[Android Software Development] Bigboyhugetits:
I use 7.1 sound system with an amplifier worth more Than a Car and it doesnt fkin work
[Android Software Development] ZX_DIO:
Xiaomi laser support dolby, maybe virtual, but the issue is that for many of us pj is now useless. So we have to find a solution or xiaomi has to solve this issue.

Please send a mail to your local xiaomi service and a message to xiaomi global messenger account so they will hurry up to solve this bug!
[Android Software Development] Andrenauta76:
Tried that (dolby off in hdmi setup and in pj settimgs) but nothing changes.

I’ve sent a mail to the italian xiaomi support friday evening explainimg the issue, they replied saturday morning: problem has been reported to the main support center etc... hoping it’s a software issue.

Hey guys.

I got the international (Sweden ) version and got the update 2 days ago.

Model:

MiProjA1

Version:

9

Android Security patch level:

Augusti 5, 2019

Kernel version:

4.9.113

Build:

PQ3b.190705.003.1738

After the update i had to correct the keystone settings.

But after watching netflix, Plex and Youtube i notice that the picture are switching between dark and light.

Some scenes are getting lighter when its a dark scene, and getting dark at light scenes.

Its changing back and forwards sometimes every second or so.

Its like someone is cranking up the brightness levels depending on the level of brightness and compensating it. i Also had 3 random shutdowns.

Another strange thing is when I'm changing to HDMI port 1 it takes about 1 min for it to find my Nvidia Shield. Sometimes i need to switch back and forwards for it to find it.

Otherwise the menys are much faster. I have my connected to a Nvidia Shield and run everything from there and never run thing directly from the projector.

I'm gonna call the Swedish Xiaomi support center and report the issues.

Hi guys, I got the update 2 days ago as well. I have the international version here in germany. It works fine so far, luckly it seems that I got no issues. What I can say so far is, that it works much more usable in HDR and that the sound from built-in speakers are better adjustable.
[Android Software Development] ZX_DIO:
Will try to wait if picture and sound comes after a while. On mine no hdmi is working (immediately so far...)
[Android Software Development] Bigboyhugetits:
Really your using built in speakers.

IF YOU DONT USE AMPLIFIER U WILL NEVER NOTICE THE DOLBY DIGITAL PROBLEM WITH HDMI.

SURE NVIDIA SHIELD IS A GREAT THING, IT WORKS, SO YOUR PROJECROR ONLY NEED TO SHOW THE VIDEO. But it was over 1000$ So it would be better if it could do that.
[Android Software Development] Moselelvis:
Hi everyone,

I have the international version and since the update two days ago the resolution changed(no 4K support) and HDR is no longer available. Everything else seems to work fine

Walmart/US - MI 150 HDMI and Audio Issues

Just wanted to post that I also got the update about two days ago and have noticed very strange issues with HDMI source and audio recognition with my projector. I have had better luck booting up and going directly to a single source (I turned off HDMI-CEC, not sure if that helped) and can enjoy whatever I'm trying to view. But if I try to change source the picture will not always come up and/or the audio will never kick in. I am currently just rebooting each time this happens and pray that MI comes up with a software fix soon. Good luck everyone!!
[Android Software Development] ZX_DIO:
Turned off hdmi cec but still no picture and sound also using a single source and every single port...
[Android Software Development] werex:
I got in touch with the global xiaomi support, to tell them about this Hdmi and sound issue. The answer is really sad and no doesn't help at all.

Here's the answer from the global xiaomi support:

XXX,

Thank you for contacting Xiaomi Customer Support. I am Nandini and understand that you are facing an issue with your Xiaomi Laser Projector .

I regret to inform you that as of now we are not selling the Xiaomi products from our global website so I am unable to help you in this regard. Hence, would request you to coordinate with your point of purchase for better and quicker support.

For more information, you may refer to the Global Website: https://www.mi.com/global/service/warranty/ (If your region is Available) for updates regarding the warranty.

For any further queries, feel free to contact us.

I already tried everything. Turning dolby off, turning CEC off, using build in speaking instead of 5.1...

Nothing helped.

Right after the update I only had sound issues, which could be fixed with a reboot. So I tried to go with the factory reset which didn't fixed the sound issues but also added HDMI issues.

