[Solved] ET30s projector does not work the keystone
I managed to download the update package, but the update procedure shown in the video does not work on my projector, the pendrive was formatted in FAT32, everything was done exactly as directed in the video, but in the end after holding the power button / turning off the projector simply starts, as in everyday use, and the screen showing the update being applied does not appear, please help. Attached is a video where I do the procedure and in the end I am not successful.
