Nintendo Switch: Firmware 9.1.0 released and breaks Atmosphere & other CFWs – SciresM says changes are minor with Hexkyz already retrieving Master Key
With Christmas being just 20 days away and the Switch selling like hotcakes, Nintendo has just released a firmware update possibly to break CFW one last time before the year is out! In this article, we’ll be looking at the recently released Firmware 9.1.0 and what it means to CFW users.
Nintendo releases FW 9.1.0 for the Switch & Switch Lite
Nintendo has just released another update for the Switch but if you have a fusee-gelee vulnerable unit, you’ll probably be able to use CFW on it fairly soon!
Continuing their trend of semi-frequent updates, Nintendo has just released Firmware 9.1.0 coming a little over 2 months after FW 9.0.1’s release which was on the 30th of September. Similar to other non-x.0.0 updates, this update is pretty minor and according to its official changelog, it brings along:
- A fix to an issue in which the colour animation wasn’t displaying correctly when attaching a Joy-Con to the console
- Stability improvements as usual so that you’re ensured to have a rock-solid experience while playing on your Switch this Christmas season
By taking a look at a report, by yls8, containing the full change list, numerous sysmodules seem to have been updated but the change list is shorter than that of FW 9.0.0 and SciresM has stated that in FW 9.1.0 ‘little changed besides the usual’ at first glance.
Firmware 9.1.0 breaks CFWs but Hexkyz already retrieves master key
The Master Key for FW 9.1.0 has been public for hours so it doesn’t seem to have brought enormous changes to security!
According to reports online, FW 9.1.0 seems to break Atmosphere and other CFWs meaning that you should probably stay away from updating, especially on your SysNAND, for now if you care about hacking your console. However, it’s not all bad news since prominent Switch developers have already taken a look at it and shared some pretty good news!
As mentioned above, this firmware update is reported to have only done minor changes and as a result, Hexkyz has already dumped its master key meaning that Nintendo didn’t change much security-wise. Other than that, SciresM has already identified the differences between FW 9.0.0 and 9.1.0’s TrustZone while also sharing an IDC file containing labels for every function inside the TrustZone IDB.
Conclusion
With all the above in mind, it’s probably safe to say that Atmosphere and other CFWs, such as SX OS, will probably not take too long to receive an update allowing them to be used on FW 9.1.0. However, until then, it’s probably better to stick to your current firmware version and be very cautious if you have an ipatched console running hacks through FW 4.1.0!

I don’t understand why this is posted on every article? Is this like Youtube first comments? or am I just not in on a joke?
“She” ( the writer of this article ) used to be a “man” what you see in every post it’s a combo of both his/her nickname.
