patched boot image for 2019-09-17 firmware

Please find attached the zip to root your SC9853i running the new 2019-09-17 release "9853i 1024X600 800X480 1280X720 2019.9.17.zip" (as of today 2 October 2019 not yet officially released).

Please note that after rooting the Google voice feedback doesn't work anymore, just like in previous releases.

Unzip the contents to a clean, empty Fat32 usb-key/sd-card and flash it on your unit.

====

Edit: And for those who want to unroot again, like I just did mysel as well.

See attached "20190917-normal-boot-image.zip"
[FYT Android Head Units] mclaudio:
can i?

hello !

can my unit be updated with that firmware and unrooted with this file?

thanks
[FYT Android Head Units] surfer63:
Your unit can be updated with this firmware, but not as it is now. You need to add one file to the usb-stick/sd-card BEFORE you flash it. See attached.

This will ONLY work if you have a non-Joying, but when it is compatible. It will first wipe everything and then do a fully clean install. After install the unit will really "think" it is a Joying.

Users having a Joying SHOULD NOT add this file for this 2019-09-17 firmware.

And of course: make sure you have a backup firmware from your own unit ready.

Your firmware is of 27 August 2019, so pretty new. Are you sure you want to do this?

And please think why you would want to root. Why do you need it and do you really need it?

Like I mentioned: I will most probably unroot my unit again. I see no need for it.
[FYT Android Head Units] mclaudio:
Thanks

Do you think it's best to have joking firmware?

I just need root to install the mods and be able to make AP with http injector.

What is your advice?

Ps. Only root without changing firmware how to proceed? Then can unroot easy?

[FYT Android Head Units] surfer63:
Why do you ask things again and again. It becomes annoying.

If you want to only root your unit, use the "howto: rooting SC9853i" thread, like I answered you before.

And yes, using that magiskmanager software you can also unroot again.

If you are so uncertain and inexperienced, then simply don't do it. Try to get more experience first.

Hi [MENTION=2550900]surfer63[/MENTION]

First, thank you greatly for your contributions to the android head unit community. It seems this field is not populated by many with the expertise and willingness to help as some other devices.

Second, after my attempt to butter you up with some praise, i have question on your hwinfo application and your opinion.

I ran the program on my head unit and it informed me that no fyt data could be found and to stop here.

Does this mean that the unit is very unlikely to be compatible with Joying root methods, or, is it still possible to wipe clean and trick it to think it is Joying?

I will post the .zip file as well if needed, i just didn't have access to my vehicle at the time of this post.

Thanks for your support in this forum.

To start with: I had nothing to do with finding the rooting method for this unit. That was completely done by a 4pda guy. One of the members of this forum "ported" it to this fourm.

Magisk Manager is (should be) a universal rooting method, so also suitable as such for your unit.

However, the specific way how the Joying/FYT units are rooted by flashing the boot.img this specific way, will most certainly not work for your unit.

It is indeed best to share the HWGetinfo.zip with this forum. If you are lucky you have an MTCD/E unit in which case there is expertise in another section of this forum, and there you have 2 rooted custom ROMs to choose from.
[FYT Android Head Units] andason:
Thanks much. I will share the file shortly.

Also, wasn't meaning to place credit on you for specific tasks, but, just your activity is appreciated as well as others obviously.

:)
[FYT Android Head Units] andason:
Attached is file
[FYT Android Head Units] surfer63:
I have really no idea what your unit is and whether it is compatible with some other model.

The manufacturer files are like

com.tw.auxin_bf95.apk
com.tw.ba_aa8e.apk
com.tw.bt_305c.apk
com.tw.carchoose_3f18.apk
com.tw.eq_936a6.apk
com.tw.music_a41e.apk
com.tw.radio_78cc.apk
com.tw.service_a5a4.apk
com.tw.tv_f39c.apk
com.tw.video_869a.apk

So it seems it comes from Taiwan instead of one of the Chinese factories.
[FYT Android Head Units] andason:
Thanks very much for checking. If you or anyone else have any thoughts on where to look, i would appreciate any info.

I would love to look at rooting.

Help

Hi, guys. Help me please. I need datasheet for dsp chip: BU32107EFV
[FYT Android Head Units] hellkaim:
Hi.

I have the joying 1-DIN 1280x600 unit with the following firmware:

post-build=SPRD/sp9853i_1h10_vmmTos/sp9853i_1h10:8.1.0/OPM2.171019.012/37210:user/release-keys
post-timestamp=1568688501
pre-device=sp9853i_1h10

So as I understood to get ROOT on it with use of Magic one have to take his firmware from Joying, use a native 6521_1.zip stripped down to just 1 main boot.img with altered /META-INF/com/google/android/updater-script. The updater-script itself has to be modified to only push boot.img to the device.

