Thanks for the awesome Rom! Are you planning to keep this device updated or should be plan upgrading our system :(? You have the best stock experience Rom for px3! Kind regards
[MTCD Software Development] abellemare44:
Step by step upgrade ????

I see that it works for someone, do you have a Step by Step for beginners ??????

thanks
[MTCD Software Development] demetry14:
Download it, put it on a MicroSD, reboot to recovery install, reboot.
[MTCD Software Development] bdomi40:
Salut #abellemare44, je suis français également et je possède un autoradio Seicane avec le processeur PX3 1 Ghz.

Mon autoradio avait la ROM 5.1.1 d'origine. J'y ai mis la ROM de Hal9k 2.3 et le poste fonctionne bien mieux. C'est plus fluide et rapide.
[MTCD Software Development] kabelgleichung:
[MENTION=4406014]abellemare44[/MENTION]: You are really annoying, asking the same question multiple times in two threads. As stated in a post before, the instructions are in the first post ("How to install the firmware ?"). If you are overchallenged with copying a file to an SD-card, this project might not be a good idea for you.
[MTCD Software Development] Eric_Ca:
Hi guys, I have a small issue with the HU. I installed Hal9k's rom V2.3, almost everything works like a charm, but I can't find the Bluetooth toggle in setting or other places. I could not even turn off Bluetooth using other apps. The Bluetooth stays on forever. Is there anyone else having the same issue? I just want to find a way to toggle Bluetooth. Any thoughts, guys? Thanks!

[MTCD Software Development] kabelgleichung:
I don't think it's possible to disable bluetooth. I was also looking for that switch, but haven't seen this option in any other ROM either.
[MTCD Software Development] abellemare44:
I have the version:

PX3-userdebug 7 1 2 nhg47l eng hct 20180228 105844 test-keys

Nothing says RK3188 is it ok ?

Thanks
[MTCD Software Development] demetry14:
Set Bluetooth to NO in Factory Settings maybe?
[MTCD Software Development] abellemare44:
Did you have all the software that you must have for your car to set parameters etc... after the upgrade ?

thanks
[MTCD Software Development] echudoba:
Hal9k - Could you add a 10mph to the volume at speed. I know you added 20mph. I found that stepping up 1 at each increase works really well and smooth and I must have a noisy car, it would help to start sooner.
[MTCD Software Development] meazz1:
where is this feature in 7.1.2 rom.

I know he added this on his 8.0 rom.

My 7. 1.2 rom is solid as rock except I'm missing this auto volume adjust feature :(
[MTCD Software Development] echudoba:
Sorry, somehow got it in the wrong thread. I have the 8.0 rom.
[MTCD Software Development] Hal9k_:
Hi everybody ! :)

Version 2.4 released

List of changes in the first post. Screenshots in the third.
[MTCD Software Development] meazz1:
Bro Bro Bro I wanna hug you :):):):):):)

Do I need to wipe data if coming from 2.3 to 2.4 or just install over 2.3?

More donation sent ( always wanted the speed dependent volume control).
[MTCD Software Development] Hal9k_:
Thank you ! :highfive:

In general, wipe data is not required if you have not used microG
[MTCD Software Development] mariuscov:
Can I update over OTA if already I have installed 2.3?
[MTCD Software Development] Hal9k_:
I did not make an OTA package, because this version is based on a new base firmware, which is made in img format. You can install it from a flash drive from Settings or from recovery. Without wipe data.
[MTCD Software Development] iMattmax:
Works fine, thanks
[MTCD Software Development] bladehu2:
My HU stuck at boot logo (after first reboot) more than half hour... I updated from 2.3 without microg so I didn't select wipe data. My mcu fw is the latest mtce lm 3.01c. How much time should I wait? Or better to go into recovery and do a factory reset? If I remember right the 2.3 update from 2.2 wasn't longer than 20mins.

---------- Post added at 04:03 PM ---------- Previous post was at 03:26 PM ----------

I did a factory reset from recovery, now it works fine. Maybe there are too much changes in new fw and the wipe is always needed not just if you are using microg.
[MTCD Software Development] abellemare44:
I have installed V2.3 and everything is working very well. Thanks

The file on my USB stick was that version !!

