That worked for getting me back to a stock image. Was able to root it (wifi-ADB method).
But, the custom app doesn't seem to be installing TWRP (or I am not able to boot to recovery)... it says it installed, verify says it's there, but both reboot options from the app just have the system reboot normally (not to recovery). Same thing it was doing when I tried to re-install the rom image from the "broken" install.
Both the custom apk and the rom files I downloaded from the first post. I do remember having issues when I went to install this originally... but I don't remember what special thing I had to do to get it to go.
Use apps to enable ADB over wifi and obtain IP address
Use the .bat script in the first post to get root (do not use the SuperSu method listed in another thread! It breaks something somewhere). Set Superuser to "always grant" (as for some reason I've never been able to allow root access via prompt on this head unit). Launch custom and install custom recovery.
Make USB stick with GTX files. Install rom via the three reset method.
Wait patiently and eventually it will start to update.
Pull the USB stick once the "android" boot logo comes up!
Translation: RTFM... to include how to obtain root!
Edit- still back to square one with google play services crashing things. At least I've been able to use the custom app within the gtx rom to install the custom bootloader and then use the three reset method to reinstall said rom. Seeing if there's a workaround... as it (and anything dependant on it) fails within 5 minutes or so of the intial bootup (not a recent version issue, not updating doesn't help my cause). Worst case, at least I got my $20 out of the head unit.
Edit2- Fixed the original issue by swapping the OpenGapps file for the latest pico file for x86 (renamed file, too lazy to edit the TWRP script )... so far, so good.
Ok, managed to install the latest 6.0 pico x86 opengapps, but the problem persists.
Flashed the pico file alone, with twrp. Didn't work.
Flashed the whole ROM file with the new pico opengapps inside. Didn't work.

For FYT SoM (5009/6011/6021/6022/6023) based JOYING / Intel SoFIA units ONLY!
Hello, here is a custom rom based on the SYU Stock Build [sofia3gr_car_64-userdebug 6.0.1 MMB29M eng.bsp.20180110.181524 release-keys]
Your Head Unit MUST ALREADY BE ROOTED! You must be able to obtain Super User access within Android!
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.
Why this ROM? Simple answer: It's makes your Head Unit faster than running the stock ROM's, has updated Google Apps, and has the bloat removed! It's pre-rooted also!
Step 1: Unzip the contents to the root of your USB flash drive on your computer, then plug the flash drive into the Joying unit via USB.
Step 2. Use the Android helper application "custom" to install. Download from link below, either on the Head Unit itself, OR on PC and transfer using ADB. Once installed, open the program, and grant superuser privileges when prompted, you'll be presented with screen as here:
Step 3: Click INSTALL CUSTOM. Wait for output to say recovery successfully installed!
If you wish to preserve your /data, AKA dirty-flash, click on "Do not wipe data" at this point to prevent your data partition from being wiped.
ALL EXISTING DATA ON UNIT WILL BE ERASED. THIS IS A CLEAN INSTALLATION!
Step 4: click REBOOT TO INSTALL GTX ROM - Your Joying unit will reboot, and installation will automatically proceed through TWRP.
(NOTE! The ROM automatically re-installs stock recovery during installation, so if something goes wrong, you can always restore to the original JOYING firmware.)
RESTORE STOCK - Restores the original stock recovery
INSTALL CUSTOM - Installs superdave's custom recovery (needed to install this ROM)
VERIFY RECOVERY - tells you which recovery you have installed
(all options on this menu work only if you have custom recovery installed)
"Do Not Wipe Data" Switch - enable this to prevent your /data partition from being wiped when installing the ROM. (Your results may vary. Works for me!)
REBOOT TO TWRP - Reboots to TWRP home screen allowing you to do things
INSTALL GTX ROM- installs joying_gtx stock rom from installation media
Exit - exit custom

Q: Do I need to worry about what MCU version I have before I use your rom?
A: Maybe, GTX ROM doesn't touch the MCU, which shouldn't be re-flashed with each install anyway as it usually doesn't change. Whatever MCU version you have, this ROM will work for you, as long as you have an FYT based SoM unit. If you encounter errors, you might need to change the "ro.build.fytmanufacturer" property in /system/app/fyt.prop to match whatever your unit ORIGINALLY came with.
Q: I have a RK3066/RK3188/PX3/PX5 based head unit. Will this ROM work for me?
A: NO! This ROM ONLY works on FYT based head units. This means all Joying Intel units, as well as some from other brands.
Q: I like Live Wallpapers. How do I enable them?
A: Use the built in terminal. type su and hit enter. You now have root. then type in:
cp -R /system/vendor/oem/LiveWall* /system/app
hit enter again, then reboot!
Q: I don't want to use this ROM anymore, what do i do?
A: Use the helper application, custom, open the program, and click RESTORE STOCK. This will restore the STOCK RECOVERY. Go on Joying's website [link], download the firmware of your choice, and follow their instructions.
Q: Can I use google voice to make hands free calls?
A: You sure can. Use the "Voice Search" app to dial a number using your voice, once at the Google App screen, click on the hamburger menu, and then select GV CallHandler 4 Joying. Make sure your unit is set to a DPI of at least 161dpi or greater, and then clear data on the google app. After you reboot, you should be able to make calls.
Q: How do I view my front camera?
A: If you are using the analog RCA video input, on the back of the unit, you can use the RIGHT CAMERA app to view. Note, than unlike the AUX program, this one will NOT mute the system audio.
Q: How can I fix my GPS speed to calculate 1/kmh or 1/mph steps instead of the default 4 steps?
A: Go to XPOSED INSTALLER, and enable the GPSSpeedFix module. Reboot, and the steps will be fixed.
Q: How can I enable different DPI settings for each application?
A: Go to XPOSED INSTALLER, and enable the App Settings module. Exit the installer, and open the App Settings to make your adjustments. Reboot, and your changes will be visible.
Q: This ROM is fast, but I want more speed, what do I do?
A: Add a fan to your unit, preferably a FAN + Heatsink. Then download an app like SetCPU to lock your CPU to MAX speed. Be careful.
Q: How do I re-assign the hard keys on my unit? Joying says that DVD and EJECT don't work! Is this a lie?
A: Yes! There is a way to re-assign keys, and the DVD and EJECT keys do actually work, the software that comes with the unit is not very good. Check @surfer63's XSofiaTweaker thread for more info on how this works.
Q: I want to send and receive my text messages on my Joying unit...is this possible?
A: Sure! Use third party app like Pulse, or Pushbullet. Works like a charm. I personally use Pulse, it's got the look and feel of a stock SMS app.
Q: Installing the Joying Factory Rom takes like an hour...multiple reboots, then it starts over, then it reboots, then it optimizes apps, then it starts over, again. jeez. How long does your ROM take to install?
A: Installation is less than 4 minutes. First boot is timed at one minute 53 seconds, and there are no crashes or reboots. It just works.
Q: Xposed says there is an update available! Is it safe to update Xposed?
A: NO! Do NOT update Xposed, it will make your unit non-functional! Just say NO!
Q: Am I able to "upgrade" from an earlier version of the ROM to a newer without loosing my data and apps?
A: Yes, read the first post on what option to select in custom. Many others and I have tested, and it works for almost all people, still there is a chance that it could not work.
So with lots of testing, the GTX JY ROM will be moving to a v10 STABLE release very soon. v9 should be released within the next few days, with some V9 point releases in between for bug fixes. Thanks to everyone who has used, tested, broken, and is enjoying their head units! Please send lots of feedback to help move to V10 stable for more to enjoy.
