[FYT Android Head Units] KlaverBoer:
Hello everyone. Did any of you guys installed the 10-27-2022 update? If so. What is new? I have checked the file size, it is 1,4GB.
[FYT Android Head Units] marchnz:
What did you find after installing it? Anything new or bug fix?
[FYT Android Head Units] KlaverBoer:
I didn't install that version. My unit is working fine with the my current version. I was just curious if somebody else did an upgrade and if its worth to upgrade.
[FYT Android Head Units] surfer63:
Multiple people did. What they mentioned is that wireless Android Auto worked better.

I only flashed the kernel as new security patches and the new baseband firmware was included in the kernel.
[FYT Android Head Units] Petarkco:
As well as being able to choose between the front and "back" (external) microphone.
[FYT Android Head Units] kommando:
I have the Mekede version with that additional setting but I tested it with a mic test app and it showed if you select rear mic then the front mic is still connected. So at least on mine the setting does nothing and my guess is there is a hardware change needed for it to work and the hardware change is on the new Pro versions only.
[FYT Android Head Units] surfer63:
Like mentioned: This does not work with the older Mekedes/NaviFlys/Joyings/Teyes/ etc. If you have one of the new M6 Pros (Mekede) it works as it has been enabled hardware wise. Same for the new Joyings and T'eyes.
[FYT Android Head Units] Harlley Sathler:
Hi, surfer63. Good to know! Is there any news about upgrading to new firmware without losing all the user data?
[FYT Android Head Units] surfer63:
Technically that is very simple to do in the flash. But it can lead to unforeseen issues.

All those firmwares come with a file updatecfg.txt. In that file you will find a line "twipe_all" or "twipe_data". Simply remove or disble that line and nothing will happen. The first line is almost always "test". Leave that one in as it checks your unit and your fimeware.

When an Android app changes the way it saves its configuration leading to conflicts, that app must take care of it itself during its upgrade. FYT apps don't do that.

If you are lucky everything works as it should. If you are in bad luck, you might run into weird issues or even an unstable system.

So it is up to you to take the risk.

Now if you run into such weird issues or even an unstable system, you can clean your USB-stick you use for flashing.

Then only copy the lsec6315update binary onto it AND add an update.cfg to it only containing

test
twipe_data

In that case all data, settings and installed 3rd party apps will be removed. Mostly this will be sufficient but will require a lot of reconfiguration.

If even this does not deliver a stable system there is no other option than completely flashing your system.

Of course: if you only flash the kernel you will not receive the new FYT apps, but you will not loose anything either.
[FYT Android Head Units] Harlley Sathler:
Thank you very much for your reply. I think it's worth trying. All in all if things go wrong and I need to completely flash the system, this is exactly what I need to do to update it.

Has anyone been able to ADB into the Joying w/ either a USB cable or via wi-fi?

I have the cable attached to the OTG labeled insert on the back of the Joying.

I plug the cable into my computer and it does not see the Joying.

I went into developer mode and changed usb to file sharing. Nothing changed.

I searched for usb networking debug to try to adb via wi-fi but it seems joying has hidden this ability.
[FYT Android Head Units] Moldeb:
Use https://xdaforums.com/t/android-settings-shortcuts.4336131/ to go to original Android settings. Haven't tried ADB though but should work.
[FYT Android Head Units] CCJ22:
Thank you, that worked

Hi everyone new to the forum, hoping someone can help me but I doubt it because I have messed up big time.

I have a joying uis7862 4gb 64gb android 10 unit, the touch screen became unresponsive so I purchased a second had unit with a working screen but faulty unit. I flashed a new screen resolution as mentioned in post #462

But now I have a black screen, the unit lights up but I can't see nothing or do anything. I have tried reverting back to original firmware with no luck, hooked unit up to a pc with usb but the pc is not picking it up, I also tried the USB out to hdmi with no luck either. Is there anyway I could get it working again?any help will be much appreciated please?

Thank you
[FYT Android Head Units] teeter477:
Can anybody summarize the latest state of rooting this device with the latest Joying firmware? I'm a total boomer with searching posts on here, I can't find a recent mention. Can somebody point me at the latest rooted firmware? Or, if it's possible to use some sort of universal root with the latest firmware, that would be awesome too.

The only reason I need root is to be able to resize my screen to fit small bezels in my car. If that's achievable without root, that would be awesome to hear about too!

Thank you!

Forgive me, I get turned around with kernel vs firmware. This is an all in one solution? With a unit straight from the factory, all I need to do is flash MD Edition?

Finally, ca you point me toward instructions for how to flash a 7862 FYT unit?
[FYT Android Head Units] TPMunster:
Hi everyone

Just got a new Joying head unit and wanted to root the device to be able to modify the hardware buttons.