This is really bad...
[Android Software Development] ZX_DIO:
So we have a piece of junk on hands...great!! I will try to have support from bangood and then will buy something else. I understand low quality Chinese products but spreading an update that kills products I think it is abnormal
[Android Software Development] Graefe:
Facing the projector's previous faulty HDMI-CEC implementation I am very happy with the update, as power off by HDMI-CEC eventually works with Android 9.

However, auto-HDMI by CEC still does not work. For this I am thankful for Spooky's tool: Now I can power on and off with AppleTV remote and do not need the Xiaomi remote anymore. Great! :laugh:

The installation instructions were a bit confusing for me. Some clarifications for newbies like me:

1) Rooting is not necessary for the installation of the tools and to benefit from features like HDMI-in default.

2) For installation you should copy the apk file on an USB stick.

3) You need to install a file manager app in order install the apk file from USB stick.

4) Double clicking the apk file installs the Aptoid app first with which the tool app is installed second. The Aptoid app is difficult to use with the remote control.

It's a nightmare situation and one that Xiaomi need to get a handle on very quickly. To date I have emailed global support, local support here in Australia and got onto online chat support in the US. No response to my emails yet but the guy in the US admitted that they'd received a lot of support requests regarding the update and that these were being passed on to the developer.

For what it's worth here's the email I sent to Xiaomi's support teams:

I have the Xiaomi Laser Projector 150. Model number: MJJGYY02FM.

On Friday night (17th January) the projector automatically updated itself from Android TV version 8.1 to version 9.

Since the update to Android TV 9 I have been unable to connect the projector through HDMI to any of my devices - I have Yamaha A/V receiver, Fetch TV box and Xbox one s. See attached screenshots for detail of the projector software version and the message received when attempting to connect to a device through HDMI.

I can 100% confirm the issue is not caused by either the cable or the devices:

To ensue there is not a connection/cable issue I first connected the xbox one into HDMI port 1 of the projector and received the 'No Signal, 'The Video is unexpectedly unavailable' message. I then unplugged the xbox and using the same HDMI cable plugged it into an LG TV - everything worked fine!

In an attempt to fix the issue I did a full reset of the device using the Settings/Device/Preferences Reset function - unfortunately this did not resolve the issue and I am still unable to connect to external devices.

Please help, I bought this projector 8 months ago for my home theater, it was an expensive purchase for me and without HDMI connectivity it becomes of little use!

Note: I am highly computer literate and capable, with instruction from yourselves, of executing any patch or roll back of software operation you might suggest.
[Android Software Development] ZX_DIO:
Xiaomi italia answered via mail telling that is a known issue and they sent many feedbacks about it to xiaomi global and they are waiting for an answer and a solution. Hope they will move asap
[Android Software Development] idefix_sin:
Hi, wanted to post a quick update and question regarding my zodiac projector issues.

Wifi disconnect / unable to connect:

I narrowed it down to my Asus Mesh network. Out of whatever reason is the projector unable to connect. Initially a connection via wps was still possible (manual password entry always gave a wrong password notification) but since a few weeks now it will also not connect via wps anymore (says successfull but does not connect). Tried with a different AP and no issue. None of the other devices in my house (a lot) have issues with the asus mesh.

To solve this I'm now using a roku for all my streaming etc. This also solved the BT Audio no Youtube problem Xiaomi has.

Unfortunately 2 issues remain even with this:

1. The BT headset connected to the Xiaomi Zodiac has audio issues every 20 or so minutes. Basically as if the projector is unable to stream the audio for a few seconds (choppy audio). No issue if I use wireless headsets with their own usb dongle (logitech)

2. Audio video sync. There is a noticeable sync issue between the picture and the audio. Not sure if this is also BT releated.

Anyone has a tip regarding 1 or 2 above?

Thanks

Dear friend , please you kindly advise how to fix with google playstore and google voice. I have the same problem with your. google play store has been gone and google voice don't work.
[Android Software Development] a011528:
So i got the 4K device from gearbest (7 days from HKG) and returned non 4K version to the Mi Store - had to forefeet 10% reduction in refund price as i had used it!

My First impressions between the two - might be useful for those considering which one or maybe a swap.

The Noise level on the 4k version is at min 10 DB louder than the International (non 4K) version.

The interface on the 4k is worse vs the international version (mostly because the Chinese UI) (English translation aside) . So android 9 is way better.on the International Version.

