My friend 3DS is on 11.3 without A9LH.

Her console stuck on disabling Child Online Privacy Protection in Parental Control Setting, like this.

Clear Parental Control Settings is not help. That option still enable.
When she contuine with second option ("Restart Confirmation").
She entered her birthday, Signature, e-mail.
And she got this:

Because she can't speak English well, Is there a way to fix this without calling Nintendo?
Is System Format work? I have OOT3D cart so I think I can run arm11 homebrew.
Thank you Very Much.

 

Is this work on this case?
Since she can remember her pin But can't disable that option only, even by removing Parental Control.

 

she said that the console was on 11.3. there is currently no way to put A9LH on a 3ds running 11.3

 

have you tried booting into recovery mode? hold A+R+L+Up(DPad) on boot. also, you should use soundhax for homebrew

 

You should try to remove the parental code, then doing it again. Just to see if that fixes it... Idk I haven't had this problem before, so I can't help much. Sorry! ;-;

 

I've seen a few reports of people saying that a format was enough to fix it when entering a birthday of an age over 13. Though, I've also seen people say you CAN'T format while the lock is in place (what would be the point if the kid could just reset the system to bypass the restriction?) So that's really up to you. As far as the signature thing goes, if you can't authenticate it to get them to send you the e-mail with the unlock code, then your only recourse is to open a ticket with Nintendo online. You can use the online chat function after opening a ticket to talk to someone and they will help provide a code to unlock your console if your information matches.

You can also just call, the numbers are toll free. I'm sure TWN can just call NOJ and have it fixed. Best of luck to you!

This one is actually for your region BUT I can't read it and google translate sucks but it's the correct page,

Those were just the closest I could find without being able to read it Lol. And yeah, I totally mixed myself up there haha my bad but they didn't have an option for Thailand so I chose the next best thing I thought haha.

 

Well that's stupid. I'm sorry Nintendo shafted you guys like that! So I guess yeah just deal with NOJ or other Lol.

 

I would too lol. I'm really surprised you guys don't have any official support, that's crazy. Then again I guess Ninty really only cares about NA, EUR and not even the entire Asian continent, nope just Japan. Lol
