    lol sorry I don't know if you good with english or not.
    then your best option for you is rxTools and luckily your on a good firmware and have the browser.
    http://www.rxtools.net/ just follow the instructions in the how to section by entering 4.5 as your firmware the instructions are very straight foward thought the touhgh part might be finding slot0x25KeyX.bin

    just use rxTools you don't need any type of flash card unless you want to play DS games

    also before doing all this backup your sd card and run the gateway 3ds launcher by visiting go.gateway-3ds.com while you have the launcher.dat on your sd card then click format emunand

    its actually cdn_firm.py which can be found in the tools folder you need to download and install python 2.7 to run it.

    running it will download the firmware.bin but also dont forget you need to find slot0x25KeyX.bin somewhere online.

    no just install python 2.7 to your pc and double click cdn_firm.py to download the firmware.bin (the old exe version was setting off peoples anti virus)

    I would remove the video from your post slot0x25KeyX.bin is super illegal and can get GBATEMP taken down with a DMCA notice.
