I have an old 3DS which was on 4.X. I was following this guide https://github.com/Plailect/Guide/wiki/9.2.0-Update-(rxTools-MSET) And during the final step, the installation of the update the 3DS went black screen and I've listened a small click. I've waited more or less 5 minutes and since nothing was happening. Switched it off holding the power button. Now, when I try to power it up, all I get is a blue light and black screen. Is this a brick? Was the update still installing during the black screen period?
