Check Fus Downloader ~ Download & Decrypt latest Samsung Firmware

37

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.

Besides official firmware, you can also find beta / test mode firmware with Check Fus Downloader. Beta / test mode firmware is a not yet (but soon to be) released firmware and is only intended to be used by advanced users. So you can try out the latest leaked test firmware before official release. By the way, you can also use the web version of Check Fus to find out latest firmware here.

      If not mistaken, Check Fus Downloader grabs firmware from Samsung server. So they are official except test mode firmware.

    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

    Thanks Jayce.

    • http://www.jayceooi.com Jayce

      No other download link. I got it from Check Fus Downloader website.

      Yes, there is chance of bricking even with Samsung Kies itself. :P

    • http://www.jayceooi.com Jayce Ooi

      Oh, it must be Sudden Death Syndrome. Well, we can’t do anything much on this. Just make sure that you are using latest firmware to avoid this issue.

  • Garydulfo

    • http://www.jayceooi.com Jayce Ooi

      Update or not is totally up to you. No need to update if nothing wrong.

  • Garydulfo

    Ok as of now 4.1.2 was my version,so i can your my s3 normally?or should i turn off it more often?

    • http://www.jayceooi.com Jayce Ooi

      “so i can your my s3 normally?” What do you mean?
      No need to turn off.

  • Garydulfo

    I was afraid that if ever i use occationally my s3 it may experience SDS,so i decided to turn off my s3 more often,
