The default main server apk kills all apps when going into deep sleep when ACC_OFF is triggered.

Internally it has a whitelist of apps that should stay running, but furthermore all apps are killed.

This functionally is triggered by one single line calling that specific "KillAllappsBut" method (function) that does this killing.

The NoKill versions simply disables this one line function call, so that every app that did run will stay in memory, be it your mediaplayer, your navigation app, or whatever other application.

"Joying JY-JO002N4" got successfully root on it.

many thanks.

first I flashed "9853i 1024X600 2019.3.29.zip" to be safe

and than

flashed "Joying_Root_9853i_1024X600_2019.3.29.zip"

would be nice to have root for "9853i 1024X600 2019.4.3 Bluetooth.zip"

Will the rooting help on pairing OBDlink LX device?
[FYT Android Head Units] surfer63:
No, that has nothing to with rooting. It has to do with the bluetooth drivers.
[FYT Android Head Units] welaish:
Thanks! But what is the benefits of rooting?

I used to have a headunit with 4.4 it was working perfectly with the BT obdlink Lx it's dead and now I bought the joying 8.1 and I cannot get thr obdlink to work nor the USB cable. What is the catch here?
[FYT Android Head Units] highkick05:
Yeah at this point, I've narrowed it down to being 2 settings files

customs_appid.properties:
appid=b99c74bae38c52ae
token=2d3893452746535fef63a651

fyt.prop:
ro.fyt.ccbwin=0
qemu.hw.mainkeys=0

^ not sure why these files enable the newer steer.apk to actually work within the old UI

and the addition of the new UI 190043002_com.syu.steer.apk this seems to allow the HOME, FM & AM keys to trigger the actual Home and Radio action within the old UI. Has nothing to do with the ms.apk (both files same)

The UIs I am playing with are 9853i OS 1280X480 Old UI 2019.11.28 \ 9853i OS 1280X480 New UI 2019.11.28.

Going to open both steer apk's within Eclipse and view the differences.
[FYT Android Head Units] highkick05:
But, as you say split screen is Android functionality. I think the newer steer.apk is what is messing with the old UI 50/50 split screen. I would really love to just be able to open the old steer.apk in Android Studio or something and figure out what is happening and where the HOME FM & AM functions are pointing within this apk. Because it doesn't look like they work correctly.
[FYT Android Head Units] surfer63:
Most FYT apps use a totally incompatible layout scheme derived from very old PC and extremely old no longer formally supported Android java layouts. They work, but that's all. That is also why they need to create firmware versions for the several resolutions deviating from the standard 16:9.

Some of the very new apps do support split-screen. The rest doesn't as they are totally outdated crap and the developers never bothered to migrate to the proper Android layouts.

I have asked them multiple times since 2016, as it is not that difficult, but they either do not understand me or refuse to understand me (I think the latter).
[FYT Android Head Units] highkick05:
So I read this further; the link to github json, the stub-release.apk is no longer a valid link. Not sure if this effects it. But then you have the audio mixer problems after root, and someone saying its because the Magisk root method does not finish correectly. I'd be so happy if someone fixed the audio mixing issues. I would probably keep the root then. Having Waze not give directions on top of poweramp or radio running at the same time is probably a major requirement for most Joying users. I've given this my all, I think I will give up and go back to stock :cry::ROFLMAO:

Having said that I've practically made my own custom firmware now, editing txt's in the syu.ms.apk + adding apk's to the Allapp. Chaning config.txt ro.fyt.launcher=com.teslacoilsw.launcher (Nova launcher) and flashing that to the HU. Presto, full wide screen use, only downfall is the old syu.steer.apk doesn't map the HOME + FM + AM buttons to my eBay steering wheel controls. But I have splitscreen 50/50 now Oh well I will live with this! will check back to see if any more progress has been made in the future - perhaps a new firmware release ! thanks guys
[FYT Android Head Units] mastrv:
The link still works. I tried it. You have to change hxxps to https.

