If your firmware update is not successful - Caution
After you update the T1 ToneMatch Audio Engine or L1 Model II firmware, if you see a window on the PC that says the update was not successful, you should:
turn the L1 and T1 off
wait three seconds
then turn the L1 and T1 back on
Do this before trying the update again!
This allows the L1 and T1s to re-establish a good copy of the software.
Fixes a bug where some power outages could cause the T1 to hang. This is related to the problems reported on the message board where some users have experienced a loss of audio sometimes accompanied by a blank blue LCD screen.[1]
Scene Names
Fixes a bug related to scene naming where scene names over 17 characters would display incorrectly.
