[Q] Rooting HTC Sensation without flashing custom ROM

Hi, is it possible to root the HTC Sensation without flashing custom rom? Because all the methods I saw around was flashing roms. If possible, is it permanent root(cause I heard about temp root)?
I want to stick to HTC's stock rom. Also need to mention that, currently I'm not owing any Android phone, but will must buy HTC Sensation.
(pardon me if my words sound like noob, cause I'm really a noob)

You don't have to flash a rom. You just proceed with the revolutionary s-off method and then flash the signed super user zip as indicated and enjoy your stock HTC rom while still being s-off and rooted. They just say things about flashing roms because those are the intentions of most people who s-off. But no worries, you'll be able to enjoy stock just fine.

Thanks. I was worried about it.
However do you have any best link for this guide regarding to my purpose?
I think the guides at http://forum.xda-developers.com/showthread.php?t=1192300 and http://forum.xda-developers.com/showthread.php?p=16125079 are great for me?

[Q] A couple of questions concerning new Desire S

hey there,
bought my gf a desire s to christmas. i, as a sensation user at the moment am very comfortable with development. flashing, adb, fastboot and things like that are working flawless.
as i don't have so much time to read atm, i have some questions concerning the way to set the desire s up. it was shipped with 1.47 rom, t-mobile branded, sense 2.1, android 2.3.1 and hboot 0.98.0002
i want to flash this rom: endymion sense v3.1 (android 2.3.5, sense 3.5)
i already achieved s-off with revolutionary, hboot is now 6.98.1002 with radio 3805.06.02.03_M. 4ext recovery 2.2.7RC5 is installed as well.
now i saw, that there is RUU_Saga_S_HTC_Europe_2.10.401.8_Radio_20.4801.30.0822U_3822.10.08.04_M_release_225161_signed.exe availble. i also read in the forum, that this ota brings some parts for firmware, which are not flashed with a custom rom.
so would you recommend to flash this ruu first? wouldn't i lose s-off then? would i be abled to achieve s-off again after flashing this? also, for my sensation i would have to supercid first - i didn't read about this here in the forums.
what i would want to do:
1. flash RUU_Saga_S_HTC_Europe_2.10.401.8_Radio_20.4801.30.0822U_3822.10.08.04_M_release_225161_signed.exe
2. run revolutionary again
3. flash custom recovery
4. flash endymion v3.1
would it be possible this way? or would you recommend any other way to me? i want to have all firmware parts as up to date as possible before i flash the custom rom.

Cause you are already s-off I would say it's senseless to use the ruu first, because it would put you back to s-on like you suggested, but only if the revolutionary bootloader doesn't make problems.
There are many reports of problems with it and I would say you should replace it with the 2.00.2002 engineer bootloader.
before just flash a custom recovery (I would recommend 4ext touch) and if your done with the bootloader flash the ROM of your choice.
To get bootloader, recovery,... just look at the index thread at the development section, it's all in there.
The last step to achieve a full upgraded phone would be to update the radio to the latest version, this you will also find at the index thread.
Happy modding
Oh and welcome, sry^^

is there a guide you are referring to? i already got 4ext recovery installed, but i don't find any post concerning 2.00.2002 bootloader. if i flash this one i would stay s-off? and it would bring me all parts which i would be missing without 2.10.401.8 RUU?

now i found this one, you are referring to that?

i guess you are referring to this? 20.4801.30.0822U_3822.10.08.04 with my sensation i would also have to flash a matching ril, isn't it recommended with desire s?

Yes this guide is to "downgrade" (in fact it's an upgrade, even if the version number is lower).
Yes you would stay s-off.
No it not brings you all what is missing, just a part of it, the rest you get with flashing the radio and the rom.

It's not really needed, you can do it if it's in the zip (or better said if it's there it's done at the flashing procedure), but you're also good to go without it.

htcdev unlock vs S-OFF / downgrade

Hello,
i am totally newbie here. Spent last 2 nights studying forum threads, but im still confused.
What is better to unlock via htcdev and remain S-ON and HBOOT 2.00.0002 or to downgrade HBOOT ?
I would like to tryout AOKP, Cyanogen and Fallout roms. Alternatively i want to try official ICS ASAP.

