so anyone rooted on the latest update.. Does it still cut off sound to google maps and assistant?

And also anyone know how to solve the issue with the steering wheel button not being able to completely mapped out . Only the back, forward, pause, and volumes are working in the new update.

hi

is there a way to decompile / mod Stm32ud.bin ?
[FYT Android Head Units] IG_Vasilich:
No. Not possible.

Even if it would be possible, i don't think you could do anything with C code for one specific microcontroller, as many things are control of specific hardware.
[FYT Android Head Units] mclaudio:
thanks

my question is because i cannot program SWC. they work but cannot assign different functions, altough there are some keys that are not assigned, but if i use the "Protocol print" option, i see the radio is receiving data from this buttons...

how can i assigned them?

thanks

GPS fault

Hi! I have a 6,2 inch 1 DIN unit with 4 Gbyte Ram and 4G. Until today the unit works flawlessly, but now the GPS don't find current position, the GPS signal disappeared on the fly. I restart the navigation software (I'm using Waze), but nothing happened. I checked the K index, today's value is only 2. What could have happened? I tried another application (Google Maps), but it also couldn't find the GPS receiver.
[FYT Android Head Units] surfer63:
Broken GPS cable or the connector is no longer firmly connected to your unit. It might have loosened due to vibrations.
[FYT Android Head Units] feket663:
Thanks for help! Luckily I have some coax cable with SMA connector, Tomorrow I will try it.
[FYT Android Head Units] surfer63:
I actually meant to first try to tighten the connector on the back side of the unit.
[FYT Android Head Units] feket663:
Today I reinstalled Waze, and the GPS works flawlessly more than 1 hour. I don't understand it...

Edit: Certainly I checked the GPS connector, it was firmly attached.

regarding the "obd" string check..can't we just remove the string checking then?
[FYT Android Head Units] mjd1975:
Not important
[FYT Android Head Units] ojuniour:
Nevermind...I figured it out.. There is no point in having the Bluetooth to connect to any other Bluetooth device. Joting deliberated limited it.. Don't know why. But all you have to do is change to seeing from the current default (which is set to '1') to 0. and viola! You can see and connect to other devices..(led controllers,other obd2s, game controllers,...etc) and best of all you can now see these devices under the Bluetooth setting in the Android setting. Yep. They all show up normally now. Cheers! Courtesy of 4pda.
[FYT Android Head Units] surfer63:
Can you please explain a little better?

"But all you have to do is change to seeing from the current default (which is set to '1') to 0. and viola! "

I don't understand this at all. :confused:
[FYT Android Head Units] ojuniour:
Since this a one of those things that people wanted , I am going to make a new topic to give full details...

You have to be rooted first..then go to the root directory, them oem folder, them in the config.txt you will see a line (i forgot exactly ) but something like..com.fyt.bt = "1"

set it to "0"

and then save and reboot.

if you have the new latest updates, the bluetooth setting in the android menu will disappear (at least on mine it did).. you can use a third party tool to show the bluetooth setting if you want to see and pair devices from there.

Or you can just use the conventional way .. (the default bluetooth app )

on the 4pa forum, I read if setting it to 0 doesn't work you can try different numbers up until 5.

Please give it a show and let me see if it works for ya. :)

Where can I find spare parts for these radios?

[FYT Android Head Units] surfer63:
OK,

So it is config.txt in /oem/app and the value is "sys.fyt.bluetooth_type=1".

For those who are rooted they can follow [MENTION=2341615]ojuniour[/MENTION] method.

For those who are not rooted (like myself as I don't want it): That is also a very simple action. (Edit: and also rooted users can use that method)

Unzip attached zip file to a clean USB-stick. It only contains the config.txt and lsec6521update. Use this to flash your device. It will be a superfast flash only updating the config.txt (please don't fear the maybe scary messages about "resetting to factory defaults". I does not do that, it is just a message from the flash program for a "normal" flash).

It is actually the exact same approach as I described in "Modding your Joying/FYT SC9853i unit without root" in the first 3 posts.

The config.txt contains the value "sys.fyt.bluetooth_type=0". Simply replace by 2-5 if it doesn't work and flash again, like described in the 4pda topic [MENTION=2341615]ojuniour[/MENTION] referred to (Thanks again for that).

Note: After reboot I took my bluetooth keyboard in the car and tried to connect with the BT app. It did find the keyboard and wanted to link it, but stayed on "linking", without actually linking.

