unbrick

Some of the Samsung Galaxy devices earned a reputation of being almost impossible to brick, which is of course not exactly true (although they are harder to brick than their HTC counterparts). It looks like the research for the perfect way of unbricking a Captivate has led XDA Recognized Developer AdamOutler to discover something rather interesting. With a few modifications to the OM pins, it seems that he has managed to get the device to become bootable via either USB, UART, or even MMC. In essenece the device can be revived no matter what you flash on it. It is quite a better and substantially cheaper alternative than having to send your device to Samsung, send it to a repair shop, or even cheaper than having to purchase a JTAG box for yourself.

The dev has provided a very well laid out guide on how to make this mod yourself. You will not need a whole lot of things, but you will need to have some firm pulse and some soldering skills. Other than that, if you are interested in making your Captivate immortal, you should definitely take a look at this.

I’m not kidding when I say UnBrickable. Modifying the OM pins means you can boot from USB, UART or MMC. This makes the phone quite UNBRICKABLE.

HackPack33hackingtools

Our devs spend countless hours and tons of blood, sweat, and tears in the process of gathering information and knowledge so that they can make our devices better. This is no easy task as you have to remember that manufacturers don’t always provide the documentation required to do half of the things that we normally do on our phones and tablets. In many rare occasions, the tech representatives from the manufacturers will have nothing themselves. So, where does one go to get this information? To answer your question and save you a ton of search time, XDA Recognized Developer AdamOutler has put together what he calls the “Galaxy Hack Pack”. The dev, as you may know from some of his work, has spent a tremendous amount of time researching into the Galaxy devices, particularly on unbricking methods such as JTAG and a few others, and has picked up a ton of useful utilities in the process. He has decided to compile all of this information and his findings about what apps are useful for hacking the Galaxy devices into a single thread. Please keep in mind that these tools are not for novice users since they can mess up your device beyond recovery if used incorrectly. Also, the dev states that because of this, he will not be walking people through the “how to use” each tool. Basically, if you cannot understand what each tool does from its description in the thread, you should probably not be messing with them.

If you have any additions that you would like to point out for this wonderful resource, please let the dev know.

However, you are here looking for the GalaxyS Hack Pack. During the last few months I’ve been collecting software and resources. This package contains everything known to help with research, investigation, security and hacking on GalaxyS phones and the Android platform. I’m not helping you root your phone, nor providing market applications. This package is not intended for new users.

oneclickunbrick

By this point in time, if you have been a member of this site for longer than a couple of years, you have witnessed rather complicated processes such as rooting and flashing, turned into easy 1 click procedures. These are normally fool proof and will let you get the most out of your devices while saving you a few hours of reading. However, there is always a risk of bricking your device. This is a time for you to sit down with a good cup of coffee and start reading because unbricking is a fairly complicated procedure that may require special hardware to get it accomplished (JTAG). It looks like this is a thing of the past for Captivate owners because XDA Recognized Developer AdamOutler just released a 1 click unbricking tool. The application is actually part of his Heimdall’s project and seems to work very well for various platforms including Linux.

The dev is looking for feedback on this tool. Please try it out and see if it works for you.

touchwiz-3-0-walkthrough-with-the-samsung-captivate-galaxy-s_1

If you’ve been following the work of XDA forum member xan‘s Voltage Control app, you might be interested to read about XDA member shane87‘s re-write of it, designed to work with Gingerbread based kernels.

Please note that the app is still in development and issues are currently being worked on.

Features of Control Freak include:

  • Designed for use with JVB/JVH/JVO based Gingerbread kernels
  • Specifically designed around features present in existz’s Talon kernel
  • Allows enable/disable specific states
  • Allows undervoltage control on a state-by-state basis
  • Allows limiting clock to a specific speed
  • Allows changing of governors
  • Allows control of CPU threshold settings
  • States enabled info is found by opening each UV control
  • Logs all major start up values as they are polled from the sysfs

For much more detailed information and to download Control Freak beta, head on over to the application thread.

system access in linux

The \system in Android is like a forbidden candy for many. A few people will only dare venture in the file and folder mess that represents that particular area of your devices. However, this is where all the fun usually happens. All settings, apks, everything that is of importance to us and to devs lies in there. However, getting there is not necessarily easy or cheap. There are programs like Root Explorer, which will allow you to do a whole bunch of things including mounting, copying, and doing some other fun actions, but as this is a paid program, one has to look for alternatives. Luckily, XDA member AdamOutler has posted a guide to perform all of the above functions and more by using a connection from your computer (whether you are running Windows or Linux), which will allow you to do things such as dual mount, wireless mount, open a wireless root shell, and much more. The guide is intended to give you unrestricted access to… well, everything in your device. As such, it also gives you enough tools to royally mess up your device. So, be careful when you are trying something. Also, remember that you must be rooted to try this out.

The guide is well detailed and gives you links to get all the stuff that you need to get started. Please leave some feedback for the dev.

Introduction:
Here is how you can obtain unrestricted file access to your phone.

Most of the time you don’t need to access the restricted areas of your phone. Sometimes it’s required. I like to use SSH/sftp as it is very compatible with everything.

Here are some of the benefeits of using this technique:

  • Dual mount ( you can copy to and from the phone while using the sdcard)
  • wireless mount (copy to your sdcard without cable)
  • wireless root shell (root terminal access)

You can find more information in the guide thread.

Thanks AdamOutler for the tip!

