Hi,

Sorry, I haven't posted for too long. I've been developing the next release of the tools, which is in good way. No eta, though.

I also updated the 1st post to give a better overview of this thread, and the 2nd post to suggest using recovery "factory reset" in case of problems and only if it doesn't work to flash the full firmwares (so that if your device's hardware version is more recent than the full firmware available here, you're not stuck with a black screen).

I'll add the latest raiman OTA as well as the 1st full firmware for fengmi 4k pro (jerry) later today. Thanks to jerry full firmware, users who were stuck like me without the ability to install OTA due to an unexpected system partition state can now fully reset their device.

Now let's try to catch up on questions. Due to the number of posts, I'll keep it short, don't take it personally.

I won't promise anything, but what kind of commands would you find useful for home automation ?

I still haven't found a way to power on, though I haven't tested on my fengOs device. Last time I tested, WOL was not supported, and although I'm sure something can be done with bluetooth, I haven't found how. Power plug remains the best solution.

Hi, are you sure you omunted /system before flashing magisk ?

No idea, sorry. I thing I read the same thing happens on PS5 or xbox series x. It might be related to the projector's edid data. As devices like the nvidia shield are working fine, I suppose an update might fix this issue.

Hi,

I've already developped the hdmi rename option. I'll be in the next update. One limitation though, the shortcuts in the launchers won't reflect the change (on android 6, the shortcut name can't be changed dynamically).

It took time, but I finally managed to get a full firmware image.

Just download the jerry full firmware in the 2nd post and flash it as described.

Not that I know of :(. Too bad because it could be a really cool option.

If I remember well, it's something that could be handled in the display profiles option. I'll try to have a look at it for next release.

Yes kodi is supported on your projector.

Added to my todo list :)

For now, premium is only available for devices with google play (which means, for chinese devices, rooted devices with google services installed). I'll try to implement other methods.

I had the same issue, last year when I decided to invest in a nvidia shield. Sorry to read that the compatibility it still not possible.

My 1st idea didn't work, unfortunately. Then I tried another way, which didn't fix it any better. The 3rd try was the one, though :cool:.

Well, this is surprising. Never had this kind of issue. Could you share a screenshot ?

If you root it, you should be able to disable deinterlacing and dnr, which will in turn reduce the input lag by a few 10s of ms.

Yes, di and dnr can only be changed with root privileges. Please give feedback if you take the plunge as the vava users community is pretty silent here.

I know the chessboard can be displayed if your device is set with the wrong resolution (which you obviously didn't do). But I always suspected there could be other reasons as well. Given your description, it sounds like a hardware issue. Did you plug your usb drive on the rear usb port ? If so, perhaps the board holding the hdmi and usb ports got loose and somehow disconnected itself from the main board ?