Unlocking via HTCdev leaves the phone S-ON. Therefore you always have to flash the the kernel (boot.IMG) from a PC via FASTBOOT when you flash a new rom with a different base. E.G. CM and Fallout. If the base hasn't change you don't need to.
If you downgrade and S-OFF your device you don't have to do that. Plus you can flash different radios (barely necessary).
HTCdev unlock is easier to do and gives you a lot of possibilities.
S-OFF is a little more advanced and there is a little more danger to brick your phone when you don't do it carefully.
Nevertheless I prefer the hard way since HTCdev is not the way I would go. Plus HTC knows that my device is unlocked.

Agreed. Although if you're changing ROMs often then HTCDev is not the easier way. Flashing the boot.img can be quite a pain if you're doing it often.

There was a nice text about that in another thread.

Ok,
so what you guys are basically saying is, that when i unlock my phone thru HTC-Dev, the company knows about it.
From this point of view, it's better to downgrade hboot and S-OFF.
I have one more question - if original ICS for DS will be realeased, how can i install it ? Do i have to revert to original hboot and original sense rom to find the update and install then ?

You'll find it here ...

Finally i temprooted this way
Zergush & misc - to temp root and prepare phone to be downgrade
Downgrade to RUU with 0.98.0000
S-OFF & install ClockWorkMod Recovery
Install Cyanogen 7.2
As rom i chose Cyanogenmod 7.2 stable. I am unexperienced with custom roms and dont want to be disappointed by semi-functional ICS roms by now.

If you're going for gingerbread take a look at reaper as well. It's basically a much faster version of CM7

For now, i am going to stick with ginger till the kernel will be released and the roms fully functional.
In future i would like to test ICS roms, but after new kernel. And of course Jelly Bean, if someone port it.
Basically if i want to change ROM, i just put it in root of SDcard, boot revolutionary, wipe and install from ZIP ? Is that simple now, after S-OFF ?
Thanx for the tip to check out reaper, btw

Yep that's all you need to do. I have to say though don't be afraid to just make a backup of your current ROM in CWM and try out other things.

Dan-fish, thanks for all your help
But i have one more question. What is all that mess around eMMC chip ? How can it happen to me ? Often flashing, installing from zip or ?

No the most common reason is pulling the battery out while the phone is on.

Dear remusator..
I'm trying downgrade hboot from 2.00.0002 to 0.98.00000 but I could not.
Can you explane how you make downgrade?
My device is "UNLOCKED"
Hboot - 2.00.0002
RADIO - 3822.10.08.04_M
eMMC - boot
Thanks..

Mine was locked. Check the first post. I didn't unlock via htc dev, maybe that's the problem.
I followed these tutorials :
1, Downgrade ruu and hboot to make root possible
sw 2.10<= http://forum.xda-developers.com/showthread.php?t=1399331
sw 2.11>=http://forum.xda-developers.com/showthread.php?t=1443636
2, S-OFF
http://forum.xda-developers.com/showthread.php?t=1186401
section How To: S-Off your device with Revolutionary: S-OFF & Recovery Tool (For HBOOT 0.98.0000, 0.98.0002)
3, Choose rom you like and flash via recovery. First i tried was cyanogenmod 7,2. Then i made backup, wiped again and installed AOKP. I'm not going back )
While browsing forums, i found topic about downgrading while UNLOCKED. Search forums, i can't find it anymore.
Btw, check your software version - tutorials differ from sw version.
PS: don't be afraid. In my case, everything went just fine.

Stock Rom needed
Hi remusator, which stock ROM did you use?
I'm mostly finding a lot of dead links and very few live ones for stock Desire S Roms.

I have used quite - Fallout / AOKP / Cyanogen 7.2
But i returned back to Stock. I used pre-rooted. I don't need root at the moment, but the prerooted rom can run on custom bootloader.
I use 2.10.401.9 sw version, take a look here
http://forum.xda-developers.com/showthread.php?t=1480576
Before root my official rom was 2.10.401.8 - but the link here on forum is dead, so i decided to use newer 2.10.401.9 instead. I haven't found any bug yet. It seems to work fine.

