Well, firstly get a new battery. I'll check Amazon first.
But, they already have full cfw since they can get arm errors. removing it will just be more redundant than anything.
none of what i'm seeing on amazon is specified as official, and i've seen third party batteries warned against. i know i've had awful experience with third party vita chargers
Ah. Yeah, I don't think there's any real way to get an "official" KTR-003 (N3DS battery) without just buying a whole 'nother N3DS tbh. (Also, if you ever plan to upgrade to a N3DSXL, doing a system transfer with homebrew is a bit bullshit in my experience but still quite doable)
I know, I just still prefer to make sure everything is fully up-to-date and not some mish-mash of everything (which my Switch homebrew setup almost was)
That ones sold out. Altho I would strongly suggest they check to see if its a KTR-003 or a SPR-003 battery that they have in the console.
This is almost NEVER the solution. The "removal guide" even says that explicitly!
Also the newest versions of Luma apparently do that automatically.
Cfw uninstall is generally not recommended mainly because if there's some software issues in the system, like system file corruption, when you uninstall cfw you have no other way to fix your system, other than getting a ntrboot to restore some homebrew functionality, which defeats the purpose of doing the cfw uninstall in the first place.
There's a difference between making the homebrew apps etc. Up to date and installing cfw completely from the system.. And it's not a "mish-mash" of anything, if the system has cfw, it's easy to get back the homebrew apps in the case the sd card was lost (as in OP's case). He should just follow the guide here and he will have everything up and running in no time.
