Phone Moto X, "Ghost" 2013, 1st-gen., Developer's version and unlocked with Motorola code.
Maybe this is not supposed to be cleaned off, but thought I'd ask as I am far from an expert with this stuff. I am moving up from CyanogenMod cm12 to cm13 and it is strongly suggested to clean before an install up to the next level.
Using TWRP "wipe" and selecting everything, I get this error...
Formatting USB OTG using mkdosfs... process ended with ERROR=1 unable to wipe '/usb-otg'. unknown MTP message type: 1 unable to wipe '/usb-otg'.
I searched online and found a Fastboot command using '$ fastboot format userdata' on a Ubuntu PC (with ADB) that returned the same error after completing the format.
How can I get a complete clean system to start with?
