  1. Thank you for a very informative post.

    The only problem I faced was to download the firmware from the site. Since it connects to and that site gives a pretty slow speed.

    However I was able to follow the steps and make it work

    Thanks once again :))
    Keep the good work !!
    God Bless

  2. Hi Dialandroid. First of all thanks for your effort making this video very clear and helpful. I'm following all the given steps to flash counter and it works! The issue I'm getting now is once after download from sammobile the stock firmware and flash it and I could see the software status its modified. Where I could see in your video it comes to Normal. My device is GT-i9300. And the firmware I've downloaded from sammobile version 4.1.2. Is it I should download 4.0.4? Need your advice thanks!
