Sorry if I was unclear, and thank you for taking the time to respond.
When you say "matching diags kernel", could you be more specific? I've seen the same advice in other threads, but it not obvious to me.
Going with the images on this link:

Would the correct procedure be to flash
kt_5.0.0-kernel_diags.gz to the
diags_kernel partition
and
kt_5.0.1-mmcblk0p2_diags+ssh.img.gz to the
diags partition?
I see that you wrote I should use the 5.0.1 diags kernel, but it's not on the list. Is there somewhere else I can download it from?
