[MENTION=520205]gtxaspec[/MENTION] is there a way to reverse performance mode in Custom.apk? I set it to performance and audio is stuttering, which is the same problem I had on a previous version where I had used kernel aduitor to set it to max clock speed. This on a clean flash of 9a3.

Otherwise I guess my option is to dirty reflash the ROM.

The other problem I'm having is that when I try to write to the external sd, I'm getting a document provider request to grant permission to the file manager. But document provider doesn't see the external sd cards in either slot. This has always been the case. I tried the HandleExternalStorage Xposed module but it doesn't seem to be doing anything.
[FYT Android Head Units] gtxaspec:
I'll release a new version to reverse tomorrow. What app are you using to write to the sd? I've never encountered an issue. Let me know so I can test and find a solution.
[FYT Android Head Units] joshnat:
Solid Explorer, but Amaze is doing the same thing. The Joying file manager was there on the first boot, but disappeared after TiBu restore.

Update: was able to write successfully to the external sd by doing a clean copy from the internal, rather than overwriting the files that were already there. Not sure why that would matter.
[FYT Android Head Units] Need4Camaro:
I went ahead and got the splitter type, it no longer shuts out my internal mic when I use it, however; still noone can hear me over the external mic and if I choose the external mic only..I get muted out.

Another issue has arisen...I chose the wrong MCU type for the unit. I have the double din universal unit 100% touch screen no buttons... Do you happen to know which MCU I'm supposed to select? I have chinese writing on the top of my screen, the touch buttons arent working, and no audio.

Edit: I was instructed to reload the factory firmware / mcu. I attempted doing so but no longer see a way of doing this, how do you go back to the factory firmware?
[FYT Android Head Units] gtxaspec:
no need to reinstall...what version of the rom are you using?

also, there is no option for external, there is POST mic or internal or something right? only one of the options works.

you may need a new type of microphone if it still doesn't work...
[FYT Android Head Units] ste2002:
Just FYI: by slightly tapping the plastic close to both external and internal mics I've found that they are both functional (my HU is still on stock Dec FW).
[FYT Android Head Units] WILD9:
I ended up installing this and first impressions are really good, thanks for the great rom!. couple of issues though - xposed wont install any addons, they just sit at "waiting to download" Ive sideloaded them instead though so not a huge problem.

The bigger issue is wireless seems to be dropping for no apparent reason. It drops the connection and then will not reconnect even manually until I disable and re enable wireless I read a few pages back a couple of other people were having similar issues, did anyone get to the bottom of it?

Will by trying this later, I was using it on a 5.0 rom and it worked well.
[FYT Android Head Units] Kaps:
I got an error of UI and MCU mismatch.

So I changed the fyt.prop, ro.build.fyt.manufacture to 0. This led to the issue.

Resolved it now by changing this to right value. I like the ROM overall for daily use.

Some issues:

1.) It takes much time to book

2.) Android is upgrading, updating apps on every startup whenever I start the car.

3.) Radio screen goes Kaput and flickers at times.

4.) Sometimes it hangs too much and at times it works so fast.

can you advise on some tips and tweaks ?
[FYT Android Head Units] walter79:
It works well with this app.

But did some get tethering work without this app?

I use this app to get internet connection from my mobile phone via bluetooth. Limit. max. 2Mbit/s (max. bluetooth speed but use less power)

[MENTION=520205]gtxaspec[/MENTION] can you add this app to /system/priv-app ?
[FYT Android Head Units] WILD9:
WIFI tethering/hotspot is working for me but as I mentioned a few posts up the unit is dropping the connection after a few minutes and not reconnecting which is frustrating.
[FYT Android Head Units] Kaps:
A factory reset helped solving above issues. Now only issue is Mic is no working on calls. Ok google is working but If i am making or answering calls using head unit, no audio / bad noise goes to other party.

Any suggestions ?

Thank you
[FYT Android Head Units] Need4Camaro:
Can you elaborate alittle more? How did you tap what plastic and where exactly? I know the internal mic is surrounded by the bezel .. is that the plastic you are meaning? And the external mic I'm unsure what plastic you're referring to

I went ahead and blew it away last night, reimaged with stock Joying and then went back to GTX and everything seems to be working as intended minus the mic issue.

I will go for a Joying MIC but don't know which one or where to get it.
[FYT Android Head Units] ste2002:
I tapped slightly against facia panel close to MIC hole (internal) and also against overhead lamp enclose where factory Skoda MIC was originally mounted then replaced with one from Joying.

