Cannot restore, even the iPhone in recovery mode
My iPhone has firmware 1.1.1 when unboxed. Then i have try to unlock it. And i have successful, I can call, sms,wifi, ipod . Then I install summberboard from installer. But after restart iPhone , the Dock is alway in the top, and I can't launch the application is in the Dock.
Then I return summberboard, try to change the setting to fix it. But nothing change, then I go to installer again, and I have uninstalled a software name day0... (i don't remeber).
After that I can't use the iPhone (no touch, nothing). After reset I can only see the apple logo, and it stand there .
When connect the iPhone with iTunes. Itunes can see the iPhone. But when I hit restore itunes said "The iPhone couldn't be restored, unknown error occurred (-50)".
in My Computer (PC), I can see a drive with the name (Apple iPhone). And I can browse the photo that be taked by iPhone in that drive.
the iPhone still connected with wifi (because i can connect with my iPhone by using winSCP, can copy file, delete).
and When i put my iphone into recovery mode (sleep/wake and home button at the same time while connect the iPhone with iTunes). Itunes ask me the iPhone in recovery mode and it must be restored before use. But when I hit Restore in iTune, iTunes also say "The iPhone couldn't be restored, unknown error occurred (-50)".
Does anybody here help me ? Please. I have save all money to buy the iPhone and now I can't use it.
Please help me.
