Hi!
I´m on hardware 2.72 and have tinkered with some of the alternative firmwares last time I could properly use it. What then came was the FatFS FAIL error each startup and the unability to use either the normal or the dfu disk in windows/linux/os x and the inability to format it…
I can´t even save to the internal disk when using the dso.
What could help in such a case? reflash from scratch using usb to ttl?
