I haven't use quick sig patch. Only IOSUHAX in sysnand.So you use the sigpatch tool on the latest rpx/cfw download and then install to sysNAND? Do have the steps correct?
You install it with wupinstaller and launch it but only when sigs are patched. Its in installable format. You can't just turn on a wii u and boot it.
Its mainly useful for rednand/coldboothax sysnand.
