Thanks! Flashed it.
Now the whole procedure of setting everything up again after the automatic factory reset, really really cumbersome.
you cant, this chinese radio it is very bad for radio signal, signal it is strong only in town, i have isudar v72, not recomand to buy anything from isudar !
Thats not true. I have perfect reception. I even get Danish radio ststions and the border is 60km away from us.
If you have an active antenna you have to connect the blue cable.
Or in the settings on some head units you have to turn antenna power on.

YES PLEASE, YOU HAVE ISUDAR V72 ?
Your unit it is t10 not fyt, no ? t10 unit have strog radio signal, i talk with isudar
this cable for antenna+12v signal=0 !

Does anyone know how to control the sensitivity of the BT microphone? External microphone connected. Please how to find fiction step by step. Thank you
"Listen" to what @Clandaries says.
This has nothing to do with either FYT or another type of unit (MCD/E, Topways, whatever)
This has to do with having an active antenna or not.
If you have an active antenna, you need to connect the "blue wire". It is a blue wire on a FYT. If your unit is not a FYT, the color may be different.
Edit: The wire should be called "ANT power" or "Antenna Power" or something alike.

i tell, i dont have active antenna, it is car antenna, please see cable
what modele of antenna you have ?

Our posts crossed.
So, you purchased that 12V antenna amplifier in combination with one of those two wires in the image below?
Did Isudar told you to buy that? And then connect the red wire to the blue "Ant power" or "Ant cont"?
I really have no idea. I never used such an app. Did you contact the developer? [email protected]surfer63, i have app (tv app) why i cant use, i dont see video, it is problem from dev app ?

edit post, cable for car antenna without amplifier
i put only red cable from amplifier to 12v power to blue from radio,but signal increase ZERO, my radio signal work ok only in town after 15 km dissaster signal, with rns 510 signal it is more strong, this radio isudar v72 it is dissaster !

No idea about Isudar specifically, but my FYT 7862 (Mekede M500s) has a great reception. I would even say FM reception is slightly better than my original Kia stereo (made by LG I believe).
I use adapters to connect to my cars OEM aerials for FM & GPS and both work perfectly.
The FM aerial has no power connected from the radio.
Find the wiring diagram for your cars original radio and see if it has an ANTENNA POWER wire, or something named similar.
If it does have this wire then you need to connect that to ANT POWER/ANT CONT on your Isudar working and enable antenna power in the settings (Settings > Factory > Original Car Agreement > Antenna Power).
If it does not have this wire then do not connect anything to the antenna that has power as it can cause interference on passive aerials.
Hello all,
I have a Joying JY-FQS08N4G-B and a problem.
Resolution 1280x800
I wanted to change the key assignment and have installed the modded syu.ms.apk.
Now I have a black screen.
I have tried to install the update from Joying, but no success.
I can't confirm anything, the screen stays dark. Only the soft keys are illuminated.
Can you please help me.

Please read post #2 bullet IX "If everything goes wrong ...". I think the modded apk blocks everything and I think you really have to force your unit in recovery mode, being option 3), and try with that update.
It is indeed brand new and they also use a new kernel.
The kernel is from Mon May 15 09:14:56 CST 2023
The AllAppUpdate.bin is from 2023-05-19 08:47:34

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.33
config.txt overrules fyt.prop.
I also have my own config.txt with a lot of special settings, like indeed the default volume (to 8 in my case), but also quite some other fyt.prop values and other properties like "ro.build.go_lasttop=false" (as I don't want to start the last media player on reboot/wake-up).
And like I said: only a config.txt and a lsec6315update will do the job in case something weird has happened.
So you still don't need a custom rom, but please go ahead.3
no it is not possible, he just had NOR mcu from the start, that's why that other NOR mcu flashed without error
i have seen these devices with NOR mcu before -

This thread tries to be a "one fits all" thread about FYT based Spreadtrum Unisoc uis7862(s) (Unisoc ums512) and uis8581a (sc9863) 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 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.
- 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.
- Disable airconditions app on Tesla style uis7862/8581a units (see post #1780)
- Modded Launcher 34 (see thread "Modded Launcher 34 for uis7862(s) and uis8581a (and probably uis8514a)")

