About unlock bootloader with htcdev - HTC Sensation

Hey man, before S-OFF, why we should do unlock bootloader via htcdev? (my hboot is 1.27.000)
What is the purpose to do that?
Can you explain this for me?
Thanks..

the first version of doing S-OFF requires htcdev unlock but the second one does not require
if you do not want to use htcdev unlock method for doing S-OFF method after see this thread
http://forum.xda-developers.com/showthread.php?t=1661631

he was refering more to the purpose of HTC Dev unlocking i guess
this is what i found but it is outdated (2009) dunno whether something has changed or not, so maby some nerds can explain further for him

OK, about sixteen million posts have been flying back and forth about what you can do with root, can't do, what S-OFF is, is not... So I'm going to try to clear it all up for you, OK?
ROOT means you have full control over the OS. From the OS, you can write to the recovery partition. Without root, the only way to write recovery is through hboot, which will only let you flash a custom recovery if you have S-OFF. But even with S-ON, you can write recovery from the OS if you have root. Then, with a custom recovery, you can write the hboot with an engineering bootloader, which has S-OFF. This way, you get S-OFF without a warranty-voiding watermark.
S-OFF means you can flash a custom recovery or ROM from hboot. Things you could already do with root, except that it's hard to get root while S-ON. But if you get it, you're set.
HTC says they'll ship an update which sets S-OFF, and then we're set, except their update will almost assuredly drop a watermark and void the warranty.
ANALOGY: Say the phone is a fortress, and you're trying to get in. S-ON means the gate is shut. If you root it with S-ON, you do it with an exploit, so you find a weak spot in the wall and pack it full of C4 and BOOM, you're in. S-OFF means they opened the gate from the inside, and you just walked in. Either way (S-OFF or root) you're in.
SUMMARY: With S-OFF, you get everything. With root, you get everything. End of story.
Final comment: rooting with S-ON means you used an exploit. Exploits are bad!! But HTC is forcing us to resort to such brutish, nasty means (blowing up walls to the fortress) because they locked the gate before selling us the place. We have a right to get inside, but they aren't opening the gate, so we have to get in some other way. Remember, if you can blow up the wall and walk in, a malicious program can do so too. Exploits are bad, and HTC should patch them. But let's get some legitimate use out of them first, ehhh?

[Q] confused with the terms.. need help with root

hi..
i am all stranger to HTC world.. i have been using galaxy s, s2 and ace.. things were easier when it came to rooting and flashing custom roms.. or at least there was less terms.. 3 days ago i bougth Sensation XE and since then i have been reading every page but the more i read, the more i get cunfused...
so, what i want is basically trying new kernels, OCing, using apps like setcpu or titanium backup etc.. in order to do these rooting the device was enough with the galaxy devices.. but here there are lots of terms..
here is what i think i understand;
S-off= this means unlocking the NAND part to be re-writable i guess.. the funny part is; i want to root the device and i guess i have to S-off the device but it says in order to S-off the device you must have alredy rooted it? or i am wrong?
Hboot version=i think this is very important since we have to choose the methots according to this... mine is 1.27.0000
super CID= no idea what this is.. but i assume it has no important role on rooting..
and there is the bootloader unlock option= htcdev.com is doing it but they say if i do it my phone is out of warranty.. it is just a 3 day phone and i dont want to lose the warranty... and i also have read some post about it not being a complete unlock.. so any method other then offical HTC ones would be better for not losing the warranty (i am sure even if i lock it back when its necessary, HTC will still have the records of me unlocking my device and wont let me use the warranty) ..
and there is this guide on the development section, it is really helpfull but the date of it tells me it was before ice cream sandwich update and 1.27.0000 hboot version and some of the instructions confirms that... so i guess i need some other method to root my device ... (after everything i am not even sure if the rooting is excatly what i need)
long story for short; i am lost among the terms and instructions.. especially after i tried to S-off my device in order to root and learnt it needed to be rooted first in order to be S-off .....
so please help me with the terms and instructions..
thanks ..
Okay, root is not needed to s off.
S-off disables the security on your bootloader.
Supercid means you can flash any piece of software no matter what area or network it was intended for, as each one has a cid code that restricts the software to the network or countrys phone e.g. unbranded sensations cid is HTC__001 and Vodafone would be VODA__xx. Supercid changes your cid to 11111111 which means everything that is protected by any cid code will work on your phone.
Back to s-off, using revolutionary tool is pretty easy as long as you follow the instructions correctly but will not work on hboot 1.27 so it requires downgrading using an ruu or eng. Hboot 1.17 or finding another method to s off 1.27, once s off using revolutionary all you have to do is flash a custom recovery and then flash superuser and voila your rooted. But you can also s-off, install custom recovery, upgrade firmware to 1.27 and flash a prerooted custom Rom which obviously does the trick. Just make sure to keep a track of what firmware you are on and make sure it works with what your doing and the Rom you're using. Oh and htcdev unlock is not necessary as you can flash a firmware with a unlocked bootloader plus revolutionary also unlocks bootloader. And as far as warranty goes, once s off or bootloader is unlocked your warranty is VOID.
Hope this helps

