yea mate - obviously :)

yes I had the white dots - but that has all gone now, and it boots correctly.

maybe its an expansion issue with something possibly shorting somewhere on the PCB.

no normal time :)

I don't know if its actually the wifi antennae - I just mentioned it to confirm what side I pushed on.

for me, its basically perfect now.

I'm not sure what I can do to help others?

I whole projector is really well put together, but everything is tightly assembled.

I think (I hope for others) its just a short - perhaps the case is sooo tight as the ambient temperature heats up, its causing a short as things expand.

as noted, for me, its working great now, and I hope others can correct the issue just by opening the case.

let me know if I can do anything else to try and understand the issues.
[Android Software Development] Mega Maniac:
Do we not have a way yet of preventing the OTA update? I'm surprised there is no option to turn off OTA updates in the settings. At the moment every time I turn off the projector it tries to update, fails, boots again and I can then turn it off. It means I have to go through this 5min loop every time I want to shut it down.

Really annoying, from reading through the thread it appears I may be able to uninstall root and Magisk then update, then reroot and reinstall... but that is all a bit of a pain, and will I have to do this next time it want to update.... would be much easier to just be able to turn off OTA is possible?

If you have a device with HDMI CEC this should be able to turn on the PJ when it turns on. (I have a Wemax A300 and I use my Shield remote to turn on the Shield, which then boots the PJ)
[Android Software Development] bloo10:
Thank you

I have Denon receiver with HDMI CEC connect to the PJ but it does not turn the PJ from some reason.

what people suppose to do when they remote stop working or damaged ?
[Android Software Development] spocky12:
The version that you can install from my tools works without a mouse, unless you need to switch profile.

The option is available in the settings and is called "intelligent updates" if I remember well.
[Android Software Development] spocky12:
My shield doesn't turn it on either, even if plugged directly on the projector and the option is turned on... Sometimes, my Chromecast or my internet TV box manage to turn in on, but not always.

Fengmi and wemax 4k have a physical button. For other devices, you can always use a connected outlet, as unplugging/replugging it will power it on.

update, another person on avforums reported that just by opening the projector, his problems went away
[Android Software Development] Kaudii:
I have a question whether it has opened and closed the projector, whether it has opened and closed it, i.e. whether it has only put on the housing without twisting the device ?
[Android Software Development] dj666jp:
Solved now

Thank you so much tihsamikah, you pointed me to the right direction.

Check my video here : https://youtu.be/geVQZxHYTXM

The ribbon cable seems to be the source of our problem.

**edit: in fact, it's what you meant by 'pushing the DLP black cable in a bit further'**

As you told : The box is too tight when the projector is closed.

When the box is closed, the ribbon cable get compressed

The video I took is from a cold start (after not using it during 2 days).

Previously I had to wait at least 2 minutes before seeing any display.

Now, I have to find a way to avoid the case touching this cable.

As you told : keeping the case not fully closed should do the trick.

For those who need it, opening the case is identical than on the video posted by wire_less :

The differences are :

-There is no screw behing the sticker on the back (SKU sticker).

-There is no screw at the center of the card on the back (the card with the hdmi slots)

-There are yellow warranty stickers on the sides of the card with the hdmi slots, theses stickers are hiding screws.

Please note that the side of the case where the power cable go is difficult to open, use a credit card or a mediator to unclip all the small plastic hooks.

*EDIT: There are some grooves lines inside the top case cover,

theses lines was pressing on the ribbon cable and the metal plate (farraday cage on the top right).

On the 2 last photos, I can see the horizontal lines marks made from the upper case design compressing the metal cage and the dlp ribbon cable.

Using sand paper to remove those lines inside the plastic cover can maybe avoid the case compressing too much the hardware.*

*EDIT2: Did a cold boot without the metal plate while projector was closed: it's not solving the problem (long boot time).

Back part of the projector was loosened, but front part was fully closed. will try to loosen the front part too in some hours.*

**FINAL EDIT:

Now, it's fixed for me too. \O/

I removed the side of the rubber sticked on the top of the DLP (the part under the red square of my 1st pic).

Then, I sticked it back but less tighten (so the black ribbon cable is more free).

In order to be sure that the projector top case will not touch the ribbon cable when it's closed :

I sticked 2~3mm of 3M Coated Tissue Tape on the top of this rubber (still on the DLP side).

I closed the projector case (just clipsed, no screw), started the projector and got no problem (fast display on a cold boot).

The only screws I put back are the ones at the back side of the projector (to maintain the card with the hdmi ports).

