First of all I must inform that I am very new to the android and used it 3 days back for the first time so please excuse me for any silly question.
I got the my new U8800 from China and it is preloaded with the applications of china telecom operator Unicom and all of the apps are chinese. None of the google apps were installed in it and even I was not been able to associate the device to my google account.
In desperation from somewhere I got the upgradation file "UPDATE.APP in the folder U8800 V100R001C00B136SP03CUSTC151D002(india)" and did the so called upgradation. Now I am able to get the google application and also could associate the device to my account but unfortunately I am having the following problems and concerns
1. Still all the chinese applications are there in the phone and are not deleted
2. When I am trying to open any of the contact in the contact list then it says "The process android.process.acore has stopped unexpectedly. Please try again". Hence I am not able to use the contact list in my phone.
I also want to know what is the difference between ROM and the firmware and what exactly the file "UPDATE.APP in the folder U8800 V100R001C00B136SP03CUSTC151D002(india)"
Also please tell me whether I can bring the phone in the original state in which I got it in my hands initially....
