Downgraded skyrim to 1.6.640 and now textures and meshes are ruined.

[Cat Bee]

I followed this guide to downgrade my skyrim to 1.6.640: https://www.reddit.com/r/skyrimmods/comments/18bh43k/if_you_accidentally_updated_your_skyrim_here_is/
Now that I've downdated it to that version, all of my textures and meshes are completely broken. Im playing with these mods and the appropriate SKSE version:
SSE Engine Fixes for 1.6.629 and Newer
8.4 A Quality world Map
All in one Address Library (AE)
Alternate Start - Live Another Life
Crash Logger SSE AE VR - PDB support - CrashLogger
DyanmicAnimationReplacerAE v.1.1.3 for Skyrim 16629
Faster HDT-SMP
FNIS SE 7.6
JContainers SE
MCM Helper SE (1.6.659)
Nemesis
Papyrus Extender
PapyrusUtil AE SE
RaceMenu AE 0.4.19.14
SkyUI 5.2
SSE Display Tweaks
True Directional Movement
UIExtensions v1-2-0
Unofficial Skyrim Special Edition Patch 4.2.9
XP32 Maximum Skeleton Special Extended.

Even after disabling all mods, the game still has super messed up textures and is unplayable. I start a new game and can't even see the player and the ground is super messed up. Is there something I did wrong? I also have screenshots: https://i.imgur.com/FF5jf5c.jpg

Edit: Ok, somehow it has fixed itself I guess. I reinstalled, launched 1170 once to see it work vanilla, downgraded to 640, making sure to delet the acf file and everything, launched it vanilla and it worked, and then re-enabled mods and it all works fine. I'm wondering if the mesh/texture problem came because I didn't do the acf file thing, or whether it was because I didn't launch it first or something and it didn't initialize, but either way it works now. Also guy who kept yammering about 640 and older versions not being supported, you were not helping and were quite annoying lol.

Unfortunately, anyone who downgrades is pretty much on their own, as only the current version (1.6.1170) is supported. The only people who should be on an older version are those who had an existing build and never updated, and it is up to them to troubleshoot any issues they may have. The only thing that can really be suggested is that you update to the current version of the game.

Sorry, but that's just the way it is.

yeaaa dont do that. Your talking like by downgrading that means no one can or will help him. Which isn't true and more and more people are downgrading.
This kind of talk isn't helpful at all and shouldn't be supported.

Now getting back to the issue at hand im not seeing anything that should mess with textures and such or at the least to that extent. I would say you messed up the downgrading proccess somewhere. Maybe a BSA file is missing.

I'm not a expert when it comes to downgrading using that method so im not entirely sure. If you feel comfortable enough could you post a screenshot of your data folder? Mainly the skyrim bsa files.

[Nabinkemper]

Might I suggest you perform a clean install and try it once again. Here is an excellent guide for setting up the best possible environment to run the game.
https://steamcommunity.com/sharedfiles/filedetails/?id=2743619856

After the install is complete, you can try the downgrade process again. Read through it carefully. All of the files in the app manifest downloads must overwrite the Skyrim SE files in the game folder. Don't forget to remove the BSA files mentioned at the end of the guide.

If the process doesn't work, then you can reinstall and keep the current version as SMR1957 suggested. Please keep in mind that downgrading or holding on to an outdated version of the game is playing with borrowed time. Everyone will need to upgrade eventually as the mod author's are not going to maintain older versions of their mods indefinitely.

Here's a guide on how to downgrade and lock it. The locking part is especially important.

VERY Important update On How To Revert Skyrim Update

Intended for those who accidentally updated their game.

Reverting to Skyrim Version 1.6.640 / Old CK versions.

Press Windows + R and type steam://open/console, this will open steam console, then you'll have to type in the following commands (proceed by typing one by one):

download_depot 489830 489831 3660787314279169352 <- Game Files Part 1
download_depot 489830 489832 2756691988703496654 <- Game Files Part 2
download_depot 489830 489833 5291801952219815735 <- Game Files Part 3 (SkyrimSE.exe)

download_depot 1946180 1946182 5099162879680505807 <- CreationKit.exe
download_depot 1946180 1946183 1633303557398589581 <- CreationKit Files

Note that the download time will vary per person, but once it's done, you'll have to locate your steam folder, generally at C:\ProgramFiles\Steam\Steamapps\Content, and inside there will be two folders, one will be named app_489830 and the other app_1946180.
The first one is your Skyrim game, the second one is the Creation Kit.

