I took your advice, and I wrote to the manufacturer who sent me a new firmware, saying to try to update the radio.

This is the contents of the folder on Onedrive.

The two files highlighted in red scare me.

If I open them I see some strange text.

Content of File number 1 (Config.txt)

Content of File number 2 (write in chinese)

I'm afraid that the files contain Chinese characters that my windows system doesn't recognize, and when updating the android radio it will cause a failure and cause the system to loop.

Is it a well-founded fear?

Do I need to take any precautions before proceeding with the radio update?
[FYT Android Head Units] Wallace8956:
This the contents of the files if I open them with notepad++.

How do I proceed at this point?

Do I launch the update, or do I have to take some precautions?

I don't want to loop the system
[FYT Android Head Units] DaddyFinger:
2 is update "instructions" or "notes", or something to that effect.

Line 4 = Bluetooth type; Lines 5-9 are ... well ... the types. You're supposed to enter the correct value 0-4 in Line 2.

Line 12: 0 = no 360, 1 = with 360. You're supposed to enter the correct value 0 or 1 in Line 11.
[FYT Android Head Units] taufikthexfader:
I tried it, but I like PeaceOS much better.

Assuming you still have original fyt.prop and config.txt, just flash AllAppUpdate.bin of PeaceOS with your own fyt.prop and config.txt with flash_any_allappupdate script from the first page...
[FYT Android Head Units] taufikthexfader:
any line with # will be ignored/skipped...
[FYT Android Head Units] DaddyFinger:
Thanks for the tip, it's not about which is better though ... I'm just curious about the additional folder named OEM in the download, and the 4 apks in it - It wasn't in the Oct 2022 update.

I'm on a Dudu unit with 1280x720 MIPI screen, but I am running on the Joying Oct 2022 update because stock Dudu firmware is Chinese-only without option to change language to English, so for me it was more of a necessity. Joying's Oct 2022 firmware worked plug-and-play without any modifications at all.
[FYT Android Head Units] LLIyT_HuK:
This was my PeaceOS update patch. But not for everyone it worked adequately, so I made a separate assembly of the firmware. Everything was fine with the folder name, maybe the one who posted it changed something.

I did not need all occurrences of the name, I changed one folder with the application in the mod to another. It wasn't universal for everyone.
[FYT Android Head Units] LLIyT_HuK:
Files from the OEM folder will simply be transferred to the internal user memory of the device, without installation. Feel free to delete.
[FYT Android Head Units] corey_s:
Any chance that you can share this EKIY firmware with me, I have nearly the same unit and wouldn't mind having a copy as a backup. PM me with details if you can.
[FYT Android Head Units] bukeyolacan:
Can someone inform how can I run this unit at home (not inside car)? I apparently need some power adapter but i have no idea about it. If possible, can you link the item on aliexpress etc.? Thanks.
[FYT Android Head Units] LLIyT_HuK:
Any power supply for 12V and from 1A.
[FYT Android Head Units] bukeyolacan:
Thanks but how do i connect it into that power plug of the device?
[FYT Android Head Units] Matt Devo:
I have a bench test setup for the units I resell, just chopped up a spare harness and spliced into some banana plugs connecting to a 12v power supply. To power on the unit, you just need +12v on the yellow and red wires (pins 2/3), and ground the black wire (pin 1). You can also wire up anything else you want to test, such as illumination, reverse, speaker output, etc

Hi,

Is there a way to change the other widgets of any launcher (Not the PIP App) to something else ?

Thanks.
[FYT Android Head Units] surfer63:
Yes. You need to modify the launcher.
[FYT Android Head Units] abd alaa:
May I ask you if there are instructions to do that ?
[FYT Android Head Units] I[E:
@surfer63 has a pretty in depth post about doing it.

samplerwrcPL said:

On the 4pda forum someone posted a script to replace the BT Dialer

I installed this patch. The update was done ok but the application does not start - I only have a black screen. What could be the reason? I have the original software from the radio. The original folder looks like this: /oem/app/190002001_com.syu.bt"
[FYT Android Head Units] surfer63:
Didn't you read my reply or didn't you understand it?

It is now double installed on the unit and that's why it doesn't run at all.

