I installed some apps (then uninstalled) and now I have a strange behaviour of the screen, it scroll up and down (1 cm down) and seems to load something. I tried to stop some android processes and uncheck buttons of Nexi Voice App , but remain the upper left white dot point and nothing happens. I think to reflash the fully Mekede rom... Other solutions?

hello everyone, I installed the latest firmware (2022-10-27) distributed by JOYING official on the unit.
I haven't seen any particular improvements, but I noticed that the date of the baseband version has changed.
Does anyone know what this baseband version means?

The floating dot is touch assistant, you can go to the app and uncheck the options to turn it off.
Don't know but it seems significant enough that you can't rollback to the previous firmware.
Hi, I have a Chinese UIS7862 head unit with FYT=1. All is working well except that there is frequent restart whenever i start navigation using Google Maps. The head unit would go unresponsive up to a point the system restarts itself. Sometimes the system will restart randomly when I play Youtube videos.
At this point I do not know what is the actual root cause of this happening, but I keep getting the issues almost everytime i'm driving.
Does anyone have similar issues?

I had problem with my 7862 NOR FYT=1 , see my last post. I resolved the problem : I updated the mcu with latest MCU NOR_with 360 system 20220624_E60.rar , then flashed latest firmware (2022-10-27) distributed by JOYING official.
Hi all,
I was looking android headunits and found some are offered with 3 USB ports. Then I looked at the pinout for my HU and found out that connector E has two USB inputs. Could I just make a 6 pin connector with all the pins connected or do I need to activate the third USB port somewhere?
When I bought the Navifly M700S, it came to me with two wires to connect on the back. At the other end of one of the cables was a USB plug, while the other cable had two USB plugs. I think all these devices have these cables supplied. Indeed, I also received a cable to connect to the original USB port of my car (a Peugeot 308) but unfortunately I do not know where to connect the other end of the standard USB plug to the car located on the armrest.
Im not sure if my issue has anything to do with mcu. Anyway, my unit is without 360, maybe i can give it a shot to update the mcu. Where did you get the mcu update file from?
After some further reading. I found the mcu update file from 4pda site (MCU NOR_without 360 system 20211009).
I will try update the mcu and see if it fix the instability issue.
no probz for 360 camera I don't have it, try the mcu I suggested to you , it works (recommended on 4PDA)
Please do some googling both.
Baseband version updates are part of normal Android updates/patches. In this case FYT has obviously updated the underlying kernel with available patches from Android.
Baseband is the low level firmware for the "radio" which in this case is for (cellular) calling, WiFi, Bluetooth, texting. (so not the AM/FM radio).
Sorry for asking without searching. And thanks for the clear answer.
It seems that it was true that I felt that the 4G communication speed was improved from this update.
Another change point. The maximum volume control bar of 30 has been subdivided into 36.
Please can you point me to the firmware version? Of the 14 listed here, which is relevant for generic FYT units?
I can't decipher the Joying model numbers to know which to use unfortunately.
Many thanks

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.
