Hi. I am suspecting about my corrupt bootloader on my r4. I had two r4i-sdhc, one of this unfortunately my console damaged it because the console shutted off while upgrading...(don't ask me further information xD) The other one well, it worked on my Dsi and a Ds lite but on the 3ds can't dump and/or run... So I am suspecting about my bootloader. Can I rewrite it? If yes, how?
