Firmware for MX4VR boards that work? Maybe ATV?

[momom]

I have a 2gb/16gb MXQ Pro 4k, sold as Leelbox, it had an unusable oreo 8.1 on it, I tried to downgrade with a Leelbox 7.1 and bricked it - unbricked with Nand pin short and flashed the mod 6.0 rom, so far so good. None of the firmwares of Leelbox and others brand seem to work, they all brick this MX4VR board and I have to short pins every time and flash the mod rom. The annoying thing is that I can't shut down the box with the mod rom (it heats and has no phisical power on/off button), also it would be nice to have an Android TV rom. Does someone have a usable rom for this board?

If you can't shut down the tv box, then use a extension cord with an on off switch, that's what I do.

If you want to try another rom, this rom might work. This is a MX4VB board firmware which is similar to your board. Even if it boots up wifi may not work, you just have to flash different firmwares to find out. If it doesn't work you'll have to go back to 6.0.
