Hacking Can't boot homebrew launcher from sysnand 2.1

[Cornejo]

Please I need help, I have been following the guide, downgraded to 2.1 successfully.
now I can't boot into Homebrew launcher, or I can't figure out how.
I have an o3ds. Any help would be appreciated.

2.1 doesn't support HBL.

EDIT: Or, more accurately, the HBL doesn't support 2.1. Whatever.

You run the exploit to get your otp.bin, then you restore your NAND Backup back to 9.2
or if you don't have a NAND backup from 9.2, you can uninstall a9hl, then update to 4.1 ~ 9.2 using a game cartridge, then you install a9lh again [SAVE YOUR OTP.BIN IN A SAFE PLACE]

BTW, next time you can post here: https://gbatemp.net/threads/3ds-noob-paradise-ask-questions-here.359035/page-1172

DaFUQ? NO do not listen to this wild crazy shit OP. Tephi I mean this with no disrespect but you should stop giving people advice on this stuff you really have a poor understanding of current methods.

Using the guide you shouldn't be trying to boot HBL. The guide very clearly states to launch safea9lhinstaller from the browser using a special URL, and then from there you restore a NAND backup of before downgrading (guide says to use emuNAND_original.bin) using an arm9 payload like Hourglass9.

So, I'm stuck as all hell, I swear I downgraded the rednand to 2.1, it seems like I did it to the Sysnand possibly. Not sure, I'm stuck were it tells you to go back to Sysnand and start Hbl and go to otphelper.

Are you able to boot into sysNAND? If so you can check your version from the system settings.
If you didn't downgrade sysNAND, could you please tell what entry points you are trying to use, and what exactly happens and how it fails.

I boot up, check settings, I'm on 2.1. Looks like I downgraded the Sysnand. Is there an easy way to go back, I saved all the nand, and emunand backups. No hard mod though.

are you using a really old outdated guide or something?

Link the guide, tell me what part-section-step you are on

At this point if you can boot into sysNAND properly you can simply skip the rest of part 4 and continue to part 5 - arm9loaderhax.
The OTPHelper is meant to help you transfer a downgraded emuNAND/redNAND to your sysNAND. If you already have a successfully downgraded sysNAND you should be able to safely skip that and continue to part 5.

Plailect guide,

1. Reboot into SysNAND, then get into the Homebrew Launcher through the entrypoint of your choice
2. Open OTPHelper
3. Select "One Click Setup" and confirm (you do not need to do an extra backup if asked, but you should make sure that you have copied the backup you made earlier to your computer as you will need it later). This can take a while.
   (If this fails or gives you an error do NOT continue or you may BRICK; you should follow this troubleshooting guide)
4. Cross your fingers
5. Reboot

The issue is it seems you accidentally downgraded sysNAND. Just as a final check make sure you are booted into sysNAND and verify you are on 2.1. The upper part of the lower screen should look a bit different from the newer firmwares. If you did manage to downgrade sysNAND on accident, then you should be happy it successfully downgraded. As stated above, that section is only designed to move a successfully downgraded emuNAND to sysNAND. Because you already have a downgraded sysNAND you should be able to continue to part 5.

He did say he checked, so yeah you could be right. if he downgraded straight to 2.1 h must be on an old 3ds? else he would have bricked? Anyways extremely lucky it worked out ok for him!

Ok then

 

[Temptress Cerise]

Ok then

If OP is following the guide as it is written today, then your post is sort of wrong or at least referencing an older revision of the guide. The latest revision of Plailect's A9LH Guide, makes us install A9LH right from 2.1, via the browser. We don't even need to actually get our OTP.bin (We are still told to copy and keep it safe, which everyone should be doing). Your post implies we have to obtain our OTP.bin (which was true in a previous revision, as I remember that one well) - and continues to suggest we need to restore to a 9.2 backup (which was true in previous revisions, as we had to, and from there we used the OTP.bin to install A9LH). It is true we need to restore a backup, but the emunand_orginal.bin backup, should have been updated to the latest version, and using Hourglass9, we'll always keep a9llh, so flashing to a 9.2 backup is pretty unnecessary, and the emunand_original.bin should be the backup with people's original stuff as well as having been updated.

And while you sort of reference understanding that v2 A9LH can be uninstalled, you sort of just stop there, you don't mention how someone would uninstall it, if they've already installed v2 A9LH, and give pretty bad advice as to how to get to 9.2 properly.

So yeah, your advice is sort of eh and probably why EmperorOfCanada said what she said in regards to your post.

I give up, i said if he DOESN'T have a NAND backup he should uninstall a9lh, upgrade with a cartridge and install a9lh back
I was reading the guide right now and i can't see where i said something wrong, i just said it with another words, that's all
I guess it's whatever i'm done
