Can anyone running this ROM please confirm is apps are able to see Bluetooth devices? I installed this ROM a few months ago, never having tried the original Joying ROM. The problem I am having is that apps that directly communicate to BT devices are not able to see the devices. For example, I have an application named ALP Connect which connects to my radar and laser detector via BT dongle. The apps scans for the dongle and cannot find it. Also, I have an August Home smart lock, the August App cannot find the August Smart Lock either. Oddly enough, if I open the Android Bluetooth menu, both devices can be seen and paired. For some reason, the apps themselves cannot see the BT devices, but the OS can. I have verified both these devices work just fine when using my Google Pixel phone and no pairing is necessary for them to work.

Here's how we handle clock speed during installation of the gtx rom:

once TWRP is loaded, we increase the clock speed to max, for the duration of the installation.

[ on 5009 this would be about 1ghz, and on 6021 this is 1.2ghz. ]

During my testing, with both 5009 and 6021 units, we ran with a special background script to increase CPU load on all cores to 100%, the intel CPU would hit 100C, WITHOUT any reboots. This was done maybe a dozen times during testing on BOTH types of units.

The only way we could reliably produce reboots during installation, with or without loading the CPU, was with an un-reliable power source. Any dips on the B+ lead, or low voltage to begin with, resulted in a reboot almost every time we attempted installation. Our original PSU was a 12V 2Amp unit, which when tested, was actually 11.45 @ 1.67 amps.

check your PSU. if in the car, have the engine running during installation.

I have the 2018-01 stock firmware. My MCU is 2017-05-25. There are 2 versions of stock firmwares. Old and new MCU. Can I install stock firmware with MCU 2017-09-20?

Is there a way to stop google play service constantly crashing in background?
[FYT Android Head Units] lotte67890:
Have a look some posts above, I had the same issue cause obviously joying did not have the newer MCU included in there FW package. I first downloaded the FW on first of April and yesterday downloaded the same file again, and voila, my MCU is now 10-25.

You may find the correct Version here: https://www.joyingauto.com/blog/category/updated-files-released?page=2 but make sure that you choose the correct Unit and Display size!

[FYT Android Head Units] ruriruri:
Interesting. The way I solve the bootloops is turn off the car overnight. As post #1819 mentioned. It boots straight into GTX next day. I had to do it over 3 night to complete first boot. Because hot CPU seems to stuck/slow down the first boot.
[FYT Android Head Units] lotte67890:
OK, I´m in the game... I now attached a heat sink and a small fan and now I could install this ROM without a hassle and also after a reboot the Unit comes up with more than 10 degrees less.

I´m also able that my Creative Soundblaster Play 1 USB DAC can be Volume controlled when playing mp3 files. :good::good::good:

What does not work so far:

Bluetooth Audio does play out over the USB and the internal AMP, is there a way to prevent the Bluetooth Audio to play out internal?

The Display stays on all the time, the timeout in the Display setting does not change anything... (currently 1 minute)

Is there a way to get the Android Volume status to the status bar (and maybe hide the Joying Audio)?

Thanks for your effort!!! I really appreciate!

[FYT Android Head Units] KlaverBoer:
My unit also started with the same problem as you describe. But it will become worse. Just wait and see. My digitizer totally doesn't work anymore. Joying said that they will replace my unit with a new one, but it will cost me € 100,-. They also said that the possibilty that the problem will come back was very high. So i saved my money and bought a touchpad with integrated keyboard from aliexpress. That works fine for me. I bought this one: https://nl.aliexpress.com/item/H18-...482.html?spm=a2g0s.9042311.0.0.7fc64c4dDcCkb9

I was messing around with my HU yesterday and I'm now also stuck in a reboot loop/boot loop (the google animation loading infinitely). My steps to get here were:

1. install newest custom apk from microSD.

2. Install custom recovery

3. install GTX with "keep data" and enabled and reboot (didn't seem to reinstall though)

4. In custom, enabled CPU 100%

5. Installed some sofiaserver stuff

6. Rebooted and stuck

The unit got really hot, tried pulling the plug and rebooting a couple of times. Nothing seems to do the trick. Any tips?
[FYT Android Head Units] tOz666:
I've followed [MENTION=520205]gtxaspec[/MENTION] directions and I finally solved bootlops.

First I put a cooler on my SOC to actively cool it

And then reinstalled gtx ROM while the engine was running.

No bootloops since then, and I've made 5-6 reboots while installing my stuff (sofiaserver mods, xposed modules, etc).
[FYT Android Head Units] wanb1i:
Agreed, but if you do get a bootloop w/engine running, reset with the reset button 3 times, unit will then boot into GTXROM.
[FYT Android Head Units] Beatwolf:
OK so reset it 6 times in all, engine running, still shows the google logo indefinetly. Upon first turning the ignition after a long pause I had a black screen and something l ike "wait here for error"... The cpu and inside still seems to get realllyyy hot...could I have bricked it completely?

edit: just realised I am retarded and actually updated Xposed....verdammt :P
[FYT Android Head Units] lotte67890:
Try to cool your unit, I'm quite sure that this will solve your problem... Use a heatsink and a fan, helped me solve the installation problem...
[FYT Android Head Units] tOz666:
I encountered some problems with Google Play Services, it won't update, Play Store says "Error 504" when trying to update.

