Sorry, long post. Trying to explain some internals.

Marios script removes the cache in general (twipe_cache). I do not know if the twipe_cache only removes the "/data/cache" or also the dalvik program cache on our arm64 systems being "/data/dalvik-cache/arm64" and optionally "/data/dalvik-cache/arm32".

Next to that you also have the /data/data/ folder which can be removed in general with "twipe_data" (but you certainly won't do that for one app).

They can also store settings in /data/data.

FYT sometimes has a very awkward way of storing settings data for apps, and they certainly don't pay attention when doing upgrades with changed settings. Therefore they do a complete wipe.

Finally, some apps also store data in /data/app.

When you normally install an apk, also code is copied into "/data/dalvik-cache/arm64" being the dex files and the Android install process nicely takes care of everything.

Now again: I do not know if the FYT "twipe_cache" will also remove the dex files.

However, not using twipe_data during a (full) flash can really lead to issues in case settings have changed and the app does not take care of that during an upgrade (like said: the FYT apps don't).

So in earlier days when I created scripts for these "one app" flashes, and only for important system apks, I specifically deleted the necessary files as a "hard coded copy" of an apk will not do that (whereas a real install will do that).

And please note that I would not do this for any apk, but for apk's like the Settings.apk or the com.syu.ms.apk, I would (and I didn't either for the com.syu.ms on the sc9853i anymore)

So personally (and anybody: please don't take offense) I would not have used "twipe_cache", but have removed the specific files of the Settings.apk like:

So personally I would create a script like (and simply partly copying it from @mariodantas script):

And last remark: FYT (or actually their predecessors SYU) also store app data/settings in /sys/fyt, which is part of their old WinCE history. There is hardly no way to access that, not even on a rooted system.

FYT uses the standard Settings Android apk partly and modify it with the look and feel and their own data. I assume the "Google part" behaves as it should be allowing save updates or replacements, but the FYT part probably not. That's why I used in earlier days the "remove everything" for a certain important app before replacing it (and note that I never did this for music, radio or other apps which I used to modify)
[FYT Android Head Units] warpjavier:
I have been experimenting with my unit and I was able to dump all the partitions, even the super partition.

I grabbed a tool from XDA to unpack and recreate the super partition making product, vendor and system partitions RW and also resize them.

I still didn't try to flash the modded super partition back into the unit because if I mess up, I don't have an original FW from the manufacturer to recover.

On the other hand, I was able to flash a rooted boot.img and the oem partition directly without using AllAppUpdate.bin.

Assuming it works, is there anything worth changing in any of those partitions to make our units better?
[FYT Android Head Units] mariodantas:
Yes, the whole unit
[FYT Android Head Units] j0hn83:
Thank you for the detailed response.

However this isn't my issue as I installed the updated settings apk with twipe_all and not twipe_cache.

Seems it just isn't compatible with my mekede (116) unit while showing canbus settings.
[FYT Android Head Units] surfer63:
Not as such. The only nice thing to do is to go back from a super partition back to normal partitions, which would then make it possible again to write to all partitions instead of only the /oem partition.

This is also what @gordgelin (Vitaliy) did for his Vincent Vega mods (great movie) although his mods are for Teyes units.
[FYT Android Head Units] mariodantas:
@surfer63 great idea these lines of code

Maybe I'll add them to my fytfactory launcher installers !!
[FYT Android Head Units] AhmedScorpino:
Did you manage to solve the canbus issue with the new canbus box ?
[FYT Android Head Units] Specy01:
I'm sorry, but with this canbus I had no improvements, so I put back the previous one, that is the SimpleSoft XP
[FYT Android Head Units] vuvukalivu:
Hi @surfer63 , i having trouble when install Launcher on mariodantas. And show message on my screen. Any suggestions? Thank You
[FYT Android Head Units] mariodantas:
Well, surfer63 does not work with me, what's the problem here ?, on the 1st screenshot I see the launcher installed, what do you mean with 2nd screenshot ?, ,have you search in the system parameter for launcher ? name UIn where 'n' is the number ?

