Please help getting HTC bolt back to full stock for warranty repair

I need to send my htc bolt in for warranty repair. How do I return to full original stock state?
I can run the RUU.exe to return to stock os, but I still remain s-off, unlocked. Can anyone help me get back to s-on and locked?
Thanks.

I don't think it's possible to get it back to locked...
fastboot oem lock will get it "relocked"
fastboot oem writesecureflag 3 should get it back to s-on

Thanks for the response
Oem lock didn't work on the bolt, but I haven't tried the other command. I'm hoping I can at least get s-on. Maybe sunshine will give options to the bolt after s-on...
Didn't realize I didn't need s off for flashing roms.

I'm not having luck with the suggested commands:
D:\HTCBolt\fastboot-win>
D:\HTCBolt\fastboot-win>fastboot devices
HT6B404***** fastboot
D:\HTCBolt\fastboot-win>fastboot oem lock
...

D:\HTCBolt\fastboot-win>fastboot oem ?

Nevermind, guess I wasn't in download mode on the phone:

(bootloader) VERIFY_PASS (0)
(bootloader) Partition verify pass

Now to see how to lock.

NA

Here is how to get it back to Locked

leeco le s3 x626 locked bootloader problem

Hello guys,
i have a problem. I installed the new rom on my x626 and it worked great, after that i locked bootloader by my mistake and the phone died (bricked with red light)
i followed the instruction with the unbrick, but i am unable to install anything new because the bootloader is locked.
The phone also is in the bootloap state without any recovery. I got acces to fastboot mode only.
I followed a guide, it worked once on my another le s3 x626 but right now it dont want to work because bootloader is locked.
when i put "fastboot oem unlock" - it says that operation is not allowed. I am stuck at this point.
I know that i made mistake, i am idiot but I will be very pleased if someone experienced could help me.

You have to turn on Oem unlock within Developer settings. Use the " all in one to tool"to unlock to he bootloader or flash emmc.boot while the phone is in fast boot mode.
