Man! Could you please dump and share your rom with us? It should be located in /dev/block/backup (that's the file itself). I was able to access mine (The Chinese rom version) with MiXplorer. Thanks!
[Android Software Development] IrishKevin:
I don't have the global version as it was much cheaper to order the Chinese one, was just letting spocky know that it was out there. Apologies for misleading you :(

Hi I just reverted to version 2.17 because v3 doesn't work for me. The lag reduction was not aplying. If i had to go in the ap and disable the setings and go back to hdmi 1 I lose the settings and get lag.

With 2.17 I get lower lag using back buton long press. But i've lost the shutdown . When i press off button It just goes black but not turning off. Please help
[Android Software Development] spocky12:
The issue is that in a "monitor" display modes, xiaomi resets the options that my tools change to lower the input lag. This code is executed each time you switch input mode. So my tools (in "android source") changes the settings for input lag, and when you exit and go back to the "hdmi source" you were, these settings are overriden by the stock display settings manager. The only fix I can do is change these parameters directly within the hdmi input source app. I'll add back the long press back behavior in the next release to enable it.

Something weird is going on. I have green sparkling dots(Conway's Game of Life in 4k :laugh:) in dark areas when i increas the Framerate to 45Hz@4k or above. I tried 4 different HDMI Cables (2 are Premium certified) . Either my Projector arrived broken or my GPU(GTX1070 ti) has a problem. Has anyone experienced something similar? I will try to find an other HDMI Source.

what length of HDMI cable I have similarly on a 3m cable, when I take 2.5m it is good, the problem occurs at a frequency of 60 Hz. I changed the color issue in the NVIDIA panel from RGB to 4.2.2 and 10bit and it's ok, I just don't know how to measure the delay.

Hi can you add in next release option to turn off WiFi and turn on WiFi like Hdmi shortcuts. I just saw a strange things Android OS takes a lots data every month,yes I try to turn off WiFi but after a few seconds is back again. I don't want to forget my WiFi every time then I won't to use my internet connection and after again sing in to my WiFi and give again password. If that will be something easy to do can you check this, please.

Thanks for your hard work.Sorry English is not my native language.

Hi

[MENTION=544045]Spocky[/MENTION] for what is this rom Full rom 1.3.105 (6.0.1.494). Just extract to USB root and start recovery to flash. Is this the same firmeware as the original firmware.

And give it a sounddriver for the fengmi. The sound is sway. the tone becomes light and dark.

Thanks

Edit : for those who have not seen it, the kodi "amlogic fix/workaround" from fritsch for our device has been merged in master source code, so next (18.6) official release will work on our device (but 19.x won't). Thanks @servo386 for helping fixing it !

If your wifi turns on automatically after you turn it off, I suppose it will be the same if I do it from my tools. I'll try to think of a workaround. Concerning the data it takes, you could try 2 things :

- make sure you froze stock apps

- try installing a firewall app

It's a stock batman rom extracted from my own Fengmi. Note that they almost immediately released a 536 version for fengmi and wemax, so we can imagine the stock version was probably not totally stable.

That was first things what I do, freeze stock apps.

Have you recommend any good firewall app?

I'm using my projector like a TV ,Netflix or Amazon Prime I watch on Nvidia Shield or other devices. That's a just little strange so Android OS take so many data every month. Sometimes I just do update a few apps from Google Store or Aptoide.

Maybe that will be a problem.

https://drive.google.com/file/d/1HpROILqcqL0sdA5zw1zjFkY5geGtsEiO/view?usp=drivesdk

This app is not a kill by a freeze a stock app.

My projector only boots into stock recovery. I've extracted rainman to my USB (FAT32 formatted), enabled USB debugging, done the commands through ADB but it just always goes back to stock recovery. I'm using the MJJGTYDS02FM Youth edition if anyone can help!

[MENTION=1944452]spoky1[/MENTION]2 thank you for this app. Added some great features to international 1080p white version.