I also tapped against other spots away from above two to make sure those do not give same sensitivity shown in "Sound Meter" Android app: https://play.google.com/store/apps/details?id=kr.sira.sound

[FYT Android Head Units] amadare:
Great rom thanks GTX. Haven't had any problems really. Joying UM128N2D here with a 3rd party backup cam, the factory external mic and a KONNWEI OBD2 Bluetooth adapter.

I have wifi tethering on my iPhone and Bluetooth for phone functions. I turn the tethering on my phone turn the key on and everything connects just fine.

I'm using carwebguru for my launcher.

Sometimes the obd2 Bluetooth needs a second or third try getting to connect but I don't use it regularly as it doesn't work on my driver (an electric Smart ForTwo) so I just use it occasionally to check our gas Honda.

I *think* I'm using viper (if I've turned it on and configure it correctly) and the sound seems great on the ****ty little factory speaker. Usually the speed is at 900mhz and temp is near 60c but I don't do much more on it than use iHeartRadio through my iPhone or the OTA radio app sometimes google maps.

**edit** Messed with the Viper settings more and found out it wasn't using Viper. Once I figured out what to turn on, I too am getting the audio slowdown and performance issues. No worries here, my Smart ForTwo only has 2 speakers in the vehicle and the default EQ gives good enough sound for my old ears :) **edit**

I still need to put a fan on the unit but overall very satisfied with it as a daily driver
[FYT Android Head Units] usa911g:
I have used this app, it works but the speed very slow, only 200Kbit/s, I don't know why the speed so slow

[MENTION=520205]gtxaspec[/MENTION] I just tried to install v9a3 using SD Card as suggested from a completely blank jan joying rom and it froze trying to enter twrp. I clicked the reset button to boot up and try again and now my unit is stuck on the joying boot screen.... I also can’t install fresh joying rom cause I can’t boot in to flash stock recovery. Is there anything I can do to get past the joying screen? Or flash the stock recovery without being able to boot?

Update: I attempted to boot my unit this morning and it got past the joying logo and now shows a screen that says “Last update not finished! Please update it!” But when I try to update back to stock recovery, it fails signature validation... please help!!
[FYT Android Head Units] surfer63:
You can simply install it from my JET apk.
[FYT Android Head Units] gtxaspec:
i was able to locate the 04_17 rom, and installed it, doing some testing with viper audio...stay tuned.
[FYT Android Head Units] edit:
If you can solve/correct the Joying active media player buttons issues the ROM will be perfect !
[FYT Android Head Units] derekbunch:
Can anybody help me with getting this to but up successfully?
[FYT Android Head Units] Astur_Torque:
new rom from the 17th of April? or an old from 2017?
[FYT Android Head Units] surfer63:
04_17 is April 2017. So a very old one where Viper4Android still worked.
[FYT Android Head Units] Astur_Torque:
Any important improvements since April? or only "castration" so far?
[FYT Android Head Units] KlaverBoer:
Today i've installed V9Alpha3. The installation of the ROM went smooth and easy. No issues at all. All my daily used apps are running fine. The gpsspeedfix is great just like the phone dailer mod. Compared to the official Joying rom this rom runs smooth.

What does the performance mode exactly do in the custom tool? Will it set a fixed high frequency? Or is it still variable but with a higher max frequency? And is it allready possible to change back to the "normal" speed mode. I haven't tried it yet.
[FYT Android Head Units] derekbunch:
Can anybody tell me if there is a way to restore the stock recovery to a unit that is boot looping?
[FYT Android Head Units] lotte67890:
If you read a couple of pages back in this thread, someone mentioned that removing the SD card, have a fresh prepared USB stick connected which contains the extracted stock rom files from joying and then press the hard reset button for three times (there should be a delay in between, I think press only after the first logo appears on the screen) should fix your problem...
[FYT Android Head Units] derekbunch:
Does this work if I still have the custom recovery installed?

