Thanks, but I didn't root or modify anything. I wouldn't know how to neither. I don't have any update files etc. My USB drive is not even recognizing any USB sticks anymore despite being power on. I'd have to fix that first.

I created a new thread for "FET". See here https://xdaforums.com/t/fet-fyt-extra-tool.4653315/​

Hi guys and girls,

As fmc is not around anymore, and being ill this entire week giving me a 1~2 hours a day that I am not exhausted, I decided to pick up an anbandoned "piece of work", being my FET programme (Fyt Extra Tool).

This is a very basic, "ugly" tool. If nobody is interested I most probably stop again.

If users are interested ....

Anyway some screenshots inside the spoiler (Click images to see fullscreen)

Spoiler content hidden.

Buttons with "the android with root on its chest" require root access.

The 3rd screen is a "Dutch" screen. I started to make translations, but that took too much time. For some languages I can almost do it completely myself, for others I do not have a clue. If you want it in your language, you do the translation. :)

Dear translators (whoever): Please take the strings from the attached zip. DO NOT use the strings from a decompile apk. It contains a lot of garbages from the other libraries built in.

See attached the current languages, but only very partially translated (using https://www.deepl.com/translator).

And attached the apk. Simply install it as any other apk (no lsec script, just plain install)

EDIT: Latest apk version in post #3707.

Edit: Note that the first ZIP option is only for non-Teyes FYT devices, but no system/error checking yet.

Edit2: You first have to set a pincode before you can lock the screen. No error checking there either.
[FYT Android Head Units] LLIyT_HuK:
Great replacement for FMC! I would also like to add a login button to the standard Android settings =)
[FYT Android Head Units] surfer63:
Sorry. Which standard Android Settings?

Isn't that the button ?

Or do you mean something else?
[FYT Android Head Units] LLIyT_HuK:
Aha
[FYT Android Head Units] surfer63:
I created a new thread for "FET". See here https://xdaforums.com/t/fet-fyt-extra-tool.4653315/​

Button added. "Default Android Settings screen".

(Sorry, from Dutch screen: my default) Click Image for full ize.
[FYT Android Head Units] newuzer1:
Does the above systemsettings.apk @LLIyT_HuK posted also need to be installed? or is that already integrated into the mekede firmware, PeaceOS, or this FET apk?
[FYT Android Head Units] j0hn83:
No it doesn't need to be installed. The systemsettings.apk is just an app that's a shortcut to the (hidden in FYT) default Android settings.

@surfer63 has added a button to his FET apk that does this.
[FYT Android Head Units] Tibi1977:
Hello! I would like to ask for help. I have an Android head unit (from China) that arrived in error. My question is, what else can I do with it, or is it trash? It says fast boot mode and doesn't go any further from there.
[FYT Android Head Units] j0hn83:
You aren't giving us much to go on.

We could throw you a dozen different firmware types and hope 1 is taken by the head unit but with some firmware being multi GB in size that's not practical. There's probably hundreds of different types of head units with different processors that all take unique firmware.

Do you have a manufacturer/model name or number? Anything at all to help identify the unit? It surely didn't come in a blank white box. Some description of what the specifications are or a picture of the rear wouldn't hurt.

Even knowing the exact processor inside and with a picture of the rear of the unit it could still be a half dozen different platforms that all take very different firmware formats that are completely incompatible with each other.

You need to help us to help you.
[FYT Android Head Units] Tibi1977:
Sorry for the lack of information. I ordered from Ali. What I know about it: Nedehe s100, 8 cores, 2GB ram, the processor is Unisoc UIS8581E. I am attaching the pictures of it. Thank you very much in advance for your help, sorry for the language inaccuracy, I am using a translator.
[FYT Android Head Units] gordgelin:
probably flash memory is dead, that's what those no command and fastboot errors usually indicate
[FYT Android Head Units] Tibi1977:
So there's nothing you can do about it?
[FYT Android Head Units] gordgelin:
you can contact seller/go to service
[FYT Android Head Units] j0hn83:
You can try flashing a firmware but if it doesn't try copying it then the units flash memory may be dead.