I've tried so many times to download and always had the same result.

EDIT: I solved this by installing latest opengapps nano x86 using TWRP.

BTW, to enable "performance mode" of custom.apk, reading the sources I've found that it disables thermal throttling by renaming /system/priv-app/ituxd/ituxd.apk

And also writes something to /system/bin/install-recovery.sh

If I want to disable performance mode, I just need to rename /system/priv-app/ituxd/ituxd.apk.old back to /system/priv-app/ituxd/ituxd.apk , and then get the original install-recovery.sh from gtx rom zip and put it to /system/bin (checking permissions)?

It worked. .finally my HU is back up and running again :) Now though I keep getting an error when trying to update google play services (which is pretty much necessary to run gmaps): "'Google play services'" Can't be installed... (error 504)... anyone know how to fix that?
[FYT Android Head Units] tOz666:
Refer to my last post https://xdaforums.com/showpost.php?p=77188516&postcount=1874

I've solved it installing the newest gapps via TWRP:

Download (on the HU and then browse it, or on the PC and put it on a USB stick) the latest opengapps for x86 platform, for android 6.0, nano variant, on https://opengapps.org/

Open gtx custom app, install custom recovery, and then boot to TWRP using the button.

Pick install and browse the zip you've just downloaded (on internal storage if downloaded on the HU, or USB OTG if on a flash drive), it will install latest opengapps on top of the existing ones on gtx rom.

Nano package always includes the latest Google Play Services, and hopefully when new versions of Services are issued, this time they will autoupdate, if not, you have to repeat the process of installing latest opengapps again.

Just installed GTX on my Ford style 3gr and each time it boots, the screen shuts off during the Android splash screen, and only sporadically comes back on. I can't get through the setup process. I need to know what to do from here. I'm on my 5th or 6th reboot trying to get some lever of stability.

Edit: I'm seeing the number of heat related issues, I'm going to let it sit until tomorrow.

My unit booted this morning.

It would seem wise not to sustain full cpu usage on units that are already prone to overheating.

At the very least, add a note or disclaimer on the initial post about the potential for overheating during installation.
[FYT Android Head Units] surfer63:
That is not activated by default when flashing the ROM.

You need the custom apk to switch that on, otherwise it is "simply" running in performance mode.

[FYT Android Head Units] biggy238:
Post 1862

Even if I'm misunderstanding, it doesn't change the fact that multiple users are experiencing non-responsive units during or after install, and is remedied by letting the unit cool. I'm not savvy enough to be critical on why it is the way it is, only requesting that it be post in post one, not post ~1860.
[FYT Android Head Units] gtxaspec:
The working theory right now shows this might be caused by unstable voltages during installation...just as a precaution I'm going to release a new version of custom with some changes that will clock the CPU down.... And see how it effects installation time and stability...
[FYT Android Head Units] biggy238:
Thank you for your work and continuous improvement. I was Key On Engine Off, but had enough voltage that the ford's modules had not shut down (typically 9+V), and I was able to start the engine.

Side note, I am having a popping and time signature slow down in V4A. I didn't experience this with the same V4A on the stock rom.

I deleted the driver, and cleared cache/data on V4A. I'm not having the slow music, but it still pops.

It's mostly with poweramp audio playback, but Google play music was also popping.

I also can't get the clock to adopt network time, on my homes wifi or via cellular tethering. I turned off automatic date time settings.
[FYT Android Head Units] D3LTA:
V4a doesn't work in this ROM, tried pretty much everything but can't get it to work properly.

Pretty shame because that's the most wanted feature of the headunit if you ask me.
[FYT Android Head Units] Beatwolf:
Thanks this method worked great.

NowI have a new issue however, since reflashing my unit it's not going into sleep mode. When I leave the car with keys out for more than 10 minutes it does a full shutdown. This in a VW Golf V. I only have the no-kill gutsden mod installed, and a few radio and bluetooth visual mods and am running Nova launcher. I tried uninstalling sofia server and the no-kill mod, but that didn't do anything. I know that some app is supposed to be causing this, any idea which one? This used to work fine. I believe I am on the january ROM (the one that is linked in OP).
[FYT Android Head Units] sterod:
Is there anyone who can confirm this please? Be it on this ROM or stock, I really need this BT functionality and its more important to me than running this ROM if it works properly on stock.

Hi, I have a dude, I have already rooting but I do not understand the next step:

"Due to Bluetooth, WiFi, and as well as nvram patches in the ROM and bootloader, you must be running Joying 6.0 firmware dated 2017_12_15 or later to install this ROM."

I have a ROM original Joying, I leave you the ROM:

Install one of the "wake lock" apps from the play store. They will tell you which app is keeping the unit awake.

Yes, you first have to upgrade your Joying firmware. Your current firmware version of 5 July 2017. It is too old.

