I cannot s-off my Sensation XE with revolutionary tool.
It says to fill in a form at their site with device type , hboot version and serial number.
I have hboot version 1.27.0000 and the available versions on the form are only 1.17 and 1.18.
Except this when i run the tool it says that "your device , pyramid with hboot 1.27.0000 is not supported at this time".
i have installed the htc driver.
i powered on my phone without hboot (i removed the battery and then turned on).
i have ICS 4.03 version 3.32.468.112 (i got it OTA two days ago).
How can i s-off and then root my phone?
Please help me because i have not done anything like that before.
You have the wrong hboot version. Using revolutionary won't wont work for a phone with the ICS OTS use http://forum.xda-developers.com/showthread.php?t=1611981
That.
you say that i must change my hboot version for it to work?
how is it wrong?
it is the one that my phone had stock.
and how can i change my hboot version?
will be all ok then or my phone will become unstabel or lose something?
Try the tacoroot method. I had a set of detailed instructions somewhere.

If you want S-off you will have to use the Juopunutbear S-off method linked above. Her is z link to the only detailed guide for the Sensation there is now.
Now by all means please understand you will have to use HTC Dev to unlock your bootloader before you can use this S-off method. When you use HTC Dev to unlock your bootloader it can cause you to void your warranty.

Sorry about that, don't know why it did that. I fixed the link in that post now.
does anyone know if there will be a new tool that supports the latest hboot versions?
if there will be i can wait to do it that way because the others seem a little risky to me.
It's Juopauntbear or nothing at the moment, and it works fine.
You can always just use HTCDev unlock for the time being, that let's you flash recovery to swap ROMs & gain root.

i read at their site but i didnt understand much.
what is the juopauntbear method and what is the HTCDev?
the only thing i saw is that you do something with a wire at the phone and i am confused.
is it the same thing or i must do both to s-off?
i entered rhe HTCDev unlock page and it has some instructions.
if i do this will i be able to s-off or i must then do the juopauntbear tricks?
You must do the juopunutbear method if you want to s-off
But befor that you must use the HTCDev and root
You must understand that yll lose your warranty if you use the HTCDev method.
so the only way now to s-off with hboot 1.27 is juopunutbear right?
What exactly do the HTCDev then? I see that unlocks the bootloader.
I think is in different order than with revolutionary tool (first s-off then root then anything else but with this method you need first Htcdev then root then s-off) or am i wrong?
HTCDev does not unlock the bootloader only parts of it, so thats why you have to first unlock via HTCDev and then root and finaly s-off with Juopunutbear...Thats the only way to fully unlock your bootloader

Understood.
That is the only way until revolutionary release a new tool that supports the new hboot versions i think.
I think i can wait a little more for s-off.
Thank you all for your help and your time.

Starting adb server
get online devices (much more rapidly passes to the next step)
Chose the Connected Device: (recognized HTC Desire S 2.3.5)
get devices online
waiting for debug mode

Unfortunately Desire S is alwais *** LOCKED *** S-ON
I repeated the procedure many times, but the result always the same.

You are confusing rooting a phone with gaining S-OFF. To date there has not been a solution developed that will S-OFF HBOOT 2.00.0002. You can change the "LOCKED" status to "UNLOCKED" by using the procedure at HTCDEV.com and this will allow you to flash a custom recovery and then install custom ROMs.
only way to get Permanent Root is to make your device S-OFF....what do you use to root your device?"unlockroot"?

i repeat the only way to get PERM ROOT IS to get it to S-OFF or to UNLOCK BOOTLOADER VIA HTC DEV.. If Unlock Root works for you then its just SHELL ROOT!.. the root disappears when you restart the device.
And the ONLY way to get S OFF is to DOWNGRADE and use Revolutionary. (which you can do anything you want)
you can unlock bootloader also with HTC dev.(which only let you root, flash roms and kernels)
YOU CANT DO ANYTHING(root,etc) WITH A LOCK BOOTLOADER, same with a S-ON.. Read the forums...http://forum.xda-developers.com/showthread.php?t=1146601
Ummm... Correct me if I'm wrong, but @up talks b.s. ... My d.S is s-on, bootloader unlocked by htcdev and perm rooted.
I've restarted my device numerous times and not loosing root... Latest hboot on it ofcourse.
Oh... And rooted with "super one click". (if it helps with anything)

