Potentially yes. Depends what they have baked into it,could just be Vodafone network, messed up CSC and security etc etc. But then again, probably not.
Word of advice though, seems like Carrier firmwares aren't flashing for people and they seem to work OTA only. The normal XEO Polish ROM works fine for everyone bar HK users.
