No one who knows how to downgrade? I installed this rom on my HU with 1GB ram and it is extremly slow. So I want to install the Hal9k_Mod_1.3_MTCD_RK3188_1024x600_800х480_eng rom. Can anybody tell me how it works?
[MTCD Software Development] itsjakeo:
Just flash over and wipe everything.
[MTCD Software Development] yves31:
Slow? Not on my 2gb rx3188. Use microG, Radio/Bluetooth/iGo3D.

Edit: severe typo, not 2gb rx3188. I meant 1gb rx3188.
[MTCD Software Development] meazz1:
How did you install Microg?

can you give some pointers?
[MTCD Software Development] yves31:
microG is in the rom. Just activate it. Settings ->extra settings -> mod settings -> framework selection -> microG

In my previous post, I meant 1gb rx3188, not 2gb.

I have a working Huawai LTE USB stick working through UPnP. Problem is, that After sone minutes, the working connection is disconnected from the radio. Any idea how to prevent the radio from doing so? The stick itself is fine and my Interims solution is using a tp-link 3020 with wlan to connect the device. But I would love to have the radio directly connected to the stick for more than 2 minutes
[MTCD Software Development] kabelgleichung:
Internet access using a modem-stick is very unstable with these devices. I also had a lot of problems with different ROMs using my LTE-stick. There are several posts in various ROM-related threads reporting problems. Me (and other users) are using the same workaround as you do. Solution: Stick with your workaround.

I am still testing this but for now it seems to work with the named stick directly in the 3G USB: use a „stay online“ ping app to keep the connection stable and switch WIFI off. I will give you more results in the next days but today, for the first time ever, I had two full drive with no connection losses. (I am not talking about the LTE Stick having no connection, but he Radio cutting the connection to the stick)

PX3

Hello, the first thing I'm sorry for my bad English, I have a little problem with the malaysk image, when I put the SD in the map slot of my px3 it does not read it, it tells me that the format is not compatible, it takes me to the configuration of the SD card and gives me the option to Format and Delete, I give it and the 20% does not go up, I get the error:

- command 37 volume partition disk: 179,32 public failed with 400 37 Command failed

I do not know what happens, but if I put it in the other slot of Micro SD if it works, but before installing your firmware I would go in the two slots, if you can do me a little help, the version I have is the V4 itself perhaps, thank you.

---------- Post added at 03:47 AM ---------- Previous post was at 03:40 AM ----------

[MENTION=5092263]Hal9k_[/MENTION]

Just wanted to say thank you. Your rom fixed a laundry list of issues I was having with the stock rom. The only challenge I had was with errors not recognizing the image on the USB stick. The img name changes with the sd_firmware_tool so I just added the original named img to the stick and the upgrade worked flawlessly.

My unit is a KLYDE manufactured head unit I got from carnaviplayer.com

Specs:

Android	7.1.2

CPU	1.6GHz ARM Cortex A9 x4 (px3 1024x600)

RAM	DDR3 2GB

ROM	16GB Flash

KERNEL	3.0.101+ rocky@hctr930 #894

MCU	MTCE_KLD_v2.80_1

Factory Settings PW: 126
[MTCD Software Development] typos1:
Not from [MENTION=5092263]Hal9k_[/MENTION] anyway, look in the Android Headunit General forum to see if there are any custom ROMs for your device.

Nope, it has a totally different MCU.

Try reformatting the sd card to FAT32 using your computer.

[MTCD Software Development] typos1:
As has been mentioned many times before, the video issue is down to the fact that Nougat units use a Rockchip RK616 audio/video chip which is different to other units.

If your MCU dos not start with "MTCD" or "MTCE" then no.

I see in my app drawer the Viper4Android is already installed and I enabled it but how do I know it work? Is the FX is a different application altogether?

Yes.

See the Viper4android website.

I know Viper4Android and my offline navigation app should have been granted access permission.

Any work around for this?
[MTCD Software Development] szasz.attila:
If you buy the Pro version of SuperSu, you have the list of apps who requested access and can give it from there. That's what I did, could not find any other way to trigger the root permission dialog without the reboot popup covering it.

any fix for the speakers balance app that randomly forgets its settings?

This is a major bug.
[MTCD Software Development] Hal9k_:
Hal9k Mod v2.3 released.

Since the version is made on the new base firmware, OTA update will most likely not be available.

