I followed my own guide! This works perfectly if you read everything and follow the instructions.
Also: once you are rooted, be EXTREMELY careful! Half of the new threads are people who have screwed up their phones by deleting this or corrupting that. Please, for the sanity of all of the devs and Android veterans, make backups and just be all around careful. Almost all problems that anyone has had are repareable AND PREVENTABLE with a little reading and care. Just to clarify, rooting does not automatically enable sideloading. Please follow http://forum.xda-developers.com/showthread.php?t=738376 to enable sideloading.
Follow these steps exactly and there will be no risk of bricking your Captivate, the worst that may happen is the phone rejecting the update.zip.
I take no responsibility if ANYTHING at all happens to your device that you don't like. Don't come crying to me if your brand new phone breaks in any way. Your warranty is also void, but you could have figured that out for yourself.
Now that that's over with, lets get to the fun bit. If you are on Windows, you can follow this procedure, or for TGA_Gunnman's one click root program (only on Windows), you can go ahead and skip to the bottom.
1) You may need Samsung drivers if you are on a PC, which you can learn about here: ADB Drivers at the Unlockr
For 64 bit Windows, you'll need these drivers: http://zedomax.com/blog/2010/07/14/s...iver-download/
Don't proceed until your phone is fully installed on Windows with the drivers!
2) Download the attached zip (at the bottom of the post) and rename it to update or update.zip if you are on a Mac. (If you are on a Mac, DO NOT USE SAFARI to download the file, it automatically unzips any zip file. Use Google Chrome or firefox instead.) Scroll down the notification bar and click "mount" to allow your computer to read the internal memory. Put the file on the INTERNAL SD card of the Captivate, which won't be tough to figure out if you don't have an SD card in the phone.
3) EDIT--There is an easier way to get to recovery, but do this step anyway. Turn the phone off, then hold power, volume up and volume down. If you still want the android SDK (which will be very useful throughout your rooted experiences) follow the old procedure:
This step requires the Android SDK, and Android Debugging enabled. You can get the SDK here: Android SDK. Just download the zip, extract it to something like C:\Android. You won't need the Java dev pack or anything.
You can enable Android Debugging like this: From the homescreen, press Menu, then click Settings. Navigate to Applications>Development and check USB Debugging. Now, hook the phone to the computer. Next,
On a PC, click start>run>"cmd" (in the text box) or on a Mac, spotlight "Terminal". Linux users, you know what to do.
The command you will use is in the tools folder of wherever you extracted it to (IE: C:\android\tools), so be sure your working directory of command prompt is in that tools location!
adb reboot recovery
5) Give yourself a pat on the back. You are now rooted. You should see a Superuser application now.
