Key Combos

There are times when your flipper feels blue and don't respond to your commands. In that case you may find this guide useful.

Basic Combos

Hardware Reset

  • Press LEFT and BACK and hold for couple seconds
  • Release LEFT and BACK

This combo performs hardware reset by pulling MCU reset line down. Main components involved: Keys -> DD8(NC7SZ32M5X, OR-gate) -> DD1(STM32WB55, MCU)

There is 1 case when it's not working:

  • MCU debug block is active and holding reset line from inside.

Hardware Power Reset

  • Disconnect USB and any external power supplies
  • Disconnect USB once again
  • Make sure that you've disconnected USB and any external power supplies
  • Press BACK and hold for 30 seconds (Only will work with USB Disconnected)
  • If you have not disconnected USB, then disconnect USB and repeat previous step
  • Release BACK key

This combo performs reset by switching SYS power line off and then on. Main components involved: Keys -> DD6(bq25896, charger)

There is 1 case when it's not working:

  • Power supply is connected to USB or 5V_ext

Software DFU

  • Press LEFT on boot to enter DFU with flipper boot-loader

There is 1 case when it's not working:

  • Flipper Boot-loader is damaged or absent

Hardware DFU

  • Press OK on boot to enter DFU with ST boot-loader

There is 1 case when it's not working:

  • Option Bytes are damaged or set to ignore OK key

DFU Combos

Hardware Reset + Software DFU

  • Press LEFT and BACK and hold for couple seconds
  • Release BACK
  • Device will enter DFU with indication (Blue LED + DFU Screen)
  • Release LEFT

This combo performs hardware reset by pulling MCU reset line down. Then LEFT key indicates to boot-loader that DFU mode requested.

There are 2 cases when it's not working:

  • MCU debug block is active and holding reset line from inside
  • Flipper Boot-loader is damaged or absent

Hardware Reset + Hardware DFU

  • Press LEFT and BACK and OK and hold for couple seconds
  • Release BACK and LEFT
  • Device will enter DFU without indication

This combo performs hardware reset by pulling MCU reset line down. Then OK key forces MCU to load internal boot-loader.

There are 2 cases when it's not working:

  • MCU debug block is active and holding reset line from inside
  • Option Bytes are damaged or set to ignore OK key

Hardware Power Reset + Software DFU

  • Disconnect USB and any external power supplies
  • Press BACK and LEFT for 30 seconds
  • Release BACK
  • Device will enter DFU with indication (Blue LED + DFU Screen)
  • Release LEFT
  • Plug USB

This combo performs reset by switching SYS power line off and then on. Then LEFT key indicates to boot-loader that DFU mode requested.

There are 2 cases when it's not working:

  • Power supply is connected to USB or 5V_ext
  • Flipper Boot-loader is damaged or absent

Hardware Power Reset + Hardware DFU

  • Disconnect USB and any external power supplies
  • Press BACK and OK and hold for 30 seconds
  • Release BACK and OK
  • Device will enter DFU without indication
  • Plug USB

This combo performs reset by switching SYS power line off and then on. Then OK key forces MCU to load internal boot-loader.

There are 2 cases when it's not working:

  • Power supply is connected to USB or 5V_ext
  • Option Bytes are damaged or set to ignore OK key

Alternative ways to recover your device

If none of the described methods were useful:

  • Ensure battery charged
  • Disconnect battery and connect again (Requires disassembly)
  • Try to Flash device with ST-Link or other programmer that support SWD

If you still here and your device is not working: it's not software issue.
