League client not loading properly.

UPDATE 8:

So the patch just wasn't released yet for NA despite the installers trying to install patch 9.5? I uninstalled again and asked around a few friends, who told me the patch was going live about an hour or so ago, I finished (re)installing League OCE game files and then rebooted the client and switched to NA region again.

Suddenly, like magic, no crashes patching! The client even logged in and is right now installing Game files too! riot plz

Sorry for all this being a waste of time, I guess. I'm not entirely sure why the patch was staggered, but thousand yard opinion, maybe delay the NA installers release until the patch is live.

.. TL;DR at end of post

After moving around some files and going through Hard Drive maintenance, I tried reinstalling League. At first the Regional installers were running into errors every time around 99-100%, then they would restart the installer and after restarting, would bug-splat every time. So I tried the alternative installer zip, and that worked a lot better, downloading and running the client fine.

However, after each attempt to run the client, it would install the latest patch, then when the client started it would state that it needed to revert back to a previous patch and reinstall, then would patch again. The patch would complete and the client would start, except this time, when the EULA was displayed, it only showed a tiny window instead of the full client. This window is the only interact-able section of the client, ie there is no invisible accept or decline button hidden, clicking around the visible client window only clicks away from the client to whatever is behind it.

I am posting here before raising a support ticket because I have already exhausted majority of the support articles and I'm kind of hoping someone here has an experience based solution.

TL;DR

1. Can't reinstall league
2. alternative installer zip works, but doesn't load client properly
3. Hextech Repair tool didn't help either

.. UPDATE 1:

From a thousand yard view, It appears the installer / repair was searching for a League install location, similar to hextech repair tool, instead of using / assuming the locating it was running from was the correct one. This is important because I found out there was several old directories still listed in REGEDIT that I have since removed, and after removing them, attempted another install. The NA regional installer failed again, but the OCE installer worked?

I'm still a little clueless this doesn't seem to line up that much with the information I have found out, but none the less everything seems to be working and the client is no longer repeating patch cycles or displaying incorrectly.

.. UPDATE 2:

After the OCE regional installer worked, I switched regions back to NA using the client login interface. The client patched again, the same 1.52GB, before giving the same error as before. (Unknown issue while patching, client needs to restart) This time the client actually started instead of showing bugsplat, but the client still wants to roll back to a previous update.

The client automatically restarted and began a 101MB patch, but will give the same error while patching here too. The error will occur at 24MB every time, rather than near completion.

At this point I'm in an endless patch rollback loop, "There was a problem patching League of Legends. We'll restore a backup version and try updating again after you restart the patcher" Every time.

.. UPDATE 3:

Patcher passed 24MB several times in a row now, crashing repeatedly at 74.xMB out of 101.9MB.

.. UPDATE 4:

Found an old reddit post detailing how to add "--disable-patching" to the desktop shortcut, this is temporarily allowing me to log into League without any errors. I am right now logged into NA with no patch loop running CLIENT VERSION: V9.5-12916268.12915950

.. UPDATE 5:

After asking a favor from a friend, they screenshot their version number so I could compare. Their version number is V9.4-12926417.12926273

They are not required or receiving any update or patch notifications.

.. UPDATE 6:

After testing a custom match, there are no League game files. League never loads and all I see is the client showing "reconnect".

The client still runs an endless patch loop when not using "--disable-patching", but ONLY FOR NA REGION. I am now switching regions to find out if this is replicable with any other region.

.. UPDATE 7:

NA still the only client not downloading properly. Hextech repair tool fails to 'clean uninstall', task log shows 'Downloading installer... Failed' Hextech repair tool fails to re install the client even after switching regions in the hextech repair tool. (I'm not sure if the region picker in HexRepairTool is purely for checking service status or if it affects the installer region)