Fİnally! everything makes sense thanks a lot..
so the first step is to downgrade to a firmware which i can S-off and unlock, then to get back to pre-rooted version of my current firmware..
so i assume just like i can downgrade, S-off and unlock, i also can upgrade, S-on and lock back when i need the warranty?
Almost firmware contains the radio and Hboot etc, to obtain root you just first s off on the downgraded firmware, then upgrade to an unlocked firmware that is for ics. The firmware for ics is 3.32 which contains Hboot 1.27 but of course you cannot s off on this version of Hboot. Then flash a pre rooted ROM once you have gone back to ics firmware using a custom recovery. Once s off, you will not lose it when upgrading to a new firmware. But to s-on is risky but if you manage to do it without semi bricking your phone and then flash a locked bootloader HTC will never know you've voided your warranty as long as your on an unrooted Rom. I will pm you a great link for doing this and explaining as I know this is confusing. I won't post it here because its on another forum.

downgrade

Is there any way to downgrade boot loaders? I am on hboot 1.45.0013 s-on and was wondering if there is anyway to downgrade. Is it even possible to use someone elses old backup from the 1.44 Hboot, to help downgrade? thanks
you can now get S-OFF on that hboot using Juopunutbear: http://forum.xda-developers.com/showthread.php?t=1576672. look it over first tho, it has taken some people many tries, and there have been some bricks from not doing it precisely right. here is another thread on it to check out: http://forum.xda-developers.com/showthread.php?t=1617488.
this is the only way right now to switch hboots or downgrade from 1.45.0013.
fricken awesome dude. thanks
hmmm looks real risky. do i have to have root first? does the bootloader have to be unlocked with the HTC dev before this can happen?
no problem man. and nah, I don't think you would need to be unlocked, but you could ask in their thread to be sure.

From the JuoPunutbear site :
In order to use JuopunutBear you must meet the following pre-requisites:
Be unlocked using the HTCdev bootloader unlock
Be on the stock ROM and be rooted (have superuser and/or an unsecured boot image installed)
Some custom ROMs may work, however we cannot verify them all. If you are not using a stock ROM and have problems then this is most likely the reason.
Have a spare microSD card or to have backed up all contents of your SDcard, the card may be wiped, while we try to restore the card to it’s original state is is possible that this will not succeed
Have fastboot and adb drivers installed and working (windows)
Have usb debugging enabled
Remove and potentially interfering phone software which such as HTC sync, Andro sync, PDAnet etc, iTunes has also been noted to cause issues.
Have a legth of insulated wire of sufficient length to join the contact points for your device. See images and videos for device specific information.

"tampered" and s-off

OK, so I am learning android (using HD2 now) and from what I understand when you use the htc boot loader unlocker you end up with a "tampered" warning somewhere that will let htc or your carrier know that you have unlocked your bootloader.
Does having s-off help you to be able to trick the phone from knowing that you have been into it if you flash it back to stock?
I am just worried about keeping insurance on the phone if once I unlock or s-off they will no longer cover it.

I think that particular device will say, tampered. Soff is like security off you can fash roms and do many things with soff but no it does not trick the device into thinking its not tampered. With my device I can s on return to stock but I'm not sure about yours.
It might have tampered marked on it.

It doesn't set a "tampered" flag. The stock bootloader has a caption at the top of *locked*. When you use htcdev to unlock the bootloader it will change that caption to *unlocked* and it cannot be undone.
S-off, on the other hand, does not notify HTC or your carrier of what you have done. It is also reversible if you really need to set things back to full stock.

When you use HTC Dev to unlock your bootloader it does show Unlocked on the Hboot screen. But if you re lock the bootloader it displays re locked on the Hboot screen and not locked as it is originally. S-off can be reversed with out any trace of it being S-off. And now that the unbricking project has come up with a way to recover your de ice if going S-on soft bricks your device it is way less dangerous now.
At realsis, think about S-off as being like HSPL for the HD2.
I believe someone has figured out what was being set differently, and you can in fact return to "locked"

Go on........
Don't know if this works for the Sensation, but if someone is trying to go back to locked hboot, give it a try.
Go back to totally stock. Flash a RUU, preferably GB so that you have an earlier hboot that can be easily S-OFFed again.
fastboot oem write secureflag 3
Reboot and you should be S-ON again. AGAIN, MAKE SURE YOU ARE TOTALLY STOCK WITH A SHIP HBOOT OR YOU WILL BRICK.
Use revolutionary to S-OFF again. Hopefully, you will be locked at this point.
If not, repeat, but use JuopunutBear to S-OFF.
If you're still unlocked, this method doesn't work on the Sensation.