I created several versions of that altered 6521_1.zip that are flashable but the result is a black screen. Each time I have to re-flash stock ROM back to get device going. Where did I missed something? I indeed tried to use original 6521_1_input.zip carefully following the guide with the same result. It might be that when I was extracting my boot.img on the head unit the file got corrupted somehow, but Magic did not complain and did it's job dropping out patched boot image....

Thanks in advance.
[FYT Android Head Units] mclaudio:
hello

i followed all the instructions

it rebooted and detected the update...but then only a black screen

what can i do?

i followed all the instructions, only changed the name of the patched boot image to match the name on the instructions
[FYT Android Head Units] mclaudio:
i have exactly the same result as you...

ad to install again firmware and loosed all settings :(

damn
[FYT Android Head Units] surfer63:
You now created your patched boot image. You are the only person who can do that as it needs to happen on your unit as it is different than the Joying ones.

If Magisk Manager made this patched boot image, the boot image should be correct.

Now we can check what is in that 6521_1.zip and maybe help you. Please share your 6521_1.zip with us with the patched boot image.
[FYT Android Head Units] mclaudio:
thanks

here all the info

https://drive.google.com/drive/folders/1jdHLqmuIbw1Ko2fYOUDlqkxbbmUo1ghv?usp=sharing

note: i had changed the name of the patched image file...the one generated by magisk is magisk_patched and on tutorial is patched_boot
[FYT Android Head Units] surfer63:
You did everything correct, but your zip misses the following two files:

META-INF/com/google/android/nvmerge
META-INF/com/google/android/nvmerge.cfg

I do not know if that causes the error.

I redid the the zip creation, almost 100% equal to what you did, but with those two files.

See attached. No guarantees at all!

Feel free to try, but you might have to reflash again if you get again a black screen.

So basically we need additional files in order for the boot image deployed correctly? Do I understand right that when the ZIP file is signed the hashes for certificates inside the archived files will be updated?

Thanks!
[FYT Android Head Units] surfer63:
It still didn't work. [MENTION=2358025]mclaudio[/MENTION] posted 2 pictures and then a pm. That doesn't make it clear for the others.

My version didn't work either.
[FYT Android Head Units] hellkaim:
So we can assume there is no working solution for last firmware?
[FYT Android Head Units] surfer63:
No working solution for your non-joying unit. The last fimware plus rooting works fin on the Joyings. There is something different on your units.
[FYT Android Head Units] hellkaim:
The problem is I have a unit from Joying based on SC9853i with the following firmware 9853i 1024X600 800X480 1280X720 2019.9.17
[FYT Android Head Units] surfer63:
In that case you should have read this thread better, as it is only 3 pages back, or searched better. I created a rooted flashable zip for the 2019-09-17 firmware. See post #191
[FYT Android Head Units] davekra:
So, I'm hoping someone can help..

I have the Joying JY-VO101N4GS-R Android 8.1.0 Automatic Rotatable Screen

https://www.joyingauto.com/joying-a...tatable-screen-car-audio-system-4gb-64gb.html

I first flashed the 2019.9.17. Then I followed the rooting procedure and everything was fine. The couple apps I'd installed weren't listed so I thought I'd delete their directories on internal storage.

I think I deleted the Magisk backup of my boot image or something and I can't seem to flash firmware anymore.

The system is fully bootable but I'd like to wipe everything and get back to stock to start over.

When I plug in a flash drive, it reboots like it should but I see a quick flash of the Android guy with a red triangle with the words "No Command". It then boots back into the OS.

How can I recover from this? Should the firmware be able to put everything back to stock?

Looking in the firmware .zip I don't see an updatecfg.txt. I added one with twipe_all but it still won't update.

Thanks,

davidk
[FYT Android Head Units] andTab:
Thank you. Rooting worked like a charm.

Hello all

I tried rooting my device and it seemed to have work but after using a check root app it seems it failed however, the Magisk app was installed on my device.

The root checker said I have version SP 9853I instead of SC as listed.

Joying extra tools runs incredibly slow on my device. I'm not sure what I'm doing wrong. I just want the no kill mod

EDIT: Solved my problem, Magisk wasn't fully updated so it was causing havoc. After updating all is well
[FYT Android Head Units] djdwest:
Hey everyone! I finally got my unit how I like it.

