MY Kpw4's FW revert to 5.10.1.3 from 5.12.2

I don't know if it is a special case or not,but I think sharing it is beneficial.Maybe,someone will learn something from it.

I JailBreaked your KPW4 using Factory JailBreak (Factory FW) from here.

But Updata fireware to 5.12.2, my Kpw4 lost JB,the";log mrp" do not work.
Before Updata,I flashed the newest ‘hotfix’ (2019-Oct-11 23:23:06)using ';log mrpi'. After the operation, I found out that it is a wrong operation. the ';log mrpi' has't work. But I can still perform the correct operation.
I flashed the newest ‘hotfix’ (2019-Oct-11 23:23:06)using "Update Your Kindle" to my kpw4. it work,but ";log mrpi" still don't work.Finally I put Factory JailBreak (Factory FW) in my kpw4 and update。After reboot,My kpw4's FW revert to 5.10.1.3,and ';log mrpi' work.