If you can modify the firmware to make your own custom firmware, as I did, you can add and remove apks as needed. Why don't you replace the old syu.steer.apk app with the one you want?

I also initially had root and found several issues occurred with root. I decided to go stock, with my own customizations, and then to use alternate methods that could make changes to the firmware without actually rooting the head unit. What do you need root for?

You should have a look at the thread about Modding without root: https://xdaforums.com/t/modding-your-joying-fyt-sc9853i-unit-without-root.3974357/
[FYT Android Head Units] highkick05:
stub-release.apk link is not there within the json file on the link you pasted been removed from the github.

The non-root alternative method was the first methods I used, before I tried to root the unit.

The syu.steer.apk is the one that fixes the HOME , FM & AM buttons on my eBay steering wheel controls. However, it is from the new GUI firmware and corrupts the interface, giving a 66/33% splitscreen that is unfixable and looks lopsided. I could just flash that using the non-root method, though I choose not too.

A more full proof rooting method is needed.
[FYT Android Head Units] mastrv:
Sorry, I misunderstood what you were looking for regarding to magisk.

If you go to https://github.com/topjohnwu/Magisk/releases?page=2 and look at Magisk Manager 7.5.1, you will the stub-release.apk for that particular version of magisk. The URL for it is https://github.com/topjohnwu/Magisk/releases/download/manager-v7.5.1/stub-release.apk so you can update the json file to point to that file. Not sure if that would be correct, but I believe so. You can always try it and let us know. Worse case, you can reflash the previous firmware.

Note that since these are all pointing to resources that can be removed or changed at any time, this means at some point in the future that can happen.

For the steer apk, not sure what you mean by 66/33%. When I run my steering apk, I run it full screen and not in split screen. In any case, I can split the screen at 50/50 or 66/33.
[FYT Android Head Units] highkick05:
how do you set the Split screen and adjust the portions of screen apps takes up? that's weird never done that for me.
[FYT Android Head Units] surfer63:
I would not flash that one. Why flash a version that is 2 days older? I guess it is 100% the same.
[FYT Android Head Units] mastrv:
By default, all my apps run full screen unless I'm already in split screen. I start split screen by first starting one app, then clicking on a 3-vertical dot icon in the top right of the status bar. Here's a picture that isn't my car, but this is what it looks like:

I can then move the bar in the middle slightly and the screen proportions change to 66/33 or 33/66 depending on which way I move the divider. When I press the 3-dot-vertical icon, I'm presented with a list of recently opened apps to select run in the 2nd app window. So if I run Waze first, it opens full screen, I press the 3-dots to select PowerAmp. If it's not there, I press the home icon, and start PowerAmp from the home screen. It fills in the right half of the screen.

Some apps are not designed to run in split screen with a smaller window for display. Sometimes a message says that. It will still run but some controls may not display or thinks might be too compressed.

To get out of split screen, I just drag the divider all the way to either the left or right edge. That won't stop the app, just brings the remaining app to run in full screen. So if I'm running Waze and PowerAmp and then slide PowerAmp off the screen, the music keeps playing. Or if I slide Waze off the screen, it's still telling me directions and when I go back to it, it's still navigating along my route.

How do you do split screen?
[FYT Android Head Units] weasel18:
Is there one that's compatible with my version?
[FYT Android Head Units] surfer63:
Don't bother. They stopped updating after April 2020. The units are already out of support.
[FYT Android Head Units] weasel18:
Are you saying don't bother rooting? I assumed they stopped supporting it since I hadn't seen any recent versions, recently. So I'd figure I could then root it with out much worry of warranty void.
[FYT Android Head Units] surfer63:
You were very short in your first post. I only thought you wanted to flash the 20200407 firmware.

Yes, you can use that 2020407 rooted boot image. But I don't root my unit anymore. It brings nothing extra that you can't achieve also with available tools.