Couldn't figure out the module number so contacted Joying who tells me the device number is not listed on their website but shares software with model UQS07N4G-B. Downloaded the newest firmware dated 2022-10-27.

I tried the Magisk rooting option two times with two different USBs but got an update error each time.

Any advise?

RTFF, there's info for the learning. I'm new isn't an excuse
[FYT Android Head Units] hksaaa:
my android started to smoke today, and when i disassemble ive seen that my capacitor started to burn but radio was still working fine, and on capacitor it only says KM 105c, if someone can help me and tell me witch capacitor i should buy to fix radio, there is alot of KM capacitors on ebay but diffrent capacitance value, diffrent max votlage etc... ,i would be really thankfull
[FYT Android Head Units] mclellan83:
Figure I might as well try here, can't figure out how to get my lower unit to have the control bar at the bottom like it is on the top unit. The top unit doesn't need it but for some reason has it, anyone know how to get it back?
[FYT Android Head Units] thechemist13:
I'm looking to get a new VW specific head unit and I live in the USA, does it matter if I have it ship from the USA warehouse or the Chinese warehouse?
[FYT Android Head Units] mclellan83:
It isn't VW specific but with the launchers you can make it look that way, doesn't matter just the amount of time it takes to get to you. Joying is usually pretty quick either way but should be faster with US warehouse
[FYT Android Head Units] thechemist13:
Does anyone know how much max amperage the amp turn on wire outputs?
[FYT Android Head Units] toecheese:
Ugh. Somehow managed to plug in my screen upside-down and now the screen no longer works. Radio still plays and I can change stations with the dash controls. But when I plug in the screen (correctly) it only flickers with a brief, slightly brighter shade of black, but no visible display. I tried unplugging the car battery for an hour, and also resetting the radio with the reset button.

Seems like I fried something. Anyone else have experience with this boneheaded move?
[FYT Android Head Units] Bandeiri:
Hi Guys,

Sorry if this is not the right place to post this message but I'm looking for some support as I am thinking to buy a joying unit based on the UIS7862. The seller in aliexpress sent me the MCU version of the radio : JY 53 C63L N32P48F64 V1.0 Can you tell me if this is a good platform ? is the FYT ?

​
[FYT Android Head Units] surfer63:
Yes, it is FYT and Joying is one of the better resellers. See the PM as well where you asked. Next time do not double post.
[FYT Android Head Units] pwood999:
@surfer63 do you know if the screen ribbon cable uses the same pinout as the older Intel Sofia head units ?

The reason I ask, is my install has a 7" screen mounted in the dash, and 100cm cable to the head unit under passenger seat. There was & is no room for the HU behind the screen in my car.

Also I don't like the latest Joying 7" with the rotary volume knob, so hoping I can upgrade using my existing screen.
[FYT Android Head Units] surfer63:
It depends. It can still be the same interface, or not.

Some years ago they all had an lvds interface, nowadays most come with a mipi interface. But there is also the edp and HDMI.

Joying had some time where they mentioned for their firmwares for "the old interfaces" and firmware for the new mipi interfaces.

And these interfaces are NOT compatible when it comes to sending the several signals to the panel (Google for it and read multiple articles as not all articles are correct)

I really think your Sofia3GR is NOT compatible with a new interface for a new screen.

But to be honest: I have not looked at cable differences yet. Maybe not even all wires are usedm, but that I don't know either. I will also google myself for that.

But have a look at your system info and compare them.
[FYT Android Head Units] pwood999:
Thanks, will check the system info later today.
[FYT Android Head Units] Wadsofat:
I had the same problem and used a Panasonic EEUHD1E103 capacitor as replacement. It has been running perfectly for the past 2 months since replacing it.
[FYT Android Head Units] techy101:
If this is the unit then yes, it's the new one. Android 10 is not available, to my knowledge, on the old Intel boards. Also, the CPU cores are in fact listed on that linked product page. The older Intel units show the CPU model in the "More Information" page.
[FYT Android Head Units] packyman:
does this unit still have the touch beep tone on, after coldboot/reset?

on the old Android 8.0 FYT PX5 4GB/64GB units it have set it to on self after a reset, although it was deactivated before.

someone tested it for root ?
[FYT Android Head Units] techy101:
I haven't had this issue with either my 8.1 unit or this new one, even after completely removing power. It has always remembered to keep the touch beep turned off.
[FYT Android Head Units] hal752:
I was wondering if someone could help. I came across a insignia / regal version from IYING. Are they the same?

https://a.aliexpress.com/_BOziv9
[FYT Android Head Units] stefcio007:
Just picked up one of these units to replace an ageing Klyde PX3 (1GB RAM), 1024x600 TFT screen.