I've had my unit in fastboot mode a few times and recovered it successfully each time but mine was due to a failed firmware/kernel flash and not a hardware issue.

FYT units are almost impossible to brick from an incorrect firmware flash.

Looks like you have this unit https://a.aliexpress.com/_EQ7QbDf

Try putting a firmware/kernel on a clean FAT32 USB drive and insert it in to the head units USB port.

You could use @surfer63's Optimized kernel for the UIS8581E, along with an lsec6316update file and see if it flashes.

You may need to press the reset button a couple times to get the unit to look for the firmware.

Failing that return to sender.
[FYT Android Head Units] Tibi1977:
I tried about 70%, it goes away, then restarts and starts the update again
[FYT Android Head Units] j0hn83:
Try the latest Mekede firmware for your SoC, screen size and resolution.

MS9863-a13-wbt-9-10.zip

1 file sent via WeTransfer, the simplest way to send your files around the world

wetransfer.com

Put all the files on the empty sd card

I've no experience with dead flash drives so I don't know if it's failing at the point it tries to write data.
[FYT Android Head Units] Tibi1977:
Unfortunately, it does the same thing with this one
[FYT Android Head Units] olemann96:
I have a bit of a buzzing sound in certain places when I drive. It clearly picks up some signals. Anyone have any experience with this?
[FYT Android Head Units] j0hn83:
Does anyone know how to change the language of the firmware flash screen?

I had been running a Chinese firmware for a while and now that I've gone back to stock firmware I noticed the flashing screen is still Chinese.

The green message advising to remove the USB after flashing.

I'm not holding my breath.

Can you tell me how to turn on the video from the rear view camera on the widget? When reversing, the camera works, but I want it to

the video was displayed when I was driving forward. I am adding this application in the settings on the desktop, in a picture without a video.
[FYT Android Head Units] rickthecabbie:
I had to open Nove settings from the app drawer as soon as it is available. At the top of nova Settings you will see an orange banner telling you that Nova is not your defau;lt launcher. Click on that orange banner and it will take you to the menu inside Nova that lets you set it as default for real.
[FYT Android Head Units] Jp230:
Is there a way to replace the graphics of the generic car for the door status?
[FYT Android Head Units] surfer63:
Check the Modded FYT 34 launcher thread and search for the FrontApp to change what is in the PIP window.

Not entirely correct and already a very long issue on these 78626 and 8581 units. As long as you have the Google WellBeing app installed (removed from my and Mario's kernel), you will always go back to the Stock launcher, no matter whether you set Nova or whatever other launcher as default launcher.

Yes, Change the CANbus apk and replace the graphics.
[FYT Android Head Units] rickthecabbie:
I am simply relaying my experience, which is that Nova Launcher takes over the default Launcher settings. Again, this is what has worked for me multiple times. I understand and respect your opinion, and the fact that you have contributed all of your findings to XDA. This is how we all learn so to say that my information is not correct casts doubt on my work. If you would like, I can make a video of my technique for dealing with this issue, but I've been here long enough that my word should be enough.

EDIT: To be clear I am not out for a flame war or any controversy, Mostly I just want to be clear that my findings are repeatable. As is the motto of The Royal Society. Nullius in verba, Latin for "Take nobody's word for it". So, don't take my word for it, Give my method a shot and if you find different results, GREAT! Please post your findings and we can know that there might be more than one way to skin a cat.
[FYT Android Head Units] surfer63:
I am certainly not out for a flame.

Do you use a kernel from Mario or from me?

Before the removal of the Google Wellbeing app, I certainly could set Nova as default launcher, but any time the system/Google Wellbeing "felt otherwise", it set back the launcher to one of the builtin launchers, while Nova was still the default launcher.

