Awesome! Thank you very much, will try flashing the new firmware now

Edit: The flashing process went as smooth as possible. Doing a quick test there were almost no lag over HDMI. Thanks again @Jeffreylyr, used your color configs aswell and It was great! Very happy with the projector now!
[General Accessories] blackhawks1211:
Hi, i just want to know, if this is for TVOS or Android version? Thank you
[General Accessories] Jeffreylyr:
Hi, im not really clear what you mean.

The only versions that differs for a T2 Max are

1. Android 6 variant

2. Android 9 variant

My Wanbo T2Max is international version:

Wanbo -> Firmware 16062022 (For bug fixes/features)

OS -> Android 9 (For Android based ARM processors)

Build -> TVOS 04.16.031.01.12 (For AndroidTV experience)

The OS & build are just operating system which is not really upgradeable unless you root or manually force upgrade both the OS version (Do at your own risk, may brick/break device) .

On default, the projector will have:

1. Whale_Tv launcher as default homelauncher, stock AndroidTV playstore as per TVOS requirement.

2. Google services enabled, Google apps, netflix as per International version default apps.

Firmware updates are always rolling in for Wanbo (e.g for bug fixes, new features). The one i uploaded is the latest 16/06/2022 firmware updates as i know off. My previous version prior to this update is 26/09/2021.

There are also two more updates in Oct 2021 and March 2022 mentioned somewhere in this thread, but i did not update to those at all.

However, you might want to note that this firmware/software update might be strictly built for international version, Android 9, 1gb ram, 16gb rom variant. If others, im not really sure.

Hello!

Is your projector the t2Max described t2+ max?

I'm not able to update my projector.

I do the whole process, I've tried with 3 different pen drivers and I can't.

Could someone make a video teaching?

Thanks
[General Accessories] Jeffreylyr:
Hi,

t2m+ or t2max . they are the same.

Please make sure that your projector is:

1. international variant (with google services)

2. Android 9 with TVOS variant

3. 1gb ram/ 16gb rom model

4. Not at the latest 16062022 firmware

And could you tell me which part are you stuck at?

To flash/update (safest way if my prev method dont work):

1. If possible, use an old thumbdrive that only supports formatting to fat32. Download the file, extract all 5 items and put in that thumbdrive. You do not need to try other thumbdrive if you are sure that your thumbdrive can be read by Wanbo. To test, just plug it in when Wanbo is on, there should be a popup to read external usb. This means that your fat32 thumbdrive is formatted correctly and readable by Wanbo.

2. You can try to change the boot mode to default (instead of HDMI or Memory). Unplug USB, HDMI, AUX.

3. Turn off wanbo using PHYSICAL button, turn off socket. unplug power cable on the Wanbo side. At this point, there should be nothing plug in to Wanbo

4. Wait for the red light behind wanbo to dissapear to ensure you flush out remaining "power" in the capacitors.

5.. Plug in thumbdrive, plug in power plug on the wanbo side. Turn on socket. The fan in Wanbo will run awhile, but ar this point the wanbo SHOULD NOT automatically turn on. Wait for about 10 seconds.

6. Press and Hold the PHYSICAL power button on top of the wanbo for at least 10seconds. !!Do not use the remote control power button!!

7. Update screen should appear.

If you see "Wanbo" follow by Android" means it failed. repeat from step 3 after it boot to home screen.
[General Accessories] andresousa.com:
I found out what happens. You told me if my projector has a TVOS system and found out that it's just an Android projector. That's why I miss many things that users report here on the Forum. How do I install an Android TVOS on my projector?
[General Accessories] Jeffreylyr:
Could you show me some photos so that i can help you ask the support side as well?

Photo of what is the processor of your Wanbo T2max projector? Download DRM info and take photo.

- Mine is Mediatek's MT5862 . These type of processor chips are usually found in smart tv ( android smart TV) . But for Xiaomi Wanbo, it is a smart projector with Android TV

Photos like whats your home screen look like ( i read your previous replies in this thread, you mentioned yours is like an android handheld device) ?

Photos like your projector settings page (If you have)? Else how do you access projector settings like zoom, Picture , sound settings?

Take a photo of the sticker at bottom of your projector as well..
[General Accessories] andresousa.com:
Thank you for your help!

I could not find this processor information.

I made a small video for you to see my configuration as it is limited.

Complicating contacting technical support is that we have a difference of 12 hours. I'm in Brazil, and they always answer me at dawn.
[General Accessories] Jeffreylyr:
I realised that yours is just android without tvos. means the native MT5862 processor without any TVOS built on it.

