Yes, chinese launcher has switch for zoom activation. If zoom is off, international zoom setting (trapezoid) in the system setting won't work.
[General Accessories] optionalmgrr.la:
can you post a screenshot? thx a lot in advance
[General Accessories] sklchan:
Just discovered that the cpu only can reached 1.5ghz although the governor interactive have freq range 1.3ghz-1.7ghz it seem the firmware limited the max cpu core speed to 1.5ghz...
[General Accessories] shim80:
Probably because of fan noises...

Hi, I'm a bit stuck.

I have a Chinese version of the firmware : WB-T2Max1080CN-V1.00-20201229 and I can't flash to the international version.

I have a 8GB usb key in USB2.0 format in FAT32. I paste the rights files at the root of the key.

Nothing happen when i plug it and press the button when the projector boot. It just boot normally.

Do you have an idea of how I can do that ?
[General Accessories] nohaoo:
You must press the button on the device. You have the latest chinese version and you won't be able to restore the version after flashing to the international ver.
[General Accessories] nohaoo:
Projection setting on the Chinese launcher
[General Accessories] optionalmgrr.la:
thx!!! I remember now!
[General Accessories] optionalmgrr.la:
yeah i'm surprised netflix worked quite ok on device, even though sometimes it struggles and there is a constant popup that shortcut menu is starting in the bottom right
[General Accessories] lemonial:
Did you keep pushing the power button more than 8 seconds?

Please try another USB flash memory.
[General Accessories] Supergupin:
I tried several things :

- press the button before plugging the power cable for more than 8 sec

- press the button when the power cable is plugged and the LED is red.

Everytime, the projector start as usual and there isn't any blinking LED.

I tried with 3 differents USB stick :'(

Do you think the best thing I have to do is waiting for a new international version?
[General Accessories] tuanharc:
You must power off -> usb plug -> press power button 10 sec

Hello,

This topic is really great, thanks a lot !

I have a wanbo T2 max with the last global firmware and there is a bug really annoying : the keystone is reset at each start :/

Regards

Edit : Nohaoo, the brightness is really really great. Did you change the settings ?
[General Accessories] nohaoo:
Hi! It depends on how to take a photo. It looks good but actually just usual.

This is my blog and I'm writing all things about Wanbo T2 Max. You will see other photos and they are not that good.

Is anybody having any audio lag over bluetooth? It seems to happen occasionally for me and I haven't worked out the conditions to replicate it properly.
[General Accessories] Chyril:
I noticed that yesterday when i connected a Bose Bluetooth speaker to Wanbo or to an Amazon Firestick 4K connected to the Wanbo (for which you have an option to reduce that lag)
[General Accessories] Supergupin:
it doesn't work

thank you to all for your answers. I wrote to the seller, i'm waiting for his answer :)
[General Accessories] nohaoo:
At first with original chinese firmware, with all bluetooth speakers, I had problems like lag and no sound. Then I have been only used builtin speakers so far cause they are not that bad. Today I just tried my soundcore motion+ with the international firmware again, it worked like a charm.
[General Accessories] LeFarfadet:
Thank you all for your help! Very useful !! Hoping for a correction for the Zoom ...

For the mouse, with International Firmware (20122420), I just have to maintain"mouse" button on the remote control for 2 seconds and it works !
[General Accessories] optionalmgrr.la:
Can you explain more and where can I find the latest version of international firmware??
[General Accessories] lemonial:
Does anyone successfully update the system version through OTA for either Chinese or global firmware?
[General Accessories] LeFarfadet:
It was delivered with this firmware installed. If anyone can suggest me how to extract this one, I can help... and no OTA update available in my T2Max.
[General Accessories] shim80:
I would like to see custom ROMs for this device...

Or maybe a way to switch the motherboard for something more powerful (like Orange Pi Zero 2)...
[General Accessories] optionalmgrr.la:
i wonder if we have to flash new version rom by power button method, it will replace everything and we need to setup each time again?

ota seems better but we don't know if ota will work.
[General Accessories] lemonial:
Firmware update will delete exiting DB including apps and configuarions. So you need to set them up from the scratch once update is done.
[General Accessories] sklchan:
I've rooted my device but nothing much can play with as the kernel kind of limited. Found out the ADB Debug through WiFi no need any extra app as previously suggested by other. Then just with these adb debugging remote command able to unlock the full 1.7ghz cpu frequency toward dedicated apps you have.

