No Root access on my Wemax A300

Hi there,

I am following every step to root my A300, but without any success. I have tried it with several USB devices and also with different versions of Magisk. There is no root access after reboot. Can you please help? Let me know if you need more details.

Thanks

Unfortunately it doesn't work.

Hey, I have Xiaomi Mijia 1S 4k (Chinese) / MiProjLas2 / model: MJJGTYDS04FM and connected to it a new Chromecast with google tv version and android 10. When I set on the projector support HDMI 2. 0 and set 4k60hz resolution on androidTV, after turning the projector off and on, the resolution returns to 1080. When I restart the Chromecast itself value remains unchanged - hence the conclusion that it is affected by the projector and HDMI settings. In the Chromecast itself, I can't turn off the automatic resolution adjustment as it was possible for mibox 1s. Does anyone have any idea how to solve this problem? [MENTION=848496]spocky12[/MENTION] have you met with such a problem? Do you have any idea have I can resolve this? adb shell wm size/density here are useless because youtube will still run in 1080 until I manually change to 4k.

Strange HDMI-CEC behaviour

Never had any problems with HDMI-CEC and my Anglee version projector. Suddenly HDMI-CEC with my sat receiver only works, if all other HDMI inputs of profector are empty. Even if there is only another single HDMI cable attached (without a device) HDMI stops working.

Did any other experienced such weird behaviour?
[Android Software Development] HeavyG001:
I noticed the same behaviour but I don't think it's a bug. To me this is more of a safety feature since there are a few resolution values there in the list that don't work properly. If the user presses buttons on the remote just too fast and one of the unsupported resolutions get selected/confirmed by an 'OK', nothing helps but a reboot.

So without this function (the projector resetting itself to the default 1080), I'd imagine it's only a full factory reset that could help getting the proper picture back again.
[Android Software Development] darkkatarsis:
You don't understand me, I can manually select any resolution on my Chromecast and the resolution is correctly switched on/confirmed. Everything works as it should - the video is displayed at 4k resolution. The problem is that when I reboot the projector, the settings from my Chromecast are set to the default 1080 and I have to re-set every time. I blamed it on the projector because when I reboot the Chromecast itself and leave the projector turned on, the settings do not reset.

Fengmi 4K L176FCN Bricked please Help

I followed the Steps in this Forum and when I '' adb reboot update'' everything was going fine and then the projector went off and would no longer do anything.

I have tried by going into Recovery mood by unplugging the projector and holding down the ok and back button, but nothing seems to be happening.

Please help me with this issue. is my projector Bricked ?

Hi

I have wemax a300 for a month now. Any suggestions how to get best image?

This is Chinese version

I use Nvidia shield tv so I didn't root the projector.

I want to know the best display setting calibration.

When I use Netflix with Nvidia shield, I can hear sometimes static noise . Not sure what is the issue.

Thanks
[Android Software Development] HeavyG001:
Still 99% sure it's caused by the projector. Just need to phrase it differently. As I explained in my previous reply it defaults back to 1080p@60Hz every single time you reboot it or switch it off and on. I reckon this setting gets synced to your Chromecast over HDMI during handshake. Try to disable HDMI-CEC, that might fix this.
[Android Software Development] darkkatarsis:
Ok now everything is clear!

That was the first thing I checked. Turning off HDMI-CEC does not help. I think I have already checked all the options, including the settings via adb shell... therefore I hope that spocky12, maybe has an idea.

Ps. I know that the projector itself does not allow you to change the resolution because the built-in drivers do not allow it, but I do not understand why it affects the connected device, which should normally support 4k (I mean new Chromecast - GoogleTV)

Hi [MENTION=848496]spocky12[/MENTION], I have a question, I have been using the mijia 4k projector for a year, everything is ok, maybe not quite because it started to run for a long time and the fans go harder, but that's not what I want to ask, this issue is almost solved with the help of Nikos with https://www.projectorjunkies.com/xiaomi-4k-laser-ust-projector-repair/.

My question is about ProjecTivy Tools, is it possible to rename HDMi connectors' abbreviations? So that instead of HDMI1, you could change, for example, to Decoder or HDMI2 on PS4 Pro? I will be grateful for your response.

Regards and I will be grateful for the answer.

