Default [Q] Trouble updating kernel for Mokee MK44.2- i9300-140309-release

Hi, I just updated to MK44.2- i9300-140309-release. (DXEMB1)

On and off I will receive errors like

Quote:
"Unfortunately, Process com.android has stopped unexpectedly."
After checking the forum, someone wrote flashing boeffla kernel 2.1, I did and I got the following error:

Quote:
"Unfortunately, Process com.android.phone has stopped unexpectedly."
Then, I flashed boeffla kernel 5.1 and the phone bricked.

Sorry for a noob question, as I coudnt get my answer from the search tool.
