[How-To] Samsung Captivate Root Froyo, Install ClockworkMod and flash a custom ROM

[ls377]

Does it matter that when I plug my phone in to usb i get an error on my cpu stating there is an error installing my device to cpu?

Yes. Did you install the correct drivers?

 

[JunGaList4323]

should I go to samsungs website to install the driver?

 

[ls377]

Yeah. I should have had them in one of the posts, not sure why I forgot them

 

[JunGaList4323]

alright, device driver is installed. I went back to the beginning with the one click app, and I am still seeing the same message, "waiting for device..."

 

[JunGaList4323]

I figured it out, thanks for the help

I worked through the root and installed Clockworkmod and downloaded a couple of ROMS from your list, however, whenever I install a ROM and reboot, The ROM gets stuck on the first splash loading screen and never moves. I have tried this on three different ROMS and have had no luck.

Please note that when a new kernel is flashed, and when you do a ROM you almost always have a kernel included, it will need to rebuild the dalvik cache on boot. This can take 5-10 minutes the first time only. If you gave it longer than that, I would boot back into Recovery mode and apply the same ROM again.

When you go into Recovery mode to install from a zip file, is it green or blue?

EDIT- Also, which ROMs are you trying? If you are trying to do the new Gingerbread ones, there are additional steps that may not be covered in this topic.

I was trying to install three different mods from ls377's list. Trident, Platypus, and Javelin. I let it sit for about 25 minutes and it never went past the first splash screen. I have to reflash from odin and then root again and reinstall clockwork and then try again but each time I have the same result. Also, my build number is 1011. I can root just fine and am able to install non market apps but the stock ROM is terrible.

Those 3 ONLY work with CM7 or MIUI. If you're trying other ROMS, use one of the non-CM kernels.

Yes, as noted above, those kernels are not for Samsung ROMs, only for CM7 based stuff. The stuck at the screen thing is a clear kernel issue, and easy to fix with flashing the right one. No muss no fuss.

What ROM are you running? 2.2 or 2.3?

I figured that out about CM7. I am now running fire fly without a problem. Thanks for the write up!!

I was experiencing the "unable to verify signature: failed" as well. I used SuperOneClick to not only root the device but it also had a one click option to enable the unknown sources option. Everything worked great.

Trying install clockworkmod............I select reinstall package (in blue texts) and get and I quote
Install from sdcard
finding update package
opening update package

I think the file at the download site is corrupted, since we had the same issue with someone else. I'll upload another one and post it, and let you know when I do.

EDIT: Try the link now, let me know if it works.

clockworkmmod wont read the roms installes on my sdcard.

I see the directory sd/ ,but it will not let me go farther.

[INFO]Download SuperOneClick v1.7 Credit goes to CLShortFuse for this great program.

Unzip the .zip file, and open the SuperOneClick program.

Plug in your phone (with USB debugging enabled). Click "Root"

Click Yes/OK on all the windows that pop up.

If the test passes, you're now rooted![/INFO]

Running stock Froyo (build FROYO.UCKB1, kernel 2.6.32.9) on Captivate.

Tried to root using SuperOneClick (tried once each using each exploit). In each case, SuperOneClick reported success, but my applications that need root cannot achieve root access. When they try, unlike my experience using rooted Eclair, the there is no popup from the SU application requesting root permission. The request apparently just times out and the application is unable to secure root access.

Any idea what I might be doing wrong?

Thanks!

Turns out the phone needs to be rebooted after rooting. SuperOneClick does not tell you this but I found the tip someplace and everything works now.

Thanks, I added that into the directions.

Hey folks. First, thank you for all the tips/tricks you provide. I've successfully rooted my Captivate and enabled sideloading with instructions I've found here. Initially, that's all I wanted, but now I'm interested in CyanogenMod.
I've searched and read numerous posts, and maybe I'm just confusing myself with all the information I've found, but I have a question you may be able to help with.
If I want to flash CyanogenMod, do I HAVE to ODIN back to Eclair first? My Captivate came stock with Eclair, and was upgraded to Froyo via Keis. Also, the ODIN instructions have a reference to the build number in the back of the phone. My build number is 1101, and the reference only discusses build numbers starting with 10.
I have also read a lot about overclocking and saving battery life. Can you provide insight on how I can accomplish this? My understanding is that some ROMs have this built in, but does CyanogenMod?
Thank you in advance!