Edit: [MENTION=848496]spocky12[/MENTION]

I have one more question about your tool.If the name cannot be changed, can the graphics responsible for each HDMI connector be changed? I have prepared such but I am asking you not to create problems.
[Android Software Development] Roystonkeith:
Hi, please I need your help i was in the middle of rooting my projector. When I connected the USB I ranf the ADB command and lunched reboot update. Projector turned off and on and had the little cartoon figure. Then the projector turned off and since then when I try turning on the projector the power light flashes about 5 times then turns off. I have tried booting into recovery mode by hold the ok button and back button at same time while pluging in the projector. But nothing shows up. The laser doesn't light up. However when I do try to go into recovery the power button light on the projector stays on and doesn't go off. Please help
[Android Software Development] Giulios86:
It sounds like you flashed a wrong firmware, since the cartoon figure shows up when you do a firmware flash.

Me and a growing family of users had this issue flashing the wrong firmware on the Fengmi 4K Cinema, however the firmware flash is not part of the procedure for rooting, you should have had only TWRP on your pendrive.

What files were in the USB?

What model is your projector?
[Android Software Development] jambanja:
I have the fengmi Cinema 4k PRO. When I boot into recovery i get the fengmi jerry page. I do a factory reset and then when I try to update the official Fengos update it fails at the last minute at the android robot page. How can I update my projector?
[Android Software Development] Roystonkeith:
I actually can't remember which files I had but I magisk v20.4 batman_twrp 3.2.2.0b and the platform tools. That was about it. Projector just turned off and then I tried going into recovery the laser doesn't turn on but the fan or coil can still be heard. If I don't press the ok and back button on the remote while it's turning on it simply blinks about 5 times and then turns off. Can this be fixed please need all the help I can get
[Android Software Development] dafunky:
Hello,

I currently have the Xiaomi 4K 1S rooted with batman_twrp 3.2.2.0b since day one.

I use it with a computer up to date (RTX 2080) at 4k resolution, under windows up to date.

- If I disable HDR in windows, the image is perfect black is black, white also, whatever I watch SDR or HDR content. Netflix shows the 4K label but not the HDR one ont its content.

- If I enable HDR in windows, the black gets grey and it's not ok. Netflix shows 4K + HDR labels ont its content. The color space is set on "extended" on both devices, the Xiaomi is set to "HDMI 2.0".

Any other feedback about Xiaomi 4K + Windows?
[Android Software Development] ABCD.:
Hi :)!

The app is awesome! Big thank you!

I've one question: If I set the beamer to start directly to HDMI input it will shutdown automatically after few minutes. I can prevent it, if I press any button on the remote control. I think that is not the intended use of this function? Maybe I have missed something to use it properly?

Is there any updates or a solution on how to have 4/8 point keystone on Xiaomi Mijia 4k? (Not Fengmi) :)
[Android Software Development] capstan12:
I got some smaller problems with my chinese Xiaomi 4k (first version) unrooted: I recently did a firmware update to 1.3.105. Since then I got 2 problems:

- a weird crackling/cracking sound which appears from time to time (independent from source). (The sound reminds me of the sound when connecting a 3,5mm audio jack to a speaker)

- a message appears once after around half an our after a rebbot saying "The system is running in". I guess what the message should be is "The system is running in low graphics mode" (as this is a error I found a lot for linux based systems)

Did anyone have issues related to this? Is there any solution?

Can I downgrade the firmware?
[Android Software Development] SyphonFi:
Is there a way to have both SPDIF and the main speaker working simultaneously? I would like to output stereo sound via SPDIF to Front Right & Left speakers, while having the projector's main speaker working as a center channel. Is there anyway to achieve this?

Backup for new Fengmi 4K Cinema (white)

Hello,

I've just get a backup file from /del/block of my Fengmi 4K Cinema (white version) I received a month ago.

I don't know if it match the hardware version you're looking for.

If you like I can share it to you, I know some users are waiting for.

I hope it help.

Best

Thierry.
[Android Software Development] Number__7:
Hi [MENTION=11256917]ABCD.[/MENTION] , the great [MENTION=848496]spocky12[/MENTION] is working on it ;). That is a behaviour by defect of the projector, so we need to avoid that automatical shutdown message, maybe triying a form to replicate that remote action by the app, I don´t know exactly.

Spocky is developing the solution and I will test it on my projector when he finishes, because he´s projector has a power button so hasn´t got that annoying function.
[Android Software Development] dducky:
Hey Thierry, yes please share a download link or send it to spocky12 so he can extract the firmware image. Thanks so much for your help!