Keystone correction (OMG) i thought it had 8 point on the 4K vs the International Version, but turns out its even worse, it doesn't have any real keystone correction, you can tilt up or down with some wired adjustment - which is totally terrible, the non 4K international version has 4 keystone corrections and is better.

3D plays - but for some reason i cant get my Acer 3D (E4W) DLP link glasses to work - i read some earlier posts about some Glasses not working - i'm still testing and dont know why some work and dont work - seems odd.

4k is obviously a plus but TBH i ran them side by side for an hr (before i had to take the other back to the store), and since most stuff is in 1080p i'm not sure if the move has been worth it from a $$ perspective, again i have a large 3D collection so getting that working is key for me, but having to fork more $ out on new glasses for this projector, also kinda defeats the object.

I have a Optima UST fixed screen and both projectors worked very well, if i play 4k content it does beat the non 4k version for sure.

hope this helps others.

Im interested in which 3D glasses anyone has got working on the 4k version

[Android Software Development] a011528:
Yes - ill be doing just that :)

do you or anyone know if it will be possible to add Keystone correction min 4 point ? or am i stuck with tilt (its a night mare to try and get it to fit mu fixed screen and i still have not achieved it
[Android Software Development] sodenn:
You go in setup menu then on display than on keystone correction and here on the left buton. You can choose 4 or 8 points.

Disable logging on console

---------- Post added at 10:29 PM ---------- Previous post was at 10:26 PM ----------

[/COLOR]

Hello,

Mine was flooding the console with :

[ 454.914174@2] BCM_BT: going OFF

[ 455.325000@2] BT_RADIO going: on

[ 455.325022@2] BCM_BT: going ON

[ 456.044147@2] BT_RADIO going: off

[ 456.044172@2] BCM_BT: going OFF

[ 456.455025@2] BT_RADIO going: on

[ 456.455047@2] BCM_BT: going ON

I guess because the bluetooth is on trying to connect to my speakers.

So I found how to stop flooding/logging in the console.

busybox dmesg -n 1

Maybe you could add it in the tutorial, and avoid some frustration or fear during the process ;)

Thanks again for the tutorial.

Cheers

Hello,

I've installed the latest version of your tool then I've rooted the projector,

I found the leanback launcher on aptoidtv (I didn't see it in your list of apps I could install from the tool)

I installed it and selected it in the settings under the home menu.

Then I froze the stock launcher, and couldn't go back to the home screen.

I figured It my need a reboot, I rebooted from the remote.

Now I just have a blackscreen.

Is there anything I could do from the terminal to reset it rather than reinstall the firmware ?

I'm not sure how to reinstall the firmware from the backup I took earlier.

Thanks

Jerome
[Android Software Development] spocky12:
Hi Jerome,

Yes, the leanback launcher is not included yet as it's part of the Google apps/services I'll add in a few days (I believe it requires the google services to work, so I don't think it'll work on a "stock" xiaomi firmware). In the first post, I mentionned that after installing a new launcher, you need to test it, to ensure it works before disabling the stock one ;). You now have a black screen because you don't have a launcher installed anymore.

Unfortunately you can't do anything from the booted projector (from your black screen) because ADB debugging needs to be activated on each boot, for you to execute ADB commands.

But I suppose you can do it from TWRP. Once TWRP has booted, make sure system is mounted, and then do as explained in the first post to manually unfreeze an app :

pm install -d -r --user 0 /system/vendor/app/TvHome/TvHome.apk

Hopefully, this will reactivate the stock launcher.

If it boots fine again, you can install ATV 0.11 (from my apps list), which will perfectly replace the stock launcher.

EDIT : I've updated the 1st post to give more details about launcher replacement :
[Android Software Development] rockpaperscissors:
I haven't had much luck with leanback launcher on my Wemax One. It doesn't work on my projector just like google apps don't. Did you test it to see if it worked before you froze the stock launcher? I think that it an important step. ATV launcher is what works for me.

I think a way out of your dilemma is if you have the Chinese Xiaomi projector or the Wemax One is to reload the Full rom 1.3.63 (6.0.1.935) found in the first post and then let it update normally OTA to the next FW after you reboot. I know It sucks to start over but i did it more then once messing around with stuff. If you download that file just extract it to the root of the usb (should be two files, a zip and another file) and start your projector into recovery mode and it will start the update. I'm not saying this is the only way, its just the way I've been doing it that works. Good luck.