What's more: You loose tts voices in all those navigation apps and other apps that use TTS.
[FYT Android Head Units] weasel18:
I apologize. I realize now how that did sound. I left some info out haha. mainly I want to root to see if I can update build.prop to a slightly more current device model and id like to tinker with Apple Musics Dolby Atmos feature in my car as i have a DSP and time delayed.

And I can't resize (no root and Joying Extra tools not working) or overscan (wifi adb unauthorized and impossible with not really OTG usb A port) and I want this to installing the joying 8.8 in my Corvette.
[FYT Android Head Units] forgivegod:
Its not that hard. See this for how to do it on Android 12 + OTAs!!!!! :) , https://xdaforums.com/t/read-this-before-updating.4356219/

Essentially,

1 - install magisk onto some android device

2 - get the firmware from whoever you bought it from, flash your device and make sure it works

3 - keep that firmware and open whatever zips you find until you locate the boot.img

4 - use magisk to patch that boot.img

5 - swap out the patched file for the boot.img file in step 3 (rename to boot.img)

6 - rezip everything exactly as it was (dont create new folders in the zip...i did the first time, perhaps you did too)

7 - flash your device again with new zip

in some cases 7 might fail, and you will have to resign the boot.img . see here : https://xdaforums.com/t/signing-boot-images-for-android-verified-boot-avb-v8.3600606/
[FYT Android Head Units] highkick05:
Then enjoy your new rooted / or gone back to original firmware which won't matter anyway because your audio mixing won't work anymore because its not rooted/patched the system correctly.

I've done all of the above man. Sound will only work with the app you're using. i.e. voice won't work with Waze while listening to music
[FYT Android Head Units] forgivegod:
Ahh yes. Good thing I have the later UIS7682 model. Either way, I never did voice command anything on my old airmont. I'm more button oriented (tasker).
[FYT Android Head Units] highkick05:
Yeah... hows the functionality on that thing? So you've rooted that succesfully, does the audio work well across all apps after rooting ?
[FYT Android Head Units] forgivegod:
Like a champ. Is the most fluid device I've seen. I never noticed any issues on the airmont either. Again, I dont care for voice command anything.

Working in hacking the radio app to a decent color/skin. More on this soon.

I wish I knew where you got stuck, like error message or something. I feel like I could figure out whats missing
[FYT Android Head Units] forgivegod:
I powered up my old intel headunit since the new UIS7682 is now installed and decided to see if I could root it. It took a couple of attempts but what finally worked was:

- creating an android virtual device on an intel machine using the x86_64 android image on API 27 (android 8.1)

- installing the latest magisk on that AVD and use it to patch the boot.img (from the 2020.4.7firmware)

- stuff the patched boot.img into the 6521_1.zip and then run the signing proess/tool on it

- take the new 6521_1.zip and put it and the other firmware update files on a usb stick and flash

I have root. Tho magisk is complaining about signature verification. Might have to install mods manually. No biggy.

Don't confuse things here.

This is the sc9853i thread. That user asked if he could root his uis7862. He was in the wrong thread, but I pointed him to marios kernel as he asked for a uis7862.

If you have a sc9853, you can't use that kernel.

If you also have a uis7862, you are also in the wrong thread (but then you can indeed use mario's kernel)

Would you mind helping me out to unroot my device?

I did the root like 4 years ago and forgot everything about it :(

Its installed in a fun car I'm rarely using these days, so I have not much interaction with the joying anymore.

not sure if I ever used it properly, I used macrodorid to kill the radio app I guess and I might've managed to keep the android alive when switching off the ignition with all apps showing up again right after starting the car again.

not sure if that was something the rooted boot image did on its own o_O

but yeah I think it's just annoying not being able to use Google Maps crash-free and with TTS, which is just because it's recognizing the root, correct?

I have a custom FCC interface I'd like to keep, but the rest is not that important I believe...

Is there an easy way to get rid of the root to have maps working properly?