Is there any way to disable HDR support "announcement" on projector side?

Background: in current Amazon FireTV settings you can set HDR to adaptive but it still detects HDR capability on 4k titles and within Netflix app

Opinions about 4k projectors HDR mode might be mixed but personally its way too dark for me :(

PS: Running an Wemax A300 aká Batman

I also have the same issue (on a different model though - Xiaomi Mi Youth CN mjjgtyds02fm), that seems happening only when reproducing from an external resource (Chromecast on HDMI) and disappears when Dolby is disactivated.

Problem in xiaomi mijia projector ( Property the 3D not working )

Hi guys

Problem in xiaomi mijia projector ( Property the 3D not working ) Chinese version Is this after the update or does it not work from the beginning, I don’t know because I bought it recently

Does this happen to anyone? Is there a solution to this problem please
[Android Software Development] speedngs:
I bought mijia compact projector global version a few days ago and i have this problem or question:

It happens to you that as soon as you turn it on it looks too bright? the background that is black for example from the home looks gray and after 1 or 2 minutes that brightness and gray disappears and it turns into black which is how it should be, you pass? Then the subject of focus, i calibrate the focus, I deactivate the automatic focus and when it starts (turn off and turn on the projector) looks out of focus (focus is gone), as it has not saved the focus

Can you really turn off HDR with this? (1st screenshot)

Yes. And you should set saturation to 100 to get good picture.

Hello@spocky12,

Bravo for this application and this crazy job I just wanted to buy the premium version, but I can not open google play, it starts and closes. You have to be in root mode to open it as if to have the premium version? Or maybe I made aimproper handling ? Because

I have a Xiaomi Mijia ALPD 3.0 which is rainman and not stable if I understood correctly.

Thanks for your help and well done for your work!

Hi @spocky12 ,

First, thanks a lot for your work!

(sorry for my English - I am French, like you, but I am trying to write this post in English in case someone else had the same issue).

My device is a Fengmi M055FCN and I have made a big mistake yesterday (forgot your recommendation) : In the menu "device resolution" I only switched the automatic change resolution to off.

And after that: absolutely nothing. I can see the checkerboard for one second and no more video. All I get is a black screen.

So I first try to reboot with only hold on the OK and Back buttons at the same time but nothing happens. Is there another manipulation to do this on my Fengmi model?? (because of the battery inside?)

Fortunately, when I've turned on with the USB thumb device inside with the Full rom files unzipped (2 times!! be careful , there is 2 zip files, you have to unzip the both (I don't see it the first time...) its works! !

But if you know another way to go to recovery mode with the remote on this model, it will be much appreciate.

I've another problem with the application MyCanal : the interface launches everything normally but when I play the video is freezed (I have only the sound) and it's like that 9 times on 10. This application is the reason why I wanted a android projector, did you have some solution please?

Thanks again for your tools !

Hi Spocky,

I would like to support your work because I use your application and root process for many months now.

I want also to buy the premium version but I can't as I can just input the password in Google Play but I can't apply it. There is no OK button to validate the purchase. Is it due to Goople Play Android TV or whatever ?

My projector : rooted Wemax A300

Hi @spocky12 !

Recently I've got a Xiaomi 1S 4K laser projector (MJJGTYDS04FM). Everything is great except the input lag:( Does your tool help exactly to my device with that?
[Android Software Development] skittletop:
I installed the projector tools on my VAVA, and with this, I managed to get Kodi running natively on the projector (although only at 1080p SDR)

I'm interested if there are other VAVA users in this thread, as I'd love to get more out of the projector tools. I know rooting is the way to unlock their full potential, although I'm a little hesitant to be the first to try that (if it's even possible)

With projector tools installed, I was unable to switch inputs on the main menu, I was able to enable developer options and get a few other specs on the projector etc.

With apps, as mentioned above I got Kodi working, Netflix worked for a bit then disconnected, Prime runs, but I guess I need GApps installed to get it to actually play anything. Plex refused to install.

I have an Nvidia shield for my streaming needs, so having these apps run natively is more of a bonus than a necessity.

The one big killer feature of the tools for me is the ability to lower the appalling lag, for playing some casual driving games. But I think the only way to do that is to root the projector, but I'd love to be proven wrong.

Anyway, top application, and thanks to all involved. I'll become a paid subscriber once I can figure out how to make the payment.

