How to use SubGHz Remote app?

  1. Open app, press Back button, select New map file
  2. Configure signal files and their names for every button (also you can add only one signal and make other buttons empty - just don't select any files for them in config)
  3. Save new map file
  4. Open map file and select your previously created file
  5. Use buttons to send subghz signal files that you selected in map config at step 2

My desktop (pin, favourites, etc..) (or other) settings was reset to default after update, what to do?

Just configure that settings again, all is fine, and make sure you seen changelogs for the releases that came out after your previous version, when settings struct is changed, settings file are reset after update, this happens only when struct changes is required, so don't assume that settings will be reset in every release, this will happen only in specific ones

Why is flipper not connecting to chrome?

The most common cause of the flipper not connecting to google chrome is having qFlipper open while trying to connect your flipper. Or having second flipper lab page open at same time.

You must close qFlipper (or other flipper lab web pages) before attempting to connect your flipper to chrome.

No, and trying to do so with Read RAW will lead to key desync or unpair with blacklist which means re-pair is very hard and requires service tools

Nowhere, this is illegal in almost every country in the world

Your Flipper feels slow and unresponsive?

  1. Make sure you using good microSD card from known brand, flipper works with microSD via SPI that means not any microSD will work good even if it works ok with other devices
  2. Go into Settings -> System and make sure that you have Log Level = None Debug = OFF Heap Trace = None If some of that settings is set to something different - change it to None / OFF
  3. Make sure your battery is charged, that can affect performance too

NFC/RFID FAQ

From our good friend @Equip and @np0
------------------------------------------------------

MIFARE Ultralight

  • Scan the card, hold the Flipper Zero up to the reader to get the password to unlock the rest of the sectors, then scan the card again.

MIFARE DESFire/MIFARE Ultralight C

  • The Flipper Zero has no available attacks for this card currently.

Bank cards

  • You cannot clone bank cards
  • The Flipper Zero cannot emulate bank cards
  • The Flipper Zero cannot pretend to be a point of sale machine

Amiibos

  • NTAG215. that's it. It's not going on a MIFARE Classic.
  • Currently, you cannot write Amiibos to new physical tags. yet.

HID/iClass

  • Picopass iClass can be read using the Picopass reader plugin
  • 26bit Picopass can be downgraded to H10301 RFID credentials (note, it is not guaranteed to work if the reader is not configured to read low frequency)
  • Readers will need to be configured and have an LF RFID antenna in order to be read. Certain iClass readers are HF only, and do not have the ability to have LF configured
  • Emulation for Picopass was added on July 26th, and the updated version can be found in latest releases of Unleashed firmware with apps preinstalled, or in official Apps Hub via Flipper Mobile app
  • Write support for personalization mode cards is doable with app
  • The Seader app and a SAM expansion board < https://www.redteamtools.com/nard-sam-expansion-board-for-flipper-zero-with-hid-seos-iclass-sam/ > will allow reading more secure HID cards, which may be helpful in downgrade attacks

LF-RFID

If you're wanting to make clones of low frequency RFID chips you need to write to T5577's. "Blanks" do not exist. All of the chips the Flipper Zero can interact with are read-only and cannot be overwritten or purchased blank. T5577s are multiemulator chips that the Flipper Zero can program to be other tags

Unknown Card/Fob

If you have exhausted all options of scanning via NFC/RFID/PICOPASS then take a photo of:

  • The front and back of your credential
  • The reader you use with the credential
  • If your credential is a card, hold it up to a very bright light source e.g. a lightbulb and take a photo of the exposed antenna. This is useful for identification, post it for us to identify!
