yes, I saw it, which is why I replied, but my FYT=1 unit doesn't show that option. maybe because I have a 1920x1200 unit and firmware? I don't know, but it's just not there. I guess YMMV here
You have to use the lsec6315update from your latest firmware. That binary has changed over time.
Replaced com.syu.settings but mic setting option did not come up so there must be something more
Mekede 500S - MCU: 2021.10.09 YIN_53_L6315_G23P48F64_E60_V:1.0
Kernel/System 2022.03.30

Maybe your kernel ?, 2022-03-30 ?, are you sure that you replaced the com.syu.settings correctly ?, did you see the colored icons in com.syu.settings ?, if yes then you replaced it, if not, the you didn't replace it !
In my case with firmware 2022-10-27 on two units FYT1 and FYT31 I have the mic option (internal or external)
i also have the internal external mic option after the update but its not working
Hi Mario.
How do I install this please?
Do I just need to include this apk plus the lsec updater on a USB drive?
Or does it require a script?

The mic option is there for me now on my Mekede M500s after updating com.syu.settings.
Thank you Mario.
Thank you Mario.
Just pointing out that this mod will not work without the supporting hardware.
Newer hardware revisions "M6 Pro" contain supporting hardware, this hardware provides a "switch " between external and internal.
Other differences are proper Fan control, instead of just being tied to the external amplifier on/off switch. (Source 4pda)

Right, so even if you see the switch in the settings it doesn't mean that the function will work as expected !
please share the script.
The com.syu.settings.apk you posted earlier is different from the one that came in my allupdate package from joying. Even though datestamp on joying is newer.

Thank you for the awesome work! I have a quick question, I used the auto generate backup zip feature and then there was a download popped up at the end. I didn’t find any option that I could use to download the zip. Is there any way I can download it directly to the HU (didn’t see my HU nor USB stick as an option), or do you have any suggestions how to download it? Thank you!

Use the documents (or another app) to go to your storage folder, inside you will se a folder named FMC_data
You stand correct, script l used failed to replace com.syu.settings. So just went for a full update with latest version from Mekede site and now mic select option is there. You guys are doing a awesome job, thanks !!
Sorry for the stupid question, but I'm a newbie. @mariodantas, it takes a script, what does it mean? Please can you give me a step by step to install this file. I apologize again for the newbie question. Thank you

Updating the MCU does not fix issues with missing canbus functions.
It would need either.... Selecting a different vehicle make/model, updating the canbus, or using a different canbus completely.
Updating the MCU is more likely to break something than it is to add missing canbus features.2
This looks like a 7731 unit but I am not sure whether it is a FYT unit. Looking at the systemUI it is a FYT.
Why do you need a splitscreen launcher? And what do you exactly mean with that?
The splitscreen functionality is offered by Android, not by the launcher.
To enable it you have to tap the "double rectangle" in the top right (and note that the notification bar in the top is part of the SystemUI.apk, never of the launcher).
In the next screen you then first tap the "opened book" icon to select the app you want on the left side, and then (already in the right half of the screen as after the first selection, that app is already in the left half of the screen), you select the second app to be displayed on the right.
Note that you can swipe left-right through the apps to select one, in case you have a lot of apps open.
Edit: I saw that this "how to enable splitscreen" is not mentioned in some Q&A, so I made a Q24 in the Q&A section in post #1 referring to this post.22
Yes, it is. You do need to read post #1 and #2 though to get the necesary background info.
What do you mean with the "sellers factory passcode"? Do you mean the manufacturer id (ro.build.fytmanufacturer)?
That is what you need.
You als need the properties ro.sf.swrotation (only different for Joying units and Tesla styler units) and sys.fyt.bluetooth_type (occasionaly differsbetween units). post #2 section VIII.
With those values you can flash any FYT firmware with a minor tweak.
You can also use my hwgetinfo.apk (seee my signature) or my getinfo script (post #1 at the bottom).
But post #1 and #2 is a "must read". -

