Really appreciate you help ,Geekmaster although I can't do either ways.
The first one, I read Jailbreak threads and found out that if I'm not wrong it's impossible to jail break my KT in my condition. The second one, I don't have serial to USB converter ,even have none spudger to open the back plate.Most of all ,it seems very complicate above my ken and need weeks to study.
So finally I may have to return it to US and ask someone send the replacement one back to me.
thanks you anyway.
