I have this version of software for AT&T, and I would like to know: If I remove tampered flag and reset to locked and S-ON and then restore using a SIGNED RUU EXE FILE for this software version, will I be ok (as in not get a security warning and look 100% stock)?

If you have the RUU just run it, you don't have to relock or anything unless you want to - just don't go back to S-ON as it's not required
OnePlus One (Sandstone Black) 64GB
ROM: CyanogenMod 11S (XNPH25R)

HTC One M8 (Gunmetal Grey) 16GB
ROM: 2.22.401.4 (KTU84L) | HBOOT: 3.18.0.0000 S-OFF | Recovery: Stock | Baseband: 1.19.2133147.09G_20.57.4196.01L_F | Kernel: Stock | CID: HTC__001

If you have a question, great - but DO NOT PM ME WITH IT!!! | [GUIDE] Return your EU M8 to 100% Stock (S-OFF Required) | [GUIDE] Return your OPO to 100% Stock

Will they service the phone if it is S-OFF?

Never been an issue in the UK but can't comment on other countries. If you wish to S-ON the unit only do so after running the RUU as you'll then know for certain you have a 100% stock system

I updated to this RUU before flashing TWRP, so if I lock the bootloader and then run the RUU, can I run fastboot writesecureflag 3 with a locked bootloader once I restore the RUU?

Thanks for the guide, returned my phone completely to stock (selling the phone and going back to a nexus) including s-on, all went just fine.

Thanks for testing it out for me. It's good to know if I ever want to revert.
