Correct Title (mods pls fix): deja vu is dead (on new units)
welp
EDIT: technical explanation
EDIT2: oh boy
EDIT3: only vaguely relevant but sleepmode on downgraded switches is enabled in fusee master
EXPLANATION:
Deja Vu was an exploit that enabled full code execution on 4.1.0, including on post-July Switches, and was expected to work on Mariko (the Switch hardware revision). Details were intentionally scarce. A relative newcomer committed to Hekate a commit that would "optimize dram configs." Research showed that this commit was the backbone for the downgraded sleepmode in Hekate 4.6. It was quickly discovered that Deja Vu relied on a (still-unpatched) bootrom exploit, and that exploit was in the DRAM configs. Now that it is public, Deja Vu can be fixed in the same way Fusee Gelee was.
