Hacking How do I remove Gateway's A9LH?

[loneZ]

After finish installing it I found out about Plailect's guide for A9LH and the benifits of that . So How do I go about removing Gateway's A9LH? I have no idea if I still have a sysNAND backup (I should have one called NAND.bin). I also can't access Gateway's menu at all even if I hold L on boot or remove my red card.

I never use GW so I can't be much of a help right now.
How Gateway's A9LH install on your system? Some kind of guide link you're using?

I used the guide that was on their site. http://scmods.com/gw_guide/GWFB-1.0.pdf

Restore your pre fastboot nand backup.

I'm not very good with my 3ds, so how do I go about to do that? I can't access the Gateway menu at all.

Edit : I'm dumb, didn't read the update where you had to press L + Select to get into the menu. Then I went ahead to downgrade using my sysNAND backup. Thanks