So my problem was not only the cover touching the black DLP ribbon cable, but also the grey rubber tape tightening it too strongly.

And the front part can't be tightly closed or late display on a cold boot appears again.

Apologies, my next question does not really got anything to do with the project. I'm just curious if anyone here managed to get Amazon Prime Video running on the projector? It is probably not being supported by Amazon for all I know but still, wonders if anyone tries and successful. My experience, it loaded the Android TV version of the app just fine but shows "Something went wrong" message when trying to play anything.
[Android Software Development] spocky12:
Already answered here :)
[Android Software Development] nyunyu:
Aww man. :(

Wonders if something can be done to make prime sees the projector as something else than a projector.
[Android Software Development] westcoastgeek:
Wow this is really lame of Amazon. Geesh. Nothing stopping someone using an apple TV box for non personal use.

Hello everyone, i have a question. Maybe someone had to clean it. The problem is interesting, switching programs on the Canal + decoder the projector makes sounds when the program being switched on has a high volume. Unfortunately, I find neither the projector nor the decoder the option of setting a balanced volume for all programs. Anyone have an idea how to fix it?

[Android Software Development] tihsamikah:
Thats great work mate :)

I've just left my case unscrewed but "mostly" pressed together so it looks correct

obviously not the idea solution - but at least you got things working :)

Others in the forum with this issue - are you willing to try this as well to confirm if opening the case resolves your faults?

maybe we have stumbled on a solution to this problem of black display or white dots :)
[Android Software Development] nyunyu:
Unfortunately among the general steps:

Thanks for the suggestion though.
[Android Software Development] dj666jp:
Tried to tightly close (just) the front part, slow display time came back again.

For now I can say :

- Cover must not touch the black ribbon cable (red square on the pic)

- Rubber on the top of this black ribbon cable was too tight (on my device, maybe not for everyone)

- If front part of the case is fully closed the slow display time start again (4 yellow rounds on the pic are the screw positions)

- The 2 screws on the front sides are long enough to keep them half screwed.

Hey mate.

How is the Mijia youth projector working with this root? Can you run apps like Netflix and General Google apps?

Tempted to go through the process but was worried I'd f### it up. Can I ask if you simply followed the steps on the first page here?

Appreciate any help.

OTA update

Hi Spocky, first off all thank you for all the hard work this device is amazing thanks to you! :D

I have the Xiaomi Mijia Mi / ZMiProj / model: TYY01ZM / codename: zodiac

Can anyone tell me where the setting "intelligent updates" can be found?

In any of the following menu's?

Device settings : launches the projector/tv/box settings

Android settings : launches the Android stock settings

Engineering menu : launches the engineering menu

Perhaps someone can show it with a screenshot, because I can't find it and it drives me crazy it tries to update continuously.
[Android Software Development] nyunyu:
Should be in device setting (the mi setting) in one of the options.
[Android Software Development] Jusch1995:
Nice work

Nice work,

But what I don't understand is why the start up time is getting longer after time. Do you have an idea why this is the case? I would do the trick as well with my projector, but I'm a little scared to leave the projector open. How open is the projector? Is it just that the screws are half screwd or do you really have to leave it completely open in the back?

Thank you guys for your amazing help
[Android Software Development] IronMan1977777:
I can confirm that I have got same problem with my Xiaomi 4k UST. Got it in 07/2019. Since last week longer startup time. Probably I will try the "case open fix". Does this void my warranty?

[Android Software Development] dj666jp:
I used the informations that was already available here and on Youtube and by opening it by myself, I could reproduce what tihsamikah found.

When he opened it, he noticed that keeping the case open was solving his problem.

He also found that something is faulty in the front part of the device when the cover is tightly closed.

'Khobeb Muslim' put a video on Youtube about pressing the cover on the area where -I could notice later when opening- is on the top of this DLP black ribbon.

mmmalas and tihsamikah already gave some good suppositions about electronic problems (something seems to be grounded somewhere PCB? Cable?), but only when it's cold. (You should read the previous pages)

Check the video wire_less gave and the explanation in previous posts to help you opening the device.

It's not so hard, just be careful, I think all necessary informations have already been told here or on AVS forum.

Check this attachment pics and you will see, the cover isn't really opened now, it's not taking dust.

(in fact we can't really notice on the pics, but there is an inner border)

**edit: Check the solution used by TK1825 on avforum:

https://www.avforums.com/threads/xi...-review-now-with-videos.2231266/post-27475714

**

Yellow warranty stickers are on the 2 screws of the card with the hdmi ports.

