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

[marcram]

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
...

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


D:\>fastboot oem writesecureflag 3
...
(bootloader) HTC KEY CARD VERSION: 7
(bootloader) VERIFY_PASS (0)
(bootloader) Partition verify pass
(bootloader) Write security level S-ON
OKAY [ 0.897s]
finished. total time: 0.900s

Now to see how to lock.
