Doubt about S-OFF

May I know if One X is able to be S-OFF, is it mean that even the bootloader status is locked and we still can root and flash custom rom? How it different with unlock bootloader using HTCDev? sry for noob question..
No you need to be unlocked to root and flash custom roms. As of now HTCDev is the only method to allow unlocking.
Simple method. We don't know when Revolutionary will release their tool.
S-ON + LOCKED = You can only use official HTC firmware and only for the specific branded version you have.
S-ON + UNLOCKED = You unlocked it via htcdev. You're able to change the system and recovery images to allow for custom firmware. You can't alter anything regarding the baseband aka cell radio. HTC know you unlock via htcdev as they make you enter your serial number and other details to generate a phone specific unlock token. This will affect your warranty as any software caused faults are your own problem. General hardware warranty is still the same.
S-ON + RELOCKED = You relocked it after unlocking via htcdev. Same as S-ON + LOCKED except it shows you relocked.
S-OFF = No restrictions at all by the bootloader. You can alter everything. HTC don't let you do this and you need somebody else to work out a flaw in the bootloader to do it. Technically this voids your warranty as well but if you relock and don't leave any evidence that you did so then HTC won't know.

No one knows about S-off.
It doesn't mean we can root and flash custom roms even on the locked bootloader. It was a different and unofficial way of unlocking the bootloader which can be locked again when we need.
We can do the same thing even in this HTC dev method, I mean locking the bootloader, but after that the status of the bootloader will be RELOCKED not locked. That means HTC people may know that our device is already unlocked before.
One more thing (which I heard and I am not sure), we can't flash ported roms on our device unless and until we have S-off.

[Q] Warrenty and Unlocked Bootloader

My M8 is having some touch screen problems, and I want to send it in on the warranty to receive a new unit. Will they replace it even though the bootloader has been unlocked? Even if I re-lock it and use s-off to make the device seem locked, wont they still have record from the htcdev site that I unlocked the bootloader? If they do, will they not replace the phone because of the unlocked bootloader, even if the issue has nothing to do with the bootloader being unlocked?

Bad model id and relocked bootloader.

Hello all. I'm using a verizon m8 on tmobile (the model i have is CDMA and GSM) I tried to change the modelid to flash new firmware, but I must have done something wrong and now my model ID says "modelid: tpms:tpms:-:ukonoto".
Also, my bootloader now says "relocked" and I cannot access recovery, only fastboot. I have s-off and am rooted
So, I am curious what commands or steps I need to take to fix my model ID, and how can I get my bootloader back to locked as opposed to it saying "relocked" And lastly, what can I do about not having access to my recovery?
Any help would be greatly appreciated. Thanks!!

How to unroot, lock bootloader and s-off for warranty return

Hi
I need to send my phone back for a warranty repair but I am confused about the exact steps to take.
My phone is currently S-OFF, rooted, has a TWRP recovery installed and has the latest Vodafone (VODAP001) stock rom installed.
What steps and in what order should I act in order to be left with a phone with a LOCKED boot loader (not RELOCKED/TAMPERED), unrooted and S-ON?
The instructions in a particular online link talk of locking the bootloader and then flashing an RUU but I can't find one for my Vodafone variant. (CID: VODAP001)
I have been going round in circles for the last few hours.
At one point I did lock the bootloader and then did the s-on but ended up in a boot loop to the bootloader - (probably because I forgot to unroot?)! Rescued it using the HTC Bootloader unlock code, reset and then rerunning Sunshine for S-OFF.
I can't seem to work out what to do without an RUU file.
Any help will be greatly appreciated.
