if you see that problem in the recovery screen, then it's unlikely its SW, and most definitely hardware.

next stage would had been if you were local, is to try to swap the logic (android board), if that fails then the other controller board.

to determine what is the faulty part.

if neither of those worked, then its the laser \ color wheel assembly, which as far as I know not serviceable.

I am going to investigate, color wheels \ DLP failure symptoms, and if ther is any remedy in general.

it could be DMD chip that is dying

here is how the 1080p version looks like, which most likely how the 4k will:

I had tried going into the main recovery screen and its the same issue. so it must be hardware

Hello all,

First, thank to the author for hard work.

Two questions:

- microphone doesn't work, I can activate voice récognition but it records nothing

- Cast feature is not working anymore, it was at beginning but it suddendly does not work

I have Batman version

Has someone same issues?

Thank you
[Android Software Development] AnantK123:
To activate microphone, you have to press and release the mic button. Then to actually get it to record, you have to hold down the mic button after the activation.

can you share other links where people having a problem with this projector, I also have batman (4k Chinese variant)
[Android Software Development] Homar80:
Me too can you check after how many hours you get a problem with yours batman projector.Chose more settings after about and under device name I have got "total usage time"Thanks.
[Android Software Development] mmmalas:
can you describe your issue,

is it taking long to boot,

because I am not seeing the other behavior that tihsamikah described
[Android Software Development] Homar80:
Hi I don't have any issues yet,but I want to know after how many hours Tihsamikah he get his problem. But maybe he have got a problem because he get overheating, he live in a warm country and a projector take it out warm air from inside.
[Android Software Development] mmmalas:
I live in the UK. It's not warm for sure.

As for overheating it wont be in startup.

There is a design issue with the projector, sooner or later, people will see this problem

What do you mean?.. I can't use the 3d feature with launchers other than the stock launcher?.. I bought an active shutter 3d glass and it didn't work.. I thought because it's not compatible with my youth edition projector but I never thought it is because of the launcher

[Android Software Development] mmmalas:
Gut feeling is that the soldier is drying up (because of regulation of not using lead in soldier)

This is the same issue that caused xbox ring of death. And pa3 deaths back in the day.

Looks like android board is intact. So I would say either DMD or controller feeding it is the issue.

Tearing down the projector is not that hard.

And with the right hands. It's not a hard job.

I will wait until mine get worse to operate on it. However if anyone want help to solve it right now then let me know, happy to provide steps.
[Android Software Development] spocky12:
1. Of course. As long as you don't freeze the stock launcher, it'll still be used.

2. The launcher is only this : a launcher. It doesn't affect features/drivers/settings... You can access the 3d menu by long pressing the "menu" button.

3. International models (only 1 for now, a 1080p called anglee) don't have 3d at all. The Googlified versions (with the tools here) handle 3d just like before googlification. There's no difference.

4. It's only to check if your device is rooted. But you can't root directly from android, you need magisk and twrp for this. I've renamed this option in the next release.

Nobody sent me one, so you'll have to be the first ;)

Once rooted, use a root explorer app and send me a copy of the /dev/block/backup file.

Sad to learn that some of you have a hardware display issue. And thanks for sharing your knowledge here ! Hopefully we'll be able to diagnose and fix it.

People experiencing this issue, please share your device model (xiaomi/fengmi/wemax) and if possible your production week (available in the engineering menu, 1st option, 3rd line)
[Android Software Development] vanzea:
Mmmm, my engineering menu is in Chinese, I have no way of knowing which is the temperature....

---------- Post added at 03:48 PM ---------- Previous post was at 03:21 PM ----------

I found it with help from Google Translate. 78 degrees, is that normal?
[Android Software Development] auldthief:
Thanks and sent you the link in pm! Please add it to OP for other users.

One more thing, the assistant doesn't accurately recognise my voice. This sometimes leads to hilarious results! If i tell it to turn on the lights, it will only hear "lights". It also misinterprets many words which is never the case with my phone, Google home and virtually all other of my android devices.

Also I need English-En for my Indian English accent. More locale doesnt have this option. Any pointers?

Any luck on automation? Still need badly to remotely turn on/wake this projector with google assistant. Can we do this through ifttt and mi home integration?
[Android Software Development] mmmalas:
70ies seems to be the normal range.

I think the issue occured, if temp is lower. The soldier joints are not fully expanded to fill the crack.

Next time you have this issue. Use kitchen plastic foil to block the intake and cloth on the other side to block the outake for 10-15 minutes.

Afterward reboot it should work. Please report back as I am building up information
[Android Software Development] dj666jp:
no logo on cold boot

Thank you for this great app and rooting tutorial.

I bought the Chinese 4k Batman version, and I think I will have the same issue described here and on the avs forum by 'D. Okamoto' and 'Raul Rico'.

Since some days, the 'Mi' logo and the blue boot image is not displayed during startup,

and the android launcher image appears only after ~10 seconds.

This problem append only on a cold boot, if I reboot the projector, the image is displaying normally.

I never had the white lines trouble (yet?!).

