Cross posting to MULTIPLE new threads is bad behavior, especially when this should be posted to an existing debricking thread. I already answered your question in one of your other new threads.
The K4 has diags SSH built in. You probably flashed a K5(touch) partition to your K4, which is also bad behavior.
You should read enough to know what you are doing first... 
The official amazon updates use signed packages, with different signatures for different kindle models to prevent doing something like this. But with root access, you have a lot more freedom, including the power to SUCCESSFULLY do stupid stuff, just like you did. The download links are clearly labelled as to what model kindle they are for, but that did not stop you... 
Like I said in one of your other cross posts, you must recharge your battery and reflash the original K4 diags partition.