First impressions. Quick. No interface lag and switching between apps.

Screen is much better, I went for the QLED 1280x720 (did not confirm with tool).

I used the Carlinkit Wireless CarPlay box with it, it's not compatible with the stock Android Auto/CarPlay app, I think that app only works with the cars wired version.

I had to install the AutoKit apk for wireless CarPlay to work.

There is a "surround" sound feature in the amp settings and it does make the music sound better. There are coax and digital out for audio.

You can't connect to bluetooth devices that are called OBD, but I did manage to get Torque installed.

WiFi is very fast now being 5GHz and an actual antenna installed.

Looking forward to modding this. Plan on installing iGO for navigation as it comes with no Navigation app.
[FYT Android Head Units] techy101:
This is a time alignment function; the "surround" name makes no sense IMO. They show the units as cm but they are actually milliseconds. Each of those dials delays the specific speakers so the sound reaches you at the same time. The default settings are pretty good in my car, but if you want to really dial it in you can measure the distance to your head and calculate the correct delay (for standard altitude, temperature, humidity, etc...)

Yeah, sadly they still have this locked down hard.
[FYT Android Head Units] stefcio007:
I can't get AutoKit to remember right side driving position, always set to left, hopefully it's a bug that can be patched with the in-app updater.

iGO installed but wants to read data from "GPS card", hopefully I can either copy the files to its working folder or get it to read the data off a USB drive.

I connected the fan today and boy, it's loud, I disconnected it. Haven't had overheating issues yet, if I do then I'll probably replace it with a quieter fan.

My canbus adapter has no beeper so there's no audible beep from the parking sensors, I do have a camera at least but a bit annoying.

Still seeing if I can unlock the bluetooth, need to get this in the hands of more experienced people but shouldn't be long as it seems to share similarities with the SC9853i units.

Going to try and load some stock apps from another manufacturer that I extracted from an OS image uploaded to 4pda, maybe they're less restrictive or at least have a nicer UI.
[FYT Android Head Units] TommyToad:
Anyone else have problems with the device generating touch events by itself? I have problems when i have the CarKit app open, it "clicks" all over the screen (beeping constantly and does stuff in the android auto-apps).
[FYT Android Head Units] stefcio007:
Is it normal to not be able to install updated apps over the stock apps simply by installing the APK? I'm assuming they are locked because they are running.

Might try installing the Joying OS at some point but don't want to brick. Had success on older units with the putting KD on KGL and Hal9k mod.
[FYT Android Head Units] techy101:
Yes, I'm talking with Joying about it right now. Can you get video of this? What is the weather like where you are? Is it cold or low humidity? (I swear this is a relevant line of questioning)
[FYT Android Head Units] stefcio007:
I seem to have soft-bricked my unit. Seems the recovery procedure is a little different on these. Downloading the OS from support and will re-flash.
[FYT Android Head Units] TommyToad:
Yes, it was about 6 degrees celsius and it got better as the temperature increased. But one instance i had the car in the garage (16-17 degrees) and it still did it when i booted it up...

I'll try and get the videos up asap!
[FYT Android Head Units] techy101:
I hate to say it, but that's good to hear. That's the exact same behavior I have noticed and this tells me it's not just my unit. I know Joying is able to access videos on YouTube so that's a safe place to upload.
[FYT Android Head Units] surfer63:
There is no recovery mode on these units.

Ther recovery partition only does one thing: After 3 unsuccessful boots it tries to load firmware.
[FYT Android Head Units] gamer765:
Would you be able to share the OS update file once you have it?
[FYT Android Head Units] stefcio007:
Re-flashing failed a few times even with the factory supplied files. Later I was supplied with some small files (less than 500kb) and that brought the screen to life.

It seems you can flash any OS but these few config files are specific to the unit as the OS they supplied me is different to the one it came with. The OS seems to be a Joying image.

I can confirm that you can pair to bluetooth adapters called OBD so maybe Joying isn't locked as they claim?

It actually shows a linking prompt now. It will "pair" but not "link" successfully in the custom BT manager but when you go to Torque it will show as a paired device you can choose.

It also appears apps can write to their own folder now, before I had trouble. It will come up with an Android system prompt that allows apps to update themselves.

I think I'll enjoy it for now until the community gets tweaking more.
[FYT Android Head Units] gamer765:
[MENTION=2238164]stefcio007[/MENTION], Would be great if you can provide these files. Especially said small config files. I'm trying to figure out how these systems work. It appears that some manufacturers, Teyes in particular, have a third layer of DRM. They have zipped assets/resources with an .ogg extension that is encrypted at the file level and it is believed that the keys to assist in decrypting are stored on the unit. Maybe these config files you were given could hold an answer.
[FYT Android Head Units] JRANGER615:
i finally got my unit and it looks solid all together. I havent did any testing with it yet though
[FYT Android Head Units] stefcio007:
XDA uploader fails for me because "a security token was missing".

