Well, this is extremely frustrating.

I've downloaded Heimdall 1.4RC1 for my T999, and upon following instructions exactly down to the letter, I get met with "Claiming interface failed" when trying to flash CWM on my phone. I've asked just about everywhere and searched on Google, with every source telling me to unload drivers associated with Samsung Kies, which I have never installed. All I have is my mac (running OS X 10.8.2), so "finding someone with a windows computer" is not an option. Is anyone here using Heimdall 1.4RC1 on OS X and experienced this issue? I would love some help here, as I've been sitting here for hours trying to understand what is going on.

If anyone is having the same issue, I solved it, as the instructions on the CyanogenMod website makes no mention of installing the Heimdall kext for OS X. Upon loading the kext, I was able to access the device the next time I ran Heimdall. Cheers.

I'm just having the same problem. Where can I get the kext? The Heimdall zip for 1.4RC1 does not include it.

Thanks!

EDIT: OK, I got it from Heimdall's github page.

OK, so I installed the kext and loaded it and still getting the same Claiming interface failed error.

EDIT: OK, unloaded Kies kexts and now it worked, thanks.

Yeah, I want to see if I can edit the instructions on CyanogenMod, as they make no mention of loading Mac kext modules, which could cause a lot of problems.

I'm glad I was able to figure it out, because the internet is an impossible place to get help, especially when it involves macs. You wouldn't believe how many times I was told to give up and find someone with a windows machine.

I'd do it, but I rather solve the problem in my hands than to run off towards the perceived easier solution.

If you are still having trouble, try this on your mac´s terminal

it will kill kies.....

$ sudo kextunload -b com.devguru.driver.SamsungComposite
$ sudo kextunload -b com.devguru.driver.SamsungACMData
$ sudo kextunload -b com.devguru.driver.SamsungACMControl

$ sudo kextunload -b com.devguru.driver.SamsungACMControl

This only works, however, if you had kies installed in the first place. If you're flashing roms, the best thing to do would be to remove kies completely.