More about Firmware(s)
This post is valid for FYT uis7862(s) (ums512) and uis8581a (sc9863) units running Android 10 or fake Android 11 or 12.
Contents of a firmware zip:
Note that the firmwares for the uis7862 and the uis8581a only differ on the flashing binary and the kernel zip. Configuration files are the same. Some resellers deliver a firmware that contain two kernel zips and two flashing binaries, as the flashing binary will only work on the hardware it is intended for flashing the correct kernel zip.
- Kernel:
- 6315_1.zip: the kernel zip for the uis7862(s).
- 6316_1.zip: the kernel zip for the uis8581a.
- The 6315_1.zip or 6316_1.zip 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 for the uis7862 "should" be interchangeable between all 800x480, 1024x600 and 1280x720 models. The same for the 6316_1.zip for the uis8581a. Special resolutions come with specific lcdconfig.txt files.
- The binaries that do the flashing of the firmware:
- lsec6315update for the uis7862(s)
- lsec6316update for the uis8581a.
- These are the binaries that do the flashing of the firmware, optionally install a boot image or boot animation, optionally run scrips from the lsec_update folder after the flashing process itself has finished. These binaries can also be used to only flash a boot image, boot animation, or run scripts.
- AllAppUpdate.bin: Special zip 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 or use the scripts from post #3, bullet #4.
- config.txt: file comparible to the build.prop which can contain additional properties.
- 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. These are very limited cross-compatible. do not flash these if your do not know exactly what you are doing.
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. You see that we specify 0 from the rotation. This is because android is normally for portrait like screens. Our landscape models have a value ro.sf.swrotation=90 decrees as they are actually 90 degrees rotated. A Tesla style unit therefore is again 0 degrees and sometimes 180 degrees.
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=0
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
28-05-2023: I added two scripts in post #3 under bullet #4 to let you flash any AllAppUpdate.bin to your uis7862(s) or uis8581a unit.
II. AllAppUpdate.bin
III. The 6315_1.zip or 6316_1.zip
Again: the 6315_1.zip is the kernel for the uis7862. The 6316_1.zip is the kernel for the uis8581a.
(Inside also "III-a. More details about the files inside the 6315_1.zip/6316_1.zip and how to decompress and unpack/"open" them" and "III-b. Recompress uncompressed images from the 6315_1.zip/6316_1.zip to squashfs format for small (!) and easy access. (Not for flashing.)")
IV. Some info on partitions
V. The lsec_updatesh folder, lsec6315update/lsec6316update binary and 7862lsec.sh/8581lsec.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.
26Backup 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 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!
appBackup 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.
21Mods and Tweaks
==================================================================================
1. disable or (re-)enable the mediaplayer at startup/wakeup.
FYT mimics the behaviour of many builtin car units that it continues with the player or radio or BT connected phone player, that was active during "switch off". These 2 scripts can disable that behaviour (I want silence when I start my car) or enable it again (default FYT behaviour). This is a shameless copy of @gordgelin scripts with a slight modification where @gordgelin adds the command at the 16th line whereas most standard firmwares have max 8 lines or so. My script simply adds the line to 4th line of config.txt. Works on uis7862 (ums512), sc9863a (uis8581a) and sc9853i (could easily be ported to other FYT units as well).
==================================================================================
2. Script to correct the fytmanufacturer id in the fyt.prop
In case you get a big yellow bar with red letters in the top of screen saying "UI and MCU does not match", your fytmanufacturer id (ro.build.fytmanufacturer= XY) is incorrect.. (See also Q13/A in post 1 and section II. and vI. in post 2.
If you still know the original id, you can use this script to correct that entry again without completely reflashing your unit.
Read the README.txt carefully !!
You can download this script: ChangeFytmanufacturer
==================================================================================
3. Script to correct the screen orientation of your unit.
Probably you are here because you did not read the Forum well enough (especially "VIII. Flashing a Full firmware, an AllAppUpdate.bin or a new system/kernel/core from another reseller" in post #2 and flashed a firmware to your FYT with a different screen orientation.
What does this script do?
It can set the correct orientation for your screen. This is set by a property called "ro.sf.swrotation=xy", where xy is a value of 0, 90, 180 or 270 . Use the value from YOUR ORIGINAL firmware in the config.txt.
