Just saw this ref software version on the Boomerang
Determining exact software version
To verify which software version has possessed your III, hold down the loop 1 button and yellow Bonus button through out the entire
power up sequence (about 10 seconds). You’ll end up with the clock’s center light on and possibly one other light. Release the buttons.
Press loop 1 to see the first digit of the software version; the clock display shows you. Release and press loop 2 for the second digit.
Release and press loop 3 for the third digit.

** DO NOT begin a download until your III has completed its initialization & power up sequence - This takes at least 10 seconds.
** If a download renders your III inoperable, all costs associated with fixing it are your responsibility. ** Downloading software is NOT covered by warranty. ** This is necessary due to the unpredictable nature of using a wide range of computers, operating systems, drivers and hardware interfaces. Having said that, hundreds of customers have performed software downloads without a problem. In fact only 5 have actually “bricked” their pedals.