So I installed "Bluetooth Pair" from Waylon Huang (simply the first in my search in the play store) and with that one I could successfully pair my BT keyboard (and type 10x as fast as with the onscreen soft-kyboard)

More tests will follow.
[FYT Android Head Units] mjd1975:

The SPDIF out is from the SC9853I or from DSP BU32107EFV?

On my head unit there is no SPDIF out and I want to add it.

[FYT Android Head Units] Guyzer73:
Afternoon All,

Haven't been here for a while as things seem to be working well with the head unit (there we go, jinxed it now :p), however, I have one question.

Is there a way to set TuneIn Radio, or another IP Radio App as the default media app? Currently, TuneIn is not recognised as a media app and therefore I can't set it as a default via the settings app. Is there another way, or a streaming radio app that can be set to default?

Would be useful for me as I use this in lieu of the built in FM radio.

Cheers

Guy

Thank you for the effort though this sadly does not seem to solve the issue that most Bluetooth devices remain useless when connected.

I am trying to connect a super simple Bluetooth remote (Volume +/-, Forward, Back, Play/Pause: here is a pic of the remote:

Can this work together with units using canbus steering wheel buttons?
[FYT Android Head Units] surfer63:
I also have one which connects to the key wires. Please note though that if you have a CANbus models, you don have key-wires.

Only the latest ones that are now being sold by Joying have both. That is how it should be and how it should have been for the past years.

I have a Skoda without steering wheel buttons. As it is a Skoda (or Volkswagen or Audi or Seat), Joying only sells models with a Can bus. So I had to request a universal model to be able to use a 3rd part SWC module. But that means I do not have CANbus functionality in my unit.

And now, very recently, they sell units having both connections.

---------- Post added at 08:42 PM ---------- Previous post was at 08:40 PM ----------

Like I just explained: No!

Only if you have a model before 2015 (or so) or a new model after Feb 2020.
[FYT Android Head Units] rigattoni:
Sorry, in the moment I have no idea. In the moment I have no access to a car with CAN-bus buttons.

My car uses CAN-bus adapter which is connected to "KEY1" and the additional one on "KEY2".

The CANbus adapter is actually an AD-converter.

[FYT Android Head Units] blinger:
I wonder if these key wires can be pinned in the older canbus units wiring harness. Do you have the pin locations of these key wires in your wiring harness?
[FYT Android Head Units] surfer63:
No, they cannot. Of course I tried that :)

They are the brown and the pink wire.

It is either a digital set of pulses (CANbus) or a analog resistance/Volt signal.

I even asked Joying if I could change the behavior of the unit and it can, but you have to resolder a tiny resistor on the motherboard to change it from CANbus to universal. I did not want to do that (did not trust myself enough), but it also means that afterwards your CANbus does not work anymore.

I posted that somewhere in these XDA threads about the PX5 on how to do that.
[FYT Android Head Units] andTab:
That would not work with my car (no cup holder like that).

What would I need to look for in a remote to get one that would work with my Joying model? (Joying Latest 7 Inch Single Din 4GB+64GB Android 8.1.0 Car Media Player with Built-in 4G Module / SKU: JY-UOS03N4GS)

Need help

Hi, I'm new here.

I got an unbranded intel sc9853i with 4GB/64GB HU

(this one: a.aliexpress.com/_B0qeUx)

I already flash it with Joying Official ROM, cause of the app, which allows for button colour changing. I couldn't set them completly red. Red was kinda pinkish and there was no chance to set it more red. So i decide to flash that ROM.

Everything working perfect right now, I got the buttons set to full red colour, except now I got a line at the top with a message: "UI AND MCU DOES NOT MATCH (JY)"

Is there anyone, who can help me resolve that problem or help me with rooting this device.

Or maybe You will help me to find a way to flash the MCU firmware to the Joying one, cause I'm keep getting an error, while I'm trying to do that. I think both, the one I got installed on my radio right now and the new Joying one are excact the same one. The names of them are almost the same, I mean all the numbers and the latters are excact the same, the only difference is the beginning of the name, my radio's MCU name starts "KEQ" and Joying one starts from "JY". That's the only difference. And like I said after flashing it with the Joying ROM everything works perfect, like it should.

Thank You
[FYT Android Head Units] surfer63:
The unit checks for a manufacturer id. For the Joyings it is "ro.build.fytmanufacturer=43". This is in the fyt.prop in the Allapp.pkg.

From a terminal on your unit do a

getprop | grep fytmanufacturer

and see what it returns
[FYT Android Head Units] Konradziontko85:
IT shows excact that one

"[ro.build.fytmanufacturer] : [43]"
[FYT Android Head Units] surfer63:
So did you also flash the MCU file one from the Joying site? https://drive.google.com/file/d/1C-Pkr8sFmYdZOMaew9ZF9_gegjZp_3Tr/view

If not yet, you need to do that.

