You can't compare it with Memchunkhax2 because Mch2 doesn't support sys version 10.4 or above.
10.7 downgrade is almost the same as 10.3, the main difference is "sysupdater.3dsx", so just find a proper sysupdater with memchunkhax2.5 (I guess this is what it should be called?) and follow the normal downgrade guide.
Please correct me if I'm wrong at any point, I'm still in learning process.

I had made one for 10.4/.5/.6, and it will also work on 10.7. Here it is.Hey yo guys. Can someone link me to a guide to downgrade 10.7. Is it more dangerous than memchunkhax2? Thanks in advance guys.
