Momentum Firmware for the Flipper Zero: Installation, Features, and Configuration

Momentum is one of the three major community firmware forks for the Flipper Zero, alongside Unleashed and RogueMaster, but it takes a noticeably different philosophy from the other two: instead of stacking in every experimental feature and app the community produces, Momentum focuses on stability, sane defaults, and quality-of-life fixes on top of the official firmware, while still unlocking the region restrictions and extras most users actually install custom firmware for in the first place. This guide covers installing Momentum, what actually changes versus stock and the other forks, and the settings worth adjusting after your first flash.

In practice, Momentum tends to have fewer of the "it worked yesterday, now it soft-bricks" reports that show up after big Unleashed or RogueMaster updates, because the maintainers rebase on official firmware releases quickly and are more conservative about merging unstable community apps into the base build. That stability comes at the cost of a slightly smaller bundled app catalog — though nearly everything missing can still be sideloaded from the Flipper app catalog or built from source.

Before You Flash: Back Up Your Flipper

Any firmware change is a good time to make sure you have a recent backup. Open qFlipper, connect your Flipper over USB, and use the backup function to save your current settings, saved sub-GHz/NFC/IR files, and keys to your computer before doing anything else. If you're moving from stock firmware, note that some official-firmware saved files (particularly certain NFC dumps) may need re-scanning after switching to a database format used by custom firmware — back up the raw files regardless.

Installing Momentum

There are two supported install paths:

Web installer: Momentum publishes a browser-based flashing tool (built on the same WebUSB/WebSerial tech as the official Flipper web updater). Connect the Flipper over USB, put it in DFU/bootloader mode if prompted, and the installer handles downloading and flashing the latest release directly from the browser — no local software required.
qFlipper + manual firmware file: Download the latest .tgz or .dfu release from the Momentum GitHub releases page, open qFlipper, and use "Install from file" pointing at the downloaded firmware. This path is useful if you want to pin a specific version rather than always taking latest.

Either method takes 2–5 minutes. The Flipper will reboot into recovery/bootloader mode automatically as part of the process — don't disconnect the USB cable until qFlipper or the web installer reports the flash is complete.

First Boot After Flashing

On first boot into Momentum you'll be walked through region and unit settings. A few things worth setting deliberately rather than accepting defaults:

Sub-GHz region: Momentum ships with the region lock removed by default, meaning it will transmit and receive on frequencies your local firmware build would normally block. This is a legal gray area in some jurisdictions — see the note below.
Favorite apps (short-press and long-press): Momentum lets you bind two apps directly to the front d-pad OK button for instant access — worth setting to whichever tool you use most (Sub-GHz, NFC, or GPIO, for example).
Lockscreen and pin code: If the Flipper leaves your bag or bench, a lockscreen PIN prevents casual access to saved keys and cards.
Sleep/idle animation and screensaver timeout: Momentum exposes finer-grained control over backlight and sleep timing than stock, which matters for battery life if you carry the Flipper daily.

Updating and Rolling Back

Momentum auto-checks for updates from within the firmware and can update over USB via qFlipper or the web installer using the same process as the initial install. If a specific release causes problems, you can always flash an older .dfu from the GitHub releases page the same way you flashed the current one — there's no need for a full factory reset to change firmware versions, though it's good practice to re-backup before rolling back in case saved file formats changed between versions.

Troubleshooting a Failed Flash

If a flash is interrupted (USB disconnect, browser crash) and the Flipper won't boot normally, it's very rarely permanently bricked. Hold the back and left buttons simultaneously to force it into DFU/bootloader mode manually, reconnect to qFlipper, and re-run the install — qFlipper detects a Flipper stuck in bootloader mode and offers a repair-flash option automatically.

A Note on Legality

Removing the sub-GHz region lock means the Flipper can transmit outside the frequency bands and power limits your local regulator (FCC in the US, ETSI in the EU, etc.) permits for unlicensed devices. Transmitting on unauthorized frequencies isn't just a firmware setting to flip casually — interfering with licensed services (garage door systems sharing bands with other equipment, emergency services adjacent bands, etc.) can carry real regulatory penalties. Use the unlocked range for receiving and analysis, and be deliberate about what you actually transmit and where.

Momentum's appeal comes down to being the firmware that behaves the most like "stock, but unlocked" — if Unleashed or RogueMaster have ever felt overloaded with apps you don't use or flaky after an update, Momentum is worth trying as the more conservative alternative that still gets you the region unlock and extras most people install custom firmware for.
