How to solve "PIT Partition Error" for S III I9300, Please Help !

Hello,
I was running on a stock non-rooted ROM, when the phone did not suddenly did not boot any more. Instead I am getting a "White Screen with some black lines" not even the Samsung Logo screen. I tried to acess the recovery mode, but this seems not possible. I can only access the download mode.
When I tried to flash a new stock firmware through odin, I got the error message: "There is no PIT Partition". Same happen when I tried to flash the firmware with three/four-parts.
I look through multiple threads and tried to apply the methods given in
1) http://forum.xda-developers.com/gala...em-gt-t2535367
2) http://www.android-hilfe.de/thema/i9...teilig.517665/
but non work so far, and I am always gettein either "Re-Partition operation failed", or sometime ODIN just stuck on "SetupConnection" and never go further.
Since this is a 2+ years old device, Service Center is not an option for me.
Can anyone suggest me a method to solve this error. Maybe provide me with new "PIT Partition" file, etc...
Thanks in advance.
