[MENTION=472138]hal9k[/MENTION] did you think about improving FM radio app with background station search? I know that there is only one hardware FM tuner but two are needed for this (like the high end MB or Audi radios, wich updates continuously the FM stations being received while you continue hearing the one you selected; an example pic is attached). In any case I think that there is one workaround:

Get the GPS location.

Send the right request to https://fmscan.org, including location.

You get the results with FM stations being received in your position.

Parse the results and update radio memory stations or some kind of new list of stations being received realtime.

Repeat each 5 minuts or so and enjoy.

Of course data connection is needed. I tried here in Spain with my location and it works quite well.

Regards.

If I install the rom with the frond sd card instead of the usb, will it be much much longer and are the steps extacly the same as with the usb?
[MTCD Software Development] bobodaclownster:
Yes I just did the manual down load, Unpacked the file to the micro SD card and followed the steps in post 1. My unit took about 5 mins to validate file and maybe 10 to instal. Wasn't disappointed with the upgrade.
[MTCD Software Development] kirildaskalov:
I have the same problem. Factory reset and V4A will be preinstalled.
[MTCD Software Development] Jkteam:
Hello thank you

Do I need a dedicated sd card or I can just put the files on the one I am already using that has other stuff like map pictures etc?
[MTCD Software Development] digitalcan:
I can confirm that sound is not good on 3.1, 3.0 was great.

No viper installed. Sound is not clear right now...

Also when i launch a2dp app to listen bluetooth music. There is very low sound from radio app very low sound there is a interference with the radio module i guess with 3.1 update :/
[MTCD Software Development] bobodaclownster:
Doesn't need to be dedicated.

[MENTION=5092263]Hal9k_[/MENTION] Best firmware for my mtce xcr. One question: it's possible to install a patched sound mod or the amplified apk with more frequency? Like wadzio mod?
[MTCD Software Development] marchnz:
Yes, of course.
[MTCD Software Development] dgcruzing:
Also confirmed working fine with sound patched MCU..

Don't know why others are having problems but 3.1 with patched MCU HU 2.95_1 working fine with Boss speaker system in mine..

Sound is same as before the flash..

Which I can say with the above setup is 100+% better then stock MCU 1.8* it came with..

Viper mixer is working on mine too.

Not sure when I got it on..but seem to recall I put it after I installed the sound patched MCU..

If you are having sound problems why not try reflashing a soundmod MCU to see if there is any difference.. ??

Maybe a better way would to have a stock MCU and a sound patched MCU to run the tests with..

Then report back..

as while you are dropping into the thread that you have upgraded to 3.1 and you are having sound degrades.. you need to run a few more tests before putting blame on the Rom..
[MTCD Software Development] digitalcan:
I updated to the latest mcu. Nothing changed :/ bluetooth interference with radio app is very annoying

Mod version: hal9k mod 3.1

Mcu version: mtce_mx_v2.96

I can try the soundpatched version of the mcu for mx units? İs there a link for that file? How can i find this?

Thanks

Dear Hal9k_,

Thank you for this wonderful XMAS Gift "Hal9k ROM 3.1"! Works like a charm.

I only have one issue which I'm not sure if it is hardware or ROM related.

When I try to change "CAR / MOD Settings / Manage Applications / List of Applications that are switched by the Mode button" settings It doesn't matter what I select or deselect. The HU doesn't care about it. Sometimes it accepts the addition of i. e. Google Assistant but keep switching all the other default apps even if they are deselected. The other times I deselect all default app and add one, but the HU ist still switching between all default apps.

I've installed this unit in my wife's little lion cabriolet: https://androidautoshop.com/peugeot/363-2514-peugeot-207-207cc-2007-2014-9-touch.html#/26-map-europe

Mode switch is done by the car's mode button which is not part of the head unit.

Do you have any hint on how to fix that. Maybe this are only missing write permissions somewhere? Well, I don't really know anything about that. :)

Thanks.

Backup and Recovery of Stock ROM

Hello,

I`m new here and I did not flash my Pumpkin AE0373B-01A with Hal9k already. I`m still collecting information.

At first many thanks for the community to make hal9k and all the support. That's amazing.

In the youtube video "MTCD(E) PX5 How to install Hal9k Mod v3 over Android 8" I did not found an option to backup stock rom before flash HAL9K. How can I do this? I would like to make a backup to be able to restore Stock Rom in case of any issue or in case I have to send back the HU to pumpkin during warrenty period. I don't like to loose warranty.