I'll install v2.4 this afternoon!!
[MTCD Software Development] mariuscov:
Thank you for your work!

Like in the previous version I have an issue that consist in DVR doesn't work. The program starts and appears on the screen the image from the camera but when I touch the button to start recording the program closes.

Could be a MCU issue?
[MTCD Software Development] Hal9k_:
Now it is difficult to say.

I checked the installation without wipe on top of the newly installed version 2.3. It worked.

Hardly. Rather, the problem is in the camera. Try another one.
[MTCD Software Development] jmd1213:
Thanks for your work!!! I've never been able to get my bluetooth working on my HU. Figured I would install this. Still no bluetooth but everything else is working. Is there something I'm missing? Does the mcu file have something to do with my issue? Thanks again for the rom!!! My MCU version is MTCD_KLD_V2.60b_1

Aug 21 2017
[MTCD Software Development] meazz1:
Ok, I installed w/o wipe and everything seems to be working thou I have not driven the car yet.

One question, can I make the volume transparent or not shown on screen when it goes up or down?
[MTCD Software Development] abellemare44:
I have installed 2.4 and everything le working but I think that he's slower than v2.3, am I thé only to remark that ?

I'll wait few days and maybe I will reinstalled v2.3 is it possible to install over 2.4?

---------- Post added at 12:53 PM ---------- Previous post was at 12:38 PM ----------

Is it possible to change the home page, I would like to have speed on home page ?
[MTCD Software Development] Hal9k_:
Show me dmesg output

type in the terminal app:

su
dmesg >/sdcard/file

and copy "file" flie from the internal memory

I could not think of something like that. :D

You can decrease "Display timeout" in the Mod settings.

The system needs time to update and odex all applications.

In addition, we now have a Magisk.

I have not tried. With a wipe - of course.

Is your current PX3 v2.4 rom for Rock chip compatible for the Allwinner T3 chip type too?
[MTCD Software Development] Hal9k_:
No access. I've sent a request.

Of course not.

Why did you decide that?
[MTCD Software Development] gisigisi:
Is there an option to choose colors such as the old version for radio app and bluetooth app?

Can you post some some screent shots for the radio app and bluetooth app?
[MTCD Software Development] Hal9k_:
[MENTION=6210507]gisigisi[/MENTION] If you mean skins, as in v1.x, then they are only in that version, since their author made them only for Android 5.

Screenshots of radio, music and bluetooth are in the first post.

Problems with install rom with recovery

I have used the toolkit to install the image file to an sd card and usb and insert it to the gps slot. I opened the recovery menu and select install image from sd. Then i get an error. Can not find firmware image or invalid image. What do i wrong? Do i need to select clear all? I hope i can get the android 7 work on my car android radio its an rk3188 1024x800 s edition. Thank you
[MTCD Software Development] meazz1:
Post a pic of your MCU file.

You need to extract the zip and copy the .img file to the root of an usb or sdcard formatted to fat32.

If you have the usb connected you should get a prompt to update, no need to go to recovery.

Another question, what firmware are you running now, 7.1.2 or 5.1?

If you have 5.1, the process is different.
[MTCD Software Development] bas94:
I have 5.1 but the second post doenst work to me what do i need to do?
[MTCD Software Development] elfrawg:
I also needed many attempts to update from 5.1. I had 2 different root causes why it was not working

- outdated MCU -> update to a recent version, you can experiment with MCUs from other vendors, they are almost identical

- verify written data on SD card (I think there was a checkbox in the SD writing tool). Sometimes the data on the SD card is just corrupted
[MTCD Software Development] mariuscov:
I am able to take photos but when I touch to record video the DVR program it closes. I think the camera is not the problem. What other DVR program can I use? Ani idea?
[MTCD Software Development] TetsuyaTsurugi:
hi, is possible change default radio App or skin, if possible link for download app please ?
[MTCD Software Development] wilfred.simoes:

Thanks for the reply.

Will check out the 2.4 on my device though.