My Wemax Pro was working fine until yesterday. Till date I had only used my Amazon Firestick on it and everything was fine. I plugged in a USB drive yesterday and suddenly it went bad. Now every time I start it up it projects a black and white chessboard image for about 5 seconds and then turns off itself.

I dont know how to fix this. There isnt any repair centre here in India.

Please tell me there is a simple way to fix this.

Hello all,

I also got the XMJGTYDS01FM (Xiaomi 4K International/Global Version with Android 9) and any support added for this model to the amazing tool from Spocky would be really cool.

I also have a couple of other questions, maybe someone can help or at least point me into the right direction:

1) When connecting a Fire Stick 4k to the HDMI port and opening up the Netlflix or Youtube App I do not get 4k /UHD videos shown as an option. In Youtube the 4k videos play at Full HD, only. In Netflix I do not get the "UHD" option shown when selecting a video (I do have a premium account)

When using the internal Android Youtube app directly from the projector it shows 4k videos with no problem

2) On Amazon Prime (streaming from the Amazon Fire Stick) I do see "UHD" as an option, as soon as I start a UHD video from Prime, the projector switches to 4k resolution and 24hz. The video starts playing in UHD but the quality is pretty miserable. Lots of grain and worse picture than in FHD

Anyone with the international model able to give me some hints or has the same issues?

Thank you all for your help.

Regards from Austria,

Berni
[Android Software Development] friend76:
It looks like my issue in the earlier post comes more and more down to the fact that HDMI 2.0 is NOT enabled on my projector. I know that in the chinese Version one has to push the "3 line" menu button on the remote and there comes the option to switch HDMI 2.0 "ON".

Anyone an idea how to do this in the global version with Android 9? Thank your for your help...

Update! Found it! Need switch to the respective HDMI port (in my case where the Fire Stick is connected, to) and then do a long press on the middle "Enter" button of the remote ->> here comes the menu! :-)))
[Android Software Development] Jerome!:
Does somebody know of the Xiaomi Smart Compact projector (or its Chinese cousin) supports HDMI audio out? I know the projector has HDMI but does that function only as input as labeled? My idea was to play Spotify/Netflix on the device and output the audio to my receiver via HDMI, would that be possible? Or would an USB hub with HDMI port allow to work as an extra output? Or how are you organising the audio with a projector?
[Android Software Development] friend76:
The projectors 3rd HDMI port is a HDMI ARC port. So: that works.....

I have premiun in Xiaomi 1s chinese version

but was not able to give it superuser permission How do I enable it? The keyboard for google play store is all white with big characters one on top of each other. Is there a way to change that? Sometimes I cannot turn off the projector with the remote power button. Can you advise? Otherwise it is a pretty sleek software. Thanks for your great work.

It's because of 2k resolution option for the interface. You can simply back to 1080p to fix that behavior.

Hi,

As my previous post I said I use the VAVA projector but I returned it. I wasn't able to receive a sharp picture on my screen. Right now I am going with the Xiaomi Mijia 1s 4k projector, everything great!

I was able to root it, too, and paid for premium - thanks to the developer!

1st question: Does somebody have a full Rom of the device?

2nd question: how I can really see that my movie is played with hdr? Hdmi 2.0 Is enabled. With Amazon firetv stick 4k - at Vava the picture was much more vital. With xiaomi it looks like A grey "layer" is in front of the picture... Maybe I have to go through settings.

3rd: is it possible to play hdr 4k movies, when using kodi directly from the projector? Or it must be an hdmi gadget (firetv, Vero 4k,nvidia shield...) that sends the picture? Because directly from projector, I can choose only 1080p in video resolution, but via hdmi 2160p is possible.

4th: when I do display settings in the "standard original" options from the projector, does the other options I can do where the display profiles are, overwrite the settings I made before? Or do they interact with each other and it is best to put everything to "standard" in the original settings?

Lots of questions..

I've updated the firmware section wirth the latest OTA for rainman and the full firmware of jerry.

Hi,

1- You have it (should be a batman firmware, but not sure which version it is). Could you please share your /dev/block/backup file (copy it to an usb device using a root explorer app) ?

2- On mitv devices, usually, when HDR is enabled, the blue color in the menu changes.

3- UI is rendered as 1080p but on most apps, video is decoded in 4k. Not sure if kodi does the same

4- The "standard original" option doesn't have profile management at all. Hence anything changed by this app will override the current "user mode" settings.
