I'm gonna wait for ktm

yes

But the installer is already working properly ? it's just that the 3DSX is packed with everything

And that's the problem...
We were looking at ways to NOT have that and rather load them from the sd card instead. (i forget why right now...)

please do, it is way to dangerous to attempt a9lh without a KTM backup

Legal to distribute

Legal to distribute

Mainly, I guess... But I could also use it to modify/update the NAND payload.

That's the one.
Doesn't really help though when you have to compile it yourself anyway (or get someone else to).

I heard that some guy on GBAtemp with a Sylveon profile pic had an almost-ready to compile fork of arm9loaderhax... And that you just had to replace the OTP and run make...

Yeah i saw his fork I don't need it, i just build it myself.

 

[laramie]

I just throw a new otp into mine and type make and it all works perfectly... Haha

I can't build it even on Windows, sooooo... (I can't build the 3DSX)
I guess that if you're running on ARM9 you need fatfs lib to read files?

Spoiler: Wait, NVM. Only instructions to downgrade.

1. Did a new, fresh 9.2 emuNAND
2. Unlinked it using TinyFormat
3. Downgraded it using sysUpdater CIA
4. Dumped emuNAND, generated 0x4 and 0x5 CTRNAND xorpads
   
5. Decrypted the CTRNAND from emuNAND using the 0x5 CTRNAND xorpad
6. Encrypted the decrypted CTRNAND using the 0x4 CTRNAND xorpad, and reinjected it into the emuNAND dump
7. Replaced the NCSD header from my emuNAND dump with an O3DS NCSD header
8. Flashed it into my sysNAND
9. Removed the SD card
10. Pressed the power button

I used the Decrypt9 payload for the Spider 2.1 RSA_VERIFY exploit. Then, I flashed my 9.2 sysNAND backup.

Sorry but where can I find the payload? Is it in the latest release Decrypt9WIP-20160217-221257.zip?

https://gbatemp.net/threads/otp-guide.415140/page-19#post-6084203 Rename Decrypt9.bin to arm9.bin. Use the same link that you used to dump OTP from Spider to run it.

 

[Audioboxer]

So I done a lot more reading of this topic which I should probably have done before going head first off a cliff to get my OTP!

Basically I now understand I'm just going to have to be patient and wait for a payload that can boot directly into sysnand.

But hey thanks to the guys in the beginning who got all of this working.

Thanks! Will try later.

rename it to arm11 or arm9?

 

[Mrrraou]

ARM9. There is already an arm11.bin file given with this.

Just got my a9f.bin from my N3DS XL.
Thanks to everyone involved!