This is also due to the fact that when you select the Launcher in the FYT Settings, you can only select a FYT launcher. If you do it via the standard Android intent to select the default launcher, you can select any installed launcher. I guess that FYT Setting and the standard Android intent clash with each other if also the Wellbeing app is installed.

Hi, I didn't find any information about my problem. I have a LEHX L6PRO head unit (7", UIS7806, dual 4G sim, 3 USB), a few days after installing it and putting a SIM card in it, the 4G signal disappeared, it shows the empty 4G signal icon.

I tried without success:

> Change 4G antenna.

> I used different SIM cards, from different providers.

> Factory reset.

> Connect an antenna to the "4G-" pad, which does not have an SMA connector, only the pad on the PCB.

Comments:

When I open apps like "Network Cell Info", it closes automatically.

I took measurements with a multimeter and the connector where the antenna originally goes "4G+" has a very low resistance <2 Ohms, the "4G-" connector gives an open circuit. They both go directly to the IC.

Any help is extremely appreciated.

Those with Nova Launcher, anyone get a spitscreen app combo to come up on startup? I can get Tasker to launch apps in splitscreen and I have shortcuts on the desktop to launch app combos in splitscreen. It will launch both apps but splitscreen doesn't happen when starting but if I click the task shortcut it works fine. I tried having Tasker's App Factory convert a task to apk but that just fires both apps up but no splitscreen.

Any suggestions.
[FYT Android Head Units] surfer63:
split-screen-launcher. I use it in combination with Nova.
[FYT Android Head Units] surfer63:
You are in the FYT sub-forum and your unit is not a FYT. The users here have no knowledge of your unit and can't help you. Please head over to the General Head units sub-forum.

The only thing is that you might try is to change the IMEI. That is: if your type of unit supports that.
[FYT Android Head Units] newuzer1:
I see this in the latest Mekede build.

I assume moving that to another firmware (PeaceOS in my case) is not as simple as copying the cpufan.apk?

There's a whole bunch of other files in the lib folder alongside it (right panel above). I'm admittedly clueless when it comes to packing/unpacking/libs/odex or whatever happens with an installed .apk which might explain why I may have asked a stupid question.
[FYT Android Head Units] Robbo69:
Just bought an EKIY T900 4/32. Does anyone know the password for Developer Options? I tried 7788 but it comes back with incorrect password. I contacted the seller who advised that Developer Options is only for factory technical staff so they would not tell me.
[FYT Android Head Units] ptuchik:
Try 681232
[FYT Android Head Units] gordgelin:
this is valid for teyes, for other brands password usually is 3368
[FYT Android Head Units] Robbo69:
681232 and 3368 are passwords to Factory Settings (on Teyes and general FYT respectively). I need the password to Developer Options (from the System settings)
[FYT Android Head Units] gordgelin:
you have to access developer settings via settings (NOT android system settings) - 3368 should work. android settings can have different , unknown password
[FYT Android Head Units] Robbo69:
That works! Thank you - I was coming at it from the wrong direction.
[FYT Android Head Units] siravata:
first you need to unblock access to the developer options, and then enter the password 3368 when entering the developer options. I had this.
[FYT Android Head Units] Tibi1977:
Does anyone have an idea how to solve this, or is this impossible?
[FYT Android Head Units] thugscorpion:
Please note that the UIS8581A only supports a maximum of 4GB RAM.

Everything above is probably cached from/to the slower eMMC.

I cannot find a legit source for a datasheet telling me this SoC supports more then 3-4GB.

Bocsi, de google fordítót használok, a chrome kinevet, hiába írok angolul, magyarul jeleníti meg, direkt nem csinálom, ismerem a szabályokat,

Mod translation: I'm sorry, but I use google translate, chrome laughs at me, even if I write in English, it displays it in Hungarian, I don't do it directly, I know the rules,
[FYT Android Head Units] surfer63:
You need to switch off Auto Translate for Google Chrome. simple as that.

