Updating Deepthroat Simulator: Quest Edition without auto-update, and without losing your custom characters

Why nothing updates it for you

A game from the Meta store updates itself overnight. A sideloaded APK has no store behind it, so it stays at the version you installed until you replace it. Squircle Games said as much on the game's VRPorn.com page: there is no auto-update system, and each new version has to be downloaded again.

Update, 30 October 2026: the Premium listing now reads 1.66, and the developer's change list for it includes a fix for Quest 3 passthrough (our news piece on 1.66). The paragraphs below describe the gap as it stood until 29 October; the backup steps still apply to every update.

That would be a small chore if the Premium copy kept pace. It has not. Premium is still on 1.623. The developer's itch.io page dates that release to 15 March 2025 and has since published 1.63 in June 2025, 1.64 in August 2025 and 1.65 on 8 October 2026. A Premium member installing today gets a build more than a year and a half old.

Four releases Premium has missed

From the release notes we could read, the versions after 1.623 are more than cosmetic. Version 1.63 added interactions, fixed scenes that started with characters wrongly undressed and added Chinese. The developer posted the 1.64 notes in a comment on VRPorn.com: fixed pose positioning, a switch to disable world movement, a detachable VR interface and UI scaling. The 1.65 notes, which we could read on 24 October, are short: a settings panel that would not close is fixed, and character selection loads models from a source the developer calls SecretWaifu (our news piece has the details).

One fix matters more than the rest for Quest 3 owners. Around March 2026 the developer acknowledged that passthrough was missing on the Quest 3 and promised a version fixing it very soon. That promise came after the last Premium build, so the Premium copy does not have it. Neither the 1.64 nor the 1.65 changelog mentions passthrough, so there is no sign yet that the fix shipped.

Why VRPorn.com is behind

The comments tell an awkward story. Last year the developer wrote that it had not been able to reach anyone at VRPorn.com and wanted the newest version released. VRPorn.com's staff account answered that the team knew about the update and was waiting for migration issues on its side to be resolved before launching it. Nothing on the page since shows that happening.

Updating without losing your characters

The part of this game people invest in is the custom characters: VRoid .VRM models you copy onto the headset. They live in the app's own folder, which the developer gives as Android/data/com.SquircleGames.DeepthroatSimulator/files/VRM. That location is the risk.

Two Android rules decide what happens when you update. The Android documentation on app signing says the system installs an update only when the new version is signed with the same certificate as the installed one. And the documentation on app-specific storage says those files are removed when the app is uninstalled. The Quest runs Android apps, installed the same way Meta's developer documentation describes, so both rules apply here. That last step is our reasoning rather than a statement from Meta or the developer.

Put together: installing a new APK over the old one keeps your characters, provided Android accepts it as an update. If it refuses, uninstalling is the way through, and uninstalling takes the VRM folder with it. Hence the backup in the steps above.

The open question is whether the VRPorn.com build and the itch.io build are signed alike. Neither the developer nor VRPorn.com says. If you switch sources, from the Premium 1.623 to a 1.65 bought on itch.io, expect the possibility of a refused install and back up first.

Other reports on the page

Two Quest 3 owners wrote that the game did not work, one describing an APK that installed and then showed nothing when opened. The developer replied that it should work and asked them to join its Discord, and a later commenter reported the invite as invalid. A Quest 2 owner found it too laggy this summer. A commenter on the developer's 1.63 page said SideQuest refused the install over a virus warning. That is a single, unverified report, but it is another reason to take the file only from the developer's or VRPorn.com's own page.

A good game, badly delivered

The game deserves better distribution than it has. A developer that answers its players and keeps shipping updates is paired with a Premium listing stuck on a March 2025 build and a public exchange about not being able to reach the site. VRPorn.com should either publish 1.65 or mark 1.623 on the page as an old build that lacks the passthrough fix. Squircle Games, for its part, could say publicly whether its two builds share a signature, so people know before they lose their characters.

Until then, Premium gets you a working, older Quest Edition at no extra cost. If you mainly want current features, the itch.io version is the only route to 1.65 that we can document; do not count on it for the passthrough fix yet. Your own VRoid models are free to add; the developer's extra characters are a different matter, a Patreon benefit rather than part of Premium, as our page on the PC version explains. First time sideloading anything? Meta's developer-mode requirements are set out step by step in our EdenXverse fix.

What changed (30 Oct 2026): Premium listing moved to 1.66; quick answer, first step and FAQ updated, update note added above the version history.

What changed (24 Oct 2026): added the 1.65 changelog, which we could not read before, and corrected the passthrough outlook: neither 1.64 nor 1.65 lists the fix.