You will find a config.txt with this script that contains the default value for most units being ro.sf.swrotation=90
In case you have no longer your original firmware you simply need to experiment with the above values until you have the right one.
You can download this script: ro.sf.swrotation
==================================================================================
4. Two scripts to flash any FYT AllAppUpdate.bin to your unit.
EDIT: Some of the new Mekede M6Pro models and comparables from other resellers come with an lcdconfig for their 2000x1200 K screens. My scripts below do not take those files into account. I "think" that when you encounter an lcdconfig on the new downloaded firmware, you have to remove it and stick to the one installed on your unit.
What do these scripts do and how to use them
These scripts are for both the uis7862 (ums512) and for the UIS8581a (sc9863a).
The AllAppUpdate.bin, that contains the FYT application layer, is for both CPUs the same.
The scripts make a copy of your current config and use that to flash your unit using that config of your unit.
Some information to start with
FYT units do have an MCU and based on the type of manufacturer you can have a different MCU firmware. This MCU firmware is totally different from the normal downloadable firmware that you can get for your unit having new functionality, bugfixes, etcetera..
The Android layer is universal on FYTs but works slighly different for different MCUs.
How this Android layer should act on the underlaying MCU is determined by a property called ro.build.fytmanufacturer which can have several values.
A second and third property are the:
- sys.fyt.bluetooth_type property which is normally 0 or 1, but on the new M6Pro/M6Plus models anything up to 7
- ro.sf.swrotation. This property defines the screen orientation and is in 95% of the cases 90 (degrees), for Joyings often 270 and for Tesla screens (0 or 180).
Important
BEFORE YOU FLASH ANYTHING TO YOUR UNIT, YOU FIRST NEED TO RUN THE "PRE-FLASH" SCRIPT !!
Steps to perform
- Take a clean FAT32 formatted USB-stick (or a (micro-)SD-card in some USB reader/writer).
- Copy the contents inside the "pre-flash" folder onto the USB-stick (not the pre-flash folder with contents, but the contents inside the pre-flash folder).
- Insert it into your unit, let it reboot and go into recovery mode, and wait until the green message tells you that you can remove it again.
- Delete the "lsec_updatesh" folder including contents on your USB-stick !
- Make sure to keep the "myconfiguration" folder and check its contents: It must contain a config.txt and a fyt.prop. If correct: copy this myconfiguration also to a save place. You never know when you need a backup. If the folder does not contain those files or one of them, then don't continue but ask in the forum.
- Copy the AllAppUpdate.bin that you downloaded somewhere onto the USB-stick.
- Also flashing the 6315_1.zip or 6316_1.zip?
- UIS7862: If you want to flash the kernel as well, copy the 6315_1.zip onto the USB-stick.
- UIS8581a: If you want to flash the kernel as well, copy the 6316_1.zip onto the USB-stick.
- Now copy the contents of the "flash" folder onto the USB-stick.
- Check your "lsec_updatesh" folder. Do you now also have a "lsec_updatesh (1)" folder, or inside the "lsec_updatesh" folder something like a "7862 (1).sh"? It means that you did not delete the "lsec_updatesh" folder on the USB-stick, or that your file manager does not overwrite on copying. In this case: Redo step 4.
- Copy (not move) the config.txt inside the "myconfiguration" folder into the root of the USB-stick.
- You can now flash your unit using this USB-stick.
Remarks
- If you are thinking of using this in combination with @mariodantas' kernel, you need to know what you do. Mario's kernel comes with its own scripts and fmc app. Of course you can combine this if you know what you do, but do not simply copy everything on top of each other on this USB-stick. Please keep it separate.
- You can also combine it with PeaceOS, but also in this case @LLIyT_HuK's version comes with it's own scripts. So know what you do.
- The flashing script uses "twipe_data" in its "updatecfg.txt". This will clear your settings and all 3rd party apps which you downloaded from the Play Store or sideloaded from other locations. You can disable that by putting a # in front of the twipe_data line, but that is your own responsibility.
- Most newer firmwares nowadays come with an lsec script and a fyt_build.prop. This fyt_build.prop comes with a fake property to set Android to 11 or 12. I refuse to go with that absolutely incorrect and despicable behavior and I will not copy it.
- Once you have made your pre-flash copy of your config, you can also use the flash script to copy any modified fyt.prop or config.txt to your unit without using an AllAppUpdate.bin.
You can download both scripts in one zip: flash_any_AllAppUpdate.zip12
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.
