Some users have been requesting us to post a tutorial on how to restore hardbricked Xiaomi Mi4i smartphone. So I’ve spend some time lurking and found this method, which as far as I understand helped some people. If you can’t turn on your Mi4i, it doesn’t boot into recovery or fastboot mode and when you connect it to PC it is recognized as “Forge HS-USB QDLoader 9008”, you can try the steps below to fix it.
