I have had it with all roms and different mcu's and never found out why.

luckily my HU goes to sleep when ignition is off and when it wakes up keeps the stations, only loses them when I reboot the unit
[MTCD Software Development] psyko_chewbacca:
Hi,

There's an issue that has been mildly bugging me since I have had my Android Head Unit. Just wondering if I'm the only one or if this is a known issue.

Sometime when starting the car and the Head Unit powers up, the bluetooth and Wifi radios are not working. My phone cannot connect via bluetooth and the Wifi activation slider in the Wifi Setting menu will not move to the "activated" position.

Originally, a full system restart fixed the issue but now, I regularly need to reboot multiple times in a row to fix it! I found that the best way to quickly resolve it is to reboot in Recovery and then reboot normally (Maybe Hal9K reboot button does not fully power cycle the unit as it seems to be done in Malaysk's ROM?

This issue has been going on since I have had the unit. I didn't stay on stock ROM for long as I moved to Malaysk first and now using Hal9k ROM. Both ROMs exhibit the same issue. Point is I don't know if the stock ROM had this issue. But it seems that when using Hal9k mod, a single reboot doesn't resolve the issue.

Head Unit is equipped with a MD725 version 1 radio module.

MCU is MTCE-XRC 2.89.

Does somebody have a workaround (other than rebooting)?

Thanks!

I added Tasker and Twilight to the white list and checked the current draw. May have added 1ma. Mine draws between 2.5 and 4 ma on standby.
[MTCD Software Development] TT_Vert:
Wow that's crazy low. Does your unit have fast boot or a time defined sleep? (30 mins, 1hr 2hr, 4hr I think it was) in the microntek MCU?

Anyone managed to install a magisk module yet? I attempted to install Youtube Vanced and got an error saying I need Magisk 15 or higher :(

The magisk repository for this module seems to have disappeared, so it's just a version copied over from my OnePlus 5T
[MTCD Software Development] Hal9k_:
Therefore, I store important files on an external SD card and in the cloud. In the phone too. ;)

Will have to install that Blitzer.de...

[MTCD Software Development] Lum_UK:
Yeah, not you're fault at all, apologies if it came across that way. Your ROM is amazing BTW, it's the best my stereo has been in the few months I've had it.

The stock recovery on this thing feels like the Gingerbread days, I'm so used to modern ones, so it took me by surprise when it wiped internal storage as well. Ahh well, lesson learned. It's pretty much all back up and running now anyway.
[MTCD Software Development] scorillo_ro:
Have you ever disassembled your unit as by removing and putting back the Android SOM on the MCU board?

If yes, then your problems can be caused by bad connectivity on some pins. I had this problem with WiFi pins that I resolved by gently bending them out then reinserting the SOM.

You can read this thread to identify the pins: https://xdaforums.com/android-auto/mtcd-discussion-questions-development/px5-stuck-bootloop-t3635412

74,75 are for WiFi

26,27 are for Bluetooth
[MTCD Software Development] gernoob33:
hal9k, thank you for your great work.

I have installed your ROM mainly because

"19.Radio - the running RDS text has been removed from the saved stations buttons. Now we can assign names to saved stations."

After testing the RDS-Text is still running on the station buttons...

I also noted a tiny detail: On some station buttons the sign for frequenzy is changed from MHz to KHz after saving the station name...

What I am doing wrong?
[MTCD Software Development] verszipo:
I'm still on the stock firmware, and i have the exact same problem. I also have an MTCE_XRC unit (V2.89_1) so it might be a problem with the XRC series.

As you said, the only solution that seems to work to get the WiFi/BT to work is to reboot the device a few times and at one point it starts working.

P.S. i haven't opened my unit, didn't do any mods to it yet so it seems it's a factory problem.

I'm want to install Hal9k when i get enough time to be able to tinker with the HU.
[MTCD Software Development] wanze2001:
Hello Hal9k,

Meanwhile, the Rome is running really well, Blitzer.de can start automatically when man first knows how ;)

What I noticed today but that I can not dial the phone number from the contacts, in the dialer app I can search for contact and he is also displayed to me but also here I can not call by clicking the participant.

Is that only for me that way? or a bug?

But what works well is the voice input of the MTCD dialer!
[MTCD Software Development] psyko_chewbacca:
Unit have never been disassembled. Thanks for the suggestion but I prefer not opening it while it's still under warranty.

Good to know I'm not the only one having this issue.

I may try to downgrade the MCU version see if it could fix something but I'm not sure if MCU has anything to do with enabling disabling Wifi/Bluetooth.

Is the MCU responsible of controlling some sort of Wake/Sleep pin on the BT/Wifi module?

I might also try to dig out any init script that is in charge of enabling wifi, see running it manually changes anything.
[MTCD Software Development] pogueoi:
Thank you Hal9k for this awesome ROM. It is really great.

I have two questions:

1. In the settings one can customize the status bar. When i enable "temperature" it doesn't show up in the status bar. Is this an individual or a general issue?

