@mtcl11 The firmware has been released, but has not been verified by the tester. If you need it urgently, I can give it to you first：https://dl.khadas.com/products/vim4/firmware/android/vim4-android-11-64bit-v220812.img.xz
I have only installed firmware using owowoo, are there instructions to install it after I download it? Like just use etcher and install it on SD card?
Do you know the steps to burn this image? When I use etcher or Rufus it says this is unbootable image.
Can you provide any li k or documentation on how to install it either on emmc or on SD card to check?
