It depends where in the world you are.

Many of these units only support some specific 4G bands and they simply don't support many of the bands used by certain carriers in some countries.

They support very few 4G frequencies used in North America.

Driving around much of North America you'll find yourself connected to a cell tower that supports 4G then when you get out of range of that tower you may find that the next tower uses a 4G band that isn't supported by your head unit.

For most of these units the supported 4G bands are

Check which bands your carrier uses and see if some or all of them are supported.

Some brands like some of the Atoto's support more bands used in North America than the Mekedes and Teyes units.

I find WiFi Tethering from my phone to give the best connectivity. Your average smartphone supports considerably more bands than these head units.
[FYT Android Head Units] mcnaugha:
Thanks but I’m in the UK and this is my hometown and journey to work. I know I get 4G in these areas hence the recognition that the unit is only checking signal strength every 10-15 minutes I think. I have installed one of those signal monitoring apps that allows me to see the signal strength and where it drops out. Unfortunately, where I park my car for the night, it’s shielded by old sandstone buildings and this really cripples the signal. So, it starts out on some level of 3G but i can drive fairly quickly into strong 4G signal areas but the unit doesn’t realise this for too long. If I’m in a 4G area long enough, sure enough, it switches up to 4G and I get amazing download speeds.

In built-up areas in the UK, every major provider has a presence on the cell towers. So, all frequencies covered.

I’ve worked in high-end IT for 25 years now and one of my current duties is managing around 4,500 cellular-enabled Android devices. So, I know a little bit more than average.

i was hoping there’s a parameter somewhere that’s setting this signal strength optimisation. I can see it reacting to a low 4G signal and switching down to HSPA+ but it’s so bad at switching back up in areas where I’ve had great 4G before. If I reboot the unit, of course, it goes straight to 4G in these areas. Clearly handsets have tuning for this which is far more agile.
[FYT Android Head Units] j0hn83:
Then I've no idea. The provided 4G aerial on these units isn't very good, particularly if it's hidden behind a dash. That varies car by car though.

I used my unit for about a month with a prepay o2 SIM and didn't get the issue you describe. It stuck to 4G pretty well though the signal strength wasn't great and the speeds achieved were much lower than with the same network on my phone.

I'll check mine tonight but I'm sure it reverted back to 4G pretty quick on the few occasions it dropped down.

First and foremost I thank all the contributors and senior members on the forum for providing so much useful and important details for the FYT units. Based on post#1 I was able to successfully download and install a launcher form mariodantas site. But the challenge I am currently facing is that on the home screen in the widget which is suppose to display google maps. It is coming up blank.

Will appreciate any help / pointers on the subject.

have you looked in the factory/engineering settings which is accessible via MD's Settings Shortcuts app?
[FYT Android Head Units] Ahto Simakuutio:
I have M500S on Citroën, but with the difference that I have the car original Type C display as well. I would be very surprised if fiddling with those above mentioned FYT settings would make the headunit to configure the car DRL setup as well 😲

Need to keep an eye on if that should ever happen. I have the same preference of how the lights should work, i.e. DRL's during daytime and automatically switching to dipped headlights at the dusk.
[FYT Android Head Units] desibawaji:
Thank you for the pointer but that did not resolve the issue. After installing the app got the same results. The app on the top left corner was showing google maps icon with a warning stating "All apps not supported".

@surfer63 / senior members, SOS - please help. I have a uis8581a unit and everything was working fine. I had initially taken a backup as explained in post#4. After which I installed PeaceOS and wanted revert back to the original AllAppUpdate.bin. I copied all 4 backup files and explained and tried to restore. Now my unit is stuck in bootanimation and after sometimes gives an error "command not found".

Any help will be highly appreciated .
[FYT Android Head Units] desibawaji:
Yes, Tried and did not work
[FYT Android Head Units] desibawaji:
HI, Please note that I was able to recover from the issue after going through the instruction provided by @surfer63 in post#2. But the challenge I am facing is if update my original backup as instructed it is still stuck on boot. But if update with PeaceOS then it is working fine.

What I want to do is revert back to my original factory apps. I have followed all the steps and copied the config.txt to the USB also. I dont know if the backup created has copied all the required files or some were missed. My Backup folder had 4 files as mentioned.

Please provide your expertise in resolving the issue.

Thanks
[FYT Android Head Units] louforgiveno:
Could be wrong, but shouldn't you be adding your 6316_1.zip to USB thumbdrive?

