Check the temperature sensors values (in my tools or in engineering menu), this might give us information about your issue.

Try flashing a full firmware too check whether it's software related or not.

Already explained in the FAQ. These projector miss the necessary drm, which can't be added.

Sounds like a software issue. Could you please try to flash the full firmware too check if it fixes the issue?

Unfortunately, the discussion stopped long ago. I can say with 99,99% confidence that rooting the device doesn't affect the display operations. If there were differences observed between fengmi rooted and not rooted, this has to do with either the firmware version or the build quality.

Someone on a French forum mentioned that he saw a real difference when flashing the PQ data from my tools, which would confirm it is just software.

As for the differences between fengmi and wemax, I can't pronounce myself.

Concerning the fengmi pro, I have one since 2 weeks. It's too early to make comparisons because I only make development on it (to adapt my tools). However I'll give a few details about it in an upcoming post.

Why do you prefer monitor mode upon user mode ?

Not sure I have a Franky firmware, so it's hard to say... Would you mind sending me /dev/block/backup if available, as well as /system and /boot ?

Definitely if we could get that, the image would be perfect.

Why do you prefer monitor mode upon user mode ?

I want to modify the sharpness control and set it to zero in monitor mode.

I have rotated to reduce noise reduction but it is not enough.

When I send 4k 60hz RGB Full 4: 4: 4 in 8 bit all the processing goes away and the image and motion are awesome.

Unfortunately the image shows interference when RGB is sent in 4K at 60hz. No one has succeeded.

Try sending 4K 60Hz RGB 4: 4: 4 8bit and you will realize what I am talking about.
[Android Software Development] Dogamondo:
Thanks Spocky, really looking forward to your upcoming post with your thoughts on the Fengmi Cinema Pro.

I am still undecided about whether to go with the A300 or the Fengmi.

Are you having any luck with rooting the Fengmi? Do you think it will ever get 3D?

Cheers!

Hello,

I have a Fengmi L176FCN and ended up with a dead unit after flashing the batman stock firmware from the first page of this thread.

It doesn't even switch on the laser beam.

Is there anything I could do to recover the original backup or we would need somebody with a functioning "unflashed" projector to recover it?

I contacted Banggood as another user with same issue and my only option would be to send it back to them with probably high costs involved, so any help would be very appreciated.

Thanks,

Giulio

Can't you load a Full rom of your model by usb as you have done with the update?
[Android Software Development] spocky12:
Not trying to root it right now, this will be the second step. I first need to add support in my tools (install 3rd party apps, freeze launcher, change input...).

Concerning 3D, I don't know the reason, but T962 (international models) didn't support 3D whereas T968 (chinese models), supported it. I haven't been able to find a details specs sheet of amlogic SOCs, but I suppose it's related to the embedded mali chip.

The new devices have the T972 soc, and none of them mention 3D support. This might be hardware related.

Sorry for this issue. I've added a warning ion the second post. Your device is probably more recent and relies on a kernel embedding newer display drivers. This will be fixed as soon as we have a stock firmware for these devices.

*** No it's becoming more urgent than before, seeing that a few people are stuck with this issue. Please, can any owner of a recent fengmi 4k cinema device (white one for exemple) copy the /dev/block/backup image to a usb device and share it with me ? ***
[Android Software Development] nathaimu:
I would love to.

How can I do that ?

(sorry not very familiar with android)

i'm on Androidtv 9, 2020 april 5, 4.9.113 (May 28) - Build : PQ3B.190705.003.2171 ( international version Mi Laser Projecteur 150 )

i got update androidtv error, when i got error screen, need to Wipe data/factory reset, the option try again don't work.

for example, i play youtube this afternoon, no update for the moment but i think this night, the update will come back.

anyone have the solution ? its possible to disable the update ?
[Android Software Development] Giulios86:
Thanks for the feedback Spocky.

I guess it's worth waiting for the ROM to try if it solves the problem before sending it back.

Since some people might stick to the original post, would it make sense asking for sharing the stock ROM of the newer FENGMI in there on top of the warning that you added?

Again thanks for helping!
[Android Software Development] spocky12:
System and kernel (aka boot) should be part of the backup you made from twrp.

As for backup, I can't garantee its present on your device, but it requires root, so for now you won't be able to do it.

Concerning magisk, error 127 is supposed to be related to sdcard/usb mount. Usually, if you boot the projector with the usb already inserted, it should directly be mounted. Perhaps it will work better in this case.
[Android Software Development] nathaimu:
OK so I have indeed a backup but :

- I had to store it on Internal Storage because my USB disk shows very low capacity when in Twrp (it is fine in windows, tried 3 differents drives, everytime the same thing)

- I then transferred it to my USB drive with a file explorer I was able to install.

I will share this with you no problem.

