Hi,

I have a lot of problem with the GPS Wich sometimes take from 5 to 20 minutes to fix the first time. And after, I often loose the signal. It depends where I am, close to my house, it is working well, arround 2-3 minutes to fix.

I have a PX5 with the hal9k v4 without OTA update. I saw a lot of change about the GPS in the changelog, but I don't know if the OTA will resolve my problem as hal9k say that it can be an hardware problem. But I had no problem on the v3...

I hesitate to pay for the OTA update because I don't know if in the future we will to pay again for the OTA for example for the hal9k v5. We already need to pay for the mod installer pro v2 even if I have already purchased the previous version :(

Do you have any idea if the OTA will resolve my problem, or do you have other ideas where the problem can be?

I spend a lot of time to setup this ROM which works perfectly, except for the GPS wich is a mandatory function :(

Thanks.

Did you perhaps flash a Wadzio sound mod MCU on Android 8? I did so at the time and when I updated to Android 9 (could not use Wadzio's Amp app on Android 9), output was rather quiet. I fixed it by flashing a non Wadzio MCU. The CS-X sound mod MCU (the one that works with the original amp app) does not have this silencing effect so that one can stay.

Viper is active after boot if you keep it from being terminated at standby -> Mod settings / app manager.
[MTCD Software Development] JonnyG1980:
I do have a modded MCU flashed from Android 8, yes! Just to make sure I get the right one, please could you post a link to the CS-X sound mod? Will check out the mod settings too. Amazing work, thank you!
[MTCD Software Development] Hal9k_:
OTA-package v4.1.0 is available for download.

List of changes in the first post.

In order to reduce the size of the package to reduce download times, this update is made differential.

That is, it only contains information about changes.

If the update is not installed, you should install the base version 4.0.0 and reinstall the updates.

If this happens, write to me on which file the installation was interrupted.
[MTCD Software Development] naira1:
No it won't. GPS in Android 9 is just bad.

I've moved away from this ROM and other Android 9 rooms ROMs bcos of this GPS issue. I travel a lot and don't want to always use my phone to navigate.

I must say the issue with the GPS is no fault of Hal9k. Just Android 9 is terrible with it.
[MTCD Software Development] Hal9k_:
You haven't tried version 4.1.0. :D
[MTCD Software Development] noise672:
I agree...

I ran away from A9 as fast as I could. With the help of ModInstaller Pro.

But... Hal9k_ says his new release 4.1.0 ...:D

Hello all!

How can i remap psychical button (eject DVD) to start other app?

I want to click eject dvd button to start app like Chrome. I don't need DVD :X
[MTCD Software Development] verbumomo:
Don't know why many complain with gps. I'm on hal9k 4.0 and it works fine, it fixes after 5 seconds from boot and I never loose signal. I use it daily on a Witson px5 4/64 - maybe they use a heavy app with a px30 2/16...

You can get the keycode in tasker or with mtcdtools. These apps can open any app you want when pressing a hardware key

If you don't use the DVD drive, it should work without problems

Stuck in a boot loop after latest ota update. I tried wiping cache, to no avail. I would like to avoid reseting the unit. What should I do?

Thank you for your work!
[MTCD Software Development] marchnz:
What options have been considered?
[MTCD Software Development] Moldeb:
This is the CS-X thread: https://xdaforums.com/android-auto/mtcd-software-development/mod-cs-x-mod-mtcd-e-mcu-firmware-t3816042 - but you can also use the stock MCU for your unit. Neither stock nor CS-X should have the silencing issue. If you use Viper4x you don't really need CS-X, I have it (no need to uninstall) but left it on neutral and do everything in Viper4x now....
[MTCD Software Development] okij:
Oh no, I just read the changelog and the known issues in the first post and saw that the black screen (Malevich) bug still hasn't been fixed. :crying:

Why did you update the base firmware only to version 201912 and not to HCT4_PX5_9.0_ota(2020/05/09) with the fixed black screen bug?

I was hoping and waiting for this fix and now I'm really disappointed. :(

Will you make another update which is then based on HCT4_PX5_9.0_ota(2020/05/09)?
[MTCD Software Development] RomainD2:
So we have no choice but to wait for an Android 10 hal9k ROM? Which ROM did you choose?

Dis you tried it? Is it better?

