Wanbo T2 Max (Android 6.0)

[MrBull3t21]

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?

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.

Hello, can you please mention the exact steps you followed? I also updated with the firmware but now its even worse.

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.

For those who suffer from upside down flipped and mirrored image problem i just contacted with Mrs. Linda and she sent me the 20210706 version and this solved my problem. I hope it solves your problem too. I'll leave link and attach the zip file also.

The Version Number is smaller than the old one. (21052018) so it seems this is a downgrade? Or does this Firmware do anything better?

Please can you ask Mrs.Linda to sent to you the android 9.0 firmware so we can all try that version. Can you please ask her is android 9.0 firmware compatible with every Wanbo T2 max model. Thank you very much.

Instructions are on the GitHub page and worked OK for me.

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.

I managed to run the ADB commands. All working. But the lags had the zoom enabled… As soon as I can, I'll try to do the steps I could and post here…

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.

 

[Mizhelrg]

Hey guys, just tried something new.

I used ADB Shell over wifi to change the projector screen to 1280x720 and also with zoom settings on and external hdmi device (Amazon stick tv) there is no lag I'm really satisfied with that, and the resolution on the Amazon stick remains 1080 without loosing quality.

Let me know what do you think

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

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.

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.

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?

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.

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.