USB is connected when booting because I am launching twrp from it using terminal commands, as instructed at point 4 in this post >

https://xdaforums.com/showpost.php?p=77860186&postcount=9

I might try and copy magisk .zip file on the Internal Storage, boot to twrp (on USB) and find it in the install section.

>> if I find a way to Root, I will gladly share "Backup" with you.

edit : [MENTION=848496]spocky12[/MENTION], I sent you a PM with a link to download my backup files.

Hi to all,

I have an Xiaomi Laser Projector "L185JCN", may be able to root and install these tools?

Thankyou
[Android Software Development] Jah85:
its possible to know your androidtv version, date, build and international or other version ?

==> i'm on Androidtv 9, 2020 april 5, 4.9.113 (May 28) - Build : PQ3B.190705.003.2171 ( international version Mi Laser Projector 150 )

Because on the projector boot, its update checked, i need to unplug the rj45 to boot on androidtv without error.

Anyone have that ?
[Android Software Development] nathaimu:
So I tried to copy Magisk's zip file outside of my usb, but got the same error #127.

So I'm stuck, it seems this version of twrp has trouble with handling USB on my device. (mouse super glitchy, USB disk showing wrong space, error 127)

Maybe I can try a more recent version of twrp ? Any ideas ?

L185JCN

As mentioned before I have recently owned the L185JCN long throw projector, is there any news on how to root this device?

The seller made me find it already set in English and with some apps like the playstore and chrome installed but obviously not working!

Could there be some apk that I can install to make a system / firmware backup so I can be useful?

The file manager / installer (hidden link) appears only if I put a FAT32 key in the USB port. The player also supports NTFS...

I have installed "Aptoide" to start trying something.

If you need anything you tell me what to do and I'll try.

Hi guys,

I manage to buy the new Xiaomi Projector UST (Xiaomi Mijia 1S 4K codename : I can't find it ^^ ) and I wonder if the app can be compatible with the new model.

Hi

I have anglee model and tools 3.0 installed. I have noticed that voice search pop up unexpected. And I must push back button to cancel voice search. This happened after tools 3.0 has been installed. I only set up auto load input HDMI 1. No other setting changed. Can this fix it ?
[Android Software Development] munawarfairoozz007:
bro i also have anglee , mjjgyy02fm , do you successfully root it, also can you expalin how to setup auto load input to hdmi using the tool
[Android Software Development] uskov.artem:
No root at the moment for anglee model (

For the auto load is pretty simple:

- download apk to USB stick drive

- put USB stick drive into projector, explore to apk with any file manager and install it

- Open in projector setting - accessibility options and enable MiProjTool switch

- open application and select "input setting" and choose HDMI port that you want to auto load.
[Android Software Development] raspel:
I join the request for 3D button
[Android Software Development] McBanjo:
I’m also getting this quite often when using the remote. It’s very distracting. Any ideas? I suspect it has something to do with the accessibility service as it changes the voice search button on the remote to bind to google assistant. Using anglee model (international version).
[Android Software Development] westcoastgeek:
I had my projector disconnected from the network for a while and when i connected it, it auto updated to a firmware that seems to have made it almost impossible for my hdmi devices to connect. They used to work pretty good before now I am lucky if I ever get a connection. If I install this apk and set of tools will it overwrite the new firmware I loaded and replace it with something that is more stable? I have read there was a firmware that really messed up HDMI inputs on some units. maybe that's what happened to me. Is there a place to find the xiaomi old firmwares. something form last year to see if that helps, or will doing this mod overwrite the Xiaomi firmware?
[Android Software Development] dracsirk:
Yesterday received update. Apart from Netflix compatibility and bluetooth speaker mode( changes projector into speaker and allows to switch off screen) they changed movement detection screen. New picture with additional buttton which allows you to switch off movement detection sensors from this screen. Security patches from July. Nice update for me. Only issue remaining for me is that hbo does not work and shows error -5 at the start of playback.
[Android Software Development] spocky12:
If any owner of the international model did not update to the latest version yet, I'd be interested in getting a logcat which should contain the link to the update ota (or a direct link to download the ota if somebody have it).

This is related to the accessibility service. Next app release will take care of this.

What do you want it to do exactly? Can't you access it by long pressing the menu button ?

Note that I can't add 3d menu on international models because it's not present at all (and probably not supported by the t962 soc anyway)

2 full firmwares are available in the 2nd post of this thread. Using my app, you should be able to access engineering menu and probably reset hdcp keys.

Latest update of international version break the image. Colors are wrong, loosing focus after rebooting
[Android Software Development] dmitriylm:
I received the latest update on my international model (anglee) a few days ago and initially my hdmi inputs were fuzzy but after performing a factory reset they fail to work altogether (black screen or no input). Not happy about this. I tried to find the hdcp reset option via the MiProjecTivy v3.0 tool but it doesn't appear in my engineering menu.
[Android Software Development] NewStranger:
HDMI input downscaled after update

Same with my beamer (international version).