I have a PX5 4go/64go... I use Google map and camsam plus.

I have just seen the new OTA update, I don't understand why there are so many gps things improvement in the change log, and hal9k say that it will not resolve my problems... :(
[MTCD Software Development] Hal9k_:
Did you change any files in the system partitions ?

Enter into recovery and install the base firmware without wipe and updates.

This was necessary for the differential update.

Yes, now we will switch to the latest firmware.

Because I'm not a clairvoyant.
[MTCD Software Development] megatm:
I've unistalled Google Chrome, as it's a system hug for my 2gb ram hu. I'm using Firefox nightly. But when I would install 4.1 ota, it fails to install.

Is there something to fix it or I need to install Google Chrome as system app again?
[MTCD Software Development] Hal9k_:
You didn't uninstalled it, you deleted it. These are different things.

You just had to disable it in the Settings.

You need to install the base firmware without wipe and updates.

Dasaita PX-5

Hallo,

yesterday I've received my Dasaita PX-5 4GB Ram64GB Rom. I wanted install the hal9k Rom, but it doesn?t work with this file I?ve downloaded here. Can anyone help me? The Radio is on Android 10 yet, is there a possibility to install this ROM?

greetings cnayo
[MTCD Software Development] naira1:
No I haven't. Now you are tempting me my friend.

---------- Post added at 03:25 AM ---------- Previous post was at 03:16 AM ----------

it's the Dasaita PX5 Android 10. Think it's called HA3. Have it for 2 weeks plus and do like it a lot. But missing the customisation that Hal9k ROM brings. So I might be trying his latest update soon again.
[MTCD Software Development] megatm:
OK. I'll do that. But disable it's not unistall. Those are totally different. When you unistall something, it is deleted. But ok. Thank you anyway.
[MTCD Software Development] Hal9k_:
You can use ModInstaller Pro.

Aha. ;)

With the latest fix, the GPS on my PX6 works perfectly just a minute after coming out of sleep mode in the morning..

I would be interested to know what is happening on other devices.

In Android, this is almost the same for system applications.

In this case, none of the application components will start. It just stays in the app list.
[MTCD Software Development] okij:
Thanks for your reply! That soothes my worries. :)

Will you make an update based on the latest HCT4_PX5_9.0_ota(2020/05/09) firmware quite soon?

You don't need to work on any new features (there are already plenty of them :cool:), just to switch the base firmware to fix the black screen bug.
[MTCD Software Development] RomainD2:
I understand that, but maybe I can give you some logs in order to understand what happen with these gps issues, as I am not the only one, I doubt that it is an hardware problem... And again, it was working fine in your previous ROM...
[MTCD Software Development] Clandaries:
I have installed the latest OTA on my MAX6.

GPS was right there after starting the head unit.
[MTCD Software Development] Hal9k_:
I'll do it as soon as I can.

Let's not forget that it's summer ! :victory: :cool:

Read reviews about the latest update and just make a decision for yourself.
[MTCD Software Development] aryanitinkumar:
Did you try the gps config fix? It certainly did help me mod the gps config on my unit.

You can read more on

https://xdaforums.com/showthread.php?t=1429266

or then try on the gpspower.com ..

https://www.gpspower.net/igo-tutorials/327919-how-get-super-fast-gps-locked.html

Or then you can well choose and try out android 10 ...gps is great but of course you will have to customize the official ROM to your tastes.

Hope this helps.
[MTCD Software Development] JonnyG1980:
Thanks again for your assistance. I've hadn't changed anything on my headunit for over a year but since updating to Android 9, and subscribing to OTAs and changing my launcher, but now I'm having a hard time remembering everything I've done previously.

After I do the latest OTA today, I'll flash the CS-X MCU (I'm not sure if I have a backup of stock), where are the controls for it so I can check the sliders? Are they just in the standard amplifier app?
[MTCD Software Development] jrobbom5:
For some reason, "Replace Key Codes" has stopped working for me. I was using this to remap 2 of the buttons on my steering wheel (mode and R/T), it used to work fine. I hadn't used it in a while though, and when I tried yesterday the mode button had reverted to being a mode button. I selected "Show Key Codes", and Hal9k can correctly identify a key when pressed, it just doesn't seem to be able to replace it anymore.

