Tutorial  Updated

OTP Guide

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 :(

Ok, that's what I thought, and of couse I won't downgrade with the GW, I'll only use it to install FBI :)

e: just remember one question that I forgot to ask:
In the zip that @Plailect give, the 3ds and updates folder have capital letters "3DS" and "Updates", actually I have "3ds", and for the friend's 3ds that I have downgraded, I have make "updates" dir, not "Updates", that significant or not ?

Anyone can share their mind about that ?

To be fair, it's not over until you run A9LH and it doesn't break ;)

But yeah, you completed the OTP guide successfully! Stuff's nerve-wracking.

Is it normal for it to fail over 10 times on step 16/17 of https://github.com/Plailect/OTP/blob/master/Old_3DS_Spider.md?
I have an o3ds and I think it fails around the same CIA and the top screen goes black and the Nintendo error ('An error has occurred...') pops up on the bottom screen.

Edit: Looks like the guide has been updated to include updating emuNAND to 10.5. This made it work for me.

I don't see why a9lh installation would fail, tho.

No idea how, but it can.

Alright, it's past midnight, I've been at this all day, final results:

N3DS: Running A9LH. Swapped Sys- and EmuNAND successfully. Accidentally removed FBI (oops) but the power of having a recent backup let me get it back.

O3DS: Updating EmuNAND let SysUpdater run properly, got OTP, ran a newly compiled A9LH and...

Dammit.

Though I'll admit it's unlikely, it's still one more hurdle of clenching.

Obtained otp.bin on 2ds could only downgrade to 2.1 from a 10.5 emunand.

Starting to think that should be a step on the guide for old ones, seeing a lot of that as the solution around here (and can confirm it myself)
