The first of those links is not clear if it applies to the K3 and contains multiple sets of change instructions.
Examine each file mentioned in the thread for the changes mentioned, revert the changes.
The second, depending on the version you used, would have removed the scripting required to run the un-installers mentioned.
Can you confirm what the results where of running each un-installer?
Can you confirm that each hack was un-installed?
Can you attach to your next post (don't use "quick reply", click the "go advanced" editor, use its "manage attachments") the script that you did use from the second link?
There was more than one version posted on (the now dead) gitbrew site.
Please include your answer to AZImmortal's question also.
