If you already flashed

8259P_军灿UI02v1280x720-国外11_v3_20220422.zip

you have a device compatible with latest firmware you can find on the 1st post.

But as always: You're flashing at your own risk.

sorry, the sound settings of the 8877 don't change..why?

high Low.

I have an external system with amplifier and sub and junsun makes me desperate. it sounds terrible.

I replaced the amp and subwoofer with Audison and it's useless.

can viper4fx help?

Or do I have to get another car stereo

scusa, le impostazioni audio dell'8877 non variano..perché?

alto, basso.

Ho un impianto esterno con amplificatore e sub e junsun mi fa disperare. suona terribile.

Ho sostituito l'amplificatore e il subwoofer con Audison ed è inutile.

viper4fx può aiutare?

O devo prendere un'altra autoradio

[Android Head-Units] Justenoughtobedangerous:
Here is the image of the unit so have showing the launcher. Let me know if you need anything else.
[Android Head-Units] Justenoughtobedangerous:
I updated hoping to get the iDrive functionality Android wide but I still only have iDrive in the launcher and of course when I switch back to the car. I've asked the seller to check with their engineer to see if they have any more recent files as it appears as though the MCU file was the same version I had.
[Android Head-Units] IAmNotMe01:
i update it but i cannot connect my OBD2 anymore :( , other wise everting works great.. thanks for sharing
[Android Head-Units] Justenoughtobedangerous:
I was using Torque Pro but after the update, I reinstalled Torque Pro and there was a message saying this version was designed for an older version of Android. I haven't had a chance to check out any other OBDII Apps but it may be due to the App and not the now updated system. Not sure though. Glad to hear everything else is working though. Were you able to get the iDrive to work within other Android apps?
[Android Head-Units] IAmNotMe01:
nope , menu just working as back button
[Android Head-Units] Justenoughtobedangerous:
Bummer, there was a video posted

that goes into an Android wide iDrive functionality from an update for the PX6 units of which I'm told the 825x_Pro are MTK8259 units running a Rockchip PX6. The problem is the links are no longer active to the updates. So if someone can get their unit's reseller to get them an updated file and I believe it would be the MCU file. If you look at the instructions for the MCU file update it says the file is ts70.bin but the file my reseller sent me is a ts59-b.bin so I've asked them to double check if there is a more updated file. I'll upload if and when I find one.
[Android Head-Units] IAmNotMe01:
for me ob2 is important but i cant connect it to my headunit because i need to change bluetooth password of the headunit to 1234 but its not possible.

so you say we can use PX6 roms?

,
[Android Head-Units] Justenoughtobedangerous:
I'm working on iDrive functionality at the moment and my OBDII adapter is not connecting as well. From what I've read yes MTK8259 is running the PX6 Rock chip.
[Android Head-Units] Justenoughtobedangerous:
I received a Can file update from my reseller and posted it to this link. Didn't get Android wide iDrive support but might resolve other issues with the MTK 8259 units on BMWs E90, E60, etc, with CCC. Same link as before. Requested a working MCU update file hoping this will be the fix.
[Android Head-Units] IAmNotMe01:
than is will stick with Junsun rom for now , because of obd :(
[Android Head-Units] Justenoughtobedangerous:
I'll let you know if and when I get mine running.

Hi!

Which firmware can I put on this?thank you for your help!
[Android Head-Units] rav4junsun:
Hi! I have a CarPlay issue why I would like to reinstall the firmware on my V1 pro 8GB, 128GB which I use in a 2010 Toyota RAV4. Will this firmware work on my head unit?
[Android Head-Units] Morpheuspt:
Yes.
[Android Head-Units] rav4junsun:
Brilliant, Thank you so much! 🙏🏽 Will this also work if the latest firmware version is already installed? I got my head unit in January and assume this is the same version.

