Wallpapers, Launch & App Audio
How to import .tendies PosterBoard packs, set reboot-free Lock Screen text, override App Launch Images, and replace notification tones in v1.1.1.
- .tendies & .zip Share import
- iOS 27.3 fix in v1.0.7+
- App Launch Image auto-backup
- v1.1.1 App Audio + LocalDevVPN

Importing Tendies Wallpaper Packs
GestaltX v1.0.6 added Wallpaper Settings for importing, applying, and cleaning up animated PosterBoard wallpapers, followed by v1.0.7 (Build 11130112) to fix container path discovery on iOS 27.3:
| GestaltX Module | Introduced | Accepted Input | Runtime Behavior |
|---|---|---|---|
| Wallpaper Settings | v1.0.6 (27.3 fix in v1.0.7) | .tendies & .zip via Share Extension | PosterBoard container on iOS/iPadOS 27.x |
| Lock Screen Text | v1.0.6+ | Custom string in System Settings | Applies immediately without device restart |
| App Launch Images | v1.0.6 (27.3 fix in v1.0.7) | Custom photo from library + full-res export | Automatic original snapshot backup & restore |
| App Audio Library | v1.1.1 (Build 11140102) | Custom notification sound files | Live cache refresh + Pairing / LocalDevVPN capture |
To import a wallpaper pack, select a .tendies or .zip file in Files, tap Share → GestaltX, and return to Wallpaper Settings. Keep two community findings in mind: first, single-descriptor PosterBoard packs import cleanly while multi-wallpaper bundle archives from standard Cowabunga collections may need unpacking into individual descriptors first (#143). Second, tapping delete inside GestaltX invokes deleteImportedWallpaper() on GestaltX's local store, whereas removing an active wallpaper from the iOS Lock Screen switcher is done by swiping up on the Lock Screen gallery itself (#126).
Custom Lock Screen Text
Inside System Settings, GestaltX includes a Custom Lock Screen Text control introduced in v1.0.6. Unlike MobileGestalt capability flags that require a full restart, custom Lock Screen footer text writes directly to the active configuration and appears without rebooting your iPhone or iPad.
Clearing the text field or restoring default settings removes the custom string cleanly without touching your MobileGestalt cache.
App Launch Image Overrides
App Launch Images (added in v1.0.6 and updated for iOS 27.3 container discovery in v1.0.7) customizes the cached splash snapshots iOS displays while apps cold-start:
- Automatic snapshot backups: Before replacing any app's launch image, GestaltX backs up the original rendered image so you can restore the stock splash screen in one tap.
- Full-resolution Photos export: You can save existing full-resolution launch assets directly to your Photos library to inspect exact pixel dimensions and safe-area aspect ratios before supplying a replacement image.
- Zero binary modification: Overrides happen inside the target app's mutable launch-snapshot cache directory rather than altering signed
.appMach-O or storyboard files.
If an app regenerates its launch cache after an App Store update, open GestaltX and re-apply your saved launch image preset.
App Audio Library & Capture Guide
Shipped in GestaltX v1.1.1 (Build 11140102), App Audio Library lets you replace per-app notification sounds with custom audio files on side-loaded builds:
- Select a listed app or capture paths: Open App Audio Library to browse detected apps. GestaltX caches the discovered app audio list and refreshes captured sounds immediately after scanning.
- Use Pairing + LocalDevVPN for unlisted apps: If a messaging or social app does not show its notification sound path automatically, open Pairing & Device Connection, ensure your
LocalDevVPNtunnel is connected, and trigger a notification while running the built-in capture guide. - Pick custom audio & apply: Choose your replacement sound file using the fixed
v1.1.1side-loaded audio picker. IfLocalDevVPNfails to connect, GestaltX halts capture immediately and displays tunnel setup instructions rather than hanging in the background.

USB-C Sideloading & Backup Gear
Provisioning GestaltX with SideStore, AltStore, Impactor, or iLoader and generating a Pairing file for App Audio Library requires a reliable wired USB data cable, while an external SSD keeps a clean off-device copy of com.apple.MobileGestalt.plist and full Finder/iTunes backups:
| Hardware | Role in GestaltX Workflow | Specification | Amazon |
|---|---|---|---|
| Anker 240W USB-C Data & Power Cable | Wired IPA signing & Pairing file capture | USB-IF certified USB-C data & 240W power lead | Check price |
| Apple 60W Woven USB-C Sync Cable | Mac / Windows sync & recovery restore | Woven 1m USB-C charge and USB 2 data cable | Check price |
| SanDisk 1TB Extreme Portable USB-C SSD | Off-device OriginalGestalt.plist & iOS backups | 1TB NVMe USB-C 3.2 Gen 2 (up to 1,050 MB/s) | Check price |
| UGREEN Revodok 10Gbps USB-C Hub | Multi-port USB-C & USB-A bridge for MacBooks | 10Gbps data ports with 100W PD pass-through | Check price |

Common questions
Why did Wallpaper Settings stop finding containers on iOS 27.3 before v1.0.7?
Apple adjusted container discovery behavior on iOS 27.3 Beta 1. GestaltX v1.0.7 (Build 11130112) and v1.1.1 updated container lookup so Wallpaper Settings and App Launch Images locate PosterBoard and app caches reliably on 27.3.
Why is an imported .tendies wallpaper still visible on my Lock Screen after deleting it in GestaltX?
As tracked in issue #126, GestaltX’s delete button calls deleteImportedWallpaper() to remove the pack from GestaltX’s local library. To remove an already-registered Lock Screen face, long-press the Lock Screen, swipe up on that wallpaper card, and tap the trash icon.
Why does App Audio Library ask for Pairing and LocalDevVPN?
Some third-party apps store or register notification tones in paths not enumerable from static metadata alone. Pairing + LocalDevVPN lets GestaltX observe and resolve the exact notification-sound path safely on-device.