2. When I want to connect another Bluetooth device than a Smartphone or an ODB the BT device shows up in the list but won't connect. I had this problem also with the stock ROM. I wanred to connect a bluetooth media button. It appears in the list but you can't connect it. Do you know any solution for this problem?

Thank you for answering and again thanks for your great work.

Good evening, even the audio of bluetooth calls is bad ... who can help me? are there any configurations to change? people do not hear me or they hear my voice jerky. help!
[MTCD Software Development] maxiauer:
Thanks a lot for this rom [MENTION=5092263]Hal9k_[/MENTION] !!!

I was looking around for a ROM that would allow to edit the list of apps for the MODE button without having to install XPosed or MTCUtils.

But now that I/ ve found it, I see that HA/Dasaita has just launched an updated to the room. Do you have any idea / plan to integrate that on your ROM?

Don't get me wrong. I know this is a hobby for you and I appreciate that you share the fruit of your work. But, if possible, I'd like to avoid spending time on re-factoring my unit with your current ROM, to find a new release a couple of weeks later on...

What can I say, I suppose I'm a lazy guy :)

Using ppp widget 3, I was able to get the 4gdong001 and an e5573 to connect via USB (instead of wifi), but it only connects as a network device (the <-> arrow icon) instead of cellular

While the network connection section is in settings, it doesn't allow setting changes

I also tried a generic 3g usb, but same result as above

Otherwise wifi works ok as an option, just can't see the signal quality of the usb device (obviously)
[MTCD Software Development] vossibaerUAE:
just installed the ROM which looks good. but whenever I try to change settings in the menu of MOD settings I receive a popup MOD setting was denied Superuser rights.... any idea what I forgot to get full access?
[MTCD Software Development] DJorgio:
Try opening Magisk, then the superuser module and turn HAL Mod back on, it happened to me once for some reason

---------- Post added at 11:34 AM ---------- Previous post was at 11:27 AM ----------

1 - This is the same for me, I never got the temp to display in the status bar

2- This has always been the case with MTC devices, the BT module is in the MCU and has been designed to not connect to any other BT device other than smartphone or OBD, connecting to a BT speaker would be awesome, not really sure the reasons behind this though.
[MTCD Software Development] typos1:
Try MTCDtelephony Bridge (attached below).

Not possible, there are 2 resolutions on MTCB/C/D/E units - 800x480 or 1024x600, the only way to change it is by buying a new LCD.

Wiping data/factory reset ALWAYS deletes data - the clue is in the "wipe data" bit !!

[MTCD Software Development] typos1:
Be careful.
[MTCD Software Development] wanze2001:
Now I have tested a few days and must find that the apps in the White List not always reliably start it was blitzer.de or PCradio although they were turned off.

Is it possibly that I have disconnected the acc connection?

Say the radio then completely down drives? If so, a reliable solution would be needed. In the Malaysian Rom I had solved it MTCD, but probably not here.

I have another problem which probably has nothing to do with Rome. My picture of the original vw tiguan rfk is really bad that means out of focus dark and light stripes. I suspect that it is the adapter that connects the original RFK with the radio. Which adapters do you use and have good experience?

I already had a 2 but it was even worse.
[MTCD Software Development] tsavman:
This worked.

Dropping DPI from 240 to 220 revealed the missing app parts that I couldn't see before.
[MTCD Software Development] Hal9k_:
Can not be. Show the video.

It works for me.

This must be supported by the CAN bus adapter.

Installing a new factory firmware does not require clearing user data. I'm trying to do the same. In the future you will be able to install 3.1 over 3.0

The White List does not restart anything.

Applications included in the white list do not close during the transition of the HU to sleep mode, which occurs when the ACC wire is disconnected.

Another thing is if the system restarts completely. In this case, the application startup should be provided by its author.
[MTCD Software Development] Hal9k_:
double. again. :(
[MTCD Software Development] marchnz:
If only people read, took time to understand instead of wasting your time.

The expectation from developers to provide such constant support for simple things must be a source of frustration for many and possibly put them off of developing.

Read up, this is not an issue isolated to this ROM.

Who can help; you can by investigating the issue instead, listing what you have found, tried and recoded, before calling "help".

Dear Marchnz, for me it is not an isolated problem because before, with other ROMs, I did not have this kind of problem; so before commenting better informed and if you do not want to help me do not write me thanks!
[MTCD Software Development] Lum_UK:
Not /always/. The last phone I owned that did that was a Droid 4! My old Oppo N3 and R9S, my GF's old R5S, and our OnePlus 5 & 5T all leave the user files intact when you do a wipe, even on stock recovery. So just wanted to warn folk who are used to more modern recoveries that these MTC units still do it the old fashioned way.

DId this ever get resolved? I'm having a bear of a time getting youtube vanced installed. It's no longer in magiks repo so I was trying to manually install using plz files but getting that same v15 error. I've read that reinstalling magiks will cause you to have to reinstall ROM. You can also install xposed w/ xposedinstaller_3.1.5-magisk.apk.

