Hacking N3DS Won't boot, BlackScreen und Blue Light

[Chopsuey]

Hi,
I am pretty sure i am not the first one with this problem, i found several google entrys but nothing that really helps.

If i Turn on my N3DS, the Screens stays black, just the Blue light comes up.

I have Lume and A9LH ( Didn't turned my 3ds on for a while so i am not on Boot9strap)
I can open the Luma configuration, but what to do now ? ( Luma version 6.6)

 

[Kubas_inko]

First thing, update to B9S: https://3ds.guide/a9lh-to-b9s

 

[Chopsuey]

Ah okay, thanks, will this work even without the possebillity to boot up the 3ds ?
and will i lose my games/ homebrew and other stuff ?

yes. my friend had problems with his fw (was corrupted so he could boot at all) and it worked like a charm. You shouldn't lose anything (becuase we are not manipulating with FW)

 

[Chopsuey]

How will this fix my FW(?) brick if we dont touch the FW ?

(Had not the time to upgrade, will try this today but don't want to make it worse)

and, what size is the secret sector bin ? It just says >1kb, wich seems pretty small, is this correkt ?

 

[Chopsuey]

Okay, i just came to the Point :
Section IV - Updating the System


And at this Point i have no idea how to do this if i am not able to boot up my 3ds system.
So what to do now ? HELP !

You are getting way to far ahead of yourself. So you haven't ran SafeB9SInstaller and installed B9S, yet? Because you need to do that first and foremost.

exactly, yes. i did this, and it works.

 

[The Catboy]

exactly, yes. i did this, and it works.

Ok, I needed to make sure we were on the same page. So after all of that, you have Luma3DS setup and everything? Can you boot into GodMode9?

Of this all fails you may be able to recover with a ctrnand transfer using GM9

That's normal, B9S requires the SD card to boot properly. So that means you do have everything properly setup.
Black screen on SysNAND boot after Installing boot9strap

1. Ensure you have a working payload
   1. Check for the existence of boot.firm in the root of your SD card.
2. Try resetting Luma’s config and fix options
   1. Delete /luma/config.bin from your SD card
   2. Set your options when it boots
3. Test booting GodMode9
   1. On Luma3DS, hold (Start) on boot
4. Try deleting home menu’s extdata
   1. Clear Home Menu’s extdata by navigating to the following folder on your SD card: /Nintendo 3DS/(32 Character ID)/(32 Character ID)/extdata/00000000/
      • EUR Region: Delete 00000098
      • JPN Region: Delete 00000082
      • USA Region: Delete 0000008f
      • CHN Region: Delete 000000A1
      • KOR Region: Delete 000000A9
      • TWN Region: Delete 000000B1
5. Try booting without any cartridges inserted (including flashcarts)
6. If you previously downgraded with Gateway, ensure that you are using the latest Luma3DS version (v6.2.3 or higher)
7. If your NAND is of a version between 3.0.0 and 4.5.0, do the following:
   • Ensure that you are using the latest Luma3DS version (v6.6 or higher)
   • Download this file and rename it to native.firm
   • Download this file
   • Copy native.firm and cetk to the /luma/ folder on your SD card
   • If you have Luma3DS version 7.1 or lower, rename native.firm to firmware.bin
   • Delete both of these files after updating your device
8. Try following CTRTransfer
9. Ask for help at Nintendo Homebrew on Discord.

So these are your last options . If all else fails, you may need to do a CTRTransfer (which is linked in that post) which will remove your game as it will replace your CTRNand with the transferred CTRNand.
