Proud to introduce 7862 Kernel MD EDITION V1.0 with FMC (FYT Management Center)

This kernel coupled with FMC apk bring some functions like:

1-) Enable / Disable ROOT privileges on the fly (with SuperSU embeeded apk)

2-) Change system font scale (lack in the default settings)

3-) Make FYTBACKUPS (backup of OEM apks, auto generated AllAppUpdate.bin) and download them on the fly

4-) Backup of your /data/data folder (useless in this version but in upcoming versions you will be able to restore)

5-) Set autolaunch (at boot) apps like FYTStarter does.

Upcoming features:

Install : Uninstall FYT launchers on the fly

More ideas to come

*************************************

This Kernel is based on 6315_1 from 2022-10-27 Joying provided.You must add your own lsec6315update file to patch it

NOTE:

If you add lsec6315update newer than July 2, 2022 you will not be able to rollback to kernels before 2022-07-14, but if you add an older lsec6315update file you can rollback to any older firmware.

Check FYT Factory for download and more details.

@surfer63 if you do not validate this, I can delete !
[FYT Android Head Units] Battoussai:
Nice to have! Good work.

Any recomendations before install or it is brick free? :)

I have made a slight improvement detailed at the bottom of this post

https://xdaforums.com/t/medeke-navifly-7862.4248969/page-43#post-87792549

When I finally got a 5Ghz router to connect to at 3M away I connected at 490mbs and downloaded the offline maps I needed for Magic Maps very quickly.
[FYT Android Head Units] mariodantas:
Hi fellow, about MD EDITION, no worries but is always useful to have the original kernel apart in case you want to roolback to your kernel, thats all.

MD EDITION has been hardly tested before I created the post, I have many 7862 units and test it on all of them, it flashes flawlesly and I can rollback easy.

Abraço man !
[FYT Android Head Units] surfer63:
Very good that you create these possibiltiesdfor our units.

But I do not understand what you man with this latest statement.

If you ask me to check, I will, but I can't do that no earlier than Friday as I have a busy week.
[FYT Android Head Units] j-5:
It seems it doesn't work for me.

If I just unpack and repack, it works ok.

If I modify the 6315_1.zip with a different "apns-conf.xml" (only file I tried) it will report corrupt FW on any cold or warm boot and erase all my apps/configs until I restore the unmodified 6315_1.zip

@surfer63 : I tried one of those Joying Firmwares, it worked ok, but gave me the yellow bar. Edited the fyt.prop to be FYT=1 and saved it (it had a good amount of symbols in it) and the reflash wouldn't boot. Are manufacurers doing weird things to the FW now?
[FYT Android Head Units] mariodantas:
"Abraço man" = "Cheers fellow" in portuguese !
[FYT Android Head Units] mariodantas:
I did that and it worked flawlessly !
[FYT Android Head Units] j-5:
not sure what's happening here.

This is fyt.prop from Joying FW:

This is fyt.prop from 4PDA FYT=1 FW:

In the Joying, the characters don't render, and that's where I scratch my head.
[FYT Android Head Units] surfer63:
As far as I know there is no change in that. My first idea would be to do a fsck/checkdisk on the USB-stick.
[FYT Android Head Units] j-5:
I just used your script, it worked for purpose. No idea why my edits broke it, I used archive manager to open it and text-editor to edit it (ubuntu).
[FYT Android Head Units] raybriant:
hi guys, how to delete a system app for example waze from allappupdate.bin vital-app.

Can help me please to understand this?
[FYT Android Head Units] raybriant:
also how to set default wallpaper during update in config.txt file or in other section?
[FYT Android Head Units] surfer63:
Read post #1 and #2.

Also: read post #1 and #2 before even asking without reading.
[FYT Android Head Units] raybriant:
hi surfer63 nice to meet you. I have read the post #1 and #2 . I am asking if there is any way to add wallpaper directly on the update file? maybe with a script? About my first question, forgot it. thanks :)
[FYT Android Head Units] raybriant:
Maybe it is possible to do a script like radio remover, but for wallpaper pourpouse, somebody know how to operate?
[FYT Android Head Units] surfer63:
This is not the first question but another question which you only now ask, but so be it.

It is not possible to flash it as an additional file on your USB-stick. The wallpapers in the FYTs are part of the Launchers, they are packed inside as resources (and modifying those would be really a time-consuming effort).

The simplest thing to do is simply copy one (or more) wallpapers on a USB-stick, long-tap some empty position on your launcher screen, and replace it with one on your USB-stick.
[FYT Android Head Units] mariodantas:
As this thread is yours, I always like to ask you for validation, you can try and use of course and even submit new ideas, but to be honnest, here the most important part is to be able to enable/disable root on the fly and the font size that is not present in settings !

