Unable to factory reset switch

[acheronfail]

Hey there! I've searched around and can't find any threads where someone's had this issue, but apologise if one exists and I missed it...

Background info

• I have an original Nintendo Switch (I can use the jig to boot into hekate, etc).
• The only thing I did with hekate was install Android onto the SD card, I've not done any CFW in the Switch's operating system itself, etc.
• This switch isn't banned or anything - I can download games from the eshop no problem.
• In 2020 I did a full backup of the emmc/boot0/boot1/etc (it was on version 10.0.4) before I ever did anything with hekate
  • I'm not sure if I should restore to this, wouldn't it not work since I've updated the switch firmware over the years? I thought there was something with efuses and such, etc

The problem

But, lately, I've noticed that the switch has been bugging out a little (sometimes downloaded games break and I have to re-download, etc) and been having some issues here and there.

I want to perform a factory reset, but if I perform a factory reset (either via the settings menu in OFW or via Nintendo's maintenance mode) it just hangs with:

Restoring factory settings...
Do not touch the POWER button.

I've left it for over an hour sitting there spinning, and nothing happens.
If I hold the power button down and hard-reset it, it just boots normally into OFW like nothing happened.

Anyone know why factory resets might not be working? Is there any other way I can perform one?