Im running the 2019-07-17 firmware.

I have:

Rooted my unit

Installed JET

Changed the radio skin in JET

Done the no kill mod in JET

Then removed root

My issue is at some stage after rooting I lost the audio focus (no sound) on the fm radio app after deep sleep.

I need to click the back button, and reload the app to get sound again.

Has anybody else had this issue or have a fix?

(I have tried search but I'm also following 3 or 4 different threads for this unit and there is so much information lol)

Cheers
[FYT Android Head Units] surfer63:
That has to do with the nokill mod. Upon going to deep sleep the mcu also mutes the radio audio channel. And normally the radio app is also killed.

With the nokill mod the mcu still mutes the radio channel, but the radio app "stays alive".

But the radio app does not have any radio functionality of itself. It is nothing more than a "remote control" towards the MCU that handles the FM-chip and audio.

So ending the app will mute the radio audio channel (but it was already muted), and restarting the app will activate the radio audio channel.
[FYT Android Head Units] djdwest:
Cheers thanks for explaining that Surfer :) Gives me a few ideas on how to fix it!

Hi there.... and Thank You very much for the information about how rooting SoFia 3gr, i have a Peugeot 206 (1 din head unit on bottom + 10¨ touch screen on top separatly). I did the root following your instructions and everithing is OK. I can see the root folder and it is OK. But i have a problem and i would like to know you can help me:

My unit adverts Open doors and Close doors, by a top view of a gray generic sport car. I wish to change this car and put a top view of a car like my car. I want to know the file or files i have to modify or change... I hope you can help me.

Regards...
[FYT Android Head Units] surfer63:
You mention you have a SoFia 3gr?? In that case you are completely in the wrong forum thread.

I do not have Android 6 apks anymore, but if you unzip the canbus apk, you will find inside the "drawable-nodpi-v4", lots and lots af images including *door* images. In the 8.0 (PX5) and 8.1 (sc9853i) they are all .webp images. I think they are still .png images in the Android 6.0.1 version.

Replace (some of) these images with your own, and rezip the canbus apk.
[FYT Android Head Units] hellkaim:
I will contribute to all reply. The unit has 2 boards: the "low" level with Radio, GPS, Bluetooth\WiFi, USB, Audio etc. and a "high" level board on which Android resides.

So as you can understand there are a lot of linkage and "drivers" needed in Android to work correctly with the lower board.

Hi

I bought a device from Mekede. Can I upload the upgrade from Joying and thus get root. The devices look identical when it comes to software. Is this operation impossible?
[FYT Android Head Units] colonel_lp:
To be honest I have no idea, if the mcu's are the same then maybe, but you might brick your device. Hopefully someone else might know more.

You could try the same method to root your boot.img and flash that.
[FYT Android Head Units] surfer63:
The device might look the same and might be a FYR compatible, but do not use a boot image from another device.

The first post of this thread describes exactly how to create your own rooted boot image.

Secondly: Use the HWGetinfo apk from my signature, to check at least whether you have a FYT compatible.
[FYT Android Head Units] miszaq2:
I was thinking about completely replacing the software on my device

send on priv HWget_info
[FYT Android Head Units] surfer63:
Your unit is indeed a FYT compatible. That does not mean you can use the boot image from [MENTION=2328357]colonel_lp[/MENTION].

It is best to create your own boot image if you want to root your unit.

But why do you want to be rooted?

rooting is not because it is possible. rooting is something you do because you need it. My previous units were rooted. I did not root this 9853i because I don't need it.

And why do you want to completely replace your software? Your firmware is of 08-11-2019 (8 Nov 2019), which is pretty new and further 100% identical to the Joying Android software.

MCU software and boot image might be different. But everything running on top of that is identical.
[FYT Android Head Units] miszaq2:
Hi again

Thank you for yours time...

First: If I understood correctly, the instructions for making your own boot images are in the readme file in the developer directory , yes???

Second: Why a want to be rooted??? Becouse I need to modify several settings on my device - e.g. the map saving path for Tomtom, and many other demanding root.

Thirdly: if I change the software in the future I will be able to use the update from Joying - unfortunately my manufacturer does not expect it

Fourthly: not all things work for me - including a reversing camera - I exclude connecting cables - I rather think that the problem is in the software, besides, Joying software can be further modified with various additions
[FYT Android Head Units] surfer63:
OK. Reasons enough :)

Note that the MCU firmware might be slightly different because your components might be slighlty different. The MCU communicates between the Android layer and the "non-Android" hardware layer.

