I'm not sure how I managed this but it seems I've somehow borked my GT22 and cannot get into firmware update mode.
Trying to upgrade from 2.2.0 to 2.3.1...
Unziped the firmware and put MMGT231.rjf file on a thumb drive (only file on drive)
Booted the unit holding the two little black buttons under main display
I believe LCD#1 changed to:
MMGTB Boot v1.0
Awaiting download...
Put my thumb drive in nothing happened...
Anyhow, in some combination of retrying my entire top row got toasted...
LCD#1 would display the same message on boot even without holding the buttons down:
MMGTB Boot v1.0
Awaiting download...
Buttons #2, #3, #4 were blank rather than my settings but main display was my normal first song
Pressing the two little buttons under the display would not enter setup, they didn't seem to work at all
Funny thing is rest of rows continued to display and function fine with my previous settings.
To get into setup grabbed my backup from PC editor and added another page with the setup IA
This allowed me into Setup on the GT22 and I performed a factory reset however no change for top row
Finally tried "Update Button FW", each row briefly showed the update message:
MMGTB Boot v1.0
Programming...
Unit now appears to be functioning normally again... AWESOME!
Everything on top row displays, buttons #1-4 work, little black buttons can get me into setup
Now for the life of me cannot get it to try to update firmware again...
I hold down the two little black buttons and power up
main display comes up to my 1 song as usua
If I don't let go if the buttons they eventually go into setup
I've tried inserting 4 different thumb drives...
Tried both the 2.3.0 (MMGT230.rjf) and 2.3.1 (MMGT231.rjf) firmware versions
Thumbdrives are formatted fat32, and the .rjf file is the only file on the thumbdrive
I can use the thumbdrives to restore a .rjs save from my workstation so know port and sticks are good
One of the thumbdrives I used when upgrading to 2.2.0
Sorry for the novel, hopefully missing something simple and someone can point me in right direction
Cheers
