On another note: Does anyone know what google apps exist on default vanilla Android 9 projectors?

Google Play Store Android TV seems to be ok by manual install using https://www.apkmirror.com/apk/googl...20-xhdpi-8-pr-285862578-android-apk-download/ but the sign in button does not work.

The last Google Account Manager App v 7.1.2 does not seem to be compatible with Google Play Store Android tv. Maybe there is another apk is missing?

Hi Stefhong,

Did you manage to root the device again after getting a new replacement projector? I found on banggood that there's an international version of xiaomi fengmi vogue projector. which is similar to your projector

my fengmi vogue (goblin) is also running on mi tv MIUI 1.3.144 just like your projector

ROOTING: Is the Intelligent Projection System Recovery the TWRP?

Finally i could remotely trigger the adb Reboot and update on my Rainman projector (Wemax Pro 7000) via my Mac Computer.

The Reboot launches the Intelligent Projection System Recovery. Is this the right TWRP Software? They are limited options - WIPE CACHE, USER DATA, ALL DATA & RESTORE SYSTEM.

I guess this is not the right menu? Can you help me out?

Kind regards

OpaJoe

I see the same issue with my mijia projector since 2 days ago. has to go through the post on page 1 again.
[Android Software Development] evnow:
[MENTION=848496]spocky12[/MENTION] Thanks for the tool. Working well (no root, yet) with the newer Fengmi Cinema (not pro).

I noticed a missing step in how to uninstall packages without root :

Before the "pm uninstall ...", need a step to launch adb shell.

On the 2020 Fengmi - what is the status ? Did people who got their PJ bricked by flashing a (older?) firmware get the PJ working again ? I don't want to risk rooting if flashing a known working firmware is not possible yet.
[Android Software Development] spocky12:
I've had a look at it and found this message is indeed displayed when the projector doesn't detect any user activity for a while. This check is only done when the projector has cold booted, that's why it doesn't appear after a reboot. It's probably to prevent the projector from staying powered on all night long in case it automatically started : by CEC (although I almost never managed to get it working), or after a power outage (many models automatically power on when plugged in). As this issue seems recent, I suppose there might be a bug in their latest implementation. Could any of you send me the /system/app/projectormotor/projectormotor.apk ?

Changing the global zoom parameters requires root privileges, and is specific to each model. Don't think you'll find one on Google Play.

What's wrong it that you didn't fully read the tutorial in the 1st post ;)

When you say you don't have the button to reinstall gapps, you mean you don't have the "install 3rd party apps" button ?

Android audio chain isn't known for its efficiency. Progress have been made over the years, but remember we're talking about android 6.0 devices, some many optimizations available in recent smartphones are not available on our devices. If you add bluetooth drivers probably not up to date of optimized to the bone, you get this kind of problems. I don't know if this can be improved, if I find anything interesting, I'll let you know.

Also tried it on my cinema 4k pro when I got it, "adb reboot bootloader" doesn't reboot to the bootloader (fastboot) but to the recovery (you get the same result than running "adb reboot recovery"). "adb reboot update" still seems the way to go : it still reads twrp image on the usb drive, but refuses to boot it and in the end also starts the stock recovery. I still have to find why it doesn't accept twrp, I suppose it's related to the fact that recent recovery are encrypted somehow and our twrp doesn't pass the check.

It's not supported the its hardware (T962).

That's the stock recovery. Make sure your usb device is fat32 formatted and that the right files are present. If it still doesn't work, try another usb device, until you find one that works.

You're right, thanks !

Have a look at your hardware version l176_1 should be supported (we had an image from this device). If yours is different (fm_10), it's probably not safe to flash. Anyway, there's almost no risk in rooting this kind of device as the stock recovery can still flash the internal image when using the factory reset option in recovery. What is dangerous seems to be flashing a stock firmware from an unsupported hardware version (never caused any issue with devices other than fengmi cinema 4k, I suppose there are internal changes that require special drivers on some versions).

Wemax One Pro is not booting up

Hi!

I have a Wemax One pro (FMWS02C), sadly when I come to used it did not work.

The issue started after a lightning strike, the device was off, but connected to a Voltage regulator. Another device was connected to one of the HDMI inputs, and this devices was conected directly to the power.

