I played around with my TV, made factory reset etc and can definitly say now that this is a Google Play Store issue!

I made a fresh install with Mi ProjcTivy Tools v3.0, Play store version was 16.9.45-xhdpi [8] [PR] 275270192 and I was unable to install any apps.

So I made another factory reset, and manually installed Play store as described here (use google translate if necessary): http://4pda.ru/forum/index.php?showtopic=810785&st=8360#entry83543243

This gave me PlayStore version 12.8.24-xhdpi [8] [PR] 224427986

I was able to use Play Store to install a lot of apps without problems, even updating google apps.

After some time, the Play Store updated itself to version 16.9.42-xhdpi [8] [PR] 273610987 and BANG - same old Install Pending problem again!

I downgraded the Play Store back to the 12.8.24 version using ES File Explorer and installing apps worked again! Until it auto-updated the store again ...

So I need to figure out a way how to prevent the Play Store from updating itself - any ideas anyone?

Hey Spocky12! Thanks for this amazing tool. Been a lifesaver!

I noticed a bug with Noise Reduction turning back on by itself. Steps to reproduce:

1. turn noise reduction off (from input lag settings in MiProjectivy app v3.0)

2. Go back and open hdmi 1 from input menu in MiProjectivy app

3. After hdmi input loads, Go back either with menu button double tap or through launcher and check input lag settings. Noise reduction is back on.

Additional notes:

- Deinterlacing option persists fine

- tested with hdmi 1 & 2, with macbook and nintendo switch as inputs. Same issue in each case.

- Device: rainman

Is it possible to get 5.1 output from either HDMI arc or optical spdif on a chinese 4k projector?

Edit

I've seemingly fixed this myself. After a Rom reinstall I now have the RAW audio option.

Yet to see though if it transmits the proper format.

Sadly enough I still only get it to transmit linear PCM even from confirmed multi channel sources

So I finally manage to get proper surround sound.. I just needed to use the right app. Now I'm using MxPlayer.

So to conclude my question. You can get surround sound from the Xiaomi Mijia 4k laser projector. So far DD and DTS

If you do not want to damage the stickers get some prying spudgers and a hair dryer or hot air gun and slowly heat the stickers and pull them off. This way they stay intact and you can reapply them later with some more heat and you can use a credit card to push them down flush against the surface of the pj.

A300 acting like it has a ghost in the machine!

Hello all,

A300 Owner here.

I followed all instructions from top of the post to a T and it worked! But... 75% of the time the menu is acting very erratic and some apps fail to launch. Many strange behaviors and phantom movements when navigating.. Like ghosts in the machine.

Any help getting these bumps ironed out would be very much appreciated.
[Android Software Development] spocky12:
Sorry it took me so much time to anwser.

I don't know how to fix your issue without a special cable, as described in the complex root tutorial. If you didn't manage to fix your issue yet, just follow this root tutorial and you should be able to access a twrp and reset your device (or use the twrp file manager to remove files).

I've never had the pending install or keyboard issues. Concerning the wifi, it might be related to the updating message : your device might try to install an update and fails due to the modified kernel (for rooting).

Either disable the "intelligent updates" in your device's settings to disable the updater, or restore your boot partition, install the update and reinstall twrp afterwards.

What was the source of your updates ? Google Play store or Aptoide ? I always update my apps in the Play store and never experienced any issue with up to date versions...

Ans of course, as I can't reproduce the issue, I don't know what could be causing it.

Well, that requires clarifications from my side. I'll do it in an incoming post so that it's not hidden among personal answers and most people can read it.

That's weird, the Play store installed in my apps seem to work fine for almost everyone... don't know why an earlier version would work better for you :confused:

Thanks for your feedback. This is not a bug, this behavior is even described in the text on the left of the "input lag" screen ;)

Let me explain : each time you switch from android UI to hdmi (or even android video player), display settings are applied by the system. Depending on the settings you're using, it might interfere with the ones you've just set. In your specific case, I suppose you' in "monitor mode", which is the only one I've detected as forcing this noise reduction.

I'll add back the "long press back" behaviour in the next release so that you can disable NR from within the hdmi screen. But unless you have a specific use case, I'd suggest switching to user mode, which, with both deinterlacing and NR off, will be at least as low as monitor or game modes.

Did you try resetting to stock firmware, let it install the 536 update and root again ? This should not happen, and I can't think of anything that could be causing this. Wrong bluetooth apparing, maybe ?

What are exacly this erratic menus (does it act like you pressed the button twice ?). And when you say some apps fail to launch, do you have an error message ?