It would have been better if the script contained "rm -rf /oem/app/19000*_com.syu.bt"
[FYT Android Head Units] samplerwrcPL:
Of course, I read and modified the script before installation to delete the folder like in my system, i.e. /oem/app/190002001_com.syu.bt and only one proper set was installed /oem/app/190000000_yl1920_com.syu.bt.
[FYT Android Head Units] surfer63:
I assume the _yl version is dependent on other system libraries and system hardware (the BT chip) as the extension _yl is used for a couple of yl850 apks which heavily rely on the new hardware, which is not in the older units.

The _yl dialer uses the new qualcomm BT chip. You do not have that one.

Better reinstall the old BT app.
[FYT Android Head Units] DaddyFinger:
Hi all,

So I'd flashed my unit with the Joying 15 May 2023 update. Everything runs fine.

However, it seems installing launcher from @mariodantas' FYT Factory doesn't work now? Or at the very least, it seems it doesn't work if it's a "UI4" because it does not overwrite the stock UI4. I tried a "UI6" as well and it does not overwrite the stock UI6. Or did I miss any setting after the flashing?

I'd tested installing 1 which is "UI20" and it works, so I guess it's just not overwriting the stock launcher.

Hi All, I'm newbie here, may I know, how to enter recovery mode on mekede m6 pro plus 2k, I have tried reinstall firmware from mekede, but dts in equalizer had gone, it's just show normal without dts, or it that firmware not come together and need to install with other zip file?
[FYT Android Head Units] LLIyT_HuK:
Before replacing, you must clear the data of the dialer application. And this is not yet a guarantee that the application will work, for this reason I did not upload the patch to the public, it was only in the Telegram channel of the PeaceOS mod. As a result, because of these problems, I assembled a separate firmware assembly with this application sewn in.
[FYT Android Head Units] surfer63:
You can't enter the recovery mode.

Did you read post #1 and #2?
[FYT Android Head Units] sheren1902:
Maybe too many, confused already, by the way, thank for your reply and u know about dts in equalizer, how to solve it, I try go inside firmware, but didn't see the dts, not really sure which one are equalizer,
[FYT Android Head Units] tesna:
I think I have FYT unit (branded as Nakamichi) on mine. It has 2000x1200 screen and it works great! However since it has 16:10 ish screen the android auto layout seems strange, instead splitting left and right it splits top and bottom which does not look good (at least from my perspective). The apple carplay layout is fine. How do I make android auto splits right and left? tried to change the dpi setting from factory menu but no effect.

Btw, my unit came with zlink5. I tried head unit reloaded and the android layout is pefectly fine on there, but using HUR is not as seamless as using zlink5 so prefer to keep using zlink.

How's everyone android auto layout with 2000x1200 screen?
[FYT Android Head Units] ducthang83:
i think this is not FYT device but some MTK chip and not suitable for this post
[FYT Android Head Units] ducthang83:
The mekede yl850 has a different dsp39 than the dsp55, you should check with the manufacturer carefully for it to work perfectly.

I'm looking for a way to change the radio app on the side buttons? I don't really want to get involved in flashing new firmware, although I have done that with phones and tablets. Any quicker options?
[FYT Android Head Units] surfer63:
Change to what? Another radio app or a completely different app?
[FYT Android Head Units] modelman1968:
I want to change it from the installed FM radio app to my DAB radio app.
[FYT Android Head Units] surfer63:
Use the modded com.syu.ms from @seb21 or my FYTHWOneKey (see my signature below).

The modded.com.syu.ms is still under active development and has more options. My apk is "easier" to install but I no longer maintain it.
[FYT Android Head Units] Ragpuss:
I have a Tesla style head unit fitted to my 2014 Jaguar XF and have just loaded this firmware along with that from Mariodantas it is mostly going well although I'm having problems with a few advanced settings.

My question is, I have a setting in the main menu called Passive Insurance does anyone know what that is ?

Also, since fitting this unit, I can't turn my heating off, I can turn the fans down but there is no button anymore to be able to switch it completely off, I think this is likely a Jaguar only issue but has anyone come across this and resolved it ?

I'm trying to work out the button remapping program but it's slow going and I'm not even sure if the heater off can be mapped ?

