Hi! I wanna ask if someone has installed viu app and it made other apps force close? what can we do? is it becasuse the firmware or hardware issues?
[General Accessories] dejannate:
Did someone know something about the Android 9.0?

I found today on Ali Express.￼
[General Accessories] Elibonbon:
Oh my god I think you've point why some of us are experiencing the upsidedown problem with the update 21052018.. If only they could send back the 21070617 firmware originally inside, maybe it could work.

I'm 100% sure this detail wasn't mentioned few days ago on the seller page ("Global Mi Homes Store")
[General Accessories] gordnnnn:
Crazy ****. That's new!!! But why there is a android 9 Version at this time which the old Version/Revision cannot handle?

I don't think they changed the Hardware at this point of lifespan. Especially when they start shipping the T2R MAX. Truly sad that the company makes things Like that so non-transparent. That's not customer friendly.

does anyone else want to contact wanbo? Or did we all got a new and other projector?😉
[General Accessories] Pralegan:
Hi! Can you please tell me how did you reach the settings menu? I can only reach an input switch, but settings button opens android settings!

aacoridng to this https://mobileai.net/2021/04/30/wanbo-t2r-max/

maybe that's new t2r max, new cpu and more ram amd slighly higher brighless (250 vs 300)
[General Accessories] dejannate:
Another photo from AliExpress. Android 9.0 on T2 max 1gb Ram.

Can someone find that firmware. Thanks.￼
[General Accessories] gordnnnn:
Yes, i'm also interested in installing the firmware. You think it will work on the android 6 Version?
[General Accessories] dejannate:
I think its the same version T2 max that we all have because on the picture said that The projejector has 1gig of ram. The newest model has 2 gig ram. So this Android 9.0 is probably for projector with 1 gig of ram. Only thing is how can we find this firmware.
[General Accessories] gordnnnn:
Yes you're right. The successor wanbo T2 R Max also looks very different. This Version MUST be for our T2MAX.

But to get the firmware will be very hard. This here is the only Thread about the wanbo. I can find only a few sites more, and to get it from there seems Impossible to me.

I will try to send a Email directly to wanbo. Maybe it will help. Otherwise i had no more idea.
[General Accessories] dejannate:
E-mail sent to all that i can find in wanbo. We will wait now. Hope that someone in wanbo will replay.

Who has a working projector

Please upload the file here

system\build.prop
[General Accessories] Mushulay:
Hi,

I am very happy with the wanbo, I got it about 2 month now and it runs smooth with zoom on. I use it only via hdmi input and use android only for the 4 corner keystoning. I'm running firmware 21052018, resolution set to 720p, 1 background process and animations off, no WiFi or Bluetooth enabled. With the resolution set to 720p, you can view media in 1080p via hdmi, only thing to be aware off is to set the input device to 1080p otherwise it will recognise a 720p device and only show 720p. So ensure to turn off automatic resolution. I use either ps4 or fire stick as input and have no problems with stuttering even with zoom on and 4 point keystone.
[General Accessories] SamTarly12345:
Hi! I flashed the firmware and had the same issue of a mirror inverted projected screen that I can't fix. I'm buying a new one with the Android 9 OS that will arrive over the next few days. I'll share the build.prob file when I get it. Let me know if there's anything else from the Android 9 OS that would help. Thanks.

hello everyone !!

I have the wanbo t2max since a few days

mine came with android 9 and I'm just seeing the whole issue that has been done with the firmware.

is there anything i can help you with ?? I haven't done anything to it, just check the system update

additionally, do you know if there is any way to get 5.1 audio out of the wanbo ??? (for use with a hometheter)

=)
[General Accessories] gordnnnn:
Hmmmm....it says you got the Modell T2 not the T2+ ..... Thats kinda mysterious.

Here is my answer from wanbo. The message could not be delivered 🤣🤣🤣
[General Accessories] sad_janus:
I don't know if that's how they mention the label above, maybe on firmware android 9 only say "T2" now??

this is mine label

i also installed 3 diferents apps from play store (DRM info, AIDA 64, and other),, on the 3 shows 1920 display.

in the native wanbo youtube app show FullHD too.

