Hacking Fully Uninstall without any trace A9LH

[cataklix]

Hello,

I'm going to send back to Amazon my N3DS XL for try to get one with IPS screens and because the price is going down with the switch release..

Can you tell me step-by-step how to completely uninstall A9LH without let any mark for returning it to Amazon

Thanks

Best option would be to restore pre-A9LH sysNAND backup.

Just this ? And it will completely remove A9LH and retake the 3DS on 11.0 like when I take it out of the box ?
Did I do that with de Decrypt9 option SysNAND restore ( not the one with "keep A9LH" ) ?

It will restore to whatever firmware you made the backup on. So if you made it on 11.0 then yes you'll be on 11.0
Yes it will remove a9lh
Use the one without keep a9lh

Okay It's a lot simple than installing it ^^
I hope I will get a black model with IPS screens...
