how to reinstall att v4.5 device software.

 

i want to use korean fonts but att did not have so i just download and installed

but my phone had connection problems ( usually, cell phone is not 'edge' and i could not use IM+..)

and i think the reason is i use wrong company program :smileysad: (just i think..)

So i want to reinstall att's v4.5 os .

 

i download and install to the computer and deleted vendor.xml file, but still device manager software does not read any update

(the first time i connect my device it shows there are some updates but after i go to update page, it said there is any update.)

 

How can i change my OS to att's os? ( i do not want to downgrade and reinstall 4.5OS if possible.. it takes so- lots of time!!)

is there any other solution to fix my connection problems?

Re: how to reinstall att v4.5 device software.

If you still have the other OS installed, you have to first do into Add/Remove programs and uninstall the "BlackBerry Handheld Software". Next you can download AT&T's 4.5 handheld software. If you're BlackBerry is from AT&T you don't have to delete the vendor.xml file after installing. Afterwards you can just go through the Application Loader to load the AT&T OS on your device.
