Insta 360 RS New Software v.2.0 installation problem!

Hello! I can't install the latest firmware update version 2.0. All attempts are in vain! Has anyone been able to install the latest firmware update successfully?

The Firmware file that I wrote to the SD card does not see the camera when rebooting, nothing happens ((.. When I try to update through the Insta 360 (iOS) application, the following image "Checking Firmware" appears on the camera screen, and after reboot notning happens:

P.S. Firmware V.1.4.32 installed on my camera!
