Further on

So we sadly have to assume that no (security) update will ever occur for PX3 devices. Is there any Android Car System where sources are available?

To have an alternative that is open source! What is wrong with having a popular alternative?

How do I use sleep mode? Will sleep mode even work while car is switched off? Will it drain the battery then?

Why not let the user make the decision if he or she wants GPS to autostart with the device? So is there an option to disable GPS autostart or is it not possible?

SD_Firmware_Tool

Hey there

Is it possible to use another software to make Bootable USB rather than SD card?

M HU's SD slot seems to be messy but there are two USB slot No.1 and 2. So I want to ask if somebody has tried to make Bootable USB to boot up N recovery and then go to another Pen Drive to flash.

If you ask which software especially, I'd like to use Rufus to make Bootable USB.
[MTCD Software Development] hypothrax:
Umm, I think I messed up pretty bad. Please help.

I had 5.1.1 lollipop installed. Wanted to upgrade because my TPMS software wasn't working - it was getting stuck at the bluetooth enable prompt.

My device's about box said this:

MCU version：

MTCD_EK_V1.71f_1

Jul 19 2016 17:56:12

Android version：

5.1.1

Kernel version：

3.0.101+

root@chun-book #40

Thu Jul 14 11:14:52 CST 2016

Build number：

rk3188-userdebug 18072016.22:59:38

I followed the instructions on this thread or I thought I did.

1. Formatted a 32GB USB3.0 stick with a FAT32 partition and copied the nupdate.img on the root

2. Formatted a 16GB SD card with FAT32 and used the SD Firmware Tool with the Upgrade Firmware check to prepare it.

Inserted the Card in the GPS slot and plugged the USB in USB1 of the radio.

First time, the radio started and at the Lollipop screen, it gave a text saying ERROR! in the center of the screen.

After a while, it gave me a recovery screen after I ejected the SD card.

At the recovery screen, I tried first to update firmware with the SDcard.

That failed.

I then repeated the process to update via the USB.

That failed as well with the message "Updata failed!" I haven't captured the complete messages but I guess I can rerun the process to capture them if it helps.

Now the radio always looks for the external SD card and does not boot the old system.

How should I proceed?

I went through this forum.

Some people are reporting that the SD card should be ejected at first boot screen.

They are also saying that an older USB stick will work better.

Did I mess up by going for Nougat when I should have gone with Hal9k 1.2 first?

while listening to music from an app > navigate to viper4android and try this:

phone speaker tab; enable master power switch and extra loud switch so they light up blue. then click on the text of "extra loud" so you get a submenu. then turn the rocker switch to max. see if it makes any difference.
[MTCD Software Development] m3tm3t:
I think it should be Unchecked and also some comments mentioned it's better to update your MCU to latest version then flash this ROM.
[MTCD Software Development] zeMadCat:
from what i can tell you made the sd boot so it tries to auto-upgrade the firmware, but the sd card should only put you in a "7.1.2" recovery state..

you have to UNCHECK the upgrade firmware box when preparing the sdcard. all three boxes should be left unchecked.

only select firmware and create, this brings you to the nougat recovery and from there you navigate to apply the update from usb, make sure you wipe data / factorry reset before you reboot after updating.
[MTCD Software Development] hypothrax:
Makes sense. Let me try that and report back. Thanks.
[MTCD Software Development] Hoppengeist:
Also, it will not work for the radio. Only digital streams like mp3 or Spotify...
[MTCD Software Development] hypothrax:
Perfect. It works. Installed it without any errors. I couldn't find the MCU update on the MCU thread. My MCU is MTCD_EK but it worked without it so I will not bother with that. So far so good. I hope TPMS software works now. That was one of the reasons I upgraded.

has anyone tried using a 3G usb modem? does it work ? i have a huawei E352 modem and i can't seem to get it working. did i miss something or should i try getting another modem?
[MTCD Software Development] Hal9k_:
I do not know that.

Nothing but wasted time.

Set "Shutdown delay when ACC OFF" to "Auto sleep". This mode is not limited in time. Power consumption is ~10 мА. The resume time is ~ 5 sec.

HU is not able to boot from a flash drive.

It is very unstable. 4G Wi-Fi mobile router is a best solution.

I have huawei e3372 which works fine. If it does not work for you it also has wifi so you connect to it using wifi. So it shoukd work for you + you can connect other devices to it also.

Hope Simone can Help me with This. I have a specific unit on my Alfa Romeo 159. Its rk3188 1gb RAM. With the factory 5.1 fw the steering wheel buttons were working fine.

After up dating with 7.1, they arent working.

Any tip?
[MTCD Software Development] internest:
Hi!

You need to go to factory settings and select your car model.

Is possible that you have updated your MCU without save the old settings.