Your factory apps should be contained in that zip if i understand right
[FYT Android Head Units] desibawaji:
Thank you but as per post#4 I am using Restore option I which needs only 4 files. As per my understanding 6316_1.zip contains the kernel and I have already updated that with @mariodantas MD Edition. Only thing I can think of is that the backup was taken prior to the kernel update to MD Edition. Hope that is not causing any issues or mismatch after load.
[FYT Android Head Units] louforgiveno:
Appears i was wrong, just checked the size of the allupdate file and it appears to be big enough to contain the factory apps.

By chance did your fyt manufacturer code get changed....sorry still new/figuring this all out myself.

Maybe check your backup content vs after the kernel flash
[FYT Android Head Units] TPMunster:
I was trying to overcome the missing functionality of reconnecting to whatever phone was available from the paired list using Macrodroid (similar to Tasker). I installed it on the head unit, hoping to use the BT action of connecting to a specific device - but the device list is completely blank. I guess that is because the phone BT connection is a separate individual setup deferring from BT in general - correct?

Do you, @dishe2, or @surfer63 know of any other service call or a way to engage with that phone BT connection?

Thanks in advance
[FYT Android Head Units] LLIyT_HuK:
Worth checking the files. Sometimes the backup is created with errors.

Also, when changing allappupdate, you need to use the updatecfg file with "twipe_all"
[FYT Android Head Units] dishe2:
Yeah, the Bluetooth system for receiving audio from a phone is not supported by AOSP and is therefore not using the standard Android Bluetooth stack. On my unit it appears to be a separate Bluetooth receiver hardware (they can actually "see" each other which is odd) which is controlled by an app, the app is the bluetooth UI on the head unit.

That's why it won't show up with any app that is looking for the standard Bluetooth paired devices. Those are looking for the standard stack and this is something else.
[FYT Android Head Units] desibawaji:
Thank you, You are correct when I extracted the archive using 7zip it gave one error on a *launcher22. But even after reconstruction that zip without the file it still does not succeed. Anyway now I don't have an original backup of my unit so does not make any sense in pursing that subject. The only allappupdate.bin which works now is PeaceOS. Also after installation of the PeaceOS and updating / resetting FrontApp I still cannot get google maps in the widgets on main screen.

Can some tell me which launchers are compatible with PeaceOS which can have configurable widgets on the home screen.

Hey guys. I recently got the 12.3" for accord 8 FIY UIS7862(S), QP1A, 8/128gb.

Studied this and other forum a lot. And still have questions I can't find answers to. Could anyone please help?

I upgraded the firmware to MD EDITION (by @mariodantas ).

Installed 2 upgrade bundles from his website.

Now I have a few issues and questions:

1. When I set up time manually, it resets to July 7, 2:32 am. How do I keep the time up to date?

2. Map app boots automatically at startup and shows full screen. How to disable it? I set all settings to off. Tho Map is set as a launcher app.

Launcher 06 (com.android.launcher6)

3. How do I make Home, splitscreen and back arrow icons white? they are red now. (after upgrade 1 from @mariodantas

4. Wallpaper is reset after reboot. How to fix it? Picture is located in manually created Pictures folder.

5. Where to download the 06 launcher black/gray design update?
[FYT Android Head Units] mariodantas:
Bundles have apps for 1280x720, should work in your resolution but not fit entirely in the screen, auto map should be disabled in settings as well as setting launcher6 (06) as default.

I guess that you have a copy of your allappupdate.bin
[FYT Android Head Units] mariodantas:
I'll stop publishing bundles
[FYT Android Head Units] sk8xnick:
Settings wont help for maps.

Dont stop posting bundles, add a bit more info on what units/screens they fit for and etc. :giggle:
[FYT Android Head Units] sk8xnick:
Guys are there any instructions how to re install firmware. I want to remove everything and install from the ground up.

Story:

1. Updated firmware to MD-Edition (http://fytfactory.mariodantas.com/fmc-platform/)

2. Installed 2 bundles from @mariodantas (https://drive.google.com/drive/folders/1nIWvOicjAEctuBC_nvk90shNKC2u1_y8)

3. Reset all data to factory settings (User - Backups & Reset - Erase all data)

After that new menu design appeared.

BUT

1. I still cannot change the launcher theme to black

2. deafult navi app setup wont launch

3. cant change red icons

Thats why I want to reinstall everything.

But when I plug in the usb drive with MD-EDITION firmware, nothing happens.. idk how to clean everything and do it the right way from the beginning.

When I do the backup that I created before MD-ed upgrade, It gives me 2 red lines and nothing happens after the process.

Please help.
[FYT Android Head Units] Fltlander:
Do you mean ground up by starting with the original firmware or with Marios firmware?
[FYT Android Head Units] Fltlander:
Did you try to reset the unit with the push pin reset? If not, try that first then try below.

