Just wanted to leave this here in case someone is wondering (as I did) : tested Logitech G933 wireless headphones today with my rooted Zodiac projector (Logitech USB dongle in the USB port) and they work great. Not sure if I'm getting surround sound but they work (muting the projector speakers and sound comes via the headset).

Hi , I see there is a new update to the chinese version. Any changes? 1.3.129 we have a weird issue.

We are using 2 projectors chinese and international as one huge screen with matrox triplehead2go.

All is great but the chinese one has a bit o lag . We are trying to reduce that .

Any ideas except root - we need the warranty
[Android Software Development] AnythingXDA:
Does rooting and switching to Android TV add more than just the measly single User picture setting profile? How can we get more than one modifiable picture profile? Out of the box only the single User profile allows any adjustment? Why is there only one? It is a great inconvenience having to change each setting individually depending on ambient lighting, HDR, etc. The more custom picture profiles the better. I think my LG had like 3 and it would remember settings for any other default mode you modified such as Movie, Game, Monitor, etc.

My A300 overwrites the User profile as soon as any change is made any of the default profiles which effectively are non-modifiable. Horrible... I like to use Monitor mode with my computer but I can't change anything, not even the brightness without the projector jumping out of the monitor profile and back to User which can not be made to appear as sharp as Monitor. So it is either User mode with a comfortable image or a sharp image, facilitating the reading of small text via Monitor mode sans any adjustability. What gives with the competent hardware but dumptruck picture settings menu? Can anyone fix this or is the picture adjustment menu independent of launcher menu and rooting?
[Android Software Development] spocky12:
No it's not possible to update from 6.0 to 8.1 : hardware is different and even partition layout is not the same (Android 8 has the vendor partition apart). And we don't have any international model firmware to begin with.

You probably lost the file properties during the copy. It happened to me once on a smartphone too.

You can only access it when you're on a hdmi channel, not from the Android launcher itself. But reading your posts on another forum, I guess you've already found it.

I couldn't get Amazon to work either. A user mentioned somewhere in this thread that after contacting their support, they said the app was purposefully blocked on projectors... A confirmation it's blocked on another projector brand would be great. Also if it works on a Xiaomi TV, that could help us finding a workaround.

Concerning the Chromecast app, it requires a special approval from Google to work. During my tests, only YouTube detected it but then it wasn't able to connect. That's why I didn't include it. If somebody somewhere has a workaround I'll gladly add it back.

Last time I checked (on a previous firmware), I could pair my Bluetooth headset (parrot zik 2) with no problem.

Is the engineering menu not functional? I believe I've also seen this parameter in the Xiaomi settings somewhere.

Without root, my patch to reduce the input lag won't work, unfortunately, so the lowest input lag you can obtain will be with game or monitor mode (don't remember which one, I've mentioned it in a previous post).

Concerning the new update, I can't tell you right now as I'm on holidays, I'll check when I get back home.
[Android Software Development] spocky12:
Well it'll probably require a lot of work, but I believe I can come up with my own picture profile system on rooted rainman/batman devices. Can't give any eta on this, though.
[Android Software Development] Vsk8:
Hi. I didn't find anything about engineering menu not functional, is it an apk or how to get it? I searched everything in settings but I found nothing.

Is it possible to unroot? Maybe using a full system rom and flash drom usb?

In case of waranty issues.

Root seems easy enough to do with your help and youtube
[Android Software Development] idefix_sin:
Thanks for the reply.

Amazon Prime

I found this post stating that Prime works on the Mi box. Might be a lead (tried to load the same version via aptoide TV but with no luck) :

https://www.reddit.com/r/MiBox/comments/9bdgbh/prime_video_not_working/

And looking at this video, it looks like is does work on Mi TV Pro as well.

https://youtu.be/u-go-UbfZd0

Old Mi TV's however do not work and require a different apk from the looks of it

https://youtu.be/zmLakj7ne-Y

Tried the current version as the one from the video is not available anymore and it did not work.

One user mentioned that the Saturday version worked but it also crashed for me.

