[FYT Android Head Units] gtxaspec:
Q / A:

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 [MENTION=2550900]surfer63[/MENTION]'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.

Q: I need to download the stock Joying firmware so I may use your ROM! Where do I get the latest updates?

A: See here: https://drive.google.com/open?id=1nF5Pgn95_WWGk8S2byb8rR5ko0ss5F_S

Q: is there a video where I can see you install the ROM?
