Hacking Help: O3DS is not turning on

[Hintens]

Hi guys, can someone help me?

My o3ds has arm9 + luma, and it's CFW is updated to 11.2. Everything was working fine until today.

Now, it wont turn on! When i press the power button, the screen remains black for 5 seconds, then it makes a noise and it turns off automaticaly. Does anyone knows whats going on? I've already checked my SD card and all files seems to be fine; Should i format it?

What kind of sound?

My guess is that a ribbon cable is loose pr damaged. Try to open the 3DS just slightly and then turn it on.

The same sound a sound box does when it turns on

I see. Try turning the console on while the upperscreen is folded in a 45 degree angle

I tryed it but it did not work.

I was reading the troubleshooting guide from plailect and tryed to do this with the o3ds fully oppened and it worked:

"
Try this test payload .

1. Rename /arm9loaderhax.bin, if it exists, to something else.
2. Place the arm9loaderhax.bin from the archive linked above in your SD root.
3. Insert your SD card into your 3DS and power on.
4. Press (A). Your 3DS should power off; this means arm9loaderhax is working and something else is broken; your device is not bricked."

But im still getting a black screen

I just replaced the arm9 file with a new one, now the system is TURNING ON directly onto LUMA

Edit: i wonder what happened, is my SD card defective?
