Not too long ago, we brought you coverage of the HTC EVO 3D HBoot downgrade, which allowed users to finally rid themselves of HBoot 1.5 and achieve true s-off status. And as expected, it’s taken off like wildfire. Since then, users and developers alike have breathed new life into the HTC EVO 3D forums, as now users can do whatever they want to their phones.
However, there are still some out there who just aren’t as comfortable as they’d like, and haven’t gone through with the somewhat difficult procedure. While the concept of overly simplified tools is a hot topic here, there are some who believe that simplified tools are useful and even preferred over longer, potentially riskier solutions. To that end, XDA Forum Member closeone has created a tool that will the less facile go trough the process with minimal difficulty. It’s a bootable live CD that automates as much of the process as possible, leaving only the need for just a few simple terminal commands.
The Live CD, which has been updated several times and is has both a stable release and an experimental release, comes with very easy to follow instructions and a full FAQ from closeone on how to use it and exactly what work is involved on the side of the user. Users have reported that the Live CD works well and is significantly easier than the manual process.
According to XDA Member Advocate Admin and News Guru egzthunder1, it should be noted that there are some dangers associated with the Live CD.
The method will completely brick the 3D if you try to brick it while it is S-OFF. Apparently, emmc mode does not activate if you are S-OFF already, so corrupting the bootloader will only result in a permanent brick. Unknownforce added this to the OP on his guide.
So if you’re S-OFF do not, under any circumstances, attempt to use this method as it will cause you many irreversible problems.
For more information, download links, FAQ, discussion and more, check out the Live CD thread. Remember to be careful, as even simplified rooting methods carry an inherent risk.

HTC users occasionally have to use some interesting methods to flash what they want onto newer devices. From risky methods of downgrading their bootloader to applications that have to flash kernels, device hacking isn’t always straight forward. To help make this a bit easier, XDA Recognized Developer drellisdee has posted a tool that allows HTC owners to look at, and change, their Main Version.
The tool allows users to lower their Main Version to allow the flashing of older RUUs, which could help downgrade Android versions and HBoots if used properly. While originally intended for the HTC Rezound, this tool is compatible with other emmc-based HTC devices starting with the G2 / Desire-Z, and has been tested successfully on the Incredible 2. In the words of the developer:
This tool will allow reading and directly writing the main version in Htc’s misc partition to allow flashing if your main version is higher than the hboot/fastboot zip you are trying to flash or for the purpose of software downgrading on most HTC devices.
Device must be an emmc based HTC & you must have root.
This should work on all emmc based HTC devices G2 to current such as rezound. This tool has been tested on Incredible 2 and on Rezound.
The application itself is for Linux users only, but Recognized Developer con247 has implemented the program into a recovery-flashable update.zip. Eventually, drellisdee has plans to implement this into a custom recovery:
I will eventually have this included into my RA Revamped recovery lineup as time permits.
Those interested in getting started or checking out the source code should head over to the original thread. Just be sure to proceed with caution to not end up with an expensive and shiny paper weight.
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.
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.
