Old3DS bricked(?) after installation of arm9loaderhax

[ST1998]

After I installed successfully and without errors on arm9loaderhax, I turned off the console, extracted the SD card, put it on PC, and made some backups to put everything somewhere. After that, I put back the SD card on the Old 3DS, I tried to turn on it and it did not turn on anymore. I tried with various methods, even without the SD card but the console did not work.

First I was in the original version of 11.2.0.35E, then later in the modified version of 2.1.0.4E.
The otp.bin file does not think I have had any anomaly, since it was created after installing of a9hl.
I'll give you a little brush up your mind with the same guide that I followed, 3ds.guide/safectrtransfer-(homebrew-launcher).

Unfortunately I have tried for so many attempts, but the screen is always black.

And what should I do?

I made a small discussion about Discord and they told me that the only way to solve the problem is to do Hardmod.

ST1998, did you figure anything out, a hardmod is not too hard, although it does require some experience with a soldering iron
