It was Decrypt9...I'm pretty sure even emunand9 can't do it.
Not even Decrypt9 can back up nand on anything 9.3+It was Decrypt9...
Im tired....
Thats why I said that I may have already dowgraded 10.3 at that time (I cant remember well)Not even Decrypt9 can back up nand on anything 9.3+
In fact I am pretty sure Decrypt9 doesn't work on 9.3+
Can you set up menuhax and then use it to boot directly into sysupdater?Are there any alternatives to SafeSysUpdater and sysUpdater? I keep getting a black screen on my 2nd unit and I've been here for like 20 mins trying :/
They are searching for an alt TO SysUpdater. NOT an alt to get into it. And as far as I'm aware, you can use BBM, FBI, and the such. BUT, it poses (what, a 99% chance of brick? Not worthCan you set up menuhax and then use it to boot directly into sysupdater?

For downgrades you have the 2 or 3 sysupdater variants (including safesysupdater), and the very unstable mch2 port of FBI. BBM and the rest won't work for downgrades as they do not exist in .3dsx form and even if they did they would not support mch2, which is required for downgrades.

But I've been reading online that you can't use sysUpdater (OR SafesysUpdater) to downgrade N3DSXL. If I have a NAND backup of my N3DS XL(Hard mod) and try to run sysUpdater, I'm for sure able to flash the nand.bin back into the unit incase sysUpdater breaks my N3DS XL right? Just wondering
You forgot my confirmation.This is crossposted from reddit.
This is a summary / compilation of the information from this thread. Please don't follow any random instructions you find on that thread, there is quite a lot of misinformation going around. This is very much untested and a hardmod is necessary.
Do not ask if you can achieve this without a hardmod, you can't.
This is an apparently working implementation of the "FIRM partitions known-plaintext" exploit detailed here. Reports of successful downgrades are sparse or unconfirmed, but seeing as anyone who tries this has a hardmod and a NAND backup (hopefully multiple backups kept in multiple locations), there isn't really much that can go wrong.
This should work on both a New and Old 3DS.
Keep in mind throughout this that 10.4 and 10.5 use the same NATIVE_FIRM. Also keep in mind that 10.3 does not have a unique NATIVE_FIRM, and we will be using the 10.2 NATIVE_FIRM.

What you need:
- Your 10.4 or 10.5 NAND extracted using your hardmod
- Raugo's autofirm pack (Mirror)
- msvcr120d.dll (Mirror)
- The appropriate decrypted NATIVE_FIRM CIAs which can be found on my Github page.
Instructions
1. Extract the autofirm pack to a folder of your choice
2. Place a copy of your NAND file (named "nand.bin") in the autofirm folder
3. Download the appropriate decrypted 10.4/10.5 NATIVE_FIRM and the decrypted 10.2 NATIVE_FIRM as CIA files
4. Rename the 10.4/10.5 NATIVE_FIRM file to "firmoriginal.cia" then put it in the autofirm folder
5. Rename the 10.2 NATIVE_FIRM file to "firmnuevo.cia" then put it in the autofirm folder
6. Place the msvcr120d.dll file in the autofirm folder
7. Run "start.bat"
8. If everything worked, then you will have a modified "nand.bin" containing 10.2 NATIVE_FIRM on 10.4/10.5
9. Flash this "nand.bin"
10. Get access to the homebrew channel (Starter kit here) (Mirror)
11. Downgrade to 9.2 (Mirror)

The hardmod itself is pretty much unpatchable (unless they can implement some sort of password protection when writing the data back but that's probably impossible)is a hardmod for ever or can nin patch it?If not i may pay for some1 to do thos for me But id want it done clean looking that can be attached/detached easily i dont want wires always hanging.

Most modders like myself also give you options as to where you want the mod installed as well. Here are a few example of my work.is a hardmod for ever or can nin patch it?If not i may pay for some1 to do thos for me But id want it done clean looking that can be attached/detached easily i dont want wires always hanging.
