To update Sub Phatty firmware:


Download the Sysex Tool software here:
http://www.elektron.se/sites/default/files/products/files/Elektron_C6_OSX_v1.4E.dmg (C6 for Mac)
http://www.elektron.se/sites/default/files/products/files/Elektron_C6_Windows_v1.4F.zip (C6 for Windows)

(or, use your favourite sysex sending utility if you have one)

IMPORTANT! -- DO NOT use a USB hub when performing this update.
The recommended way to do it is to connect a USB cable directly from your computer to the Sub Phatty.
You can also use standard (DIN) MIDI to perform the update; if so, make sure your MIDI interface has the latest drivers installed.  Because we can't guarantee that your MIDI interface will work properly, we recommend USB.


1) Press and hold the PITCH AMT, HARD SYNC, and ACTIVATE PANEL buttons on the Sub Phatty control panel. The buttons will blink in unison. 
2) Once again, Press and hold the PITCH AMT, HARD SYNC, and ACTIVATE PANEL buttons on the panel to confirm you wish to update the firmware.
3) You should see the MIDI LED (top left) blink on and off three times.  
4) After this, the LFO LED (top left) will start to blink on and off regularly indicating the unit is ready to receive new firmware.
5) Connect a USB cable from the Sub Phatty directly to your computer -- NOT through a USB hub.  
6) Open the C6 Sysex Tool software.
7) Select Sub Phatty as your MIDI output device from the Config tab
8) *IMPORTANT* in the C6 Preferences, "Misc Settings" section, set Turbo Limit to x1.
9) Click the Load button to open the Sub Phatty firmware file; select the file <SubPhatty_v_197_1_2_9.syx> and click Open.
10) Click the Send button to send the new Sub Phatty firmware sysex file.  You should see the MIDI LED blinking on and off slowly while the file is being transferred. DO NOT CLICK THE TURBO BUTTON or the update will fail.  In fact, don't click anything.  Just wait. 

When the firmware update is complete, the Sub Phatty will restart and will be ready to play immediately.  

TROUBLE SHOOTING:

If during the transfer (step 10) the MIDI LED begins to blink much faster than the LFO LED, this means that the transfer has failed.
If that happens, just restart your Sub Phatty (turn the power off and back on) and send the firmware file again. Verify your Sysex-sending settings before trying again.  
If you turn on the Sub Phatty and only the LFO LED is blinking slowly, with no other activity on the unit, this means the Sub Phatty bootloader is waiting for a successful firmware update. Make sure you're using good cables and your software is set up correctly, and send the firmware file again.

### After successful reboot, firmware update is complete. ###
