    Will this work for all samsung galaxy s3 models or only the quad-core version.

  • Pathedog

    My s3′s camera doesn’t work with this version of the kernel. But, despite this little inconvenience, I was able to reduce voltage up to 135mV without pb.

  • jacklimefrost

    any solution or perhaps a workaround regarding the camera issue?

  • Wins

    I followed the instruction above, but it didn’t work at all. After Odin rebooted the phone, it can’t boot up. It just shows the Samsung model and then goes blank.

    I came from Jelly Bean AOSP for Galaxy S3 build 3 by Faryaab