Anyone seen this before? And advice or suggestions most welcome.
[MTCD Software Development] fetti6:
I'm having this issue coming from 4.0.2 PX5.
[MTCD Software Development] Moldeb:
Yes, CS-X works with the standards Amp (equalizer) app that comes with the firmware. Wadzio needs/brings its own. Assumed you used Wadzio's solution on Android 8 (as I did) then the move to Android 9 will have overwritten Wadzio's amp app replacement with the standard one, hence the sound chip is not configured correctly in MCU and too quiet. CS-X / stock use the same original amp app that you have now. See the CS-X thread I linked to earlier for details.

BTW it makes sense for everybody to keep track of changes they're doing. Often people perceive to have issues with Hal9k but actually the problem is due to another change made earlier (and overwritten by updating firmware or else) ;)
[MTCD Software Development] Manfred.62:
PX5 from Dasaita (MTCE HA): just done the OTA update without problems. GPS fix is fast
[MTCD Software Development] Silver_:
My friend [MENTION=5092263]Hal9k_[/MENTION], if you do not mind, I would like, for the next update, to make it possible to change the display of the car for parking in full screen and not the ridiculous image that appears on the left of the screen. Especially for those who do not have a rear or front view camera. I mean something like this:

[IMG="Parktronic"]https://images-na.ssl-images-amazon.com/images/I/518dEUnPtZL._AC_.jpg[/IMG].

A lot of the modifications that you made in the lines of the camera are appreciated but for those of us who do not have a camera it is not worth it.
[MTCD Software Development] dib2000:
Hi,

how do i reset the hal9k launcher
[MTCD Software Development] Moldeb:
Same here for a MTCE KSP PX5/4/32. Came up normally and is working fine. GPS fix is fast. I use Agama launcher, didn't need any changes.

Has anyone figured out already whether the newly added additional dim behavior (night) is compatible with the Backlight Autolevel app https://play.google.com/store/apps/details?id=com.microntek.romavaleev.backlightautolevel? Have been using that as the lat/lon approach makes more sense to me than lights on/off...

Worked well with the previous versions.
[MTCD Software Development] JonnyG1980:
Just wanted to say thanks again for all the assistance with getting my volume issue fixed. I had fears that it was going to go unanswered for many days / weeks. It makes a big difference knowing that folks are out there waiting to be helpful.

I've updated to latest OTA, re-flashed the CS-X 2.94 GS MCU, re-set the levels in factory settings and had to bring down Viper's gain controls massively as it's now louder than ever. Only thing to look at now is if there's any point in installing Agama Launcher via Hal9k's new method which I spotted in the update notes.
[MTCD Software Development] Moldeb:
Glad it worked :)

As regards Agama - I don't know really as I installed it ages ago (as ordinary launcher apk then defined it as standard launcher) and it simply survived the updates...
[MTCD Software Development] RomainD2:
Should I conclude that some device had gps issue before the last update, and now it is fixed?
[MTCD Software Development] JonnyG1980:
You knew I was going to ask this... How do you define it as a standard launcher? Any benefit to that?
[MTCD Software Development] ric69:
GPS is starting very quickly yes on 4.1 and px30 but position is still a bit laggy (5 / 10 km/h difference) i have full satellites in use. I'm doing some test with frequency now 1hz instead of 10hz and after 5hz. I will post results later. I don't know how it works

Thanks for great work again hal9k :cowboy:
[MTCD Software Development] Moldeb:
It should offer you that on first launch, else it's in the standard Android settings (where you also select the standard browser etc). Advantage is that the launcher acts as home screen not only after starting the launcher app manually.
[MTCD Software Development] JonnyG1980:
Ah, in that case yes, did that. Set as default launcher, press home button, always goes back to Agama. Cheers!
[MTCD Software Development] Wesenwesen:
Hello, Hal9k,

yesterday evening I received the update to version 4.1.0. It went smoothly through, no problems.

Today I noticed that my data dongle (Huawei 1750) is not recognized anymore. The data symbol says there is no simcard inserted.

But with version 4.02 it always worked fine.

Can you help me here?

Greeting

Arno
[MTCD Software Development] okij:
Actually I didn't have problems before with GPS fix on my PX5 4/64GB Witson (MX) head unit on 4.0.0, 4.0.1 and 4.0.2, so I cannot comment on this.

