Wall jump off of the Upper-Left Namihe and then Spring Ball jump up and out of the Lava. Pausing early in order to get more horizontal distance by equiping Spring Ball may help.

Entrance condition:

"comeInWithGMode": {
  "mode": "any",
  "morphed": false
}

Requires:

{"notable": "HiJump"},
"Gravity",
"canSpringwall",
"HiJump",
"canUseEnemies",
{"lavaFrames": 390},
{"or": [
  {"and": [
    "canDash",
    {"disableEquipment": "SpeedBooster"}
  ]},
  {"lavaFrames": 150}
]},
"h_heatedGModeOpenDifferentDoor"

Dev note: This strat is not useful unless Samus has lava proof but not heat proof. Otherwise, the non-G-mode variant can be used. FIXME: These lava frames are lenient, they are what it would take without Gravity (the non-G-mode variant also doesnt account for Gravity).
