[Unlock][Note 3 SnapDragon] FULL INSTRUCTION FOR UNLOCK BOOTLOADER

Dear Owners of Redmi Note 3 (SnapDragon) !​By results of my experience of the positive unlocking of two phones, I propose for you the full instruction for unlock of bootloader and flashing of custom recovery (twrp-3.0.2-1-kenzo.img). This Instruction was compiled from information in Internet. You can download Instruction and all required files by links:
Instruction (pdf file):

It's working! But:
"DO IT AT YOUR OWN RISK. I'm not responsible For warranty Void or Bricks Phones."

Is this the official method?

No

I brick my phone doing this and now i cant unbrick... When i conect to USB a red led still flashing like edl mode but my pc doesnt recognize him...

No, the only official way now is to request Unlock Permission from the Xiaomi team
- http://www.miui.com/unlock/
i have unlocked using this method from the original thread. works fine now rooted
- http://forum.xda-developers.com/redmi-note-3/how-to/redmi-note3-prokenzo-guiderom-global-t3341102
i think TS should give credit to original thread. thank you

i hardbrick my device using your instructions ((( It is no working for me (( how i restore my device??
error on miflash
(0x80004005: FAILED(remote: device is locked. Cannot flash images)

It's no official method. Official method is the request to Xiaomi. I used this method by using Win 7 for two phones which were on MIUI 7.1.7.0 Global . And method should be used on only 64-bit PC. There are a lot of problem due to improperly installed drivers on PC or/and due to mistakes in flashing process (not following of instructions). For unbrick I propose to try some methods from Internet (MIUI forum and other). If result will be absent then only test points will help you.

Congratulations!!
You had a soft brick only! It was as a result of "not follow of instruction".
Please, be careful for flashing of MIUI !!!

Backup your EFS guys. I lost mine and still looking for a redmi note 3 qcn file to recovery my network. lol

Yep that what happened to me when I incorrectly flashed it.
I revived it using this method:
http://en.miui.com/thread-245347-1-1.html
It's actually pretty easy than it looks.

I followed your instructions and everything worked fine. If you get stuck in EDL Mode then boot to fastboot or Recovery and do a wipe.

Thank you a lot for this info.
The guy on Miui forums forgot a crucial part on his instructions and it was to enable OEM unlock. I failed twice when doing his tutorial and even hard bricked my phone. Lucky me I had the guts to test point it out from there.
With your instructions I finally did it and can remove this crappy, horrible iOS ripoff that is MIUI.
Also I'll start to give some kernel love to this phone very shortly.
Regards.

make the developer settings available, within it you will have oem bootloader authorization, you need to turn it on and theoretically ready

I reboot into bootloader and tried both "fastboot flashing unlock" and "fastboot oem unlock". None of them seems to be working. Do I have to use Mi Unlock tool?

this is a very good question! if I remember well, I read in another forum that you don't need Miunlock to just open the open bootloader in the developer settings, and then you can root it, and you just need to flash the ROM from the TWRP. to do this I think I need an OTG cable and a flash drive that you can flash, because you don't have a memory card slot

I have the same issue with the global version. I tried both "fastboot flashing unlock" and "fastboot oem unlock". I even tried Mi Unlock tool without any success. Also, they don't answer support tickets regarding unlocking the bootloader at blackshark site.
Any ideas?

Any one help me to unlock bootloader of black Shark 2 Chinese version?

Try flashing bootloader and gpt codes then give it a try.(note:- use the latest firmware to flash the bootloader and gpt, so your device won't get bricked)

Good!!! Do you follow this guide??? it worked for me

Hi there, I have the variant XT1680, I'm trying to get the key to unlock the bootloader but then something happened, the page says:
"PUID Not found in your identifier, please try again." and then it says: "Your device does not qualify for bootloader unlocking." What should I do?

Are you sure that bootloader is unlocked? (With unlocked BL you will see that message each time when you reboot: "Your device has been unlocked and can't be trusted").
Try to relock and then unlock the bootloader. (Sometimes the phone and other tools shows phone is unlocked and it is unable to flash recovery.)

As far as I know Potatonv method was made for Kirin 960/659/655. On 650 may or may not work correctly...