I have also tried to run flashfire but it crashed every time i open it sadly. Given I don't have a custom recovery I cannot install vanced that way, the magisk repo has vanced missing now and the plz script gives the v15 error LOL. Es no bueno. Anyone have vanced running and care to tell me how they managed it? I do have xposed so I suppose I could go that route w/ an alternative.
[MTCD Software Development] p_mike83:
Hello,

I didn't try to fix magisk, but managed to install xposed. Flash fire could not flash framework ( I tried 2 times with different settings, all I got was a black screen. Thought I broke the unit but it restarted normally) . using xposed app I could download + install the xposed framework from the internet without rebooting in recovery. Hal9k agreed that magisk installation has problems and would be fixed in next version. He said he could install xposed module though( I don't know if he did that using magisk or my way).

Maybe there is a way to reinstallmagisk without updating. My internet search didn't give any good results how to do that.

As Hal9k said magisk would be fixed in next version. You could install YT vanced for non root users until a magisk fix is available.
[MTCD Software Development] TT_Vert:
Yeah I have xposed installed. I know I could install but it requires gapps be installed also. WIll that conflict current google apps install? That was my concern as I don't know the exact purpose of gapps

[MTCD Software Development] mchouaibi:
I have youtube vanced installed with this rom, without the need of xposed or a custom recovery. You have two options.

1. Install the non root version. You can download the apk and install it. It will not overwrite the original youtube. You wil have both versions. You need microg apk to log in with account.

2. Remove the original youtube (with titanium backup) Download the root version. Rename it to Youtube.apk. Use a root explorer like Solid Explorer. Navigate to /system/app. Copy the apk to this folder, reboot device and voilla.

Both ways worked for me. I prefer the second way.

Having an issue with Google Maps on this ROM. Can anyone help.

So starting Google maps started making the screen go blank, and while it still seemed to respond to touch it required a poke of the reset button to get the display back.

I uninstalled and reinstalled Maps, and now it displays, and you can search for places but as soon as you press the "Directions" button, Maps crashes, every time.

Not sure what else to try, I'm currently several hours drive from home! It's an Xtrons TE706PL, GS MCU v2.94 with the wadzio sound mod.

Edit: It got weirder. It seems to only be one destination that causes the app to crash, no idea on the black screen issue but that seems to be gone now. I'm gonna suggest it's more an app problem since other destinations work fine.
[MTCD Software Development] TT_Vert:
Is anyone else with physical buttons having an issue w/ the volume and home buttons not working when coming out of sleep? When I go into factory settings to check and test map of buttongs the MCU is seeing the presses just fine.

I may try a different MCU to see if it makes a difference but this is an MCU that isn't listed around here anywhere. It's a MTCE_CZ_V2.84_1 Given it's a 2.84 I assume it's either a derivative or copy of other 2.84 MCUs. Fortunately I can back up my MCU and it seems the MTCD/E MCUS are interchangeable between units. WIth that said, has anyone else run into this?

Thanks

Anyone else unable to turn off the screensaver (non android screensaver, but mod screensaver) in some apps?

Hey guys quick question. In the bluetooth.apk dialer file you can minimize to use the screen which is awesome . I have one finding/request/issue that perhaps there is a work around for or an easy one can be baked into the next version. When the bar is minimized during a call it still renders that bottom bar where the bar was before it was hidden is unusable. I use Waze and during a call I cannot click on anything at the bottom of the screen there. (Search, routes, etc). Anyone else notice this? Is this something that can possibly be rectified? I also ran into another bug which kills the BT stack, the power/volume button as well as the home button. I use a software connected to my radar detector and I find if the device is not on before attempting to connect it breaks BT as well as those buttons mentioned above. If I have the device on before there is no issue. If it loses connection mid use there is no issue either. I did log it but the pertinent info may be here (Note that the spp connect failed lines repeat indefinitely) and fill the log until the system is rebooted. Also the power/volume and home buttons are unusable as is BT. MCU still sees the keys as functioning when I go into the key config in extra settings. Tried a different MCU but it has no effect. BTW even though it says it is connected it actually is not connected at this stage which is probably part of the problem but that's how it's always been since I had it working on an MTDB device w/ Malaysk's ROM.

That sounds suspiciously like the sound associated with version mismatch between ROM an MCU. I know this ROM removes the red text but maybe beep has been left. What MCU are you on ?
[MTCD Software Development] TT_Vert:
You may be onto something. I am on a different MCU than my original although everything seems to work. The beeps went away and came back again at a later time. I did disable the beep sound so I don't hear it but if this is due to some mismatch then I can go back as it didn't fix my problem. What determines a "mismatched MCU" and what problems does it cause if any? I did notice I lost audio at one point also and rebooting fixed it. I did back up my stock MCU before upgrading as my MCU is some odd MTCE that isn't listed anywhere. I'll get the info later but the new one is ->MTCE-KLD-2.94es (Sound Patched) KLYDE (KLD-suffix) dmcu(MTCE-KLD-2.94es by cs-x).7z