Doesnt work to update system

I have tried to install this mcu software update but my system doesn't see the file as an update. I extracted the file to a FAT32 SD card of 8gb and then put it in my gps slot. But the system won't open it as update and when i scroll to the settings of the system update he didn't see anything like an update. I am using android 5.1 now and will upgrading to 7.1 but that didn't work either. I have a MTCD KD v1.82 software right now. I hope you can help me. Thank you

[MENTION=5092263]Hal9k_[/MENTION] i have install update on my px3 ad work good, is possible change skin to radio app ?
[MTCD Software Development] Hal9k_:
[MENTION=5374821]TetsuyaTsurugi[/MENTION] There are no other designs for the radio. But they can be, if you draw them.
[MTCD Software Development] abellemare44:
Maybe someone else have these problems:

- Bluetooth not connecting to my phone (About 1 time out of 8 or 9 restart) not a big big problem I have to restart the car or restart the Radio and it will connect

- When I start the car, if I was playing music with Google PLy Music or Youtube Music when I shut off the car the player is playing with no sound, I have to play Pause wait 10 seconds and Play again and there is sound!

- GPS Time Setings: I can't use the AUTO for the Time Zone from the GPS, I have to enter New York as Time Zone and the Time is OK

Thanks

It's not related to version 2.4, with the stock firmware these problems where there and MCU V2.80 at the start and now the MCU V 2.94 and the problems are still there
[MTCD Software Development] iMattmax:
Now, after a while of using 2.4 I have found a little bug. The rns show me that the bonnet is open, but the car diplay didn't show me that or in other words it's definitely closed.
[MTCD Software Development] TetsuyaTsurugi:
[MENTION=5092263]Hal9k_[/MENTION] it's not a problem for me to work with graphics if is possible and you tell me which files I need to edit or if there is a guide I could create something
[MTCD Software Development] yellowbox:
Can the screensaver be fixed for 480dpi screens?

Also the mtcdialer is stuck on connecting to bluetooth service.
[MTCD Software Development] bladehu2:
Same by me. If I stop the car and open the drivers door it shows for a short time the bonnet with red. I'm not sure it is android bug as these stuffs (car status, AC) are handled by mcu. Have you also updated mcu to 3.01c?
[MTCD Software Development] nosidefcp:
hi guys. i have a 2/3 delay in bluetooth voice when receiving calls. any way to fix it?
[MTCD Software Development] Hal9k_:
Such a function is simply not there and has never been in the GU.

What is the CanBus type number in your factory settings?

If you are ready to make a cool design for a group of stock applications (which I will like :) ), then I can give you deodexed applications for editing.

Yes. This will be fixed in the next update.

I can not confirm this. At this moment it is trying to download contacts from the phone. Maybe it can't do it with your phone.
[MTCD Software Development] txemikal87:
Hi everybody!

I have just bought an MTCE PX30 unit from the Isudar Manufacturer.

It comes with Android 8.1.0 and I don't find any rom for this Model-Android combination.

Works this ROM coming from an Android 8.1?

Thanks in advance.

I keep getting the error when switching to microg. As soon as I select microg, the system reboots and then comes up to the recovery screen with this error. I have tried wiping cache, partition, etc. I have also re-downloaded the hal9k rom and reinstalled from scratch. Everytime I keep getting this error when switching to microg.

Id stay on N if we can get viper working but the room is missing audio_effects config file altogether. It's also missing the audio mods from 1.2

I'm really confused why hal9k hasn't even bothered to check in with us given the massive amount of activity on this thread
[MTCD Software Development] typos1:
Well howdy !

You have a Klyde (KLD) unit (pretty certain KDL is a mis-type).

There are updates yes, theres an MCU thread and - stupidly - about 5 MM RK3368/PX5 threads with MCUs in too, the latest KLD is about v2.7X and now theyre now called "MTCDE" rather than MTCD.

---------- Post added at 07:36 PM ---------- Previous post was at 07:34 PM ----------

Shame, maybe you can ask [MENTION=5092263]Hal9k_[/MENTION] to add it ? Standard N ROMs have some sort of screen lock, cant you find that ?

Tried putting the audio mods form L on N ?