Even thou you aren't bricked this can help you...#1 Thing is to get a fresh firmware from your reseller or manufacturer for your model!!!!

From surfer63 post #IX. If everything goes wrong and your unit ends up in a boot loop or doesn't get past the boot logo.

- Download a fresh firmware from your reseller.

- Unzip it to an SD-card/USB-stick (as normal)

1) Simple solution: Put the USB-stick/SD-card in your unit and wait till it reboots and starts the flashing.

2) More complex softbrick:

Put the USB-stick/SD-card in your unit

"push" the Reset (RST) with a paperclip or something like that.

When the boot logo appears, reset the unit again. Now the flashing process should start.

3) Most complex softbrick:

Put the USB-stick/SD-card in your unit

"push" the Reset (RST) with a paperclip or something like that.

When the boot logo appears, reset the unit again. Now the flashing process should start.

Sometimes you need to reset up to 3x times.

If after 3 times resetting the flashing still doesn't start, your recovery partition is damaged.

Also make a "updateconfig.txt" file with "twipe_all" in it and put it on the root of the sd or flash drive with the firmware when you reflash.

If I have anything wrong please correct me as I'm just a bored guy sitting around flashing and reflashing until I make up my mind what the hell I'm doing......
[FYT Android Head Units] j0hn83:
Almost perfect.

It's not a config.txt containing twipe_all but instead it's updatecfg.txt containing "twipe_all".

The config.txt file needs to be the same as what you backed up originally.
[FYT Android Head Units] louforgiveno:
Yes, don't stop (unless you have reasons i don't see).

You're doing great service to us all.

[FYT Android Head Units] Fltlander:
I would write Atoto support and ask them that.

I would get a hold of Atoto support and ask them. Their support is pretty good for being in China. They respond on a timely matter.

Be prepared to

send them a clear picture of the current system version of the car radio for further confirmation. You can locate the system version of the car radio by going to settings > system >about device> MCU version [quickly tap this option 4 times in succession], and scroll down to the bottom when the pop-up window appears.

Heres an example pic...

Meanwhile. Managed to install this software 爱影第三代UI_新马自达-7862国外收音机可选全景360-1920x720-不分屏-默认外置蓝牙_22-12.zip

Then installed 190000025_yl25_com.android.launcher6

Then installed MD upgrade Mariodantas 2023-06-09__FYT7862_FW_MD_EDITION_WITH_MAINSERVICE

and then installed his update 2023-06-09__FMC_UPDATE

Now everything works as supposed to, BUT... Got a message UI and MCU does not match.

As I found out this happened because I installed Joying firmware on FYI. But it works great! Now how do I remove that warning?

AND how do I change the theme to black? Where is this setting in MFC?

Hi All,

Is any of you aware of a tool that helps to put the currently played song details from carlink app to the launcher?

For radio I'm using Navradio+ which shows the radio details on the Car launcher pro main screen, but when i play a music through apple carplay, it does not appear there.

Also not sure if there is any way to change which RDS lines are shared through canbus with the car. My car's screen shows the frequency but i would prefer station name if available.

Thank you

Hello!

I want to add an app to skipkillapp.prop list.

Which script should I use?

My android head is not rooted
[FYT Android Head Units] LielBachar:
I did It too and got the same problem

any clue on how to fix it without flashing new firmware?
[FYT Android Head Units] marjanoos:
Is it possible that newer units like M6 Pro have working AF? I’m using NavRadio+ with MD kernel and I swear frequencies were changing between itself automatically.
[FYT Android Head Units] sk8xnick:
Yes bro, I managed to solve almost all issues. Thanks that i know russian language and downloaded firmware from their resources.

Why the hell this forum does not have database for all the firmwares in one place?! or I never found it.

Note I have front and back cam, no 360. Both worked after the flush.

So do my steps:

Every step was done with previously erased USB flash drive.

1. Download and and extracted this firmware to usb flash drive: https://cloud.mail.ru/public/2HUg/ZUfhXcQVD/firmware/заводские/FYT_31/iying_ui_-7862-360-1920x720-_22-12_2023-01-06_0849 (very slow speed cuz servers are in russia)

Plugged in the flash drive, pressed reset, saw android logo, pressed reset again, saw logo, pressed again, saw logo pressed again and now waited for the installation.

2. Installed MD EDITION http://fytfactory.mariodantas.com/fmc-platform/

3. Installed FMC UPDATE (my Gdrive) https://drive.google.com/drive/folders/11Q636TAsLSvJ35PcoXtxVvySNLxbw3P3?usp=sharing

4. Changed FYT manyfacturer id to 116 (on my Gdrive) - extracted file, followed instructions, changed 999 to 116, saved and uploaded on empty flash drive.