For the Game and the CK:
Now open your Skyrim installation folder and delete everything inside of it, and go to the app_489830 folder previously mentioned; there will be 3 folders inside (depot_489831, depot_489832, and depot_489833), and inside each folder there will be game files. Copy each of the contents to where your Skyrim folder is at (it should be empty before you do this).
Do the same with CK if you're interested in having it. Now go to C:\ProgramFiles\Steam\Steamapps\ and find the appmanifest_489830.acf file, right click on it and click on priorities and set it to read only.
Done.

For the CK ONLY: if you like me manage not to update your Game but forgot about the CK.
Open your Skyrim installation folder and go to the app_1946180 folder previously mentioned; there will be 2 folders inside (depot_1946182, depot_1946183). If you like me only need to revert to the old CK just copy what is in the depots folders to you Skyrim installation folder and press yes when prompted. Upon opening your CK you may or may not get a message saying the CK need to unpack the script files, answer Yes.
If it's not yet done go to C:\ProgramFiles\Steam\Steamapps\ and find the appmanifest_489830.acf file, right click on it and click on priorities and set it to read only.

You're now in 1.6.640 and the game will never update.

I tested this method with the CK and it's working like a charm

Enjoy your gaming time

Good day mate :lunar2019wavingpig::lunar2019coolpig:

Afterwards, check if all mods are for the 1.6.640 version.

[smr1957]

As for all those advocating downgrading, it is NOT recommended and no, a person will not receive help - at least not from the most experienced forum members who have literally thousands upon thousands of hours experience in both the game and in assisting in these forums over the course of many years (as can be seen by some of our post histories). As posted in the PINNED TOPIC Helpful Links and References, only the current game is supported, and anyone who is not on the current game is on their own. This is posted in the following section under What We Can Support:
https://steamcommunity.com/sharedfiles/filedetails/?id=2880736526
Those of us who constantly are active in the forum, and have been so for years, have seem far too many posts by people who followed advice from those less informed or knowledgeable to downgrade their game and had their game broken. If an individual wishes to downgrade, that is fine (it is, after all, your game to play or break as you wish) - but they should not be recommending others to do so, nor should anyone who does so expect assistance when the game breaks due to their following bad advice.

This is one of the reasons for this following guide (from the PINNED TOPIC Helpful Links and References as well), so that people can see who actually has experience and has proven reliable when giving advice in these forums:
https://steamcommunity.com/sharedfiles/filedetails/?id=2898569762

As said, people may do what they wish and listen to those they wish - but they should not be surprised when detrimental things happen to their game when they do things that are not recommended by experience forum regulars.

Here we go again with the "trusted regulars" tantrum.
Cringe.

I followed this tutorial except I can't find the folder with the appmanifest_489830.acf file. I launched the game again after following the tutorial and it is still the exact same. I'm really not sure what it could be.

[Alex]

Just start a search for the file.

Did you do a fresh reinstall?

[Wizard]

I'm not weighing in on the downgrading part except that it's not something I would do personally.

For the OP however, here's a quote from a poster in another thread regarding the app manifest, and where to find it:

"go into "C:\Program Files (x86)\Steam\steamapps" look for a file called "appmanifest_489830.acf". Right-click it and put a check-mark in the box that says "Read Only" then click OK.
That's it. Never will your game update again without your explicit consent.
Should you choose to update at a later stage, simply remove the Read Only option and it will update again."

I'm sorry but you are full of it. Best that you move on. You arent helping or contributing and are spreading misinformation.

No idea what you are talking about to be honest. I wasn't being edgy and nothing i said was edgy or meant to be taken as such. Everything i said was true. The modding community isn't hell bent on keeping skyrim up to date as that person says. Hence why most mods that are scripted have a SE and AE version. On top of that Downgrading is a normal thing now a days with all the pointless updates showing up.

Theres no "downgrade and your on your own mentality" in the community. The only major factor in this is Arthmoor who runs the unofficial patch. And that in its self doesn't mean anything as he has a history of being difficult and pretty horrible to others and there are links to archived versions.

So can we keep this thread on topic now?

[Alex]

But we are on topic. The old guard are simply saying that they don't want to help in this matter, since they disapprove of it. It's their right, they ain't the tech support who has to help, but they aren't your parents either. They can't forbid you to do it. You don't have to lash out with cringy stuff like "you're full of it", okay?

I merely copied the guide as is, since my approach is based on self-accountability. Just try it if you dare, if you can't/won't upgrade. Either it works, or it does not and you'll have to reinstall. Whichever happens, won't cause any major damage, but may provide some valuable troubleshooting experience.

P.S. I wouldn't have recommend that method if I didn't test it beforehand or if it could cause serious damage. I did guide a friend through the procedure and it did work.

[Mental Clarity]

How are you installing mods? Maybe update again, make sure textures are working and then go through the process again. I don't have experience as I simply stopped my game from upgrading. Seems like something got deleted during the process.
