For both developers working on HTC devices and the end users wishing to get the most from them, achieving S-OFF is one of the major stumbling blocks that stands in the way of a fully customizable device. To sum it up as simply as possible, the S stands for security and achieving S-OFF is the process of unlocking the devices NAND storage. S-OFF is usually achieved sooner or later for the majority of HTCs devices. However, sometimes it can take a while to get there. One of the most recent devices to join this club is the HTC Jetstream, thanks to the rather bizarrely named Juopunutbear utility.
XDA Recognised Developer Fuses posted news of the Jetstream becoming a supported device for this tool earlier in the week, and it now sits alongside other popular HTC devices such as the Amaze, Sensation and Evo 3D (CDMA/GSM) among others. While the process is pretty simple on paper, something like this always has the potential to go wrong. Make sure you read up and understand the risks/potential problems before attempting this yourself. You will also need to have your bootloader unlocked via HTC Dev before trying this out.
Take a look at the original development thread for more details, as well as a link to find out exactly how to pronounce “Juopunutbear.”
basically this should encourage other devs to start working on the device now that they know its rooted, has recovery and can run custom kernels
The kernel itself seems pretty on par with DooMLoRD’s other kernel work, which is to say it’s loaded with features and is just all around awesome. Some of the features include:
CPU overclocked to 2.052 Ghz
CPU underclocked to 192 Mhz
GPU overclocked to 320 Mhz
for safe booting CPU is capped at bootup to 1.536GHz/384MHz (max/min)
slightly undervolted (atleast for stock frequencies)
uses LZMA compression
added lots of fixing/patches (including CPU HOTPLUG notifications/CPU unaligned access) thanks to faux132
VDD CPU voltage control (@ /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels)
compiled using Snapdragon optimizations
enabled few file systems support:
insecure kernel (ro.secure=0 & USB debugging enabled by default)
/system mounted as RW
Did anyone else notice the 2.052 GHz overclock capability on the CPU?
For those lucky enough to be carrying an HTC Jetstream who wants to check out this awesome kernel, you can find the full feature list, instructions, shout outs and download links in the original thread. The installation instructions aren’t hard to follow, but if you’re not familiar with the Fastboot on this device, you should probably should be before attempting to flash the kernel.
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.
Well the development didn’t stop there. The reportedly sexy (in a non-threatening Johnny Depp sort of way) XDA Recognized Developer DooMLoRD, who not only brought root to the device, has also now released a custom recovery for the device as well.
And did so without even owning the tablet. Mad props.
The recovery is a heavily modified ClockworkMod 5 release with everything you loved about ClockworkMod recovery plus a few extras, including:
changes to graphics (ported some graphics from CWM5.5 ICS edition)
revamped layout for recovery menu (to improve navigation) [renamed few options and changed their order]
changed “wipe data/factory reset” option to just “factory reset”, and detailed the partitions which will be wiped
added reboot options
Now, as DooMLoRD notes, this is still in the testing phase so before doing anything drastic, be sure to back up your current system! He also notes:
currently this recovery doesnt allow u to flash/backup/restore the boot and recovery partitions… thats because i was not able to find the device block associated with those partitions… if u know wht partitions are mapped to /boot and /recovery do let me know and i will add that feature asap!
So, as with any work in progress, tread with caution. However, if you want to check out all the details, instructions, the full changelog and downloads you can find all that and more in the original thread found here.
The incredibly well known and super successful (and possibly super handsome…we don’t know for sure) XDA Recognized Developer DoomLoRD has finally brought that sweet, sweet root goodness to those who have long awaited it on the HTC Jetstream.
The root process is simple enough. Simply download DooMLoRD’s Easy Rooting Toolkit, place it in the root directory of your computer and press play. Here’s the basic instructions as he puts them:
then download the v02 toolkit for JetStream files and extract contents in root directory of ur pc (e.g: c:\ OR d:\)
then just connect device (with my insecure kernel on it) and activate USB debugging…
then execute RUNME.bat
ur device should now be permanently rooted after reboot…
So there you have it. It’s easier than most one-click root methods out there, but as with any root method it could cause serious damage so make sure you proceed with caution. As DooMLoRD mentiones, it’s still in the testing phase and once he gets a few more people to successfull root their device with it, he’ll be posting it in the HTC Jetstream Development Section.
So if you have your HTC Jetstream handy and want to take a swing at rooting it, follow this link for additional information, instructions and download links or this link if you want to read the whole thread leading up to it.

Just when you thought that we had had it with forum additions on this site, we go ahead and give you more places to play around here. In this last induction of devices into the XDA family, we are bringing one of each flavour… err, manufacturer. First, we added the Sony Xperia Neo, the latest one of the newly released Xperia family, which is a rather standard device for this day and age equipped with a 1 GHz processor, 512 MB ram, 3.7 in screen, and every possible lock that Sony can put in the bootloader (calling for devs… wink, wink). Next up we have the LG Thrill 4G, which is LG’s next iteration of 3D camera equipped devices. This one is indeed fully loaded with a full HD video out (1080p), Gingerbread, a 4.3 in screen, and did we mention the 3D camera? Last but not least, the HTC Jetstream (also known as the HTC Puccini). This will be running in the AT&T’s network in the US and sports quite an interesting package: 1.5 GHz processor, Honeycomb 3.1 (a first for HTC), a 10.1 in screen, a 1200×800 display, and Sense which is something that has been in the minds of a lot of early Honeycomb adopters.
If you have your hands on any of these devices and would like to leave a few reviews, or if you discovered something interesting about any of them, make sure that you visit the newly created fora.
You can find the Sony Xperia Neo forum here.
You can find the LG Thrill 4G forum here.
You can find the HTC Jetstream forum here.
