This is an excellent thread and helped me to get more familiar with my Wemax 1080p. (Chinese). A few questions:

1) Rooting instruction say that a mouse is required? My projector only has one USB port (used by the stick to root), so how to connect the mouse?

2) The benefit of rooting the device seems less clear to me. What's the main advantage?

3) Is there any way that I permanently change the UI at launch?

4) Stupid question, but how can I turn off the projector? I currently do by unplugging, but assume there must be another way?

5) I installed one APP through Aptiode (Virtualhere server). It has an option to "start app at launch". Unfortunately, this doesn't seem to work and I need to manually start it at launch It's not an issue of the app as it does work on my Nvidia Shield TV. What could be the reason?

6) Are there hopes to see an Android TV upgrade from 6 to 8?

7) Some apps seem to work, but not flawless. Could this be due to android 6 vs 8?

8) Anyone tried using Moonlight or Steamlink? Any experiemces to share?

9) I cannot connect an Xbox controller via bluetooth. Any idea why this is the case and any hope this may work eventually in the future?

Hi Spocky,

did you manage to have a look at the playstore update issue yet? Would be great if a fix or a update blocker could be implemented.

On a different note:

1. I still have the wifi issues. More or less after every reboot (power cable plugged) the wifi connection is gone. When I try and access the previously saved network it gives me a password error each and every time (although the password is correct and worked before). Only connecting it via WPS and code works. :( Annoying and no idea what the issue could be. The projector is more or less stock including root and google tools.

2. Youtube suddenly stopped working. It will show the videos but when I start one it will show a still image, audio for a few seconds after which the audio stops as well and only the still image remains. Happens to all videos. Tried resetting the app, clearing data/cache, reinstalling and installing earlier versions of the youtube app but no success so far. Could be that one of the google services which updated, messed this up? Will try and remove all updates from these as well and see if that helps.

Thanks !

Hi guys,

I'm using the international 02 version of the Xiaomi UST (NON 4K mjjgyy02fm)

Unfortunately I didn't recognize the missing features compared to the Chinese version. Therefore I would like to know:

1) is it possible to root the international version so that I can also boot directly from a different input (e.g. fire TV stick on HDMI 1)

2) it's very disappointing that the international version doesn't offer HDR. Is this software related or caused by the different hardware of the international version ?

3) if it's software related: Might it be possible to change the android 8 system to the Chinese one ?

Best regards

PB with YouTube has been solved after simply rebooting

Sorry
[Android Software Development] stevepalmer1977:
went head and rooted the device. I hope I got it right and installed all in the right places. Not sure this is sufficient evidence, but it now shows as rooted and I do have a Magisk app installed now.

Unfortunately, I cannot install ATV Launcher. I went to "Applications - Install 3rd party apps" and then selected "ATV Launcher free 0.11", but it just closes and is back to the menu where I can select "Install 3rd party apps". No error message at all, just not working.

Also, Youtube TV does not install either. When clicking it, it allows me to select "install" and download completes at 100%. It then asks me again to "install". Then I see an error message "App not installed. Please check the device and network status again, -113).

Thoughts? Thanks a lot in advance!

Wemax A300 noise / Bass speaker / Plastic case

Has anyone noticed the wemax A300 making some noise during especially explosions, storms ?

My projector is making some noise from the bass speaker I think under the box where holes let the basses go out , and I also think its the plastic case which is vibrating doing like 'clic clic clic ' , very annoying. If I put my finger in the left hole it can make things even worse

Fyi: I'm not talking on the high frequency laser or wheel colour noise this time ...

Anyone who opened the box and able to fix that ?

Thanks all

Thanks for your quick reply. Is Youtube TV working for you?
[Android Software Development] stevepalmer1977:
I installed Youtube from the Google Store instead and it seems to be working. Not sure this approach has some disadvantage?

Things seem to be good now. Just two questions remaining:

1) I succeeded to pair two bluetooth controllers. Unfortunately, I cannot connect them again. They still show in the settings, but somehow they cannot connect. Do I need to somewhere enable bluetooth? I'd like to avoid that I need to pair them after each reboot.

