What to do when Ruu doesn't work for you?

Noob here.

I manage to delete the os on my phone. I've search throu the forums and have tried to many things with no luck. I can still get into Hboot so I know theres still hope. My Hboot Reads:

Tampered
Relocked
M7_WLS PVT SHIP S-ON RH
HBOOT-1.56.0000
RADIO-1.00.20.1108
OPENDSP-v32.120.274.0909
OS-
eMMC-boot 2048MB

I was S-OFF when I first tried to use an RUU (I had ViperOne 6.2.1 installed) and it didnt work. Why is it S-On now? I have no Idea.

I just tried the new 5.03.651.3 RUU (after relocking bootloader) and it wont get pass "checking header".

I have no idea what to do now. Please let me if you need more info about my phone
