# Flashing custom firmware to artoo
This guide shows you how to flash a custom firmware onto artoo. Super useful if you've bricked it (see note at end) or have made a custom build. If you haven't already, you should see [building artoo's firmware](https://github.com/OpenSolo/documentation/new/master/artoo/build-artoo-firmware.md).
> Note: this was tested on an artoo flashed with OpenSolo and on an artoo just after a factory reset. Both appeared to work but ymmv. (your mileage may vary)
## Let's Start
Coming shortly...
First you need to connect to the `SoloLink_xxx` WiFi. Once you're connected you can start running the commands below.
Navigate to the artoo directory:
```
cd <open solo directory>/artoo
```
Make sure the firmware file has something in it:
```
du -h artoo.bin
```
Should output something like this:
> 236K artoo.bin
The next two steps will require you to enter this password when prompted:
```
TjSDBkAu
```
Copy the firmware over:
```
scp artoo.bin root@10.1.1.1:/home/root/
```
SSH into artoo:
```
ssh root@10.1.1.1
```
Run the flash tool:
```
updateArtoo.sh
```
Your screen should immediately turn off. You'll see lots of lines scrolling up the screen like below. DO NOT interrupt this process. Wait for it to finish, it will take a minute or two. You'll know when it's done because artoo's screen should turn back on.
```
root@3dr_controller:~# updateArtoo.sh
Bootloader version 22
Chip id: 0x414 (STM32 High-density)
Write 256 bytes at 0x8000000
Write 256 bytes at 0x8000100
Write 256 bytes at 0x8000200
```
Artoo should reboot. Well the WiFi stays connected and it's quicker then usual so I doubt it's actually doing a full reboot. If you're running open solo you should now see the new boot up logo and text strings. Do a full reboot for good measure:
```
/sbin/shutdown -r now
```
If you've customised it you'll be greeted with the custom image. Here's mine ;)

## Bricked artoo?
If you've soft bricked artoo it's normally pretty easy to fix. This generally happens when a bad `artoo.bin` is genereated by solo-builder then flashed. This method only works if that is what has happened. Also note a factory reset _does not fix this_ as it just reflashes the dodgy `.bin` file again.

This link is a copy of the "good" artoo.bin file I found on my artoo. This may or may not work on your controller but it is worth a try if your builds keep failing to produce a good `artoo.bin`.
