How often are Firmware upgrades online for this unit V1 Pro ? Thanks
[Android Head-Units] TorstenH:
It's always a surprise when the sellers send a link to a new firmware to one of their customers. But in most cases the changes are not worth the effort to re-install the system.
[Android Head-Units] PrinceLc:
Okay thanks till now all is working okay
[Android Head-Units] Jafste:
Any of you have wireless carplay, is it good?

Can i have still use mobile data ?
[Android Head-Units] PrinceLc:
Yes with CarLetter app and mobile data is there normal
[Android Head-Units] PrinceLc:
Found this with Activity launcher OTA updates !?
[Android Head-Units] Jafste:
i dont have carletter, the apple carplay to me is "Phone Link"
[Android Head-Units] PrinceLc:
Look in factory settings 8878 others than carlink there you see -+ tap + till CarLetter appear
[Android Head-Units] TorstenH:
No, this is not working. Checked that several month ago - no OTA updates found.

Other questions do we have a dark mode ? V1 Pro mt8259 4gig

[Android Head-Units] PrinceLc:
Do you have installed the latest version v90 ? This app is new
[Android Head-Units] Jafste:
unfortunately my version, can not be update, because my version is for bmw and has a custom rom but if you have a an update for v90 with 1980x720, i can install and check it out.

The seller is trying to sell me a code to active wireless carplay (for autolink) is it worth it?
[Android Head-Units] PrinceLc:
Ah okay sorry I don't have for your car an update
[Android Head-Units] Jafste:
yeah, its the norm.

I can install the generic update, but if its not 1920x720 it wont show the full screen, i dont mind the generic since i can install a launcher and it will work out the same way :)!

If you ever see one I would appreciate it
[Android Head-Units] Morpheuspt:
No idea. Can you check the factory settings?
[Android Head-Units] rav4junsun:
I spent hours going through the settings 😅 I found a CarPlay toggle in the hidden menu 8877. When I enable it, the CarPlay works. However when I turn off my car, the setting is lost. So every time I need to enter these settings again, which is quite annoying. Also sometimes CarPlay stops working and I have to unplug the iPhone. Wonder what I can do to get it working again.

I deleted some other apps that had microphone access and which I don’t need. However one of these apps might have been l connected to phone link.
[Android Head-Units] joeling:
Hello, I installed the update 8259P_军灿UI02v1280x720-国外_v27_20211201.zip, everything works fine, except the resolution that is distorted, also an annoying bmw menu appears on the right side when swiping, any way to recover the resolution and remove the menu?
[Android Head-Units] TorstenH:
Please try and validate the setting without an flash drive / USB stick.
[Android Head-Units] TorstenH:
Please provide a screenshot / photo.
[Android Head-Units] rav4junsun:
Not sure if I understand. What do you mean by that?
[Android Head-Units] TorstenH:
If you're using an USB stick while changing the settings it may not work to change a settings. So remove all USB devices from the head unit.

Hi All

I have a Xonrich 6/128 for BMW CCC E60. I find that the idrive controller stops responding when i exit the car and lock it > 1 minute but less than 5 mins. Then i'm back in the car, start it, everything works fine except the idrive controller. However if I leave the car for 30 minutes or so the idrive controller works again.

Does anyone have any insight?

Much apprecaited.

Thanks.

Sam
[Android Head-Units] TorstenH:
Is the head unit performing a reboot if you leave the car for 30 minutes?
[Android Head-Units] insanesam:
No when i start the car its loads immediately (sleep mode = on). I have also set the "sleep mode" off, to which the head unit does a reboot (showing the factory logo). The idrive controller still does not respond. But in either mode, leaving the car off for about 30 minutes fixes it.

Nope. It's even not necessary to update the fw if you have no problems. ;-)

Carletter is in folder

system/tsoem/carletter

of the v90 firmware file. You can download the generic update, use latest version of 7zip to extract the files from mentioned folded. It may be possible to simply install the carletter apk on your head unit.
[Android Head-Units] Jafste:
I installed it, but it gives me an error trying to active.
[Android Head-Units] TorstenH:
If you share the Carletter apk file I can try to check which activation file is required.

