  1. Good day! This is my first visit to your blog! We are a team of volunteers and
    starting a new initiative in a community
    in the same niche. Your blog provided us useful information to work on. You have done a wonderful job!

  2. I have Samsung USB drive installed, but when I put my phone into custom ROM download mode (power + volume down + home+), my Windows PC says the USB device is not recognized. Though the USB mass storage tool works perfectly fine. What is the problem?

  3. Everything works for me!
    I had problems with usb drivers (KIES wont recognize my phone on two PC’s) but ODIN worked like a charm.
    Phone has fallen in a bootloop but clearing cache has solved everything!

    • What version of Windows do you use?
      I have tested ODIN with XP, 7 and 8 and works fine.
      There might also be an issue with your PC. The quickest solution would be to use a different PC.