I received it only a month ago. As I bought it from China, it will maybe be difficult to send it back to repair.

As I didn't noticed the problem before, I didn't contacted the seller yet.
[Android Software Development] king-totti85:
I find android 6 is too buggy.. Any way to port android 7 to our devices?
[Android Software Development] mmmalas:
I feel for you man, I had weighted fixing it myself against sending it back. and I figured that fixing it is an easier route:

1- Xiaomi UK and global are washing their hands from it, Xiaomi china support does not speak a word of English.

2- there is no guarantee that seller can actually claim it under warranty, and if they did how long it would take espacilly that consumer laws are very different in there

3- if you send it back, then when it comes back to you, you will end up paying customs fees and VAT.

4- this is a big one, do you trust the seller not to take the projector, and you will not hear from them again, as there is no guarantee.

to fix this locally, you need to reflow the chip that is causing the issue, there was a youtube video (that I cannot find, I think it was taken down)

that video had dissembled the Mi 150 projector, and from memory, there is only one place where this can go wrong.

the main logic board where android lives, this is the main part that is different between Chinese and international models. however, this is fully working in this case because I am able to hear the projector menu navigating so this is not it.

there is a secondary board that looks like it processes the input signal (android or HDMI) I would put my money on this as the controller for the DMD chip is on this PCB. which is where the problem is.

you need to reflow it (ideally removing the chip, cleaning it, then reflowing the soldier) this is fairly easy task in the right hands.
[Android Software Development] Khobeb:
I have the same problem, no logo, flickers, goes dead with white light, not starting up for several minutes, getting worse day by day.
[Android Software Development] mmmalas:
if anyone is based in the UK, feel free to PM me your phone number and I will discuss the solution in detail with them.

I can also refer them to couple of local people that do reflow jobs. I think it would cost about £50-£100
[Android Software Development] Khobeb:
The problem is hardware surely

got the same problem, but i have realized that the problem is physical Hardware,

, have a look at my video (I can't post the link as am a new user) , once I press or touch the top of the projector, the problem (white pixels) starts appearing, and also vise versa, when the white pixels appear, when I touch it, it gets normal
[Android Software Development] mmmalas:
where are you based?

can you send me your youtube link via private message, I can publish it for you here
[Android Software Development] Kaudii:
Hello.

My projector is on its way to my place. Can you specify which model exactly is the problem?

Is it

4k Laser Projectors:

Xiaomi Mi Laser UST Projector 150" 4k (chinese) / MiProjLas2 / model: MJJGTYDS01FM

Wemax A300 / MiProjLas2 / model: L1668FCF

Fengmi 4K cinema laser / MiProjLas2 / model: L176FCN n

because it makes me afraid if my projector will be fully operational.

Same Problem

Hey,

My projector has the same problem. If I start it up no Logo, no picture, just a light with no image. After 3-5 minutes the picture appears. If I restart the projector everything is as it was in the beginning. Normal start up screen and picture. I don't have any problems with white lines or points (yet). If the picture is there it works completely normal.

Did someone found a solution for this problem?
[Android Software Development] mmmalas:
yes same projector in question, the problem might not be there right away. it will develop over time, from the looks of things start within months.

mine had been used since May 2019 so about 5-6 months in

I have an idea on how to fix it. but no one so far asked for my detailed walk through
[Android Software Development] dj666jp:
Mjjgtyds01f

Mine is MJJGTYDS01F, bought on gearbest on july 2019, received it on september.

After one month of casual use, problem started to appear (need 10/20 seconds to display image on a cold boot).

One week after, it's getting worse, bad colours and white dots during some minutes.

I saw your previous answer, I'm waiting for the gearbest answer, I'll PM you if their answer does not suit me.
[Android Software Development] Kaudii:
Thanks for the reply, this is not good news, but I will do nothing more, I will get a package tomorrow. it is a pity that previously there was no such information, I would pay extra and buy Fengmi or Wemax, since it does not appear on them. Thanks again

[Android Software Development] spocky12:
Hi everyone,

First post (and Aptoide) has been updated with the latest major version of my tools (3.00), sorry it took so long to release. Anyway, here it is :victory: !

Changelog :

- rebranded app to "Mi ProjecTivy Tools" because why not.

- stability : added a screen resolution check at boot. If a wrong resolution is set in the Android tv settings, the device won't be locked on the chessboard screen anymore, it will switch back to the default resolution (rainman and batman supported)

- stability : set this app as a Tv Launcher, so if all launchers are mistakenly disabled, the device will boot on it so that a launcher can be reinstalled

- UI : made menu buttons dynamic, so they won't show on your device if the feature is not supported

- UI : rewrote all submenu interface to use Android Tv UI. This vastly improved look and usability

- UI : changed menu icons

- UI : if accessibility service is running, the app can be opened by double pressing the "menu" button

- feature : added an option to change the zoom in/out factor for video display (external input and all media players)

- feature : added option to switch window manager to 4k (interface will likely not be totally fluid, though)

- feature : rewrote the option to decrease input lag so that you can disable "noise reduction" and "deinterlacing" individually

