I am using armbian on TV box S905W. with 32gb EMMC memory. actually the free memory in my EMMC is about 24gb i.e. only 8gb. used
Currently, I have an additional box of s905w with the same version but with EMMC with 16gb memory.
I used emmc 32gb partition backup using dd command and extract to usb,
I use gparted to reduce the partition size ( ROOT_EMMC and BOOT_EMMC) to 12gb.
I copied 2 downgraded partitions to 1 16gb usb, repackaged it as an img file.
Proceed to use dd method to restore img file to emmc of 16gb device.
The recovery did not give an error, but after rebooting using the EMMC internal memory, the device failed to boot.
I want to know can we backup a device with 32gb EMMC to use on a 16gb device?