Thank you in advance for any help :)
[FYT Android Head Units] marchnz:
Hi new member. Enjoy your time having a read through forums, you might event find these questions have been asked and answered a number of times.

Enjoy. RtFF.
[FYT Android Head Units] Ragpuss:
I did do a search but nothing relevant came up unless I did something wrong of coarse :/
[FYT Android Head Units] DaddyFinger:
Hi all ... I had an issue which turned out to be a setting I assume I’d set previously (I can’t remember it) but got wiped during the flash to the Joying 15 May 2023 update. I assumed it was a problem with the firmware, and I tried PeaceOS, which faced the same issue … I later realised what the issue was and set it correctly.

However, due to curiosity and (no offence, please) PeaceOS isn’t quite for me … so I decided to revert to the Joying firmware, but at the same time try some modifications:

Unzipping AllAppUpdate.bin and deleting UI4 and UI6; default launcher in config.txt was changed from UI6 to UI13

Deleting the stock Joying Radio and Music folders and replacing them with the ones from PeaceOS (if this is something frowned upon, I apologise, but it was for testing purposes)

I repacked this AllAppUpdate.bin using WinRAR with compression set to “Store” and put it in my USB stick along with the other files.

And I got the config.txt read file fail + loop again 😭

I tried several variations, but nothing worked … kept ending up with the same thing.

I then decided to try 1 last thing - download 7Zip and used that to repack AllAppUpdate.bin …

… and it worked 😍

Conclusion: WinRAR works only with unzipping … I can unzip firmwares and AllAppUpdate.bin files with it, a firmware update directly unzipped into a USB stick using WinRAR without any modifications works … WinRAR just isn’t working correctly (at least, for me) with the repacking of AllAppUpdate.bin. For this repacking, it really is best to use 7Zip as stated in @surfer63 ’s guide.

So I currently have the Joying 15 May 2023 firmware with PeaceOS’s black-and-white stock music and radio apps, and I am able to install / uninstall UI4s and UI6s from @mariodantas ‘s site. All seems stable for now … will monitor for a bit.
[FYT Android Head Units] hasani19:
Hello @surfer63 , can I use ANT wire for powering up my fan (i.e. could this 12V output power up my fan current-wise)? The fan I bought to install on my unit is a 70mA ball bearing fan, as it was advised here... The reason for asking this question is that my unit has two wiring harnesses, the one that has ground (required for fan -) also has ANT wire and the AMP wire is on the second wiring harness. So, aesthetically, it would be neater to use both (+) and (-) from one wiring harness. (I know I wouldn't see wirings after installation, I'm just curious to know if ANT could be used for this purpose but I can live with using AMP wire). Thanks

Update: I checked the voltage on both "AMP Ctrl" and "Antenna" wires; as it was mentioned by @old.splatterhand and @surfer63 , Antenna wire had constant 10.25 volts (obviously reference point was ground) regardless of "Antenna normally on" status (on/off) in the settings ; However I could turn on/off "Amp Ctrl" but this wire also had 10.25 volts! I thought maybe I'm doing something wrong by hooking multimeter's common to the ground going to the unit, so I touched the multimeter's comm to ground on the board (visible through one of those holes for 4G antenna or something) but still got 10.25. Car battery voltage was 12.01. I hooked up my fan to car battery and even the noise coming from fan was noticeably louder, meaning it was spinning faster compared to its speed when I used Amp wire. So at this point I have to stick with @LLIyT_HuK recommendation and just use ACC.
[FYT Android Head Units] LLIyT_HuK:
Why not just take ACC?
[FYT Android Head Units] hasani19:
Because, connecting to ACC, the fan would be always on with the unit, but using one of those control wires from the unit lets switching on/off the fan from the head unit using corresponding settings (as it's proposed by @surfer63); And I found it useful because my unit does not get very hot unless I'm using both Music Player and Navigation app. So, I don't want to always hear that "hum" from my dashboard (even if it's hardly noticeable since I've installed a PWM module to control the fan speed; couldn't find a silent fan with decent quality) when listening to piano or other slow instrumental tracks. Thanks for your suggestion anyways.
[FYT Android Head Units] hasani19:
Hi all, while waiting for your valuable answer to my previous question I have another question... I opened my unit to install an active cooling, now when I wanted to assemble it back I noticed that some thermal paste was applied to the back of Amp IC. The IC package is mounted into a little housing (heat sink block) on the backplate, the question is should I reapply thermal paste (considering that I don't have one at my disposal at the moment), if the answer is yes regardless of the fact that I should clean the old one (which is not actually old, the unit is a brand new, haven't been installed yet) what is the correct way to apply new thermal compound, since the IC slides in that housing.