I tried to fix a microphone issue and somehow ended up losing the CarPlay app “phone link” that was pre installed. The seller gave me the phone link apk, but installing that didn’t bring CarPlay back. In another forum I found the hint that I gotta reinstall the entire firmware to solve the issue. Would you agree that this will do it?

Should I make a backup before reinstalling the firmware? I have no data on the head unit. So I thought this might not be necessary. What do you think?
[Android Head-Units] Morpheuspt:
There's no need to do a backup if you have nothing on it.

It should install the same version. I also bought my unit in january, but mine came with an outdated version.

Its not related to the time of purchase, probably more related to date of production.
[Android Head-Units] rav4junsun:
Did the update and everything worked smoothly. However the phone link app isn’t back. 🙁 I already asked junsun support and they sent me two different apk which don’t work. Do you have an idea on how I could CarPlay / phone link working again?
[Android Head-Units] francois95:
Before trying to flash v61, I want to understand a few things :

- last time I tried to flash v61, the install didn't finished. Do you think that having flashed firmware 11_v3 has fixed something ahead of that update?

- what are the difference between 11_vX firmwares and other ones? I read that it was a difference of android version but it look likes android version are often faked on these chinese devices so I'm not sure of that..

- do I need to flash an other intermediate firmware before flashing v61?
[Android Head-Units] TorstenH:
No I don't think so. You should try another USB drive and maybe use another device to put the files on the USB drive. I don't suggest to use an Android device to put the files on the drive.

Maybe it means which faked Android version is shown. Unfortunately the Chinese friends never add a change log. Often the updates makes no real difference.

No. It's always a full update so it makes no sense to flash an intermediate firmware.
[Android Head-Units] francois95:
actually it looks like my 4Gb/USB2.0 usb drive caused some issues. I flashed v61 with a 16Gb USB3.0 and all was working.
[Android Head-Units] lousido:
I have a Junsun V1 4/64GB installed in a Mercedes W245 and it worked quite well, it had some malfunction: the telephone microphone had very little volume, the screen sometimes stayed black and the reset did not respond, it was necessary to remove the fuse to retrieve it.

I just updated it to version 20230303_v61 following the instructions on the forum, all very well. I had to reconfigure the connections and install the applications that did not come from the factory.

By the way, this version brings less, better that it allows us modified apps.

Many thanks for everything.

Device seems to be faster (but still poor quality of built-in mike when phone call and 4G modem still slow)

). And it doesn't keep FM stations when recorded.

To do upgrade, I used a usb key 32GB not bootable formatted FAT32 with Rufus 4.0. Update started immediatly after head unit mount the usb key and detected files.
[Android Head-Units] TorstenH:
Many threads regarding bad mic quality are active here. Best known option is to use an external mic an desolder the internal one.

This is what i'm going to do. I'm looking first if there is external input. If not, I will have to open the box...

Hello!,

I have updated to the last one, v61, and what you can see in the photo appears in the system info. Is it still with the same firmware that it had?: I do not understand anything because before flashing it came out the same and I have seen that it really It install files again, has rebooted, etc.
[Android Head-Units] TorstenH:
That's possible because new firmware means not new OS. Maybe they just updated one of the system apps or another system file.

In many cases it makes no sense to install each update - especially if you have a well running system.
[Android Head-Units] Nawual:
Well, you are quite right. The radio arrived a few days ago and I wanted to update it before configuring it and putting it in the car. Thank you

Hello again. I have already flashed the new version. Everything is going well or at least what I'm testing. I have to say that I have the radio out of the car because it is being repaired.

One question, I can't find any restart option. I thought it was in the lowering bar but I don't have it.

Is there not that option?
[Android Head-Units] 81joseca:
I check the new version (v81), and the first contact is bad. The GPS doesnt works, and it keeps the problem that I can't log to my google account.
[Android Head-Units] 81joseca:
restart in my unit is a external bottom in the screen frame, is a hole market by RST. In SW is the android factory reset
[Android Head-Units] Nawual:
Yes, i have it too that bottom with the hole, but i was searching that option in the software.
[Android Head-Units] TorstenH:
Exactly. The reset hole does not perform a reboot. It cuts off power temporarily.

