Hi, Today I change the region of my European 3DS to US region using CTRTransfer, but my question is: Can I remove the CFW after did the region change? or I aways have to keep the CFW to have the region change? If I did this, I'll Brick my 3ds?
Why remove CFW?Hi, Today I change the region of my European 3DS to US region using CTRTransfer, but my question is: Can I remove the CFW after did the region change? or I aways have to keep the CFW to have the region change? If I did this, I'll Brick my 3ds?
To be honest, I have no idea if the tickets and signatures are still valid and the CFW is patching the checks. If they are valid, then there won't be any problem. If they aren't valid, you will brick.Hi, Today I change the region of my European 3DS to US region using CTRTransfer, but my question is: Can I remove the CFW after did the region change? or I aways have to keep the CFW to have the region change?

Thanks for trying that. I would not have dared to do this. Another thing learned… Hopefully your test machine was not a very valuable one – for the case NTRboot would not have done the trick. It is not really good to lose a working device just out of curiosity.For science, I backed up my SysNAND and ntrboot flashed my R4i 3DS Gold RTS flashcart on standby.
CTRTransfer my USA n3DSXL with 11.8.0-41 firmware using 11.5.0-38J_ctrtransfer_n3ds.bin. I made sure to delete my SecureInfo_C and edit my actual SecureInfo_B at offset 0x100 from 01 to 00, aka USA → JPN.
Then, I went to HOME Menu to check that my 3DS is in Japanese.
Lastly, I Uninstall CFW.
I took out my flashcart, removed the SD card, and removed + reinserted the battery for good measures.
My shit bricked black.
lol. Well, I do hope to recover with ntrboot. If not, get ready to press F.
Edit - Yay! Lucky me, NTRboot saved the day. My baby is up and running again. So there you have it folks: you can't region change, uninstall the CFW, and expect it to keep working. XD
We've been through so much. I think I spent more time on it in GodMode9 and doing stupid stuff than playing video games. Oh well... To learn what happens, see the edited spoilers.'Thanks for trying that. I would not have dared to do this.

All depends: where did you get your SecureInfo_A of different region?
If you made it, it's unsigned... if it came from a console of the desired region, it's signed
(And of course you would need signed system titles, but I hope you got them from 3DNUS anyway)
You will need a SecureInfo_...B from a real Japanese console, of courseFor shits and giggles, I'll repeat this region change + uninstall CFW experiment again using sysUpdater and the JPN n3DS Firmware package found at that darth site:
Oh, and as you already were partially explained in that topic, it's because there are no Chinese or Taiwanese N3DSes (not that smart people bought the O3DSes when importing Japanese ones resulted in generally better product*) - the NS driver has hardcoded region-to-titleID mappings for Home and friends, and I have absolutely no idea of what it ends up doing on "nonexisting" regions (and of course, whatever you may manage to force it to run may not support C/T anyway; maybe you can jerry rig something with TestMenu and DevMenu... on CFW only of course!)previous attempt at making a theoretical n3DS TWN or CHN CTRTranger image:

There is the safety test of running the native firm from the uninstall 3s guide. If that test fails to boot to homemenu in any way it means you will not be uninstalling cfw unless you want a 3ds that wont work until ntrboot is used woth a flashcart to install cfw again.So if I backup my secure info_A (in my case) then restore it after I flash the ctrtransfer image to my 3ds I should be able to Uninstall cfw?
