Removing old cfw issues

[LuckyLucy]

Hi I have been trying unsuccessfully to remove an old cfw (3.7 m33-2) from my 1000 model I just bought and I'm having no luck. So far I've tried pro update and Chronoswitch but I I get the same error on both "This program does not support your fw" Any guides that could point me in the right direction?

I don't recall if 3.71 has the keyslot issue but the way you remove a CFW is by just updating to an OFW, you are over thinking things by trying to install a CFW or use a downgrader.

Now if it is one of the old CFW's with the keyslot issue then here is a guide but I think you're fine so just update to 6.61 or whatever.

I have looked this up before I couldn't update the software it didn't let me. Chronoswitch and pro updater are firmware downgraders aren't they? They won't work.

It seems some people have had success using Hellcat recovery flasher so I'm going to give that a go after work.