[MENTION=2358025]mclaudio[/MENTION] has a Zhan and is now also 100% on Joying. He posted a link to 4pda on how to make your unit 100% Joying, but it is not a link to a post, but to a poster who posted 540 (or so) posts.

So you might ask him directly and post back here on the results.
[FYT Android Head Units] Konradziontko85:
Hi again

I already solved a problem. You were right about changing that number in fyt.prop file. The file is in root/oem/app/ folder, so first You need have your unit rooted. But You need to change it to number "0" instead of "43". Like You said "43" is for Joying Unit and "9" was for some other brand. It was something like (PCPB) or something like that in that message instead of (JY). But "0" resolve my problem. Right now everything working just perfectly without any problems. So now I've got a 100% Joying Unit, it is rooted and even the "JET - Joying Extra Tools" are working on it.

One more thing... If Come about flashing Mcu with the OEM Joying Mcu firmware, I was not able to do that. I think the firmware is locked to their OEM units only. But like I said in post before it is excactly the same one, so there is no need of flashing it.

If some ody will want to do that with his Unit I can write some step-by-step instructions how I did it.

serfer63 thank You for your Quick response and Your help. I'm really appreciate for that.
[FYT Android Head Units] mclaudio:
HI. I flashed Joying MCU with no problem, only lost light on soft buttons.

if someone have zhan MCU i will appreciate
[FYT Android Head Units] Konradziontko85:
If You will tell me how i can get it from my Unit, I mean how I can make a backup of it then I will post it here.
[FYT Android Head Units] surfer63:
Having no light on the soft buttons (hardware buttons) is an issue many users have including myself. It is a bug in the latest firmware. So no issue with the MCU version.

It still works with day/night settings, but that means from 19:00-07:00.

With car lights settings it does not work.

I connected the ILLUM wire to my ACC (ignition) wire. As soon as I switch on contact, I have backlight on my buttons. I rather have always light in the buttons than none at all.
[FYT Android Head Units] Konradziontko85:
To be honest my backlight works as it should. I flashed it with the lastest Joying firmware, but still have my OEM MCU firmware and it's getting the signal from my car light switch thru the CAN-BUS Decoder. So the backlight of the Unit works with my car light switch and the rest of the car backlight.
[FYT Android Head Units] mastrv:
For those with issues where GPS cannot fix a location, I had an issue on my phone like that a while ago. In summary, the issue is related to NTP server synchronization. NTP servers provide time to requests made to them. When there is an issue accessing the ones that are set up on your device, there is an issue determining your location. There is the suggestion that the set up is too general, so it works for anyone anywhere, which causes problems. Here is a section of the explanation of some info found here on XDA at https://xdaforums.com/showpost.php?p=11342772:

What I found, in another post, was to modify gps.conf found in /system/etc directory. Modify to comment out "NTP_SERVER" lines and add one with NTP_SERVER=127.0.0.1

Information about this can be found in the following two posts: https://xdaforums.com/galaxy-note-3...fix-gps-users-ntp-to-localhost-t3531891/page2 and https://xdaforums.com/showthread.php?t=1239713

There are advantages and disadvantages to using 127.0.0.1 but I did that on my phone and the GPS fixes are very quick now where they did not happen at all before the change.
[FYT Android Head Units] surfer63:
You are completely right. I should have mentioned that. It does not work for many NON CANbus users. So users having a universal unit.
[FYT Android Head Units] feket663:
Thanks for help, but unfortunately I cannot put my device to recovery mode... I'm a simple user...
[FYT Android Head Units] mastrv:
You don't need to go into recovery mode. These Android head units do not have a real/typical recovery mode, from what I understand. The other posts were for more information.

You need to be able to modify the gps.conf file in /system/etc directory.

As mentioned, you need to modify gps.conf found in /system/etc directory to comment out "NTP_SERVER" lines and add one with NTP_SERVER=127.0.0.1

Any line that begins with "NTP_SERVER" needs to have a "#" placed at the beginning of the line. And, just before those lines, add a new line that has "NTP_SERVER=127.0.0.1"

If you have root, you can edit the file directly. If not, then you or someone needs to create a package that either replaces this file completely or modifies the existing file. I haven't created one of these packages yet, so I'm not sure of the steps.
[FYT Android Head Units] feket663:
I just don't understand why it worked for almost a year without fail? Few weeks ago I updated the firmware, then it worked for a while, thenthe GPS signal was gone.
[FYT Android Head Units] mastrv:
Yes, that's a good question. What I'm suggesting will eliminate a possible an item that may be causing your issue.

