Hacking Question Switch does not boot past Nintendo logo

[Nagisa]

Hello,

I just received a switch which can't boot past the Nintendo logo in OFW and past the atmosphere logo when booting from CFW. It also shut downs and reboot after some times.
If I boot into OFW fast enough from hekate it shows the full battery logo then nothing(no Nintendo logo).
I tried to fix the battery sync but nothing changes.
Any advice on what the problem might be ?

You could try to boot into the recovery mode by pressing down vol up and down and then push the power on button.
There is an option to reset the Switch back into factory settings, cleaning everything out.

If that doesn't work, try dumping the NAND with Hekate and mount it with a PC.
Maybe your NAND is messed up.
NxNandManager can also check if your boot0 and boot1 partitions are valid, those also need to be the right version in order to boot.
You never know how the previous owner messed up this Switch.

You can try rebuilding the nand. Just google for a tutorial, theres plenty.
