[matkoi]

I have a Nokia 7610 with

4.0421.4ch
Rh-51

firmware.Everytime I want to install any new game.This msg will come out.For the software I can install some of it only.

"App. closed ChildInstaller"

When I shutdown my hp and turn it on again this msg appear:

"App. closed CbsServer"

What is wrong with my hp?

Before you go to the Nokia Care ... try formatting it yourself

Hold the keys (Green * 3) while the phone is booting up. Don't let go until you see the word "Formatting ..."

Wonder if that'll fix it. When I had my HKG 7610 ... I didn't have any problems installing games. I have an Australian 7610 now

what is the key that i should press? (Green * 3)?