- feature : added a shortcut (qrcode) to MiReCo, the Web Remote Control

- feature : made the shortcuts section dynamic : it will now display all installed apps not natively compatible with Tv launchers (like the "Tv App Repo" app)

- feature : added "about this device" section that displays many details as well as the temperature sensors values

- improvement : made the hdmi input shortcuts compatible with international (android tv 8+) devices

- improvement : rewrote code to automatically start on a selected external input. This brings support for international models. IT WON'T USE the stock device settings anymore to select the input. Use the included parameter in "Input Settings"

- feature : added a shortcut to the stock "media explorer" directly in Tv launchers

- feature : added a warning if accessibility service is not enabled

- fix : fixed compatiblity with Netflix (not the Tv version, unfortunately, but the interface is totally usable). Due to missing DRM support, resolution is limited to SD. Users with a previous version of my Tools installed, please uninstall/reinstall the custom props overrides to apply the fix.

- internal : many fixes and improvements (and bugs ?)​

You can access the standard Android Settings from my Tools.

Hello, I have one more question if the Mijia 4k projector supports 4k 50 / 60Hz image. I have a digital decoder on the Canal + platform, unfortunately I can't set 4k image quality in it, only I can choose fhd. HDMI cable version 2.1, so it should work, unfortunately it is not, maybe you have some ideas what to do about it. Sorry for my English but I don't speak it every day, I use the translator.

internal board

great progress spocky, once your new tool is working ill get the new firmware and then try rerooting.

from watching one of the teardown videos the input bouard inside the projecter seems to be on an easily replaceable daughtercard

this card may include the android tv soc and os.

would like to know if the card in the v2 is the same, as if so there could be an easy upgrade to ATV if xiaomi or some alibaba sellers could get hold of or supply the daughter boars seperately
[Android Software Development] gregor1230:
Hi. I have some problems with upgrading firmware on chinees version of laser projector. Currently I have miui tv version 1.3.74 (stable) in about . So I am downloading OTA [user] from 6.0.1.1074 to 6.0.1.1218 (1.3.97) (NEW).

I have formated pendrive and after unzipping I am coppying 2 files: update-rainman.zip and xiaomi_update-rainman. Pluged in in usb port of Xiaomi laser projector. I am holding 2 bootons after power cabel plug in . And nothing automaticaly starts … Only recovery with few options like clear cache, factory reset and so on... Am I doing something wrong?
[Android Software Development] AnantK123:
I got this the first time I tried. I guess it is probably because the version on the projector was different than the version that the upgrade file was for. Going from a clean flash of the full rom and then following through to each upgrade rom worked for me.
[Android Software Development] gregor1230:
hehe so to much work for nothing . I will stay with current software and I will wait for OTA from china ...
[Android Software Development] rockpaperscissors:
What happened to me when I went out of FW order was it would start to load and then error out but I never had "nothing start" like you're explaining. Two issues I ran across since doing this stuff (rooting and loading fw) were usb drive issues. One was a defective drive which wouldn't show up while rooting and another was a 64gb usb drive that was formatted in exFAT instead of FAT32 which also wasn't recognized. Might not be either of these but its easy enough to check.
[Android Software Development] spocky12:
Yes, I'd say that is a problem of wrong partition format. Make sure if been formatted as FAT32.

Other update problems come in a second time, when it seems it has already started flashing the device, then it suddenly interrupts (fwiw, if somebody else has this issue, I suppose adding "--wipe-data" at the end of the text file should help).
[Android Software Development] gregor1230:
Hmm I have 64gb sandisk and ntfs format I will give a try to another usb stick with fat32. One more thing do I need to root my LP before OTA update ?
[Android Software Development] spocky12:
No, you don't need root to flash OTA. OTA will even disable root, so if you don't want to root twice, you'd better wait until it's fully updated.
[Android Software Development] AnantK123:
No root required for OTA.
[Android Software Development] rockpaperscissors:
Man! When are one of the international version projector people going to root so we can have a copy of their backup? I wonder what it will do if I install it on my Wemax? Spocky do you think it'll blow? :silly:

Is there a list of apks that can be sideloaded and work on this? I've tried chrome, amazon store and ugoos launcher none of which work

Hi, I just bought the Chinese wemax.

Got it into English, installed apps but Amazon prime video now working, is there an issue?

Is there any way to get rid of all this Chinese menus? For example with another launcher?

Maybe it s now easier to switch from Chinese to international firmware.? I m a bit scared of rooting processes on a such expensive device....

Thanks

Hi jordan69,

Please have a look at the second post of this thread where I compare international and Chinese models, and then list pros/cons of the Android 8.1 firmware used in the international model : 3d is not supported on this device (and the lack of communication from the Xiaomi developpers concerning this feature doesn't leave much hope for the future...)
[Android Software Development] Kaudii:
I was looking for this option, but I could not find it, the menu in MiuiTv is not very intuitive. You may be able to visualize it so that I can find it without any problems?

Edit:

problem solved i found. Thank you very much. I had this option disabled.
