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.
|
|
