Check Fus Downloader ~ Download & Decrypt latest Samsung Firmware

Checking new official firmware upgrade while using custom firmware on your Samsung phone or tablet is not an easy task. Because Samsung Kies and built-in software update will not notify you when there is a new firmware released. So you have to check on news website or blog for the latest firmware info. Or you can use Check Fus Downloader to find it out by yourself. In addition, you can also download the official firmware and install it with Odin manually. This is available on Android and Bada platform.

  3. Hi Jayce,

    Do we need to save this exe file in a certain directory? I’m getting “Error while reading file. Try delete dbdata.db and restart the program.” error. I already tried to delete the dbdata.db and try to move it to other directory but no to avail. Can you post a link of your file maybe the site is broken due to number of people who try to check JB..:D

    Also any chance or % of bricking the device with this process? I’m kinda hesitant especially now that I got defected installer. :p
