Use SAFEMODE. Press L+R+A+DPAD-UP+POWER to boot into SAFEMODE and update your 3ds

In case you're paranoid, you can download md5sum.exe or winmd5free (for Windows) and run it against your files. You should get the following for N3DS/O3DS (USA). sysUpdater.zip is the latest julian20 build. The numbers below should match your files.

> md5sum.exe sysUpdater.zip "thefilefromthatsite-N3DS.zip" (USA)

009a955ed9216128c67ecfd2965971a0 *sysUpdater.zip
e5f40c3b155cfd12ef38be35d2e81d2e *thefilefromthatsite-N3DS.zip

Or if you're Old3DS (USA):

Dunno, it seems to...

Perhaps I'll give it a shot when my 3DS reboots from its recovery. I'll report back with my success or failure. Hopefully the former. lol
This spoiler is like Schrodinger's Cat. It could either show failure, or success, or both simultaneously in some sort of quantum superposition.

Can somebody please tell me if after I downgrade, would I lose all my apps and eshop account?
I ask this because when I downgraded my old 3ds 2 years ago (9.2 to 4.2) I lost all my files.

I figured out why the ZIP hashes weren't matching. I'm still gonna wait until I don't have to reformat, though.