After installing the latest update 2 days ago, the hdmi input (1080p) is shown in a really poor quality.

It seems the picture is scaled down to standard definition and upscaled afterwards. Sharp lines become fuzzy.

Once I managed to 'repair' the picture by changing the 'image mode' (standard, user, ...).

But the next day it reappears and changing the 'image mode' does not helped.

I still have not reverted to factory reset, because I would loose my installed apps....

I would be thankfull for each hint to repair the beamer. Please.

(By the way: Each update on the international version made hdmi worse.

The initial fw worked fine with HDMI. After the next update I got each day problems on finding the hdmi signal. And the beamer started to reboot from time to time during hdmi playback. And now, after the actual fw update High definition is gone.)

Thanks for your helpful post. I have the same problem, but in the engineering menu, there is no «*HDCP key*» option.

Do you know, or anyone know why?

Many thanks for your help,
[Android Software Development] dmitriylm:
I'm assuming its not available on anglee models as the tool was designed for the China market projectors. So we are screwed as far as I can tell and I've spent a few days trying to get it working.
[Android Software Development] Dmo29:
As soon as I’m able to use apps, it’s not a big deal for me, except for:

Getting the sound trough the Devialet freebox player, far better than the integrated sound bar

Having my Apple TV in HDMI to be able to watch APPLE Tv+ / amazon prime and my iTunes movie (bought).

I assume I will have to wait for a new update, but with the apps «*Molotov*», «*canal play*», «*Netflix*», it is still quite an excellent product!

I tried to connect the freebox Devialet player via optical cable (SPDIF) or Bluetooth with no success... I spent 2 days looking at solutions... hoping there will be a quick upgrade of the software in the following days...

July 2020 update causing HDMI Video issues

Hi all,

I have a Xiaomi UST 150 Projector (Model MiProjA1). Well First of all I was unhappy with this purchase because the video quality was very bad in the default modes (movie etc) provided, so after a lot of calibration in the user mode, I got a decent picture. I could not return it because I had ordered from gearbest.com and they were no good in responding to me at all. Well, at least I used it as my Bedroom setting and was happy with that, and it's about an year now.

Come this week, I saw an update that included Netflix, etc, I Installed the Update without even thinking. Now while video from the default Android TV on the projector looks good, my connected HDMI Sources (Fire TV and HTPC) video looks like watercolors, no matter how much I have tried the settings it looks pathetic, I also tried the factory reset but unfortunately the base os has been updated to the latest so no use there.

I good to the boot menu, downloaded the older version but the recovery is failing with a message saying I cannot revert to an older version.

Anyone else seeing this issue? what is the best fix? how can I undo this update and go back to my older setting.

Really appreciate help from the experts here.
[Android Software Development] chinaskirules:
Same problem here with the anglee model and the latest update. I have written to service.us@xiaomi.com, at the moment they have not answered me.

How is it possible to throw the image wireless with a Windows 10 laptop?

It works with Android phone.

How can I fix that?
[Android Software Development] craj999:
I even tweeted to Xiaomi and shared with xiaomi US Support

I Tweeted and shared the info with the support team. Hope some officlal update comes out sooner.
[Android Software Development] micobaxda:
I can confirm, that the picture quality became worse after the update. BTW Netflix plays only HD content on my anglee device and not 4k content.
[Android Software Development] Dmo29:
I had an answer from the French support, that proposed to me to boot on the debug menu, and choose «*wipe data*», supposed to place the device in the factory state.

I’m not sure this will work, but I’ll try this evening and let you know... if someone has already tested it, let me know...

Edit: tried to apply the answer: no result, don’t loose your time this is useless...

Any chance for Xiaomi Mijia 1S 4K UST (MJJGTYDS04FM) to be added to supported devices?
[Android Software Development] craj999:
Same result - Support shared the same old steps.

I got the same response from Support, I shared my screenshots so waiting to see some update soon.

Good to know atleast they are responding.

Also, if it is worth it, the Movie mode for the HDMI sources looks decent with the default settings, I have the HDMI2.0 off on these sources. Yes but not too happy still.
[Android Software Development] chinaskirules:
Same here
[Android Software Development] NewStranger:
The poor hdmi picture appears, if the 'image mode' 'user mode' was selected before switching to the hdmi input. Other 'image mode' work fine.

And the 'user mode' iorks as well, if selected AFTER switching to the hdmi input.

So, Xiaomi screwed up the 'user mode' only and only if set as default.

Can anyone confirm my observations?
[Android Software Development] Dmo29:
Had the same answer today. I explained that this update was supposed to be done on revision 8 of Android and that it would be very nice to have the same procedure with updated files...

Hoping we’ll get to a solution soon!

Good news is they are quite responsive...
