I installed 7 on mine px3 and a lot of lag no video in all apps and to downgrade very complicated
[MTCD Software Development] masri1987:
i have a specific question, when using google maps, the audio when music is playing seems to be lowered in volume from time to time, despite me having "voice" off in navigation (gmaps)? Anyway to disable google maps from having any access to audio whatsoever on a system level?
[MTCD Software Development] akslow:
good :) thx
[MTCD Software Development] dude-nl:
Any ETA on the 2.1?

I need to downgrade because of black video screen and Wifi disabling when comming out of sleep (2GB px3).

This wasn't before the upgrade to 7.1.2
[MTCD Software Development] Hal9k_:
Hal9k Mod v1.3 was released.

It contains the same changes as version 2.1 (and even slightly more).

I invite everyone to the first post. :)
[MTCD Software Development] scorpio123:
Great job. Thx.
[MTCD Software Development] fliperpl:
it is possible to get audio codec working with radio FM? I am at 1.3 version.. Its so much better than equalizer build in software
[MTCD Software Development] Hal9k_:
No. Because the FM radio does not use the Android audio codec.
[MTCD Software Development] dude-nl:
Do we have to wipe clean? Or just install over 1.2?
[MTCD Software Development] Hal9k_:
As I wrote in the first post: If you are upgrading from a previous version, no data deletion is required, but it is recommended. Especially if you used microG in the previous version.
[MTCD Software Development] kehadamus:
I set steering wheel keys. Then the volume key is working properly. Others are failing.

[MTCD Software Development] Hal9k_:
Show the screen with the settings of the steering wheel keys.

Do you have a CAN Bus adapter ?

Thanks alot

I want to ask if this rom compatible with device rk3188 mtcd-mlt-v1.6
[MTCD Software Development] dude-nl:
I can't get the app "autostart" to work to start Radio and Tomtom when the unit boots.

On the other ROM's it works.

Do I need to do something extra? Or are there other options to start some apps from boot?
[MTCD Software Development] Hal9k_:
It's compartible with any rk3188 mtcD device. mcu it is desirable to update.

And why ?
[MTCD Software Development] chandlerp:
I'm on the 7.1 ROM at the moment and having stability issues. Is it easy to go back to this ROM? Is it just a case of boot to recovery and flash this ROM or do I need to use a different recovery to the Nougat one?
[MTCD Software Development] typos1:
You need the Lollipop recovery, make a bootable sdcard with the Lollipop ROM to get into Lollipop recovery then flash the Lollipop ROM from there.
[MTCD Software Development] Hal9k_:
[MENTION=331230]chandlerp[/MENTION], Yes, the procedure is completely identical to the installation of Nougat.

Netflix 0013

Hello there.

I just installed your mod. it works great :D

I run into a problem with netflix, he gives an error code 0013. (I also had this problem with the stock version)

The tip found elsewhere on the internet to delete / rename libdrmdecrypt.so or libomcrypto.so. does not work for me, the files are not found with my root file manager

do you have an idea which file causes this DRM?

thank you !

[MTCD Software Development] miniz98:
I don't have a page that shows that just what you see. It's like it's disabled.
[MTCD Software Development] m3tm3t:
OK. I'm not sure about that, but I read somewhere you may need to tap several times quickly on the MCU version (In your HU perhaps "Model Number" or "Android version" or even "Build number") to check the current MCU version. Please let us know if this worked.

The Instruction is mentioned here.
[MTCD Software Development] amrotota:
thank you

first of all i have to thank you for what you have made

i want to be sure which rom will fit my dvd

model : px3 (1024*600 o)

android : 7.1.2

mucu version : mtcd _ksp_v2.62-1
[MTCD Software Development] m3tm3t:
I reflashed my HU from Hal9k 7.1.2 Nougat ROM to this 5.1.1 LP ROM cause I found that for 1GB ram HUs, Nougat is not suitable ROM since there were some problems with Video encoding and also Waze navigation crash even in 2D mode. now in this ROM, everything is working like a charm. Inbuilt Video app supports MP4 and Waze works even in 3D mod without any crash. Again I recommend for those with

