I just have a quick question. I just bought a blackberry 8120 yesterday and when i first used it the firmware was 4.3 i stupidly upgraded to 4.5 and to do this i had to remove the vendor file. When i did this the Orange world icon dissapeared from my phone and i was unable to use the internet unless I use WI-FI so what i would like to do is put 4.3 back on. I understand how to downgrade (delete 4.5 software and then install the 4.3 one on computer right?) My question is will i be able to put that firmware one straight away and the blackberry wont reject it? as when I tried to install the 4.5 without deleting vendor file it would not update and i belive the vendor file is what tells the phone its Orange and puts the orange world logo on is that correct?
I have resent the service books a few times and nothing happens, the O/S wont downgrade at all even though i have deleted the vendor file (its not a branded handset ala it will work on any network) is there anyway i can downgrade without doing the Erase method? x