Searching the old replies, i found this link shared by someone. It seems to have updates specifically for mt5862. The one i highlighted is the nearest one i can find for your version.

Your projector version is " eng.huab.20220312.131717" , whereas the update i found highlighted in the picture is for "eng.huab.20220312.141140". It will update to "eng.huab.20220722.210903".

The update content description is "Optimize some user experience".

Do you want to try this? I have attached the zip file here. Maybe you can try to see if this works.
[General Accessories] andresousa.com:
Cool, where did you find this update?

I really want to update mine to see if it has a better performance.

My Xbox and Chrome Cast 4k they don't identify as 4k :-(

I think I'll take the risk and do the update.

Would you do the update?

I contacted Wanbo support as well.

Let's see what they answer me

Thanks a lot for the help!

Hey, wich APK did you use to get access to developer options in Wanbo T2 Max?

I'm runnig "T2MAX-Z9-EN-20220616", and installed the APK "LM (ATV) - 1.0.4.apk" but it don't show the developer option shortcut.
[General Accessories] Jeffreylyr:
You do not need apk for this.

Go to settings > about Projector > Hold "ok button" at the version option.

Developers option menu should pop out from the right side
[General Accessories] Danyl_o:
Thank you, it worked!

Did someone here manage to fix the frame loss through HDMI?

I did it everything that a read here, but nothing have changed.
[General Accessories] Jeffreylyr:
No worries.

By right this latest update should have made the Wanbo T2Max projector dropping frames much lesser than before.

It should be butter smooth(low delay) and frame drops should not be very noticeable unless you put a 4k 60hz monitor beside your projection screen.

Anyways, you can try this option:

1. On Wanbo side. Go to settings > look for the settings to change HDMI EDID > set it to 2.0

2. Ensure that you have a high speed HDMI cable(2.0/2.1) from source to projector.

3. On Source side. settings > desktop/screen resolution set to 1080p60Hz OR 2160p60Hz

Unfortunately despite all, Wanbo T2max Default built in Resolution is 1080p@50hz. But by eliminating factors such as EDID 1.4 or AUTO EDID , it will help to maximise its potential.
[General Accessories] Danyl_o:
I did what you said, and I set my chromecast as 1080p50Hz, now I'm only able to see the lag problem when the projector is showing something that fill all the image, like a landscape or a drone footage, otherwise is pretty smooth.

I hope Wanbo release a new update soon, something with an overclock or something more light.

I really would like to install some OS like "Wanbo T2 free" and get rid of the "smart" part from this projector.
[General Accessories] Jeffreylyr:
I see,

i am not an expert on this. But perhaps there might be a possibility that the chromecast wifi signal is not as strong. This is also a factor to frame droppings for streaming contents.

As i do not use chromecast or Xiaomi stick etc, i might be wrong. But all i could say is that hdmi from my desktop running at 4k60hz (2160p) doesnt drop frames as much and have bearable response delays (maybe 30ms or so), typical monitor is 1~10ms delay.

Agree, they should release a budget Wanbo T2max (non-smart) variant Instead of WanboT2free with lower native resolution.
[General Accessories] Jeffreylyr:
can have a look at my response for another reply

Is it possible to install the "XMing Mini Q1 SE" OS on the T2 Max?
[General Accessories] xavierkira:
I've updated to the latest version of the firmware, but when I tried to change the image settings (brightness, contrast etc.), the changes doesn't reflect on the image. I've tinkered with everything but the image just remains with the stock brightness and contrast.

Any solutions? or any people out there facing the same problem?
[General Accessories] Danyl_o:
Wich is the file name of your update?

I had this problem too, but when the projector was restarted the changes appeared.
[General Accessories] xavierkira:
It was the June 16 , 2022 firmware. If I'm not wrong I've already in this version when I bought it, but I tried updating after the display settings did not reflect even I've made changes.

After updating the problem still persists.

Tried restarted the projector and the issue is still there

Hi !

I have a bug which occurs with an HDMI device like Fire Stick by Amazon !

Iet me explain in detail :

For some reason, when i start my fire stick TV the signal drop randomly until the screen softlock on "no signal" !

I'm forced to unplug the HDMI cable and reconnect it but after that the sound doesnt work at all and the signal still drop.....

The new international version doesnt fix the problem....

Anyone have a tips to fix this ?

THX !!!!

Do you know if there is a new update available?