Desire S Bootloader Question

I have read various guides, and eventually taken the plunge to downgrade my bootloader.
htcDev Unlock
Goldcard
Install oldest RUU
S-OFF using revolutionary
Flash CWM recovery
Backup Stock 2.33 ROM with Sense
Install CM9
Feeling quite pleased with myself, even though you guys have really done all the hard work, I've just followed the steps!
What I can't find is this;
If I go back to the Stock ROM and updates are offered OTA, if I accept, will this, not only bring me back to 2.3.5 with Sense 3.0, but also change my bootloader back to 2.00.0002 Locked and S-ON ?
Unfortunately it will be *RELOCKED* and S-ON

What he said. If you wanted to remain "locked" and not "relocked" - you should have avoided unlocking the bootloader, and should have used temp-root for misc_version.
Ok, what are the inplications of being 'RE-LOCKED'
Like CM9, but get the feeling development stalled, also certain apps won't work Nat West being one, though I suspect that is to do with their development.
Thinking about going back to Stock. If I do this via OTA, my bootloader will be upgraded back to 2.00.0002, 'RE-LOCKED' and S-ON, then wait for official OTA upgrade to ICS, which seems not to be happening as per HTC announcements. Even then I may have issues with apps that haven't been coded to deal with it.
If I am 'RE-LOCKED' can I not use htcDev again, or am I stuck with the Official bootloader etc and unable to load other ROMS, or can I just repeat the processes I have been through already?
I have also been reading about unlocking with an XTC Clip, where would I get this done, Is this a better solution? etc etc..
No issues with RELOCKED except that your warranty is gone.
If you have no warranty you can go for XTC Clip, since permanent S-OFF will give you more freedom in terms of modifications. Personally I consider flashing boot.img separately each time as annoying.
As per the unlock again, it should be possible, but I am not sure if this can be done by a fastboot command or the unlock token has to be flashed again.

When I unlocked mine I remember reading somewhere that the token would need to be used again if the phone was re locked. So I kept it just in case

Difference between SuperCID and Unlock for HTC One S

Hello,
I am quite confused about the term SuperCID and what it means. My sister got a HTC One S. I unlocked and unrooted it for her quite a long time ago. Now, I want to get S-off but I can't do it because I don't have SuperCID. I read on the forum and some people say that Super CID means your phone is unlocked, while other say you have to use the command "fastboot oem readcid" to check if you get SuperCID.
I use "fastboot oem readcid" on the HTC One S and it shows TMOB010. Then does that mean that I don't have SuperCID? Then what exactly is SuperCID when the HTC One S is already shown "Unlocked and Tampered" on the fastboot screen. Pleas let me know. I am quite confused with all this terminology. I can look up direction to get SuperCID but I want to be sure that the phone has it or not before I proceed.
Thank you for your help

SuperCID will be a seven digit string of the same number (1111111, 2222222 etc). These CIDs gain special access to partitions normally locked down (how they test stuff). Having this CID means you can do more stuff, meaning write different sectors etc.
So TMOB010 means you don't have it.
To make a complete answer; unlocked is just when you unlock your phone via HTC's website which allows you special access to partitions and fastboot, however not all partitions are accessible - whereas with SuperCID you can access them all.

correction.
supercid does not allow special acces of different partitions, who told you that.
its just a masterkey for stock softwareversion implementation, nothing more.
its either a eng-hboot or a s-off implementation that gives you that freedom.

That's incorrect. You can have a stock HBOOT and be S-ON with SuperCID. SuperCID isn't the implementation, it's a way to gain the implementation. And it allows you special access in that it's a masterkey...
Example; I gain S-OFF with Moonshine. Does that mean I have SuperCID? No. Does that mean I have an ENG HBOOT? Yes. Can I reflash that HBOOT to stock and keep S-OFF? Yes.
SuperCID allows the flashing of any ROM regardless of the carrier it was meant for (special access) and it also allows for the writing of Ext_ROM (special access, again - see CID LOCK).

No supercid is just a generic cid.
It has no hardware advantage over a stock cid. It's mainly used for unbranding.
I always have my devices on stock hboot and stock cid. Only s-off is what I want.
Haven't found anything I couldn't flash.
Like your link says VENDERLOCK thus software.
It's the unlock (xda-dev) part that provides the access of certain partitions.
With s-off even more is available.
S-off and hboot have no direct relation.
Example: Lower stock hboots can flash radio with only a unlocked device. Higher can't.
What's the difference a device unlocked supercid and a device unlocked unbranded cid. ?
Is there any rom custom that can't be flashed with just unlocking,
Lets make it supercid can I flash more roms?
Its just an coincidence that with the newer devices supercid was needed for getting s-off. It didn't used to be that way.
Hell easy unlocking didn't even exist.
It was s-off or bust mostly.
The link you give is not that clear.
ext_rom have you read there description?
I don't think that's a really secured partition. Do you?
Typing on a phone is fukd if it gets to big.

Yeah exactly it removes the vendor lock which gives you access to write partitions you otherwise wouldn't be allowed to in that way.
I think we're actually arguing the same point here dude Think I misread your point about HBOOT in the second post.

Hmm...., so, based on the info, it means SuperCID is not that different from generic CID. However, you need it to get S-Off, which in turn allows you to write to different partition. Because my ultimate goal is to get S-off to update my sister phone to the CyanogenMod 10.2. Is that correct or did I miss anything?

Blunt answer: you need superCID for S-OFF, unlock isn't enough by itself.
