I am using Blackberry 9780, and would like to inquire if ..its fine if i load any OS in it? I live in UAE, Dubai. so if i load a OS which is much more new and upgraded than my service providers or from my currently installed (default when bought separately form retail shops) is it fine or will it cause some problems wid my carrier.
Example: I am use Etisalat , iin Dubai. and i download Vodafone/T-mobile.. is it fine??
Like they said above, make sure it's for your device and delete vender.xml. Be sure that you're running a Windows PC also. This can't be done from a Mac.
