This is an ordinary GD87 misstake. Reflash the phone to a newer firmware with winmodo.

Thanx a lot mate, i tried it immediately after i wrote the post and it worked fine :)

Your'e welcome . Have a fun with your new working phone.

Flash phone with A29 (main+LP) and reset phone with CB2000. Works 100%, tested by me !

Thaxks people, I flashed the phone with A22 and it just worked :)
