Hi There, THanks for the advice, i've installed it and got a bunch of logs. What should I be looking at to know if it's FYT based or not?
[FYT Android Head Units] brs19301:
How to Update?

How do I know what version I have installed (did it years ago - so it i seems) and what is the most current version?

Also, occasionally the unit will boot up into some sort of update mode and hang (see pic). Pressing RST takes care of it. What is this about?

Is there a original dab+ app from joying?

And where can i find this on this rom?

Edit. Found it
[FYT Android Head Units] Doume59249:
Hello,

I've a head unit coming from China.

It's already rooted by myself, and it works.

I ran your tool HWGetInfo to know if it's a compatible FYT or not...

You'll find attached the resulting HWget_info.zip

Thank you to help me , to identify :

- Which recovery I can use to backup... (CWM or TWRP)

- Which ROM I can install without risks to brick it !
[FYT Android Head Units] surfer63:
It is indeed a Sofia 3GR compatible FYT unit with manufacturer/reseller id 39. I can't remember if I have seen 39 before.

I do not know of any CWM recovery available, but the compatible TWRP recovery can be found or installed via the custom.apk

Theoretically you can use this custom ROM to flash your unit but there might be issues. The MCU can sometimes be quite different leading to severe issues. The builder of this custom ROM very rarely visits this forum anymore. He knows really all the ins and outs of the several options.
[FYT Android Head Units] Doume59249:
Thank you very much for your answer.

Some hopes are back ! :o

I found custom.apk, and I've installed it.

I imagine the first step to do is 'reboot in TWRP mode' ? to make a backup of stock ROM ?
[FYT Android Head Units] surfer63:
Yes, but I'm not 100% sure whether you can also restore it. I am not on the Sofia anymore for about 2 years now.

The best is of course to have a firmware from your reseller.
[FYT Android Head Units] Doume59249:
I just sent a message to reseller, to ask him an access to stock firmware package.

But I don't really have hopes....

Wait & see !

Thanks for all.
[FYT Android Head Units] slakosd:
Thanks a lot for this ROM and all the people that have developed xposed modules and Sofia Tweaks App. After a couple of years my head unit finally works just like should. Now it's fast, smooth and have custom mods that make It perfect for me. I'm thankful with us. Regards from Spain.

[FYT Android Head Units] Ski.Freak:
GPS speed calibration

Well... I decided that I would install the GTX ROM, as I really wanted to resolve the GPS speed calibration issue.

The ROM was successfully installed, but despite installing GPS fix (using JET v74), which reported being successfully applied, I am still seeing the speed increment in 4km/h steps.

I have rebooted the unit a few times, but this has not changed anything.

Any suggestions as to how I can resolve this issue?

Another quirky thing I have noticed, with both the standard Joying and GTX ROMs, is that the text to speech notifications/directions do not work for the first instance.

The radio volume decreases, but no voices are heard. On subsequent alerts/directions it does work, which is a bit weird.

Also, with the GTX ROM the radio widget no longer exists. I used to have that on my home screen, which I liked.

Is there a reason why the widget no longer exists? Is there any way to get it back when using the GTX ROM?
[FYT Android Head Units] Ski.Freak:
I was of the understanding, falsely I now know, that when I installed the GPS fix that it would just work, but it doesn't.

Little did I know that I also needed to go into the Xposed framework settings and enable the fix. Did not see that mentioned anywhere...

Anyway... it's working now. :)

I would still like to know if it is possible to get the radio widget back, as I really like having it on my home screen.
[FYT Android Head Units] surfer63:
The radio widget is not part of the radio app, but of the Joying launchers. The GTX Rom uses the Nova launcher (as far as I can remember).

If you switch back to one of the Joying launchers, which are still in, you should be able to reactivate the radio widget.
[FYT Android Head Units] Ski.Freak:
Yes, the Nova launcher is preinstalled in the GTX ROM, but I am currently using the Joying launcher, however the radio widget is not available.
[FYT Android Head Units] Ski.Freak:
Radio Widget

I have tried going into Car Settings > Spanner/Screwdriver tab [enter password]> Home Launcher Selection [enter password], where there are choices of UI02, UI03 and UI04 (I am currently using UI04).