2.10.401.9 contains a minor bugfix for the Russian region. I doubt that you will notice any significant difference compared to 2.10.401.8

Re-engineered HBOOT 2.00.002 and ICS.

Hi, guys, first of all I'm an absolute noob so bear with me if I didn't found all the answer even after having searched through the forum.
My big question is about the re-engineered HBOOT 2.00.002. I have a virginal Desire S, non s-off'ed and non rooted, HBOOT is the latest, that is 2.00.002. I want to load the latest official ICS rom from htc and, as I think I understood, HBOOT must be latest version, therefore non s-off since there is no way to s-off that version. But I also would like to just go to CM10 in the future.
Then I read about the re-engineered HBOOT 2.00.002. This HBOOT should give me s-off and the ability to load the ruu rom. Only catch is that you should re-partition the phone. And that's when things get weird. Does I need to do the re-partitioning before installing the ruu ICS rom after installing the re-engineered HBOOT? If so, in order to install the ruu ICS rom, does I need to have any working rom on the phone, that is, does I need to do the nandroid backup to have back my ginger bread 2.3.5 before installing the ruu ics rom?
And going on, currently there is any way to root the phone while on ICS htc stock rom?
But most important of all, what this re-enginnered hboot really is? The revoked/revolutionary mod only works on hboot versions before the 2.xxxx. Is this re-engineered hboot a 2.00.002 official hboot that has been modified to be s-off or is it a previous hboot s-off'ed via revolution but with a different version number?
Thank you all,
Vincent.

If I was you I would forget about the re-engineered HBOOT and just run the RUU and put ICS on your phone.
The re-engineered HBOOT is only for people who have S-Offed using the revolutionary method and have had trouble with the Android 4.0 Sense ROMs. You have absolutely no need to use it now.
If you want CM10 in the future then all you need to do is unlock your bootloader with htcdev, flash a new recovery (4EXT or CWM) and install CM10 from your custom recovery. You will be required to flash the boot.img file separately if you are S-On.

Hi Kavrocks, thank for your prompt answer. I'll surely follow your advice, it's the easiest way and my first goal is to get an easy ICS on my phone. My only doubt is about being able to get to cm10 or whatever else since no rooting hack has already been developed for the new ICS rom.
Do you think HTC will push updates on the new ICS rom or, being it for developer only, it will be just stuck to its original state?

Original.

By what I understand, now that an official ICS ROM is out and thus binary drivers are available, we should expect a fully working non-original ROM in a short time. How much time do you think it will take for the CMx developer to integrate the binaries into the CMx ROM?

Don't tell this my Desire S, HBOOT 2.00.002, S-ON, unlocked with stock ICS and root
Just do this:
- unlock your phone: www.htcdev.com
- Install stock ICS
- install a custom recovery using fastboot
- install superuser using custom recovery

Ok, I've succesfully got ICS on my Desire, eventhough I had to do a 'fastboot oem lock' to get past a 155 error. Now, would you please be so kind to tell me the exact filename of the superuser exploit that you have applied on ICS? I'm asking this to you because I've tried the 3.1.3 on GB2.3.5 and it always hang on 'waiting root access right'.
Thank you.
Vincenzo.

How to install custom roms?

Hey. I just got a Verizon M8, and I was looking into installing some custom roms. The main rom that I want to install is a port of Android 6.0 from the GPE. It says that I wouldn't need S-Off to install, as to be honest, IDK what that is.
Anyways, how would I go about installing that rom since I wouldn't need S-OFF?

Well...unless your phone is already boot loader unlocked you sir will need s-off. Verizon doesn't allow us to unlock boot loaders like every other carrier out there.
Start @ http://theroot.ninja
And once s-off/unlocked you will be able to flash custom roms. The roms you saw say don't require s-off are based on phone carriers where unlocked bootloaders are allowed.