But it appears that the head unit became more fluid and responsive on 4.1.0 even under heavy load and when the CPU is hot, so the changed rules for distributing processes by processor cores indeed have a positive affect on the system as a whole, as you wrote in the changelog. :good:

So thanks a lot for the 4.1.0 update!

Now only the black screen bug remains to be fixed on Mod v4. :fingers-crossed:

Please don't let it take too long, but enjoy summer too! :cool:
[MTCD Software Development] MarcoZ76:
[SOLVED]

Hi!

Today i tried to update the system with OTA update 4.10 from 4.02. Unfortunately the process stopped at 99% and so i tried to reboot my Dasaita PX6, restart again the process started again from 99% but it wont continue, just stopped at 99%.

There is a way to deleted the partial code downloaded (probably corrupted) and so i can start again from the beginning ?

Thanks in advance

SOLUTION: I deleted the OTA zip with "Root explore", rebooted the head unit and then it worked!! Downloaded without problem and smoothly installeded. Well done Hal9K!!
[MTCD Software Development] Hal9k_:
This device does not have and does not use GPS configuration files.

Just checked on my PX5 test device.

This function works.

What code do you change to what ?

Did you install the fixed version 4.0.0 that I published back in February ?

We'll see.

I don't have such functionality in the HU that is installed in the car.

I don't have my launcher.

To start, restart the device completely and reconnect the modem.

Yes, something like this was going to happen. :D

The server could temporarily block you if it received a lot of requests from you.

Restart the HU after some time and try to continue downloading.

Write here if it helps.
[MTCD Software Development] Wesenwesen:
[MENTION=233696]hal[/MENTION]

I've done that, it's no use.

Data mode still says there's no sim card.

The modem dongle is ok, I tested it.

And as I said, under version 4.02 it worked fine.

Can I possibly go back to version 4.02
[MTCD Software Development] Ammby:

So why don't you just dirty-flash 4.0 and let it update from there as recommended? That will reprovision the apk you deleted....

Hello! I've just installed 4.1 succesfully, but there is an issue. The screen is completely black right after android is started. System is responsive if i try to blindly click on it (I was able to start a music player after some tries). Does it have to do something with the new dimming functionality?

Any ideas what to do now?
[MTCD Software Development] pablosso:
Turn off the lights in the car and radio should increase its brightness. Click brightness and you should have 2 sliders, the one at the bottom is responsible for the screen dim you experienced.

At least it's what I did in my case.
[MTCD Software Development] SoberXDA:
Would you be so kind and post screenshots with exact location of the brightness button and sliders?

Maybe I would be able to blindly hit them...

Updated px6 to 4.1 OTA, it took a long time as the download speed was around 60K although I am using 4g hotspot

The update is really nice specially the auto start app and keep in background , i really needed it for my external tmps app

I felt also cpu is more responsive and HU is faster overall

Good job Hal9k ☺
[MTCD Software Development] okij:
For reverting you can install 4.0.0 again (important: without data wipe) and then only make the 4.0.1 and 4.0.2 OTAs.
[MTCD Software Development] _snIP3r_:

[MTCD Software Development] Nightjjr:
If this helps, I would really advise you to use this kind of USB 4G with WiFi. It is way much faster than using 3G

https://www.amazon.es/gp/product/B014WMEJ2Q/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

And you don't have to worry about drivers, since it works using WiFi

[MTCD Software Development] JonnyG1980:
Appreciate I may have to ask this question on the Poweramp forums, but not getting anything out of them on an existing bug report so...

When I first start my car, Poweramp isn't able to play any music for around 30 seconds, due to not being able to find the relevant files (I have all my media on a USB connected SSD) I presume there is a scan taking place somewhere but I can't seem to disable it. Album art is also unavailable for a little while.

I have Poweramp set to use only manual scanning, the auto scan on startup is disabled, so I guess it's going on in Android somewhere. Anyone have any ideas? Also would second a call for any help locating the controls for 3rd party apps' volume.

Actually is a real USB modem that can be used as router WiFi. It is quite useful in this cases when playing around with modificated ROMS. It is detected automatically as a 3G modem in this ROM.

Don't want to get into a discussion, just wanted to add some information about these kind of devices.
