Thanks for helping.
I've downloaded SamsungPST but only the version 1.0.003 and I can not register dll file into this software. (I also do not know how to registry file)
My knowledge is limited but I am happy to try and learn.
I live in the city of Bandung in INDONESIA (Southeast Asia).
I've tried looking for mobile phone technician. But no one wants to fix it (probably because the cell phone of this type do not exist in Indonesia).
Thanks
