Thank you for reply, but I cannot acces the phone. And I tried to connect it via your software but it won't recognize it.
The QWERTY phones have unique 3-finger hard reset combos. Try this: take out the battery for a few minutes and then reinsert it, then press the following three keys simultaneously
Shift +
Space +
Backspace and while holding those three keys, turn on the phone. Keep holding those three keys until the Nokia handshake animation rolls, then release them. It is a little tricky to get it, but it works on E6 and E72.
Last resort is flashing in
Dead Phone mode in Phoenix.
i hate to even ask, but did you try
12345 as the code? That is the default lock code.
