Thread: wrong rom

Hi, this is my first post here.I've just upgraded my xda2 to wm6.1 and all went well, but on a previous rom upgrade (to wm5 I think) I obviously used the wrong rom image. Although the upgrade worked, it left me with a qtek boot/splash screen. This is only visible when resetting, but a bit annoying nonetheless.
Is there any way I can remove/replace it?
Is it just a registry entry?
Thankyou