Are Radio hardware buttons working fine?
[MTCD Software Development] masri1987:
So I installed 2.1 mod.on my rk3188 mtcd and have no OEM application/folder for diff launchers.. where do.i find it
[MTCD Software Development] Hal9k_:
[MENTION=2694397]masri1987[/MENTION], in the "Apk installer" app.
[MTCD Software Development] masri1987:
Crap, I uninstalled that app! LOL any other way I can get it now? Man I'm an idiot!

I wanted the joying launcher
[MTCD Software Development] Hal9k_:
:D Then install them somehow differently from /system/media/apk

For example, with the help of a Total Commander.
[MTCD Software Development] masri1987:
Thank you I got it.

One last thing some thing continued to intermittently interfere with viper 4 Android... Is there any other thing you can think of? Music fx?
[MTCD Software Development] Hal9k_:
[MENTION=2694397]masri1987[/MENTION], Maybe, Spectrum analyser ?
[MTCD Software Development] masri1987:
What does that do?

Can I safely freeze it with titanium backup?
[MTCD Software Development] Hal9k_:
[MENTION=2694397]masri1987[/MENTION], When spectrum analyser in the music player is active Viper is not work.

This is a well-known fact that has already been discussed.
[MTCD Software Development] nosidefcp:
in the previous 5.1.1 factory firmware, i didnt have anything selected in the factory settings canbus option, regarding the car model. the canbus box made all the job. now, selecting or not the alfa romeo canbus model, the steering wheel buttons wont work. the unit was originally 5.1.1 with a kgl mcu.

when installing the 7.1, after the first iinstall the unit was a little slow, so i flashed it again directly from system updates selecting format flash. unit became very fast but the steering wheel button stoped working. maybe a messed up mcu? can i flash again an updated KGL mcu?
[MTCD Software Development] m3tm3t:
Dear all

Again, I thank [MENTION=5092263]Hal9k_[/MENTION] for his nice attempt. I just flashed my HU using instruction mentioned in the second post from MTCD_KD 5.1.1 to this amazing Rom. After the first boot, the speed of Rom and even touch wondered me. I now am searching to learn how to active MicroG and...

By the way, For those who care, I prepared My 32GB SD card using the SD_Firmware_Utility software V1.4 got from the link below:

https://cloud.mail.ru/public/3f50c9fa2792/Rockchip%20create%20upgrade%20disk%20tool%20v1.4.zip

I had downloaded another software from Chinese link but it had a problem to prepare SD correctly so if you got a problem change your software. Whole the process of flashing took less than 5 minutes. According to some posts, It was mentioned as soon as the N Recovery was seen, it is recommended to eject SD, but for me, it wasn't necessary and I had to keep it connected to the end of flashing process where the radio command to eject the SD card.

Also, there is no necessary to rename anything. The SD utility renames the firmware to sdupdate.img and I did copy the nupdate.img into the 16GB USB.

God bless all kind people who try to help Human beings.:highfive::good:
[MTCD Software Development] masri1987:
So i had no idea what you were talking about so i did a search what i found is the spectrum analyser is related to the MTC Music app? i froze that app altogether. I'm using poweramp and spotify and it happens in both. It didn't happen on ur 5.1.1 rom when i had V4A installed. Something is interfering sir, and it's quite annoying because I have to go back to Viper while i'm driving hit master power off and back on in order for the sound effects to work again.

Please advise, since spotify has no spectrum analyser neither does poweramp, i can take a video of the issue as well.
[MTCD Software Development] s.rahus:
Open the default player that comes with the ROM, play a song. Do you have a music visualizer enabled while playing the song, if yes, turn it off- This should fix the issues with Viper. Then go back to your preferred music player and try again.

My backup camera is one of those triange shaped ones and is flush to the back of the trunk. However the image of the backup camera is displaying upside down. Can you add a setting to the extras section or the mod app for Y-Mirroring?
[MTCD Software Development] Epikarus:
Hi. Love your ROM. Is it okay for feature request? Is it possible to add a option to automatically launch the A2DP app when connected to Bluetooth? Thanks!
[MTCD Software Development] masri1987:
This is confusing

Here's the stock music app. I have no music visualization because I do not use this app at all.

I have tested it again and viper 4 Android does get interrupted by the system and I have to go back into.viper and uncheck and recheck master power.

May I ask how come you add the Home icon to status bar?

What do you mean by the SuperUser app? Should I install it or it's included in Rom by default?
[MTCD Software Development] masri1987:
Can someone point me to this spectrum analyzer?

I doubt this is the culprit since I even had the music app Frozen in titanium backup .

What else could be interfering in such a way
[MTCD Software Development] masri1987:
As u can see from photos one minute apart. Spotify is playing the entire time

One minute it's not processing and I get force close on viper and reoppen app and then it's processing.

