same here. updates, but still reads as 1.63_2 from Jun 12.

maybe the wrong file was packed in the archive?
[MTCD Software Development] marganron:
hay, just updated to the latest Malaysk ROM, and i got some questions.

1. how can i update my MTCD? do i need to update it?

2. my bluetooth doesn't work good. i can't here from speakers, and i can't transfer contact.

3. when i use Waze and listen to the radio and the Waze give you guide, it only mute the radio for 3 seconds, and i can't here the guide. but if i listen to Spotify, i can here it.

3. is there a Spotify widget? cause in the original ROM i had, it had.

4. why does it take about 20-30 second from when i start my car, to when the OS is up. can i speed it up?

[MTCD Software Development] AssassinsLament:
It seems the folder inside is dated 6/23:

5.1(20160623)

Also, the files inside are (last modified) dated:

dmcu.img - 6/17/2016

dupdate.img - 6/23/2016

So maybe the system update might be new, but the dcmu probably isn't.

I guess it is the same MCU as I am getting v1.63 from Jun 12

I have this exact behavior/bugs in my HA unit, just posting this to be on record.

Also, is there an original firmware link for HotAudio MTCD 5.1? I searched a lot, but I got disoriented by the wiki/all the topics a bit and need some help in this - thanks?
[MTCD Software Development] hadeone:
I've learned to live with it by just letting it sit a bit longer after boot up and closing waze before shutting it off, otherwise it auto restarts and gets stuck. Once it boots fully it seems to work fine. "JY SWC Service has stopped" still happens when the unit comes back from sleep but I haven't had the screen brightness change in a while. Haven't had any fatal crashes leading to a wipe recently. Just an update. V4 seemed to work best for me.
[MTCD Software Development] ikerg:
I just posted it this morning. Hotaudio sent me this on Friday

It is for mtcd 5.1.1

I think [MENTION=3590033]Malaysk[/MENTION] only recently got back from his vacation. This is a part time project for him, we get what we get, but I do agree, it needs work. What's pissing me off the most right now is that the Bluetooth issue remains unresolved. At this point I'm ready to throw more money at anyone who can fix this.
[MTCD Software Development] trap63:
me too.
[MTCD Software Development] sterod:
[MENTION=2366275]doctorman[/MENTION] if you can think of anyone else that can fix the Bluetooth issue, let us know. I'll donate a whole damn head unit at this point if I have to. I'm fed up.
[MTCD Software Development] doctorman:
I am so sorry,

I will see what I can do.
[MTCD Software Development] sterod:
Don't be sorry, it's not your fault and I'm not mad at Malaysk either, I just want it fixed and if it's a matter of money, ill pay as I'm sure will others. It's just too big a flaw to let slide.
[MTCD Software Development] doctorman:
what is the exact model that you have? universal 7"?

Joying says the 4.4.4 ROM has no Bluetooth problem with your Alpconnect app

is that your experience?

They are working right now on an intel Atom head unit with Parrot Bluetooth.

seams like they got into a block fixing the BT on mtcD and 3rd party apps. If I find out more I will let you know.

It is not a Joying specific problem so if any company out there with mtcD fixes this we all will benefit from it.

If mtcB models dont have this problem perhaps I can switch your head unit for you to a mtcB model till the next model is released.

Most people don't use features like that so it is not a huge pressure on the mtcD developers to fix it.

I even offered a reward to the Joying engineers that would fix it, we will see if that will yield something but I am not too optimistic right now. but again we had no hope for android 5 on mtcB and yet another company (klyde I think) made the ROM and we all benefit from it thanks to Malaysk DSA and others.
[MTCD Software Development] sterod:
I've got the the 10" MTCD, same as all the others having the same problem where apps that talk to BT peripherals are told that bluetooth is off then crash when trying to turn it on. I can't say whether the Joying 4.4.4 ROM had this problem or not, as I've never owned a Joying 4.4.4. unit. I can tell you that my previous MTCB unit which ran 4.4.4 (but was a different brand named "NewsMy") did not have this problem, so they may be right.

I disagree with their reasoning that it isn't a major problem that most people encounter. Consider how many people can't use Torque Pro or Dash Command with these MTCD head units simply because their OBD2 Bluetooth dongles don't have the word "OBD2" in the name. For example, I can't even connect my premium OBDLink MX adaptor to my head unit for this exact reason. They intentionally locked it down so the head unit will only be able to discover and pair with the cheap Chinese knock off ELM327 adaptors on eBay. What kind of thinking is that?

Thanks for the offer, but I don't want a MTCB unit, I already have the one I mentioned above. I would like this fixed and I'm happy to pay someone to do it. Its sad we have to bribe the developers of this product to fix the problem, they have no pride in their work. They hit a road block and just give up and knowingly sell a broken product anyway. They should be ashamed they released it with so many flaws.

