Error in twrp recovery, what to do?

Question

Android

I did wipe, through twrp, Cache system Davlik Data, after that I started flashing the system.img image (1.8 GB), and I got an error: The image size is larger than the target on the selected device. The size of the internal memory is 3.8 GB.
I flashed boot.img, the size of which is 11 mb, and ended in success, I mean the boot firmware, but the main system image was not flashed.

turned out to be 1743 mb, and the firmware image was 1800 mb+, fuhhh) thanks for your attention!
