So I found on an italian selling website a used moto G for 70€ (which is very cheap). The original owner flashed a wrong version of the cyanogenmod on it and now the phone is stuck in a boot loop, so he's reselling it. I don't know if I should buy it, considering the very cheap price and the phone's situation. Is it possible to reflash the original firmware on it and reset the phone to factory settings without any big problem?