My version now is "T2MAX-Z9-EN-20220616"
[General Accessories] Danyl_o:
Hey, can i use adb to make a little overclock on the projector in order to get more performance and fix the "frame loss through HDMI?

Or

Is it possible to install the "XMing Mini Q1 SE" OS on the T2 Max?
[General Accessories] Danyl_o:
Hey, about the sound you need configure your Fire Stick as "stereo" the T2 max doesn't work with "sound surround".

I didn't had this HDMI signal loss problem, but I think that you can set de HDMI port on the projector as "2.0", the "automact" option isn't good (I'm using Chromecast 3).

I really recommend you to return your T2 Max if you still can, this projector is the worst that I ever had.
[General Accessories] Danyl_o:
I have this problem too, while using chromecast through HDMI, the only thing that minimize it, is:

- Turn off all the keystone correction and zoom.

-Turn on "force 2d rendering" on the developer options.

This just minimize the problem, make T2 max more usable.

I really recommend you to return your T2 Max if you still can, this projector is the worst that I ever had.

Hello all,

For some reason I cant seem to update to any firmware that was sent here, using the usb stick method.

My current version is 9.0.0-RS-20210928.1224 from september 28 2021 and the build is eng.huab.20210928.122327

Does anyone know why or have a firmware that would work and solve the zoom lag using hdmi?

Thanks
[General Accessories] Danyl_o:
Hi, about the firmware version, my version is "T2MAX-Z9-EN-20220616" and to update, I just unzip it in a usb stick, and just plugged the wanbo on the wall ... I didn't pressed any button, just waited ...

About the lag through HDMI, it get's better on the last version, but only if you turn off all the zoom or keystone option and turn on "force gpu rendering" in developer options.

But the lag still there, much better, but if you pay attetion, you can see that still therer.

I finally changed my projector!

I sold it to my friend T2MAx and got a T2RMax 2gb. Can anyone tell me if there is any update for the T2R max 2gb? Do we have an exclusive forum for him or can we talk in this one?
[General Accessories] Tanumand:
Hello guys.

I just bought a t2 max recently and everything is working fine, But after 2 days WIFI stopped working and won’t switch on! I did not anything special with my t2 at all. Installing 3 application via google play and enable accessibility service for button mapper is the all things I’ve done. Factory reset does not help either. It’s funny that this the 2nd time this matter happens to me and the 1st time I use my warranty to replace the projector with a new one. This is not logical happening this problem once again! It would be nice of you if you please help me with this situation🙏
[General Accessories] Tanumand:
Hello my friend,

I had an issue after enabling usb debugging and connect to my projector with adb WIFI to enable accessibility service to use button mapper. after restart my WIFI seems to be disabled and no chance to reactivate it by changing usb debugging and developer option settings. By the way there is no wireless debugging option, it just usb debugging . Also try to factory reset. NO CHANCE. Please help.
[General Accessories] Tanumand:
IMPORTANT

I want to share my experience to all of you in order to avoid any problem for your t2 later:

1- Do not enable developer option, neither usb debugging and connect via adb wifi to do anything, It will disable your wifi after next bootup and no chance to enable it even factory reset. Only solution is to reflash your t2 ROM.

2- Flashing process is too simple. Just download the proposed rom in page 2-3 and decompress it to a fat32 formatted flash and unplug your t2 power supply and put your flash on and replug power supply and WAIT ONLY 10 SEC, DO NOT ENTER ANY BUTTON JUST WAIT. It will upgrade itself. But remember its risky cus if you loose your power while upgrading you will brick your device and its very hard to rescue it.

3- Remember this as a very sensitive projector and has a very sensitive software, I do recommend you not to try to modify or change its settings a lot, You may face problems. Just connect to wifi sit tight and enjoy your movies.

If you want more detail on above matters you can find me through whatsapp +9893798014145.
[General Accessories] n3w0rk:
I already have said it on the Tutorial.

Note: Once Wireless Debugging is active, your WiFi will stop working on next reboot (Be sure to de-activate it again once you're done.)

Disable USB/Wireless Debugging and restart your device and your WiFi will work again.

Does anyone got any new firmware yet?

[General Accessories] ChrisRed:
Hello, I bought a T2Max Android 9 and at the beginning it was working very good only some delays sometime on the bluetooth sound. I noticed that my firmware is from Nov 15 2021 so I texted to zhengjiahua@szwanbo.net and gave me firmware 20220407 with no success on updating. Send me some other firmware and no success at all.