Update: scratch that this worked!! Thanks you! [emoji1305]
[FYT Android Head Units] gtxaspec:
Hi I just read your issues installing...did you always use an SD card? Did you try a USB flash drive to install the ROM?
[FYT Android Head Units] gtxaspec:
i've got a test build of the ROM that has viper audio working...i need someone to test aisde from myself...to make sure. performance mode being enabled is a must, and it will need to be a clean install...also, there is no pregenerated dalvik cache so first boot will take a while.

my viper audio testing method (lol):

enable every option in viper audio

set the equalizer to some funky levels that are very recognizable

play music...for a while...

run a ton of other apps in the BG and push some multi-tasking

1 hour with no issues.
[FYT Android Head Units] IG_Vasilich:
[MENTION=520205]gtxaspec[/MENTION]

it seems that you have found the changes between 04_17 and later ROMs and reverted them in your test build?
[FYT Android Head Units] Astur_Torque:
I would like to find out how the radio send text throught canbus to DIS, mine is Opel and I can see some information such as:

[MP3 $currentSong/$totalListofSongs] (When playing music with native app from Joying this number is raising at the time the app is reading the number of songs at boot)

[RADAR] (When I set the back shift)

[FM $frequency] For the radio

[WELCOME!!] When de MCU boots

[VOL $number] When I rise/reduce the volume

I think these strings came from MCU not from the Canbus BOX, those previous variables should come from the MCU, they shouldn't be fixed

Do your units show the same messages or different ones?

Is it possible to decompile files of apk? there are a lot of xml files with Hex content inside "/res "folder, and I would like to find something from here :D

I don't have much idea about android/developing android, but it's better than nothing ;D
[FYT Android Head Units] gtxaspec:
Yes and no. The test build is the framework from 04_17...which runs better than newer builds...and it makes sense. FYT doesn't have a newer sdk than what Intel has provided to them.

So anything after 04_17 is their own home made improvements...where they broke several libraries that relate to mediaserver and various other audio related libraries.

They are bad at modding stock Android. What they are decent at is fixing their own FYT/SYU apps.

Running 04_17 system with the 01_18 SYU apps runs better for me than the complete 01_18 build.

And viper works...great!

Make sense?
[FYT Android Head Units] derekbunch:
I was able to get this rom installed and it’s been great so far!! Thanks for all the help!! I tried to make a call from my head unit today and got an error that said “cannot dial out in current state”. Is this a know issue or am I just doing something wrong?
[FYT Android Head Units] gtxaspec:
Did you pair in the phone app or the Android settings ?
[FYT Android Head Units] surfer63:
Does this also mean that GPS speed is output correctly on that 04-17 ROM?
[FYT Android Head Units] gtxaspec:
Natively or using GPS fix?
[FYT Android Head Units] gtxaspec:
Okay I just did a test and now it's still reported an incorrect increments but it works using lb droids GPS fix
[FYT Android Head Units] surfer63:
Thanks for testing. I had some hopes it might work before FYT started modifying the Android layer.
[FYT Android Head Units] Astur_Torque:
I don't know why they don't release source code of Android without their own apps or any propietary code

It would be great and excelent for community... Even more if their support for this product is over (last one is from January, right?)

But I really don't believe they'll do it :(
[FYT Android Head Units] gtxaspec:
For JY the latest is Jan...for other vendors there is an April 2018 build floating around...I tested it...not better at all.
[FYT Android Head Units] Astur_Torque:
So... they are screwing up the ROM
[FYT Android Head Units] gtxaspec:
Pretty much lol... In that new build I mentioned USB doesn't work. But it could just be that it's targeted to a mod that doesn't have USB...I've seen pictures of some...
[FYT Android Head Units] Astur_Torque:
And if USB doesn't work... how can you update to a fixed ROM xd?... this for users without any knowledge of rooting, etc..

They hired monkeys typing new code or what? hahaha
[FYT Android Head Units] jesmon:
I'd be happy to try out the test build. Were you saying performance mode needs to be enabled for viper to work?
[FYT Android Head Units] gtxaspec:
No, it actually works perfect without it... Performance mode is always good. I'll postva build tonight.
[FYT Android Head Units] Astur_Torque:
Maybe this weekend I'll try this rom

I currently have the Android 5.1 May (lastest 5.1 version) xd

Before formatting... Do you need anything from 5.1 ROM?
[FYT Android Head Units] derekbunch:
I paired through the phone app, my phone wouldn’t show up in the Android Bluetooth settings
[FYT Android Head Units] Astur_Torque:
Comming from May 5.1, what is the order y should install the rom?

Can I install directly from May 2017 to January 2017, and then gtx? or how?
[FYT Android Head Units] dyabolikarl:
Install joying jan rom first

then gtx
[FYT Android Head Units] hardykalyan:
Hello GTX, do you have an update on the alpha version, you want to upload with 2017 framework?

