echo:SD init fail error with GT2560 A+ on my I3 Pro B

[geetch38349]

Can someone help me figure out why my I3 Pro B will not load up with the available firmware?

The only significant change is that I had to replace the stock GT2560 A with a new GT2560 A+ control board. I have tried a few different firmware available in the Geeetech forums with no luck. I can confirm that all of the hardware will function with the old board. However, I wish to update boards.

The reason for the change in boards is that I've replaced the original board in order to store my settings via the EEPROM and the lack of bootloader on the original prevents an change in the firmware.

I’ve tried the following because they specify that they work with the GT2560 A+ (however none will boot up up for me)

All steppers work and can be operated via Repetier-Host manual. I really believe the issue is with the LCD/SD Reader.. I've tried both (attached)

Cancel my question. The problem is that the ribbon cables have to be reverse from the original position by shaving down the guides.
