how far into goverlay does this happen?
Can you enter in firmware upgrade mode?
You could try to update the firmware, according to the manufacturer low usb voltage could of messed with it.
I can only provide an upgrade path within GOverlay, only if you can successfuly start the upgrade from GOverlay itself.
If you cant do it, please contact
coldtearselectronics@gmail.com requesting an alternative upgrade method.
To do it from GOverlay:
disconnect the unit.
open goverlay,
select in the lcdsysinfo 3.5'' tab an empty profile (or create one) so it doesnt request to draw anything to the display. hit apply.
go to update firmware from file in the tools section, select the fw file. DO NOT CLICK OPEN
connect lcdsysinfo
click OPEN
see if the device is detected in firmware mode and continue with firmware upgrade
