FAQ: Xiaomi Redmi 3S/Prime hard Reset [ flash Redmi 3s/Prime]

1.After clicking the ‘Download’ button, the device restarts normally. What will I do now?

ANS: Me too faced the same issue. After clicking the download option [step no.5] my device restarted normally. The device is not going to EDL mode. And it is compulsory to boot to EDL mode to continue further steps. So how to get my device into EDL mode?

There are some methods to put your device into EDL mode. The method I followed is like this:
First take one another Micro USB cable [don’t use your original Xiaomi Micro USB cable]. Then cut off it’s plastic cover, and you can see some coloured wires there. Pick the green and black wires.Now take a needle and pierce through the green and black wires. So there will be a contact between green and black wires. Make sure that there is a connection[contact] between the two wires.

Now switch off your device and connect the new altered Micro USB cable to PC and plug the other end [end which connects to the phone] to your phone. Now wait for 15 seconds[you won’t see anything]. After counting 15, pull away the micro USB cable from the device. Congrats, Now your phone is booted into ‘download’ mode.
Now take the original Xiaomi micro USB cable and connect to the PC and device. After that continue from the steps from step no.6.
This is worked fine for me. If you have any doubts in this steps, you can check this video which explaining this method[ booting device to EDL mode with altered micro USB cable]. If this method didn’t work for you then you can also check some other methods to boot your device into EDL mode.