EDIT: Or do the easier method described by spocky12 above. I didn't see this before I posted.
[Android Software Development] jhordies:
Hi, thanks a lot for the quick reply.

I tried to do it manually via twrp but I got a message like:

Null pointer exception Attempt to invoke interface method 'android.os.IBinder android.os.IServiceManager.getService(java.lang.String)' on a null object reference.

I was more thinking of a solution like launching your app via a command like;

am start -a android.intent.action.MAIN -n

com.abhi.ui/com.abhi.ui.LaunchIt (to replace with your app)
[Android Software Development] rockpaperscissors:
[MENTION=848496]spocky12[/MENTION] I hope you can explain what the "few modifications" are in the "OpenGapps TvStock 6.0 with a few modifications" It kinda driving me nuts that it don't work and id like to know why. I even extracted all the apk, permission, framework and config files from the tar files in the OpenGapps zip and installed then manually and the farthest i got was a frozen Google play login screen that i couldn't click the "yes" button on.
[Android Software Development] jhordies:
Thank you guys !

It took me some time to get there but I have the ATV launcher running with root access, cts on, stock apps frozen and even some menus in french thanks to more locale.

I had to reinstall the original firmware then let the update run from xiaomi.

Then stupid me rebooted in recovery to root the device and forgot that the rom was still in the root folder so it reinstalled the original firmware :(

I took a big risk cutting the power when the installer started, it didn't start afterwards but fortunately It was still able to reinstall the original firmware.

Then I updated ... again. Then rooted and except that I had to change the language back to English, I was amazed that all my apps were still there from before all this !

My i25 rii mini wireless keyboard /mouse/remote (xmass gift I got) works like a charm in azerty (thanks to https://play.google.com/store/apps/details?id=upsoft.keyboard )

The last part of the puzzle is having Gapps working, I currently have microG running with mitigated success.

I don't think we will ever get there but Netflix in HD would be very nice !

Thanks a lot [MENTION=848496]spocky12[/MENTION] for the amazing work !

Hi Jerome,

I'm not home for a few days, so I can't help much here...

What I can say is that I'm running my projector with CTS enabled and all apps disabled too and the settings are still available.

Did you try to reboot?

Could you get a logcat ?

Could it possibly be related to another thing you did (I still haven't used more locale doit exemple)? [MENTION=9544257]rockpaperscissors[/MENTION] can you access projector settings ?
[Android Software Development] rockpaperscissors:
No problems here. I can still access and adjust the projector setting.

I'm Running 6.0.1.1218 (1.3.97) with CTS enabled, all apps disabled and ATV launcher.

[MENTION=580686]jhordies[/MENTION] if your having issues I'd start over. I know it sucks but after you do it a few times you can be done in under an hr ;)

Also like you mentioned loading the full rom backup keeps some stuff like your apps and who knows what else, if you ever want to start totally from scratch and you can still access the recovery menu you can "restore system". After you do that it looks like when you first took it out the box. Good luck man.
[Android Software Development] jhordies:
Hello [MENTION=848496]spocky12[/MENTION], [MENTION=9544257]rockpaperscissors[/MENTION],

I have uninstalled many applications (including more locales 2, fake store, and "azerty") I still experience the same behavior.

If I click on the Projector settings (or the settings shortcut on the launcher), nothing happens, if I click a lot of times, sometime I can see the projector settings screen for less than a second and it disappear right away. Yesterday I click so many times and so fast that I even got to the wifi settings (which is the first item of the projector settings).

I tried to find a relevant trace with logcat the only one I see that could be relevant is something like "action canceled because of no focus on window".

Now I wonder if I have the latest version, I only re-installed the 935 then made the automatic update once. I see Build ID 8.5.4.1074.

So I tried to use the update rainman_OTA_6.0.1.1074-6.0.1.1218 .zip but It fails.

I guess, what I should do now is to reinstall from scratch with a restore system as [MENTION=9544257]rockpaperscissors[/MENTION] suggests. It's a pity because everything works as expected now just this screen that looses focus...

Cheers and thanks again for this amazing support, you should get paid by Xiaomi ;)