JTAG Custom

JTAG has been, since the early days of phones, the surefire (and in most cases) the only possible way to bring a device back to life after a flash gone wrong (used to be really common back in the WM days). Nowadays, Android devices are actually rather sturdy in the sense that you can flash virtually anything to these devices and would be easy to revive. This happens to be the case for a lot of Samsung Galaxy phones. However, there are still ways to turn your shinny Galaxy into a shinny paperweight. However, JTAG boxes are usually very expensive and you will likely not be able to make one yourself, or so we thought until we saw this thread made by XDA member AdamOutler. Apparently, the dev is rather familiar with electronics and has taken it upon himself to revive his dead Captivate. In this process, he created a very informative thread in which he includes a design for a circuit, which will enable this functionality. The key thing about this is that because of the proximity of the pin connectors, in order to make this, you had to have very good soldering skills. Thanks to a rather ingenious circuit design, this is no longer the case. The dev has also provided the most recent pin outs for you to try this out yourself.

Please look throughout the thread as it has tons of very useful information (and it is not a long read either with the thread being about 5 pages long). Trying this in your device may result in complete death of your device and even personal injury if you are not careful with a soldering iron. Please leave some feedback if this is of any use to you.

I think we may have a way to recover any phone with around $40 in hardware (including an Arduino ATmega, a 150Kohm resistor, and a micro usb cable) and no special skills aside from soldering to a USB cable…. Which is nowhere near as difficult as soldering to these microscopic connections.

I need to brick my phone in order to test my theories. If my theory is wrong, then I need to bring it back to life. JTAG, being a tried and true method will serve the purpose well. My plan is to brick my phone every which way from sunday and come up with ways to bring it back using the microusb cable. If I do something really crazy, then I need the JTAG backup.

UrV8g

This is a perfect example of a program that just works and does its job. This desktop program made by XDA member bay_wolf gathers all basic utilities and puts them in one place, including all steps from root to installing custom ROMs. So, if you’re a beginner Samsung Captivate user and would like to get more out of your phone, simply download this tool and follow every step. You can also sideload apps from this program. You don’t have to use more than 6 programs to do all of this – everything is now available in one place.

Most of the instructions are given to you by the program and are not needed to be written out here. If you find any part confusing, please comment in this thread and I’ll try to implement it in the next release and I’ll tell you what it means as a temporary solution.

More information and the program itself can be found in the AIO Captivate Toolbox thread.

RomKitchen

We, as News Writers, must have somehow missed this thread about an awesome online kitchen by XDA members DocRambone and Stefunel. It gives users the ability to select their own resources to put their own Galaxy S or Captivate ROM together. Figuratively, you can see it as a menu card: you can choose between several flavors and dishes, those that fit your taste. So, for example, you want a Dutch ROM with Supercurio’s kernel, a special boot animation and a good-looking theme; you simply select every option and in the end, the site will offer you a download link to the ROM, generated according to the options you have requested.

  • An easy way to generate custom roms
  • Create a rom from your mobile browser
  • Stable and fast base roms
  • Choose the components you like is your rom, without any additional add-ons

We must however note that, if you’re a novice user, you will probably have to investigate in the whole Android development world with all its jargon.
The kitchen can be found over at romkitchen.org. It’s absolutely an innovative and new alternative to the usual ROMs that are being provided by the chefs. So we’re really wondering what will happen with good old ROM chefs and the way we were used to download ROMs and test them – we guess this must be another symptom of ORD, we are almost having a nostalgic feeling about it. We’ll see what the future brings.

Back Camera

Are you bored with the look of your Samsung Captivate? Fancy a subtle change? Why not try out XDA forum member geokhentix‘s ‘mod’?

We say mod, but it all started out as an accident – the XDA member, holding a knife in one hand and the Captivate in the other, accidentally knifed his phone, revealing a flash of silver under the black speaker.

After that, there was no way back and the only thing the XDA member thought to do was to scratch off the remaining black plastic.

For the full rather wittingly told story, and to check out other members efforts, head on over to the ‘modification’ thread.

Samsung-Galasy-S-vs-Samsung-Captivate

SpeedMod, probably the most popular kernel originally developed for the Samsung Galaxy S, is now available for the AT&T Captivate too. XDA member hardcore, the developer of SpeedMod, decided to create the same kind of kernel for the Captivate.
The developer’s aim is to have a kernel that is fast, compatible, stable, and with good battery life. It contains many custom features:

Originally posted by hardcore

- Based on JPX Android 2.2.1 kernel source
- Works on all stock Froyo 2.2 and 2.2.1 ROMs and popular custom ROMs
339MB RAM and all features should work
- Enhanced version of sztupy’s Universal Lagfix
- Includes neldar’s BackLightNotification 2.3 from https://github.com/project-voodoo/ba…ernel_patches/
Sharpness & color fix for UI, inspired by supercurio’s work on Voodoo
- SpeedMod: Replaced kernel jhash2 with jhash3
- Includes my Startup Tweaks from http://forum.xda-developers.com/showthread.php?t=813309
- Adjusted kernel HZ value to (hopefully) balance battery life & smoothness
- Uses BFQ IO scheduler by default, from http://algo.ing.unimo.it/people/paol…ed/sources.php
Updated ext4 code in kernel from http://www2.kernel.org/pub/linux/ker…/ext4-patches/
- Properly working Tiny RCU patch for better speed and efficiency from http://android.git.kernel.org/?p=ker…90160a18caf95d
- Optimized compiler flags: -O3 -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp

Don’t worry if you don’t understand most of this – we can tell you now that the kernel is really good.
Yet, be sure that you know how to flash kernels to your phone. Otherwise, it would be a good idea to investigate further before doing things that could brick your phone.
Check out the thread for more information and download the kernel.
