Hi All,
I'm new to this XDA and i'm really dying to get a clear picture of what is a Bootloader?
and what does an Unlocked Bootloader and Unlocking bootloader mean?
Secondly does Unlocking the bootloader and Rooting are the same??
Switch off your mobile,press power plus volume down button together for a while,the white screen u will see is called bootloader or HBOOT.
now if u will read very first line u will get S-ON and this state is called locked bootloader and when u will S-OFF it u will get an unlocked bootloader....the process of unlocking is called rooting or to gain whole control of ur phone by offing ur security...

an unlocked bootloader means that you have full nand access and you can manipulate the images on your phone - flash them. you can, for example, flash a new recovery image / another rom.

Hey everyone...I'm finally about to root my phone and I'm pretty excited. But before I do this, I want to learn/fully understand some of the terminology that gets discussed in guides, etc.
The term S-Off and S-On. S-Off pretty much gives you FULL access to everything in the phone, correct? I've seen people say that if you unlock the bootloader, the bootloader is unlocked, but you still have S-On. What I'm wondering is what can you achieve with just having an unlocked bootloader with S-On? People can seem to get root and install/remove applications, but when it comes to flashing ROMs, what happens there? I've read that flashing ROMs can still happen, but some of the optimizations/code/whatever in the ROMs won't be applied because it wouldn't have permission to do them. Am I right?
Just trying to finally figure out why people unlock the bootloader without doing the S-Off function.
if you unlock the bootloader using revolutionary then you'll have a fully unlocked phone(s-off/security-off). if you use the htc Dev site you'll get an unlocked bootloader but it'll stay s-on(security-on) because it keeps things like the partition where radio is and some other stuff locked. you can still install custom ROMs though because it does unlock your system,recovery,and bootloader partitions.

here I went and found the stuff I'd read....
Why is my security still on (S-On) after I have unlocked my bootloader?
Your device is shipped with Security on (S-ON) to protect your system software configuration (such as the bootloader, radio, boot, recovery, system and others). After you have unlocked the bootloader, however, you will have lifted the restrictions on boot, recovery and system. This means you can customize boot, recovery and system images on your phone as you desire. You can easily see that you have successfully unlocked the bootloader by looking at the top of the screen when entering the bootloader screen. Security is left on to protect things like the radio, and SIM lock.

Hello All..
I was an apple fan since 2007 The iOS, i wasnt really convinced with android till the day of release of HTC ONE X , This Phone Really Changes my mind with it Incredible Features and the quality of the device.
I,m new to android , i,ve learned how to unlock the bootlader , do the root and recovery , also installing a custom rooms and some MODs on it .
I need some information about:-
1- What does kernel and boot.img do?
2- What is the S-On and S-Off means ?
3- Is it possible to return my device as it is in the first original rom [bootloader locked, No root] as a new device? and HOW ?
4-Does MODs works on any room or for specific ones ?
5- What is H-boot ?
Any one use any instant messaging app like whatsapp Etc.. to contact him directly ? fast and easier
thank you in advance
1- What does kernel and boot.img do?
GOOGLE SOLVES EVERYTHING.
2- What is the S-On and S-Off means ?
HTC SENSE ON or HTC SENSE ON.
It enables or disables the htc sense interface.
3- Is it possible to return my device as it is in the first original rom [bootloader locked, No root] as a new device? and HOW ?
You can RELOCK your bootloader.... but anyways you lost your warranty (IF YOU UNLOCK YOUR BOOTLOADER).
ANd you can return to the original rom and config with this thread
4-Does MODs works on any room or for specific ones ?
See specifications about it.
5- What is H-boot ?
i DONT KNOW CLEARLY, BUT GOOGLE KNOWS TOO MUCH.
Well I can answer some of the questions:
1. boot.img contains the kernel inside (not sure what else)
2. S-ON or S-OFF I think means security-on/off
3 it is possible as long as the bootloader is locked/re-locked. You have to flash the RUU of your region/country where the phone came from. Without S-OFF we can't get super CID
I don't get your 4th question
5. HBOOT is loaded immediately when your phone is switched on, and it’s mainly responsible for checking and initializing the hardware and starting the phone’s software. It can also be used for flashing official software releases, as well as a few other things. HBoot can be compared to the BIOS on a computer.
1- What does kernel and boot.img do?
The kernel is like the middle-man between the hardware and the OS. it holds drivers for the hardware and tells the OS how to interact with the hardware.
2- What is the S-On and S-Off means ?
Security on/ Security off. It is another way to enable the phone to flash different Roms, The only way to flash roms at the moment is to unlock the bootloader but then HTC has a record of all unlocked phones.
3- Is it possible to return my device as it is in the first original rom [bootloader locked, No root] as a new device? and HOW ?
Yes it is, there are tutorials in this section on how to do this.
4-Does MODs works on any room or for specific ones ?
It depends what the mods are and how they are implemented, again it's best to read the threads on the specific mods.
5- What is H-boot ?
H-boot sort of holds the partition layout for the rom, from my experience with my desire different roms fitted different H-boot's. Not sure about anything else.
Added To my knowledge
Thanks All , i appreciate your fast responses
S-ON Locked = Security on + Bootloader locked = This is what your phone is out of the box.
S-ON Unlocked = Security on + Bootloader unlocked via htcdev = You can write new system and recovery images e.g. custom firmware. You can't alter the baseband or CID however. HTC run htcdev and know you unlocked it which will affect your warranty.
S-ON Relocked = Security on + Bootloader locked = You unlocked via htcdev and then relocked it. You can't go back to S-ON Locked normally. HTC know that you previously unlocked it.
S-OFF = Security off - You can alter anything you want in the phone including the baseband and CID value which determines what branding you get. You need a third party exploit to get S-OFF as HTC won't let you do it on retail handsets.
HBOOT is the bootloader. If you're concerned about getting S-OFF then you shouldn't update this at all since it may fix a vulnerability that is required later on for S-OFF.
Just for info:
Unlocking your bootloader does NOT void your warranty, your warranty is still valid for hardware issues but not software unless you have a branded phone, and if the software change made by you has affected the hardware somehow maybe by overclocking the CPU and frying it then the warranty will not cover it.
It should be noted that S-OFF DOES void all warranty.

