So, got anyones problems solved by opening the device? Just ordered one yesterday and now found this because I wondered if I could root it.

Does anyone have this problem after some weeks or months? Should I try to step back from my order?

Cheers.

MiProjecTivy Tools is just declared as an alternative launcher, as a failsafe option so that people who disable stock launcher without installing another one don't need to reflash full firmware. It doesn't force anything, so if you have ATV also installed, using the home button will ask you which launcher you want. In this popup, if you select ATV and the button "use as default launcher" (or something like this), it should no be bothering you again with the Mi ProjecTivy tools. Hope that makes sense.

As I now have a 2k black brick

Not sure I understand well. You're saying that after enabling the MiProjecTivy Tools Accessibility firmware, you got the checkerboard screen ? Could you please give me more details ? What is your device ?
Concerning your issue, just let your device totally boot to android and use the shutdown remote control button to power it off. Then download the full firmware for your device, extract it to a usb device and boot your projector as required to start stock recovery (remember : it will only work if your properly shut it down before) : the recovery will detect it and automatically flash it with no input needed on your side.

You don't need to mount usb, "udisk" is automatically mounted (as long as you don't unplug/replug it) and will contain the contents of your usb device.

It seems to only affect mijia 4k users (not all of them). Opening the device has fixed the issue for a few users who reported here. Seems it didn't work for all people though.

"usb key" = "usb thumb drive" in french
If you don't touch your usb device (ie : don't unplug / replug it, or try to mount/unmount usb or udisk ), udisk should indeed list what is available on your usb drive. Udisk is mounted really early in the system boot process, in order to read custom recovery or firmware files, so if you could boot twrp (meaning it could read twrp in udisk), I can't see a reason you can't find your other files as well.

Well this is a known issue and is "by design" on 4k devices (batman). But I don't know if it varies among devices or if they all produce the same noise. Usually, setting your device brightness to "highlight" instead of "movie" will decrease this high pitch noise (at the expense of producing more heat, thus ramping the fans up). Or you could just patient until you get older and you don't hear very high frequencies anymore

Managed to successfully install this today on my new 4k projector! Thank you so much for such awesome software.

A few things -

- It may be worth including in the root tutorial how to enable developer mode/ USB Debugging on the batman projector - you have to click "device name" 5 times in the about section of the settings menu and then go back to main settings menu and select "account & security" then enable ABD debugging. I've noticed every reboot this goes to the off state - which will prevent users from using accessing it via ADB.

- May also be worth mentioning that you need to use a USB dongle to be able to access the USB stick and mouse at the same time - the batman projector only has one USB port so unless you have a wireless/bluetooth mouse - you will need this

- I am confused as to how I can set my projector to 4K Resolution - which settings menu am I to do this from?

- Is it possible get the old interface back without removing my Google interface?

- Any updates on getting the Chromecast function working?

Thank you!

Hi,
Thanks for your message.

- help on accessing dev options is already described twice in the 1st ("to enable "developer options", see here") and 2nd post ("Enable USB debugging in Android settings / developer options"). Xiaomi's framework automatically disable it on each reboot, but if your device is rooted and you install "build props overrides", it will stick.
- batman and rainman have 2 usb ports, one on the rear, one on the right side.
- don't bother forcing UI to 4k, more details here
- yes, just freeze "leanback launcher" and unfreeze "stock launcher"
- this depends on Google, so we probably won't have it anytime soon.

Checkerboard
I am using a wemax Chinese version. Rooted revice and tried to plug on Xbox one x and changed windows resolution to 4K worked ok but then installed google play services to get rid of stock Chinese menus, this resulted in double images and artifacts being show on screen like a 3D image wide by side. Can I flash with rom file without the need for accessing the bootloader menus as nothing works on the unit. Always giving me checkerboard when booting up always now.

Concerning the fix, I've already answered your question above.

I also need a few more data :
- What is your exact device model (wemax a300 or previous wemax versions ?)
- How did you change windows resolution to 4k ? Using MiProjecTivy Tools ?
- Did you enable the MiProjectivy Tools accessibility service ?
- You said that after installing google play service, it "resulted in double images". Could you please tell me exactly what you did ? When did it display these "double images" ? Just after installation ? After a reboot ? After you got into Android Tv settings and try to change the device resolution in the menu ?