Hi! Here's a working from vendor Android 6 build.prop (i renamed it to txt to be able to attach it here; note its not android 9). I looked at the differences between my laterally inverted (mirror image) build.prop and this one. My guess is that the persist.sys.trapezoid_enable needs to be changed from 1 to 0 though there were quite a few differences. I hope this proves useful to some of you.

I'm having trouble figuring out how to root (or even use adb) to edit the build.prop. Newbie. Any one able to help? Thanks & cheers!

[General Accessories] firecough:
Hello, thank you for the firmware. I had my hopes up but it seems it's even worse now. Currently its now both upside down and inverted, the flip options do not change anything at all. When I click on a flip option, the screen just jiggles and bugs out to the same position. What can I do now?
[General Accessories] Elibonbon:
Ok done for me and it fixed the problem !! @MrBull3t21, I definitly thank you for sharing the solution and give me back my Wanbo !!!
[General Accessories] firecough:
Hello, can you please mention the exact steps you followed? I also updated with the firmware but now its even worse.
[General Accessories] MrBull3t21:
You can contact Mrs. Linda with your serial number under your projector. Her mail address is linda@szwanbo.net. I think she'll find a solution for you as well.
[General Accessories] MrBull3t21:
You can follow this steps. I've done with that way
[General Accessories] firecough:
Should I remove the USB after the update with the blue screen is done? So when blue screen update is done it turns off, and then you turn it on to update android, should the USB stick be on during the android update process?
[General Accessories] MrBull3t21:
After blue update screen is finished projector will turn off then you can restart without removing usb. It will take 4-5 mins to turn on after update, you can remove usb after projector fully started.
[General Accessories] Elibonbon:
Well, on my side I've

- downloaded the file,

- formated the USB key to FAT32,

- Copy/Past on the USB key (32Go),

- Removed the USB key informaticaly speaking by clicking on the option in the task bar

- With the projector unplugged from electricity, I connected the USB key

- Plugged the projector and press 10s on the power button until the LED blinked red/green

- Waited until the projector turned off by itself

- Removed the USB key

- THEN ONLY turned on the projector without the USB key

So android was quite long as usual after an update, but now everything is working pretty nicely.

If You are unsure how to use ADB connections maybe You shouldn't practice on Your projector...

Else there are quite few how-to's both here on XDA and on Google/Youtube.

Hi, Since you have the Android 9 version, you don't need to install 21070615 firmware. The firmware is for Android 6 versions and espeacially for flipped devices after installing firmware 21052018.
[General Accessories] Mizhelrg:
could you give me the steps to change to 720p?

it is done with pc, the developer mode is activated, it connects to the pc and the adb shell is started, the command to change the screen is entered and that's it?

is what I understand in the tutorials I have seen 😭
[General Accessories] nohaoo:
This is how to remove built-in apps but you can also change the resolution with this command instead.

adb shell wm size 1280x720

※ Default : 1920x1080

Hope this helps.

How You Shure it's real 1080p? I don't understand, if You configure the projector at 720p a more resolución input no looks like rescale 1080i?
[General Accessories] Mushulay:
After changing the wanbo resolution to 720p up, I started watching a movie via fire stick and you could see straight away that the resolution was reduced. I checked the settings of the firestick and the resolution went a automatic to 720p. I set it manual to 1080p. Starting the movie again the resolution was way better. I use a 100 inch screen so the resolution difference 720p to 1080p is quite easy to see. 1080i does not make any sense since the projector thinks it is 720p and the performance would most likely drop considering the extra work for the wanbo. Using the laptop as input, mirroring the display and comparing the display with the projector, small text etc are displayed sharp 1080p, certainly not 720p. Again need to set the output manually to 1080p.
[General Accessories] raezchavez:
Thanks! it was the information I needed. I had already done the rest of the processes through ADB, I hope I can do this step independently without failing.

