I noticed there is a lot of people posting the same "odd" results I got and nobody having any clue what is up, and After experiencing TWO incomplete downgrades on my N3DS XL on 9.9.0-26U, there is quite a few signs as to how you can tell if you did get a partial downgrade, and which is why you may have some issues you can't find much details on or how to fix. If you find any other telling signs, you can post them here. An incomplete downgrade will show signs of being an 9.2.0 downgrade in the system menu, but these results below are signs of being an incomplete downgrade. Even if you did everything right, it can still do an incomplete downgrade. I had the correct updates file as once I updated to 10.3, I was able to downgrade within a minute correctly to 9.2 The solution to all these is to simply recovery mode, or update to 10.3 and then run the downgrade again. A partial downgrade is most likely highly risky to continue running on, and won't work as expected. 1. When you're installing CFW, PastaCFW + Minipasta run a blackscreen and freeze, or they kick you back to HBL. When you try to run FBI to confirm if it worked, it will still say invalid signature on CIAs. This is a sign of an incomplete downgrade as the signature patch cannot be done. 2. Your browser version is the same as your old FW you were on, and in some cases makes the browser inaccessible to the following error: "The Internet Browser is not usuable at this time." Which would mean the auto page for browserhax won't work, but with some fooling around I did find a way around this, but you're better off just updating to 10.3 and repeating the downgrade process because it will give you the issue from #1 3. CFW like Rxtools.3dsx + ReiNand.3dsx + Gateway Tools and such will immediately kick you back to HBL, without even giving an error like "No Emunand present!" 4. When you run Sysupdater to redo it, it will do the downgrade process, but only install 20 or less files before saying "NATIVE FARM: Installed." Also a sign of another incomplete downgrade. When you run it again it can also say it's installing, but not install anything and complete. 5. If the first time you run Sysupdater and it only installs a couple files and does "NDS needs to be powered off" error, this also means you've got an incomplete downgrade. 6. Being able to run Ironfall Invasion, aka Ironhax on 9.2 after a downgrade is also a sign of an incomplete downgrade, as it will never go past the 3DS w/ Nintendo logo on 9.2 due to Ironfall being incompatible with 9.2 (Correct me if i'm wrong, but this is what people have been saying) You can also use this to check: https://github.com/ihaveamac/downgrade-check/releases Thanks @ihaveamac This is the most telling signs I noticed, and seems to be an issue people are popping up with. Once again if you find more telling obvious problems to this issue, post here.