If other users know how to do it, you should be able as well. Basic knowledge.

Before I go through the firmware (7862-A11-9-10-22.9.26) again from the beginning, does anyone know how to help because iGO_Luna does not appear in the Current Launcher App and does not play in any launcher I put it in ? a while ago he saw it and ran it normally in the launcher! now it only runs google maps. Look at it Video.
[FYT Android Head Units] hal752:
Hi all.

Just need to understand a few things.

Order a 7862s mainboard FYT.

The unit is completely stock and will be hooked up to my 13 inch display. Seller has already set my display drivers as it's resolution is 1920 x1200.

I have seen a few videos sent by the seller and it has the realtech Bluetooth chip and DSP 15.

For example apart from teyes can I install firmware from mekede and others aslong as I change my device to reflect theres?

Thank you
[FYT Android Head Units] thugscorpion:
Is the rooted kernel for 8581 universal and can I use it on my none FYT radio to get root access?

In my case the brand is Ruancheng.

Mainboard K421 V1.3 with the K4811 unisoc UIS8581A

I also wasn't able to find the kernel for 8581 anymore on the website (google drive) and only see lsec6315 and not the 6316 for 8581.

Thanks!
[FYT Android Head Units] surfer63:
No, you definitely can't use it, although I do think that your unit will not even accept it as a flashable image.
[FYT Android Head Units] thugscorpion:
Thank you for your quick reply!

Is there any other way? I cannot seem to find anything and have no idea what sprd is.

Also, would it be possible to keep the screen and buy a FYT mainboard?
[FYT Android Head Units] surfer63:
Go to the Magisk website and read the documentation. Magisk is an almost universal rooting method and maybe your unit is supported.

I assume it will be possible to buy a FYT motherboard, but please check connections of the screen and how your motherboard is connected: that is screws or clamps on the same positions.
[FYT Android Head Units] Lakis_dj:
How can i skip the launch? ?
[FYT Android Head Units] gordgelin:

[FYT Android Head Units] nickrod93:
anyone able to tell me why i cant install marios launchers?
[FYT Android Head Units] j0hn83:
How are you getting to install them? You can't just install the .apk file while the unit is running.

You need to download the zip file from Mario's site, extract it to USB and flash it.
[FYT Android Head Units] nickrod93:
Yes, I did. I unzipped the file and added the insides to a clean USB and my unit says it has a firmware update and it goes through the whole process and I take the USB out when it says to but when it boots up the launcher isn't there or in the launcher list. after trying the correct way like that I have tried just to install the .apk file and it says this app not installed but it wont do it the correct way either.
[FYT Android Head Units] j0hn83:
Can you show me which launcher you are trying to download?

How many launchers are in the launcher list on your unit?

Is the launcher you are trying to download the same launcher number as you already have on your unit?

How to change the height of the status bar, I think 60dip is too big
[FYT Android Head Units] surfer63:
sys.lsec.status_bar_height=xy
[FYT Android Head Units] kazlaz:
Sorry, I don't really understand. Is it necessary to decompile systemui.apk?
[FYT Android Head Units] surfer63:
No, sorry. This is for the floating status bar at the bottom. If you are talking about the systemUI, you mean the notification bar at the top, not the status bar at the bottom.
[FYT Android Head Units] kazlaz:
It's the top status bar.
[FYT Android Head Units] surfer63:
There is no such thing as a top status bar. That is called the notification bar. Please use the correct wording to prevent confusion.

I am really sorry. You are right. The status bar is at the top. The notification bar is what you drag down from the statusbar.

Now I am causing the confusion :(

Coming back to the first answer:

Add the line "sys.lsec.status_bar_height=xy" to the config.txt of your firmware where xy is the value you want.

