Homebrew Back to my 3DS XL after a long time, how should I update?

[Loonatiks]

Hi!

A long time ago, 1~2 years ago, can't remember exactly, I follow some guides here and successfully hacked my N3DS XL.
But after playing a couple of games, I dropped it and never played anymore. Now I don't know how could a update it...

I would be happy if you guys could give a clue about how should I update it.

The things i have on my 3DS:
I have RX-E 10.7.0-32U
BlueMenu.cia
RX Tools

Thx
PS: Also, there is a way that I can un-hack my 3DS ?

1. Take out your SD card
2. Turn on your console
3. Put back your SD card when the home menu shows
4. Change your theme
5. Start from the beginning of https://3ds.guide
6. Follow the optional "Move emuNAND" section

Your 3DS probably has menuhax only, so it isn't really "hacked". After following steps 1-4 menuhax will be uninstalled and your system will be stock