If you need to open it fully, you will have to remove those stickers.

Try to unscrew only the 4 front screw at first and to slightly open the front part of the case with a mediator or a credit card,

there is a chance it will fix you problem,

because maybe not everyone have the DLP black ribbon cable problem.

As tihsamika, I could notice that the long startup time appears when the front of the top cover is tightly closed.

We still don't know if another thing can make it appear.

I also had video problems that was linked to the black ribbon cable, but maybe not the slow boot time.
[Android Software Development] zythoun:
Hello everyone. I have the same issue than everyone, slow boot and stuff. In order to fix this, did someone tried to replace the cable with another one ?
[Android Software Development] dj666jp:
Read the post above your question.

When the front side of the cover is closed, the long to display delay appears again.

I would not mess with this cable. The cable itself don't seems faulty, just poorly connected / designed.

I don't think we can find some spare parts.

@spocky12 Hi, can you add a total running time in your app?

It seems there is no way to do it, but with this solution you would be able to display a 'Current ROM total running time' :

Hey team,

I just got the latest version of this projector and I wanted to get your opinion if this works.

The version I got was: Xiaomi Ecosystem WEMAX L1668FCF.

This is the latest 4K variant as you can see here: banggood. com/Xiaomi-Ecosystem-WEMAX-L1668FCF-4K-ALPD-Ultra-Short-Throw-Laser-Projector-9000-ANSI-Lumens-250nit-40001-Contrast-Ratio-Support-HDR-Voice-Control-Cinema-Theater-Projector-p-1504048.html?channel=emarsys&utm_source=emarsys&utm_medium=shipoutinform190813&utm_campaign=trigger-emarsys_prdshare_copy&utm_content=gakki&utm_design=131&_branch_match_id=716039311873459909

Now my what I am looking to get out of this is the following:

1) I want the lowest possible response time for gaming. So is there a massive improvement?

2) Is there a visual improvement to the picture or would I lose picture quality.

- The main reason I use the projector is to play UHD Blu-ray movies and the second reason is play games on my ps4 pro, Xbox one X and Nintendo Switch. I occasionally connect my pc for gaming.

For streaming I use my Apple TV 4K as my daily driver and on average I use this projector a good 8 hours a day.

PS: if you need a firmware dump of my device I would be happy to help.
[Android Software Development] Homar80:
You can go in Mi ProjecTivy Tools to shortcuts after Device settings choose About and press and hold down button until you see Legal info. Between Device name and Legal info you should be get a Total usage time. But some times doesn't work for a first time then go back to Device settings and again go to About press and hold down and you should be see Total usage time of your device.

I opened my PJ on Wednesday. More or less same problems without case. Also whenever I touched the black ribbon cable, image suffered changes (white vertical lines appeared and dissapeared in one or both sides of the image, or everything went black, or whatever), mainly if I touched near its curved zone, when it becomes vertical and goes inside other elements. I took several photos and videos I will try to include later (linked). In my opinion my PJ's behaviour becomes better if the cable has even more preassure, so I putted a plastic piece over the black ribbon cable, and then I closed the PJ again. As you can imagine, it is difficut to make some conclusion because as the PJ goes heater, its behaviour goes better.

So in my case, I think avoiding preassure doesnt solve anything. I'm going to make some tests later, and also a cold start.

Androide System Stuck - no Reset possible?

I run into an big issue.

Start drive seems to be full and android is not finishing booting - Stucks with the animated logo for ever.

the only way to turn of the projector is by cutting the energy.

but then there is no way to reset the system by remote control ("Back + OK").

Is there a way to connect a USB-Keyboard or USB Stick to solve the Problem?

Anybody an idea - our family put pressure on me :D
[Android Software Development] chunboon:
Hi Chark, did you solve this?
[Android Software Development] idefix_sin:
Hi guys,

I started to run into strange issues with my projector (zodiac).

First of all updating apps via the appstore never really worked. It shows the apps and when I hit update it simply runs the update or shows it as pending and nothing happens.

Google fix is active (shown when I enter the play store). In addition the onscreen keyboard with the remote control doesn't do anything (keys are know pressed when I press the enter button on the remote).

The other issue which recently started is that the projector keeps on loosing wifi when I boot it up. I have to again use WPS to hook it up.

In addition, once in a while when I reboot the projector it shows an updating message, followed by a black screen with the word ERROR at the bottom.

Any help, suggestions to get this fixed (he still works, it is just annoying) would be appreciated. Thanks !
[Android Software Development] bleunetizen:
Truly amazing progress - I was away from the scene for quite some time and now I come to this! Thanks a lot spoky12 for your hard work.

