Announced in March 2016, the Xiaomi Redmi Note 3 Pro has been an absolute success in the budget phone market. That said, the Redmi Note 3 Pro Special Edition is quite the catch for mobile enthusiasts out there.
If you don’t want to wait for the official bootloader unlock process for the Redmi Note 3 Pro SE, thanks to XDA Junior Member Heisenberg00, users can unofficially unlock the bootloader. Here’s how:
Note: This guide will only work for the Snapdragon Chip variant of the Redmi Note 3 Pro SE.
- A Windows PC
- USB Cable (double-check for faults)
- At least 60% battery remaining on your device
Unlocking the Bootloader
Note: This will wipe all data on your device. Make sure you backup important files as necessary before proceeding.
- Download the .rar from the attachment from here and extract it to C:\ directory.
- Enter bootloader mode on your device by Power button and Volume down button simultaneously.
- Connect your phone to your PC using a USB cable.
- Enter EDL mode by following the instructions bellow (via @emuzychenko) ;
- Most of the Qualcomm based PDAs support Emergency Download (EDL) mode allowing users to unbrick their device, unlock bootloader or modify device parameters. Since FastBoot command protocol is simple and text-based, it is enough to send a packet containing “reboot-edl” text via USB. The simplest way to do that is to patch Windows fastboot.exe file, replacing “reboot-bootloader” text with “reboot-edl”. As “reboot-bootloader” string is found in the command line, fastboot.exe sends the same constant string to the device. So if “reboot-bootloader” is replaced with “reboot-edl”, you can specify “reboot-edl” in the command line and the same text will be sent to the device. With the attached fastboot.exe, successfully rebooted to EDL mode (9008) and re-flashed proper partition images.
- Start MiFlash and select the folder you’ve extracted the file to (C:\RN3_unlockblonly).
- Press refresh to see that your phone is connected and hit Flash. Wait for a few seconds.
This should unofficially unlock your device’s bootloader.