[FYT Android Head Units] j-5:
As far as MCUs goes, I'm assuming I need the MCU named the same as my MCU regardless of value of fytmanufacturer?

i.e., my MCU says PSTAR, but FYT=1, so I can't be flashing an MCU from say MCU NOR which also has an FYT=1?
[FYT Android Head Units] surfer63:
I added your "Mario Dantas Edition" firmware to the links in post #1.

Thanks for your continuous efforts to make the FYT units more user-friendly.

Edit: and added it to post #2 : I. (Factory) Firmwares.
[FYT Android Head Units] mariodantas:
Sometimes this logic do not work as expected, i.e. If you have MCU AYI (FYT 1 and others I guess) and want to flash the new NOR (FYT 1), the flash process fails but do not destroy the unit (hopefully).
[FYT Android Head Units] j-5:
ok, thanks.

Here's what I'm trying to figure out:

If I go to mobile network/settings, I get different results than if I long press the data button. On the latter, I show "connected" to my provider, but on the former, I can't connect to any provider despite 4 bars of 4G. So I'm not sure what the story is on that one. I've been flashing and tweaking trying to get that working for a time now (in between engine work, lol)
[FYT Android Head Units] Renval:

[FYT Android Head Units] jkister:
I have a SC7862 from Phoenix Automotive that HWget_info says looks FYT compatible.

Does anyone have experience updating the canbus firmware?

The home screen has RPM and MPH gauges, but the MPH doesn't work. Phoenix sent me a simplecanupdate.bin to upgrade using their instructions, but the progress stays at 0/0 after I press "start". Nothing at all interesting happens except that my steering wheel controls don't work after pressing "start" until I reboot.

Phoenix doesn't really know what's going on. They always reply, but it takes days for their next suggestion. Their last suggestion was for me to install their 190000000_com.syu.ms.apk and then try the update again, but the same thing happens.

Are there any logs I can look at, or some way to run this on a terminal to see what's actually going on? Or any other suggestions?

And thanks to this thread (I literally just read all 56 pages!) I found out why they have been having a problem getting my boot animation changed (I had a previous radio that had the infini boot logo and when I upgraded to this one it was just the google logo). They sent me a lsec6315update with a config.txt, but neglected any logo.bmp and bootanimation.zip. I'll be letting them know I figured that problem out, heh.
[FYT Android Head Units] jkister:
I just tried the code and it didn't go quite as expected.

I changed the lsec6315update because I was getting the error message about the original one being too old. No biggie I guess.

But when the script runs, it gets upset about the

/storage/sdcard1/7zzs a -r -tzip -mx=0 -p048a02243bb74474b25233bda3cd02f8 /storage/sdcard1/BACKUP/AllAppUpdate.bin /oem/app /oem/vital-app /oem/priv-app /oem/res /oem/Ver

The usb drive does have a ~312MB BACKUP/AllAppUpdate.bin, lsec6315update, config.txt, and updatecfg.txt. does that mean it worked even though it says fail?

I read something about a problem with a missing /oem/Ver, but mine does have the /oem/Ver.
[FYT Android Head Units] surfer63:
I discovered quite recently that the /oem/res is sometimes also missing. Also on my own unit.

The AllAppUpdate.bin is actually a password protected zip file. Use an unzipper to see what's in it. 312 MB seems too small indeed.

Edit: I mentioned a couple of weeks ago that I wanted to change my scripts to first check for some files and then include them (or not), but somehow I got corrupted zips. I will have a look again at it why that happened, when it is a bit less cold.
[FYT Android Head Units] surfer63:
User @jkister had a question which I unfortunately can't answer, but the series of Phoenix Youtube videos also showed how you can change between internal microphone and external microphone.

If you connect an external microphone, the internal microphone always continued to work. Due to different resistance level this caused interference which mostly made it even worse. Some nice tricks from Vitaly (@gordgelin ) on blocking the internal microphone can be found here.

But the Phoenix Youtube videos showed a nice alternative: that is, if it works. It's too cold right now outside to get into my car, but I wil try this in a couple of days.

More volunteers? :)

See this Phoenix YT video:

Sadly, missing option on Mekede 500S... so ribbon cable mod stands as the only solution.
[FYT Android Head Units] danilaur:
not find this settings in isudar v72
[FYT Android Head Units] surfer63:
It is not in the "normal" Settings apk. It is in an apk called "Car Settings" or "Car Info" or "Vehicle Settings" (my version) or something like that. It has a different name depending on the translation you use your unit in. It can have a "gear" icon or a "car" icon or a car icon with an "i" (for info), also depending on the Firmware version. My current version is a "beige" icon with a car on it and a blue circle with an "i" on it, but I am almost sure that on the May Firmware it had a different icon (and I can't remember the January firmare anymore).

And I think it only is visible if you have a CAN bus controller connected.