All seems to be fine, able to download apps from Play store and etc. All working fine except the voice button on my remote does not seem to work properly, just wondering if anyone had similar issue or has a solution.

When I press the voice button on the remote, the projector loads something and circle spins around then disappears. Not sure if related or not, but in search boxes, using the microphone option does not seem to work.

The install guide suggests "execute System / Accessibility Service, enable the service in accessibility settings (to fix "Google Play" ability to install/update apps and to link the stock remote control "Voice recognition" button to Google Assistant as well as other features)" so I assume there is a way to get this to work?

Also, from the main screen the google assistant search box at the top does the same thing - when I press to search (I assume this was supposed to bring a search box and a keyboard), it circles for a few seconds then just goes back. I wonder if my google assistant app isn't working properly for some reason?

Searched the thread and found multiple posts suggesting to double click the mic button etc but it does not seem to work for me. Is there a way to re-install google assistant maybe?

Any tips please :)

Thanks
[Android Software Development] KR_83:
I have the same problem on my MiTV3S 55". Starting the play store, it says "Google Play fix enabled", however when I try to install or update any app, it always says "Install Pending" never finished, no error message.

I also noted I cannot login into the YouTube app. Meaning it works fine (I can search and watch videos), accept I cannot login into my account. I guess it uses PlayService as well?!

So I guess this is somehow the root cause of both problems.

Which app version are you using, I'm running the new v3.0
[Android Software Development] bleunetizen:
Did you enable the projector tool from accessibility menu? I think the install guide suggests that that is what it fixes. I am using v3 also, mine works all fine except the google assistant not working..
[Android Software Development] KR_83:
Yes, I did (please see picture).

I don't have the remote with microphone (I have IR version, not BT), so I cannot test the Google assistant feature.

What do you think, should I file a bug at the GitHub project?
[Android Software Development] bleunetizen:
In the hopes of fixing Google assistant/mic issue, I tried updating google play store and etc from Apitoide and now Google Play store is gone from the android tv menu.

When I manually run the Google Play Store from apps list using a launcher, it says it is not compatible with my android tv device and suggests me to uninstall the update from settings, but not really sure if this can be done.

Could someone please upload a working Play Store and Google Assistant APK please?

The services such as youtube, google play music, games etc are all working fine so the google service itself seems fine to me..

Thanks guys

Also fixed the microphone issue by uninstalling updates for Google app

My (snipped) log is available at https://pastebin.com/vbKKuh43

I tried to install the app SpiegelTV (air.tv.spiegel.sptv), as can be seen at 20:36:33

As before, it always said "Install Pending", so I canceled the installation after 10 seconds at 20:36:43

Another thing that I tried before:

I deleted cache and all app data from store and play service, removed the Play store and Google App, and installed it again using Mi ProjecTivy Tools v3.0

I had to do the Google account sign in again, then I started the Play Store. I was able to install 1 app without the "Install Pending" problem without any problems. However, there were updates available for all Google Apps, so I installed them (again without the problem). However, afterwards whenever I tried to install any app gain, I run into the "Install Pending" problem again.

Removing all the previous installed updates (via Play Store) didn't fix the issue.

My Play Store version now is 16.9.42-xhdpi [8] [PR] 273610987

[Android Software Development] Aresias:
Hello,

Please, can someone help me?

I bought an Appotronics A300 (Wemax A300) that was flashed before being shipped. (bought on nothingbutlabels.com).

I don't know what they have modified and wish version.

Apparently the measurements show that the flash made the projector worse: worse colours, less bright, worse contrast and input lag when compared directly to one with stock ROM.

Can you confirm that there is only one version so the hardware can't be different?

How can I restore the original Chinese / English ROM? is it possible ?

Also where can i get this ROM ?

I don't need to have the App store or anything else since it will always be connected directly to a PC.

Thanks for your help.

Regards

Edit: apparently i just have to do factory reset ?
[Android Software Development] KR_83:
After some research via google it seems to me that the play store is actually causing my problem. There are many other people with different devices (and stock firmware) with the same problem.

I guess the old play store version that is installed via Mi ProjecTivy Tools v3.0 works, but after starting the play store for the first time, it updates to a newer version (16.9.42-xhdpi [8] [PR] 273610987) that is causing the problem.

There are many ideas how to fix the issue (delete data and cache, restart play store etc) but none of these work for me. I guess I have to hope for an update from google to fix this :crying:
