just an other thing : some rom are well ported (fish and chips, freerom ..) but other (miui, or joyos) not. It's because the structure of these rom are not like skatie rom structure. If you look at miui rom which have atheros driver, 1 - you have to correct the updater-script in meta-inf (assert failed : getprop(ro.product device..,) I did it by replacing the file updater-script by the file of skatie rom.
2 - after correcting this, an other problem : an error while flashing. I think it's because this rom have driver for atheros wifi in a directory /system/wifi which isn't present in skatie rom.
3 - the rom P771FV1.0.0B05-update_signed which is the stock rom of my french isp (zte blade S) doesn't works with zte tool but i don't know why