Add that config.txt and an lsec6315update to an empty USB-stick and flash it.
[FYT Android Head Units] kazlaz:
It's the one in the screenshot, do I need to decompile framework-res.apk if I want to change his height?
[FYT Android Head Units] newuzer1:
Any chance there is a similarly easy way to remove the time/date from the status bar? I assume not, @j0hn83 pointed out it'd require modification of the PeaceOS SystemUI.apk
[FYT Android Head Units] surfer63:
You do indeed have to modify the systemUI to removed/add "items" from the status bar.
[FYT Android Head Units] newuzer1:
Thanks for confirming. Unfortunately, that's over my head. Maybe one day I see if I can stumble through a decompile/compile/sign. Until then, I'm grateful there's much more knowledgeable folks sharing their hard work.

I bought a set of ambient LED light strips for a car interior, and it uses an Android or iPhone app to adjust the color hue. It works fine on my iPhone, but when I install the Android app on my Joying uis7862(s), the app is unable to make a Bluetooth connection. Is this because the FYT Bluetooth only allows inbound connections, so outbound connections will not work?

Has anyone found a brand of ambient LED which works ok over the JYT Bluetooth?
[FYT Android Head Units] surfer63:
Bluetooth is crippled on these systems. You can forget if it is not a phone, OBD or TPMS. Those are the only 3 BT deives that will work and only the approved OBD and TPMS ones.
[FYT Android Head Units] stoked:
I currently have a Dasaita max6 px6 HTCE in my highlander. Thinking of upgrading to a FYT unit, one thing that Dasaita really annoys me is that switching Bluetooth phones is not automatic and it will only auto connect to the previous phone. Do the FYT units auto switch Bluetooth connected phones? Also do they auto switch for CarPlay?

Oh thanks for that tip, so whow can one knows whezn system bring up from deep-sleep mode in our 7862 units ?,
[FYT Android Head Units] surfer63:
what? :unsure:
[FYT Android Head Units] mariodantas:
how can I know (via Android intent) when headunit wakes up from deep-sleep mode ?

I need to ckeck if a service is running when unit wakes up from deep sleep (ACC ON)
[FYT Android Head Units] surfer63:
You cannot.

There are two alternatives:

Do it like fytstarter: The ms.apk starts a number of hard-coded apps automatically on waking up, even though they no longer exist for many years already. That is what fytstarter does. It is an app with the package name of one of those old apps that are started but no longer exist.

Simply create an app that does what you want it to do without looking at the FYT unit intents. In Q19 I describe that the uis7862 FYTs allow you to specify which apps should be started coming from deep-sleep/cold boot. Simply add your app to that list and then do inside your automatically started app whatever you want to do from that app. This second option is even simpler. You don't have to write methods requiring specific authroizations that are no longer allowed (and you never get your app system-signed, allowing yout to start it from this acc on intent)
[FYT Android Head Units] mariodantas:
Thanks for that @surfer63 you're the best, really !
[FYT Android Head Units] Beauenheim:
Figured I'd let the Mekede 300s-600s owners know that the firmware was updated! The 6315_1.zip folder and the AllAppUpdate.bin are now updated 6/11/2022 and 6/13/2022 respectively. I grabbed it from Mekede's firmware download page.

I noticed this one had all the camera 360 stuff in the config.txt. I ended up erasing all that stuff and grabbing the config.txt from the previous update to revert all that, as it broke my aux capability initally. Still had to change the bluetooth to 0 to get it to work. What's cool is that carlink carplay/android auto app was updated May 2022. It seemed to fix the occasional failure to auto connect wirelessly to carplay.
[FYT Android Head Units] roti86:
Hi,

Is this the Mekede website you are referring to? If yes I can not download firmware as it is not possible to sign up to jianguoyun.com. :( If no could you please send me the link? Thank you.

[FYT Android Head Units] surfer63:
Did you test whether the launchers for SDK 27 work on our uis7862 units? Or did you not mean it like that and is it just to tell the user for which unit the launcher is?
[FYT Android Head Units] mariodantas:
You can believe me, all that launchers work in our units even if I really don't understand how is it possible !