Dude,, youve unlock using htc dev. that means you can get PERM ROOT.. Unlocking with HTC DEV mean you can flash roms/ root but not as equal as S-OFF. As you can see. it still S-ON because there are still security parameters in the device which are still ON in order to protect the system. S-OFF can only be done using Revolutionary and by that you can do anything with the system.. "UNLOCK BOOTLOADER= FALSE S-OFF"
I tried to s-off my phone using revolutionary but my hboot is 2.00.0002 and revolutionary doesnt support it, is there any other way I can s-off the phone now???

READ.........try looking in the INDEX
There is a section that will assist, entitled "UNLOCK your Bootloader by HTCDev (S-ON - Security On) (HBOOT>2.0)" you have two options 1) downgrade you hboot & unlock using revolutionary, which isn't an easy thing to do, but is better and easier in the long run.
Or 2) use htc dev to unlock
all the options and guides are there for you to read.....I suggest that you spend at least one evening reading and comprehending before you progress further.
Go for the first method, downgrade you Hboot and then unlock bootloader and get S-OFF using revolutionary, it is by far the best way in the long run. Just remember, if you've unlocked the bootloader using the HTC-dev you need to lock it again.
I've just got a new sensation with s-on and h-boot 1.27.000 and official vodafone ics firmware.
I wanted to frlash arhd 6.6.2, but as long as I got there I have to s.off the phone...
But I cannot s-off the phone if it's h-boot 1.27.0000, so what do I have to do?

Hi,
You are right.

Youre gonna have to unlock your bootloader by using htc's official method (google it). Then youll be able to install CWM and whatever else. There are limitations, theres a good guide in the development section about htc official bootloader unlocker. Read that before attempting.

Yes you will have to use the HTC Dev method right now if you want to flash a custom ICS ROM being as those are the only ones you will be able to flash with the Hboot you have. But know this ahead of time the HYC De. Unlock is very different then the Revolutionary unlock. Click the link in my sig to learn mote about the HTc Dev unlock and what it allows you to do. But if I was you I would just wait until Revolutionary supports Hboot 1.27.0000, or someone comes up with a Hboot downgrade for the Sensation cause the HTC Dev method does not fully unlock all portitions except the radio portition like Revolutionary does. Plus it leaves evidence your bootloader has been unlocked so HTC can say your warranty is void. Check out this post to as it gives a little more insight on HTC Dev unlock.
So to root the device I have to CWM it, to CWM it I need to unlock the bootloader?
But, If not rooted, unlocked nor CWModded, can I just install ARHD?
Ok, let's take it the other way round:
My phone is locked, hboot 1.27.0000, S-on, cid VODAP102 and not rooted, but last official stock ics.
Now I want to install last ARHD, what should I do and how??

To flash AHRD you will have to have a unlocked bootloader, either by HTC Dev method or by Revolutionary method. Now as stated by you, malybru, and myself we all know Revolutionary is not compatible with Hboot 1.27.0000 (as of right now), which your device currently has. So this leaves only the HTC Dev method. Now I personally agree with others here on XDA, I would normally stay far away from unlocking via HTC Dev. But seeing as you bought your Sensation new with Hboot 1.27.0000, you really have no other alternative but to wait for Revolutionary to update or for some other means of unlocking becomes available. Also if you do manage to downgrade your Hboot you will have to use HTC Dev to do it.
Now I am in no way saying you should use HTC Dev, nor am I advocating HTC Dev. I am just trying to inform you. What you do with your device is your choice and your choice only. But what ever you do, please post back here with your decision and if applicable any results.
Also if you was wondering why you have to use HT Dev to downgrade Hboot, read this post. Yeah I know it is for GB ROMs but I imagine the same probably holds true for ICS. I mean it is the HTC Dev unlock that allowsyou to downgrade in that senario. But what do I know.

