Anybody know how to extract boot.img from this ROm with Payload Dumper Tool ? I tried but i can`t.
Which rom are you using?, I have version 14.0.691 ST installed, I have not received anything yet, I tried to connect with a vpn to Beijing but it did not update either
You could download the update file above and follow the manual method to update yours.

I am very interested to convert it to run Win11. Anyone tried or having reference for possible method to do so?
I think this is too dangerous to try... delete for protecting us...

This now works with the latest update (14.0.820), it's a pain to change users but at least you can have multiple.I've tried launching the multiuser menu (com.android.settings.Settings$UserSettingsActivity) with "Activity Launcher" and it doesn't open
Why are you so ****ing happy?Nope. Just nothing new or discovery so far for our tablet...
It is your choice to be happy and enjoy with the tablet
.Or being sad and poking others with envy feeling.
I don't know if Lenovo checks this forum, but my biggest issue is the fact that the tablet doesn't connect to my 5ghz ssid/wifi/network name. I really want the tablet to receive higher internet speeds, but alas I've tried resetting and it doesn't fix it. I'm highly confident its a firmware issue, because I've tried resetting (it works in the beginning, then functionality goes away after an hour and never works again) and updated to the latest version, but alas nothing has fixed it. I know the tablet works with some Chinese wifi channels, but I wish they can just update the firmware, so it can work with USA wifi channels. I'm pretty sure I bought the international version, so maybe a firmware update can fix its compatibility. If you read this Lenovo, then thank you for reading our concerns.

2I find something to get PCmode back in Zui14 , I tested it , it's ok but I can't use my pen in pcmode (but when I back to normal , I can use it)

How is your PC mode different from what was on the first page of this discussion? https://forum.xda-developers.com/t/zui14pcmodeswitch-pre-release.4542445/1
Theoretically, this is possible if you follow the instructions of Xiaomi Mi Pad 5 from the Renegade Project, but I see no reason to look in this direction. The main thing is to make a backup copy of all partitions, or wait for the full firmware imageThank you for your dedication to write this article for us. Appreciate a lot on your work.
Could I request to load Windows 10/11 ARM image to our beloved TB138FC?

Frankly, I didn't feel much different but possible stability and more recent security update. -