Sorry but your tag sounds like "Hi USA I have a problem with MEXICO, how to solve ?"
[FYT Android Head Units] vuvukalivu:
i'm sorry

2nd screen shot is your website, show that i take the luncher from your website.

the name of launcher : 190001033_1_com.android.launcher29.apk

after install launcher success and i take the usb pen drive, there is ino launcher install, only launcher 3 that install by the seller.

i repeat 2 times and the result is still the same
[FYT Android Head Units] AhmedScorpino:
Did you face the same problem of (no door information) with the simple soft canbus box also?

Did you tried the hi world canbus box like the Russian thread posted previously said ?
[FYT Android Head Units] Specy01:
No, I had the indication of the open/closed doors. I no longer had air conditioning and outside temperature and also messages. I would be tempted to buy the canbus HiWorld but I don't mind spending more money not being sure of the result.
[FYT Android Head Units] AhmedScorpino:
I now use raise canbus box PSA-RZ-15 and it had outside temperature but it had no air conditioning or door info or any other kind of messages and alerts

One technician once told me that you should try to update canbus software instead of trying various canbus boxes

What version of vehicle settings app do you have ?
[FYT Android Head Units] Specy01:
My vehicle setting is as in the picture.

It's much older than your version, but I don't know what it depends on or even if it can affect what the canbus shows.

But I think we are going too far off topic, before @surfer63 reproaches us immediately return to topic. Do you think it is normal to have as in the following photos attached 5 different versions of "lancher3"? And what does that 3 refer to?

If it can help, I use the UI22 home.

Edit:

Doing the various tests, I realized that depending on which car was set in the "vehicle settings" the temperature appeared or disappeared at, but also the time was automatically set properly or had to the time was incorrect. I think this will help some of the users.
[FYT Android Head Units] AhmedScorpino:
I think it's abnormal because if they are updates they should replace the original one

Did you try to uninstall one of them ?
[FYT Android Head Units] Specy01:
I too think that is not normal. I could try to uninstall one, but I would like to understand why I have 5 versions of the lancher if I have never installed it. Perhaps, when I mounted the M700S, I tried the various UIs to see the one I like goes the most, so I can supose that whenever it changes the UI, a new "lancher" was installed. But it does not seem to me to be normal behavior.
[FYT Android Head Units] AhmedScorpino:
Maybe this the closest theory for that

How do you know that the version of your head unit is m700s ?

How to know my head unit version ?
[FYT Android Head Units] surfer63:
You always see this "Launcher 3" in ALL of their launchers as these incredibly lazy FYT programmers do not change the strings.xml when creating a new "look & feel" launcher.

The strings contain all screen texts, but also the application name. They simply add a few new strings when they need them, but never clean up.

So in the resources in the strings.xml you will find as every 2nd entry <string name="application_name">Launcher3</string>.

So no matter whether it is the launcher 04, 05, 06, 10, 19, 22 or whatever launcher, it will always use the same name to present itself.

They do alter the package_name in the AndroidManifest.xml, so there you will find package="com.android.launcher10", or whatever number.
[FYT Android Head Units] Specy01:
I know I have an M700S because that's the one I chose when I bought it. I chose looking at the following table from the seller's site which is "NaviFly car-lyfe store".

Put here photos of the characteristics of your radio. Go to: SETTING - SYSTEM - ABOUT DEVICE and take pictures. And read the first post of this topic written by surfer63. Looking at the photos someone will tell you what device you have. I will not answer you for not TO write nonsense, i still do not feel safe to help

Edit:

Sorry @AhmedScorpino, I forgot to attach the table, I edited the post
[FYT Android Head Units] Specy01:
Can I leave them or is it better to uninstall any of them?
[FYT Android Head Units] surfer63:
You can leave them, but as they all have the same name, you never know which is which.
[FYT Android Head Units] AhmedScorpino:
All photos and properties i find in this thread is for horizontal screens

But i have a vertical Tesla style screen with the a similar theme like the horizontal screens in this thread

I red the first post and i know that all FYT screens have similar characteristics and this mine

Thank you for this idea. I now have the new Android Auto working (though I very rarely use it).

Does Google Assistant read your notifications in Android Auto? Mine does not.