Anyways, this is the issue:

When I just put the projector to the power it shows the logo of "wemax" in the screen, the led starts blinking, and thats it! Nothing else happens.

When I try to open the recovery mode, this is not oppening, I can only see the "wemax" logo screen. This time the led stops blinking, but still I cannot use the projector.

Can someone help me out?
[Android Software Development] ICOPETTI:
Thank you spooky!!

you guys think that if i buy the newest device from google store.google.com/product/chromecast_google_tv i will be able to fix my audio lag problem by pairing the soundbar with google tv instead of android? (if possibile because from firestick its not)
[Android Software Development] zeduck:
Exactly
[Android Software Development] blue_panther9_9:
Ok I will keep trying some other ways to find out this fastboot mode. I really want to get Google play store there with Open Gapps.

I also just noticed that developers options is now visible on my projector android settings. I couldn't find it last time, but I thought I wasn't looking properly. Sadly I didn't see unlock bootloader option there(OEM unlocking)

I'm going to change the USB option from charging to MTP, maybe if I connect projector directly via USB to my PC I can run adb fastboot from there.
[Android Software Development] blue_panther9_9:
That means your projector is going to be a dumb projector. Which defeats the purpose of having a smart projector?
[Android Software Development] ICOPETTI:
yes but no

At least for me "the purpose" is not to have a smart projector but to have:

a fornt soundbar, a projector and a remote to control all of them.

if i have to buy 70€ of something to make it work properly its not a problem.
[Android Software Development] blue_panther9_9:
hmm if you have a usb bluetooth dongle maybe you can also try that.

also check on other recommendation

https://www.youtube.com/watch?v=O5JUtqLiy1M

https://support.google.com/android/thread/12892715?hl=en

I wonder if your case is software or hardware issue.

Also can you try turning off your bluetooth remote while using your audio soundbar. just take off the remote battery.

maybe the issue is multi device connected to your bluetooth device?

Xiaomi Mi Laser UST Projector Tools Installation doesn't work

Hei [MENTION=544045]Spocky[/MENTION],

you were right. The USB Stick was not compatible with my WEMAX Projector. Now rooting is working out.

1. But i have issues installing your "App Xiaomi Mi Laser UST Projector Tools". It didn't install as APK File from the USB Stick (version 3). I can not find it in the Aptoid Store on the Projector to install directly from the web.

I tried it out with the older versions 2.17. Aptoide confirmed the installation. But it is not in the application folder. It doesn't open after installation either when i want to launch it directly after installation.

Update: already solved. Found your App here :good:

2. How can i activate the Web based Remote Control that you developed.

Update: already solved. Found it in your app :good:

Thank Your for your support and time!

Hi [MENTION=848496]spocky12[/MENTION] ,

This guy seems able to install gapps without recovery. https://xdaforums.com/android-tv/ph...w-install-sideload-gapps-google-play-t3431685

I'm trying to follow his script but stuck at adb remount. I was wondering have you seen this before? I could run adb root but not adb remount.

I found some recommendations to run disable-verity but I'm not sure what it is.

Would it be possible for you to check this tutorial for Android 9? Maybe it's doable without this bootloader.
[Android Software Development] evnow:
Thanks for the quick response.

Yes, my hardware version is l176_1 - I'll readup on rooting again and attempt it over the weekend.

In other news - I used the tool as the launcher - and invariably it stops working (usually as soon as I select an input like HDMI1). So, I guess we should just use ATV Launcher for now ? Any other launchers you (or anyone else) can recommend ? I'm looking for source selection in the launch screen (which ATV doesn't have).

Wire is not a solution because its too far away (can't be with UST) or you don't want the wire to show ? BT is a poor audio medium - simple RCA connection / Optical cable or HDMI ARC are all better.

You should be able to buy a BT transmitter that plugs to the analog or optical out of the PJ. That may or may not solve the BT audio delay issue, though ...
[Android Software Development] stevepalmer1977:
This is truly excellent, thanks for the development.

I've rooted my Wemax and installed the respective tools. Most things work very well. I have a few questions:

1) My bluetooth controllers (Xbox) pair well. However, after restart, they don't autoconnect again and I need to repair them. Any idea how to fix this?

2) Any hope to have Android 8+ coming to the Chinese Wemax version? Or are we stuck with 6?

