In fastboot mode, do:
fastboot flash diags mmcblk0p2_ssh.img
fastboot flash kernel kernel-5.0.0.img
fastboot setvar bootmode diags
when my kindle reboot, it can't enter the diags menu , still show the big tree picture
It clearly says in many places, including the FIRST sentence of the first post in the simple debricking sticky thread, that you must flash matching kernels and partitions
. That INCLUDES the diags kernel. This is especially important when switching between 5.1.x and 5.0.x.
Do it! THEN report back here. Otherwise you are just wasting our time.
