Are you using Heimdall or Heimdall One-Click?

Franzferdinan51 · Mar 31, 2012

Uninstall kies and uninstall the existing usb drivers b4 installing heimdall ones.

Make sure you don't have any Samsung drivers installed. Restart the process, but try a different USB port on the PC & see if that helps. Rebooting may help as well.

Rebooting is always a good idea when you have problems. If you are following my guide read the notes about USB ports. Pick one for Heimdall One-Click and don't use it for anything else regarding your phone.

Keep trying.

Well done good job

lumin30 · Mar 31, 2012

And no you aren't "borked." People have this problem randomly and the reasons/fixes are also random. Without sitting in front of your computer myself it is hard to diagnose the problem.

ahhh ic okay that makes me feel better

atleast im not entirely ****ed thanks for the advice and ill do what i can im going to keep this thread open and going so that any ideas someone may have can pass my way

Thoroughly uninstalling all drivers, deleting One-Click, running CC Cleaner, and rebooting is a good place to start. Make sure Kies isn't installed. Make sure Samsung drivers isn't installed. You have to uninstall Samsung drivers in 'Uninstall Programs' to get rid of those. I use USBDeview to double check all the drivers for a port I want to use are deleted.

Next it is often USB cord related. Make sure it is not a loooong USB cable. Make sure it is firmly pushed in to the computer and phone. One person had to have his USB connection to the phone more to one side than the other to make it work.

Just keep at it.

And consider hitting thanks with the people trying to help you.

Get rid of all the old drivers!

Spot on advice to get rid of Kies and any other Samsung drivers. I've been working on this on and off for days, and finally got there through this last post.

One final thing - I used the Heimdall drivers to overwrite that ones that Windows had put in by default, that was the final touch that got it all working.