Tried them all, with a reboot each time, but none give me the option of the radio widget.

I see that in the JET app there is an option to upload a different launcher.

If, as you say, the radio widget is part of the Joying loader, is it possible to get that APK and to reinstall it via JET?

if so, where can I get that APK?
[FYT Android Head Units] surfer63:
I really wouldn't know. They "should" be in the launchers.

And in the JET apk you cannot upload a different launcher. There are multiple mods, but launchers are not part of those.

[FYT Android Head Units] Ski.Freak:
So... any suggestions on how I could get the radio widget back???
[FYT Android Head Units] Ski.Freak:
Anyone???
[FYT Android Head Units] mannas:
Can anyone help me? I use this rom for almost a year now but a few days a go after a reboot it got stuck on a bootloop. I've been trying to restore stock via USB pen drive but every time it runs the original it gives me an error.

E: Failed to Verify whole-file signature.

E: signature verification failed

[FYT Android Head Units] surfer63:
Most probably an error on your usb-stick. Did you "safely" take it out of the used devices?

Format it again and put a fresh firmware copy onto it.
[FYT Android Head Units] thebest19:
Hi !

I've got an intel sofia unit, but i don't know if this rom will be ok .

It's rooted .

You'll find attached HWget_info.zip

If this rom is ok, will I loose external temperature and the fuel consumption app when pressing steering wheel control ?
[FYT Android Head Units] surfer63:
According to gtxaspec the rom is compatible with any FYT sofia. One thing that might give some issue is the MCU software.

The HWgetinfo shows not really which hardware is in the unit, but more whether it is a FYT and therefore compatible.

I have no idea about your last question and what the steering wheel button has to do with fuel consumption app.
[FYT Android Head Units] thebest19:
Thank you for the information

I justed wanted to know if this rom have a fuel consumption app,

My unit provide informations from the car (like consumption, mileage, temperature, error message) because it replace the original screen of my car

Downgrade to android 5.1

Hi

I installed this GTX joying rom V9a3 and work very fine but i want to downgrade to android 5.1 because i have TOMTOM 1.4 is not compatible with android 6 :(

Is there a GTX rom with android 5.1 ?

Thankyou
[FYT Android Head Units] surfer63:
No,

downgrading is not possible at all.

is there custom rom for :

eu-jy-vo130n4gs from Joying,

it's with a sofia chip the told me
[FYT Android Head Units] surfer63:
You do NOT have a Intel Sofia. It is an Intel SC9853i, which is definitely a big difference and they can't be exchanged.

There is no custom Rom. At least not yet.

you can root it and mod it to some extend.

See rooting

[FYT Android Head Units] tanlasmet:
Hello, I need help for my joying car radio model JY-VM130N2D which no longer starts continuously repeats app optimization. but it doesn't turn on. I asked qusle is the provision to enter recovery. thank you
[FYT Android Head Units] surfer63:
I guess you do not have coooling in your unit. A full optimize often overheats your Sofia unit. Get your unit out of the dashboard but keep it connected, remove the lid from the unit, switch it on and use a fan or hair blower (on cooling) to keep your CPU cool(er). See if it now finishes the full optimize.
[FYT Android Head Units] tanlasmet:
Thanks, for your answer, in fact I have no cooling fan, I will try to do as you told me. in order to enter recovery how do I do it? Thank you
[FYT Android Head Units] surfer63:
You can not enter recovery. This unit has a minimal auto recovery for flashing, nothing more.
[FYT Android Head Units] tanlasmet:
Thanks again for your answer, I thought that with a combination of keys you could access the recovery console. Thanks again and happy holidays.

I kinda f#@*ed my unit...

Hello all,

First of all... :svetius:for the dev and the guys helping him.