Attachments: Picture 1: Power Amp IC location on the mainboard, Picture 2: Heat dissipation block on the backplate

[FYT Android Head Units] old.splatterhand:
Is it possible to switch ANT wire on/off?

As far as i know, you can do this only with the AMP wire.
[FYT Android Head Units] surfer63:
As far as I know this is correct.

The ANT on/off switch is as far as I know for those old electric antennas that could slide out/slide in into the car.

So first off: this would not work.

Secondly, if this would work: It would also work like the ACC wire: sliding out the antenna on ACC (switching on your fan), and sliding in your antenna (switching off your fan) when ACC is disconnected nad the units takes some time to power down everything.

Hello,

I've received a link from Sinosmart for a new firmware update. I don't know how to check the kernel date but it seems that the AllAppUpdate.bin is created on 2023-08-14 20:12:32

Sinosmart August 2023 FW Update
[FYT Android Head Units] Clandaries:
For me the link does not work
[FYT Android Head Units] rockman18:
EDITED in my previous post...
[FYT Android Head Units] hasani19:
Thanks, that makes sense, although there is an option for turning on/off "Automatic Antenna" in the settings but I've not tested if that could power ANT wire with 12V, I'll test it with a multimeter and I'll update my post.
[FYT Android Head Units] hasani19:
Actually you were right, but the other problem was that Amp voltage was 10.25 volts for some reason! So, I just use ACC to run my fan.
[FYT Android Head Units] marjanoos:
From my experience in PC building, YES, you should reapply the thermal paste. Why?

There could be some small air bubbles if you would try to insert pcb without reapplying. You could also try to reuse this paste (take it away with some small blade, credit card etc and reapply).

About the correct way, I don't know to be honest. I think I would just use alot of the paste on the IC itself and then just put it all inside the "cooling room".

This is correct , best to clean the old one, one can use alcohol , then flood the housing about halfway up , then insert the case/chip.
[FYT Android Head Units] easyguy:
Saw my answer in the wiki, thanks!
[FYT Android Head Units] hasani19:
Thanks. I actually, did that before receiving an answer, because I thought the same way as you did. I just hope I have put enough of that thermal paste, because that block was a really thermal paste-hungry "cooling-room". I almost added like 3 pea-sized glob of thermal paste into this chamber and spread it with a spatula. I also applied a 1mm-thick layer of the same paste to the back of the IC. I was almost confident that the paste would leak out but nope, it was actually enough to fill the gap between the IC and the inside wall of "cooling-room" at least from what I could see after putting the board into the backplate. Whether that amount has been enough to make an even contact between IC and the housing is just a matter of time to find out! Because it was impossible to see through the block after putting the board back in.
[FYT Android Head Units] hasani19:
Hi all. Can I add new apps to "app" folder in AllAppUpdate.bin instead of "vital-app" folder. My ROM missing a system app "com.syu.carmark" that changes boot screen logo, I've already changed my boot screen logo using "lsec" method, and I know I can put the APK in "vital-app" folder, but I'm just curious to know since this is a system app accessible through settings, adding this APK the same way factory default apps are managed (e.g. renaming APK to full package name: 190001002_com.syu.carmark.apk and put it in a folder with the same name in "AllAppUpdate/app") could mess up something or no? I'm trying to make a modified version of default ROM to include/exclude apps I need/don't need. Thanks
[FYT Android Head Units] LLIyT_HuK:
Yes!

In the APP folder, applications will be "system".