Heard somewhere wemax could manage also 50hz sources. Thank you

Hi all,

I have Xiaomi laser projecter since 2 days and want to root it but my version is MJJGTYDS03FM and can't see any reference on this post. It's the black laser 4k chinese version with android 6.

Any luck someone success to root it. I reboot on twrp and installed Magisk. But when I'm back on to projector os, it told me that ProjectTivy tools denied superuser rights... is it because it's new model ?

Thanks !!!

[Android Software Development] archangelz:
Bought the Xiaomi Mijia 4k UST projector about a month ago and just put up my fixed frame screen. Just wondering does the projector tool allow you to do an 8 point keystone adjust like the Wemax version? I have a weird issue with the image where the left of the screen half way to the left corner distorts too high and the top left corner is too low. I checked this against my wall and the distortion is still there.

It's not as exaggerated as my super quick paint diagram, but it's still noticeable when you have letter box content and menus across that area. Only the left side is like that. Thought it was my screen but I checked it against just a flat wall and it's still there. Sadly the Xiaomi version 4 point keystone adjust is horribly limited. I did a quick search and apparently there might be a separate APK that needs to be installed for that mentioned in a few posts but I couldn't find the link. Sorry if this is a super noob question.

Mi Tools on unrooted device

I know you wrote that rooting is save, I just don't feel to confident on a device this expensive for now:laugh: .So I got some questions with freezing on unrooted devices:

1) What do you mean by "not automatically"? Just that I will need to run the commands from my PC? Or would I need to freeze the apps on every start?

2) Will the 3rd Party launcher start up automatically without root?

3) Will I be able to get the "change source" overlay without root?

4) General question (with or without root): will the autostart HDMI 1 behavior and CEC remote (starting and controlling my FireTV Stick with Xiaomi remote) remain the same?

5) root question: If I need a warranty repair, will I be able to undo root and will they still notice I rooted it?

--> TL DR: I want to change the launcher and freeze all chinese apps without root (I don't need more features like reduce input lag for now). will everything work as expected?
[Android Software Development] oYx:
Anyone knows how to disable absolute volume for Wemax Pro? Some BT headphones are way too quiet when connected to the projector. I have tried going to developer options, but I do not see the option to disable absolute volume.

As I'm a new user here, I am unable to post a link to a discussion that talks about disabling absolute volume as the solution to the problem. Please google "android absolute volume" and the first Reddit link should explain the issue and the solution.

Screen Flicker on Fengmi 4k

Hi, I have a Fengmi 4k projector. I was able to root and install Mi Projectivity tools perfectly fine. Everything was great but recently my projector has been having screen flickering on all inputs, although not on the main projector screen. Has this happened to anyone else? I've tried switching HDMI cables, and I've tried different devices, from my Roku to my Shield to my PS3. Any help would be greatly appreciated.
[Android Software Development] disco74:
Have you enabled HDMI 2.0?
[Android Software Development] jeffreyhsi:
I feel like an idiot ... but I don't see that setting anywhere. I was assuming it was turned on since Disney+ was streaming in 4k.
[Android Software Development] disco74:
You may have already done it but here goes.

you need to be on an HDMI source I.e hdmi 1.

Short press the button on the remote that has 3 lines then move down to 'playback settings' and click it.

Now scroll down to 'HDMI 2.0' and click. Now click 'On'.
[Android Software Development] jeffreyhsi:
I appreciate the help. I found it and now have switched it over to HDMI 2.0. BUT ... It still flickers. Perhaps I may need to reinstall all software. :(

Hello and sorry for my English I use a translator. I want to buy the xiaomi mjjgtyds02fm projector but I saw that it had released a global version but much more expensive so can we take the global firmware to put it on the Chinese version? thank you so much.
[Android Software Development] Casey.Bryson@gmail.com:
I posted this on the AVS forums, but posting here as well:

"I get flickering every once in a while, but only when I force 4K via the Mi Projectivity tools . I've learned you can switch it back to 1080p and then back to 4K to fix it. I haven't seen this brought up on the XDA boards, but that's the fix. I use my Roku Ultra for my "Smart TV" needs so having the Android TV at 4K is of no use"

Zoom function

Hi all

Everything is working fine on me Mijia Youth, but is there away to allow a larger zoom decrease (I think it goes down to 80%) ? My projector is mounted on the ceiling and I'd like to use the software zoom as I used my old projector's hardware zoom function. Thanks !
[Android Software Development] staru22:
Ok, so rooted my mijia 4k projector and now when it start I can see the screen with "innovation for everyone" and then it goes to a black screen.

