Can you solve this Rubik's cube from inside of it?

You have woken up to find yourself trapped in what appears to be a giant Rubik's cube. A Rubik's Cage I suppose. Bewildered, you take a look around (better video on imgur or just click the photo).

Each of the individual cube faces seems to have a letter transcribed onto it from outside, although it is difficult to read from inside.

Glancing down, you find a tablet and a diagram by your feet:

It would seem you need to enter a single 9 letter word into the tablet to escape. Who knows what will happen if you get it wrong... Maybe solving the cube will help reveal the answer?

Here's a better look at the sides of your cage (click for higher resolution):

Can you solve this Rubik's Cube from inside of it and find the 9 letter word to escape?

Don't get it wrong, there's only one attempt remaining!

• The GIF is sadly rather lower quality due to the 2 MiB cap on media here. Here is a better video on imgur of you looking around the cage. – Beastly Gerbil Jul 24 at 18:58
• Is the tablet looking for a single English word? – jpthesolver2 Jul 24 at 21:23
• @jpthesolver2 correct - one 9 letter word – Beastly Gerbil Jul 24 at 21:24

ROTATIONS.

First, solve the Rubik's Cube.

Every cubelet in a Rubik's cube contains a unique combination of either 2 or 3 different colored stickers. Because of this, for each cubelet, we can simply look for the correct spot on the diagram. Actually solving the cube is unnecessary (although for what it's worth, L F' R2 U2 F2 U' B2 R2 D L B' R2 U2 L2 B2 D F2 L2 R2 U F2 will solve it).

Here is the completed diagram:

Each face contains a message encoded with a Viginere cipher. The key for each cipher is the last 5 letters of the ciphertext of the previous face. The order of the faces is White, Red, Green, Blue, Yellow, Orange, hinted by the numbers on each face and the letters RGBYO on the white face.
Here are the faces and the messages they encode:

 White:  KEY1RGBYO
Red:    BKZ2PCCRT [RGBYO] -> KEY2ROLLS
Green:  ZGA3DHKGU [PCCRT] -> KEY3MOVES
Blue:   NLI4ZOUUC [DHKGU] -> KEY4TURNS
Yellow: JSS5MRHBM [ZOUUC] -> KEY5SPINS
Orange: DFABFUFUT [MRHBM] -> ROTATIONS


The last message in the chain is ROTATIONS, which is the password.

• i hate you, i just solved the cube after half an hour and saw your answer – RustEnigMachine Jul 25 at 6:08
• Correct! Congratulations and unlucky @enigmaticcard :P This was a slightly different puzzle, hopefully it was still enjoyable! – Beastly Gerbil Jul 25 at 9:50