I replaced viper 2.5.0.4 with 2.3.4.0 in it's directory with same permissions and will test again , but from the behavior of force closing I can assume that there are other audio related apps or drivers interrupting viper. This wasn't happening on Hal9k mod lollipop.
[MTCD Software Development] s.rahus:
From the picture of your music player, it seems that the music visualizer is already turned off.

(1) Please uninstall the old driver, uninstall the V4A app and reboot (important).

(2) Install the latest apk as mentioned by OP and the recommended driver. Please reboot the unit after doing so (important).

(3) Make sure that the driver status is showing OK

(4) Please play any song in the default music player and toggle the music visualizer by clicking on the button pointed by the green arrow in the first pic attached? In the area circled in the red you see the music visualizer appearing and disappearing. Please observe if there is a change in the behavior when the visualizer is on and off. It has to be off for V4A to work!

(5) If its still not working, then it may be a setting in V4A that's creating the issue. Turn every setting of and turn it on one by one. I am attaching a pic of my current setting. I only have these three turned on.

Cheers,

I use V4A on headset mode because of the wider array of options in those modes. I rolled back to 2.3.4.0 and it seems more stable , i'll keep testing and if it continues I'll do as instructed. Thank you
[MTCD Software Development] typos1:
Have you tried the Lollipop kernel on the Nougat ROM ?

You mean you have a unit where the screen retracts ?

No ROMs have this.

You cant boot from usb and you have to use sdfirmware tolls.

Why dont you just do the 7floor sound mod ? No need for Viper then and the sound is way better.

[MENTION=5092263]Hal9k_[/MENTION] cannot do that cos the camera is controlled by the MCU.

You have installed your camera upside down, just re-install it the correct way up !!
[MTCD Software Development] demetry14:
If I turn the camera 180 degrees then I look at the tops of trees and sky!
[MTCD Software Development] Gianpaice:
Not. I means that i don't completely shut off radio when i go out from my car but it goes into standby.
[MTCD Software Development] typos1:
Well turning it upside down wont cure that.

You ll have to adjust the angle on the camera in that case.
[MTCD Software Development] m3tm3t:
Alright,

I found the answer. To add the Home icon to the status bar I found it in the setting menu

Setting >> Extra setting >> Mod setting >> status bar setting >> Check the Home icon.

Now I want to ask which video format should I use to play Videos on Video app? I've got some music videos on my USB most of them in MP4 format and HD resolution. I played them on previous (stock) ROM well, but now the app says invalid video formatting! what should I do?:cowboy:
[MTCD Software Development] typos1:
Read the thread, all will become clear.
[MTCD Software Development] m3tm3t:
I've done it. Just someone had asked the same question and had found his answer so I asked him but now I found this way. There was not another post talked about the Home icon. Also, about the video, I'm formatting the videos to the same resolution of HU's display to make sure if it's about resolution while I don't know why I had no problem with the same video files on stock ROM. Perhaps it's about Player I will test another Video player later.

Guys,

What dialer you guys use? Can you point me to a dialer with which I can dial by name as well (the stock one can only be used to dial by number from the keypad).

Cheers,

[MTCD Software Development] typos1:
Right sorry, [MENTION=5092263]Hal9k_[/MENTION] said nothing could be done, but your idea of changing the res might work.

---------- Post added at 07:43 PM ---------- Previous post was at 07:39 PM ----------

A PX5 board will make your mic work.
[MTCD Software Development] demetry14:
I would love for that to be explained... Because according to all install info and the actual visual from the backup camera itself the picture just needs to be flipped.
[MTCD Software Development] typos1:
The camera clearly needs to be rotated 90deg, its been installed incorrectly and if the instructions said for it to be installed that way up then theyre wrong and you should contact your seller.
[MTCD Software Development] demetry14:
If the curve faces up the camera looks up at the sky. With the curve down it is perfect yet upside down picture.

Please explain?
[MTCD Software Development] typos1:
A manufacturing fault ? Different camera models depending on where theyre to be mounted ?

Either way theres something wrong, you could try taking the case of and rotating the camera, or as I siad, contacting the seller, but it seems a bit wrong to ask for changes in the ROM (which probably cant be done anyway cos of the MCU) cos you have a faulty camera !
[MTCD Software Development] demetry14:
I tried disassembly and rotating. Not possible in this case due to IP68 compliant and any modification would render that negative. I also asked Hal9k_ and he will at least see if possible. And since X-Mirror is already part of the rom, I assume Y-Mirror will be possible, but we shall see.

Thanks again for your responses... I am just trying to make sure all options are investigated, by myself and Hal9k_.
[MTCD Software Development] typos1:
Ok, I get your point about the X and Y mirroring, but pretty sure the camera is fault, sending it back would be a lot less hassle for [MENTION=5092263]Hal9k_[/MENTION] and it is the seller/manufacturer's fault after all.

