I bought the Mi3 last week I changed the ROM to the developer then I changed again to Multilang ROM. I found that I cannot copy the ROM to the phone by USB cable connect to computer any more (but small files I still can). Now I want to come back to the Original how I can do? I have already back to the developer ROM already. But from Developer ROM to Stable ROM I cannot, it appeared "errors" in the end of "install update.zip to system one" Could you please help me.
