Why my iPhone 4 cannot restore 1618. Stuck in DFU mode?

OK i have an iPhone 4 here. It doesn't boot up, see absolutely nothing on the screen, I have tried Tinyumbrella and it says its in DFU mode, iTunes is saying its in recovery mode and needs to be restored, I've used iReb and it says it is in a Pwned state but whenever i try to restore in iTunes with custom or stock it gets to either the apple or snowbreeze logo on screen and the spinning wheel and says preparing iphone for restore but then just stops with the 1618 error. I've tried reinstalling and basically anything else I can think of, just cant get passed that part of the restore.

Any ideas anyone?

Thank you so much for ur time taken to help me out here. this is just a new phone. the baseband is 04.10.01 since there is no unlock i was trying to restore a custom firmware to try and unlock it and i did not save blobs and when i did the phone went to dfu mode and always there. till this stage. is a brand new phone. i was using pc and it was giving error 3194 now i am using mac bcos i am able to run tss server on tiny umbrella. in windows tss server does not run is grewed out.