The files are:

6315lcdconfig.cfg

config.txt

logo.bmp

lsec6315update

config.txt contents as follows:

For example, during update my screen is in portrait view but physically it is in landscape, after updating it becomes landscape so seems this file is important.

There might be other lines we can add here to change settings, seems trivial when you look at it, someone more experienced could write?

FYI, every image comes with these files of varying configuration.
[FYT Android Head Units] stefcio007:
If you flash an OS image that contains MCU information that doesn't match your MCU it will give you a banner at the top of the screen stating it.

Looks like I can flash different images as long as the config files for my unit are there.
[FYT Android Head Units] stefcio007:
If I have my ACC off the unit emits a loud pop from the speakers randomly but a few times a minute, anyone else have the issue? Not sure if it's my unit or the car as the car gauges move randomly when this sound happens.

If I turn ACC on then this does not happen but not ideal if you just want to sit in the car for a bit.
[FYT Android Head Units] Dhunt84:
Anyone having Wi-Fi issues? I get horrible reception. 1 or 2 mb download speed on average. I have onstar Wi-Fi in the car and it's averaging 20mb dowloads. When I switch to mobile data from my phone I'm averaging 17 mb download. What gives?
[FYT Android Head Units] cleaa:
My only explanation for this is you have 2.4Ghz wifi connection active and bluetooth on. Try disabling bt and check speed.
[FYT Android Head Units] techy101:
Agreed, the 2.4GHz band is still pretty slow. The new 5GHz band is much better and one of the big improvements. Does your phone support 5GHz hotspot?
[FYT Android Head Units] Caryt4:
I just installed mine in my Motor-home and so far all is working as expected.

I do have a couple of questions, hope this would be the proper place to ask.

I have a 64gb thumb drive with tunes from my I cloud.

This plays perfect in both my Audi's and my Jeep JK factory systems.

But plunged into the USB ports of the Joying if just says no files?

Second question, my MH has 3 camera's that go to a switcher that I'd like to also see on the Joying. Its a std RCA plug. Can I plug into the backup port or need to use the Video input?

Thanks, I'm 66 and not a Tech wizard so this is all new to me..
[FYT Android Head Units] Dhunt84:
It's not the Bluetooth. I turned it off all day yesterday and drove around and still had crappy wifi. My phone does support 5ghz hotspot. Would you happen to know how to change it from 2.4 ghz to 5ghz on the joying head unit or is it automatic? I can't seem to find anything that will allow me to make a change.
[FYT Android Head Units] techy101:
The head unit will join whatever hotspot you tell it to, 2.4GHz or 5GHz. Just make sure that your phone is forced to the 5GHz band.
[FYT Android Head Units] Dhunt84:
thanks.. I tried it this morning and it works. speeds are definitely better. I drove in a storm for about 14 miles this morning and streamed a movie the entire way.
[FYT Android Head Units] r.onic:
Hello!

any news as for your Bestycar delivery? Did they shippet it with a boat? ;)
[FYT Android Head Units] techy101:
Joying sent me a pair of files to try loading in to fix the cold weather touchscreen problem. They said to just put them on a flash drive, put it into the unit, and it should automatically import them. However nothing happens when I use either of the USB ports or when I reboot with the drive in either of the ports. The head unit recognizes the flash drive but I just don't see any file import, message, etc... happen. I should note that I'm using the USB extension cables, but I'm not sure why that would have anything to do with it. Would I not see anything happen even if it was importing the files?
[FYT Android Head Units] surfer63:
The UB extension cables are just fine. I only use these.

And yes: you should see something happening. If the unit flashes software you will see scrolling messages over the screen. A bit like in this video (after 30 secs)

Which files did they send to you?
[FYT Android Head Units] techy101:
They sent me a .dat file that looks to be what's supposed to execute the update and a .bin file that updates the touchscreen parameters somehow. I'm not allowed to share them here though :(
[FYT Android Head Units] surfer63:
No problem.

In that case I would just ask them.

[FYT Android Head Units] steakikan:
I will try to install it tomorrow, but for some point I might not be able to tell

-My car doesn't have Canbus connection, I will try the SWC see if it works.

-DSP not sure how to find out except if you open the unit. At best I could only compare it to my AVT head unit but I might be able to capture some sound sample from the Optical out.

-HDMI sound, I might need some tools to capture HDMI, I will see if I could capture the sound from Elgato but that might not be so sure too

-Radio RDS, I don't think my country have RDS station but I will try to scan some
[FYT Android Head Units] techy101:
If you have the surround control/time alignment then you have the DSP
