[Q] Sony Tablet S Struck on Sony Logo - Sony Tablet S

Hi,
I have read all most all XDA forums, but could not help out the situation. I have a Sony Tablet S which recently struck on boot screen. I can just able goto recovery mode. I havnt enabled USB Debugging nor my tablet is root.
List all thinks i have tried but failed:
1. Hard Reset.
2. Reset to factory settings. ( from recovery mode option 3)
3. Copied firmware to external sd card. Tried to use (option 2) Update system to sd card.
4. abd push firmware to internal sdcard. (Permission denied.)
5. abd shell ( -exec '/system/bin/sh' failed: No such file or directory (2) -)
6. Unable to use adb while tablet is on normal mode(while struck on sony logo)
All above where failed. I am unable figure out what should be done.
I was able to pull few files.
