Homebrew Black Screen After Downgrade 2.1.0

[mrfpsciro]

Please, read everything before posting.​

So i've started the 3DS hacking process and everything was running ok. (https://github.com/Plailect/Guide/wiki)
But, when I downgraded to 9.2.0, it ended with a black screen that resolved easily when I changed the theme.

After that, when I downgraded to 2.1.0, again, ended up in black screen. The guide told me to put the SD card after launching the sysNAND. It loaded. However, the problem wasn' t resolved, after all. It continued to stay with a black screen and only connected without the SD card. I ignored the fact and I installed the arm9loaderhax. It was installed with no errors. Then, when I rebooted it, again: black screen.

If I delete the Luma3DS options will enter in LUMA3DS screen, but when I boot the 3DS, it will stay in the Black Screen.

Oh, and now if I take off the SD card it won't boot anyway.

How to proceed? ​

Check your payloads.folder.

So payloads folder should be that one?

A Hourglasses Menu Appears than Restore Nand Backup on Sysnand Options

The directions tell you word for word on what you need to do.

 

[gnmmarechal]

Yeah, just go and restore the NAND backup you had with Hourglass9. You already have A9LH installed.

Now I understand that I should hold first select. That's working.

But what about the black screen with the downgrade? What should I do? Just restore a backup?

restore the emunand_original backup, and you should have a working 11.0 A9LH + Luma3DS SysNAND.
