Thanks for your response.

Firstly, i have followed all the instructions on 'Kernel Power' and Jakimans wiki in terms of trouble shooting and de-installation. I dont have the Leaked PR1.2 installed.

whenever i attemp the apt-get for the kernels or reverting to stock i get the following

Dpkg: parse error, in file ‘var/lib/dpkg/available’ near line 1282 package ‘mp-fremantle-002-pr’:
