First, what is the device? Is it an A/B device. If so, you should be able to find boot_a and boot_b in /dev/block/by-name. If not, it is unsupported. Is it brand new? If so, the issue might be that one slot is completely empty, in which case the solution is to install an OTA to populate the opposite slot. Otherwise, I'll need dumps of the relevant partitions. From here, if you want some additional context:

adb shell
su
cd /data/local/tmp
dd if=/dev/block/by-name/boot_a of=boot_a.img
dd if=/dev/block/by-name/boot_b of=boot_b.img
dd if=/dev/block/by-name/init_boot_a of=init_boot_a.img
dd if=/dev/block/by-name/init_boot_b of=init_boot_b.img
exit
exit
adb pull /data/local/tmp/boot_a.img
adb pull /data/local/tmp/boot_b.img
adb pull /data/local/tmp/init_boot_a.img
adb pull /data/local/tmp/init_boot_b.img

This happened when I upgrade a miui14 to Xiaomi hyperos. Because Xiaomi will wipe up the slot which equipped the MIUI14. My kernel flasher version is latest. And phone is Xiaomi 13 ultra.
