Normally, you can only flash fastboot ROM on Redmi 3 only when the handset’s bootloader has been unlocked. Fastboot flashing is a great way to kick your device out of bootloop as well as to fix soft-brick problem. But what if your Redmi 3 device still has locked bootloader and you simply can’t wait to get official unlock permission from MIUI Developer Team? Can you still do the upgrade or flashing MIUI via Fastboot? The answer is, fortunately, yes.
Doing fastboot update may need more tricks than just Recovery update. However, at some cases fastboot flashing could simply inevitable. The steps below show you how to properly install MIUI 7.x fastboot ROM on locked Redmi 3 device. As what this article is meant to, please do not try these steps on unlocked device.

Installing MIUI Fastboot ROM
Step 1 – First ting first, turn off your Redmi 3 device.
Step 2 – On your computer, open up the MiFlash Tool you’ve just installed.
Step 3 – Now put your Redmi 3 device into Download Mode. I can say that doing so is not so easy. Nevertheless, you can try this: Press the Volume Up (+) button and the Power button at the same time for few seconds until you enter Download mode.
Step 4 – Then connect the device to your computer (PC/laptop) using its micro USB cable.
Step 5 – Make sure MiFlash Tool can recognize your device. It usually recognizes your device as COM10 or COM-something. The number will vary but it usually starts with COM. Otherwise, close MiFlash and then try installing Qualcomm QDLoader driver first.
Step 6 – Now in your computer, find the Fastboot file (.tgz) you have downloaded and extract it using WinRAR (or 7zip). The first time you will get a folder with a .tar file in it. Again, extract that .tar file. It means in this step you have to do file extraction twice.
Step 7 – You will then get a folder containing several files. Copy the path in Windows Explorer address bar.
Step 8 – Back to MiFlash Tool again. Now paste into the path from address bar copied in the last step into MiFlash address bar.
**ignore the 21761cfc device in the picture which is just an example. It should be COM10 or COM-something.
Step 9 – Click on the Refresh button. The tool should now recognize your device (circled in yellow above).
Step 10 – Make sure you select either Flash all or Flash all except storage from the option in the bottom.
Step 11 – Finally, click on the Flash button to start installing fastboot ROM.
Step 12 – Sit tight and wait for the progress bar to reach 100%. The process should take only few seconds to complete.