Unfortunately no easy solution it seems.

Other suggestion: could you add a issues/not yet working section to the first post to highlight open issues with the projector sw (like Amazon prime, chromecast etc)? This might make it easier for people to spot where they can contribute or someone with a solution might stumble over it there to provide ideas etc.

Mijia Youth Projector

Hey

What a great thread. Thanks to everyone who goes to the effort for this stuff. The news makes it out like everyone is an asshole. Not true :)

I recently purchased a Xiaomi Youth Projector from Shanghai whilst over there for work, and it's bloody amazing. I don't even mind the Chinese OS as most of it is in English and I can get most apps that I need to work. The only Apps that don't work that would make it that much better are Netflix and Google Play. Do you know if there's a particular Netflix APK I could use? I can currently open the app and browse the menu, but when I press play the video freezes and a message pops up with an error (I don't have the message right now).

I'd be open to rooting the device if you guys think this will work with my projector model.\

Thanks for your help.
[Android Software Development] spocky12:
Great findings! I'll have a further look at it when I come back home.

Thanks for your other suggestion, I've edited the second post to add known issues.

An old version of Netflix requiring a mouse is supposed to work (mentioned a few times in this thread), but I haven't been able to put my hands on it. But, rooted or not, you'll probably never have more than SD on it.

Concerning Google play, using the tutorial on the first post, you'll be able to use it with no problem.
[Android Software Development] botelucian:
Thanks for the hard work.

We succesfully rooted the device.

But still has a bit of lag compared to batman.

I turned of noise reduction and athe other thing using the long press back key.

Is there anything else to do ?

Also using monitor mode as its the best for us. User mode has more lag.

O the other one the International veraion can i do something to ad lag? Noise reduction is high . Anything else?

---------- Post added at 07:59 PM ---------- Previous post was at 07:54 PM ----------

We didn't do anything else except root + your app.

We just need hdmi input.

Will freezing apss help? Or changing launcher?

Error with manual installation of Magisk module

Thanks for your amazing work [MENTION=848496]spocky12[/MENTION]!

I managed to root my batman projector. I also install the google apps and Magisk.

I can install Magisk module from the Download section. But when I try to manually install a module by clicking on the "plus" yellow button of the Modules section, I get a notification saying "No application can do this action" and nothing happens. I checked the logs with adb logcat but no error is output when I click on the "plus".

Does anybody get the same behaviour ?
[Android Software Development] botelucian:
This is our main goal.

Things are close. But now another problem is the international version. It doesn't keep picture settings in the user mode. They have no efect on the hdmi input. They work in the menu but not on playback

[Android Software Development] nyunyu:
Hi guys, sorry if I sound noob but can anyone help me with rooting the Mijia Youth projector?

I can't find the option where I could turn on debugging on this unit. I saw some users managed to root theirs perhaps if I could get anyone to help/guide me?

I spam clicked the android version number and it shows sequence number (in chinese): 00073/472. Then I tried to adb connect IP:5555 and it came back with "unable to connect to IP:5555" (adb connect IP only also gave same reply)

I can't make the Root

I followed all the steps described in post # 2 to root my Xiaomi Mijia Projector Youth Edition MJJGTYDS02FM, but when I try to install Magisk 19.3 it gives me error 127 and does not install it. Miui TV version 1.3.97 (stable) is installed on the projector. I tried also with version 1.3.123 (beta), no result I can't get root.

Can anyone help me find the solution?

---------- Post added at 08:47 AM ---------- Previous post was at 08:38 AM ----------

I had a chat with the Chinese Xiaomi site and they advised me to buy these glasses for the projector in question: FENGMI Model: FM3DG2 sending me the link to this website:

Have any of you tried them?

Do they work?
[Android Software Development] nyunyu:
Just want to say I managed to have my Mijia Youth rooted as per the guide. Had to rushed out to my local computer store buying an usb hub for installing magisk, other than that, everything went smooth.

