No.

The full name of b9s is boot9strap. It is the latest way to wipe out the autonomous system of 3ds. It is equivalent to the upgraded version of the previous a9lh. By loading the bottomexploit key of the bottom hardware startup chip of 3ds, b9 can digitally sign any firmware and install it on 3ds. No system upgrade can eliminate b9, which is also the final completion of 3ds.

The perfect ending for Plutoo Symmetry 3ds, one of the developers of A9LH. A9 obtains control of 3ds by modifying the boot priority. B9, on the other hand, directly signs the cfw and writes it directly onto the system chip, allowing the system to regard the cfw as a legitimate program and gain control. For example: A9 is equivalent to renting a house, and b9 is equivalent to buying a house.