The Chinese firmware seems no problem with zoom or trapezoid corrections and stuffs... Netflix is smooth too (installed via apk sideload), I uninstalled or disable most useless stuff and use TV Launcher, however I cannot find a working Miracast nor Chromecast app.

One Miracast sink works but only 10-min and requires Google Play to in-app purchase, which the Chinese firmware cannot. There is a bit delay / stuttering but not too bad.

Netflix on device playback is perfectly fine.

hi can someone help me? the image the projector creates is a bit off center and the bottom and the right side of the image is cutt off. like i can only see half of my start button when i use hdmi. is this normal? and is there anyway to fix it without the keystone stuff? i can see faint grey area in the top and left side, that if i can center the image a bit more will fix this weird cutt off issue but i have no idea how to do it.
[General Accessories] d3xtral:
nevermind updated to the 2107xx firmware and its perfect now without the stupid resource hog zoom
[General Accessories] Neto_aoseudispor:
Did you disable any other apps? I made the ADB commands and they worked. The projector actually works in 720p and via HDMI at 1080p, but the fluidity difference is still very large.
[General Accessories] Mushulay:
I don't think I did anything else. Did you set 1 background task via ADB? If not the projector is always resetting to default with every restart, I have pretty much just followed the setup they recommended on the Korean site. (LINK posted on the first page)
[General Accessories] Neto_aoseudispor:
Yes I performed all the commands. And keeping only 1 process helped a lot. It starts and maintains these commands, wonderful! But in my case I still have the gagging with zoom enabled.
[General Accessories] Mizhelrg:
someone already tried this ?? if it solves the lag in the games

Yes. Without zoom activated my Wanbo is perfect! But when activating the zoom or any keystone correction, the gagging starts…

Hi everybody! I recently purchased this projector and I'm very pleased, however, the image in the default position appears tilted, with the right side higher than the left.

For those who have old international units of T2 Max Android 6 with no issues on 21052018, have you tried installing the newest one (21070615)?

Or 21070615 is only for those who has flip issues on 21052018? I'm curious on the changes on the newest one. Since we cant upgrade to Android 9 due to hardware changes

[General Accessories] Neto_aoseudispor:
I updated to this latest version from May. I had the inversion problem.

As I have saved version 21052018 on my PC I ended up going back to it. I did the ADB commands again and to my surprise the gagging decreased a lot with the zoom activated using HDMI!!!

For some reason when updating and going back to the previous version the commands had a much better result! I'm thinking about overlocking it now to see if I have even better results…

One difference I noticed is that when using the Keystone correction the screen background is in blue color instead of black (I'll try to attach images for better understanding).

I accidentally installed a firmware which my device already has a Global version. Now the problem is my screen becomes upside down and flip. I have tried the Flip setting but does not respond at all. Everything else is fine. I even tried to factory reset but it doesn't reset the display.

Can anyone help please?

Thank you
[General Accessories] sheppanator:
Hi everyone, I'm trying to use my T2 with a chromecast and sadly there is no remote control codes for using the google remote to control a Wanbo brand device. Does anyone have an educated guess on another (maybe chinese?) brand that has remote codes that might match this projector? Alternatively, if anyone knows how I could enable HDMI CEC on the T2 FREE... this would work too, but it seems that this feature cannot be enabled in the limited T2FREE menus and is only on the T2MAX. Maybe there is a T2FREE firmware update out there somewhere?

Then just out of curiosity I have found a lot of conflicting info about T2FREE vs MAX in terms of the projector brightness. The website I bought from claimed they were both 150ANSI lumens, (the newest model that was native 1080p), but I have seen others that say 200 for both, and one that says the t2max has 250 and the free only 200.. Does anyone have reliable specs from maybe the manufacturer? It would have been worth paying the extra 30€ for the MAX if it was brighter, but I thought they were the same at time of purchase and didnt need the built-in OS.

Finally my T2 seems loud, I am getting a reading of about 55-60db in front of the device when its been on for 10 minutes, curious is this the same for the MAX?
[General Accessories] dejannate:
Try installing previous firmware. The latest firmware is for those who has already screen upside down and flip. Try downgrade firmware.
