The problem with this frequent questions about uninstalling CFW is the unknown state of the consoles. This is gonna be long because it's not a direct reply but a general statement about this topic. Many (often new) members come here like this:
- “I hacked my 3DS a year earlier and have forgotten pretty much everything.” or
- “My friend hacked it for me…” or even worse
- I bought it hacked, that’s too complex; and I want it on stock firmware!”
Those people, sometimes without even basic knowledge about 3DS hacking, can’t answer the question: “
Are any system titles modified?” While – I have to admit – it is not very likely that an average user did such modifications on purpose,
we simply don’t know. Region changing (although mostly unnecessary) and CTRTransfer are not that uncommon.
I personally would have a really bad feeling giving the advise “Go ahead and uninstall!” In many cases it would probably go well,
but I don’t want to risk a single soft brick when keeping B9S has virtually no downsides.
In addition to that: Many non-members are visiting this forum. Just have a look on the
Online Statistics. It is also possible that random visitors wanting to get rid of CFW do not even know what exploit they are using and mixing up B9S with the older A9LH.
The warnings on the guide (and within GodMode9 when unlocking privileges for uninstalling B9S) aren’t there just for fun or to scare people for nothing.
Normally installing B9S, doing nothing to the system apps and uninstalling B9S later does
not brick the system. But, if you
@lukands , (or anybody else with the plan to uninstall CFW) have/has a slight doubt...
I advise against uninstalling except:
- you have a flashcart with ntrboot ready
- and tested you can successfully pull off the "trick"
So you can recover from the worst case scenario.