Hi everyone

I was asking if there is a modified MainUi.apk

For benz just like bmw so we can update the main firmware to the latest update and still have the personalized settings for the benz interface
[Android Head-Units] TorstenH:
You could share your MainUI and the name of your firmware zip file. Then I can have a look if there is just a small difference.

I already created a variant for BMW but got no feedback if it's working. :-(

[Android Head-Units] mahmoud.hassib:
That would be perfect since as you know or as i think mainui.apk is just a layover mcu functions hence the ui part so if we can keep it on track with firmware we can have a lovely ui over the firmware , you can correct me if i got to much optimistic 😁
[Android Head-Units] mahmoud.hassib:
If it works i can help with all ui elements and graphics as we can renovate the whole icons,pointers, backgrounds of the whole poor unit
[Android Head-Units] scousemartin:
to automate apps on startup , for any headunit, just use an app call macrodroid, with that you can automate ANYTHING. I have it on my headunit and android phone, so when my phone connects in car it automatically switches on hotspot and the headunit automatically switches on wifi and connects to the hotspot. It also starts up my ssatnav and music app too.
[Android Head-Units] TorstenH:
My suggestion is to use AppSwitcher in combination with Automate 😊

AppSwitcher starts automatically the last used media app and allows to replace the mode button functionality

AppSwitcher v3 - smart SWC launcher (for Junsun, Xtrons, Ossuret, Hizpo and similar devices) incl. autostart

AppSwitcher v3 SWC (Steering Wheel Control) app launcher Stay focused on the street and don't touch the head units display to switch between apps. Support the development of this free app via ko-fi.com/appswitcher

[Android Head-Units] Jafste:
my unit does not let me install that variant :(.

I am searching for un update that works with 1920x720, so i can switch and use the generic instead of the firmware for bmw.

The carletter is still the same, it says activation failed, maybe i need to put some files somewhere, i dont know where.
[Android Head-Units] TorstenH:
In most cases it's just the lack of testing support which stops development of

Which message is appearing?

Du you have a MTK825X device?

Which apk you tried to install?
[Android Head-Units] Jafste:
My device is 825X, yes, when i try to install the apk it only says failed to install, nothing more.

i tried to install the CarLetter the one you sent, and nothing and even tried to install the new update that was posted before and same error.

I think the firmware in my unit does not let me install that.
[Android Head-Units] TorstenH:
But you can install other apks? E.g. from apkpure?
[Android Head-Units] Jafste:
yes, i installed aida64 and other apps, and i installed the carLetter for example, but some it fails.

Is it possible, to change the resolution of the firmware, to 1920x720, i am 95% sure that is the firmware that blocks certain apps?
[Android Head-Units] TorstenH:
You should try to install the apk and check with logcat reader why installation fails.

Without a error message no chance to investigate the issue.
[Android Head-Units] PrinceLc:
Can we have on the V1 Pro on the status bar the battery voltage?
[Android Head-Units] Jafste:
this is the error
[Android Head-Units] TorstenH:
But this is not an installation related error. I would suggest to install the app again to bring up the generic error message.

Then search the Android log for "install" and check the error message bottom to top.
[Android Head-Units] Jafste:
For the carletter that's the error for the activation.

At lunch time i will try and show you an error on the installing an app.

But is it possible to change the resolution on an update? i would prefer installing the v90 update on my unit, but mine is 1920 instead of the 1280
[Android Head-Units] TorstenH:
Still the same message "Invalid activation type" when testing Carletter_act.apk?

I shared adb commands to change resolution a while ago. Should be easy to find with Google.
[Android Head-Units] Jafste:
Yes, when i hit active that message appears on the log.

