We all say that the kernels are identical on all FYT models and as such all kernels can indeed run on all Mx00 or M6 models or non-Mekede FYT models (apart from annoying Teyes).

However, when I created the latest modded kernels based on the 5 December M6Pro3D kernel using my preconfigured partition templates, I got an error when flashing it. The vendor partition grew from 358MB to 379MB for the M6Pro3D compared to the latest (September kernel) of the normal 7862. And that 358MB size has been stable for more than a year.

The vendor partition contains all non-AOSP firmware necessary to support the SOC and other hardware (simply said).

So I guess the vendor partition on the M6Pro3D contains extra drivers/libs for the new Qualcomm BT chip and maybe for other stuff as well. (But I good be wrong as AOSP supports many BT chips. I didn't take the time to make a deep analysis).

Next to that: (older) Mx00 kernels run perfectly fine on the M6Pro, but limit it to 1.8GHz, just like a normal 7862. So somewhere some tweak in the M6Pro3D kernel also makes the 7862S run at 2.0MHz. (And does the Mx00 kernel use the Qualcom 5.1 BT chip correctly?)

But as said: the latest modded kernel I made was based on the M6Pro3D kernel of 5 December and it runs without any problem on my M500S as I simply think they are completely backwards compatible with the normal 7862. That is what FYT always does. Leave in the old and just add something new.

Good morning everyone, I have a fyt uis8581a car radio and I have an ELM327 obd2 as shown in the photo, but searching with Bluetooth doesn't find it on the car radio, and for example when I start the torque app it doesn't recognize anything. I did scans but nothing, so I assume that this car radio is not compatible with this OBD2. I wanted to know which OBD2 I could buy to have compatibility with this car radio.
[FYT Android Head Units] j0hn83:
Just a FYI...

Those blue OBD2 dongles are the very cheapest versions available. They have caused issues with the ECU on quite a few vehicles I've tried them with if connected while driving.

After about a minutes driving it completely kills my traction AND stability control module on my Kia Sportage until I remove the dongle and restart the ignition.

Very dangerous indeed.

Running an ELM Validator app on it shows very poor results (I'll post them this afternoon).

Edit: To add, they have never damaged anything. I ran mine for about 4 years and have connected it to a few cars for friends and family. It even helped clear a couple faults.

I was then warned about them by a mechanic friend.

I've intended for some time to create a thread dedicated to discussing compatible accessories for our FYT units (USB DVR's, TPMS, OBD2, DAB+ adapters, parking sensors, etc) with reviews of hardware and links to compatible apps etc.

I'll do that this evening and link it to this post.

This thread isn't really the place for accessories.
[FYT Android Head Units] tommysf8787:
Ook thanks ☺️
[FYT Android Head Units] ptuchik:
Found new option for config.txt which does the same as

adb shell wm overscan

it is

sys.lsec.overscan_rect = 0 0 0 0

if anyone needs it.

P. S. Only don't know how to set the offset color, for example Black
[FYT Android Head Units] gordgelin:
this option was added not long ago specially for 2k screens where car frame overlaps screen, so you can adjust A BIT. so obviously there is no option for color. also if you set invalid values it may lead to problems with apps
[FYT Android Head Units] ptuchik:
Yeah, mine is overlapped for 5 px on the bottom and right, but not by the car frame, but by screen’s black border itself
[FYT Android Head Units] ptuchik:
Does anyone know how to make the Bluetooth contacts show First Name then Last Name and a space between them? It now shows Last Name then First Name and there is no space between and looks ugly, no matter how the phone is configured.