Before i tell you my problem, a lil' history... :p

So i have my unit for a few years now. A very slow unit... :(

Since i used it mostly for Waze, Radio and Youtube, didn't bother me that much until a few months ago when i asked Joying if there is an update. They gave me the link for 6.0.1, i updated the unit (no big improvement) and i was happy.

After about a month, it started to do dirty reflashes from time to time when waking up from stand-by.

Joying couldn't help me so i started to look around i found this thread.

I read most of the thread and i got really excited. I did everything by the book: rooted the unit, installed ADB over WIFI, installed custom, clean install GTX ROM, all the stuff.

THE PROBLEM:

- the install went dirty (i still have waze on the unit from previous install)

- i have no launcher and i am not able to set any though i see 3 in settings

- when i start the unit i get the message that setup wizard stopped, google partner stoped, google service stopped, ... stopped

- i am not able to start any app... i have it set as default app for the NAV button

- i was able to access the play store once cause i got updates for some apps, tried to install a launcher but i get the setup wizard stopped error

- from time to time i get radio if i am lucky :))

- somehow i was able to open the browser and tried to install apps from my drive... i get parsing error

I've tried giving every right to every app, rebooting, reinstalling the joying image from USB, reinstalling the GTX image from USB... without access to recovery. Nothing worked...

I've been playing with Android ROMs since 2012 on my phones without problems but now... this one is killing me :(

Any advice? Is there a way to boot in recovery mode?
[FYT Android Head Units] surfer63:
Bit late, but it might be the JY-1-C9-TimeWeather-V1.0.apk. It is much more than only Time and Weather.
[FYT Android Head Units] Ski.Freak:
How would I get hold of that APK file?

I have looked in the 5009_20 and 5009_60 zip files and it's not there.

Assuming I can get hold of that APK, what is the best way of installing it?
[FYT Android Head Units] surfer63:
gtxaspec removed it from the custom rom. It is in the original Joying Rom.

See attached the apk.

I would first try to simply install it.
[FYT Android Head Units] Ski.Freak:
Thanks... I will give it a try and let you know what happens.

Is this mod will work to my JY-VO101N4GS-R?
[FYT Android Head Units] IG_Vasilich:
in 1st post of this thread is described, for what units/SoMs this ROM is.

Noone knows what SoM your unit is based on, so - try figure out this first.
[FYT Android Head Units] surfer63:
It is the default unit with rotatable screen (the -R).

[MENTION=9809227]Android49[/MENTION]: But which mod are you talking about??
[FYT Android Head Units] Android49:
this custom GTX rom Sir!
[FYT Android Head Units] surfer63:
No. forget it. The custom rom is for an Intel sofia running android 6.0.1

It is completely incompatible with regard to both hardware and software for these SC9853i units.

(For me a mod is one apk. A custom Rom is something else for me and can of course contain multiple mods :))
[FYT Android Head Units] B3rt:
I installed this rom some time ago(not sure which version), i was looking if there is an newer version available

Where can i see which version of this rom i exactly have installed?

Are there any newer roms available with newer android (example android 7 or 8) versions?
[FYT Android Head Units] edit:
No and will never be an update... Consider this unit end of life.

Hope someone here can help - you all know more that me so i feel im asking in the right place!

I am really interested in installing the GTX rom on my head-unit as any speed increase will be most welcome.

I dont believe that I am up-to date enough to simply install GTX rom straight up:

Here is what version i am running currently:

[IMG="current version"]https://img.techpowerup.org/200513/img-20200513-163024shrnk.jpg[/IMG]

So, I understand I can obtain Joying's latest FW from the link in the post

but this has different MCU versions to download. How do I determine which version i need to install? if it helps, i have included details of which MCU version I am running at the moment:

[IMG="current MCU version"]https://img.xda-cdn.com/mjJHxbaU3PYzWcV1XBNegs1P8xs=/http%3A%2F%2Fpreview.ibb.co%2FcdgyWR%2F20171018_171843.jpg[/IMG]

So if i can determine which version I will need to download, thats the first hurdle i've passed!