is the command you type
Assuming you have the fastboot files in your PC and have the "boot.img" file together in the fastboot files.
1. Power Phone Off by Holding power button for 10 secs
2. select Fastboot with volume + or - then press power
3. plug your phone into your PC and open a Command Prompt.
(windows XP - Click Start > Run > type CMD in box then press OK
(Windows 7 - Click Start > type CMD in search box then press Enter)
4. cd to your fastboot files folder cd c:\fastboot
5. type in your command prompt "fastboot flash boot boot.img"

Hello guys, my sisters WFS is on build 2.26.707.2, could anyone guide me on how to s-off the WFS? the whole bootloader part i can't understand but recovery i do as i'm using a galaxys2.
The only way to S-off the GSM variant ATM is via XTC-Clip...............For know the only free way to root is by unlocking the bootloader.
To see if your current software is unlockable....Switch on your phone while holding the Vol down key.......this will result in opening the bootloader........if it says LOCKED on the top..........then your bootloader is unlockable
Proceed to step 1 on HTCdev,com

There is no way to S-OFF without an xtc clip regardless of what you're currently running. Fortunately you don't need to S-OFF in order to install custom roms, like csoulr666 said you'll need to visit htcdev.com and follow the instructions there. That will unlock your bootloader, but also invalidate your warranty.
For unlocking only
Try this link for unlocking without voiding warranty.
Hi just used ahhk2 to unlock my dhd but looking to put new rom on only problem is my dhd is s-off and bootloader unlocked and all roms give instructions for both methods which one do i follow s-off or bootloader unlocked.

Your s-off, this takes priority.
Just flash ROM direct after full wipe.

You are S OFF that's the idea behind AHHK2! To check that - power off your phone, then power it on with volume key down pressed, see the info on top of the screen it should say "... S-OFF..."
S-Off, Make Sure you did the Mandatory Wipes
Hi Everyone.
I'm having some difficulty returning security to on and also having the tampered banner removed. I'm hoping to send my phone back to warranty.
I've used this guide to get me through it but it left me with S-OFF http://forum.xda-developers.com/showthread.php?t=2751011
I've then tried this guide to get me back to stock with S-ON but it retriggered the tampered flag after I turned it off: http://theunlockr.com/2014/06/08/how-to-unroot-the-htc-one-m8-video/
Does anyone know if there is a way to enable security to on without triggering the tampered flag? Or if I'm doing something wrong with these steps.
Thanks for all your help in advance.
Find the appropriate RUU (If your carrier released it) and run it, it will remove the "tampered". FYI, next time dont worry about S-off so much. With S-off you could of put back on the stock recovery and relocked the bootloader and just sent it back w/ S-off, some 1% of devices mistakenly leave the factory w/ s-off.
HTC already has a record of you (based on your IMEI) unlocking the bootloader via HTCDev.com. You're going through a lot of effort to try to hide what HTC will already knows (that you modded the phone).

Htc know that just u take unlock code from them but they don't know if u use that code to unlock or not. U can just take that code and keeping for future so even if u have that code this doesn't mind u already unlock ur device. So if ur s off is always better to s on ur device for sending for repair
That just mine opinion ?