I asked [MENTION=3590033]Malaysk[/MENTION] if he can hack the ROM to disable the onboard bluetooth adaptor and make a 3rd party usb bluetooth adaptor the primary. Doing so, we simply not use the native ROM's bluetooth audio and phone apps. We would need to run other ones for those features. Another option is if he can somehow make it so that the unit accepts two bluetooth adaptors, the integrated one for the phone and a2dp audio playback, and an add on usb one for everything else. This is how my NewsMy 4.4.4 MTCB device operated. If you can't fix it, work around it I guess.

Anybody having performance issues on boot? It takes about 2 minutes for it to act right if I have the hotspot on but I am on the 2nd release because of the issues some people were having with the newer versions
[MTCD Software Development] nuzzie:
fyi I have the xtrons PF75JCCA , I had ODBIi issues before, just upgraded the firmware to the last vender release dated "latest-Android-5.1-20160805"

I reinstalled torqe Pro (connected bluetooth ODBII first) and torqe pro found the adapter with no issue appears to work fine no fiddling. drove from work 45mins no drops or disconnects.

I didn't try anything else but the ODB adapter and my phone(which always worked)

[MTCD Software Development] hans1983:
As said by others, this is an effort by somebody doing this in his spare time, probably on holiday during the past month as the rest of us have done. Yes there are still some bugs left, some of that more serious then others, but looking at where we are coming from, it is amazing what progress has already been made over the past few months. Initially the unit was sloggy, crashed all the time, lacked important features. With every release bugs are ironed out and new features are being introduced. The documentation is also available so that noobs can get it working right away. This is not something that was done in a couple of rainy Sunday afternoons.

Right now I'm not saying it is perfect, but I went on a 4000km road trip the past few weeks and the unit never crashed, worked snappy and just felt as if it was finished. Sure you have to know you way around a few bugs and it's a shame bluetooth doesn't work properly yet and that Tomtom still doesn't work on this revision.

Let me put it this way. In my company VAG I have a €3500 satnav system, and I would still choose my MTCD-unit with Malaysk firmware over it every day.

Try dashcommand or odblink.....

sent by my S7edge
[MTCD Software Development] nuzzie:
Think the dashcommand is installed by default I'll run it on the way home (about to leave for the day)

And I'll install the odblink if it(dashcommand) works
[MTCD Software Development] ikerg:
Which obd2 adapter do you have?

I can't even pair my odb2 adapter to bt (vgate icar3 - Bluetooth name = V-LINK). V-LINK can be seen by bt module but I can't pair it.

Enviado desde mi D6603 mediante Tapatalk
[MTCD Software Development] nuzzie:
Dashcommand and ODBlink both hang trying to turn on Bluetooth(at least it seems a hang it sits so long) I have a cheap ODB2 Bluetooth adapter (clear blue plastic)

I've tried turning Bluetooth off and they turn it on but hang there.

Open TorqePro it attaches fine to the odb2 adapter and went all the way home with no issue
[MTCD Software Development] whitetigerlgt:
Its because torquepro does not use a BT check before the app calls of to the obd dongle. most other apps do, and that check is where it hangs. Torque will give you BT status though and it fluctuates from on to off and back every couple seconds. There is something really weird about how the OS flags BT to apps. I had hoped by now that someone figured out how to keep it flagged as on as a workaround for this.
[MTCD Software Development] trap63:
So, if you surf over Xtrons forum you will find a wide number of users that claim same issues. Customer support answer with crap instances.

I resume for all:

a) they require to buy proper BT ELM Dongle (black, over $14.00)===== it's the same of generic transparent blue on sale on ebay or aliexpress for few bucks (not exceed $3.50), if you open enclosed miniCD

you will find same directions and same guide,

therefore they don't know what.

b) you are willing to buy 3G dongle (not LTE, Europe runs over 4G and 4G+ from UK to Sweden up to Greece, Italy since 2 years almost - all Companies), do you believe that on HU you can run over PPP? NO, it isn't so.

The adapter ($39,95) 3GDONG008 on HU Android 5.1.1. acts as wifi antenna with SIM card!...It's very crap...'cause you can surf over internet with Android AP from your smartphone. Therefore is unbelievable the scope of buying......(you can extend your data plan in 2016.....not mandatory to buy another SIM/USIM)

Therefore I don't believe

there is the willing to solve these issues

referring to Bluetooth as if your S7 is capable to pair and make/receive callings , if a wifi ELM (cheaper chinese and V-gate) can open and manage data both for Torque Pro and DashCommand...

Another crazy situation is about Mirroring with EasyConnected: S7 it's OK,

S6 Edge don't

(even if is paired!!!!).

I can accept that TomtomGO new doesn't reach network about the crap idea to mark unit with a Serial Id with 23.000,00 Digits (12 are enough, RoadNav on S160 understood several times ago), i can accept that BT ELM doesn't allow pairing with DashCommand...but I cannot accept that this MTCD unit running on Droid doesn't allow to manage a Samsung S6 Edge....

Do they know who is Samsung?

Where they tested this firmware and ROM? over the Moon?

They are (all) very lucky....none of these producers is US and no class action is available.