1GB ram

to use this ROM which is faster and smoother than Nougat.
[MTCD Software Development] akslow:
what should be standard in rom:

1) volume level depend on speed (using extra app: RK3066 HeadUnit - google play)

2) autostart of the apps after shut down (using now PCV Startup Builder - Google Play)

3) google speech to text service (with microg works nice Google APP above v.4.1 https://www.apkmirror.com/apk/googl...29-1706998-arm-android-apk-download/download/)

4) option to set lower DPI (Waze GUI has problem with default value)

5) default changed build.prop to enable instalation of TOMTOM from Google Play.

Rest is fine :) THX.
[MTCD Software Development] typos1:
No you dont have an MTCD/E device so you cant use it, sorry.
[MTCD Software Development] Hal9k_:
Disable the Android screen saver in the Display settings, and you will see first of them.

Then you can select another one in the Mod settings.

[MENTION=9120686]amrotota[/MENTION] You need version 2.2.

[MENTION=5911086]akslow[/MENTION] Has written down. I'll think about it.

[MTCD Software Development] Hal9k_:
OTA-package v1.3.1 for Hal9k Mod v1.3 was released.

Added management of third-party applications using the buttons on the steering wheel or on the front panel.

Applications must support media buttons. Tested on PCRadio, MX Player, Poweramp.

Fixed bug with displaying system icons in the statusbar.

Added the ability to disable switching folders in the Music by the buttons on the steering wheel.

Fixed interface display for 800x480 resolution.
[MTCD Software Development] Knightbird68:
Hal9k, I just installed this rom per our instructions, and everything seems great so far!, I even got the OTA update as soon as wifi connected! Excellent work and I thank you! I'll buy you a beer in a bit..

Some notes for others...If connecting to wifi hotspot on your phone, make sure to use 10 digit wpa2 key (with only alpha and numeric keys)

Install your apps from playstore and log into your accounts as needed BEFORE you switch to MicroG, or you may have to switch back to get them configured. I was unable to log into Waze or iHeartRadio until I switched back to Gapps. Once logged in, I switched back to MicroG and everything was fine!

Thanks again! I look forward to being able to use your 7.1 version someday! I have a HotAudio (MTCD_HA) unit with no mSD card slot, so I cannot boot from one to run the 7.1 recovery. :( and system update doesn't recognize the update.img file for 7.1, even when named dupdate.img.
[MTCD Software Development] Hal9k_:
[MENTION=2607485]Knightbird68[/MENTION] Thanks for the feedback and donation.

It will be advisable if you buy a new coreboard with 2 GB of RAM and PX3.

The changes are the same.

There are non as it didn't even get that far, put the card in and went into settings > about > update. A toast pops up saying "incorrect target" and that's all that happens.
[MTCD Software Development] Hal9k_:
is dupdate.img in the root dir of the card ?

Then try through the recovery.
[MTCD Software Development] FlanFlinger:
Yup, on the root of the card and the USB stick, card formatted as fat32 using sd formatter, USB stick formatted to fat32 in Gparted.

Tried to get the recovery up buy booting with reset pressed in and power button held in while turning the ignition on.
[MTCD Software Development] Hal9k_:
Look for a suitable way to boot into the recovery system on the forum.
[MTCD Software Development] FlanFlinger:
Found this on another thread

The trick with power button does not work since on Insignia access to the power radio buttons is via canbus interface. Power button only switches screen on and off when not in Android... nothing more.

So solution:

Is easier if the unit is not mounted in the car, I have not tried to enter recovery after a reset, but maybe I will try sometime.

1. Disconnected all power from the unit... ACC & BAT disconnected

2. Prepared 12V power supply with on negative and two positive connectors

3. Connected negative to GND & one positive to BAT

4. Connected USB keyboard

5. Press right ALT (ALT GR on some keyboards) and PrintScreen

6. Connected the other positive lead to ACC (unit does not work if both BAT and ACC are not connected)
[MTCD Software Development] Hal9k_:
And does it work? With a keyboard?
[MTCD Software Development] FlanFlinger:
Not sure yet, will need to pull it out of dashboard to plug one in, the only external switches that are on the unit and not done through canbus are the reset and a micro sd slot. The rear of the unit is the same as double din ones, 2 USB ports, one marked as for being for 3g.