Here you can find a Reboot.apk which creates an app icon to reboot the head unit:

Junsun V1 - start equalizer/AUX/BT music/CarInfo... from launcher

Additionally to the attached launcher apps you can find here an additional set which e.g. allows to start radio: https://xdaforums.com/t/junsun-v1-start-equalizer-aux-bt-music-carinfo-from-launcher.4237797/post-85047137 The app equalizer.apk...

Now, I downloaded again the firmware from mediafire and now works, the GPS and google logging. Perhaps I have a corrupt image.

I should to do more test.
[Android Head-Units] TorstenH:
I don't think so because it's a zip file and the bin file is an archive, too.

Nevertheless great to hear it works, now.
[Android Head-Units] Marko055:
Installed and tested. I can say it is more snapier, touch is more responsive. The new version introduces a new theme with stations switch buttons, which makes our life easier. Improved radio audio quality. The rest is the same.

Question: Is it possible to change picel density or resolution, as I got updated from seller rom, it somehow got bigger resolution and everything got small?
[Android Head-Units] goc123:
everything went fine with v81 UPDATE, screen sensitivity is better and faster....
[Android Head-Units] Digit.ality76:
I see a huge difference with v81!

The autolink app is v2.0.25 and it eventually fixes the sound issue with the radio!

For anyone who is into hacking and adding functionality into the software (via modding MainUI.apk) the latest version v81 they have done something so that the apk can no longer decompile properly and you wont be able to mod anymore. v61 still works fine in this instance.
[Android Head-Units] TorstenH:
Interesting hint because I never seen a modded MainUI here on xda.

My attempts to decompile the apk (< 81) not resulted in code which can be compiled again.

[Android Head-Units] jazzor:
You can decompile it using apktool 2.5.0+ and recompile it again quite effectively. You can do some interesting stuff with this such as sending messages to the CAN to update your instrument cluster display to show useuful stuff etc, Or start your own services etc.

The way I do it is to compile my own service in android studio with added functionality i want and insert the dex code to launch the service into MainUI class, then add my own dex from android studio into the apk and boom.
[Android Head-Units] TorstenH:
I figured out how to let the magic happen

https://xdaforums.com/t/junsun-v1-codes.4282299/post-88598875

But I'm wondering where are your modded MainUIs available?!
[Android Head-Units] jazzor:
They are not available, since Ive only modded it specifically for my car. However if you are interested in doing it I can give you assistance in greater detail let me know. Also, it would be great to see if you can get v81 apk to decompile but Ive had no luck with the latest apktools- it throws exception trying to generate the dex (smali).
[Android Head-Units] TorstenH:
But if your car is not unique it could make sense to share it.

I would be interested what's the best way to replace the existing MainUI.

a) install it as simple update by clicking on the apk?

b) replace the apk on system partition? Is this possible while system is running? Chmod required afterwards?
[Android Head-Units] jazzor:
There's a few steps.

1. After you make your modded apk you need to sign it using the testkeys from aosp.

2. Need to enable USB debugging in the setup menu

3. Boot into recovery using "adb reboot recovery"

4. In recovery, swipe down and right to mount system root

5. Prep a USB stick with your modded and signed APK.

6. Need to perform su and overwrite the mainui in system_root:

su @#zxcvbnmasdfghjklqwertyuiop1234567890,.
mount -o rw,remount /system_root
cd /system_root/system/priv-app/MainUI
cp /storage/udisk2/MainUI_modsigned.apk MainUI.apk

Replace the paths to your USB stick mount.

This is the only way I know to make the replacement APK "stick". Trying to remount the system as rw and replacing it in the live os will not write to the system root and reboot will remove your changes.
