Best thing to do and is recommended is to uninstall things like spoofs,fuckpsn then go back to 3.55ofw and then update to the 4.21cfw as ive said ngu or myself are not responsible for your ps3 getting bricked

goodthing i kept my 2001A ps3 ^^

so is there a cfw for dex users? i really havent done alot of checking since nothing is really perfect.. i have a 3 dex units now ...

When it says this, does it mean it might brick or it won't brick or what?

wont brick but recommend you go back to 3.55ofw then install rogero in recovery menu

Alright
