moking1987 commented 8 years ago

sorry for the lack of information, this last monday I'm follow your guide step by step, part 1(nn3ds with 11.0 firmware, downgraded with FieldRunners method) and part 2 done successfully but when I restore my Sysnand Backup(9.2) the instruction in the section IV step 10 its update to the last version(11.0, 11.1 now.), I tried like a hour but update process always fail and my friend(the nn3ds owner) decided to "force" the update with the backup that we made with field runners, that was a big mistake and we brick(black screen) the nn3ds, we tried every troubleshoting method but all failed and the console didn't reponse :/, thanks in advance for any idea!

Do you have A9LH already installed? If yes, can you boot any payloads?

moking1987 commented 8 years ago

In theory I have it, but I only triedto load Hourglass but didn't work, do you recommend try with another payload?

rsubtil commented 8 years ago

Try booting Decrypt9

jaxrogers2 commented 8 years ago

It sounds like he reflashed his 11.0 NFIRM backup to his sysNAND or used dgtool while having A9LH installed

That's a hard brick right there either way.

rsubtil commented 8 years ago

I agree @jaxrogers2. Personally, @moking1987, you shouldn't have tried anything which the guide doesn't say.

Try booting w/o the SD card.

Plailect commented 8 years ago

Running dgTool while on a9lh = guaranteed brick.

Congrats, you wrote garbage to your firm0.