Below the example to unleashed the youtube vance to full 1.7ghz cpu clock. For any others apps that you have just add in their packages detail in the .XML file and update it using same method.
[General Accessories] sklchan:
1. Remote adb into your t2max

2. Type in below command:

su

mount -o remount,rw /

mount -o remount,rw /system

busybox mkdir /sdcard/SuperSU

cp /system/etc/cpu_dvfs_scaling_antutu_packages.xml /sdcard/SuperSU

3. DO NOT CLOSE your remote adb session!

4. Now using text editing app and manual edit the extracted .xml file with your package name within.

5. After edit completed, save and proceed with below command in your remote adb

cp /sdcard/SuperSU/cpu_dvfs_scaling_antutu_packages.xml /system/etc/cpu_dvfs_scaling_antutu_packages.xml

chmod 0644 /system/etc/cpu_dvfs_scaling_antutu_packages.xml

chcon u:object_r:system_file:s0 /system/etc/cpu_dvfs_scaling_antutu_packages.xml

6. Reboot your t2max.

7. ENJOY!!!

This is the mediatek cpu benchmark cheat code. So whatever packages name that in the .xml file will get cpu boosted while running.

I've out of idea what else to do to tweak our t2max now... 😀
[General Accessories] nohaoo:
Is it still stable after uninstalling mid.systemmenu? And no more popup mesaages?
[General Accessories] sklchan:
After checking DO NOT uninstall this mid.systemmenu.services as this is the long press side menu for the Picture,Color,Sound setup menu which I think is crucial for t2max as a projector.
[General Accessories] grunge888:
that’s so awesome! is it possible to boost the processor for the hdmi input? There may be a an id for it?
[General Accessories] nohaoo:
I guess the HDMI input app is com.mstar.tv.tvplayer.ui (MTvPlayer)
[General Accessories] grunge888:
Cool I will check once my wanbo arrives 👍
[General Accessories] Fabiogenk:
Exactly, MTvPlayer is the process for HDMI Input, i will try to boost the cpu for it :)
[General Accessories] bonobogaming:
I connect my T2 max on my AV amplifier that i connect my chromecast/PS4/Recal box but all sound output are goign out from my T2 speaker instead my AV amplifier .

Is there any way to use my 5.1 system of my amplifier system?
[General Accessories] Fabiogenk:
I think it can't reproduce 5.1 audio, but i'm not sure.
[General Accessories] nohaoo:
A korean user also having same experience. It seems that the latest firmware with iQiYi launcher does not work of USB firmware update by long press power button.

He even tried a USB update in the setting using International firmware (bin file) by changing the file name then his T2 Max became a brick... I really want to help him restoring..

iQiYi looks like this.
[General Accessories] Supergupin:
I have exactly this Launcher. If you find a solution, please tell me. I will do the same if I find something.

Thank you :)
[General Accessories] bonobogaming:
My bad my issue was just the fact that i have forget to enable HDMI CEC/ARC in the T2 max config menu.

Other question :

Any possibility to boot on the hdmi directly (instead smart tv menu)?
[General Accessories] corass:
As far as I know, the chinese laucher (on prev pages) could do that. Just change it for this purpose, do it, change again for your launcher.
[General Accessories] sklchan:
So far I'm impress with this projector, after some tuning and run some performance test in youtube below what I've got...
[General Accessories] nohaoo:
Does it mean good? What have you done for the tuning. And what about the zoom status?
[General Accessories] Aw2006:
How do you guys go to developer setting. I don't have a setting icon and "about system" don't give me android build. Only mac address etc

Happy cast app got lots of bloatwares and spam. Need china phone number to register....

Downloaded other browsers kept crashing. Only YouTube Vince work for me and chromecast.