Also, if you're using a software remote (either my web remote "MiReCo", or the Goolge Android Tv remote app), do you see the same issue ?
[Android Software Development] KR_83:
As I wrote: One time right after installing the Play store from your app, I was able to install an app, then Play store updated itself and I had the Install Pending problem. So the Play store version you provide works - the blame is on Google because their newer version (which is updated automatically) causes the problem.

Nevertheless, I'm okay with this right now. Whenever I want to install an app, I simple first uninstall all Play store updates, then install my app. As long as this is working, I'm fine, I don't mind the extra steps, since I seldom install any new apps.

And maybe I can figure out a way to freeze the Play store up in its current (working) version ...
[Android Software Development] totalprakash:
I was indeed using monitor mode. The "long press back" feature would be perfect! Will go with user mode until then!

Thank you again!

Anyone have Kodi running on Spocky's fix?

Anyone have Kodi running on Spocky's fix?

I just get booted back to the Android menu when I attempt to open Kodi (Latest stable version). It installed from the Play Store just fine and gets to the point where it is setting up for the first run configuration and then boots itself and thats it.

I would love to use it with my A300 if there is a trick to make it work..

Thanks in advance!!

Hi,

It's been discussed many times already.

Latest working version is more or less 17.6.

Recently got a fengmi 4k projector. Batman. I'm new to projectors, but not new to Android and rooting.

Anyways, thank you for this awesome tool. It's amazing.

I did manage to root the fengmi 4k, but I have a few questions.

Coming from stock 1.3.105 (494)

1) after rooting, I notice that "Mi" is there upon initial boot. It was never there before. Not only that, after the "Mi" logo, the screen flashes some weird pattern of light and goes to the Appotronics triangle logo. Is this normal? It was never there before. Is it safe for the laser?

2) on boot, i'm still greeted with the Chinese picture of a purple/blue sky with a walking stairs/path on the right. Is this remnants of the stock launcher? Because...

3) when I try to "freeze" the stock launcher, I get an error message. Even tho I have a launcher that looks like Android TV, when I try to freeze the stock Chinese launcher, I get an error message.

4) I keep getting a message once every hour that I have an new update. It has a cute picture of an animated cartoon character. I decline it every time, but it's annoying that it keeps popping up. In the original Chinese settings, I've already checked off disable updates. Any tips to remove this pop up?

5) should I update to the new OTA 569? Version. 1.3.???
[Android Software Development] idefix_sin:
I can confirm exactly the same behavior on my Zodiac.

To check and reproduce I:

downloaded the stock ROM from the first page

Flashed it on the projector

did the OTA update (to the same version according to the XI updater....)

Rooted the projector as described

installed Projector tools, apps and play store

Play store version after installation is 12.8.24

Installation of apps via playstore works perfectly fine

after a while playstore updates itself to version 16.xxx

App installation as well as updates stop -> indicated as either installation or update pending. Doesn't do anything beyond that point

Went into settings app -> uninstall updates for playstore. Went back to version 12.8.24

Installation of apps via playstore works perfectly fine

after a while playstore updates itself to version 17.xxx (yes higher version then before, no idea why)

App installation as well as updates stop -> indicated as either installation or update pending. Doesn't do anything beyond that point

Went into settings app -> uninstall updates for playstore. Went back to version 12.8.24

Installation of apps via playstore works perfectly fine

Possible to include a freeze playstore option in the tools to prevent it from updating? Save this here: https://www.youtube.com/watch?v=3JI6YNSpAz8. Maybe it could be integrated as option?

Thanks a million !!

As spocky12 stated, it's be discussed already. I even posted the debug logs to the Kodi support forum which resulted in no support.

It's down to the Amlogic drivers not being configured properly, and therefore not an problem of Kodi. (If my understanding is correct).

Input Lag for L1668FCF (A300) or L176FCN (Fengmi)

Hello, I'm currently having a Wemax One Pro and I am thinking of upgrading to a newer model. But there must be two advantages to really pay for a new device:

1. 4k resolution

2. much lower "playable" input lag

The quoted paragraph is from the second post of our hero spocky12. Reading this, I would expect that the input lag is in a similar range as the 1080p models (as my Wemax One Pro). So somwhere over 75ms, even in Game or Monitor mode.

Now I found the following site:

https://www.passionhomecinema.fr/bl...00-l1688fcf-4k-second-round-lavis-de-gregory/

and

https://www.passionhomecinema.fr/blog/index.php/24/09/2019/test-fengmi-4k-lavis-de-gregory/

Scroll down, there is also an english translation lower at the referenced site.

For the A300 there are some sections like:

And even for the Fengmi it sais:

Now I am confused. below 35ms would be way better than the Wemax One Pro. It's still not perfect but it would be acceptable and a huge upgrade for gamers. But I'm not sure, it seems to be too good to be true.

