[Captivate Q&A, Help & Troubleshooting] madetoservehim:
There have been those that run into problems after installing the XXJP3I9000 update on the Samsung Captivate and attempt to reboot into recovery mode. The issue that they have is that since the Captivate has no physical home button to select an option like you can with the Galaxy S, you can't select an option, and therefore you can't reboot your device regularly. While I am in this same problem and have not figured out a solution, I have started this thread to post what knowledge I have about this issue so that others may help get this issue figured out. If anyone has information on how to fix this problem, please comment below. Let's fix this!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First of all, the key combinations that standardly would work with the original captivate firmware will not work anymore. Pressing all three buttons (Vol+, Vol - and Power) will only power cycle the phone, that is, until you let up on the buttons. Pressing Vol+ and Vol- and then plugging your phone into the computer will also do nothing. (By nothing I mean will take you back to the recovery menu)

Every key combination will only take you back to the recovery menu, so key combinations seem to be out.

If you boot into recovery mode, take out the battery and put it back in, all the while keeping the phone plugged in to the computer, the phone will enter the "POWER RESET OR UNKNOWN UPLOAD MODE", which will show your device in windows as being a Samsung USB Composite Device and a Samsung Mobile Modem (gadget serial, Windows 7) While this may be helpful, you cannot run ODIN or ADB in this mode, nor does this allow disk access. If you have Samsung Kies installed, it will detect a device, but will never complete loading it.

Other information with this method: On the phone screen, as well as showing "POWER RESET OR UNKNOWN UPLOAD DEVICE" the screen will also show the following in red:

RST_STAT =0X1

PMIC_IRQ1 =0X0

PMIC_IRQ2 =0x0

PMIC_IRQ3 =0x4

PMIC_STATUS1 =0x40

PMIC_STATUS2 =0x2c

If this helps anybody, it was a pleasure

Another method I found briefly was that after installing Kies, and rebooting the phone into recovery mode (again) my computer detected four new devices, two of them being Samsung Android devices and one being a disk drive. Potentially, without freezing or error, the drivers that are included with the Kies software will detect and allow for disk management while the phone is in recovery mode. Three of the four devices installed without error for me, but the fourth, the actual Android device, continued to say "installing device" until I unplugged the phone out of frustration. It has since not detected those four devices again, and I have yet to figure out how to do that again. The nice thing about that was that although the adb.exe reboot download command did not work, adb.exe did detect the phone. if this is true then rebooting normally or into download mode should be easy.

The last thing I noticed is that button furthest to the left on the main screen on the captivate will close the recovery menu when pressed, and leave the background behind, and then will reopen the recovery menu when pressed again. This is showing me that the four touch buttons are operable, but not configured. If it were possible to reconfigure the actions that pressing these buttons do, then it would be easy to be able to reboot the device normally.

I have compiled information to the best of my ability, and here is a question to ask, that I think will help solve the problem. Can the captivate with I9000 2.2 software run adb in recovery mode?

Comments, Questions, and Most of all, answers would be appreciated for me, as well as for other users with the same problem as I. Hopefully, this thread can be the solving point for this problem.

Many Thanks,