This thread is supposed to become a "one fits all" thread about FYT based Spreadtrum uis7862 (Unisoc ums512) head units and its software, modded or not. The first few posts will be "collection" posts for all kind of info but will also link to other useful information that might be added later or in other threads.
Part of the tips, mods, etcetera are also valid for FYT based sc9853i and sc9863a (uis8581) head units, and even for the older PX5 and Sofia-3GR.
DISCLAIMER: Every action you do on your unit is on your own responsibility. I will help where I can (and probably a lot of other users as well), but I am never responsible.
This thread is meant for:
- Discussing firmwares (see post #2), modded firmwares, mods and rooting (not advised).
- Tips, tricks, mods to improve the general usability of your unit.
- Try to solve design errors/flaws where we expect that these Chinese resellers/suppliers will not do it.
- buyers advice (is this one better than that one?)
- 4G providers, DAB+ modules or DAB+ software (see here for DAB-Z by @realzoulou), Navradio+ (see NavRadio+ ported to UIS7862-FYT devices by @KoTiX2 , sub-woofers, OEM cameras, OBD devices, TPMS or other peripheral devices.
- ABSOLUTELY NOT for posts about "what is/are your favorite app(s)?"
- Questions about repairs, warranty and the like. That is between you and the reseller. Questions about interchangeabilty of hardware are OK.
General unit information
Q&A - Questions & Answers
FYT Settings explained
Mods, useful software, tweaks for your system, etcetera.
Some will be added later
- Backup the firmware of your unit (see post #4). Useful if you do not have a firmware yet for your unit.
- Disable or (re-)enable the mediaplayer at startup/wakeup (bullet #2).
- Change Fytmanufacturer script to correct the fytmanufacturer id after a flash with another resellers AllAppUpdate.bin bullet #3).
- DocumentsUI for Android 10. Without it you can't write to an external USB drive with other file managers. That is because the documentsUI is missing. Install it, open it once and afterwards your file managers can use it to get access.
- Android Shortcut Settings: This program by Mario Dantas gives you access to some hidden settings in the (FYT) head units.
- Mario Dantas (@mariodantas ) created/build the website "uis7862 FYT Factory":
- A great and very extensive collection of launchers for FYT models and also a collection of (un)rooted kernels for your unit. (Read post #2 section III "The 6315_1.zip" for more info on kernels and how universal they are.)
- He now also created a new firmware (MD-edition) that after flashing gives you some very handy and essentials options for on-the-fly rooting and root access for selected apps, starting apps from boot, make firmware backups, save your /data/data partition, etc.
- @seb21 made a modded combination of the com_syu_ms.apk and a Config.apk. This combi allows you to change the "hard-coded" steering wheel buttons in case you have/use a CANbus and add "no kill" functionality. See Modded syu.ms.apk.
- getinfo script. This is in fact an extension of my HWGetInfo.apk, but as an lsec script. It gives more info than the HWGetInfo.apk as it runs as a flashable script thereby having full access to the system.