I guess hes busy and will reply when he can.
[MTCD Software Development] masri1987:
yeah the built in audio mods from his 1.2 mod rom isn't on his mod 2.0 rom

I'm just disappointed he hasn't even bothered to check in. Many people are having problems downgrading, and your head unit is completely not even booting. We desperately need some guidance as doing the same thing we did for N for L isn't working whatsoever and there's zero explanation as to why

---------- Post added at 09:09 PM ---------- Previous post was at 08:57 PM ----------

i could workaround my current issues if there's a way to get Magisk working instead of supersu, has anyone been successful in doing so?
[MTCD Software Development] xtcr1st1:
Thanks [MENTION=456516]typos1[/MENTION]. I checked some way to lock my unit but didn't find it. [MENTION=5092263]Hal9k_[/MENTION] can you please add the lock screen feature back. Thanks
[MTCD Software Development] typos1:
My head unit is not booting because I am in the middle of doing something to it and I havent got around to finishing it yet

Apart from that as far as I can see its only you having the problem (although I realise that doesnt help you with your problem).

He does it for free and as with all devs theres no guarantee about anything (I realise this doesnt help you either).

He could be working or away or something, he cant be on here all the time, if he wanted he could never ever login ever again.

I know its frustrating but you just gotta have patience.

Why dont you try finding the audio mods form L onto N while youre waiting ?
[MTCD Software Development] masri1987:
I didn't want to mention that i donated for 1.2 because it shouldn't matter (don't want to differentiate between those who donate and those who don't because we are all one community)

Forgive me if i'm making a bigg fuss about all of this. I'll try to take a break.

If i'm the only one with the problem, can you tell me how you would downgrade if it was you? Because i'm open to accepting that i am doing something wrong aka user-error lol

How do I "find" those audio mods? It's not in sound settings in the rom...

I'm trying to be patient, gonna try to do magisk root instead of supersu... that way i can use viper4audio magisk module instead of the app itself.
[MTCD Software Development] Hazard15301:
Are you trying to just get Viper4Android installed? I read back through your previous posts, but you just said the audio mods from L were missing from N, and you didn't go into much detail about your issue.

https://xdaforums.com/showthread.php?t=2191223

You want to download the Viper4Android FX 2.5.0.5 apk, install that on your head unit. Open the application and it will prompt you to install the V4A driver. Reboot and you're done.
[MTCD Software Development] typos1:
If it was me I d wipe data/cache lots, if it still didnt work I d think it was a partitioning error and seek help on how to re-partition. Mind you if it was me I d forget about viper and do the 7floor audio mod, its way better than viper.

Not sure where to look for the audio mods TBH, it sounded like you knew the way you were talking !

Trying Magisk sound like a plan, but surely it just automates what you were trying to do manually ?

Hes tried viper and it doesnt work.
[MTCD Software Development] TvBIFI:
Finally i got it working

1st Flashing i had those symptoms like above

2nd Flashing MicroG installs after Stoping Playstore App but TomTom and Titanium Backup are crashing at execution

3rd Flashing first installed TomTom then MicroG after stoping Playstore App but Tomtom and Playstore get no access to internet.

4rth and Final Flash The First thing ive done Stop Playstore and Install MicroG. After 2 Reboots and setting up the Playstore it gives me an RH-01 Error

Now ive got to delete the Google Account and add it again.

Playstore now have connection and Installed TomTom. as i saw the Traffic warnings i was happy.

This Update process took me 12 hours inside the Car
[MTCD Software Development] masri1987:
Yeah Hazard as typos said i tried that and it gives me I\O error because the audio_effects config file in vendor/etc and system doesn't exist (where in 5.1.1 1.2 mod rom it did )

Typos, i meant the audio mods that were built in the 1.2 mod rom from 5.1.1 , i could live with those and not have to be urgent with V4a .

I have a feeling it's partitioning issue as well, but does that explain why it doesn't even recognize dupdate.img loaded on the sd card as valid system image file?

Can't do the audio mod with the hardware because i don't have the tools, but it's on my to do list once i gain full employment again..

I'm gonna do the magisk route and report back
[MTCD Software Development] typos1:
Why dont you google where the audio_effects config file is in Android 7 ?
[MTCD Software Development] BlinkyTrojan:
Flashing this was easy. I am currently running this without facing any issue (yet).

Although I have not properly tested microg yet and installing apps from Gplay.

So far the stock apps are running smoothly, switching is fast - RAM usage is at 680MB, and i have soldered 2GB chips from group buy 2.
