Install 5Ghost WiFi Lab on your Flipper Zero
Install the 5Ghost WiFi Lab companion app onto your Flipper Zero straight from this page — over the Flipper's own RPC protocol, no qFlipper and no SD-card removal. 5Ghost WiFi Lab drives a 5Ghost BW16 board on the Flipper's GPIO header. You need Chrome, Edge or Firefox 151+ on a desktop computer and a USB-C data cable.
Installs the latest 5Ghost WiFi Lab release from the official repo — the exact version is shown in the flasher above.
How does browser app-installation work?
Connect the Flipper over USB and click Connect. The page opens an RPC session, reads your firmware version, then writes the application file (.fap) to /ext/apps/ on the SD card — exactly what copying the file with qFlipper would do. When it finishes, open the app from the Apps menu on the device. No firmware is changed.
Which browsers can talk to a Flipper Zero?
| Browser | Supported |
|---|---|
| Chrome / Edge (desktop) | ✅ Yes |
| Chrome (Android) | ✅ Yes |
| Firefox 151+ (desktop) | ✅ Yes — first use adds a permission add-on |
| Safari (macOS / iOS) | ❌ No |
| Firefox (Android) | ❌ No |
Browser access uses the Web Serial API: Chrome and Edge on desktop, Chrome on Android, and — since Firefox 151 for desktop (May 2026) — Firefox. Safari and every browser on iOS are out; see Web Serial is not supported.
Troubleshooting
| Symptom | Fix |
|---|---|
| No Flipper in the port picker | Follow No serial port detected, then pick the STMicroelectronics Virtual COM Port. |
| "RPC session" stalls or times out | Close qFlipper, the Flipper mobile app, and lab.flipper.net; see Failed to open serial port. |
| App installs but won't open | The app is built for a specific firmware API version. If your firmware's API major differs, the loader refuses it — update your Flipper firmware (or install the build matching your firmware line). |
| Connect fails immediately | Unplug and replug the cable, then reload the page. On Linux you may need permission for the serial device (dialout group). |
About this installer
This page installs an application onto a Flipper Zero you own, using the device's documented Protobuf RPC protocol over Web Serial. The protocol implementation is original PINGEQUA code written from the public protocol definition; no firmware is modified and no third-party application binaries are bundled into this site. Each app is distributed under its own upstream license, shown on the app's own page.
Frequently asked questions
What does this install on my Flipper Zero?
It installs a PINGEQUA companion app (.fap) to the Flipper's SD card over the Flipper RPC protocol — no qFlipper and no SD-card swap. The app loader then discovers it automatically.
Does it change my Flipper firmware?
No. It only writes an application file to /ext/apps on the SD card; your Flipper Zero firmware is not touched.
Which browsers can install it?
Chrome or Edge on desktop, Chrome on Android, or Firefox 151+ on desktop. It uses the Web Serial API; in Firefox the first connection also adds a permission add-on. Safari and every browser on iOS cannot flash.
