Hi, i want to downgrade to iOS 11.2.1 my iPhone X with 11.2.5 developer beta 2, i'm on windows and i downloaded the v173 release....when i start futurerestore evertything is fine, the blobs are ok and SEP and BASEBAND too, but i get the error about the nonce...how can i set the nonce without jailbreak on my iPhone X?

You can't set the nonce without a jailbreak/exploit. However, you can downgrade in iTunes, since 11.2.1 is still signed. Option+Click (OS X) or Shift+Click (Windows) the Restore button and choose the 11.2.1 IPSW.

I try to do this but i get the error 3004...i fix this error and now the error is: impossible to found the requested resource. error 1015...

Try entering recovery using ReiBoot before restoring in iTunes. futurerestore isn't meant for restoring currently signed firmwares.
