Hi,

I have a 7100v and have just upgraded to OS4.1. I took out the vendor.xml file and as such the phone is working.

However, the screen has gone mad. It's black and white apart from brick breaker icon that's still in colour.

What do I have to do to get it all working again?

Please help, company phone

Sounds like the original default theme has gone missing? See if you have any other options under themes? Best bet back up, use the javaloader.exe to wipe the device clean and preform a fresh install.
