem:

If I remember correctly somebody here in forum said that he have px5 with RTL872JBU and bluetooth and wifi is working correctly?
[MTCD Android Head Units General] typos1:
Some units have a dual wifi/bt chip but only have one antenna even though there are ports on the board for 2, this may be a problem.

PX5 board arrived from Witson

The default 'China Post' delivery quoted 30-50-days, however it was shipped on 18th December and arrived on the 29th. Only got around to installing it today as I have not had time. The hardest part was removing the head unit out of the dashboard with the finicky Audi keys....

Disassembling the unit was pretty simple - three screws holding the top on and four screws holding the DVD drive in place. The ribbon cable connecting the DVD drive to the MCU board had silicone/glue around the edges to try and stop you disconnecting them, however there was just enough slack to just rest the drive behind the unit whilst I got the PX3 SoM out.

The PX3 board had three screws holding it in place, however the heat sink on the PX5 board uses the middle hole with a screw holding the heat sink coming in from underneath. I removed this screw and just used the two longer screws supplied with the PX5 SoM to hold it in place (hopefully I won't have any overheating issues....). After that I put it all back together and put it back in the car - no more than 20-minutes work.

On applying power (keys in the ignition) the unit booted (took about 30-seconds I think?) and everything worked. I did upgrade the GS MCU to 2.72 (MTCD->MTCE) with the PX3 board in it before I started and exported the MCU configuration, however I didn't need it.

First thing I did was install Malaysk's latest PX5 ROM and then did some tinkering to get my apps on and my Google account setup. So far everything is working fine. I haven't driven the car with the new hardware in yet but will do tomorrow, however the sound seems much louder (it could just be in my head though).

The speed difference between this and the 1GB PX3 board is HUGE...

Andy
[MTCD Android Head Units General] pedracca:
¿So does the wifi and bt work on your unit? I am assuming it does from what you said, I find it amazing that the very same combination (model/android board) worked in your case, it didn't work for me.

enjoy it, it really is the necessary punch px3 was lacking.
[MTCD Android Head Units General] ADB100:
Yes everything worked pretty much straight away. I have a BT OBDII adapter ($10 eBay thing) and I couldn't pair with it so I started to mess with the factory settings and changed the BT adapter type. This stopped BT working so I put it back and then managed to pair the OBDII adapter through the BT app rather than the BT option in settings and this worked (after changing the PIN to 1234).

I am sure the BT adapter name in the factory settings was different when the PX3 board was in there, however its now MD725 and seems to be working OK. I'll have a bit more of a play later today...

Just installed my 4GB / 32GB PX5 board and all seems great. Wifi working fine, not tested bluetooth yet but usability is so much better, smoother, faster etc... Bought this board, 10 days delivery to UK

Hello,

My equipment currently:

MCU:

MTCD_GS_V1.933_1

Android: 5.1.1

rk3188

I bought today on aliexpress WITSON PX5 Octa-core + 4 GB RAM + 32 GB

My question:

1. Do I have to do something before replacing the board?

2. Is it enough to just create a new board and everything will be OK?

3. If and when do I need to update the MCU?

I sorry for my English, but I am Polish and write by translator
[MTCD Android Head Units General] typos1:
All your questions are already ansered in the thread, read it with a translator, thats what I do with sites in a different language to my mother tongue.

1. No

2. Yes

3. Its always best to have an up to date MCU whatever SoM you have.
[MTCD Android Head Units General] onepabloo:
Thank you for the quick reply.

I read the whole topic and even more I do not have an answer to my questions.

Is it better to update the MCU before replacing the thalamus after?

I can ask for a link to the MCU update file and a guide on how to do it.

Thank you in advance.
[MTCD Android Head Units General] typos1:

Probably best to update before you change the board.

MCUs are in the MCU thread, oin the software section or google "xda mtcd mcu".

Hello All,

I am a Noob here to this forum and thanks to all who have contributed to this amazing thread on improving the PX3/1GB RK3188 units :good: . And yes, I have spent the last three nights reading the entire 55 pages of this thread.

Like many here, I have become so frustrated by the poor cold boot performance of the RK3188/1GB configuration. It's as if it was barely capable from the git go.