Updating other newer files in the joying AllAppUpdate.bin has also got the new settings working on my unit though it looks a little different (back mic/front mic).
[FYT Android Head Units] taufikthexfader:
Always happy to share, happier if it also helps others..

Google Assistant works on my Wireless AA, sometimes instantly, other times slow respon. The only problem im facing right now is incoming calls cant output audio to my car speakers, i had to unpair bluetooth and disconnect AA entirely just to accept calls properly which is not ideal.

Maybe i will re-pair my bluetooth to my HU first, then re-setup AA again, i suspect it had to do with the permission to use call from my phone.
[FYT Android Head Units] gossipninja:
how do you adjust the time for the day/night backlight control?

In reference to the setting below (for some reason my canbus ALWAYS set the illumination wire "on" regardless of headlight condition.

Backlight control ( switches the leds behind the (soft-)buttons On/Off : or by switching on/off headlights, or based on time )

[FYT Android Head Units] daviddosa:
I went through the menu of my Mekede M300S unit today and put all the menu sections into a file with brief description on what each setting does if I know about it.

I highlighted the options unknown to me, but commenting is allowed on the document. If anybody know what that specific setting does, just suggest on that line in the file, and I'll change it in the document. (Leave your XDA username for credits later)

Here's the file: Mekede M300S Menu Structure
[FYT Android Head Units] surfer63:
Thanks a lot. I will check your list and add or correct them to/in the "FYT Settings Explained" in post #1 in case your list has better or more extensive explanations, or adds missing explanations. I will do that this weekend.
[FYT Android Head Units] daviddosa:
I have to say, that section I completely missed. I remember back when I joined this forum seeing something similar, but never found it again, and you just reminded me. Anyway, just look through it, and if there's anything worth adding to your, feel free.
[FYT Android Head Units] Petarkco:
Something interesting I noticed that on at least the Joying firmware RDS data from the radio is cached and not wiped during an upgrade. Seems a bit odd to not save presents with it.

It does create a problem though that if you have that cached RDS data and you go into another region with a station on the same frequency as in the data it will incorrectly display the wrong station name unless the other station has it's own RDS.
[FYT Android Head Units] j0hn83:
Can anyone tell me why my unit might be giving an error when trying to run the backup script in post #4?

I've ran the backup script many times in the past with no problems.
[FYT Android Head Units] PaY87:
Is there any official thread to follow the MD firmware listed in the OP? Its great so see somebody is putting things together for the community!
[FYT Android Head Units] Vlasp:
Have there been any efforts to log the results of "Print Protocol" with the CAN Bus messages to a file? I am trying to build a CAN Database file for my Civic and my headunit has CAN support, but just printing the raw messages on the screen makes it too hard to log them.
[FYT Android Head Units] daviddosa:
Have you tried using logcat, filtering the messages by application, and saving that?

I would think they dump that in the log files anyway, so it would make it easier to save it.
[FYT Android Head Units] blue_one:
Hi all, I'm interested in the pin layout of the ums512 module. Does anyone have some infos? Google wasn't helpful so far.

Cheers
[FYT Android Head Units] surfer63:
Check on 4pda for the 7862 (ums512) threads. They have multiple FYT wiring diagrams.

We are not allowed to link to 4pda.
[FYT Android Head Units] Jpw0917:
Has anyone created a tweak/ update that changes the Vehicle Settings app from Metric to imperial units
[FYT Android Head Units] dreamwave:
Is there a way to get the regular notification shade back on the Joying units? Does the "plain" fyt firmware still have notifications or are those removed there?
[FYT Android Head Units] surfer63:
Most probably due to a missing /oem/Ver.

I assume your zip is fine apart from thart missing /oem/Ver.
[FYT Android Head Units] surfer63:
Sorry. What do you mean with MD firmware?
[FYT Android Head Units] AvGear:
Can anyone give me some info, 8-Core CPU2*A75+6*A55 2.0GHz is this unisoc or Mtk?
[FYT Android Head Units] surfer63:
Read post #1
[FYT Android Head Units] AvGear:
Yes, I'm sorry about that. I have read it. The common that happens is 1.8ghz. It's just that the products sold by Chinese sellers are confusing to me. But it says 2.0ghz. I came here to confirm this information
[FYT Android Head Units] surfer63:
That's what you mean.