Sure, exploit H.Boot 1.27.0000 for S-Off is revolution, new model of HTC phone is same like HTC_One
****ing S-ON policy HTC because you total locked us
And that is why HTC always following behind Samsung nowadays
I'm waiting XDA revolution
Hi,
I'm new to this forum and new nothing about rooting until a few days ago...quickly discovered the fact that Revolution does not support 1.27.
I unlocked with HTC DEV, ran recovery-clockwork-touch-5.8.0.9-pyramid.img using Fastboot CLI.
After that I backed up my stock Vodafone ICS ROM using CWM then switched to the XDA guide for rooting with su-2.3.6.3 and followed rest of XDA guides for installing a ROM (really useful guides - Thanks!!)
Within an hour I had gone from stock Vodafone ICS to Virtuous Inquisition-v4.0.1
I'll admit I got hooked up on flashing recovery and was given some guidance by a friendly soul but figured the rest out from this forum..
Below is the details of my phone, I am not able to S-Off the phone, require help. I tried couple of things however gives me error.

I refered to a you tube video " How to S-off htc desire s" the first video that shows up. My phone is already rooted using the hdc dev kit, however when I am trying to do s-off the software gives just a message "Error". It also fails at signature.
do let me know what more information can I provide.
If you have a guide that I can try and share the results with you do send me that as well. I am new to rooting the phone, so sorry for not providing any info that is required.
You either htcdev unlock or you s-off
You'll now need to relock your phone to undo the htcdev and then downgrade you phone in order to properly s-off using revolutionary.
There are various downgrade guides in the index, see link on my signature

No, it's S-ON, but writable on /system partition due to HTCDev unlock. It only means that you don't know the difference between S-OFF, rooting and HTCDev unlock - and misleading others.

SAGA PUT SHIP S-OFF RL
S-OFF ... Security off
Rooting ... Grant root for the device, like su on linux
HTCDev unlock ... unlocks the bootloader
But its ok I just tried to help...
Then you can try to avoid confusion providing more detailed info, like:
"I have used XTC Clip to gain S-OFF, then used htcdev.com, without any particular reason, then got rooted by SuperOneClick"
Your previous post can mislead some non advanced users that SOC can provide S-OFF, without using additional tools.

Ok..
I unlocked my HTC Desire S following the instructions on HTCDev.com. Afterwards I rooted the Phone,installed Busybox and installed ClockworkMod Recovery using the SuperOneClick tool for Windows 7.
And now I am able to flash Rom and Radios.
Nope to upgrade your Radio you have to be S-OFF
Maybe it was shipped with S-OFF because I had a brandig first.
I doubt that it was shipped S-OFF and even if, why would you unlock it with HTCdev ?

And you can flash radios only because you had a phone which already was S-OFF, either during manufacturing or by XTC-Clip, and you just didn't understand it and uselessly unlocked it while you could have done whatever you wanted with it. And S-OFF is the only reason you can flash radios, and HTCDev unlock didn't actually add anything and didn't allow you anything - just as it won't allow any non-S-OFF user to flash radios, and won't turn S-ON to S-OFF. But what do I know, I was just passing here.

It is unlikely, but certainly possible. In the early days of Desire S development (back when we had to use the XTC-Clip hardware to obtain S-Off) there were some people who got their devices brand new already S-Off.
ok, back to the topic:
the simpliest way to gain s-off without xtc-clip is to downgrade the bootloader to HBOOT 0.98, and gain S-OFF with Revolutionary. After you did this you can run the latest ruu, which doesn't influence wether your s-off or s-on. Finally, you've got a device with hboot 2.02 and s-off.
After using revolutionary you are already S-OFF!
If you want to upgrade your HBOOT don't run a RUU AFAIK it could brick your device ... use this tutorial

http://forum.xda-developers.com/showthread.php?t=1679338
You can flash ROMS which require HBOOT 2.x WITHOUT writing commands in ADB.
With HTCDev you can unlock bootloader on any HBOOT and keep S-ON but if you want to S-OFF and unlock you have to downgrade from 2.x.x to lower HBOOT and use Revolutionary.Then you can change HBOOT as you wish but you can brick your phone if something goes wrong.
There's great guides here for everything so do a serach. GL
