*** Disclaimer ***

I'm not responsible of any issues that could happen while you are upgrading your amp.
I have made this video based on my personal experience to help out my Katana friends out there.
Please perform the update responsibly.

Caution when performing the update:
Never power-off your KATANA while the update is in progress!
If a power failure or similar accident occurs during the update process, the KATANA won't be able to start up in normal

operating mode. This will require servicing and contacting the nearest Roland service center if this occurs.

First thing:

Go to Boss Support and select your amp to download the Firware Software Update:

Get the file: KATANA SYSTEM PROGRAM (VER.3.02)

Open and extract the downloaded "katana_sys_v301.zip" file on your computer to get the two update files named "ROMINFO.TXT"

and "KATANARM.BIN" in the "katana_sys_v301" folder.

You must not rename the extracted files.

Adjust the [ MASTER ] knob to minimum.

* Do not connect the KATANA and the computer yet.

Turn the POWER switch on while holding down both the [ CH1 ] and [ PANEL ] Tone Setting buttons.

The indicators for the [CH1] to [CH4] buttons will start to flash. 50W owners, only [CH1] & [CH2] will flash

Connect the computer to the KATANA's USB port with a USB cable. Make sure the other end of the USB
cable is also plugged into the computer.

When the USB cable is inserted, the indicators for the [CH1] through [CH4] buttons will stop flashing and stay lighted.

And a "BOSS_KATANA" drive will appear on your computer screen.

Open the BOSS_KATANA drive.

Take note that, if your Katana doesn't pop automatically as a drive during the setup, just go to your file explorer and open it from there.

"Removable Disk (*:)" may appear instead of the BOSS_KATANA icon.

Copy or "drag and drop" all the files included in the "katana_sys_v301" folder into the "BOSS_KATANA" folder.

* Do not copy the "katana_sys_v301" folder, only the files in the folder.

Disconnect the BOSS_KATANA from the computer.

Disconnect the USB cable.

The [PANEL] button flashes.

Press [ PANEL ] button to start the update process.

While the update is in progress, the "EFFECTS" indicators light up.

When the update has finished, the "EFFECTS" indicators slowly flash simultaneously.

Turn the KATANA power off.

This completes the update operation. The new system program runs at the next startup.

Go get the latest Boss Tone Studio Software to be able to dig deep into the new features of the installed firmware v3.02.

Also, it's the time to plug your guitar and rock the f**k out!!! Rock on everyone. Hope it helps!