Edit: And in the video is it a blue icon with a gear wheel on it and called "Car Settings".
[FYT Android Head Units] warpjavier:
Thanks for a great thread full of useful information.

I have a couple of questions, I tried the search but I didn't find the answers.

I have the Phoenix Auto Tesla Style unit.

First question is if there is a way to enable Dark Mode to set, for example Google Maps or Chrome in Dark mode. I enabled the option in Developer Settings, but still does not give me the option in Google Maps.

Second question, Is there a way to make Car Link 2.0 to work in full screen with Android Auto? When I use AA, it only shows in a very low resolution and not in full screen.

Thanks

hallo zusammen ich bin aus der Schweiz und habe ein Problem.

ich würde gerne meine Einheit updaten den ich folgendes Problem habe,

ich habe im Bildschirm links und rechts ein Zeichen das ich nicht weg bekomme,

Links ist ein Info-Knopf und rechts ein Android, aber ich kann nichts machen.

auch wen ich drauf drücke passiert nichts, kann mir jemand eine Software schicken die dieses Problem nicht hat?

es handelt sich um ein Navifly 7862.

MOD Translation:

Hello everyone, I'm from Switzerland and I have a problem.

I would like to update my unit because I have the following problem,

I have a sign on the left and right of the screen that I can't get rid of,

an info button on the left and an android on the right, but I can't do anything.

Even when I press it, nothing happens. Can someone send me software that doesn't have this problem?

It is a Navifly 7862.
[FYT Android Head Units] surfer63:
Did you even search this forum?

Look at the thread "Android auto looks different. Is it normal?"
[FYT Android Head Units] surfer63:
English ONLY please. Read the stickies from the moderators.

The Android on the right side is the Toppal or Nexai AI voice assistant. You need to open the app "Toppal voice", so not the robot, and disable all options inside the app.

The left is most probably the assistant, although this icon is new to me. Open the Assistant from the program section and uncheck the options to diable it.
[FYT Android Head Units] warpjavier:
I searched for the Dark Mode which I didn't find anything.

Regarding the Android Auto, I searched for Car Link 2.0 resolution, and wasn't able to find anything. I'll look at the thread you mentioned.
[FYT Android Head Units] leo06:
Update to the latest firmware and is in factory settings. The latest firmware from joying also have it.
[FYT Android Head Units] Gscipione:
Do you mean this in the photo? Back mic?
[FYT Android Head Units] leo06:
Yes
[FYT Android Head Units] Gscipione:
I ask Medeke about this option and they told me to put it off.

I don't think that is the possibility to exclude the mic on board how is shown by @surfer63. This is what I understand from the Chinese but maybe they are wrong or don't know about this new option🤣. I will try to test it when I can to see the difference
[FYT Android Head Units] leo06:
I can’t test it because I already have disabled it with ribbon cable mode.
[FYT Android Head Units] Gscipione:
This is the respond from them
[FYT Android Head Units] thanos1234:
Awesome, good to know, I will also give it a try. I can also remove the external mic without pulling the unit out and see if it disables the internal mic.

Have you noticed any other changes to the latest firmware? Specifically if we can choose more settings for the CAM VIN reverse camera ? I installed a CVBS reverse cam that was laying around but regretably need to swap for a AHD.
[FYT Android Head Units] leo06:
Option for AHD camera was there with previous firmware.
[FYT Android Head Units] ludditefornow:
My Navifly default car info app has no button on screen to enter further settings. also the app looks like it can't scale as it only takes about about 60% of my 720 / 9 inch screen. See attached photo. Also no CAN info is forwarded to this app. No data is shown on this app.

Other apps register my correct speed so I am guessing there must be some hidden setting for Car Info.

Looking in another Rom (Joying), I found 190000000_com.syu.carui.apk and attempting to install. It noted as installed yet is not found in the app draw.

Does anyone have any car info style apps that I can try?
[FYT Android Head Units] warpjavier:
Just to confirm, there is no Dark Mode / Dark Theme option right?
[FYT Android Head Units] jkister:
How did you figure that?

Phoenix just sent me an update that contains the 6315_1.zip. Can I tell what version it is before I install it?

Poking around, I'm not seeing many dates/version numbers and 7zip has the files dated 2009-01-01 00:00

inside META-INF/com/android/metadata is post-security-patch-level=2020-02-05
[FYT Android Head Units] surfer63:
You have to follow my instructions as in post #2 Section III and more specifically III-a.

Inside the unpacked partition images you search for the "build.prop". For example in system it is in system/system. And inside the build.prop you search for the several build dates like:

latest Mekede from November

ro.system.build.date=Mon Jul 18 18:28:13 CST 2022
ro.build.date=2022-07-18 18:30:37 Monday

Latest Joying from 27 October mentions:

ro.system.build.date=Thu Oct 27 19:55:40 CST 2022
ro.build.date=2022-10-27 19:57:58 Thursday

(I left the utc build dates out.)
[FYT Android Head Units] surfer63:
Sorry. I was wrong. 312 MB is indeed what you would expect. In all previous models it was between 650 and 850 MB and even on the first 7862 models.