I will try, hope is not too difficult, that will probably fix all my problems :D
[Android Head-Units] Jafste:
I got the CarLetter to work, how should i active it?
[Android Head-Units] PrinceLc:
In my case CarLetter was activated by default, Autolink not. Try it like the method online to activate ZLink or so.

Hello everyone. I have an 825x 4/64gb device for Audi A4 B8 (1280 x 480) (CAN #152)

I have spent a lot of time trying to get it to work properly.

I would appreciate any help with the following:

1) Looking for the latest firmware for 825x with a 1280 x 480 (stretched screen).

2) Looking for the newest version of AutoLink for Android Auto.

3) What are the alternatives to AutoLink?

4) Is it possible to enable wireless Android Auto? Currently, only CarPlay is available (my phone, Google Pixel 6, supports Android Auto).

5) Problem: In AutoLink version 2.0, multitouch is not working. Can be fixed?

6) Problem: Sometimes when I start the car, only a black screen is displayed, and I need to press the "home" button.

7) Problem: AutoLink program minimizes on startup, and I have to reopen it."

8) I tried to install the firmware from Junsun with a resolution of 1280x720, and the car's native menu doesn't work on it. Please provide a link to the application that needs to be reinstalled for native car menu

Thank You

[Android Head-Units] Jafste:
major update, i have to install it everytime the car starts ( tested 2 times).

But did not ask for activation, but it starts the hotspot and Bluetooth.

But to enter i have to click phoneLink, and it changes automatically to CarLetter, and after that it works perfectly.

And i can use my mobile Data, at the same time, and i was afraid i could not.

I tested this on the generic version v90, will try on my BMW version, since updating the Resolution f*cks the back camera.
[Android Head-Units] TorstenH:
That means the activation issue is fixed. That's a good message, isn't it?

Are you using the standard Junsun launcher? Are you sure the app is not installed after a reboot?

Have you checked the Android app settings to see if CarLetter is really not available?

My current assumption is, that the launcher is just hiding the app.

I don't think that it changes from PhoneLink to CarLetter. I just think the launcher is using a weird shortcut with a wrong description.

Please check if CarLetter can be selected in factory settings (8878) instead of PhoneLink / Suding.

Nice
[Android Head-Units] Jafste:
That's great, i am doing in 2 weeks a 1200km, and its good that i can charge properly the phone.

The app is still there, but it asks me for activation, and i update it again for the version that you gave me, and it did not ask again.

To be honest, i dont know why, everything is set up right but it goes for a infinity loop looking for the phone, but if i click on PhoneLink (that appears even if CarLetter is there) it jumps to the CarLetter app and it runs properly, and even if i close the CarLetter i just need to open it again from CarLetter, no need to go again for PhoneLink.
[Android Head-Units] TorstenH:
You're confusing me!

I patched the app to suppress the activation. So I think that's okay, now.

You need to disable PhoneLink or disable autostart as soon as phone is connected. It may get started automatically.

And please keep in mind that the Chinese have a different understanding of "set up right". Because based on your settings in 8878 one app gets uninstalled and another app gets installed. This would avoid that both apps are running in parallel.

We're just using a workaround and are installing CarLetter as and usual additional app.
[Android Head-Units] Jafste:
Tomorrow i will make a video explaining, but for me is working fine.
[Android Head-Units] rov3rrepo:
Would this also work for the 8259 CIC BMW E90 version? If so I might give it a shot. MainUI is the entire firmware? Or like a launcher? I'm experiencing errors with adding the AutoLink app to the main launcher screen and it being forgotten almost every time the car is shut off.
[Android Head-Units] rov3rrepo:
You asked before if anyone has tried AutoLink on a BMW. Yes, I have it and it works great wirelessly for CarPlay. Bought a code but had to change my country to france for it to let me purchase. Then it was digitally delivered to me.
[Android Head-Units] TorstenH:
You may be interested in testing CarLetter, too. Would be great to have additional test results.

https://xdaforums.com/t/junsun-v1-pro-mtk8259-mtk8257-firmware.4283365/post-88785627
[Android Head-Units] TorstenH:
No glue. You need to test it...