Can somebody confirm that Monitor and Gaming mode have <35ms input lag for these devices?

Thank you.
[Android Software Development] spocky12:
1- I've noticed the "weird pattern of light" as well, but honestly, as my device is rooted from day 1, I thought it was there on stock version as well (it happens during the bootloader phase, so before android loading and so before any modification is even loaded)

2- Nothing to do with the launcher. It's the android loading screen (/animation). On the 1080p version I replaced it with the stock nexus animation (using a magisk module). Didn't try to install it on my 4k model.

3- What's your error message ?

4- In the projector settings, "about" section, disable the "intelligent update". Or : revert to stock (or restore your "boot" partition), apply the update, and reroot afterwards.

5- Nope, I've just tried, it seems it doesn't play well with fengmi/wemax, and only applies to mijia. I'll edit the 2nd post to mention it.

Thanks for your feedback.

In the projector settings, "about" section, disable the "intelligent update". Or : revert to stock (or restore your "boot" partition), apply the update, and reroot afterwards.

Concerning the Play Store, what's weird is that rainman/batman devices don't get any play store update. That's why I've never seem this issue. I'll try to find the update and install it manually.

Unfortunately I can't confirm anything. Gregory mentioned this low input lag in 2 tests : the modded Fengmi and the stock Wemax. He said the modded Wemax has a classic 100ms input lag. He even seems to think the differences he observed between both wemax is due to the rooted version (if it was the case, the modded fengmi would not have had 32ms as well)(and rooting don't touch the display drivers anyway).

What I can say is that when he first mentionned this low input lag, it was on the same device I owned and on which I never measured anything approaching. So I tested everything I could (stock 494, updated to 536, rooted or not, on user/game/monitor, with hdmi 2.0 enabled or not, different color range), I could never reproduce his measures, I have something around 100ms at best (monitor or user + my input lag improvements) and 150-170 at worst (user + dynamic contrast/color). I'm still trying to understand how that could be done.

Is anyone having issues with HDR on their projector? With the firestick 4K in HDMI #1, hdr content is wayyy too dark to the point that it is unusable even in pitch dark. I cannot seem to disable this in the firestick.

I'm not sure how to lessen the hdr effect because it's really strong. But I'd still like to have hdr, just not as intense!

When I plug the firestick 4K into HDMI #3 on the back of the projector, I believe hdr is no long supported and gets disabled entirely.

Anyone have a working solution to this?

Tldr: when hdr is activated, it becomes wayyyyy too intense and becomes unusable. It feels like the gamma is wayy to high, totally crushes the blacks entirely.

Focus drift issue on the Mijia Projector Youth edition

Hi everyone,

I bought a Mijia Projector Youth edition sometime back and I'm beginning to notice a focus drift issue that happens after about 20 to 30 mins of using the projector. The image starts to go out of focus and the focus has to be readjusted.

Since this only happens when you play something using the projector and not when on standby, I guess it is a heating issue.

Do you folks have any suggestions?

Thanks!

NEED CRITICAL HELP- I have absolutely no laser. No visuals. No boot logo, nothing. A laser that won't turn on (or dead?).

I have a fengmi 4K (comes stock with 494). I accidentially flashed the Full rom 1.3.97 (6.0.1.312) and now I have absolutely no visuals. The laser doesn't even come on. But the system does boot and into the OS. I know because I can iinteract and navigate around the UI and hear the button presses. And I can even shut down the OS by double pressing the power button on the remote.

However, I cannot go into the recovery by powering off the projector/holding "ok"+"back". At least the laser doesnt't even turn on for me to see if it does or not.

**Cant get into TWRP without adb which needs to be enabled via developertools.

I'm totally freaking out right now. The system is on, but there is no visual. What can I do?

Is there anyway to output the visuals to a TV or a monitor?

NOTES:

1) when I look down into the laser, there is a tiny white light that is illuminated but I 'm not sure if that's even the laser.

2) since I cannot see anything, I can still remember the power menu: Reboot - Power Off- Delay Power - Screen Off

*If I select screen off, the high pitch buzzing noise stop which indicates that the laser isn't dead, just not on?
[Android Software Development] spocky12:
Don't panic, it can be easily fixed (I know it because I had the exact same issue on my fengmi when I tested the latest update, which seems dedicated to mijia 4k [emoji16]). It's just that the low level drivers used to communicate with the wemax/fengmi laser are not present in 312 (or 569).

- Once fully booted to Android, power off your device with your remote control

- then follow the usual procedure to flash the full 494 firmware

- wait approximately 15 minutes to make sure flashing is over

- power cycle it

Nothing more is needed.

