I tried to reset it by pressing Power + VolDwn + Back + Reset and other combinations, but nothing happened. I can’t connect it to mtty as well (No USB option).

Any ideas???

Thank you in advance

The reason why the unlocker does not work for you is that your carrier (Cosmote) uses GSM technology and this unlocker is designed for CDMA. This is clearly stated in the instructions (in large bold font at the top of the page).

Unfortunately, I am not aware of any methods to recover a GSM phone from this state. However, if you find a solution I suggest you head over to xda-developers. They have a lot more resources for GSM phones.