BTW except for audio... your rom rocks...

[FYT Android Head Units] gtxaspec:
clean install. read the first post for info.
[FYT Android Head Units] jesmon:
9a4 installed no problem. Up and running and it all seems just as quick if not quicker than 9a2. I couldn't get viper to work though. Driver installs but I can't activate it. Tried all the individual Bluetooth/headset/phone speaker etc but it didn't process. I tried locking it to Bluetooth but same thing driver status says processing:no not sure what the trick is. Did multiple reboots, uninstalled and reinstalled driver but couldn't work it out. Will have anothet go at it tomorrow. Tried performance mode to make the reinstalling of apps go quicker, that was great so snappy. But chickened out and disabled it from fear of overheating the unit. Thanks. GTX the rom is great.
[FYT Android Head Units] gtxaspec:
Did you grant root ?
[FYT Android Head Units] amadare:
I installed the new version from the link in the most recent posts but the version number in the upper left still says custom4_9. Need a visual update or is the link still pointing to 4.9?
[FYT Android Head Units] jesmon:
Yep I had granted root. I uninstalled again reinstalled rebooted, enabled, rebooted again and it worked! However with this new rom I am getting Bluetooth audio streaming dropouts (with viper disabled) similar to the recent joying rom that was related to google Play services. I will disable google Play services on my way home from work to confirm that is the culprit.

I screwed up . I went into TWRP and got carried away wiping. I wiped internal storage, data and system. Tried to reboot into recovery from there but recovery never came up. I tried to reflash stock firmware but gets errors probably because I don't have the stock recovery. What should I do ? any help would be greatly appreciated.

Tried to attach a picture but its not letting me, basically says

"failed to verify whole-file signature"

"signature verification failed"

Nevermind, problem solved. I'm back up and running. Should I have known I would get it as soon as I asked for help.

So I've spent about 10min searching through this thread and I see multiple people mentioning they can't set the default boot volume. I have this same issue; I go into car settings and set my default boot volume to 26 (I have another control) and on every boot it resets back to the stock value.
[FYT Android Head Units] gtxaspec:
You have to enable the setting, it's an on off switch in that same screen
[FYT Android Head Units] jindraaa:
Hah! ok going to my car to check now.

I'm also having a bit of a time managing the volume with a remote, I have a Fiio RM1 I paired to it, but I guess the remote adjusts another volume slider not the joying one? This would be ok too but It seems to be reset to either max to minimum after a few seconds. It could be the remote.

Edit: Yep, Just had to tick the setting default boot volume lol. I looked at this but for some reason didn't associate it with what I wanted.

Edit 2: The volume just reset back to 16 on me from 26 after waking from sleep I think? It's still 26 and ticked on in car settings.

BTW this rom is amazing. It's obvious a lot of work was put into this and really takes the joying to a new level.

[FYT Android Head Units] surfer63:
After install it didn't work. After reboot (top bar, drag down, drag down again), it did work.

After 4 custom rom installs, I did not think of that anymore. Became an automatism.
[FYT Android Head Units] hidroela:
works after a reboot ?
[FYT Android Head Units] rilerale:
Nice

I just installed it.

No comparison is true original joying, much faster.

Have indeed a problem with sygic car, but this is certainly back to sygic.

Maybe in the future you will be able to make an update option if you install it completely or just update it.

We would be with Poweramp as a music player.

Works well on the car radio, or jet music player.
[FYT Android Head Units] st.trophey:
How can i add custom button mod? JET secton with sofia server mods is not working.
[FYT Android Head Units] surfer63:
I do agree that Poweramp is a good player, but it is NOT free. It is a 15-days trial.

Anything pre-packed in the ROM should NOT be trial, non-free, or otherwise limited by commercial interests.

I mentioned Timber as it is completely free and open-source, but I do not use it.

Personally I use Pulsar as it is my favorite one, but that one has commercial interests as well, just as jet audio, rocket player and a couple of more.

Again: Personally I think that when a ROM is released it should not contain any third party commecrial app. That is not entirely black&white of course as sometimes you really can't prevent it (and after all: Google is a huge commercial player)
[FYT Android Head Units] sanangel:
I agree with you. If someone wants a free application, it can be downloaded from the Play Store on the android phone and transferred to an usb and installed on Joying. If the original idea of a rom is to be as light as possible, it is not necessary to add applications that most users will not use.
