My k4 black was bricked after one month use.
I followed the instructions in Guide to debricking Kindle Touch v4 ， but got stuck when entering diags mode.
I used the images from pastebin, flashed all 3 images including diags, diags_kernel and kernel, but got black screen when entering diags mode.
I guess maybe these images are NOT suitable for k4 black?
