OK, so between everyone I know, we have these 3DS setups:
n3DS XL: 9.0.0-20U sysNAND, 4GB SDHC (never hacked)
n3DS XL: 9.9.0-26U sysNAND, 4GB SDHC (never hacked)
o3DS XL: 6.0.0-11U sysNAND, 4GB SDHC (never hacked)
o3DS XL: 4.3.0-10U sysNAND, 9.2.0-20U emuNAND, 16GB SDHC (Gateway only)
o3DS XL: 4.5.0-10U sysNAND, 9.4.0-21U emuNAND, 4GB SDHC (Gateway only)
o3DS XL: 9.2.0-20U sysNAND, 4GB SDHC (never hacked)
o3DS: 9.2.0-20U sysNAND, 2GB SDHC (never hacked)
o3DS: 3.0.0-6U sysNAND, 2GB SDHC (never hacked)
o3DS: 7.1.0-15U sysNAND, 2GB SDHC (never hacked)
o3DS: 9.2.0-20U sysNAND, 2GB SDHC (never hacked)
o3DS: 4.5.0-9U sysNAND, 2GB SDHC (never hacked)
o3DS: 4.5.0-10U sysNAND, 2GB SDHC (never hacked)
Is the 9.9.0-26U n3DS XL the only one we need to get downgraded to 9.2 ASAP?
What should be done with the 3.0, 6.0, 7.1, and 9.0 systems? 4.3, 4.5, and 9.2 are fine as-is, right?
I'm looking into downgrading my 9.9 n3DS XL now. Got the 9.2 firmware .cia file, and sysupdater -- any way to tell which version sysupdater is?
Thanks for any advice.
