Hi guys, I forgot to do a nand backup and downgrade my n3ds sysnand to 2.1. After getting otp I update my sysnand through system settings resulting in a hardbrick. I know this is user error. I have done many a9lh but this is the first time I forgot. Damned.

Anyway I have thought of a possible way to unbrick which I do not know if it will work.

1) Extract out unbricked 2.1 emunand in pc.
2) Hardmod and flash the unbricked 2.1 emunand to sysnand.
3) ???

Lets say the above method works is there anyway to update my sysnand back to 9.2 or 10.7? I am guessing recovery wont work. What about games with update in it?

Many thanks in advance!

UPDATE!!! (N3DS is unbricked!!!) *Stuck on 2.1 without any NAND Backups*

My situation:
I downgraded to 2.1 on a N3DS without any sysNAND or emuNAND backups totally. So I tried updating though system settings to 10.7 which causes a brick. (I did not know at that point of time).

So I extracted out the 2.1 from my microSD using 3DS Multi EmuNAND Creator and flashed it back to sysNAND with a hardmod.

After getting help from @d0k3 & @al3x_10m and many hours of trial and error I managed to update my N3DS from 2.1 without any nand backup.

So the steps are below, I have splitted it up into 4 sections.

Links to files needed
N3DS 10.7 firm0 and firm1 files
N3DS NCSD Header
Modded Decrypt9
OTPHelper-20160502-081624

1) Setting Up emuNAND
1) Use OTPHelper to dump your otp.bin and otp0x108.bin
2) Use OTPHelper to make a backup for 2.1 sysNAND and rename it to sysNAND 2.1 or something. (Incase the gamecart update fails, you still can use a hardmod to unbrick)
!!!IMPORTANT!!! - I bricked my N3DS a few times during updating to 4.5 using game cart. Steps 3 and 4 is like an insurance, no harm taking extra precaution
3) Turn off internet settings, format your N3DS, if it is in the format loop just wait around 2 mins or so and off it.
4) Boot into recovery by holding L + R + Up + A on boot, after that exit
5) Repeat steps 3 and 4 again
6) Update the N3DS to 4.5 using a gamecart
7) Create emuNAND FW 4.5 using gateway by use gateway entrypoint (go.gateway-3ds.com)
8) Use the modded Decrypt9, it is named as Launcher.dat *Start it using gateway entrypoint (go.gateway-3ds.com) (Slot0x05KeyY.bin needs to be in the root to use the modded Decrypt9)
9) Dump hs.app for emuNAND 4.5
10) Use Universal Inject Generator to create sysupdater.app(profi200's one,safesys and plaisys doesn't work)
11) Unmount SD and put 10.7 N3DS update pack in 'updates' folder, 10.7 firm0.bin and firm 1.bin and NCSD_header_n3ds.bin on root of SD Card
12) If you have a gateway card, replace the modded Decrypt9 launcher with gateway launcher
13) Put back your SD and inject sysupdater into h&s then reboot

2) Updating emuNAND to 10.7
*Make sure these 3 files are at the root of your SD Card*
10.7 firm0.bin
10.7 firm 1.bin
NCSD_header_n3ds.bin

1) I used gateway to enter emuNAND for 4.5 since I got a gateway card. If you have no gateway you can try other CFW? If anyone tested it can let me know, I will add it to this guide and put your name in credits
2) Open sysupdater in emuNAND 4.5 and press (A) to update emuNAND to 10.7
3) After updating it will auto reboot, take out the SD card and replace the Launcher.dat with the one from OTPHelper-20160502-081624
4) Launch OTPHelper in sysNAND 4.5 *Start it using gateway entrypoint (go.gateway-3ds.com)
5) Inject the 10.7 firm0.bin and firm1.bin into emuNAND 10.7
6) Use the Unbrick FW 9.x EmuNAND function (This will take quite some time)
7) After it is done go to NAND Backup & Restore and select Clone EmuNAND to SysNAND
8) Make a NAND backup of your 10.7 sysNAND and rename it sysNAND 10.7 or something (This is needed for A9LH installation)
9) Reboot and your N3DS is now UNBRICKED!!!

3) Downgrade sysNAND to 9.2
*Remember to delete the 10.7 updates folder from root of your SD Card*

1st we need to downgrade to 9.2, you can use Plailect's downgrading guide to downgrade
I used cubic ninja as the entry point for 10.7 to boot into homebrew launcher

When you boot into 9.2 it will show "An error has occured." message, don't worry this is normal.
For some reason it will crash around 3-4 seconds when you boot your N3DS because of the homemenu being loaded I think?

4) Installing A9LH (LumA Version)
We need to install menuhax so just grab the files from here, you should know how to use it by now.

1) Do the Preparatory Work from Plailect's Guide
2) Now we got a 3-4 seconds window before the N3DS will crash when we boot it
3) After you on the N3DS quickly tap the top left corner of your touchscreen to go into HOME Menu Settings
4) Tap Change Theme (This is needed to install menuhax)
5) After exiting it will crash again don't worry
6) After you on your N3DS again, quickly tap on the internet browser icon
7) Go to http://yls8.mtheall.com/3dsbrowserhax_auto.php to launch homebrew launcher
8) Install menuhax, configure it to type 2 (Auto Boot)
9) Exit menuhax manager and launch miniPasta, it will auto reboot into homebrew launcher again
10) Launch Safe A9LH Installer and press Select *Redo steps 9-10 if it hangs*
11) Power on your N3DS, it will auto reboot into homebrew launcher again, now uninstall menuhax
12) A9LH is installed in your N3DS but the error will still show up when it is on 9.2 so now we gonna update it to 10.7 while keeping the A9LH
13) If you have followed the Preparatory Work from Plailect Guide, you will be able to launch Decrypt 9 by holding Start button on boot
14) Launch Decrypt9, go to SysNAND Options > SysNAND Backup/Restore... > NAND Restore (keep a9lh) > Select the sysNAND 10.7 backup you made earlier on
15) After restoring you will have a A9LH 10.7 sysNAND
16) Use Decrypt 9 to inject fbi to the h&s
17) Now make a NAND dump of the 10.7 A9LH sysNAND


Pros:
N3DS is unbricked!

