no this is not to downgrade, you can use flasher (E3, Progskeet, etc) to do so. basically this tool is used to sign the pkg on firmware update. since rvk_verifier.self not touched before by old CFW.

so now all CFW can run smoothly, without toggle activated and hdd replace issue is fix

btw you need spkg-key and iv from retail one to get this application working.