Hey guys, question I've been meaning to ask for a while... I installed this ROM several months ago and it's been working perfectly, except for a couple small things...

First, when streaming music through Bluetooth from my phone the music slows, cracks, pops etc. I remember this being an issue on stock Joying after an update, then they fixed it. I've tried applying some of the Bluetooth mods in the extra tools, but nothing seems to fix it.

It's only when streaming audio, calls through BT are fine and work perfectly.

Second, when using the navigation, it works and finds my location, but isn't fluid... like it updates every 5 or 10 seconds. Like I'm here, then here, then here... instead of just one continuous flowwwww...

Hoping someone can point me in the right direction as this ROM is waaayyy better than stock...
[FYT Android Head Units] surfer63:
Do you have a fan installed? or better: a fan and a heatsink?

It sounds you have overheating problems, especially when you mention the lag in your navigation.
[FYT Android Head Units] mooch530:
I don't have a heatsink or fan, but I don't think that's the issue... I mean this used to work fine when I first got the radio before the Joying V.6 (I think) update...

More interested in getting the Bluetooth issue fix anyway...

Thanks!
[FYT Android Head Units] biggy238:
Just lost my screen after 1.5hr of nav with Waze. I guess the only way to run this rom is with hardware mods?
[FYT Android Head Units] Need4Camaro:
Surfer is probably right about the overheating problem. These units are noctorious for this issue. When it overheats the CPU cuts the speed in half and bogs down anything running on the unit until it cools down again. You need a heatsink and fan. I had to install one on mine to fix this issue.
[FYT Android Head Units] surfer63:
Thanks. :) Yes, I'm pretty sure it is overheating. Same could be valid for the bluetooth issue. If the unit drops to 600 MHz or 416MHz, all apps and the entire system slows down, also bluetooth and the system processes behind it.

Thanks guys for the great support!

Since I installed this ROM (on my Sofia, 2017-10-25) I can't have sound of my cell, it pairs with no problem, when my cell rings the phone app on my joying opens, but no sound comes from it. I tried changing names, PIN pairing, but nothing solve it.

I was using it with no problem before installing this rom.

My cell sends audio to another device like a speaker bt with out problem.

I turned the "OK Google" listening off, but nothing fix it.

don't worry is not a big deal.. just take of the lid, use thermal compound + epoxy and stick it to the IHS.

I also recommend buy a 5v fan from aliexpress, 3€ more or less... and paste it with a heat gun over the heatsink.

I can't seem to work around the - 504 error in play store. It started because Google play services refused to update.

I flashed Gapps nano, which took care of Google play services, but now I can't install SwiftKey, it always exits with a -504 error after it downloads and attempts to install.

I've cleared data/cache on Gplay, Google framework and Gplay services.

Storage shows I have 28gb left, so storage shouldn't be the cause.

Installing GTX ROM on JY-tl123n2

Hi Guys

Any help would be appreciated.

I have had a tough few days recovering from soft brick after installing xposed.

I got out of the bootloop by restoring to a Jan 2018 provided to me by Joying some time back.

Rooted the unit, began the Android helper application "custom" to install and selected INSTALL CUSTOM - Installs superdave's custom recovery.

Had the GTX ROM on a usb stick.

Unit rebooted, lights began furiously as in the demonstration video. I didn't get the teamwin splashcreen but rather the green Android and a progress bar.

This ran for over an hour and I got bored and figured it can't be correct.

Flashed back to the Jan 2018 ROM and mostly up and running, except I can't update the google services because of the dreaded 504 error which I can't resolve.

My device

-------------

Model: JY-TL123N2

Android ver: 6.0.1

CU: 2017-10-25 19:26:31 JY_(R76)_90xxx

CPU: Intel ATOM 4Quadcore(x86)

Resolution: 800x400

My questions

----------------

Is my device compatible with 5009_gtx_v9_alpha_3?

I'll root before running again: Is that correct?

How long should the process take after booting?

Is it better to use USB of flash? Does it really make a difference?

If I have installed xposed at some point do I have a way to get back to the old google framework?

Cheers,
[FYT Android Head Units] biggy238:
No, it's not a big deal to do, I just didn't expect to have this much trouble just from the rom change.

[FYT Android Head Units] ptolomeo:
I think the ROM is pretty stable already. I only suffer random cold reboots but nothing that annoys me.

I've had some overheating issues with the unit (even though I live in the fresh North of Spain, I had seen the Joying temperature going up to 93ºC !! even though I have the heatsink mode and replaced the top cover of the headunit with an aluminium grid) so I ordered a fan but unfortunately didn't receive it before my three week summer trip to (hotest) southern Spain.

I was very concerned about the overheating problem.

Anyway, it has been working flawlessly this vacation (Google Maps + RadarDroid (to avoid speed tickets) + PowerAmp and ocasionaly Shazam and a radio app), for over 2,000km drive, and temperature didn't reach 70ºC at any moment.

I think the reason is because in this trip I had to go all the time with the aircon on, while driving in the north is not necessary. My car is a 2009 Passat, so I guess in most of the VAG cars, overheating can be reduced if the aircon is turned on.

Just my two cents.