The only thing I can do now is to press the Home button for a few seconds and it shows some recents apps, but can't open them, not even settings, it goes back to black screen.

Don't know what to do now..Followed all the steps corectly and installed ATV launcher and google apps and freezed the stock apps and launcher, that's all I did.

Any help?

Thank you

EDIT: Ok, I can't do anything, i get a black screen and the only think that I can do is to press the Home button for a few seconds and it shows the Settings Icon, but when I try to acces it it goes black again...also, when I hold the button with the 3 lines on the remote to acces settings it appears for a seconds and then dissapears.

[MENTION=848496]spocky12[/MENTION] trying to root international 8.1 version using rayman twrp but when adb rebooting I go on stock recovery and no twrp is starting. Tried to create a dummy signed update.zip but still verification error. It could be also because I put files on usb stick via macOS Catalina that has trouble in this cases. Tomorrow I will try to put files on usb stick via pc.

This afternoon I played with commands and via ADB shell i was able to force 4k resolution and it is ok also on international version. Was able also to dumpys.

Trying to investigate to toggle 50p and 24p but without root it is impossible. On AU flashed a300 Wemax that Gregory from PHC French site tested a couple of months ago, there is a resolution selection screen that could toggle also those resolutions. In your opinion dumping that firmware could be possible to add it to other projectors? For PAL users could be crucial...
[Android Software Development] oYx:
That happened with my Wemax Pro One too. That’s because your projector has no launcher selected or installed. I had to install ATV Launcher using a thumb drive, because the one from “install third party” option did nothing when I selected it.

---------- Post added at 01:36 AM ---------- Previous post was at 01:16 AM ----------

Make sure your thumb drive is formatted to FAT32.
[Android Software Development] ZX_DIO:
No way, tried with 2 usb sticks with fat32 but international version doesn't boot in twrp...I think the only way could be the old method but I don't have the cable.

When I try to get in TWRP and get stock recovery instead, it says:

Supported API:3

E:[libfs_mgr]Warning: unknown flag defaults

[MENTION=848496]spocky12[/MENTION] can I make something to help you trying to root the international version?

EDIT: i am afraid that international version is very similar to mi tv box s, so same recovery, locked bootloader and root only via test rom we have not
[Android Software Development] spocky12:
Hi,

Happy new year to all of you !

I've updated the "install 3rd party apps" apps list : updated a few apps, added Kodi 18.5 special build, added a compatible Amazon Prime Video app (as with Netflix, it's not an Android Tv app, but an older one, the last build that works on our devices)

Sorry can't give any OTA yet. I took a break during the holidays. There's still work to do before the next release, so the waiting is not over but hopefully it'll be worth it :)

Anyway, with the current version, the only issues you should encounter is :

- inability to install leanback keyboard from "install 3rd party apps" (it shouldn't matter to most people as it's already included in the Google App/Services package.

- lack of long press back button to improve input lag (but as long as you're not using monitor mode, you can still double clic the menu button to launch the tools and change the option there)

The issue with ATV has been remotely fixed with no need to update the tools.

I've already thrown a look at it and I can't understand the issue : in the stock keystone app, I can't see any code that hides the 4 points / 8 points toggle button for the mijia device. So I don't know why this device doesn't have the same behavior as the wemax/fengmi. I'll try to dig a bit further when I get time.

If you can boot twrp, it means that your device is supported. Try with another magisk version (19.x or 20.x) and when android is booted, make sure in magisk manager that MiProjectivy Tools have superuser rights.

1- You can run these commands from an adb shell on a computer. Then no root is required. You won't have to do it on every start.