3) How to update the device to the latest tools? Can do somewhere in the menus or need to do via USB?

4) I have two settings. I guess one is from the device and the other from google. It doesn't matter that much, but annoys. Any chance to merge them or remove one of them?
[Android Software Development] Stefhong:
Hi Blue Panther, no i got my replacement in from Xiaomi but havent tried to root it again. Bit scared to screw it up again :)

Are you sure that fengmi vogue is similar to this model? I read on banggood it has an LED light source instead of Laser?

Should you have some success/clue's please let me know. I have 1 year warranty so I can still do another attempt :D

Video projector updating

Hi Guys,

First thanks for making all this possible.

I've followed all this processes and was happy with my video projector with google for the past 2 months.

But since yesterday, after few minutes of usage the video projector reboot and attempt to install an update.

Obviously this is an issue as I cannot use the video projector for more than few minutes.

I thought it might be due to smart update but it is disabled already I toggled it on and off again to make sure.

Any idea what I am missing ?

thanks,
[Android Software Development] opajoe:
Does the search bar and the microphone work also on the main screen?
[Android Software Development] spocky12:
Thanks !

This tutorial is really old and won't work on our device.

"adb remount" is used to make the system partition writable. This requires root privileges. So it won't be available until we manage to root android 8/9.

It's probably related to the fact that you don't have any display profile yet. Just to to the display profile manager and edit the default profile. This should fix your issue. That bug is fixed in the upcoming version.

1- probably a bug in the bluetooth stack. No idea on how to fix it yet.

2- We're probably stuck with 6 unless xiaomi updates it.

3- The app is available on google play and Aptoide. Both stores will be updated when the upcoming bugfix version will be released. I'm also thinking about a self update feature, but that will come later.

4- MiTv android 6 devices ship with classic settings ui (=smartphone). The Google services package adds the settings dedicated to Android Tv. I can't really remove the 1st one as it would impact system partition and prevent firmware updates from working.

When "intelligent update" is disabled, most firmware updates won't download/install. But xiaomi has a way to force firmware updates they consider major. It's the same on FengOs too. For now, I fixed it by disabling internet access in my router (I'm mostly using a Shield for the "smart" part). There might be better options (like disabling the update service), but I didn't have time to think of it.
[Android Software Development] blue_panther9_9:
I see :(

The CPU is similar T972, the only difference is the output being a laser vs LED. and vogue has 32GB of memory and 2GB of RAM. Even the device name is the same fengmiproja2.

I saw on banggood that they have international version of vogue. I was wondering if you have tried contacting the FENGMI support on JD or somewhere on how to install international version ROM or even install Google Play or how to use fastboot? Sadly their support is only on wechat and it's in chinese.

Hi, I have Mi Laser Projector 150 Model: MJJGYY02FM with firmware version PQ3B.190705.003.2287 and since update have problem with shut down. When I select shut down projector does not shut down but restart. I tried factory reset few times, flashing old firmware and than again after OTA update same problem. So in order to shut down projector I have to pull out power cord. Does anyone have same problem? or have anyone any idea how to solve it?

Thanks
[Android Software Development] Number__7:
Hi [MENTION=848496]spocky12[/MENTION] , big thanks for your investigation, very interesting your contribution. I have tried turning on with the remote control and effectively, there is no random shutdown. However if the projector is booted by a plug in, then the shutdown comes.

Where can I found that "/system/app/projectormotor/projectormotor.apk" folder? If you tell me I could try to help you with this.

Do you think that if I make a factory reset to get the previous version of the projector (before the Xiaomi Update), would work perfectly without shutdowns? My goal is to have the projector without shutdowns in both modes, turning it on by the remote control or doing it through the plug in. And of course working together with your app.

Thanks! :D

Nvidia Shield + Google Home user

Hey, I think I have a similar setup to yours:

batman4k -> Sony DN1080 EU version (hdmi1) -> Nvidia Shield (2019)

I was able to add 'SHIELD' as a device in my google home, and therefore turn on the shield using 'Turn on my TV\Shield' voice command.

It has CEC enabled so it's able to turn on the receiver, which in turn - turns on the projector.

I've had some issues with the startup not being so smooth (in terms of HDMI handshakes taking too long, making me select the HDMI input from the projector menu, and then select the source input on the receiver - not a great experience).

