Hi Fabio, I struggled with getting the fex file for the two A31 devices I have. The simplest way is to try to locate an update file for the device and try and extract it from there. Here is some discussions on IRC I had with Wens http://irclog.whitequark.org/linux-sunxi/2014-11-18#10892942. I didn't follow up on actually getting the fex from the device, my plan at the time was to dump the entire NAND image and run it through a hex editor to locate some obvious text from the fex file. Then I would of used that offset to extract it and pass it through bin2fex. Good luck, CK
