Alright, so I had an OLD 3DS XL laying around that I didn't really played from a long time (busy days) and I decided to look into all the "Hacking 3DS" stuff. Yeah, I am a complete NOOB when it comes to this stuff. So first I did some research and found that the first thing to do is to install Homebrew launcher. I did that and it turned out fine. I could run the launcher from the 3DS sound app. The second thing to do was to install a CFW and I really made a mistake of not doing any research what-so-ever and just started following a Youtube video guide. Here's the link to the guide: As far as I know in the first part of the video, he downgrades the firmware to 2.1.0 or something. I originally had 11.2.0-35E. Yeah I had not updated in a long time as I didn't used it recently. The first part went really smooth, the 3ds was downgraded successfully and I could see the "Ver 2.1.0" in settings. So the next part is some browser exploit. I did that exactly as he did with downloading all the same files and placing them exactly like he does but when I typed the link "http://rxsaa.3ds something :/" my lower screen went blank and upper screen froze, basically the 3DS froze. So I turned it off and turned it back on only to see some wierd options like SysNAND and stuff. I guess it was asking me for "booting options" or something, I have a slight Idea that it might be due to "LUMA" or not, Idk :/. So there were a list of different options to select from, the first one was something about "SysNAND". Being the idiot that I am, I thought that selecting nothing and then pressing start would boot the device normally, lol. I did that and everything went blank. Now when I turn On the 3DS with the SD card both screens turn on but remain blank. The 3DS doesn't even turns on without the SD card, the blue light flashes on and then off and that's it (without the SD card). I can't even boot into safe mode because it gives error that safe mode is not available in Ver 1.x/2.x I know, I should have done some research :/ Finally, if anyone can come up with a solution, please go easy on me as I am a complete noob. Thank you all.
