Hacking Black screen with my R4i SDHC B9S

[WaiTiC]

Hello, can someone help me please ?
I followed a guide on 3ds.hack.guide (I can't put any link :c), I used the ntrboot method with a R4i-SDHC B9S, everything is ok, my 2DS (11.6) is now on a CFW

But I have one little problem, after this guide I wanted to remove ntrboot with "Section V - Removing ntrboot" for playing DS games on my 2DS

Now my R4 freeze my 2DS when I insert it (same when I tried with TWLoader), when I launch my 2DS with the R4 inserted, just a black screen and I need to force shutdown my console.

Maybe I'm just an idiot and R4i-SDHC B9S can't does anything except hacking 3DS

(sry for my bad english )

For this flashcard, you need to use the B9S Flasher from their official website. What have you used to "remove" the ntrboot?

It tells me "Flashcart : unkown" with B9S flasher

And the only thing I can do is
Poweroff
Reboot

Like I said I followed the "Section V - Removing ntrboot" of the website 3ds.hack.guide (I can't put any link/images, this is not helping..)

The guide told me to download a flashrom for my R4i SDHC B9S (they gave me a link)

And I followed this

Instructions

1. Power off your device
2. Insert your SD card into your computer
   • This is the SD card from your 3DS, not the SD card from your flashcart
3. Create a folder named ntrboot on the root of your SD card
4. Copy backup.bin from your flashrom backup .zip to the /ntrboot/folder on the root of your SD card
5. Create a folder named payloads in the luma folder on your SD card
6. Copy ntrboot_flasher.firm to the /luma/payloads/ folder on your SD card
7. Reinsert your SD card back into your device
8. Insert your ntrboot compatible DS / DSi flashcart into your device
9. Launch ntrboot_flasher by holding (Start) during boot
10. Read the red screen warning
11. Press (A) to continue
12. Select your flashcart
    • If you do not see your flashcart in the list at the top, read the bottom screen for more info on each option
13. Select “Restore Flash”
14. Press (A) to proceed
15. Wait until the process is completed
16. Press (A) to return to the main menu
17. Press (B) to power off your device

And it's not working.
(I swear to god if this guide bricked my R4, I'm gonna be so mad)