When they introduced the dynamic partitions the AllAppUpdate.bin shrunk to ~310 MB as "non-FYT" apps moved to system and product.

I guess I carry too much rubbish from the past with me ;)
[FYT Android Head Units] j-5:
The one I got from 4pda the allupdate.bin was 1.2GB :O
[FYT Android Head Units] jkister:
Has anyone seen a problem where all bluetooth devices show up as noName ? The icons are correct for their device type. Pairing does work. The same devices have the right names on my iphone.

It's been this way since I got the unit -- I did not break it by modifying config.txt.

I do see there is currently sys.fyt.bluetooth_type=1 and thought about changing it, but asking here first.
[FYT Android Head Units] Gscipione:
Finally I try it's option and work. So if you put off the mic built in will be automatically disabled and will enable the external one. I install last updated on the medeke site.
[FYT Android Head Units] roti86:
Cool, thank you for trying this. I installed the firmware that you shared last week yesterday.
[FYT Android Head Units] surfer63:
Yes. That is because they put again all stuff from the product and system into the Allappupdate.bin again, as it is not possible to handle that "normally" with dynamic partitions.

and in the end it doesn't matter. Dynamic partitions using system, product, vendor and "additional" software is simply a much cleaner way of being able to only update the necessary stuff via OTA. Even though FYT still simply releases complete firmwares.
[FYT Android Head Units] Gscipione:
Yes that one
[FYT Android Head Units] roti86:
Cool. So how does it work? If it is in 'off' status the back mic is off, only front mic works, and if it is 'on' just like in the photo back mic works only? Sorry, I can not try this at the moment, but I am curious :)
[FYT Android Head Units] Gscipione:
If you put off will work external mic
[FYT Android Head Units] j-5:
If it's on, both mics are active.

very,very strange !!!
[FYT Android Head Units] surfer63:
As far as I know it is an "On" and "Off" problem. The bug was alreadty there in 2016, and now it is 2022. It has been solved for the first time somewhere in 2021, and then came a new firmware and the contacts got deleted again. I really don't know.

Also Joying already mentioned several times that it was solved (see their blogs), and still their firmwares delete the contacts as well. But also a user mentioned: "This Joying firmware of xx-yy-zzzz works", and then again a newer version doesn't.

I simply do not sync Contacts. But then again: I hardly ever make or get phone calls in the car.
[FYT Android Head Units] danilaur:
if not sync with bluethoot i dont see name for contacts,i install now google agenda and i find all contacts in recycle bin,if you sync recent ,quick restore from recycle bin ! after 30 days google auto delet !!!

As for me, I connected the Huawei P30 phone several times) with Bluetooth, but I never shared my contacts (I don't like it). My son with his iPhone has shared them, but having this smartphone for a short time, he can not tell me if his contacts are saved on Google and also ICloud

[FYT Android Head Units] j0hn83:
Has anyone successfully added the new "use external microphone" option to a Mekede M500s?

I've updated my unit with the latest 6315_1.zip update from Joying but the option still isn't present.

I also tried Mario Dantas MD Firmware but that also didn't have the external microphone option.
[FYT Android Head Units] mariodantas:
nothing to do with the 6315_1.zip but with AllAppUpdate.bin, responsible apk is com.syu.settings
[FYT Android Head Units] j0hn83:
That explains it.

I was worried about flashing another vendors allupdate.bin.

I'll give this a try later.

Hopefully I can get my OEM mic working.

Thank you for the quick answer.

I flashed the Joying allupdate.bin from 11-08 and no option for mic.

1 shows the red/orange/yellow/green "guide" lines when driving backwards (why they call that radar?)

2 I am not sure but I think that if you have a front and reverse camera connected, and you didn't connect them correctly, you can switch them.
[FYT Android Head Units] surfer63:
I added a compatible DocumentsUI.apk to post 1 Q20.

Also added it to the bottom section of post 1 "Mods, useful software, tweaks....."
[FYT Android Head Units] mastrv:
@ludditefornow This is what I understand of them:

Some cars have rear radar/sensors...4 to 6 of them. The radar display shows which ones are sensing an obstruction and the distance. I think it uses colour to display distance. This radar display is visible when you put the car in reverse. Other cars do not have these sensors. This option toggles the radar display on and off.

I believe surfer63 is right about this. I think what this option does is after you take the car out of reverse, it displays the video from the front camera, if installed. I believe this is meant to help when parking. When you park, you sometimes alternate between backing up and moving forward to position your car in the parking spot. This option turns off switching to the front camera after backing up. I guess this is a preference thing.

I turned off the radar display when I back up as my car does not have those backup sensors.
