Then this may be the cause for the brick. You need to understand which patch does what. This hight light my point "...choosing patches is not ideal for newbie especially when you're to downgrading and flashing to SYSNAND..." in my previous post.
I just realised it, hence the post ^^
At the time i read that part it told me to only check enable emunand and driver signature
Right now Step 18 of Part 3 says [Activate the "Enable EmuNAND", "Disable Signature Checks", and "Survive reboots when launching some titles" patches, then press Start to continue]. That's that 3rd option I didn't find so I checked the remaining one (something about forcing not writing the FIRM partition or something).