I will think about it only if there is a Hal9k_ ROM for PX5.:)

Dear all

I have a question/problem and I am interested if anyone else has experienced it. If I turn on the car after i parked it for a couple.of hours it and the HU wakes up, it takes apprx 4-5 minutes until my SWC seek/change buttons react and I can use SWC until then I can only change/skip songs on the display. Funny thing is volume buttons react immiediately. Anybody any tips?

Thanks in advance
[MTCD Software Development] s.rahus:
I don't have this issue. But just out of curiosity, are you using PowerAmp?

Cheers,

Rahul U S
[MTCD Software Development] matrixx1:
Hi,

Yes i am using poweramp, but it's the same with Spotify. Jetaudio unfortunately takes too long every time when waking the HU until it finds all the mp3s on my ad card, so I don't use it.
[MTCD Software Development] s.rahus:
Okay. I had this issue only once with PowerAmp, I cleared the data or uninstalled and then re installed PowerAmp and that fixed the issue. Your's may be a different issue, though.

Hope the SD card you use supports high speed read/writes, did you try a different SD card or try to copy some songs to local storage and see if this issue is only for the songs in the SD card?

Edit: I mean, just remove the SD card and check if you the same issue.

Cheers,

[MTCD Software Development] matrixx1:
Hi, yes it seems the probléem is caused by Poweramp. Thank you
[MTCD Software Development] Hal9k_:
Yes. It did not work.

Kumarai has a different opinion.

A standard video player is just a shell, a graphical interface.

In the firmware there are two "real" players that play all the multimedia (both video and audio) - the standard NuPlayer and ffplayer, added by Rockchip, in general, for TV sticks.

The first works on a many of Android devices and does not buggy, but it's less omnivorous.

The second is vice versa.

I turned off ffplayer and turned on NuPlayer.

This allowed to get rid of a number of glitches. Including, MapcamDroid began to play normally voice prompts, without stuttering.

For the video, I also installed the MX Player, which has its own decoders. Fortunately, it is controlled from the steering wheel.

Use the AVI format, for example.

MTC dialer really good app.

It allows you to dial numbers from the standard "Contacts" application and also create widgets on the screen to dial your favorite numbers.

A microphone is optional.

I think not.

Check the attached picture.

This is from the store page where I bought my cameras.

If you can not configure your camera, I think it's easier to order another one with the right settings.

Issues with time settings

I have been having the following issue with the time settings with version 2.1

1) After the system boots up, it takes up to 2 minutes before the time and dates update to current date and time.

2) When the date and time update, the time is 1 hour behind than what it should be. I have selected the time zone to be Eastern DST Zone.

3) I have tried different combinations including get time from GPS, get time from network and manually set the time. In either scenario the above two issues is what I see.

Are there any recommended settings for the setting the time correctly and update quickly upon boot up.
[MTCD Software Development] Hal9k_:
This should not happen if you correctly connected the power to the HU.

12V must always be on the yellow wire (BAT, B+, etc.)

I have already updated time zone files. This will be available in the next version.
[MTCD Software Development] jigubhai2001:
I am sure I have connected the Yellow wire to Constant 12 VDC (Battery +) and the red wire to Ignition switched 12 VDC. I will double check it.

So I have two separate question about this,

1) If I disconnect the Red ignition switched 12VDC wire, then will the canbus turn on the unit? or this is dependent on the Canbus module. My car is 2008 Mercedes ML.

2) If I connect the Red ignition wire to Constant 12VDC (Battery +) also, then will the unit just go to deep sleep and turn on/off via Canbus?

Thank you

[MTCD Software Development] typos1:
If only, someone has even offered to buy him an RK3368/PX5 board.

Ok, the factory Nougat units use a Rockchip RK616 audio/video controller chip, unlike the other units, I think its that which is causing the problem.

The XRC RK3188/PX3 units have a bug where the mic does not work outside the BT app, however, if the SoM on these units is repalced with an RK3368/PX5 SoM, then the mic DOES work outside of the BT app - I ve done this myself and so have others.

The red lead should go to the CAN Bus box, the yellow should go from the CAN Bus box to the unit.
[MTCD Software Development] jigubhai2001:
I am not sure if I follow. In aftermarket units the Yellow wire goes to the Battery and the Red goes to ignition switch.

In the case of these MTC C, D, E radios I think the canbus module is already prewired into the wiring harness and there is open Yellow and Red leads.

Therefore I am not sure what I need to check or change in the wiring. Can you please show some pictures.
[MTCD Software Development] typos1:
In ALL headunits the yellow goes to the battery and the red to the ignition.

MTCB/C/D/E units are no different.

For CAN Bus cars, the ignition lead goes to the CAN Bus box which then sends the ignition signal to the unit.
