So this has been eating me about Albion for decades - how the fuck do you get into some of the secret rooms in the Umajo dungeon!?

Namely:
(see first attachment)
The two bottom right rooms here.

And:
(2nd attachment)
The one on top (in the middle) and the one on the right (near bottom, has door but can't be opened).

Anyone ever got into those or are they just bugged?

Thanks!

The door can be opened only from inside, and to get there, you have to use the levers (each time one lever moves/opens door in the middle), when done right you can enter secret passage (is not really shown on map, as it is invisible "door" = wall. Just for one combination this wall goes incorporeal and you can just walk through it.)
On the map (first attachment) you can see that room south-east, with a monster inside, without doors.
Use the flares/lever right and bump into the walls (not the glass walls, it has to be real wall, well, it should look like stone wall anyway)
I got there eventually but I was already so confused by the triads of attempts, that I totally lost track of "what exactly was done before I could enter"
When already inside, kill the monster, check the treasure (I think that only one is really having a reward) and the "fall down". now you will be in the "locked" room of the second screenshot - the door will open for you just fine (it opens without problem from inside) and you are back in that dungeon.

Tried to reproduce it... no avail so far. My best guess is that it may be connected with the secret doors on the lower level with the sign "If you want go through the doors, you will go through the doors", but I remember that I entered the secret room on the higher level, so logically it still does not fit.

Want to bump this because I've been banging my head on the walls for hours (literally) and want to see if someone is around now four years since the last post who knows how to get in those rooms. There must be some way. I've tried every lever combination and there aren't many. Two of them will get stuck and permanently block access to most of the level, including the part with the secret room.

The only thing I didn't really try was the flames, but it would take forever to brute force solve it with having to run around the entire dungeon to rub your face on the walls for every combination. There would normally be a hint for that kind of puzzle but there is just nothing.

Up to this point in the game there were no obvious "secrets" (you can see the room through a transparent wall) that weren't easy enough to solve with a little searching. So wtf. Maybe it is bugged.

I cast raise dead upon this thread:

I've found two methods to gain access into that space, courtesy of
the-spoiler.com/RPG/Blue.byte/albion.5.html

On this level, go North through the door. The small room South-West has only
some Magicians to fight, so go East into the room with chests. Open the locked
North chest(42 Torch & 114 Rations) and the locked South chest(52 Rations).
Leave and go through the North-East door. In this large area, you should see
3 corridors with portcullis and coloured floor plates. Go South and you should
see a small room. Go to the back(West) and press an orange button. The
portcullis will rise. Go to the front and step on the floor plate. The doors of
the room will be raised and the fires will chase you. Run quickly to the first
corridor and run to the end, hiding behind the orange floor plate. As the fires
follow you and hit the floor plate, they will distinguish. After all fires
dissapear, you are safe to enter the small room and pull all the switches on
the walls. Repeat for the other rooms for the green and blue flames. Heres a
summary of what to do:
1.Go to the back of the room and press the orange button.
2.Step on the floor plate in front and run to the respective corridor.
3.As the 3 coloured flames follow you to the corridor and hit the floor plate
of the same colour, they will distinguish.
4.Finally, return to the now safe and open room and pull ALL 4 switches on
the wall.
If you did everything correctly(pulled all the switches), the door in the South
-East will open. Go through and into the gap in the North-East. Follow it to
the South to a floor plate in front of a portcullis. Stand on it for a while
and the portculis will raise. Search the most North-Western trash(Lugh's Hand
Helmet) and the most North-Eastern trash(Frostbringer). Now bactrack to the
room where you entered the gap on the North-East wall and go through the North
door. In this large area, there are many rooms with curtains. Monsters lurk
inside most but one contains treasure. The 3rd room from the left contains a
chest(6 Turquiose Healing Potion, 4 Blue Healing Potion, Poison Antidote,
Sickness Antidote, 3 Light Staff & Iskai Long-Sword). Now head through the
passage in the South-East. There will be fireballs shooting out. Try to avoid
the fireballs and quickly go West. You should then go to the stairs at the end
of the passage.

Alternatively you can activate cheat mode:

During the Game, go to the menu. Select options, and in the options-menu, just type "schnosm" on your keyboard (without the " ) and your screen will flash white one time, so you know it worked. Back in the game, the cheats are enabled.
About the Producer-Mode:
- A picture of the Producer is shown in the lower right.
- The Map is revealed, you can see persons and monsters on the map, and you can teleport everywhere by clicking on the map.
- You can Walk through walls
- You can reach everything whith the "use"-cursor
- You can End fights and still get XP (Command in Battle)
- Enemies can't engage you in battles
- All spells are maxed out and only cost 1SP
- You can deactivate this by using Alt + F12 again

I thoroughly investigated the rooms and couldn't find a way in. After looking up as much information on the dungeon as I could find I'd basically satisfied myself that they just aren't accessible in normal gameplay. I talked to the kind people over on the Albion Discord and they pretty much confirmed it - looked over the actual map data and couldn't find anything that would let a player into there.

I believe that there's another entirely separate room in that same dungeon (on map 246 west of the room with the three doors) which is also inaccessible, but it's a room with no windows or doors visible from the outside (maybe it was supposed to have been accessed by an illusionary wall?) so you wouldn't even know it existed in a normal playthrough.

I get the feeling that Umajo in general is one of the last areas in the game that was being worked on and that some parts of it are just tantalizingly unfinished.