Yes, the new models like the M6 Pro from Mekede are indeed based on the new 2.0 GHz 7862 instead of the "old" 1.8 GHz.

Don't believe the Android 12 though. It is still SDK 29 so Android 10.
[FYT Android Head Units] AvGear:
Ok, because now there appears HU with MTK8667 2.0ghz with 2xA75 6xA55. And the seller just calls it 2xA75 6xA55 2.0ghz

Like this
[FYT Android Head Units] surfer63:
I don't know that Mtk one.
[FYT Android Head Units] marchnz:
Garbage avoid
[FYT Android Head Units] snaske65:
I know every one will say don't do it, but are there any kernels that can be overclocked for the 7862.

TIA.
[FYT Android Head Units] Pino1966:
Hello forum members, Happy New Year to all, I have a question, is advisable to carry out an MCU update, if it is already over a year old, I add a photo of my current MCU version. Thank you for your help
[FYT Android Head Units] surfer63:
You can do a firmware upgrade, but this is NOT an MCU firmware upgrade. That is something else and not depicted in your photo.

But if you don't have an issue why should you?

My firmware is from November 2021. I only updated my kernel with the October 2022 kernel, and I did not touch the MCU at all.
[FYT Android Head Units] bluemask69:
it's not wrong to update the mcu, you just have to find the right one (YIN), on 4pda you find many resources. I have updated my NOR mcu with no problems.
[FYT Android Head Units] Pino1966:
Thanks for your answer, do you also have a mekede car stereo, if so, could you send me a link to this MCU file, via PM
[FYT Android Head Units] surfer63:
What do you really want to update? Really update the MCU? Or the Android firmware on your unit?

Do you even know the difference?

If you want to update the MCU then show the version of your MCU firmware, not of your Android firmware.
[FYT Android Head Units] Pino1966:
I have already updated the firmware, what I want to update is the MCU, as I posted on the photo what, does it say that the MCU from 2021.10.09 is or did I read wrong
[FYT Android Head Units] surfer63:
I am sorry. You are completely right. I did not read the image careful enough.
[FYT Android Head Units] mastrv:
Still, why do you want to update the MCU? Is something not working properly? If all is working, there is no need to update the MCU. In fact, updating it may introduce other issues...and then you cannot revert to your current MCU.

You know the saying...If it ain't broke, don't fix it.
[FYT Android Head Units] Pino1966:
Hi, I still have the same problem that the car info is not displayed on the car radio, that is, temperature, rpm, fuel display and climate function are not displayed, have already replaced different can-bus adapters from raise and XP
[FYT Android Head Units] mastrv:
Are you talking about the Car Info app, the app? If so, that's controlled by OBDII dongle. I think the climate function may be the only thing not OBDII related...not sure. Also, watching that stuff gets old...I usually drive with Waze, for navigation, split screen with PowerAmp to play music.

There is a setting that turns display/control of the climate controls on or off, if I remember correctly. However, if it's a canbus issue, the only way to know for sure is if there is someone that has your head unit working successfully with your specify car make and model.
[FYT Android Head Units] AhmedScorpino:
I have a problem similar to @Pino1966 issue that is no car messages and alerts are displayed on the screen (l have a fyt vertical tesla style screen) installed in citroen c4 2007 with raise psa-rz-15 canbus box

But the SWC works fine with and the climate temperature info are displayed
[FYT Android Head Units] j0hn83:
I'm pretty sure things like RPM/Fuel display can only be displayed on these HU's through the OBDII port. Same goes for engine temperature.

External air temperature can be shown through the canbus only if your OEM stereo supported this and only if the car sends this via canbus.

That's the same for climate control functions. It needs to be something your OEM stereo supported.

Your Current MCU version will already contain the necessary info to support things like climate control.

It's the vehicle type you select in the canbus settings that is important.

For example my car has an OEM Amp, subwoofer and reverse camera. In order to get any sound and the reverse camera working I must pick the wrong vehicle (Hyundai instead of Kia) despite the XP canbus listing my car.

What car do you drive? Have you tried choosing similar carmodels in the canbus options?

