Please note you must be bootloader unlocked and S-OFF for this to work
you are doing this at your own risk dont blame me if something goes wrong i have tested this twice one on CM and once on Stock
that being said
This guide will help you return to stock un-rooted, locked, and s-on in the event you ever need to use the warranty
You will need the decrypted RUU from here

I recommend copy and paste for the command so you don’t mistype something
This will lock your bootloader and make it show LOCKED not RELOCKED
While still in the bootloader type
Once in ruu mode *blackscreen with HTC text* its time to flash the decrypted ruu make sure you have placed the rom in the folder and named it Rom.zip
Run following command
It appears some people are confused on the following. You must confirm your device successfully flashes the ruu before contiuning
It could work the first time or could error out multiple times typically it fails the first time then completes the 2nd bu not a promise also make sure you have checked the md5 hash
You will most likely get the following error
FAILED (remote: 90 hboot pre-update! please flush image again immediately)
Don’t worry this is normal (typically fails the first time) (also it could boot you out of ruu mode when it does) just make sure your phone still shows its in ruu mode
If it is not just retype
Then re-run the command
Once it finishes the phone will stay in ruu mode simply type
At this point you are stock unrooted and bootloader locked but still s-off to change this type
you should get a message back saying
“(bootloader) writesecureflag: partitions signature pass
OKAY [ 1.666s]
finished. total time: 1.666s”
now type
fastboot reboot-bootloader
and verify you are now S-ON andtype
and your phone will load to stock
note this will be stock version m7wlv_1.10.605.8 so you will need to take the ota to update to 605.10
hope this helps