Thank you for your work. Much appreciated.
[Android Software Development] MustosClan:
I also used a USB hub (to be able to use the mouse) but it still didn't work. What version of MIUI had you installed at the time of the Root?
[Android Software Development] nyunyu:
I didn't recalled the MIUI version but I also hit a snag when trying to root using both mouse and usb stick connected to the hub. What I did was

- first plug in the usb stick at the back of the projector, adb reboot to get on twrp running

- go to mount, uncheck/unmount usb drive

- unplug usb stick, plug in hub with mouse and wait until mouse cursor loads up on the screen

- plug in usb stick into the hub

- mount the usb drive again

For some reason, I can't boot into twrp with usb stick connected to the hub, it needed to plug in directly to the projector.
[Android Software Development] MustosClan:
I tried how you recommended me, it doesn't work!

I receive these error messages:

I'm using this version of netflix and while it has some quirks it does loads stream fine. Don't think 4K works though but for me it is usable.

Mind you, to pause a stream, press and hold menu until projector options pops up.

To resume, hit back and any of the left right dpad button, it will fast forward/backward depends on which dpad you press but it'll resume for sure.

[MENTION=848496]spocky12[/MENTION], is it possible to implement xposed framework in this projector? Some apps (Astro Go in my case) is detected root when logged in and unable to use. Some users suggested installing xposed and rootcloak which I'm not sure they're even supported in this projector. I know one can add xposed from Magisk module but hesitate to do so as I'm not sure if its going to break the whole thing.

Worth to mention that I tried hide root option in magisk and it didn't work for this app.

Hi,

I just installed everything and it works perfectly :) It's nice to don't have anymore all those chineese stuff.

Anyway, I updated MyCanal App (a french TV app) and it doesn't load anymore... It tells :

" This app won't work properly unless you allow Google Play services' request to acess the following:

• Phone

To continue, open settings, then permissions, and allow all listed items."

But when I do that, Nothing happens when I hit the permission button...

Any idea how to fix this problem ?

Thank you

RS-232 or Serial Command

Hello everyone!

I've been following this thread since the beginning as the UST projector tools came in quite handy (new update fied a lots of issues though).

I'm now confronted with a different issue : I'd like to be able to execute serial or CEC command to turn on and off. We'll be using two of these projectors in our museum, and we'd like to avoid to go through the trouble of setting them on and off everyday.

We're using Brightsign players which are able to send simple control through HDMI (Brightcontrol display on and off), though no success at all (even if the settings of the device has a point about control through HDMI). I also know the the Batman had a USB to RS-232 adapter (though no codes or strings mentioned).

Any help would be appreciated, thanks in advance.

Hi guys.

Received a new Xiaomi 4K projector earlier this week and I am trying to have it rooted.

However I'm not able to get past the "Enable ADB debugging in settings / developer options".

I've tried tapping the Android version 7+ times, but it still does not want to give the the developer settings, and therefore the projector refuses connection to the ADB.

Is there any way around this?

And on a side note, probably a bit off topic;

My projector is connected to my media computer. Just bought a brand new graphics card to cope with the 4K resolution, as my old one couldn't go past 1080p.

New graphics card is a Gigabyte GeForce RTX 2060 OC 6G Rev 2.0, with DisplayPort 1.4 and HDMI 2.0.

However, I'm not able to push the signal to 2160p@60Hz. Update frequency is stuck at 30Hz, both on DP-out and HDMI-out. Anyone had the same problems?

Projector specs:

MIUI: 1.3.105

Android: 6.0.1

Update:

Managed to get it rooted. Used a .apk to access debug menu.

The 30Hz problem is still an issue.
[Android Software Development] Y_B_A_FOOL:
I have the same issue, the projector will not run 4k60 even with a custom resolution., the max it allows is 4k30. My computer detects its 3d compatible but it says it's not HDR compatible. Does anyone have any input of the issue? Thanks
[Android Software Development] spocky12:
Back from vacation, I'll do my best to answer most questions I can, sorry if I missed one or two.