P. S. And also there are 8 blank contacts after each sync, not sure what is it )
[FYT Android Head Units] gordgelin:
that is "normal" for 720p screens. almost any screen has this
[FYT Android Head Units] tommysf8787:
Good afternoon, did you then create the post for compatible accessories for our fyt car radios?
[FYT Android Head Units] ptuchik:
Anyone?
[FYT Android Head Units] ptuchik:
Can anyone share T'eyes CC3 latest AllAppUpdates.bin or at least their latest BT apk?
[FYT Android Head Units] gedster314:
Curious about the two sim slots. Is using the sim slot on the back not suggested for use? On the Etiy tear down video the guy mentions Etiy suggests not using it. I use a TMobile unlimited tablet plan in the wired sim slot. I have a free 250 min/month phone and text sim that I was thinking of putting in as just as a back up calling sim if I don't have my phone and Google Voice has one of its occasional bad days.

Also, does using the headunit as a hotspot work? Is would is there a way to change the TTL value so that it kind of masks that I am hotspoting. TMobile in the US looks at the TTLvalue of your packets. On routers people mangle the packets with an entry in the IP tables. Would be nice to have the option but it's not a big deal for me now since my tablet plan has 10GB of hotspot data and I really don't need hotspoting in the car.
[FYT Android Head Units] gedster314:
Answered the question about the sim port on the head unit. Went to insert the sim and missed the port and the sim fell into the head unit. Had to open up the headunit...what no sim! The sim has slid into where the LCD panel is. Had to pull it all apart to get the sim out. Back together and everything is fine.

Be extra, extra careful when trying to use that sim port.
[FYT Android Head Units] anginx:
hello @surfer63, is there any plan to support custom firmware for uis7870? I know it’s too recent but being FYT should be pretty straightforward, I assume.
[FYT Android Head Units] surfer63:
No, there are no plans. And it is not straightforward at all. FYT complicated things a lot for "modders".

Every firmware has a different password and probably requires its own lsec binary with the same compiled-in and embedded password.

Scripting has changed. They still used scripts, but the scripts are now binary compiled to an lsecsh1.bin file.

So far I have no idea how it is compiled. I tried SHC and unSHC, but they are clearly different. I tried hexeditors to see if I could reverse engineer what they did. I tried base64 and uuencode/uudecode methods, but so far nothing. Parsing it through "file checkers" to see what is in it or search for know headers, was not successful either so far.

Please find such a compiled lsec script attached. I currently don't even know what is "inside" it.

If anyone can find out what it is: please let me know (@gordgelin: do you have a clue?)

I am also ready to ask on 4pda as there are also quite some tech guys/girls who might be able to crack it.

Edit: I removed the script. I was warned that it contains public keys so that FYT can see who shared them.
[FYT Android Head Units] gordgelin:
the thing is that (at least for now) you will not be able to create working script in lsecsh.bin format even if you know how it is encoded. it is signed and you do not have the key
[FYT Android Head Units] tommysf8787:
Good evening, while walking around I saw this photo of a ts18 which has the uis8581a as cpu and the PowerVR GE8322 as gpu, exactly like my Fyt car radio which however has another firmware, as you can see from the photo. I wanted to know if by any chance it is possible to install this ts18 firmware on my Fyt car radio. Mine is a 7 inch 1024x600.
[FYT Android Head Units] marchnz:
No, because TS is not FYT.
[FYT Android Head Units] surfer63:
I now realize that this is actually really confusing. The same scripts are in the Android 12 firmware and beginning to be rolled out on tens of thousands of car units. So if users use it, they all share to FYT? That is strange and if so: FYT shares the firmware with their buyers ands you can only update your unit by using the the firmware with that accompanying script.

Is there a flaw in my reasoning?
[FYT Android Head Units] haf7:
hi,

im currently using mekede m700s 7" with built in 360 camera. On the firmware download page, which category of firmware should i download for firmware update?

theres no "7862 7" with 360"

only have 7862 7" 8"

and

7862 9" 10" 360 camera
[FYT Android Head Units] Cavalier Condorelli:
Hi @surfer63 I have an "annoying" Teyes unit. Do you think if I will uninstall Toppal voice app then Google assistant will start working? Currently I have both installed, I can run Google assistant manually. but if I tried to make a call it stated it cannot, only Toppal voice has access to the dialer.