As one of the features of this app is auto-switching to HDMI input on startup, I thought I would at least be able to skip the projector input selection part.

So I've installed everything according to the guide (had error 127 which was due to incorrect mount of SYSTEM - but I've managed to get past that). I've tried going premium but there was an error - I'll revisit it soon.

Anyway - I think I managed to get the startup of the setup using voice activation to the best point it can be right now, as my DN1080 seems to be the trouble with the flaky HDMI handshake taking forever (Sony has a known issue plaguing many users of this receiver).

I can turn off the entire setup if I press the power button on the projector itself (the correct CEC chain occurs) - but there's no way to voice command it to do so.

I will not use a smart outlet as a solution as the shutdown procedure must be graceful for the longevity of the projector components.

Has anyone managed to get this machine working with voice?

[Android Software Development] izanaghi:
Hi Again,

In previous post I mentioned that despite the smart update disabled the video projector downloaded an update.

now, few second after boot up the video projector reboots and attempts to install the update.

what would be the best way to stop this process or to delete the update file ?

thanks,
[Android Software Development] spocky12:
Not sure about rainman/batman and in general MiTv devices, but on FengOs, the file is automatically deleted and redownloaded each time the projector boots. Preventing the projector to access internet totally fixes this issue for me.

If your device is rooted, you might try to freeze the package "com.xiaomi.mitv.upgrade" (using the "Freeze apps" button) (if not rooted, you can still do this from an ADB console). Theoretically, this should permanently disable the OTA upgrade manager.
[Android Software Development] izanaghi:
brilliant I'll try that thanks :)
[Android Software Development] izanaghi:
I've tried to freeze this package but it didn't work.

So I dumped the traffic from the video projector and redirected a bunch of DNS request to a random IP.

this includes :

*.hpplay.cn

*.xiaomi.com (this domain for many things but used for firmware checking)

*.alikunlun.com (this domain is used to download the Firmware)

*.mi.com

*.gitv.tv

*.xiaomi.net

Hope it helps other.

Hello,

If you have the latest version of Fengmi 4k Cinema - Batman, your firmware version should be FM10. If so, would you share your / dev / block / backup in the forum or with Spocky. There are a few dead devices here in the forum with this firmware.

Thanks!
[Android Software Development] Number__7:
I have done a factory reset my Xiaomi Mi Laser projector 150 (International version), trying to get the previous version to the latest update. My aim was to go back to the previous firmware version, to see if thus the Projector didn´t switch off randomly on his own when is turned on through the plug. My surprise is that, besides the firmware version is the same and I didn´t get to return to the previous version, now my HDMI ports aren´t displaying anything. They are recognized but there is no image.

I´m a bit desperate with this because the only thing that I want is to have a projector that don´t turns off, and now my projector turns off and I can´t see HDMI image through it...

I have seen something about the engineering menu, but I read that could not work in International versions, appears to me a question in chinese in that menu with 2 options to choose.

There is no possibility to go back to the previous firmware without rooting and things like that?

I need help... Thanks!!

URGENT HELP! rainman projector wont turn on and cannot boot to recovery

First things first

Thanks for the amazing guides. I have ve been using it since I bought my projector almost a year ago. and the remote code was really useful to for home automation with home assistant.

I did the latest update on my rainman projector a few days ago since Xiaomi's latest push was restarting my projector after 5 minutes. Before doing the update I made a backup and then I second backup with the lates update and the Chinese version.

once the update was done I figured I could go back to the old version so I ran the restore (it seemed like a good idea at the time)

once the restore was done I no longer have a working interface (Chinese or otherwise).

here's what I have tried so far, I'm really hoping I'm missing something stupid and will much appreciate any help:

* tried doing the restore of the full rom by copying it to the USB drive and realized that none of the buttons on the remote work. I can't turn it on, off, or boot into recovery.

adb

* tried rebooting it thru ADB but the projector is not showing on the network either so ADB times out.

* tried loading the rainman_twrp_3.2.2.0 2 into the USB drive and I get a checkered flag. (this leads me to believe the USB drive works and is not the issue.) The remote still doesn't work.

Im hoping someone points out something that im missing

Please help!!!

thanks in advance