I use some pretty intensive aviation mapping apps, iGo, Pandora, Spotify and Weather Channel and the choppiness and slow loading has become unbearable..

My unit is:

MTCD_KBT_V2.42_1

RK3188

Android 5.1.1

Sold by reseller Eonon as their GA6166 for the BMW E53. After complaining to Eonon support of the incredibly terrible cold boot performance and lag issues with their unit they sent me an upgraded ROM (is that the correct term for the operating system?). The name of the .rar file is:

Eonon_KBT1_rk3188_5.1(20170327)

which expands to two files: dmci.img and update.img

These were loaded onto the GPS SD card in FAT32 and the update completed without issue

I have ordered the Witson 4GB/PK5 Octa-Core board and have high hopes that I will have success. I have listed my KBT and Eonon info so that the many people who have E46, E53 and E39 head units from them with this dreaded 1GB RK3188 configuration can find this thread and have hope for their pain.

I have subscribed to this thread and will report back after I perform the PX5 board upgrade.

I welcome any guidance from this community on things I should do before or after my PX5 upgrade so that it goes smoothly. Again, I am a Noob to this area of Android operating systems, so please bear with me while I listen and learn.

Thanks,

Mike
[MTCD Android Head Units General] typos1:
You have a KBT unit.

Your new SoM will be much faster, but the RK3188 is perfectly capable and perfectly good . . . as long as you install [MENTION=5092263]Hal9k_[/MENTION]'s custom ROM, its way faster and way better than any factory ROM.
[MTCD Android Head Units General] semcoinc:
Hi typos1,

Thanks for your guidance on my situation.

I will try to find Hal9k_'s ROM solution or if someone has a quick link please? I just sent him a PM to get the details directly.

Do you recommend the ROM upgrade before I place the PX5 board in my unit or after?

As much as I looked, I did not find a listing for the "KBT" manufacturer. I saw most others but KBT was not showing up.
[MTCD Android Head Units General] typos1:
I ve not heard of KBT before, the letters after MTCD/E always denote the manufacturer.

[MENTION=5092263]Hal9k_[/MENTION]'s thread is in the software section - googlng "hal9k_ xda ROM" or similar should help you find it.
[MTCD Android Head Units General] semcoinc:
Thanks again typos1.

I have found Hal9k_ ROM thread and am digesting it now.

Mike
[MTCD Android Head Units General] typos1:
Forget digesting it, just flash it ! (Use the microG set up).
[MTCD Android Head Units General] semcoinc:
Thanks again typos1 :good:

OK, I have downloaded Hal9k_'s ROM it and will give it a try on my existing RK3188/PX3/1GB MTCD system while waiting for the Witson SoM.

I'll try anything to get some relief from this unbearable 1GB situation with the RK3188.

I have the Eonon supplied ROM backed up on my notebook just in case.

Mike
[MTCD Android Head Units General] abagos:
I have a KBT unit too from Eonon, probably the same motherboard, in a universal 2 DIN package. What is the latest MCU version sent to you by Eonon, the 2.41? If yes, then you need to upgrade to the latest HA MCU (fully compatible) which supports Android 6 and especially the auto sleep function (make sure to note down your factory settings and create an ext file to fix the resolution). I hadn't tried Hal's ROM, and was very frustrated at my unit. The upgrade to the PX5 SoM solved all the problems for me, the unit is now fast and everything works perfectly, even bluetooth calls sound fine (I am on the latest stock ROM).

Please note!!! When replacing the SoM you HAVE to remove the middle screw hole (hope this is the right term) from the motherboard. The new SoM needs two screws instead of three. I hadn't removed it initially and had various problems (the SoM wasn't sitting very well apparently or something was being grounded, however it was working 90%!). You need a soldering iron for this, I removed the motherboard from the box completely to do it).

The upgrade of the ROM while you are waiting will be lost after the SoM upgrade. I had disabled all google apps (google, store, mail, calendar, etc.) and the unit was reasonably responsive.

The upgrade is definitely worth the money and time. It was too embarassing to have the kids mocking me while I couldn't even use the volume knob (it needed 5 min to settle down after booting!)

