Hi everybody, this is my first post and i need your help deeply.
I have been using Samsung SGH-i550w for about almost five years (and love it).
I have never hacked my phone.
It also has first firmware, that have come in it.
My problem is the following. I was trying to install some .jar & .sis file like x-plore, killer mobile, dictionary, etc...
Some programs worked well the others gave errors, then I have uninstalled the unnecesseary apps that I installed previously .
Then things got worse...
Firstly i cannot get response from pushing the yes button, the screen flashed and refused to open. I have tried many time but the result was same. :( I have restrated many time, with/without memory card. But still no response.
Today, while trying to send an sms, it happened again. When I tried to open messages screen flashed (open and close within microseconds) and could not open my messages.
When i restarted my phone, it said:
App. closed Data Connection Logger
(and it keeps saying every restart)
I can not understand what the problem is. My phone was working well till today. What can solve this problem?
Thanks in advance