So if you are going to do this, make sure you have a complete firmware for your Mekede as backup.

Is that platform fully compatible with Joying SC9853i?

Hello,

I bought a new Android HU and I see its specs of the platform totally the same as Joying. Can anyone check if Joying SC9853i FW of May at least will be compatible with this platform or not. Attached snaps from the platform.

Thanks!

Your images are not visible until we press reply. Then the code shows up with the URL. Although it might seem the functionality is there, it is not. You need to attach images via the button below your post.

Anyway: Your unit is a Zhan. It "should" be compatible (the PX5 Zhans are also compatible with the Joying PX5s), but we guarantee nothing (the standard disclaimer: we can not be hold responsible .....)

Also: Try the HWGetinfo from my signature. It will give some more details and will also immediately report to the user whether his/her unit is compatible.

Hi,

I collected the dump from HWgetInfo app and seems to me similar to joying platform attached. Can you double check and highlight any see risk to use the FW. As usual it is on my own risk :mad:

https://drive.google.com/open?id=1-chB1kwX8Sf-R4xmMKOMqruogEVgNhqt

Thanks
[FYT Android Head Units] surfer63:
Did you attach a Joying HWGetinfo, or your HWgetinfo? You are now confusing me.

So do you actually mean:

Anyway: the fyt properties in the attached file differ slightly from my Joying properties.

Note that I am definitely not an expert on motherboard details.

For example. Mine says: [ro.fyt.boardtype]: [LF]

Yours says: [ro.fyt.boardtype]: [LW]

Does that mean the motherboards are different? And does that mean you need different MCU firmware? I really don't know.

So can you use the Android firmware: probably yes.

Should you also flash the MCU firmware? I really don't know.

So if you want to try, make sure you always have a backup firmware from your own unit, so you can flash it again.

And if you only want to root it, you can definitely use the method from post #1. That will work.
[FYT Android Head Units] mashrom:
Thanks,

I checked the ro.fyt.boardtype in properties.txt mine is [LW] not [LF]

Anyways, propably I'll need to root at the moment and I'll use Joying_Root_9853i_1024X600_2019.3.29.zip where my platform resoultion is 1024X600. However, the date in your zip is a bit older than mine that is 07-05-2019 if I got it right would that cause any trouble?

Thanks Again!

[FYT Android Head Units] surfer63:
Sorry, you are right. I switched them. I will update my previous post.

Do not use that one. It will most probably cause issues like a possible boot loop. I said: "Use the method" , NOT "use the zip".

Create your own boot image based on post #1. See the developer.zip for "everything" including a Readme.
[FYT Android Head Units] mashrom:
Ok I'll do the insturctions in the document and will get you back.

Thanks!
[FYT Android Head Units] surfer63:
No idea, but I really have my doubts that rooting your unit will help in this case.

rooting has to do with authorisations, and apk and user rights, not with system functionality.

Hey there

i got a new Device (Tesla Style) and i want to get rid of some annoying things and need Root.

It has a Intel SC9853i CPU but when i checked with HWGet Info it told it is not an FYT Device.

It is kind of this Device https://www.amazon.co.uk/android-Ve...gation-WIFI-player-2G16G-An9-0/dp/B07WX1HM1N/ and there are more Sellers like Isudar who sell it.

When i google about root with this CPU the only thing that shows up is this Thread - is there someone who could help?

The actual Firmware is here

Thanks Rooting succeeded finally :D

Now playing around to get BT recognize OBD and use the USB modem hopfully I can!

Thanks again for your support surfer
[FYT Android Head Units] surfer63:
HWGet doesn't give info about the "identity" of the unit. It is definitely an Android 8.1 but the reseller is trying to make it look as an Android 9.0, but that's the cheap mtk version.

In short: I have no idea what it is.

But the described method for the SC9853i unit in this thread, is actually an almost general approach to root 8.0/8.1.0 units. Simply keep the firmware at hand to reflash your unit if the rooting fails.
[FYT Android Head Units] hurks:
Thanks for your answer.

So if its not working or something happens i can install my Firmware always?

I have no Recovery Mode - only in the Settings there is a "Flash" Button.

The main Reason for me is the annoying big useless Top Bar

At my old Tesla Style Radio the Top Bar was hidden when i started a App but at this Radio it wastes the Space and some Apps work not correct because they don't recognize the missing Space.

Are there Methods with root to hide it?

And yes of course its 8.1 with the new Update it shows Android 9 but this is Fake
