So you love the Titanium X ROM on the Samsung Moment, but want to move to a different phone, or switch services and still keep the tremendous support, and power that this ROM has? Well don’t worry, the future of Titanium X is to expand and blanket many different Android phones. If you didn’t figure it out from the title of this post, we’re branching out to the following phones in the not so distant future.

Samsung EPIC
HTC EVO
HTC HERO
Motorola DROID

Making the total number of phones five. Currently there are builds in testing for the Droid, and Hero.

It just sends tingles down your spine doesn’t it?

So you’re curious about the two main versions of Titanium X or other such ROM’s that provide you these options… Well, it’s not outrageously complicated, but something that isn’t widely known. “JIT” stands for Just In Time, it is a technique for improving the runtime performance of a computer program.

What does this mean?

It means that your phone will take a hybrid approach towards processing code.

And that means?

It means that JIT will compile some or all of the bytecode into native machine code, with both interpreted and static methods.

So what does all of that mean then?

It means that your phone will run noticeably faster then it would running the stock rom or Non-JIT roms.

How much faster?

While JIT is still relatively new for use on phones, at this time we’ve seen improvements of nearly 4 times that of stock setups. While typically seeing 2 times the power of current Non-JIT (running ARM11 lib files). So overall, you will see your phone operate much more quickly using JIT.

So why would people choose Non-JIT over JIT builds?

While the performance is outstanding using JIT, at this time it’s still being researched and developed so there can be some stability issues that come from using JIT builds. While overtime JIT will become stable and reliable, at this time you may see random reboots depending on your use or setup. At the time of writing this article, the current version that has proven to be the most stable is JIT 3.1  from developer noobl. To show that not all versions are quite up to par, the current version as of this article is version 6.1.

Another thing you may want to think about when deciding on using JIT or Non-JIT is the battery life. While no major tests have been performed to really measure the impact on battery life that JIT may have, the traditional theory is that due to JIT improving the performance in speed on your phone, you will use more power to feed that performance. Much like adding horsepower to your vehicle. The more horsepower you add from upgrades, the more gas your vehicle will use.

So should I use JIT at this time?

Sure, why not? The whole point of rooting your phone is to try to get the most out of it. JIT is definitely the way to do that. With better performance gushing out of it then most people would know what to do with, I think you’ll be satisfied overall. Just make sure you find out what the most stable release to date is and start from there.

When you’re messing with boot animations, the Samsung moment is not your friend. The wrong size, the wrong layout and the wrong dimensions, can easily turn your fully working phone into a brick. But not all is lost, you can recover from “bricking” your phone. Thankfully we have ODIN.  It’s not ideal, but can quite easily spare you from having to come up with some explanation while you head to the Sprint store to get your phone replaced. Here’s how.

What you can do with ODIN?

There are 3 different things that we are currently flashing that have to be flashed separately:

• ZExx Kernels (ZE11 is most current)
• The CL14 system update

Note: The following Sprint apps have been removed: Bejeweled Demo, Sprint Nascar, Sprint NFL, SprintTV widget.

• The CL14 modem

Prerequisite programs

You must have Odin 3.98 & moment.ops, which you need to extract the files with WinRAR or 7-Zip. This process will not work under Vista SP1, it requires SP2 or higher. (not sure about XP)

Flashing process

Once you have these 2 necessary pieces you are ready to begin:

You must disable PC Studio in you task manager before you do the following

1. Turn off the Samsung Moment (totally off.. hold power button and select power off)
2. Once the device is fully powered off, disconnect the USB cable.. Hold down the volume down button and camera button.. Then push and hold down the power button to turn the phone back on.. It should go into a screen with a giant blue disk and arrow and say Downloading… DO NOT TURN OFF TARGET!!! (You can pull the battery to exit this screen without causing harm to the phone. Just do not pull the battery or cable once you actually start a flash and it is uploading the files)
3. Plug in the USB cable to the moment and your computer and make sure you are online Windows will attempt to download the drivers from the web.
   1. This is the step that might cause some problems
   2. If the driver installations are not successful. You will need to manually update the “G” and “USB Composite Device” drivers manually:
      1. Open Device Manager.
      2. You should see 2 devices with yellow triangles that need updated drivers “G” and “USB Composite Device”.
      3. Both of their drivers are located within the Samsung PC Studio 3 install directory, C:\Program Files (x86)\Samsung\Samsung PC Studio 3\USB Drivers\3. Download PC Studio Here
      4. Tell Device Manager to look in that folder for both the “G” and “USB Composite” drivers.
4. Right click Odin_Multi_Downloader_v3.98.exe and Run as administrator
   1. The first box at the top left should say Detected (this means Odin sees your phone in Download Mode)
   2. Go to Option and check the box that says One Package
   3. Go to Select Ops and hit the button labeled OPS and find and select Moment.OPS
   4. Below that at the bottom it should say Select Integrated Package
   5. Check One Package Option
   6. Select the OnePackage button
   7. Find and select SPH-M900_ZExx.xx_KERN.TAR
      1. Do Not Touch SPH-M900_CL14_MR.7z It will make it harder for you to flash in the future.

         Note: The ZExx.xx will change depending on which version zefie is on. This is also where you would select the .tar file for the system & modem upgrades.

5. Press the start button and it should begin to flash

   *Reboot the phone and once the phone is back in android you can unplug everything and close odin…

   Note: The download file for cj05 and zefie‘s kernels will be in a .7z compression DO NOT USE WINZIP TO UNZIP THIS. Use 7-zip. Once you get the .tar file Do not change this file in any way.

   
   

   Thanks goes to SDX for creating making the wiki for this overall process located here: http://wiki.sdx-developers.com/index.php/Flashing_with_ODIN

Well, as some of you might have seen, Titanium X versions went into the 1.2.X level. I’m going to explain what these levels mean for us. So in order to make this easy to understand we’re going to name the levels A.B.C.

A = Major code release changes (typically substantial enough to justify a version change IE: Graphics, slimming etc)

B = Sub code changes for multiple features (IE: JIT, CDMA fix, kernel, etc.)

C = Addition, Update, or Removal of applications to build.

For instance, while at version 1.2 there was a high demand for the Visual Voicemail, On-Screen Keyboard, and Street feature to be added back in. Therefore, we added a 1 at the end making it 1.2.1.

To some of you, this is quite common and to be expected. Typically we do not like to make changes like this frequently as we don’t want our users to feel that their ROM they just built last night is already obsolete. However, it’s bound to happen as we want to fix problems, add highly demanded features back, or improve the version.

I will try to keep www.ti-x.com up to date with the latest version posted on the front page, as well as in the forums for everyone to keep track of. But you will always be able to see what changed to make the new version what it is.