Second. If I want to rollback and reinstall the Toppal voice in case that trick didn’t work, how to do it, where can I find the apk and get it to register again?
[FYT Android Head Units] j0hn83:
Google assistant doesn't work with the Bluetooth dialer on any FYT unit that I'm aware of.

I think it might work with a SIM in the head unit and using the Google phone app, but that is unable to receive calls.

Removing Toppal just means Google Assistant would be the default voice assistant.
[FYT Android Head Units] Cavalier Condorelli:
Thank you for your answer. What I discovered is that Google Contacts is able to make call using the Bluetooth dialer... So why not Google assistant is a mystery.
[FYT Android Head Units] saady002000:
hello my freind, @surfer63

i have vertical uis 7862s fixed on land cruiser prado car, i bought from Navifly stores.

with your support, recentrly i have fixed the issue of 360 camera system but still i have issue with UI that i cannot modify car model, it shows me Maserati car and contcted the seller he told long press on the car photo but when i tried it changes backgroud photo only not car widget.

i think i will face the same issue with 360 software also, because i did set car model there yet.

kindy advise please

1- how to chnge car model?

2- is it possible to change widgets?

3- how to safely install new UIs without affecting MCU and applications?

4- can i use 7862 vertical screen file from MEKEDE site as MCU as attached in screen shot photo

thanks again
[FYT Android Head Units] j0hn83:
Surfer63 does not have a vertical unit, or the 360 system.

You should point questions to the general community and not tag a specific member like that.

I can't help with 1 and 2 as I also have neither vertical screen or 360 system.

Points 3 and 4 stop worrying. Don't touch the MCU.

You cannot affect the MCU by installing UI's.

If you don't upload MCU firmware, the MCU doesn't change.

The vertical firmware you have shown does not contain MCU firmware.
[FYT Android Head Units] saady002000:
I am sorry if i mentioned specific member.

I did not know that it is kind of disrespect or against community's rules.

Thank you for the advice.

But still i have to search more, How can I change car model photo in my screen.

Kindly explain to me in details if you got any solution.

I am not expert.

Also, My car has 3 UIs interface I do not know also from where I can safely download and install more.
[FYT Android Head Units] j0hn83:
It's not against the forum rules.

It's fine to tag a specific member to say thank you or if they are already helping you to provide support.

It's just best to direct questions to everyone.

I don't know. I think the car model on your screen only shows on vertical units. I do not have this so I don't know how to change the car.

There was a good site for more launchers provided by a helpful member here called Mario but his site is currently offline.
[FYT Android Head Units] surfer63:
@john83 already gave you some answers.

1. First show us a listing of your /oem/app folder. In the Vertical units they add extra programs to fill the bottom half of the screen. The aircondition app is a well-known one (for which I wrote an enable/disable script), but that car "thing" is not known to me.

2. It is not possible to change widgets as such. You can modify the launcher to some degree, but in this you also need to modifiy how the screen is built up and which programs are used. There is no expertise here.
[FYT Android Head Units] saady002000:
Hi all

I added here photos for listing applications came with the unit.

But I remmember that inside applications bin folder I have seen suborder named carmaker or something like that which contains apk file inside tomorrow I will send you photo of that folder from my computer.

Right now I have added available photos of unit.

System data and applications installed.

Note: 360camera added to that applications today only.
[FYT Android Head Units] saady002000:
Last Update

hello everyone

@j0hn83 @surfer63

as i told you in previouse reply i have checked allapp update folder and found folder named carmark and inside it apk file named 190001100_com.syu.carmark

i attached it, and i added my config.txt file as well

can you check if possible to update config.text file to read carmark?
[FYT Android Head Units] surfer63:
The carmark apk is an "old" one. It lets you decide the car brand for the splash-screen at boot.

Maybe the new carmark contains more, but it is very hard to check if your rar is completely empy.

And your config.txt has absolutely nothing to do with it.

