The Samsung Captivate is a great device for the budget market, but the software updates are limited by the manufacturer, Android, and the phone carrier networks that deliver them. That means there’s little to do after you get to know the current features you have in the version of Gingerbread. There is one glimmer of hope and that’s with opening up the internals with root access and a custom recovery image.

Only then can you start installing custom ROMS and get further enhancement of the OS. If you find there aren’t many ROMS available from third-party developers, you can still enjoy a number of third-party apps available from the Google Play store. With these applications, you can overclock the CPU to improve performance, improve battery life, remove bloatware for extra performance and more.


  • You must have the device running Android 2.3.5 Gingerbread. You can check what version of Android your operating system is running by navigating to Settings > About Device.
  • You must have a Windows computer. You cannot use a Mac OS X or Linux because we are using the Odin tool. The Samsung developers only use Windows for the tool.
  • You don’t have to worry about reserving most of your battery because the USB charging will take over once plugged into the computer.
  • You are flashing a custom kernel on your device. The kernel we are using is the corn kernel. Those who don’t want a new kernel shouldn’t go ahead with the installation.
  • The following comes with a warning for all users. Some people strike issues when flashing the files. We do not recommend installing this on your daily drive just in case your device doesn’t work like it once did.


1. Download the CornKernel_UCKK4_v705.tar

2. Download the Odin 1.85.rar

3. Extract the Odin folder to the desktop.

4. Start the executable Odin file, so it’s running on the computer.

5. Boot the Captivate in Download Mode.

6. Connect the smartphone to the computer with the USB cable.

7. Wait for Odin to pick up your device and change the ID: COM port color.

8. Click the PDA button and upload the cornkernel tar file.

9. Leave all other settings inside Odin as default.

10. Do not check the re-partition box.

11. Click the start button and hope for the best.

Now you have root access and a custom recovery image installed on your Sammy Captivate, you can start flashing all the custom goodies available. That can either be reference to custom ROMs—if there are any—or root files such as Chainfire’s SuperSU. Sometimes people get root access by flashing something along the lines of SuperSU from the custom recovery image itself. It’s very common outside of one-click rooting methods.

The custom recovery image can also be used for directly uploading custom ROM files. Not all devices have custom ROMs though so you’ll need to hit up the XDA-Developers forum and see if there are any. You can use the search box on that website to browse for your smartphone and then read the existing Android development section to see if any ROMs are available. You flash the ROM file the same way you flash the SuperSU. You should have no trouble finding an abundance of guides out there that can help you with the steps for that. The method for installing a custom ROM from a custom recovery image, regardless of the custom recovery image of choice, is a universal one, meaning that it’s always the same process involved.