Help is appreciated!
[FYT Android Head Units] surfer63:
The 525 MCU version is the 2017-05-25, so your MCU version is older. So you need to download the "5.25 or earlier".
[FYT Android Head Units] musje83:
Ok so I can't/won't scan through 234 pages of this thread, so let me ask straight up: how do I install this on my unit?

I have a Joying unit (JY-UL135N2) that has the Intel Sofia chip, of that I'm sure. But I know nothing about it beeing rooted or not, where to find the latest version of GTX's rom (on the first 5 pages of this thread I saw they already went up to v6, so not sure where it ended). Also, the first INSTALLER download link in GTX's 1st post doesn't work anymore.

Can someone please explain a bit about how to get started? Much appreciated :)
[FYT Android Head Units] surfer63:
You don't have to scan through 234 pages. Simply read post 1-4.

I still have a copy of the custom.apk See here.

The V9a3 was the last custom rom (see title of thread), but I don't have that one anymore. Maybe some other user.
[FYT Android Head Units] musje83:
Thank you!

In the first post it says

That's what I'm not sure about. Or can I download the Custom Rom from your link, put it on a USB stick and load it like I do with Joying's ROM? Theirs is automatically recognized by the head unit and asks for it to install, then 5 minutes later it's done.

Scratch that, main worry is whether or not it's rooted and what will happen once I use the 'CUSTOM' apk on the headunit.
[FYT Android Head Units] surfer63:
You need to root. Without it the custom.apk can't do anything.

When rooted, you can use the custom.apk to replace the recovery image for a TWRP recovery image, and back.

I think the latest version also allow you to install the custom rom if you have it on a USB-stick/SD-card.
[FYT Android Head Units] midd33:
I'm hoping someone still lurking in this thread can help me because I'm stuck. I've been trying to get Bluetooth to get connect to my radar detectors. I have it working on my other rooted Joying running Android 5.1.1.

For this GTX Rom, The bluetooth apps see the devices but the detector apps cannot connect. For my Valentine One Radar Detector, I use an app called JBV1. JBV1 sees the built in BLuetooth (It's an LE version, so no pairing), but it just won't connect. The stock app V1Connection doesn't see the bluetooth at all on this Rom.

The other ALP Connect doesn't see my NetRadar at all. But in Android, the bluetooth is discovered. That one needs to be paired.

I can't remember what I did on my rooted Android 5.1.1 to get them to work. I remember using the modified bluetooth file, BlueBallz apk and Bluetooth Auto Pair as they are still installed on the 5.1.1 head unit.

Any help is appreciated.

OK don't know where to ask besides here.

I have a Joying UL135N2 sofia Headunit. Half of the Touchscreen is broken. So I want to put in a new digitizer. Does anyone know the type digitizer? I see a lot of Gt911 digitizer so I hope that's the one. And I believe the cable should be in the middle? Am I correct And question 3. Let's say I ordered the right one. They talk about the orientation if the digitizer is registering left as right and vice versa. Can you change the orientation in the HU? Running GTX btw
[FYT Android Head Units] pwood999:
I searched all over the place for a compatible digitizer for mine. Ended up contacting Joying and they were very helpful, although mine was still under warranty, so only £20 for replacement. 5 days from payment to arrival in UK, and then 12 days to ship broken screen & get refund.

Email the support team with your serial number.

13th Aug : Paid £20 shipping plus £50 deposit for the replacement.

17th Aug : Joying posted screen & emailed tracking details.

22nd Aug : New screen arrived. (5 days seems pretty good for China to UK postage)

28th Aug : old screen posted back to Joying

10th Sept : Joying refunded deposit.
[FYT Android Head Units] andytuinman3:
Need to buy it myself because joying refuses to send a different one because they "don't support this unit anymore" so that's why I'm looking for a replacement digitizer