I'll pull it out with the screen, that should work without canbus because those are separate cables.

If I manage to get it into recovery I should be able to do it in the car, if it does work in the car I'll do some instructions
[MTCD Software Development] FlanFlinger:
Yup, works with the keyboard using the method quoted earlier.

Installed via micro sd as I had the keyboard plugged into the one USB port I'd fitted a lead to (I'll fit another lead and hub later).

OTA not working, tells me there's an update but fails to fetch it
[MTCD Software Development] Hal9k_:
Wow !

Is the internal flash drive accessible ? Does it have the right size ?

Try to reflash again with wipe.
[MTCD Software Development] FlanFlinger:
The SD slot shows as "usb" in recovery, I forgot to factory reset when installing, I'll flash again with a wipe.

This time I'll take a note of the procedure to get into recovery and take some pictures so you can add them to your first post :good:

At least I didn't have to pull the unit out of the dashboard to do it :D

Edit

Factory reset and install with wipe has fixed the OTA
[MTCD Software Development] hugo13sousa:
Dear Hal9k_ , let me just thank you for your work. I've been using your mod for quite some time now, and it is just great.

Yesterday I updated it to v1.3.1 (was in 1.2). Everything works as before (I did a clean install).

Regarding the wheel keys, the volume and change track work, but the other don't... When trying to map the wheel buttons they don't happear...even the ones that work. I press the buttons but nothing happears on the screen to map... Can you help me? ((seat ibiza a-media rk3188 kgl)

[MTCD Software Development] typos1:
Any RK3188/PX3 MTCD/E ROM is compatible with any MTCD/E MCU.

Although you would be better off updating your MCU, thats quite an old one.

I want to congratulate Hal9k for having developed this Rom and for the availability it provides to all of us users. I installed the rom and I find it really beautiful. But I met two problems.

It's strange. The update did not change anything in this regard. Try to reboot the GU by power.

It was fixed in 1.3.1
[MTCD Software Development] chandlerp:
Hi, I have switched back to this ROM as I was having issues with using Radio Player or Spotify with Sygic Navigation. Basically, if I launch Sygic when Spotify or Radio Player are playing, they stop about a minute later and just leave Sygic running.

I thought it was maybe a resource issue with the Nougat ROM so I've come back to Lollipop but the same thing is now happening on Lollipop.

Any advice?

It was suggested to increase the buffer size on the other ROM but the only buffer size I can see to change is the log buffer in developer options.

e2a: I'm using MicroG and I only ever have Sygic and a streaming app running
[MTCD Software Development] mac73:
Hi, I have two problems, if I try to upgrade to version 1.31 via Ota, network error appears and the download does not go on.

I then switched to microG, but the playstore does not work, it appears: "error retrieving information from server [RH-01]".

Thanks for your help.
[MTCD Software Development] chandlerp:
If you switch to MicroG you MUST remove your google account from the accounts screen in settings. Then if you launch the play store you'll be prompted to log in again and it will recreate your account with the MicroG spoofed signature.

[MTCD Software Development] m3tm3t:
Dear [MENTION=5092263]Hal9k_[/MENTION]

This is a feedback about a little issue and that is, I've unchecked the "left back icon" in status bar setting under the mod setting several times and just right-hand side of the status bar shows the back icon, but after a short while, again that turns to checked option and the icon appears in both right and left sides of status bar automatically. It seems the settings would not stay stable in mod setting somehow.
[MTCD Software Development] Hal9k_:
This may be due to an incorrect reboot. Try to reboot the HU from the shutdown menu after changing the settings.
[MTCD Software Development] mac73:
I solved the problem of the play store, but the ota of 1.3.1 still does not work. Is it possible to have the file to be flashed by recovery?

