In light of HTC’s persistent refusal to give in, and stop wasting their customers’ money on their failed attempts to lock down bootloaders, it is rather pleasing to note that the Revolutionary team has made its return to the HTC One forums, to present their early-access developer preview of Revone.
Posted by XDA Recognized Developer ieftm, it appears the Revolutionary team have been busy once again. The current tool is clearly labelled as an early access preview, and it is worth heeding the warnings. That said, this appears ready to use if you have suitable experience in working with command line tools such as adb and fastboot.
The exploit takes the form of a single binary, which is pushed to /data/local/tmp (a location where the user has free access to write files to using the adb service, and execute them from within), and run the prepare command (revone -P) in order to prepare the device for the process of gaining S-OFF. The next step is arguably of most interest, where the bootloader can be unlocked, locked (without setting the re-locked flag), relocked (leaving the relocked flag in place), and the tamper flag can be reset.
With the ability to reset flags like the tamper flag, one really must question the usefulness of such a “security” feature. If it can be reset solely using software, does it offer much protection whatsoever? Bootloader locks are a useful security feature when they can only be removed by the legitimate owner, but unfortunately HTC continues to offer incomplete locks to developers, and the community has once again taken it upon itself to right this.
Do bootloader locks help with device security, or do they simply serve to satisfy controlling carriers’ thirst to exert control over devices on their network? Either way in this case, it is clear the Revolutionary team has shown they offer little in the way of security. Those looking to get started should head over to the development thread for more details.

HBoot in HTC devices is central to the overall development experience, especially if you intend on rooting and unlocking the bootloader your device. However, bootloaders aren’t just for unlocking or flashing RUUs to get back to stock. They can actually be useful for a variety of other things. XDA Senior Member dla5244 has released a beta of a custom HBoot version 2.00 named Blackrose, which is available for anyone who’s rocking a HTC Incredible S.
In order to get started, your current HBoot must be S-Off. Blackrose is feature packed and includes things that you cannot get in a typical HBoot. The features includes:
Removed oem lock, unlock command(because there is no need to unlock)
*.I will release new BlackRose after Official ICS release(I think hboot will be changed)
Feature – Nexus One BlackRose (Just Reference)
None padlock mark even unlocked
BlackRose custom command
Change boot logo
Select menu by pressing trackball
Switch vibration at boot
CRC32 check function
Prevent overwrite HBOOT by RUU
The installation of the HBoot is pretty easy, simply, plug the phone into a PC with USB Debugging on (charging only) and run the install.bat file. To revert, plug it back in and run the uninstall.bat.
If your Incredible S already is S-Off and you want to give it a shot, you can find all information you need in the original thread. Keep in mind that you are flashing bootloaders, so there is the potential for your phone to get pretty messed up. Proceed with caution.
The well known website www.htcdev.com is slowly becoming the go to website for HTC users who want to unlock their bootloaders and get s-off on their bootloaders. However, sometimes there are easier ways for people who don’t want to register their device with HTCdev and want to have the option to retain their warranty.
It is with this in mind that XDA Member shadi22 has posted a method that allows users carrying the HTC Desire S to downgrade from the latest hboot version so that they can attain s-off without all the hassle of the website.
The tools required are easy to obtain and include:
2.misc_version (download attachments below)
3.OLDEST RUU for your “REGION/ BRAND”.. i repeat, specific region to avoid customer ID error.
4. adb (you know how it works)
5. phone in USB debugging mode.
The process is a tad complicated and requires using ADB, so be sure that if you give this tutorial a shot that you carefully read the instructions and follow them. Once everything is flashed properly, then it’s just a matter of running over to revolutionary.io and using the tried and true s-off method.
For those carrying the HTC Desire S and want some s-off goodness, check out the original thread for downloads, full instructions and all your s-off needs. Once you’re rooted and s-off, don’t forget to make that backup before you go flashing anything.
As they say, the real fun doesn’t start until your device gets root and s-off and that’s certainly the case with the HTC Jetstream. The device got root just a couple days ago and the modders and developers have gone to work making the already great device even greater.
XDA Senior Member Giblet-dono has drawn up a quick tutorial that will give your HTC Jetstream the ability to make and receive phone calls over a 3g GSM network. According to Giblet-dono, all you need to get started is:
S-Off (get yours from HTCDev soon!)
Root (get yours from DoomLord)
That seems like a very short and easy list of pre-requisites. Based on the instructions, it seems just as easy as editing your build.prop file which doesn’t carry a whole lot of risk, so if this sounds like you’d like to try out then head on over to the original thread for the full instructions.
Additionally, Giblet-dono is also working on making messaging work and the up-to-date troubleshooting for it is going on right now in the same thread. It won’t be long until you can use your Jetstream as a fully functional phone. A very large, very awesome phone.

Livven has already talked about the Honeycomb update and you can find the article right here .
If you take a stroll down XDA way and take a gander at this thread you can check out this early release of s-off instructions.
As globatron states in the thread,
This is an early version of the S-OFF procedure intended for experienced modders / developers not for general users, if you are neither of these, then it is not intended for you at this time.
So, as the warning states, unless you’re an experienced developer then you should probably stay away from this for the time being. However, this is the official “first step” in getting s-off, root and recovery to all Honeycomb-toting HTC Evo View users.
Despite not being a public release, it is encouraging to see that people are on the job and finding ways around the new framework and we’re sure there will be a public release very soon. Until then, though, you’ll have to keep tabs on the thread from the link above to keep up to date with the HTC View’s Honeycomb rooted goodness!
S-OFF. Those five characters represent the world to power users. They represent the ability to do whatever you want, whenever you want, without the OEM holding you down.
For many a GSM EVO 3D user, those few characters seemed unattainable. HTC had locked the HBOOT and downgrading seemed impossible. As the months passed, hope seemed lost…
Fortunately for them, a clever chap by the name of navrasis refused to give in. After much research he cracked the code, err…blocks in this case. You see with a little creativity (and a hex editor) he managed to beat the system. See for yourself here.
A word of caution though, this mod is not for the faint of heart. Any time you mess with things on such a low level, you take a chance of bricking your device.
So rejoice EVO 3D users: you won.
