Full Guide Release!

https://plailect.github.io/OTP/

All regions now supported!

If you appreciate this guide and the work I put into maintaining it, I accept donations through both Bitcoin and PayPal.

If you felt like the guide helped you out then I'd really appreciate it! If I get enough I may buy a 2DS for testing hardware stuff so I don't break another N3DS.

If the guide didn't help you out then I'm really sorry about that

 

[Plailect]

Right, but the only thing that happened in between section 1 and section 2 #14 was the use of tiny format. For those who already used tiny format i dont see a reason for the second back up, unless im missing something

If the downgrade fails and you have to restore a backup, you don't have to go through the tinyformat process + sysUpdater install again.

--------------------- MERGED ---------------------------

I hate to be that guy but its already up to page 106. On a N3DSXL so the only risky bit is flashing the Sysnand with the 2.1 build?
If it fails then I need to hardmod?

Side note I find emuNANDTool_1.0.1.exe and emuNANDTool_1.0.3.exe better for emunand dumping and restoring. Via pc its much faster.

Yes.

@Plailect, Thank you for your OTP Guide. By following your guide I was able to successfully dump OTP.bin from 2 N3DS and 1 O3DS. I should have thanked you much earlier but I got caught up in all the arm9loaderhax hype and dropped the ball. Keep up the great work.

You're welcome

Your emuNAND downgrade failed, restore emunand from the emunand_formatted.bin backup and try again.

What do you think about downgrading sysnand first to 4.5?

 

[Riku358]

What do you think about downgrading sysnand first to 4.5?

I have restored once again and downgrade again , but the same thing goes :c . Is it secure to downgrade to 4.5 first?

I have no idea, haha. I'm actually asking before I think about doing on mine

A friend of mine did the downgrade to 4.5 first and it worked.

So how are the success rates so far for N3DSXLs and 2.1? I thought I remember reading about some of those firmwares not having some support for newer devices and causing bricks.
These some kind of frankenfirmware combo?

yeah on n3ds you have to run a unbrick script wich will inject certain o3ds files to make a frankenfirmware so it would boot.

Ok kool, Ill just follow the tutorial. In the process of also building my new desktop so I'd rather not have to break out the soldering iron and do a hardmod too.

So what are some of perks of A9lh?
I'm currently using menuhax>ctrboot>rei. So this would replace the not 100% menuhax and allow a more successful straight boot to rei/emu?

 

[FenrirWolf]

Yup. a9lh makes it so that you are running cfw the instant you power on your console and you can boot directly to your emunand with 100% success rate.

mmm one thing Should I have to unlink my emunand and sysnand before doing the downgrade stuff? , that Native_Firm make me crazy xd

Thanks, half way through the old one .
So I'm in the process of matching up to where I was, which was right after the downgrade.
I typically prefer using the pc emunandtool to speed it up, but this definitely seems to cut back on the amount of backups.
Only thing worth noting is you seem mention delete the Updates folder and copy 2.1 updates in Section 1 and the same steps again in section 2.

Heh, whoops

 

[grandem]

There are so many tutorials for CFW so i am a bit confused.
But because you mentioned menuhax as outdated.
Is there any advantage with this guide?

Arm9loaderhax is the future and gives us everything, you'd be crazy not to use it

 

[DjoeN]

Quick question, for those that don't know (i know a little but not enough) what's the difference between:
- otp-0x108
- otp-0x100 (this one we need for arm9loaderhax)

 

[Dr Eggman]

Any ideas everyone? I'm having issues with the downgrade: keeps erroring out at 0004003000008F02.cia. I've formatted emunand, retried multiple times. I've used the same microSD to the exact same thing on another 3DS earlier, but doesn't seem to work.

0x108 includes the TWL ID, which isn't currently used for anything but may come in handy in the future so I have users dump it anyways.

Would it be worth downgrading again to grab?