Is there an app or method that can kill the app I want in sleep mode?
[FYT Android Head Units] marjanoos:
Has anyone using iPhone experienced fact, that phone won't reconnect using Bluetooth?

I have M6 Pro with 3D fw. And my phone is 13 Pro with 17.1.2 iOS. Wasn't able to reproduce that though.

Also if connected, I have to set manually during phonecall that I want sound through HU instead of phone speaker. When I tried that with other bluetooth speaker, voice is automatically set to BT device.
[FYT Android Head Units] t08jfl1:
I keep getting this error when using the "appBackup-V1.2 script" as well as just a kernel upgrade so different apps but same error.

Has anyone else had it ?
[FYT Android Head Units] surfer63:
All apps are killed when going in sleep mode. What do you have in mind?
[FYT Android Head Units] surfer63:
Using the same USB-stick? Your usb-stick is corrupt.

Run a checkdisk and/or freshly format it.

Hi guys,

Not sure if this has aleeady been addresses, but after flashing some config.txr from here to improve mic, i’ve lost my unit’s ability to run on 4g network. Nomatter where I I am, it only shows H+ not 4g. Does anyone care ro help and share config txt with lte modem lines?

Thank you in advance.
[FYT Android Head Units] j0hn83:
I've never seen such a line in config.txt

Did you just flash a random config.txt? Did you backup your current config.txt? What make/model is your device?
[FYT Android Head Units] binary_boy01:
Sorry for wasting your time. Problem fixed, with a simple top up to my sim card. Seems like when my bonus internet is consumed, nav displays H+ in status bar. Checked today and all works fine.

As for config.txt, I got it from thread, not sure from which post, but is ok, tested this as well. Once again, cheers.

I have a ums512 head unit running on android 10.

I have no idea what the model or manufacturer is but I am sure it's not one of the bigger brands like joying.

I've tried using multiple sim cards on my unit ( theres this sim card reader on a USB like cable) but none are detected by the unit.

When I go to sim settings, there are 2 slots with am imei number.

Should I attempt a firmware update to resolve this or could this be down to a faulty cable?

[FYT Android Head Units] InElement:
I've been having some wireless Android Auto connectivity problems with my unit (EKIY KK6, UIS 7862S) lately, and I'm not even sure how to begin debugging. Basically, half the time I start the car (whether the unit boots from sleep or a cold start) the CarPlay/AA app will just hang at the "Connecting..." stage and go no further. It just sits there, with the phone and unit having recognized each other but refusing to finish connecting.

The only fix seems to be rebooting my phone (a Samsung Galaxy S23) at which point the unit will jump into AA right away, with zero issues.

Little help? Has anyone encountered this sort of thing before?
[FYT Android Head Units] surfer63:
first question: yes. second question: no

Hey, I tried to flash a Mekede firmware on my 7862s and everything worked, except for the yellow banner. Then I modified the fytmanufacturer to the one my unit came with (31) and now the default launcher doesn't load (just a background flicker, like it tries to start and crashes) and only one of the 4 launchers it comes with works.

Any ideas?

Having a bit of an issue configuring an APN. When I go to edit a line in the APN, I can not see the text to edit in the popup window. It's probably a font or DPI issue. Is there a better way to edit an apn? Can I edit a text file and put it somewhere in the system or is there an easy way fix it so that the text shows up in the pop up window when editing an APN line?

The disable script runs

This will overwrite line 4 in /oem/app/config.txt.

Hello!

Unfortunately, I haven't ordered it yet. The steering control functions work on what the manufacturer gave (RZ-15). The various factory menus, e.g. the clock setting, daytime running lights, etc. are not, however. I am thinking of getting XP, but there is no guarantee that it will work well either. It also depends on the firmware version. Our fellow forum member Specy01 has such an adapter, ask him, he also recommended it to me. He has experience. You might want to think about whether these features are really necessary. If you don't use it much, you might be spending money unnecessarily.
[FYT Android Head Units] surfer63:
You are right. It should be

sed "4 a ro.build.go_lasttop=false" /oem/app/config.txt

I corrected the script.

