For two of my Switches, I've decided to keep their official firmware as low as possible, just in case a coldboot exploit is discovered and applicable on either of those firmware versions. Other than that, you can set up emuNANDs on both Switches and use them for gaming, maybe update the one with higher firmware to the latest official one just so that you can play your legit games online.HEY GUYS!! havent been on gbatemp in maybe a decade or two ^_~
QUESTION: i have two launch-ish Switches and want to hack one for funsies. both are listed as SAFE by the switch serial number checker (https://damota.me/ssnc/checker)
is there any reason to use one over the other ?
XAW70000******(latest legit firmware v17.0 - i use for legit games/online)
vs
XAW4000*******(4.5 firmware - i got this on second hand on the cheap and never use it)
i plan on hacking the second one with the older firmware but before i do - anyone have any good reason i should use the other one?
the XAW7 has 4 repeating 0's then misc numbers and the XAW4 has 3 repeating 0's then misc numbers
is there any variance between them? or just different production batches.
edit: addeum:
the older switch is logged into a friend's old account. i plan to wipe it and maybe make a dummy account before hacking it?
As for the older Switch, you can probably wipe it, depending on what has been done to the Switch already. Do you have a clean NAND backup? Did you ever blank your prodinfo? Made its sysNAND dirty in any way by installing a pirated game to it, app forwarder, etc.?
If its sysNAND is cleaned and it's not banned, I'd link at least one account that you intend to use the most. Why? Some of the games require a linked NNID for some features to work, some won't even start without it. Sure, there's a linkalho app that allows you to link fake accounts and it should fix most of the issues for the games that require a linked NNID. I've run into one case where it didn't let me get in-game promotional items and it was with Animal Crossing New Horizons. You need a real account linked.
If you need some additional guidance, feel free to ask.
