Hi All,
I am also facing the same issue, this only happened after the firmware upgrade to 2.62, untill this afternoon everything was working just great...
Have done all the above, have noted a few things strange though. My USB firware (though after upgrading to 1.04) shows V0.00 in the system i/o settings. Then i reinstalled it again to 1.4 (via monkey, strangely in monkey it shows as 1.4 version installed in POD HD) ...it shows for sometime and then vanish back to V0.00 after a couple of system reboots. This I think was one of the reasons i could not rollback to lower versions of Firmware. It kept giving the error Error 80007211, where it said it couldnt communicate with the device, or the device was not responding. I just cannot rollback to earlier version now (have tried it via monkey and manually selecting the files as well)
I checked the forum to rollback USB firmware, but it seems there is no option to do so (please correct my understanding if not so). My Flash firmware version shows 2.62 whereas it never showed me a message that it was sucessfully upgraded.
The other thing i noticed is after rebooting to global preset reset, it shows son of plexi patch, it allows me to edit it, but as soon as i hit any button in the lower row (FS5 to Tap Tempo) the unit FREEZES (HANGS) and then i am not able to anything other than reboot.
As a part of what has been recommended above, i have also tried to install/reinstall Monkey and other Drivers a couple of times, with no sucess to either sound coming from the unit or abe able to rollback to lower versions of firmware. I have done global preset reset and all the steps that have been mentioned above. The expression pedal calibration does not work for me (right arrow and power button) the value just sits to 0 even though i rock the pedal.
The power adapter and the USB cable cannot be an issue as my laptop detects Line 6 as a digital audio interface as soon as i connnect it.
I Need HELP !!!!!! I have a gig coming up and cannot afford to lose it ...i have no back up :( :( :( :( and i am terribly upset because of this issue.
Need help!!!! Is there an option to wipe everything damn thing and start new???