More about Firmware(s)
This post is valid for FYT uis7862 (ums512) units running Android 10 or fake Android 11.
Contents of a firmware zip:
- 6315_1.zip: The zip file contains all "standard" Android software, drivers and apks. It also contains the the boot.img; the system/vendor/oem partitions and a few other things. This 6315_1.zip "should" be interchangeable between all 800x480, 1024x600 and 1280x720 models. I don't know for the special resolutions, Tesla like units or rotable units. Probably they are by now also compatible.
- AllAppUpdate.bin: Special file that contains all FYT apps (This can be (un)packed with any (un)zipper, but I prefer 7-zip). This file also contains special files with reseller specific configs. This one is only interchangeable between the same reseller-id, unless you change that reseller-id.
- config.txt: file comparible to the build.prop which can contain additional properties.
- lsec6315update: The binary that really does the update
- oem: (OPTIONAL, DEPRECATED) Folder containing some additional apps. These are not automatically installed, but can be found in folder OEM in your internal memory (internal SC card called USB). Do not confuse this with the oem partition where the AllAppUpdate.bin will be installed to. I use this folder upon flashing to add some of my preferred apps that I want to have available, but not directly installed. Note: Nowadays the preferred location for these kind of apps is in the vital-app folder inside the AllAppUpdate.bin.
- updatecfg.txt: Contains instructions for the flashing process
- Stm32ud.bin: (OPTIONAL) binary to flash the MCU
- GD32_E230_64K_Flash.Hex: (OPTIONAL) the hex file that contains the MCU firmware itself.
I. (Factory) Firmwares
Some commands that can be put inside updatecfg.txt
Code:twipe_all # Wipe entire system twipe_data # Will wipe data partition (but not /sdcard, internal memory). Wiping the /data partition will wipe all config, all 3rd party apps and updates of system apps. This is the same as a "reset to factory defaults" twipe_cache # Will wipe the cache of the apps thereby removing the temporary files that are stored for those programs. twipe_sd # Will wipe internal memory /sdcard (but not the data partition) dellapp # Remove all 3rd party apps make_updates # Make an upgrade U-disk boot file test # test unit and firmware before flash
Some properties that can be put inside config.txt. Say you live in Brazil and you want your locale settings immediately on Brazil, you can add that. As a second example we take a "Tesla style" unit which is actually a rotated horizontal unit:
Or you want to improve the microphone function a little, you can add or modify the following lines:Code:ro.product.locale = pt_BR ro.sf.swrotation = 90
If you decide to download a 4pda Russian modded firmware, make sure you remove the settings from this config.txt file that makes this a Russian firmware (unless you are Russian, but in that case you probably would not be here).Code:persist.sys.zlink.mic.vol=9.9 persist.audio.mic.senstivity=1 persist.btmic.gain=10 persist.btspk.gain=7
II. AllAppUpdate.bin
III. The 6315_1.zip
(Inside also "III-a. More details about the files inside the 6315_1.zip and how to decompress and unpack/"open" them" and "III-b. Recompress uncompressed images from the 6315_1.zip to squashfs format for small (!) and easy access. (Not for flashing.)")
IV. Some info on partitions
V. The lsec_updatesh folder, lsec6315update binary and 7862lsec.sh script (and what about "universal" scripts)
VI. Compatibilty between uis7862 (ums512) Firmwares
VII. FYT firmware types over the different CPU configurations
VIII. Flashing a Full firmware, an AllAppUpdate.bin or a new system/kernel/core from another reseller
IX. If everything goes wrong and your unit ends up in a boot loop or doesn't get past the boot logo.
18Backup the application data of your uis78672 (ums512) unit (or your sc9863a (uis8581a) unit).
This is especially useful if you do not have an official firmware from your supplier yet. The kernel/cores are universal on these FYT uis7862/uis8581a units, but the AppUpdate is not.
This works on both the uis7862 and the uis8581a. I don't have this ui8581a unit but it is actually the same for these two types of FYT units.
It does not backup the 360 camera setup/config!
It will actually also make a backup of your sc9853i unit, but there it requires some extra follow up steps. Next to that: There are already many firmwares that can simply be downloaded.
This script will create a directly flashable backup!
Backup script
- Unzip the contents of this zip onto a clean usb-stick.
- Insert it into your unit and let it reboot.
- It will make a backup of the specific firmware part into folder BACKUP onto the USB-stick (which should therefore have >1GB free space).
- When it is done, you will have four (4) files in this BACKUP folder: AllAppUpdate.bin, config.txt, lsec6315update or lsec6316update, and updatecfg.txt
- If you copy these four files to a clean usb-disk and also copy an 6315_1.zip (for uis7862) or a 6316_1.zip (for a uis8581), you can always restore your unit to its factory settings.
Restore option I:
For a uis7862: Copy the AllAppUpdate.bin, config.txt, lsec6315update, updatecfg.txt from the BACKUP folder onto a clean USB-stick. Insert that one in your unit and let it flash your unit.
For a uis8581: Copy the AllAppUpdate.bin, config.txt, lsec6316update, updatecfg.txt from the BACKUP folder onto a clean USB-stick. Insert that one in your unit and let it flash your unit.
Restore option II:
In case option I still gives you an unstable system, you need to do a complete flash. For that you also need to flash a new kernel/core.
- Download the universal kernel/core for uis7862 (current version: 07 December 2021). (For uis8581 download yourself)
- Unzip it to the same USB-stick which you used in "option I". This means that this content will be added to the USB-stick. It will not replace the content.
- Insert that one in your unit and let it flash your unit.

Hi.
Maybe i have solution for you.
I have modded the ms.apk to add some extra functionality. One of the extras is to modify Canbus based Steering Wheel Controls. The mod is two part : modded ms.apk and settings app.
All info is in explanation.txt file.
You must replace your syu.ms.apk with this modded apk. Mod Config App.apk is normally installed as every apk.
