Here is the video guide to Unlock Bootloader of Redmi Note 3.

So this way you can easily unlock the bootloader of your Redmi Note 3. I hope you will be able to unlock bootloader through this guide. Foe any queries leave your comments.

Great news for all Redmi Note 3 users. It is now possible to unlock RN3 bootloader without applying for official permission from MIUI Developer Team. For your information, normally, users need to submit their applications in order to get unlock permission. Usually, the review process takes approximately two weeks to finally come with a decision whether the application is approved or is not. There are several phone models come shipped with unlocked bootloader, due to the policy set by China government, including Mi 5, Mi 4c, and of course RN3. Luckily, for RN3 users can have a shortcut to release the bootloader lock placed in the system of their phones.

RN3 has been one of popular Android phones in Q1 of 2016 as the most features-rich and sophisticated-specs phone but its price is very affordable. It came earlier than the flagship Mi5. Interestingly, Xiaomi has even made the phone available in two variants: MediaTek-powered or Qualcomm-powered. Both chipsets are offering distinctive performance but then it’s up to customer’s preference on which one is the most preferable.

The trick you read in this page shows you how to unlock RN3 bootloader within 1 minutes * and without waiting for Xiaomi’s permission. However, you have to proceed carefully since there are possibilities for your device to brick. Therefore, I held no responsibility of anything that would happen to your phone as a result of following this guide. As usual, always take full backup of your phone before you proceed more further.

* Assuming you have all requirements and prerequisites fulfilled.

Personal advice: Despite its easiness and its fast process, it is better to use this method only if your unlock permission was rejected. However, you may also use this method immediately if you are really sure on what you’ll do and you are aware of its risks.

Update:

It is now possible to temporarily unlock RN3SD bootloader with no official permission. However, if your plans are to flash TWRP and flash Super SU to gain root, then you better follow another guide which is much more safe (brick-free method). Read : How to root locked Redmi Note 3 Snapdragon.

  • Download RD3 bootloader unlocked package (there are two .zip files: AnF.zip and Unlocked_Bootloader.zip).
  • A USB cable to connect your phone to PC.
  • Create full backup of your data.

Prerequisites

Couldn’t connect properly? Try disable and then renable USB debugging on your phone.

Step 4 – Now you need to reboot Redmi Note 3 into Download Mode (EDL Mode). Execute the command below :

  • Choose patch0.xml in the Patch XML File.

See picture below:

Step 10 – You should now have MiFlash configured but do not click the Flash button yet. Extract the Unlocked_Bootloader.zip file and you will get a file named emmc_appsboot.mbn – again, make sure you remember the output location.

Step 11 – Now in Windows Explorer, copy (Right-click > copy) then paste (Right-click > paste) that .mbn file into the Fastboot ROM folder. This will replace the original .mbn file. Confirm to replace if Windows asks you. P.s: before doing this step, it is recommended to create backup of original .mbn file and save it in another location.

Step 12 – Click on the Refresh button of MiFlash tool. Upon refreshing, your phone will be displayed as connected device at some COM port number.

Step 13 – Finally, click the Flash button.

Step 14 – Sit tight and wait for the flashing process to take place. It would be last any time within few seconds.

Step 15 – Once the process has been done, your phone will reboot and the MiFlash fastboot task has completed successfully.

Step 16 – Next, while your phone is still connected to PC, you have to reboot your phone into Fastboot mode now. You can achieve that by pressing Volume Down (-) button and Power button together approximately 30 seconds.

Step 17 – Go back to Windows Explorer and head to the folder of where you’ve extracted the AnF.zip file previously. Double-click the cmd.exe file to launch command prompt again.

Step 18 – Execute this command :

It will then show you current bootloader status.

Step 22 – That’s it. You can now safely disconnect your phone from PC.

Step 2 – Connect your phone to computer in Fastboot mode. Then issue command below :

Step 3 -Now reboot your device by typing :

That’s all. You can now disconnect your phone.

Additional Notes

  • Do not, and never, flash MIUI Recovery ROM (.zip) via either Mi Recovery or TWRP because it has stock bootloader (which is locked). Unfortunately, doing so will not relock bootloader properly but lead your phone to bootloop issue.
  • Instead, you can flash MIUI Fastboot ROM (.tgz) via fastboot mode if you want to upgrade the system once newer version is released.
  • Do not flash TWRP unless flashing its .img file via fastboot. It will temporarily boot and then you can flash SuperSU to gain root.
  • Again, always proceed with caution.

I just received my Note 4X with MIUI Global stable 8.2.2.0 ROM. TWRP 3.0.3 (thanks to cofface) and lazyflasher-no-verity-opt-encrypt.zip are successfully installed and available.

Through reading few threads I’m very unsure to flash XIAOMI.eu dev ROM. I’d like to change to this one, because of Android 7 and the quality and support from XIAOMI.eu ROM’s which I kow from my former Redmi 3 Pro.

Hmm, nobody running EU on Note 4X? O.K. than I’ll give up and wait until working process/ROM is available.

PS: is there any chance to separate the threads for Note 4 and Note 4X?

Today I have successfully flashed the Xiaomi Redmi Note 4 Qualcomm with the Xiaom.eu Weekly ROM. Here is how I did it:
1) Unlocked the bootloader.
2) Booted into fastboot mode (volume DOWN) and installed TWRP (mido) with adb.
Used commands:
fastboot devices
fastboot flash recovery twrp.img
fastboot reboot (hold volume UP)

3) After booting into TWRP, choose for Wipe > Format Data.
4) After that go to Advanced > ADB sideload and sideload the update.zip file. Don’t forget to Wipe Dalvik Cache and Wipe Cache.
Used command:
adb sideload update.zip

5) After installation, go back to Wipe and choose Factory Reset.
6) Reboot System.

Normally the Xiaomi Redmi Note 4 Qualcomm and Xiaomi Redmi Note 4X can run the same ROM because they have the same codename (mido).

Tried last two days to get it into EDL (Tespoint method) but it’s recognized as "HS-USB 900E" instead of "QDLoader 9008"

Any idea how to fix it? Me not. Deepflash did not work, no chance to go into fastboot or other mode using power an volume.

the mobile is completely dead. The Bootloader was shown as "unlocked" before I flashed the DEV-ROM. Without TWRP everything worked fine for 2 weeks. But unfortunately I wanted to have TWRP

I opened the mobile and tried to set it to EDL, red LED was flshing and it was recognised as "HS-USB Diagnostic 900E". What I need to flash with MiFlash is "HS-USB QDLoader 9008" instead.

to recover your device, I advise you to flash the fastboot ROM for your Xiaomi Redmi Note 4X with the XiaomiFlash tool.

If your device is connected with your PC as HS-USB Diagnostic 900E, go to Device Manager > Don’t search I will choose the driver to install > Let me pick from a list of device drivers on my computer > Look for the manufacturer "Qualcomm Incorporated" > Choose the latest "Qualcomm HS-USB QDLoader 9008" driver from there and install it. After installation, the device will be seen as Qualcomm HS-USB QDLoader 9008 device and can now be flashed with the XiaomiFlash tool.

You need an unlocked bootloader and TWRP if you want to install the Xiaomi.eu ROM.