Hey all,

Just want to leave my small observation here.

I noticed this ROM and stock rom works fine, if you don't connect your google account to it. Everytime I connect my google account the device slows dramatically and becomes unresponsive most of the time. MicroG worked wonders, but then I didn't have a working app store.

Now I have gone the route of using this rom, without linking my google account and the software seems very responsive.

Has anyone found a music player better than the stock one, is free and can be downloaded outside of the Google play store?

Alternative Music Player

Hi, you can download Poweramp as an APK from this link https://www.apksum.com/app/poweramp-full-version-unlocker/com.maxmpz.audioplayer.unlock and if you install Carwebguru Launcher or Car Launcher Pro (it probably works with other launchers as well) set Poweramp as the launcher internal player and confifure the launcher to play music on boot. It starts instantly continuing from the last state (last track played). Carwebguru is the launcher I use as it can be configured to do far more than just launch apps and the APK for that is on this link https://apkpure.com/carwebguru-launcher/com.softartstudio.carwebguru/download?from=details, I hope this info helps. :cowboy:

Disable DVC (Direct Volume Control) in Poweramp settings otherwise it doesn't mute during phone calls.

I've got a problem with Google play service update. Every time I start the engine, There is a notification saying Gboard can't run unless you update Google Play service. Having the same notification for VPN master app. I've tried to update the google play service but the installation fails and for troubleshooting, it opens MicroG settings. I have cleared Cache and Data of play store, MicroG setting, and mentioned apps but the problem still remains. Do you have any suggestion?

Now I use the swift keyboard instead of Gboard but it is not about Gboard and is due to play service.
[MTCD Software Development] Hal9k_:

Help plz!

I tried to use this ROM, but i think something went wrong. I'm no expert, so plz any help would be appreciated. I have done this one time before (1 year ago) and it went fine. But now the HU keeps booting up in recovery mode and when selecting "update system/mcu from usb" it says "find and analyze RK image". After 2 minutes it fails with bad block and error -6 messages. Am i missing something? I've (stupidly enough) tries wiping data and all other options. Nothing works. HU keeps booting into recovery mode. Is this HU bricked now?

[MENTION=8882636]Socrates 78[/MENTION] It looks like a corrupted image. Try to write dupdate.img to another SD card.

First, you must install an "other launcher" from the OEM folder in the Installer application.
[MTCD Software Development] Socrates 78:
Thank you for replying. I in fact managed to fix it 30 mins ago after many reboots:)

I updated the MCU to KD_2.40 (previously was 2.39) and then followed your procedure: SScard + USB with Hal android 7 img

Works like a charm now:)

BT audio is better

Keyboard does not lag anymore

System is faster

Google maps is responsive now

Under Android 5.1 this was a PITA

Only downside (this was already so in android 5.1) is radio reception is poor.

Tnx Hal! I'll donate for sure!

Hello everyone!

I recently updated my HXD car radio. It was 5.1.1 so I used this threads firmware. Everything went properly but after the process car radio boots in loop (it's stuck on boot logo) and after two restarts that it does by itself it goes to black screen and turns off. After that point I rebooted it manually by pressing RST button but then nothing happens - just black screen.

I managed to get back to boot logo loop but still nothing happens.

Most problematic fact is that I can't get into recovery mode :/ all described methods I've found leads to nothing.

pressed RST and PWR for 10 secs and then PWR once

pressed PWR for 15 secs, then PWR once more

disconnected from power supply and connected back holding RST with all time combinations

and much more which I've found

RIght now I'm quite desperate :( maybe you could give me some hint what else I could do to revive it?
[MTCD Software Development] Hal9k_:
Try to use bootable SD card.

Did you tried to enter the recovery before update ?
[MTCD Software Development] melvinfox:
In fact I did as I tried with Android 7 Hal9K FW but without luck (it wasn't detecting it as no update image file), probably because of file size.

As I understand correctly the bootable SD will be prioritized than the regular data on the device (so will run instead of regular boot logo screen)?
