Galaxy S2 = Brick?



Hi all, my phone froze this morning so i took the battery out and put it back in again. However now it won't boot (stuck on samsung symbol). It won't start recovery mode and I can only put it into download mode. It was standard version from Android. I tried following this post of here ( however Odin responded saying it had failed. I then disconnected the phone, took the battery out and put back in to try again and now even the download mode doesn't work. Have i overwritten the bootloader well trying to reimage it? Is there anyway of saving it? or should i strip it and sell for parts?
