+# How to change Flipper name:
+
+## Instruction
+1. Read [How to build](https://github.com/Eng1n33r/flipperzero-firmware/blob/dev/documentation/HowToBuild.md) and [How to install](https://github.com/Eng1n33r/flipperzero-firmware/blob/dev/documentation/HowToInstall.md) to know how to build and install firmware
+2. Follow how to build instructions to prepare all things before continuing
+3. Run release build to verify all is ok - `./fbt COMPACT=1 DEBUG=0 updater_package`
+4. Clear build files - `./fbt COMPACT=1 DEBUG=0 updater_package -c`
+5. Run command with extra enviroment var before `./fbt` that variable should contain your custom name in alphanumeric characters - max length 8 chars
+ `CUSTOM_FLIPPER_NAME=Name ./fbt COMPACT=1 DEBUG=0 updater_package` - where `Name` write your custom name
+6. Copy `dist/f7-C/f7-update-local` folder to microSD `update/myfw/` and run `update` file on flipper from file manager app (Archive)
+7. Flash from microSD card only, .dfu update from qFlipper will not work properly since name and serial number will be changed
+8. Done, you will have custom name, serial number and bluetooth mac address
+
+
+
+## Troubleshooting
+### I'm using Windows and name changing / building firmware doesn't work
+- Use PowerShell or VSCode terminal(powershell by default)
+- Clear build files - `.\fbt.cmd COMPACT=1 DEBUG=0 updater_package -c`
+- Enter this in same terminal `$Env:CUSTOM_FLIPPER_NAME="Name"`
+- Run release build - `.\fbt.cmd COMPACT=1 DEBUG=0 updater_package`
+- Flash as described before (see 6.)
+- If something still not work - Run powershell or VSCode as Admin
+### Name stays same for every new build
+- Clear build files - `./fbt COMPACT=1 DEBUG=0 updater_package -c`
+- Try again
+### I want to return my original name and serial number
+- Flash stock FW or any CFW using microSD card offline update method
+
+Or
+- Clear build files - `./fbt COMPACT=1 DEBUG=0 updater_package -c`
+- Run release build - `./fbt COMPACT=1 DEBUG=0 updater_package`
+- Copy `dist/f7-C/f7-update-local` folder to microSD `update/myfw/` and run `update` file on flipper from file manager app (Archive)
+- Flash from microSD card only, .dfu update from qFlipper will not work properly since name and serial number will be changed