Alex.
[MTCD Android Head Units General] semcoinc:
Hi Alex,

The latest Eonon/KBT ROM they sent me says V2.42_1.

Hal9k_'s ROM is a huge difference. The apps are still straining at times with the 1GB RAM capacity.

Thanks for your tips on the PX5 upgrade, they will be invaluable to me in getting it installed.

Yeah, good riddance to extended responsiveness of these Eonon HUs.

PS: Outstanding performance with a 56 second cold boot time (per Startup Manager app) and microG framework.

Many "Update Play Services" errors were experienced until I went with the -108 version of microG Services Core.

Was a somewhat painful and tedious journey for this Android novice, but worth the trip.

Mike
[MTCD Android Head Units General] typos1:
The apps are still "straining" cos youre not using the microG setup - all you have to do is select it in settings.

Its not an Eonon head unit its a KBT head unit and the lag applies to all Lollipop MTB/C/D/E head units due to the lack of RAM, the solution is to add more RAM or use microG.
[MTCD Android Head Units General] semcoinc:
Thanks typos1.

Yes, I'm sure you are correct that microG will provide another boost of performance. I may just stay with this configuration for a half day or a full day so I can better appreciate the boosted microG performance.

I've only just done my first non-OEM ROM upgrade :)

And yes, sorry for the Eonon reference. Thanks to this forum I now know that the manufacturer is KBT. I use that Eonon reference here intentionally because I come from several BMW forums where Eonon is promoting "their" BMW specific units and the forum participants may not be aware of the deeper details of these units. Hopefully my Eonon references will show up in searches when they have performance questions and they can become better informed. I intend to post back to my BMW forums with my learnings from here.

Update: OK I couldn't stand it anymore so I took typos1 advice and engaged the microG. WOW! Very impressive performance. My startup Manager says it is booting in 46 seconds!

I have re-entered my Google account info but am still getting an error from the Play Store and in my Google Account settings it is saying "sync is having a problem". I rebooted with reset button and still the "sync problem"

typos1-any guidance is appreciated. I will search this thread to see if I can find the answer as I vaguely recall something about this issue somewhere in this 56 page thread.

Thanks.

Hi [MENTION=456516]typos1[/MENTION]

I have gone to microG on my PX3/RK3188 MTCD setup and it is indeed impressive.

I'm having difficulty with the upgrading Play Store error that some of my apps give me and the play store will not update.

I have followed the install instructions and installed:

https://xdaforums.com/android/apps-games/app-microg-gmscore-floss-play-services-t3217616

GmsCore.apk

GsfProxy.apk

BlankStore.apk

I opened the microG settings as the instructions said and ticked the background services and then opened UnifiedNlp to enable the location backends.

I then rebooted according to the instructions.

I tested the setup with the microG setup and only one box was not checked:

"....Do not have location to test Geocoder. Verify Location backend."

I have looked at this in Unified Nlp settings and I have selected the backends.

Pandora says: Pandora won't run unless you update Google Play Services". But Pandora is playing but I get that notification in the top menu bar.

Any ideas on where I have missed something?

Thanks,

Mike
[MTCD Android Head Units General] typos1:
Have you read all [MENTION=5092263]Hal9k_[/MENTION]'s thread ? There maybe info there, [MENTION=5228031]Johny DJ[/MENTION]'s MTCB/C ROM with microG says you should do this:

1. With disable service app find google play store and disable the first 5 services from top including DailyHygiene.

2. Login to MicroG

3. In microG settings enable google device registration

4. Clear data on Google playstore or clear from recents

5. Enjoy fast 5.1.11. playstore (if not showing paid apps just restart HU)

you could try making sure all thats done.

(We should really discuss this in [MENTION=5092263]Hal9k_[/MENTION]'s thread, though, its way off topic for this thread).
[MTCD Android Head Units General] abagos:
In my case the SoM didn't have the middle screw at all. It arrived without it. Probably some insulating tape would do the job but I was noticing crackling sounds in Bluetooth calls when the car was moving in bumpy roads. That made me think that the SoM was not sitting perfectly on the connector. Probably worth removing it since you'd not want to have to open the case again.