I have checked the whole thread but did not found an answer. But maybe I did not read carefully enough.

Thanks for your reply.
[MTCD Software Development] digitalcan:
Hi,

I would like to sum up my last trys:

I tried latest MCU for MX headunits v.2.96 and soundpatched version 2.96sp.

I tested with a 320 kbps mp3 with stock music player with amplifier in flat mode. My sound is not clear it is very deep right now. Before with 3.0 I really don't have any problems.

Viper is off and drivers are not installed.

Also I am receiving low volume noise from radio app when i launch a2dp program for listenin bluetooth music.

I'have updated to 3.1 OTA without wiping my disk.

Is there a solution or can i revert back to 3.0 version of the mod without any problem ?

I cannot figure out what's wrong :/

Thanks
[MTCD Software Development] Garfanki:
Good afternoon and merry Christmas to all, a stupid question: I use the 3.1 version of this ROM and I want to know if there is a way to speed up the boot... Thanks again!
[MTCD Software Development] Doctor_90:
Do you try to downgrade MCU ? I had same problem with my old PX3, and downgrade had improve sound.
[MTCD Software Development] ntomazn:
Not work for me change widget. Video pleeas!

41. Android 8 does not allow third-party applications to automatically create widgets.

Therefore, if there is a desire to install widgets from some launcher, we do this:

Delete /system/app/HCTwidgetHA and reboot the HU.

We put APK widgets and launcher. Add any widget and give permission (see screenshot).

Then remove the launcher and install it again. Or clear the launcher's data.

How to? I have mtce xrc 2.93_1 firmware and hal9000 3.1 rom. Thanks
[MTCD Software Development] Hal9k_:
Interesting idea. But there is a problem with the fullness of the database.

I found in it all the stations that broadcast in my city, but not all stations are listed for the neighboring city.

I did not notice this.

I haven't tried it, but I think yes.

[MENTION=1903543]EwaldB[/MENTION]

Not all third-party applications are good to include in this list.

Try to include only two positions in it: the stock Radio and Music.

Then gradually add other applications if everything works as it should.

It is necessary to close the list editing screen before pressing the Mode button.

Usually this is not required. It is much easier to ask for stock ROM from the seller or find on this forum.

Thanks Hal9k_, for your quick reply. I will contact seller pumpkin.

Just one question. The HU of Pumpkin is using canbus to switch on/off automatically when put in/put out the ignition key. That is great. Button the original HU can be switched on by pressing power button while ignition key is still put out. In other words can I startup the HU without put in the ignition key with Hal9k rom?

Thanks for your reply. Holger
[MTCD Software Development] kare_meesner:
Hi Hal,

your ROM is great, just one question: is it possible to get the informations from Real Zoulous DAB-Z (DAB-Radio) like track or interpret on the new screensaver?

E.G. the FCC Car Launcher shows this Informations, so they would be present.
[MTCD Software Development] Clandaries:
I have installed Version 3.1 on my testradio in my office and all went well.

Now i have installed it over version 3.0 in my car and it killed the Android system.

I had to wipe all data.... I hate this....

I have done backups with Huawei Backup that worked nicely but now i cant install this app.

Can someone confirm that it is not possible to install Huawei Backup? And then it would be great to know why not.

[MTCD Software Development] Hal9k_:
Read #40 in the List of changes.

You can call from android auto through mtcdialler with the help of Ok, Google.

I trying to avoid wipe user data.

In addition, small changes will be installed through OTA.

A full package will be made when changing the version of the basic firmware.

But even then, most likely, wipe will not be needed.

Earlier in my car was installed px3 board and my firmware, of course.

Several versions were installed in a row, including intermediate versions.

Wipe has not been made since the moment of purchase.

Maybe you should pay attention viper4android developers on this?

I chose this version precisely because it is easily installed using Magisk.

[MENTION=5268316]michael08071984[/MENTION]

Android Auto

Well the android auto now support “self” mode (so you can install its apk from e.g. apkmirror, and it will use maps/waze, google play music/Spotify/etc installed on your head unit as if it were a phone plugged into it. I am not sure that this apk can even support android auto usb connection - for that you need separate dongle that you can buy from e.g. aliexpress. Me, I just happen to like the clean and uniform UI that it provides - so I can use the head unit through its interface.... if it only could dial (and support built-in radio) it would be the best interface for me.