I would be very wary about updating the MCU. I've only ever seen it fix 360 camera issues.

What car do you have?
[FYT Android Head Units] Pino1966:
Hi thanks for your answer, I have a VW Passat B5 built in 2003 and before my current car radio Mekede m600S, I had a Kenwood dab8019dbs, I only replaced the Kenwood because I have a smartphone Huawei mate 40pro and because no Google has services to support Android Auto, I got an Android car radio and because it is also more practical with an Android car radio. Only two functions work with the Mekede, steering wheel control and door display
[FYT Android Head Units] mastrv:
@AhmedScorpino What messages and alerts are you referring to?
[FYT Android Head Units] j0hn83:
Is the climate controls on that car not a separate panel on the car, below the radio? You won't be able to control that with the Mekede if it is not a function of the original radio.

The only 2 functions I have are steering wheel controls and reverse camera.

There is nothing to fix though as that is all the canbus sends.

Are you missing any functions from the Mekede that were on your OEM stereo? Or were you just hoping to add more functions?

Much of what you want seems to be info you need to take from the ODBII port with an app like torque pro.
[FYT Android Head Units] Pino1966:
Thanks for your helpful information, yes it's true, with my car there is a separate climate condition element under the car radio, is there a way to intercept the data of the air conditioner to display it on the Mekede, somewhere I saw at a video on YouTube that someone has it business with the same car model what I have, only the problem is, I can't find the video
[FYT Android Head Units] AhmedScorpino:
The OEM messages and alert that was displayed on the orignal car screen like when open doors or fuel level is low or place transmission shift Lever on P when parking etc.
[FYT Android Head Units] mastrv:
There are some settings to enable/disable display of car info. However, if those are on, then it probably means that your canbus doesn't handle those messages. You may need to select a different Citroen car model to see if that does anything as others have done. Search for Citroen and see what others have said. If anyone has the car make and model, they can provide their experiences.
[FYT Android Head Units] surfer63:
I tried to explain this earlier in post #616.

CANbus implementations depend on the car manufacturer and how much he shared messages for his CANbus protocol, next to the real basic commands which are the same for every car and defined in 1996/1997.

It also depends which messages are shared read-only, which are shared read-write, and which messages are strictly kept secret.

HAPPY NEW YEAR FYT-ters !
[FYT Android Head Units] AhmedScorpino:
I tried selecting other Peugeot and citroen models it and tried other raise canbus boxes and no result

But i tried another tesla style TS10 android screen with the same raise canbus box PSA-RZ-15 and all functions worked very successfully
[FYT Android Head Units] Specy01:
So it should be a problem of our devices. There will be some wrong setting or as you wrote in the post

Have you tried changing that false to true?
[FYT Android Head Units] AhmedScorpino:
Yes i changed it to true but no result also

I began to consider the words of the reseller that they disabled this function and maybe he was not bluffing and the problem isn't not this simple by changing value to true

Because he said that i should wait for an update file for that matter

Did you ask your reseller about this matter if he has a different answer ?
[FYT Android Head Units] Specy01:
I asked you because if I remember correctly, with the old firmware and the old canbus I had some message on the Device. But I'm not really sure
[FYT Android Head Units] dkowal91:
Friends I need help. I have an android M400S from MEKEDE, I wanted to update the MCU because in citroen c5 it does not display the outside temperature, which is transmitted after CAN.

On the MEKEDE website there are 2 versions of the software marked 9863-A11-9-10-220926.zip and the second one marked 9863-a11-wbt-9-10.zip. What are the differences between them and how can I check which one is correct for me? My English is poor, so sorry for mistakes.
[FYT Android Head Units] bluemask69:
wrong thread , your unit is a UIS 9863 not a 7862
[FYT Android Head Units] Specy01:
If I'm not mistaken the whole Mekede M series is uis7862 so it should be In Topic, but I could be wrong. @dkowal91, take a picture of the features of the M400S and put it here. While waiting for someone more experienced than me to respond, wait
[FYT Android Head Units] dkowal91:
unfortunately, I couldn't find a topic related to uis9863 anywhere, so I wrote here thinking that someone would help, and there are people updating mekede....