MainUI is one of the core system apps which is like a UI for the MCU. The launcher is a separate app.

Does you launcher forget only AutoLink or other apps you add to the main screen, too?

If only AutoLink gets removed we could create a launcher app which creates a separate icon.

The link to the V90 firmware is broken. Does anyone have a working link?
[Android Head-Units] TorstenH:
First post, first link.
[Android Head-Units] Jafste:
The video I promised:

A question, is it possible only to adjust this camera, it cuts the top?

Another question, is there any tutorial how to root the unit? I think its possible to have carLetter on BMW firmware, if the folder system has the folder "CarLetter" on the V90
[Android Head-Units] TorstenH:
According to the installation screen the installed app gets updated.

- do you have two icons on launcher or only one after installation?

- does the activation screen appears again after reboot? This would mean the app update does not survive reboot.
[Android Head-Units] Jafste:
Will check later, every time that i change the resolution the backup camera stays that way, even after reboot.

Only one.

Yes, it appears again after reboot.
[Android Head-Units] PrinceLc:
In the video CarLetter will connect, to connect your phone activate hotspot on the unit and connect your phone to the hotspot also this is with Android Auto the case
[Android Head-Units] Jafste:
I know that, it starts and connects automatically its just a "bug", nothing much.

The only "hard" thing is that the apk has to be installed everytime the unit reboots.
[Android Head-Units] PrinceLc:
Ah okay the best way to find a modified firmware for your resolution
[Android Head-Units] Jafste:
i will root the unit, and try some things.
[Android Head-Units] TorstenH:
Could you please check the version code of the pre-installed CarLetter app after a reboot? It should be visible in Android app settings.

Additionally you can try to find "uninstall" and "InorUinstallAPK" in Android log to check if MainUI removes the update.

TorstenH​

I Installed your version of Carletter in my Mtk8257 (Roadanvi F10) that has Alink v 2.0.19. Installed OK, no errors, no request for activation, but not working at all. Only Alink works in wired mode!
[Android Head-Units] TorstenH:
Thank you for testing. Your could check the Android log for errors because I don't have a chance to find the root cause based on "not working at all".
[Android Head-Units] PrinceLc:
Did you have activated hotspot on the head unit and connect your phone with the hotspot? My CarLetter is activated by default and I have only connection with hotspot of the unit
[Android Head-Units] Alfarroba:
@TorstenH

What I mean by not working at all is that Carletter do not open AA either wired or wireless, but Alink still works wired.

By the way, can you tell me please the difference between 4 and 6 pins USB cables?
[Android Head-Units] Alfarroba:
Yes I activated the hotspot on the HU. The phone was connected to it and also BT.

Also connected the USB cable.
[Android Head-Units] PrinceLc:
Maybe change hotspot name and password and try it than
[Android Head-Units] Jafste:
If the firmware its not the v90, i too can't use carLetter, so if you dont use v90, it does not work.
[Android Head-Units] Alfarroba:
Maybe that is the reason :(
[Android Head-Units] Alfarroba:
I can do that but as @Jafste said: I have not V90 firmware as my HU despite being Mtk 8257 is not a Junsun v1 pro. Maybe a clone!
[Android Head-Units] PrinceLc:
Okay that's maybe the reason but our soc is 8257 too called only 8259
[Android Head-Units] Alfarroba:
Like mine!
[Android Head-Units] PrinceLc:
I think so called 829xPro but soc is 8257 when you look Aida64 or Hardware test apps
[Android Head-Units] Alfarroba:
some info on mine
[Android Head-Units] TorstenH:
But it would be interesting to know what needs to be done to get it running on a non-v90.

Unfortunately generic answers like "it's not working" don't help. That's the reason I asked for checking the Android log.
[Android Head-Units] TorstenH:
Please check the Android log. Without a error message there is no chance to get it running on a non-v90.
[Android Head-Units] Jafste:
i can try to help, i will install my version, and will read the log codes.