From the folder Vital-App will be installed as "third party", with the possibility of removal.
[FYT Android Head Units] hasani19:
I got you. So basically, adding those apks to "app" folder is safe, right? I just might not be able to uninstall them (that I'm not planning to do so) like a normal app

Powered antenna wire if I’m not mistaken would bet a one shot (maybe 5 sec On) when unit is powered up then again when powered off to bring it back down. Why not use amp wire?
[FYT Android Head Units] hasani19:
Thanks for your answer. I just hooked up my fan to ACC, because for some reason both my amp and ant wires had a voltage of 10.25v with respect to the ground. Depending on how much I would be able to ignore the fan noise, I might use amp wire to power up a relay that feeds ACC to my fan, that would be a solution for my case.
[FYT Android Head Units] old.splatterhand:
With this Fyt units, this could be the case (maybe others too).

With all my other car radios i have had the last 20 years, the ant+ wire delivered constant power as long as the car was running.

Hi guys,

Iv searched hi and low on here but cannot seem to find what i want. I have a android 10 7862 system with FYT management centre i want to completely reset my unit to factory. When i do it via the unit option FYT stays on.

How do i delete FYT management centre off my unit? Im sure i seen a thread on here how to but cannot find it at all.

Any help would be appreciated

Thanks

Is it OK if I remove "190000000_com.android.calculator2" from "AllAppUpdate.bin/app"? I'm planning to install HiPER Calc, so I don't want to have two calculator apps, and because it was impossible to uninstall the default calculator, I wanted to use a custom AllAppUpdate.in that the app is removed from it. It's even impossible to disable this app or force stop it, does the operating system rely on 190000000_com.android.calculator2 that its termination might cause malfunctions? I honestly didn't think so but I was afraid removing the app would break something in the system. Thank you.
[FYT Android Head Units] surfer63:
Yes, that can be done, but why bother? You have space enough on your unit.
[FYT Android Head Units] surfer63:
Take the fmc installer. It starts with removing the old one and then install the new one.

Simply outcomment the lines that install the new and then flash it.

Been away a while, just came back to see this, @surfer63 - nice work!

I'm going to have to come back later and read up on it, I always loved Mario's work and was sad he didn't have time for it anymore (hope things get better for him soon!).

One of the things I always wanted was a backup/restore that actually worked, he never finished / fixed that. This looks really cool though and glad to see the project isn't dead!
[FYT Android Head Units] Saffy79:
Thanks..

I want to install the new

thanks surfer63..

So i just need to down load the fmc installer let it run to uninstall.

I dont understand when you say outcomment lines that install new?

Sorry to sound thick

I just checked mine and looked it up, you are correct, the power is constant. The limit switch on the motor shuts the power to the motor off when it's all the way up.

Hi all. When I edit "AllAppUpdate.bin" (By extracting it as a Zip file and then add/remove my 'vital-app's), what settings should I apply in 7-Zip in addition to setting this password: "048a02243bb74474b25233bda3cd02f8" and putting compression ratio to "store". I'm asking this because when I unzip and rezip the same original AllAppUpdate.bin, the size and properties are slightly different. For example "version to extract" is "deflate+store" in original file and dictionary size is 32KB. I'm afraid patching a wrong file would cause any unwanted effects.

How can I run the command explained here:

I've already installed 7-zip but "zip" is not recognized as a command either in CMD or Terminal. How can I run this command? Sorry, if this is a stupid question! :)

Picture1 - RIGHT is the intact original AllAppUpdate.bin and LEFT is the zipped archived from the same extracted files without any modifications with 7-zip settings as shown in Picture 2:

Picture 1

Picture 2

UPDATE: I don't know if it was really a problem, but I solved this inconsistency issues by using Total Commander as it was explained by tyukhta in 4PDA forums (and it was a pain in the neck to understand those google-translated texts). The "packer" used for packing AllAppUpdate.bin should be set to ZIP2.0, which you can do in Total Commander. There's a video also (again all Russian language with no narration) showing steps to modify AllAppUpdate.bin.
[FYT Android Head Units] 03hdfatboy:
when you create the

When you save it as a PW protected.zip just re-name the ".zip" to .Bin
[FYT Android Head Units] hasani19:
Thanks for your reply, but still the size differs by a few bytes and version to extract remains "store" instead of "deflate+store". Doesn't it matter which "Encryption method" I use, there are two options, ZipCrypto and AES-256, what about "path mode"?