2) How to switch between ATV and Leanback launcher? Which one is closest to stock Google TV?
[Android Software Development] idefix_sin:
Update to my own post :D

I figured out what causes the YouTube issue and this is. An interesting one.

When my Bluetooth headphones are connected, YouTube fails to work as described above. As soon as I disconnect them all works fine again. To the extend that I open Youtube with BT headphones connected, start a stream, fails. Switch the headphone power off without exiting youtube. Press play again and it is working. Switch the headphones on again. Stops working. Can start a stream with headphones off and it works, switch the headphones on during playback and the stream hangs.... Wow....

Hello how save the original rom and how install the new there are an tuto for novice this is for wemax A300 projector sorry for my English I'm French :laugh:
[Android Software Development] stevepalmer1977:
Excellent, thanks a lot!

All seems to be working very well. Just my XBox controllers keep making trouble. In fact, since rooting the Wemax, they are well detected and seem to work. So, the key layout seems to be available once rooted? The primary issue is that they pair well, but then do not connect again after restart. I need to unpair them and pair them. Are you saying this is a known issue or that this is something you don't experience?
[Android Software Development] spocky12:
You need to install the MiProjectivy Tools app, which is not (yet) available on Google Play. So you'll have to install it from USB, which requires to "Allow unknown sources". Once installed, activate the Accessibility service from the android settings. Then you can selected which input to automatically start on boon in the "input settings" menu

The only bluetooth devices I've paired are a logitech keyboard and my Parrot Zik 2.0. Both work fine when I use them (very) occasionnaly. I suspected your remote issue was related to the layout mapping being absent, but if it works at least once, this is not the issue.

i think i'm stuck after a factory reset.

my mijia was rooted and worked perfectly without chinese bloatware.

2 days ago started seeing the "error!" msg (missing launcher ?), it was an update failing to install i think.

i did the update and then after a restart i got a black screen

if i plug an usb pendrive, i get the corresponding menu but can't browse the pendrive.

i tried several factory reset which is accessible in usb menu without success

and i can't connect using adb

do you know what else could be done ?

Just a couple of quick questions... I have a Xiaomi Youth Edition projector and the internal memory is a bit sort. Is it possible to use a USB for the storage of files in Kodi, PopcornTime, etc? Alternatively, is it possible to delete some of the Chinese stock apps without affecting the system?

Thanks a lot in advance!

[Android Software Development] Homar80:
Hi can you tell me something more about time off your "slow boot issue". I just updated my Mijia to build 9.11.6.624 and it's still Miui TV version 1.3.105 (stable). After that I just updated magisk from 19.3 to 20.1 and I saw long boot as well. Now I back to magisk 19.3 and my problem gone,but I have got a backup Chinese version software and backup Spocky12 software. I just go to TWRP and choose a backup option for Spocky12 version long boot disappear. Previous boot time was something about 30 seconds after update to new version software and magisk something about 50 seconds,now I have got that same time witch a version 9.11.6.624 about 30 seconds with magisk 19.3.

[Android Software Development] zythoun:
Hello,

I don't think this is the same problem, there is known issue with the batman version that is probably because of the video cable. My boot use to take a lot of time (10 minutes or so) and once hot, the image was good. But from now on, no image at all. And no access to the TWRP either.

[Android Software Development] spocky12:
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.

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 :D

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 :p

usb key or drive is same for me ;)

[Android Software Development] lpritchard:
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!

when you have i idea than write me :)
[Android Software Development] spocky12:
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.
[Android Software Development] spocky12:
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 ?

is there any one who can make a to do list for Fengmi L176FCN in order to help me and other people?

My goal is to reove chinese apps and install rom with google/app store and is possible aptoide tv.

Thank you very much.
[Android Software Development] spocky12:
The steps are the same for any compatible devices (your device codename is "batman"): just follow the steps in the "Installation steps" section of the 1st post to install the google services. The 1st installation step will redirect you to the rooting tutorial in the second post, where you just have to follow the "Easy Method". Everything should be detailed enough but if you think anything is unclear, don't hesitate to ask.