I wanted to root and try somethings, but the unit does not recognize the usb to type C.

Today i bought the autolink code, so i can check if that makes any difference, i doubt it.
[Android Head-Units] TorstenH:
At least you have the issue that the head unit resets the app. A few posts ago I suggested some key words you can try to find in the log regarding this issue.

I makes no sense to mix up AutoLink and CarLetter. They should work independently.
[Android Head-Units] Jafste:
I will try, if i have time today i will check it out.

i think so too, but after the PhoneLink thing i will look into it, i wanted to try it out too to.
[Android Head-Units] Alfarroba:
Sorry for the question, how to get the log?
[Android Head-Units] Alfarroba:
If we unninstall Alink/Phone link will we loose the activation?
[Android Head-Units] TorstenH:
You could install logcat reader from Google Playstore.
[Android Head-Units] Alfarroba:
Thanks, I will try to get it
[Android Head-Units] Jafste:
This is the error that i have
[Android Head-Units] TorstenH:
This is not an error related to an app deinstallation. We can ignore this error for your case.

Please update the app again. Force stop MainUI via the Android app settings and check if CarLetter gets reset.
[Android Head-Units] hoalcraftbilly:
Can you use a apk creator app and make an install file for autolink we can use to update ours?
[Android Head-Units] TorstenH:
Next try to get CarLetter running...

The Zip contains a prop file with needs to be placed on the root folder of internal storage. The file needs to be on the same level as e.g. the "Download" folder.

I re-enabled the licence screen because I think the prop file contains the activation type.
[Android Head-Units] TorstenH:
I could create such an app but this requires you to test it - maybe not only once!

Let me know if you want to have such an app and you're willing to test it.

But have you already tried to install the latest version (attached) by simply clicking on the apk file?
[Android Head-Units] Alfarroba:
Here is my android log. hope it can give some light on the issue. The file is not uploading. it stpos at 60% and then? it has 3.12 Mb. Is it to much Trying to zip it
[Android Head-Units] TorstenH:
Was the log created directly after you installed the modded CarLetter version and performed a reboot?
[Android Head-Units] Alfarroba:
Did not reboot.

I installed your last upload but gives activation error. I did copy the carletter.prop to the root folder
[Android Head-Units] TorstenH:
Please update the app, reboot and grab the log. Because we want to know if the app gets reset after/during reboot.

Please install the last mod, copy the prop file and connect your head unit to Internet while starting CarLetter the first time.
[Android Head-Units] Alfarroba:
I did everything you suggeted. The older log was done after the reboot. The newer log was done after that and after lauching carletter.

I copied the prop file to the root and instaled the new app over the previous one, it was like an update! but the result is the same, photo in the zip.
[Android Head-Units] TorstenH:
Bypass the activation due to activation error "Invalid UUID".

Not getting the error "Invalid activation type" is an indication the prop file gets considered.
[Android Head-Units] TorstenH:
Installation as update by clicking on the apk file in file explorer worked without issues. Update survived reboot. (-:

There seems no need to update the full firmware just to get latest AutoLink.
[Android Head-Units] Alfarroba:
I installed your Alink 2.0.25 over my 2.0.19, updated and works with AA wired. But I cannot pass the Carletter activation error as shown in the photo
[Android Head-Units] hoalcraftbilly:
This is exactly what I was looking for. Android auto wirless still don't work. I manually create a hotspot on the headunit and then connect to it with my phone but it just sits on the connecting screen. I think I may just buy one of those wireless adapters to make this work wirlesssly.
[Android Head-Units] TorstenH:
Have you changed the name of the hotspot on the head unit? You should do that and try again.
[Android Head-Units] TorstenH:
AutoLink and CarLetter are separate apps. An update of AutoLink will not change a missing activation of CarLetter. No need to mix both apps in one post.