Thanks for pointing this out.
[FYT Android Head Units] surfer63:
Flashing / firmwares updates can be found on Youtube from the manufacturers.

tips etc. can be found on several sites: Look under post #1 FYT settings explained from the Joying and Teyes manuals and videos.

For mods there is nothing unless you read my kernel thread, but that is very high-level and no videos.
[FYT Android Head Units] newuzer1:
From what I gather, this is a workaround for Android 10 similar to this.

Anyone able to confirm they are able to use this in newer releases without issues?
[FYT Android Head Units] j0hn83:
Just thought I would update this with me findings. This previous test was on my Mekede M500s.

Trying to stream any high quality video on the M500s over 2.4GHz was impossible.

Due to the head unit not supporting 5GHz channel 149 (which many mobile phones default to) I would have to take additional steps to connect with 5GHz which would need done each and every time I got in the car.

Today I tried streaming some 4k video on my Mekede M6 Pro over 2.4GHz hotspot and to my surprise it played flawlessly.

So I ran a speed test the exact same as on the M500s and was very happy with the improvement.

TL;DR

The M6 Pro is considerably quicker over 2.4GHz than the M500s
[FYT Android Head Units] surfer63:
You have a 7862 FYT. Both your app layer and system layer are pretty old.

Use my HWGetInfo apk from my signature to get more info on manufacturer id and bluetooth version.

And then start reading post 1-2 before asking further questions about upgrades and firmwares as that is already explained there.
[FYT Android Head Units] blackwrx02:
I'm unsure if this is the proper place to ask, but given it would likely need a modded launcher, I'm hoping so.

I'm have an EKIY T7 and like the radio widget function on the stock launcher, but would like to have a larger nav window widget. I frequently use radio and nav together and would like to be able to easily change the radio station. Currently I'm running nav app full screen and have to swap between nav and radio apps to change stations. Is there a launcher mod where I can use the standard EKIY radio widget but have a larger nav widget? Or something else besides the stock widgets that would accomplish this?

I tried running radio and nav split screen but the stock radio app doesn't work well in split screen because it doesn't show the preset buttons to change stations, only the seek arrows.

Thanks

Why does a TV application work on the phone with image and if I install it in the car does not work with video image?

Can I do something about this? Does anyone know if the APK can be modified to be seen to be installed in a phone.

...

I tried to install APK, but I tried from the browser, no chance of having a video image, I talked to the developer, Google prohibits the video image, the youtube works.
[FYT Android Head Units] honda2015:
I'm not sure if that's the right place to ask but I can't connect via Bluetooth BLE to my generic brand less Elko LED light strip using the Lotus Lantern app (alternative apps won't pair to the device either). I can however easily pair on my Pixel phone.

Using a Bluetooth scanner app I can detect and even pair with the device but not in the Lotus Lantern app in the Android head unit.

My head unit is a Mekede mk6pro fyt uis7862s with unrooted plain vanilla system.

I almost assume that the Chinese sellers block some BLE devices from getting paired but then it's strange that the Bluetooth scanner on the head unit can see the device.
[FYT Android Head Units] surfer63:
Yes, they block most Bleutooth devices.

No, it is not strange that you can see them. A unit first needs to scan whatever BT device to see it. How else would it know it is even there? So they also have to do a full scan.

And then they block everything apart from what they think is allowed.

This has been described at least 250 times in this forum. Search first.
[FYT Android Head Units] honda2015:
Thanks. I was actually somewhat aware of that. It is just a pain in the neck that the sellers castrate full-fledged systems to half-baken stuff. I guess asking Mekede to do something about it won't help at all.
[FYT Android Head Units] j0hn83:
Have you tried changing the Bluetooth type in config.txt from 7 to 0?

The Qualcomm chip (7) might not connect to BLE devices but the Soc (0) should.
