# 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.
