UPDATE: 1/6/2016: Recent developments have resulted in a way to downgrade 10.3< systems. That being said, these exploits are experimental and errors made during the downgrade process may brick your system. For a guide on how to do this click here. You do this at your own risk!

The US Standard N3DS (non-XL) comes with a minimum firmware version of 9.5. If you are looking for an exploitable console stay away from these.

At this point most systems will have a firmware above 9.2. You should work off the assumption that any serial number not on this list will be above 9.2.


Note: If your N3DS is missing either the 3d demonstration video (paper airplane video) for US systems or the Tomodachi Life demo for EU systems, it has likely been updated, so please don't post that system.


Huge thanks to BobDoleOwndU for his continued maintenance of this list. I've been crazy busy this month and his continued updates ensure people can buy with confidence.

Hey folks, I've been compiling a list of reported version numbers and what firmware they are running. Don't be afraid to ask staff where you buy your N3DS XL for a specific version, it's odd but they will prolly help you out. If you have a N3DS XL (especially one on 9.4 please post below with the following info)


Version Number (up to the first 4 digits):
Region:
Firmware:
System Color (checking a hunch):
Note: confirmed means 2 or more temp members have confirmed the version and firmware, or it has been confirmed with images

US Firmwares by version number:

disclaimer: I am not responsible for anyone purchasing the N3DS XL based on this list and getting the wrong firmware version. This list is based on reports by the gbatemp community and its accuracy can not be ensured.
