I recently got my switch modded (Picofly), I was able to use it normally for a few days until one day it got super slow and restarting it would brick it (stuck on the nintendo logo) could still access hekate ,and it was overheating like crazy, even though it wasn't being used, I needed to replace all the files for me to open it, I researched for days but every "FIX" I found wasn't working until I tried turning on airplane mode for the sake of it and everything worked fine like it was brand new, I can use it now but without using the internet. I want to know what could have been the cause of that issue, is it hardware problems or software problems?