Possible reasons for an NTP issue include:

recently installing a VPN, which makes the NTP server response times increase

the configured NTP servers are getting increased load, which increases the server response times

there are some issues with the configured NTP servers

the method that you are connected to the internet

the speed of your internet connection and congestion on the internet

Quick question...are there times during the day where the GPS fix does happen or happens much quicker?

Note that since people are located in many different places, their responses from NTP servers may be different to yours. Also, you shouldn't have to be able to connect to the internet when you get a GPS fix, but it does make it much quicker. Here's another interesting read: https://stackoverflow.com/questions/8308412/gps-how-ntp-time-injection-works

From your description, it seems that you have multiple satellites "responding" so a GPS fix should be possible. That is exactly what I described. On my phone I had many satellites connected but could not get a GPS fix. Doing the steps I suggested fixed my issue. It may not address your issue, but it will eliminate it as a possible reason for your issue.

Any way...I'm just letting you know some info that I came across and that actually addressed my issue which sounds like yours.

I want to reset my radio joying and tried to do it by putting the firmware by usb but it does not reset the radio and does not erase the data by restoring it from the factory. any solution?

Enviado desde mi Redmi K20 mediante Tapatalk
[FYT Android Head Units] surfer63:
To start with: You are in the wrong forum. This is the Joying SC9853i forum. Specifics for your 8227 unit are not in this forum thread.

This is not a simple app or switch or whatever. It takes (quite) some work. I have this not installed myself. I had a look at it a few months ago when I got my new SC8953i unit. But I found it too much work and just sticked to the rear view camera functionality.

First some generic electronics for a rear view camera (which you can skip if you know it already):

If you connected your back camera "correctly", it is connected via the tail lights. That means that if you put your gear in reverse, the tail lights get 12V power and start burning. So at that time, your camera gets power as well and starts to work. When putting your gear in reverse, the same power is put on that "reverse trigger wire" (orange/white orange for Joying) on the back ofthe unit and the unit detects: "Oh, 12V on the wire. Show the reverse camera". This is purely electrical/mechanical: nothing Android or other fancy stuff. And that is also why you have to switch on/off that checkbox in your System settings in case you do not have a camera connected. This is not to switch the camera on/off. This is to show the camera, if connected, when 12V is put on the wire.

See the first 4 minutes of this video: https://www.youtube.com/watch?v=Qh-crI3LAg8 for some more explanation on above and on option 1 explained below.

Now if you want to see the camera at any moment you have two options (as far as I know).

If you still have an AUX-in, you can use an Y-cable splitter for video. So one end gets connected to the normal Video-in, the other into the AUX. Your video app can then show it. Note that AUX will switch of other sounds like radio/media player when you switch to the video app. It doesn't know it is only a video. In case of a movie it can be audio as well. (There is an app though that can do this and only use the video. It was in the gtxaspec custom rom). But in this case you need to connect the camera to ACC power so it gets 12V when you turn ignition on. (This can be a bad idea as some of these small cheap cameras can become quite hot when constantly being on, meaning shortened life expectancy or even fire hazard.) Also in this case your unit should receive a 12V signal on its "reverse trigger wire". This means that when you put your car in reverse it will show the camera.

Option 2 is an override harness. You have these for reverse camera only, but also for a reverse and front camera giving you the option to switch at any time to either front or reverse camera. See this video for example: https://www.youtube.com/watch?v=dgsV0uTiYr0 (just picked the first I could now find. There are more).

So is it worth it, work and money wise? I don't think so. ;)

Edit: And if you just want protection from tail-gating or accidents from behind, even when parked, you could also install a (2nd) separate dashcam at your back windscreen. One with parking mode and G-sensor. This one will not be connected to your unit (or maybe it can. I don't know)
[FYT Android Head Units] yzf750:
On a Ford F150 it works. I have my factory rear camera wired to my Joying unit, and all I have to do is push one of my factory buttons on the dash and the rear view camera comes up on the joying screen when not in reverse, using just the factory wiring to the head unit. Guess it depends what vehicle you have. I'm using the PAC Ford Radio kit on mine which assigns a button on my dash to send the reverse signal to the headunit any time its pushed. You could very easy rig a switch up also to the headunits wire to trick it also at anytime. No you cant control it from the headunit as it requires this external trigger , but the OP wanted to "view" the camera when not in reverse which is easy to do.