I understand that your international device has lower input lag compared to the batman, is that right ? Unfortunately, I have never used the international model, and as long as we can't root it, we're very limited on what we can do. I don't know how you can match both input lags.

Sorry, I've never had this issue.

You'll need to restore your kernel ("boot" partition) in TWRP beforehand, and then reinstall magisk. I've updated the FAQ to mention it.

I can confirm Hdmi ARC feature is limited to HDMI3 on rainman/batman. I don't know for the Youth edition though.

Did you mount System partition in TWRP before installing Magisk ?

Thanks for this precious information, I've been able to fix Netflix with Google Apps installed. I just need a few days more before releasing it.

Beware though, the version you're linking to seems to be infected with a malware. I don't recommend installing it.

I won't have time to try to implement xposed unfortunately. As for the magisk module, just make a backup to boot and system partitions in twrp before testing, you won't risk much.

Yes, the "permissions" in settings don't work, I suppose it's a limitation from Xiaomi, but I haven't has time to check. I've been able to use old versions of this app in the past

.

That can't be done, but a workaround is to enable the "manual google play fix" in the mi proj tools. It will disable the volume/shutdown/recent apps UI. When you need to power off your device, I'll have to disable the fix, to have the shutdown popup.

I know that this device can be powered on by HDMI : I've seen it powering on a few times already, but I could find out in which exact situation (had a chromecast and a tv box plugged it through my yamaha amp), nor reproduce it.

If you find ore about it, don't hesitate to share your experience.

Make sure to enable HDMI 2.0 in the settings for this HDMI input, else I believe i won't work as expected.

Projector Long Boot Times

Is anyone else experiencing long startup times when turning their projector on?

Have rooted the device following the instructions here a while back now (Batman) and in the last month the projector takes 5+ minutes to turn on. Sometimes I have to reboot just to get the screen to turn on. The problem seems to be the image, as I can hear audio coming though the background when I blindly load up a TV show or YouTube....but actual video takes ages to load up. The "mi" logo and boot screen also don't appear anymore either.

Any help is much appreciated.
[Android Software Development] spocky12:
Open an HDMI input as you would normally do to watch a program and use the menu button to open the settings related to this HDMI input. There you'll fine settings to enable HDMI 2.0 as well as some CEC settings. Contrary to the display settings that are universal, these settings are per input.

Never had this kind of issue. Installing the Google Apps increases the boot time for maybe 10 seconds, not minutes. I unfortunately suspect a hardware issue, like a bad capacitor (if no light at all comes out of your device for a few minutes, this is probably not software : the logo and boot screen are displayed before android is even loaded).

After these few minutes when the image appears, what happens when you reboot your device ? Does it take some time to display the image again, or do the subsequent reboots happen normally ?

To be really sure it's not software, try to reinstall everything from scratch, flashing the full firmware in post #2, but honestly I don't expect any improvement :(
[Android Software Development] stuismad:
Light comes out but it's a 'blank' screen on boot. no Mi logo or the blue load screen. Used to load no problem but now it's just slow to load an actual image. if it gets worse I'll try and reload the full firmware again and going the whole process again from scratch.
[Android Software Development] Dr1ve:
Great success! I didn't even know there was a menu there!

1: Select the HDMI-source

2: Press the menu button to the right of the back-button on the remote

3: Go to "Playback settings"

4: Select HDMI 2.0 and select "on"

YCbCr420 color mode works fine.

Couple of quick questions

Hi,

First of all, thanks a lot to [MENTION=848496]spocky12[/MENTION] for this wonderful toolset. I have rooted several devices in the past but this is really a no-brainer! Good job!

I have a Mijia Youth Projector and there is a couple of issues that I would like to solve:

1) KODI 18 does not work. 17.2 does without problems (which is great) but I am just curious about why newer versions do not even start.

2) If I select Bluetooth as output for the audio, the YouTube app is not able to play videos. This does not happen with any other app and I get sound through Bluetooth speakers (although the volume is really low so a good amplifier is needed). Any idea why?

Thanks a lot in advance and keep the good work!
