[HELP] Vivibright F30UP projector - atvXv4 can't use remote

[SirKing]

Hello,
I had for Christmas a Vivibright F30UP Projector that was running Android 6.0.1 and I wanted to upgrade to Android 9.0 or the latest version, so I downloaded A, - tvXperience V4 Multi Wifi and I flash it on the projector with USB Burning Tool but the problem is that I get stuck in the setup menu because the remote control and the projector controls don't work on this version. Also, my computer doesn't detect it in USB Burning Tool anymore, so it's impossible to reset it to install another version, could someone please help me?

...I get stuck in the setup menu because the remote control and the projector controls don't work...

Use (air) mouse or keyboard to get through setup...

Perfect, thanks I managed to do the setup but now I can't control the Android version neither with the remote control, nor with the projector buttons nor with an Android tv remote application. How can I do it?

Copy this remote files to vendor/etc/ folder.

Okay, I tried but I don't know how to do it, if I connect via ssh or ftp when I try to delete or overwrite the old file, the system answers "Read-only file system" even if I'm root. Can you explain to me how I can do this?

Click the lock symbol, to allow Read/Write on the system...

Nice, I transferred the files to the right place, I restarted the projector, but it still doesn't work.

Those remote files are from stock Android 9 firmware [MEGA.nz], check if the files permissions are (0644) set right.