I tried to find an update trough that list that someone uploaded here before http://media.toptech-developer.com:2300/rest/version/list but nothing worked, all of them are aborted on the bootloader cause my build is MStar/eng_wwt/eng_wwt:4.4.4/KTU84P/2.0.13:userdebug/test-keys

The person from szwanbo insisted on factory reset my projector. I'm using projectivy launcher and I reset the Mediatek settings (that was dump i guess) after that everything is reddish except launcher and youtube. HDMI connection red tinted, videos from USB or internal memory reddish, Netflix is reddish. I don't know what to do....

Can anyone help me please?
[General Accessories] ChrisRed:
So, I put a firmware from the list above it installed it but know it doesn't open. It stacks on Android logo loading and restart by its own and it is upside down......

[General Accessories] GOODvinD:
Hello there, I have Wanbo T4 and I believe it has the same firmware as T2, nevertheless I made a dumb thing and got into aging mode. Now I am chatting with the support guy and he sent me firmware update, but after all the updating was done successfully the aging mode still kicks in after rebooting. I've managed to partially control the projector with PC mouse, but the thing is it can only be used to click and move cursor and no "return" (go back)... so I kinda going to settings - change it - reboot projector - going to another setting - change it - and so forth...

Do you have any Idea how I can get rid of this "aging mode"? Maybe a factory reset in projectivy? (though I haven't found it yet)

_____________________

Edit: The support guy talked to an engineer and gave me a button combination that turns off AGING MODE

The combination should be pressed as soon as RGB screen appears after booting. Combination is : MENU (tree stripes) -> RETURN -> POWER BUTTON.

_____________________

And viola your projector is back to normal!

Hope this will help for others who are eager to mess with factory menu :)
[General Accessories] Jeffreylyr:
Hi all, great news again. Just emailed the support for a "fake problem (lagging video playback)" in hopes of getting a newer software update..

So the guy replied with a new firmware.

Previously, i have uploaded a June 16, 2022 firmware sometime in July in this thread.

This new update will bring the firmware to 20221117 ( November 17 , 2022 ).

I have uploaded the new firmware update below. Please give this post a like if it work for you ! ty

[Download from any ONE of the 2 option will do]

2. The Attached file in this reply

Ill made another post regarding "new" things that i have discovered from this new update.

Like before, the flashing procedure is exactly the same. Ill copied paste it here again.

( Do note that once you update, all existing applications, data, system settings , colour configurations will be erased. Saved them if you need)

To update Wanbo to November 17, 2022 firmware. Same steps mentioned in thread:

>>>

1) Downoad file , Extract/ Unzip/ Unrar , Paste all 5 items inside the file in a Fat32 thumbdrive

2) Turn off Wanbo , Turn off socket + Unplug power plug on Wanbo side, Plug in thumbdrive

3) Plug in power plug on Wanbo side , Turn on Socket. Wait about 10 seconds for update screen to appear

4) Update screen appeared , let it finish

5) Once it boot up again, It will stay on "android" screen for a while. Just be patient and let it finish :) Cheers !

-- ELSE if boot to home page, repeat procedure starting from step 2
[General Accessories] Jeffreylyr:
Regarding the November 17 , 2022 firmware update

New things i have noticed:

1) Additional Screen saver option in common settings

2) Additional screen resolution information in AboutProjecter

3) A shorter name for the firmware version in AboutProjector

4) Additional Timer option in common settings (iirc it wasn't there previously)

5) Edit picture settings (brightness etc) work in real time now for running applications (youtube, spotify etc). Home launcher no effect

6) Built-in Youtube 1080p 60fps video playback is much much smoother. Unsure about media playback from file, chromecast stick, firestick etc. Still couldnt get 4k videos though.

7) HDMI Input latency is greatly improved! Literally couldnt tell the difference. maybe 10~30 ms delay which is typical.

8) Brightness setting now scales properly and control the backlight properly. You can do 80 and wont get an overly exposed screen.

9) Contrast settings also have a little tweak. Reommend 48~55

Unchanged:

1) Youtube Vanced still does not get installed properly ( error: Problem parsing package). Alternative - SmartTubeNext / SmartTube

2)

To Test (To be updated):

1) Killing of background application randomly

2)

Attached: Video 1080p Ultra preset Fh5 short intro gameplay. A little stutter at the start (i believe is my pc problem lol) , overall it is a great improvement in terms of latency and "frame drops" through HDMI. You'll notice a screen refresh horizontal line going down nearing the end of the video.

Attached: Picture of 1080p smart tube video. As you can see the UI/BOOT resolution is now 1080p 60fps :) unlike the June update which is 1080 50fps
