black screen after payload injected

[mandvbswitch]

Using incognito RCM on Switch Sysnand 8.1.0 + Emummc on partition 8.1.0|A 0.9.3

TegraRCM working well : green mark when RCM detected, orange symbol while injected, green mark at the end

Get black screen without info, no Incognito screen on my switch.
Revert to boot on ofw after long press on POWER.