And to answer your previous question, to restore your boot partition, once in twrp, just flash the boot.img image from your previous backup, it will overwrite the current one. But I guess you don't need it now [emoji6]
[Android Software Development] lemonspeakers:
Thank you for your reply. But I am still confused on "the usual procedure"

How do I flash 494 if I can't see what's on my screen? I can't get into adb since my terminal says my projector is rejecting the approval (I guess USB debugging didn't stick?).

Hello,

I have the Wemax One projector. I have installed the custom firmware from this thread. I have a problem when I connect any PC to the projector. The colors look really washed out and the text is really fuzzy. I've tried updating GPU firmwares and Windows on both computers. I have HDMI 2.0 set to on and have tried many different resolutions and refresh rates and nothing helps. Before I installed the new firmware, I had tried using my old computer with the projector and don't remember it looking like this. Has anyone else had this issue?

Main PC specs:

R5 3600

GTX 1660 Super

16GB Ram

Windows 10 Pro

Edit: Just remembered this isn't custom firmware but a root solution and tool kit, so it probably has no effect on my problem.

A little more info: my Shield TV looks great on the projector with no fuzziness or blur.

Hi guys, any chances that Mijia Youth DLP projector gets update to Android 9.0 Pie? I don't like the 6.0 at all... Older Mi TVs got recently updates to Pie and even got Netflix certifications. I've bought it recently on 11.11 and love it, but the old Android is pretty drawback. Also is there a website with firmware updates just like MIUI phones have it? Thanks.

Hi spocky

Thanks for your work on rooting the xiaomi projectors.

I have successfully rooted my wemax a300 batman 4k

Suddenly I got a very bizarre keyboard like when using Netflix or any app with large letters overlapping each others , is that a known issue with the leanback keyboard ? Shall I reinstall the keyboard apk and di you have a link ?

Also for info I dont find the game and monitor mode in display parameters, not sure if it is because of the root operation + install of miprojectivy 3.0.0 + google apps etc as per your instructions, any idea ?

Thanks again !
[Android Software Development] spocky12:
No need to use adb. On the 2nd post, as per the "how to flash" section, you only need to extract the zip into a fa32 usb device, then shutdown your projector. Once done, just power it on with "ok" and "back" buttons pressed simultaneously. It should automatically boot to stock recovery, which will detect the update script and automatically install the full firmware. If you can use a usb device with an activity led, you shuold see it blink a few seconds at boot and then a minute or so while reading your firmware. Don't power switch just after the led stops blinking as the recovery still does some work after that. Wait for 10 to 15 minutes just to make sure there's no more activity going on.

Hi Regis,

The overlapping letters are probably due to ui being forced to 2160p (the leanback keyboard doesn't really supports this resolution). I'd suggest getting back to 1080p and rebooting your device.

Concerning the "game" and "monitor" display profiles, as Gregory told you, they are accessible on HDMI inputs, not on "local video". Just switch to an hdmi input, use the "menu" remote control button and go to "display" -> "picture profiles".
[Android Software Development] regis.larrode:
Thanks spocky will try that tonight !

>> I did a try and everything is ok , keyboard is back to normal, that was when I tried to force ui in 4k, you were right. Also I see the game and monitor mode, false alert .. Thank you !

Hi,

Can someone please confirm two things for me related to the Global Xiaomi 1080p version (model: MJJGYY02FM / codename: anglee)?

Hey Mickael! I Saw the dialogue between you and Gregory on PHC: Intriguing stuff! NOTE: I kept wondering if the differences between the two A300's could have been figured out in the Engineering Menu as it appears there are some hardware build date info there IIRC.

I tested the "Projector PQ calibration b494" and "Projector PQ calibration b536" builds extensively last night, but didn't see any difference--admittedly I though there was a huge difference but that was just my mind playing tricks on me once I A-B'ed it LOL. I didn't notice any version or build differences after installing the different files per your instructions and rebooting. How can I tell if I'm on the calibration file of 494 or 536? My current build is 536.

I also noticed that there appears to be no difference between Movie and Highlight picture modes??? What is going on there. The values between the two modes in the Engineering Menu are wildly different: 860 RGB , 255 Brightness for Highlight versus 700 RGB, 200 Brightness for Movie. I've adjusted the Movie down to as low as 150 RGB and 50 Brightness with no noticeable difference. I was hoping this was a way to adjust the Laser power and keep the projector cooler for a lower DB level of noise, but this is not the case. What do these RGB, Brightness, and XY values refer to? AND...do they work together somehow with the calibration files you mentioned?