Hi there

Today I did an OTA update to v3.0.1.

Now he still finds a new OTA update with 1301MB? Is there something new released?
[MTCD Software Development] xLeviNx:
Read the first post
[MTCD Software Development] Shadow128:
And which part did you excactly mean? I read it, but found nothing on that behaviour after OTA update
[MTCD Software Development] EwaldB:
.

Thanks for your reply. Unfortunately that did not work for me (by the way, I want to avoid stock radio because DAB is the much better solution for me. Unfortunately Mode Button insists to use stock radio :-/ )

With stock rom the mode button switches between stock radio, stock musik player, A2DP, AVIN etc. Same with your ROM and default settings.

When I change the list, it sometime works for only one or two times or it does not work at all and than came back to default settings without changing the apps shown in Mods overview.

It doesn't matter if there are apps included or not. Mode button always switch between the apps/line inputs named before. Maybe the Head Units settings are ignored because the signal to switch is sent by CAN Bus and not by the head unit itself? I don't know. Would be fine if you will find a possible solution in a later version of your ROM.

However: I'm very satisfied with this ROM
[MTCD Software Development] xLeviNx:
Right after where it says Version 3.1 and what’s included in the update. Since you’re doing an OTA, he stated there is two updates. Second one being the actual update with the upgrades that he’s listed in the first post. Read the thread, all your answers are listed here.

Hi [MENTION=472138]hal9k[/MENTION]

I started to play with canbus key remapping and noticed one problem.

I have an Alfa Romeo 159 wich has up-down-left-right arrows among other SWC keys.

I can remap left-right keys but I can't find the keycodes for the up-down keys. I get the keycodes 260 and 263 wich are not present in the listing, so no possibility to remap them.

Originally left-right and up-down keys were doing the same action (next/prev FM radio preset or music track) so it would be great to assign up-down keys to up-search and down-search.

Is it any file wich I could edit to add the missing keycodes?

Regards.
[MTCD Software Development] SkyBeam2048:
I believe this is not ROM related.

When the ignition is off (0V on ignition line) the head unit shuts down. I belive also the MCU controlling the buttons might be off then. So there is no possibility to act on any keypresses. In best case the MCU would still be powered allowing to act on keypresses. But this would likely lead to some increased power consumption. Long story short: There is likely nothing the ROM could do about this as the buttons are not active.

However there is a possibility to turn on your HU if ignition is off. You need to do some re-wiring and add a button/switch to power the ignition line of your HU with a permanent 12V line from your car. This way you could turn on your HU even if ignition is off. However remember that you should not forget to turn it off then or it will run down your battery. The best option might be to use a simple timer module and a push-button along with a simple car relais. So when you press the button it will switch on the delay module and trigger the relais to power the ignition line of the HU with 12V. After a timeout it will fall-back and connect the real car ignition line to the HU ignition line. This would be similar to most OEM units which allow you to turn it on with no ignition enabled but they will auto-power-off after ~30 minutes.

[MTCD Software Development] Hal9k_:
I think that the application should behave correctly in the OS, and not the OS should adapt to the application.

Poweramp behaves as if there is no other player besides it.

HU is switched on in the case of supplying 12V voltage to the ACC wire. It does not depend on the firmware.

I'll see what i can do. The bad thing is that we do not have DAB broadcasting and I can not check it.

What did you change in system partitions in version 3.0?

[MENTION=1903543]EwaldB[/MENTION]

260 is arrow up and 263 is arrow left.

This is a bug which has affected many other android headunit owners, including myself. If you're on Hal9k's 3.1 ROM then he has integrated B-Max's fix for this in the settings which just needs to be enabled. This didn't work for me but fortunately I had already solved the problem on my GS headunit by creating a Tasker action which resets just the Wi-Fi adaptor, not the USB hub. I posted a link about this a few pages back if you need it.

I've made a mistake. I tried to update Magisk with the latest version in order to have YouTube Vanced. But after reboot, the device is stuck on the recovery menu. When I try to reboot system, I go back directly to recovery.

Cas I just insert a USB key with the original "update.zip" file and again, select the menu item "Apply update system" - "From usb storage"

Or should I use the "Hal9k_Mod_3.x_Android_6.0_upgrade.rar" archive & method ?

Hope to solve this problem :)