These units are fake and ****ty instances.

Samsung and other producers solved, among the several release of Lollipop (see wiki), the initial issues for BT. Solved 2 years ago.
[MTCD Software Development] doctorman:
I hear you 100% but the fact is the american name brand units cost 1400$ and some are not even have as functional. Yes the chinese android units have faults but for 200$-400$ including shipping from china what do you expect. the way they survive is by cheap price and volume sale. I dont agree with that personally but after a long search myself I chose Joying android unit for my highlander as my best option for under 400$ plug and play install. a unit like this as brand name would have easily cost 1500$ and 400$ for professional installation. Any how I think instead of moaning about it here we should pressure the seller companies to fix the issue.

The way I see it, there is a manufacturer the makes the motherboard and the SoM which creates the MCU and ROM. this manufacturer sells this technology and mainboard to these sellers which put a physical user interface on them and make them installable and appealing to consumers and sell it. so Joying and Klyde are just the decoration people and the actuall people who make the main board and ROM are higher up out of reach of consumers. those are the people that we have to get to in order to fix the bugs... the only way though is by pressuring all the manufacturing companies to get in touch with the big boys of the main board.

Hello,

I did not read whole thread. Could someone tell something more about problems with bluetooth? What exactly does not work? I assume something is wrong when you try to connect an custom device? It would be good to have any steps to reproduce mentioned issues then I could try to investigate it and prepare some workaround or even solution :).

[MTCD Software Development] Malaysk:
Why did you move applications to the SD card ?? To install the applications in the firmware FUSE assigned to all internal device memory - 13.5 GB !!! Firmware FUSE does not provide the possibility of transferring applications to the SD card, unfortunately.

This is one time when changing the system language. More is not there.
[MTCD Software Development] sterod:
Hi Malaysk, the reason I need to be able to do this is because I run an application called "Plex" which you may have heard of. When I move this application to the SD Card, I am able to select the SD Card (External Storage) as the location for cached movies and videos inside the applications options. This gives me 32 GB to store data. When the application is installed on the internal 16GB partition, the application does not "see" the External SD Card, meaning it is not displayed as an available storage location. 13GB isn't enough to store the movies I sync from Plex to my head unit. Also, all my music was also stored on the 32GB External SD card which I synced from iTunes to my Joying unit through an application called DoubleTwist. Put simply, 13GB just isn't enough. Given the choice, I would gladly accept the tiny 2GB internal partition the way the factory firmware was setup if it gives me the ability to move applications that have large data folders to the external sd card. The new features you have added are great, but in my opinion losing the External SD Card storage for applications is a significant drawback as micro SD cards much larger than the 13gb gained by using FUSE are very inexpensive. I hope you can release a version of your ROM that does not include FUSE if there is no other solution.

Google translator :

RECOVERY UNIT SLAIN to RK3188​

It recommended for those who have no-OTG port and mechanical buttons

(Responsible for the consequences rests with you)

Download the archive, unpack it to any folder (preferably in a way there are no gaps, and Russian letters).

Attached faylSD_Firmware_Tool.zip (489.51 Kb)

The archive is SD_Firmware_Tool.exe program. With its help, we will prepare a boot card.

We also need:

1) Windows PCs having a card reader

2) the microSD-card for 2 - 4 - 8 - 16 GB in fat32 (in the process of all the data on it will be erased).

3) The firmware (file update.img), compatible with the processor and a screen resolution of your PG. Desirable - the same one that was on the device to "brick".

Operating procedure:

1) Insert the card into the card reader PC

2) Run the program SD_Firmware_Tool.exe

3) In the top drop-down list "First: Choose removable disk" select the drive letter that corresponds to the card.

4) The following set box "Upgrade Firmware".

5) Press "Firmware" button and select the firmware file our update.img.

6) Hit "Create" button and wait for the end of the process.

7) Close the program and look at the map. The memory card will appear rksdfw.tag files, sd_boot_config, sdupdate.img

8) Completely disable power radio. That is, even disable BAT wire (yellow), not to mention the ACC (red). It is best to simply pull the main connector on the rear panel.

9) Insert the card into the slot "GPS" radio.

10) Turn on the radio, turn on the main power supply, including the ACC (as a working version - advance include ACC in the car, and then connect the radio to the main connector).

11) Wait a few seconds and do not worry.

12) An indication of the success is a lot of text messages on a black background, similar to what we see during the normal firmware.

13) At the end of the process at the bottom appears "All complete successful! Please remove the sd-card." (Spelling and punctuation of the original).

14) Take out the card and wait for the download radio. If the radio is not rebooted itself after the card is removed, the "help" it by clicking on the Reset button. If the screen is not lit, then briefly press the Power.

Everything - the process is completed.

What to do with the card? The fact that the program format it in a special way, in Windows, you now see it incomplete volume. And it generally can not be used in the radio - or whenever you turn on automatic flashing will go.

The card can be returned to normal size using the same program, there clicking button "Restore". Either keep this card as a tool to restore the radio.