You can install it on top of the previous version without wipe. After the update, you need to go to "Mod settings" to automatically apply the default settings for the new options.
[MTCD Software Development] kabelgleichung:
Just installed your update and will have a closer look at it the next days. Are defaults applied by just entering "Mod settings"? I cannot find a menu option for defaults.
[MTCD Software Development] Hal9k_:
Yes. A simple launch "Mod settings" will cause the default settings for new options.

GPS issues after upgrading to 2.3

Hello Hak9

First off thank you so much for your time and dedication to creating customizations for this deck ! I'll definitely have to send some money your way ;).

That being said in the latest update for some reason GPS seems to be way off / works for a while after a reboot then within waze, google maps etc eventually just starts drifting. Is there something I need to do to resolve this. I did do a fresh clean wipe flash as well as copied the folder to the root that was also included in the image folder.

The other weird thing I've noticed is sometimes the steering wheel control mapping dissapears. It still shows mapped but none of the buttons work. I have to reset and program them all again, then they are fine.

Let me know if you would like some logs and where I can find them.

Keep up the great work !!!!
[MTCD Software Development] Hal9k_:
Hello.

Thank you. :)

Try to run GPS Test Plus when it happens and pay attention to SNSS Status, Accuracy, number of In view and In use satellites.

I don't have that problem. Now I have 3D Fix, 14 meters accuracy, 12 satellites In view and 7 In use.

The coordinates are determined stably.

What folder are you talking about ?

This is an old and known issue with the hardware. It is related to temperature change. Just program the buttons again when they stop working without removing the old mappings.
[MTCD Software Development] wolfery:
Known issues and Troubleshooting
[MTCD Software Development] Hal9k_:
Yes, this app already installed.

You're wrong. There is no such folder in my firmware. But I know whose firmware has it. :D

No. The speed corresponds to the hardware.

Unfortunately, no.
[MTCD Software Development] wolfery:
Wrong Firmware

Now I feel like I am the dumb......

I have you supporting / assisting with someone else's firmware.... Glad you know who it is, would you be so kind as to direct me to the download of your firmware so I can install it and give it a whirl, maybe it's a bug for the GPS in there image.

Updates

So it seems that pulling the GPS module off the top of the deck and putting it into line of sight resolved the connectivity issues for the GPS. Odd that it worked below the dash before and only seemed to show issues now. Better this way anyway, also managed to get your firmware downloaded and installed. Seems quite solid, I did have some issues with it randomly freezing up after installing xposed. Maybe I got a bad version or whichever, I will probably do another wipe tomorrow and slim line the stuff I want to install. I did want to set the buttons on the steering wheel controls to open up Waze / Nav app when long pressed but not seeing any other way to do that then using exposed. Also might try apps to sd card, I think the limitation of the deck is the storage speed and that is what is causing the slow app installation time.

Thanks for you help today !!! especially since it wasn't your rom you were supporting !!! great job :cool:

---------- Post added at 01:24 AM ---------- Previous post was at 01:17 AM ----------

I second this notion !!!
[MTCD Software Development] Hal9k_:
[MENTION=8353817]wolfery[/MENTION], Thank you for support. :)

I think the reason for the accidental freezing is the xposed itself.

You can set Waze as the default navi application in the Settings and bind the navi function for the steering wheel button. (Arrow symbol on the 9th position in the Wheelkey study app.)

As for the internet speed shown in the status bar:

I gave a link to an application that needs to be able to do this.

I do not like this option and I would not like to imitate that "other" firmware. :D

Have just tried to install this unit after removing it around 3 months ago due to a few issues.

One thing that is still happening is kilometres showing on the trip computer and mileage. The car is a 2011 407 peoguet.

Has anyone had anything similar and managed to fix? My guess is the can bus is wrong for the car or the wrong canbus is set in factory settings.
[MTCD Software Development] meazz1:
Installed the v2.3 this morning.

I had to reset the steering wheel control. Did not drive the car yet, all the test were done in the garage. Will post back.

Does this rom have any options for disabling the parking sensor beeping sounds? I have an Eonon ga8163 (or close to that) in my Ford Mondeo and it has parking sensors in front and rear.

[MTCD Software Development] Hal9k_:
[MENTION=8623374]Gianpaice[/MENTION], Yes, this function is conceived as universal. If your player has the option to restore the playback after the start, you can add it to the list.

No, is this the problem! The player doesn't have this function!
[MTCD Software Development] Hal9k_:
