Follow the Choidujour tutorial (the bit about getting BIS keys and mounting SYSTEM). I won`t repeat what is there, however, in brief:
1) Get your BIS keys. Use BisKeyDump for this
2) Download Hacdiskmount
3) Download memloader
Dump all memloader "samples" folder to SD root
Get your BIS keys - email them to yourself - or use lockpick_RCM or my Switchboot, which can do it for you and save them to a file
Run hacdiskmount, use BIS key 2 to activate "SYSTEM" - test your BIS key by clicking "check entropy"
Mount as a drive, browse it and delete files I said above. I haven`t really got time to do a full tutorial... But if you are unsure, maybe you should let someone else do it for you.