But only their default china app streaming seems to have smooth video playback
[General Accessories] sklchan:
Yes, good enough for the price as well very reasonable performance as a projector.

Theoretically zero frame drop with 60fps fullhd video... 👍

[General Accessories] Zinyth:
In my case, the video is very slow when using keystone (zoom on), both on Chinese or Global firmware, with a firetv.

This is way better when configuring fireTV Output to 720p, but still slow.

I activated the CPU usage in developer menu, and saw that logd is consuming a lot of CPU usage (most of it is taken by trapezoidServer...). Stopping logd seems to reduce video problems (adb shell stop logd).

It's a shame there's no way to watch a smooth video with decent resolution...

I don't know if it's better when playing directly from integrated android : Netflix does not start (not licenced! ?) and primevideo does not play movies (error). Any ideas ?
[General Accessories] nohaoo:
You may try some apps like launch on boot. APKpure shows many related apps. I tried 2 of them and they worked but launched with very long delay as 20 seconds...
[General Accessories] NasraFr:
Hi,

I've bought this little Wanbo, and i have some problem listed in this forum (some application like MolotovTV (french TV) have sometimes black screens, Nintendo Switch render on HDMI output seems to be very annoying (it seems to not be correctly synchronised on 60fps)). I need zoom setting (trapezoid) to have a correct screen.

I didn't make tests, it's just impressions.

I have the International One (blue interface), but i don't know if this is the latest version, or if the version discussed on this forum could resolve some of my problems.

Could you informs me ?

Thanks !

@nohaoo has a put together some nice articles on his blog: https://knowhowbank.tistory.com/
[General Accessories] drean:
I'm currently looking to get an affordable projector, to mainly watch videos (via HDMI from a PC), or directly from Amazon Prime/Youtube/Netflix; and maybe, it could also be hooked up to a game console for some gaming. Being able to cast from an android phone would be a plus.

Vertical *and* horizontal keystone (trapezoid?) correction is required. Where possible, i would like something that can work easily and smoothly out of the box, without tinkering with it too much

Would buying a current Global version of the Wanbo T2 Max from Aliexpress meet my needs? I was reading about how there was some lag (or dropped frames?) when trapezoid correction is used - has this been fixed, or is it still an issue?
[General Accessories] LeFarfadet:
In my opinion, it's horrible with keystone. This depend upon your requirements, but for me it is not acceptable to watch a movie with a fluidity problem (watching with Tivimate and Vimu in a Firestick).

It's really sad, because with zoom/keystone off and for the price, I love this projector. Even the sound is passable.
[General Accessories] nohaoo:
Trapezoid correction still not solved.
[General Accessories] optionalmgrr.la:
Did you find overclocking the CPU helps zoom correction speed?
[General Accessories] optionalmgrr.la:
how did you root the device?
[General Accessories] sklchan:
My projector wall mounted with exact location so no need the correction
[General Accessories] sklchan:
Fully manual through the remote adb command with some pre transfer SuperSU required apk/sh/so... not recommended for those who dunno what you're doing... 😅

Do you use Magisk after root or something else? I wiil try with pc and Kingo ROOT (via apk don't work).
[General Accessories] sklchan:
Nope as I've mentioned before, nothing much to do after root as the kernel limitation unless you wanna cook yourself a custom rom which i totally not into that... 😅
[General Accessories] corass:
Hmm, so just overclock CPU can be really useful? I want to root because mac.apk in international version don't work (can't change MAC address) and maybe that's why I can't update system via OTA? Hmm...
[General Accessories] clyevo:
Hi, is there any fix to zoomsettings being automatically reset every time on turning it on and off?
[General Accessories] LeFarfadet:
if you have the international version just update with OTA (press 5x on check system version)
[General Accessories] corass:
I've done 5x click model to OTA mode open. But when check version still said I've info that i have latest version. I assume thats because mac.apk can't change my mac :(

I've reinstall mac.app and mac changed but still no new version found on international (based on first realese)

OTA is only available with stock international version I think :-(

[General Accessories] ph324:

[General Accessories] Xocketeer:
Hi all,

I already have international version but it not clear to me what will happens once i do this in quote. I wan to know if the zoom setting switcf off i´m still able to make some trapezoid corrections in order to see the right projection.
[General Accessories] LeFarfadet:
No, with zoom setting off, video is smooth but u can't make any trapezoid correction
[General Accessories] Xocketeer:
Ok, i'll give it a try to the new chinese launcher. Thank you very much!.

Anyway, i'm still affraid of being unable to go back to the initial software situation. This picture is my actual settings. I need the "four Point scaling" because if i don't use it the wanbo's projection is so much bigger than my wall ( it´s placed about 3,30meters away from the wall). The other option named "infinitely scaling" it's useless from me because whit it i'm unable to fit the screen on the wal.

So the question is ...with "zoom setting off" in the new launcher from the chinese firmware i'll still be able to fit in the projection zone? And, its the answer is no... could i still get back to previous settings?

I don't want to make irreversibles changes because i'm "quite/moderate" happy with actual situation even thought i hate so much the lag video issues in many situation.

Thank for your help.

Note: My Wanbo T2 Max compilation number is 21010915
[General Accessories] LeFarfadet:
No, with Zoom off you can't use any settings for projection size. so you can't fit the projection zone.

but don't worry, you can download this launcher and then toggle ON/OFF for Zoom Settings, it's just an apk not a firmware ;-)
[General Accessories] Zinyth:
I found a way. first, activate ADB in dev mode and use an app to connect adb over wifi

Then

adb connect <@IP>

adb shell

su

#We need to remount the FS to modify a file (to apply parameters on boot)

mount -o remount,rw /system

#Backup the original file

cp /system/bin/init_preinstallapk.sh /system/bin/init_preinstallapk.sh.bak

#Default HDMI boot

echo "/system/bin/monkey -p com.mstar.tv.tvplayer.ui 1" >> /system/bin/init_preinstallapk.sh

#Shutdown

reboot
[General Accessories] Zinyth:
For those using the zoom mode, you can greatly improve CPU usage :

#Activate ADB in dev mode and use an app to connect adb over wifi

adb connect <@IP>

adb shell

su

#We need to remount the FS to modify a file (to apply parameters on boot)

mount -o remount,rw /system

#Backup the original file

cp /system/bin/init_preinstallapk.sh /system/bin/init_preinstallapk.sh.bak

#Save some CPU (a lot!)

#Need to disable zoom and reboot to change zoom settings

echo "stop logd" >> /system/bin/init_preinstallapk.sh

echo "ps | grep trapezoidTest | cut -d\ -f7 | xargs kill" >> /system/bin/init_preinstallapk.sh

#Change default resolution to 720p to limit stuttering with zoom on (if you want...)

echo "wm size 1280x720" >> /system/bin/init_preinstallapk.sh

#Shutdown

reboot
[General Accessories] Zinyth:
The sad news is that stuttering is not a CPU-related problem. I still hope a new firmware allowing to use zoom with no lag...

for pepole that come from the chineese version , they can't do the international OTA upgrade,

may be we can catch with network tools (like wireshark) the connection on a stock international version ota transfert, and capture the destination file (update.zip) and do the same manualy on the chinese version
[General Accessories] Coldieee:
I'm on International firmware version W073_DC.1080T2.Zeasn.21010915, when I check for updates and use adb logcat I can see that this URL is used when checking for updates (no updates available):

So I think we can visit:

http://media.toptech-developer.com:2300/rest/version/list?req={"proNameJust":"C003_358_RX1080"}

to get a list of OTA update files available. Current there is only one entry which looks like an update from W073_zeasn.1080T2.EN.20122420 to W073_zeasn.1080T2.EN.20123109, but that is not the latest version:

@Coldieee where and how, place json file on t2max?
[General Accessories] Coldieee:
You can't use the JSON file. It just tells you the URL for update files.

For example, to update from W073_zeasn.1080T2.EN.20122420 to W073_zeasn.1080T2.EN.20123109 you can probably download the zip file listed under swUrl and place it somewhere to update manually. But those versions are not the latest anyway.
