USB UPDATE INSTRUCTIONS:
(If your Little Phatty Stage Edition does not have a USB port, skip this step and proceed to the Firmware Update Instructions below.)

Connect USB from your Windows computer to your Little Phatty's USB port.
On your computer, launch the application "LP_USB_v33.exe"
Type the number corresponding to your LP's USB MIDI connection - it will be called either Little Phatty SE II (Win7, Vista) or USB Audio Device (winXP,98).
Press Enter to begin the transfer.  Wait until the transfer is complete.
On the LP, you should see "USB UPGRADED" on the LCD screen.
Press MASTER or PRESET on the LP to clear this message.
Press Enter on your computer to exit the USB upgrade utility.

FIRMWARE UPDATE INSTRUCTIONS:

In order to send new firmware to the Phatty, it must be running in “bootloader” mode.

To enter this mode, turn off power to the Phatty, then press and hold the MASTER button while turning on the power.  You should see the following on the LCD:

Update Firmware?
PRESET = Yes

Press the PRESET button to confirm that you want to update the firmware.

Connect MIDI from your computer to the Little Phatty. 
You can use the Phatty USB port if you have one, or use a third-party MIDI interface.  
If using a third-party MIDI interface (such as the M-Audio MIDISport series or similar), 
make sure you have installed the latest drivers available from the manufacturer before attempting to send this firmware update.  
Attempting to send this firmware update with outdated drivers could result in failure.

On your computer, launch the program "PhattyLoader.exe."  This will open the Phatty Firmware Updater.
Go to the Device menu, and select your MIDI output device.  This will be Little Phatty or USB Audio Device if using USB direct to the Phatty; 
otherwise you should select the MIDI output device which is connected to your Little Phatty's MIDI IN port.

Click "Update Firmware" to send the firmware to the Little Phatty.
Watch the Little Phatty LCD; you should see "Receiving... Record #" 1, 2, 3...
The number of Records will count up until completion (about 235 records at the standard Timing settings).
When the update is complete, your Little Phatty will reboot to the new operating system.

**IMPORTANT** 
After you have loaded the new operating system successfully, 
you must turn off the power to the Little Phatty and turn it on again before MIDI will work properly.
Once you cycle the power in this way, your LP firmware update is complete.

Enjoy the new features!

(END of update procedure)

TROUBLESHOOTING:

If you get a Checksum Error during the PhattyLoader update process, do the following:
Turn off the LP and turn it back on again.
Close and re-open the Phatty Loader software.
In the PhattyLoader, go to the Timing menu and try setting the Packet Size to 128 bytes (half) and the Timing Interval to 500ms (slow).
Then click Update Firmware to try again.  
You can repeat this process as many times as you need to, experimenting with different Timing settings, if necessary.  It should "just work" the first time.
