Thanks everyone, but in itskamel's tutorial it says
'Great your on 3.55 now download toggle QA by REBUG, install it via pkg files. Run the pkg, you should hear some beeps, now to confirm go to network settings and push at the same time L1 R1 L2 R2 L3 and down on the d pad. If the menu showed up you have successfully dehashed. DO NOT continue if you have not verified that the above step worked.
Yet the link provided doesn't work. Is this essential, and if it is, where would i be able to find another DL link?
