justcrash Posted March 26, 2014 Share Posted March 26, 2014 Ok, I was trying to install the Glen DeLaune tones I purchased and the software freaked out. Finally I attempted to do a reset, first by holding down the left arrow and powering it on (this did nothing) and then I tried to roll back my flash version, with the thought process that I could then reinstall the latest flash version. After several failed attempts, the LCD on my 500 is now stuck on UPDATE FLASH. I could really use a hand. :( Quote Link to comment Share on other sites More sharing options...
duncann Posted March 26, 2014 Share Posted March 26, 2014 Maybe a long shot, but you could try unplugging everything (except power) and then again try powering on while holding left arrow. If that doesn't work maybe try another power outlet on a different circuit (maybe even a different house?). Quote Link to comment Share on other sites More sharing options...
justcrash Posted March 27, 2014 Author Share Posted March 27, 2014 Left arrow does nothing, nor do other USB cables/ports. :( Quote Link to comment Share on other sites More sharing options...
duncann Posted March 27, 2014 Share Posted March 27, 2014 Then sadly, it sounds like it's bricked. :( You'll probably have to get it serviced by a Line 6 repair center, probably not a fun process. Or if you have an alternate power brick to try (9VDC, 3A)? Does holding the right arrow while powering on do anything? That should bring up the calibration screen.

justcrash Posted March 27, 2014 Author Share Posted March 27, 2014 Yes it goes to the calibration screen (I tried that because I read somewhere that holding down the right button goes to a "safe mode"). Quote Link to comment Share on other sites More sharing options...
silverhead Posted March 27, 2014 Share Posted March 27, 2014 While in the test mode screen, select REFLASH (or FLASH). Then run Line 6 Monkey and reinstall the firmware. Quote Link to comment Share on other sites More sharing options...
justcrash Posted March 27, 2014 Author Share Posted March 27, 2014 While in the test mode screen, select REFLASH (or FLASH). Then run Line 6 Monkey and reinstall the firmware. What is the test mode? Can you walk me through, per chance? Quote Link to comment Share on other sites More sharing options...
duncann Posted March 27, 2014 Share Posted March 27, 2014 Test mode is the calibration screen. So select FLASH with the arrow pad. After that I'm not sure. If you press the view button while FLASH is selected, the screen blanks and displays the word 'flash' in the upper left corner for less than a second, then goes back to the calibration screen with the letter P after the word FLASH. The same thing happens if SDRAM is selected. I think what silverhead is saying is exactly what he stated. 1. Bring up the calibration screen 2. Select FLASH with the arrow pad (down arrow) 3. Reflash the device using Line 6 Monkey. 3 Quote Link to comment Share on other sites More sharing options...
stapleys Posted March 26, 2016 Share Posted March 26, 2016 I brought up the calibration screen and then went back to the Line 6 Monkey screen and reran the flash upgrade that worked for me. Quote Link to comment Share on other sites More sharing options...