4. Installed 25 and 29 launchers (on my Gdrive) (use 25 but love 29 too lol, but 25 has Gnavigation window on desktop which i need every time)

5. Uninstalled 22 and 5 launchers (on my Gdrive) (that helped to get rid of after reboot bugs)

After these steps I ain't got no any bugs after load nor during usage. Strongly suggest to download everything I have on my Gdrive cuz I could delete the folder any other sunny day cuz will need space.

2 issues remain:

1. Wallpapers cancel after relaunch

2. Time cancels after relaunch until I connect to wifi.

[FYT Android Head Units] SerFeda:
Hello everyone,

I've installed the 7862s (M700s) on my Audi TT 8J, with front and rear cameras.

Everything was working fine and as expected (switching to rear camera when inserting the reverse gear etc...) after few hours the unit started going on and off continuosly, until now that is always off but it turns on when I insert the reverse and I can see the video but nothing else...

I tried to unplug all the wirings but the unit will stay off unless I put the reverse gear.

Can anyone help me figuring out what is going on?

I wanted to download the firmware update but I can't signup to the website because of an error (403 on the website).

Could someone send me a link to the firmware update?

Thank you
[FYT Android Head Units] j0hn83:
Just a FYI, it isn't a 7862S inside the M700s.

The M700S contains the older UIS7862 and not the newer UIS7862S.

The newer S variant of the 7862 SoC has a higher clocked CPU (2.0 GHz vs 1.8GHz) and a number of other improvements to other components on the motherboard.

Edit: seems I'm wrong and Mekede now ship the M400-700S range with the improved SoC

As for your issue, it sounds like the Android OS isn't even booting up. The reverse view happens outside of the Android operating system.

i would attempt to reflash the correct firmware. If that failed I would reach out to your seller for support.
[FYT Android Head Units] SerFeda:
On device info it says:

CPU: UIS7862(S) Octa-Core 2.0GHz@8.0 GB(Memory) + 128 GB(Storage)

isn't it the updated version?
[FYT Android Head Units] j0hn83:
Yes it might be, they might have multiple variants of the M700S, which is rather silly.

I can't find any listings from Mekede themselves for an M700S with a 7862S SoC.

Mekede renamed all the newer device as the "M6 Pro".

The M700S with the newer SoC becomes the M6 Pro 8Gb+128Gb, with a 2k screen it's a M6 Pro Plus 8gb+128Gb.

Edit: clarified by Matt below. Is indeed an M700S with just the newer SoC but none of the other features of the M6 Pro range.

I guess they ran out of the older 7862 SoC's or the price difference is minimal to Mekede.
[FYT Android Head Units] Matt Devo:
Mekede has been shipping all the Mx00 units with the 7862S for some time now; the rest of the unit's specs are unchanged
[FYT Android Head Units] cbd dvd:
Received a Mekede M700s and the same, thing here, shows UIS7862(S) 2.0GHz.

The box (perfectly packed) show that this is a M700s with 2K screen.

So, is this the same as M6 Pro Plus?
[FYT Android Head Units] j0hn83:
So just the updated SoC? Same older case and older motherboard? No mic port etc?

Interesting.

It appears not. Just the newer SoC. None of the other new features that come with the M6 Pro (dedicated mic port, upgraded Bluetooth chip, bigger capacitor, etc).
[FYT Android Head Units] cbd dvd:
Yes, not other features but it's something to have the newer soc. Also, I receibed the M700s with the box of M6 Pro Plus.

Very good package (like a normal phone) sealed.

Very good quality materials

Smooth system and apps.

Great!
[FYT Android Head Units] Matt Devo:

[FYT Android Head Units] Matt Devo:
what CANBUS box did your reseller include with the unit?
[FYT Android Head Units] SerFeda:
RZ-AUDI01

But when I press on my car model (AUDI TT 2008-2013) it doesn't save the setting, like nothing happened.

Moreover, when I turn the car on it goes to the rear view even if the rear camera wiring is not connected, then I press the RST button and it boot normally to the default launcher.
[FYT Android Head Units] Matt Devo:
sounds to me like that CANBUS box is incorrectly putting +12v on the reverse signal line at startup. Can you remove that wire from the CANBUS plug and see if the problem persists?

I've been using RAISE boxes without issue on MK2 TT's and B6/B7 A4/S4/RS4's for some time now, though I always set them to OD/Audi/A4/OD in the factory settings since it provides more info that way on the system info app. Never seen a case where it wouldn't save a change.

go to Settings/System/Device Info and tap the 'System info' line to open a pop-up box. Take a pic and post it here.