Cons:
You can't use any app or stuffs related to DSIware
BigBlueMenu is not working, but there are other .cia installers to replace that.
I can't format my N3DS too but hey its unbricked, who cares

No, that won't work. N3DS below 9.0 is a special case.


Yup, no reason why that should not work. Also, you are at a point where you have to experiment. You can even try all of Al3x_10m's steps on EmuNAND and see if that helps.

Because for sysNAND we need rxTools developer mode in order not to brick even on a normal working 3ds, but for emuNAND we can just use .cia version of profi2000 sysupdater. Which is why I think it might not work with emuNAND, but it should since its from the same N3DS.

 

[slslasher]

Ok I managed to unbricked my 3ds and install a9lh on a 10.7. But dsware is not working which isnt a big deal. Thanks to @d0k3 & @al3x_10m who helped me making it possible and myself for countless hours of troubleshooting and trial and error.

I will post a guide later, because currently I am using a hardmod so I will try to post one without using a hardmod.

i'm stuck in new 3ds 2.1 without 9.2 sysnand backup

if i have only a 10.7 emunand_formatted.bin backup, can i modiffy like a 10.7 sysnan? and restore in sysnand using decrypt 9 (arm11 entry point)

i want to skip the hard mode :v

You can just use otphelper or decrypt 9 from 2.1 and restore sysNAND using the 10.7 emuNAND backup. Don't need to go through what ever I did.

Anyway I have updated the 1st post with the guide.

[einhuman197]

ok I actually manage to flash back 2.1 emunand backup to sysnand which is working. Read from another thread that plailect is currently working on a solution for people like me who are stucked at n3ds 2.1 without a nand backup.

Shall wait for the good news.

And now you need a DS flashcard to install mset or alternatively use Gateway browser exploit. Now you have multiple options:
1) install a cubic ninja cia and install ninjhax 1,use that with sysUpdater and update .
2) use a cfw of your choice and install sysUpdater cia and use that to update
3)if you have a valid backup but a not- functional browser, use ninjhax 1 or mset and decrypt9 to restore your nand Backup. Please don't update to 6.0 because than you will get a brick because of the keys.

Boom now you have 9.2 and you can try it again.

if i restore that 10.7 emunand in my sysnad with otphelper o D9 i don get a brick? because thats my issue, i think in do that but i'm not sure about the brick

 

[slslasher]

I am quite sure it won't brick. Because I actually injected emuNAND into my sysNAND many times and it will work.

ok i will try with my o3ds xl (i have a lots of sysbackups) ,if works i going to use on the n3ds

it can be 4.x? or strictly 4.5? , can you compilate a modded decrypt for arm11.bin? (for those that have emunand backup and want only inyect de 10.7 firm 0,1 in emunand and want to use that in 2.1

6) Use the Unbrick FW 9.x EmuNAND function (This will take quite some time)
7) After it is done go to NAND Backup & Restore and select Clone EmuNAND to SysNAND

?

thanks in advance

Oh well... you need to do the legwork yourself, but the gist... [1] you need A9LH installed in your SysNAND, [2] Use that EmuNAND backup with Decrypt9WIPs NAND restore (keep A9LH) option. Everything will be fine then.

Can't he just restore the it with emuNAND 10.7 then downgrade it back to 9.2 again?

 

[d0k3]

Can't he just restore the it with emuNAND 10.7 then downgrade it back to 9.2 again?

Yup, that's another possibility. Without a hardmod, I can't tell which of the two is recommended more. I'd go the way I described, but the other one is valid, too.

i have't arm9 because i'm stuck in 2.1 without sysnand backup i only have a emunand bacukp, theres a way to get arm9 in 2.1? :v

If I were you I will use otphelper to restore sysNAND from the emuNAND 10.7 backup you got. But make sure the 10.7 backup is clean. Or you can use my method to get it to install A9LH in 9.2 then restore your 10.7 emuNAND backup keeping the A9LH. But you will need a gamecard that have 4.5 to update and a gateway card (you can try other cfw to see if it can boot into emuNAND 4.5 with it).

thanks bro, i have a gateway cart and maybe a sky3ds (my friend have one) , my last question is, if i use de otphelper in 2.1 the option clone emunand to sysnand, it can work? (final part in yout tuto (update to 10.7 unbrick))

Yeah it will work too. But your emuNAND partition in ur SD card need to be 10.7 and not the 2.1. If you made the backup you can inject the 10.7 using emuNAND tool or multi emunand creator.

thanks bro i will inject first the emunand 10.7 in emunand partition on the sd using the restore emunand in otp, later i'm going to clone emunand to sysnand, i hope that work, thanks bro or it will be nencesary restore de emunand with emunand tool?

since you have got the 10.7 emuNAND y would u wanna use the clone method anyway? Just restore sysNAND then select the 10.7 emuNAND. To be save dump your 2.1 sysNAND now if you havent done so.