2- It's supposed to work without root

3- It's supposed to work without root

4- CEC is not modified in any way. Stock Autostart HDMI will only work with stock launcher. If you change launcher, the Tools add their own autostart HDMI that will behave the same (except that you have to configure it in the Mi Projectivy tools app).

5- If you flash stock rom, root will disappear and they probably won't detect it's been rooted.

--> TL DR: yep

It might work, but for that, we first need somebody to find a full stock international firmware, and somebody else to try to install it.

Thanks for the tip !

If your device is rooted, with the last Mi ProjecTivy Tools, you can change the video zoom factor. It won't zoom the android UI, but depending on your usage, it might be enough for your needs.

Try another fat32 formatted usb device. Some don't work well on our device.

Can't say better than what oYx wrote : seems that you froze the stock launcher without installing another one and probably with an old version (2.x) of Mi Projectivy Tools (v3 acts as a launcher) to prevent this kind of issue.

I'll think about it and get back to you if I have an idea.
[Android Software Development] staru22:
Hmmm...maybe you are right.

I also couldn't install the ATV Launcher from your app, so I just installed it from Aptoide, maybe that was the mistake. Thank you

Btw. You are amazing spocky ?

EDIT: Tried to root it again but now I can't connect through ADB, it says:

"An attempt was made to access a socket in a way forbidden by its access permissions. (10013)"

I've tried to kill and start adb again, closed antivirus and firewall, nothing happened.

[MENTION=848496]spocky12[/MENTION] thanks for the awesome work. I just order a 02 version.

I was reading this thread from the start and a bit confused about the international 02 version.

So a few questions?

1. Is no progress on that front due to the fact you don't have a backup of the ROM from the device?

2. Or do you need an image from the Xiaomi OTA URLs to explore further the differences?

3. Any idea if the international version has the hardware required to show 3d (if software allows?)?

[MENTION=848496]spocky12[/MENTION] [MENTION=5214088]servo386[/MENTION]

I am at this stage.

Once in TWRP a mouse will be required. Make backups if you wish (at least "boot" partition that you'll need to restore before applying any OTA update), and then mount SYSTEM, and install magisk in order to root the device (it will be in "/udisk" and will be called Magisk-......zip)

1. I need to unplug usb drive and install usb mouse instead right ?

2. After I finished with back up and mount , I need to install Magisk in usb drive.

My question , there is already usb mouse in usb projector port. So how can I find another usb projector port?

conan - need firmware v. 1.3.123

Hi, I just bought Xiaomi mijia DLP projector YOUTH (MJJGTYDS02FM) and I kind of bricked it. I was trying to replace firmware in unit of my friend, but I sadly make a mistake and flash firmware v. 1.3.97 to my projector, which was build in firmware version 1.3.123 from factory. Now I have no light from LED lamp, but other works fine, I suppose. Projector can boot recovery and flash firmware from USB without working lamp, but I can´t find version 1.3.123 anywhere. After flashing v. 1.3.97 power button just four- or threetimes blinks and after that is OFF. When I press power button projector starts and after few seconds or minite projector reacting to remote controller and I can shut it down by remote controller.

So I need version 1.3.123 I think, but don´t know where to download as full firmware rom.

In case of succesful repair I am going to do another tests with other firmware for example with firmware from Global version (SJL4014GL), if i find it.

Pls help.

thx.

P.S.: Sorry for my bad english - not my native language.
[Android Software Development] matanmi12:
Try going into the device's original recovery and then pick the third or fourth option: "restore system".

The projector only have one USB port, so you have to plug a usb hub then plug usb drive and usb mouse to it in order to navigate on the TWRP and to flash Magisk.

I have another general question to everyone owning a Xiaomi 4k projector: I've got some black borders around the image. It's barely noticeable but its still there. Feels like the picture is not fully "zoomed" to fit the screen. There a narrow border around all edges with a wider one at the bottom.

Hope you can see what I mean in this pictures:

Is this normal? Does everyone have this? Can I change this somewhere?
