Hello, I'm trying to update MIUI version to my Xiaomi Mi Note 4G handset device. When I flash device with MiFlash Tool, I have got an error message, "unspecified-error-0xffffffff-fix". So I googling and I found a link, blog.doki.co.id/mengatasi-flash-xiaomi-mi4-muncul-unspecified-error-0xffffffff-fix and I follow the steps in this article. When I run **fastboot**.bat file and window asked me to format disk and I unexpected clicked "Format" button . And then, I power on the device and noting is appeared on the screen. When I check in window's explorer, it is showing a lot partition of the device.. May I know is it able to fix or to reinstall OS like computer? Thank you. Please help.
