Ok, I'm doing slowhax for downgrading my 3DS to 10.4
On Plailect's guide he says:
I have DSiWare installed, should I format? I don't want to format :\ But I don't want to softbrick my console too :\
On Plailect's guide he says:
All variations of sysUpdater, not just sysDowngrader, have a very small chance of causing a “soft brick” once the downgrade is complete and the device reboots. This will cause the system to boot directly to the Nintendo error screen instructing users to power off the device.
The reason for this is unknown, but can be prevented by performing a system format before downgrading. It seems to happen very often on systems with ambassador status or who have DSiWare installed.
Once this error happens, it can only be fixed by using recovery mode (boot holding A + R + L + Up on the D-Pad) to update to the latest system version.
As of the time this is written, the latest version (11.2.0) has completely blocked all software downgrading, and if someone encounters this error they will be locked out of any further downgrading unless they downgrade their NFIRM.
