Unlock Bootloader Without Waiting for permission from Xiaomi[Snapdragon Variant]

There is a long wait for unlocking the bootloader for Redmi Note 3. We have to apply and wait for permission for 2-3 weeks. Some people are having problems with that. Even after users get the permission, they are unable to unlock because it gets stuck at 50%.
A moderator on unoffical Miui India forum has found a way to unlock the bootloader without need of any code or confirmation from Xiaomi. This method DOESNT involve Mi Unlocking tool. Many users have tried it and unlocked their bootloader successfully and quickly.
Edit - If you are an Indian user with the Snapdragon variant and if you have got permission from xiaomi and want to unlock by official method then you will need to flash China developer rom by mi flash. You will able to unlock bootloader on China dev rom by official method. Some users have also been able to unlock officially on Global developer rom. So take your pic. But don't waste your time on Global stable... Official method of bootloader unlocking will NEVER work on Global stable.
(I will update the OP if by miracle people are able to unlock officially on Global stable. Chances are very slim though.)
The method given below is for other global or beta rom users for whom normal unlocking is not working or those who are too impatient to wait for confirmation sms from Xiaomi. [emoji48]
Edit 2 - I HIGHLY RECOMMEND you to try this tutorial with GLOBAL STABLE FASTBOOT rom. People who have tried this on China dev or China stable have faced bricked devices.
Here is the forum link where bootloader unlock tutorial by hacking method is given.
http://forum.miui.co.in/forum/mi-de...5165-redmi-note-3-snapdragon-unlock-the-beast
Edit 3 - There is a difference between unlocking the bootloader by this hack and unlocking by official method. A big difference. I suggest you to read threads here and on miui forum as well to acquaint yourself with it.
Basically if you unlock bootloader with official method your system accepts it and causes no problems while flashing miui roms.
But if you unlock bootloader by this hack method, your system doesnt accept it fully and causes problems if you flash stock miui. Flashing miui without proper modifications will easily cause hard brick. My explanation was very simplistic but there are a lot of complicated things involved which go on at the system level.
If you decide to unlock bootloader by the hack method.. Read this thread on how to flash miui roms.
http://en.miui.com/thread-256464-1-1.html
Also you don't need to worry about CM and AOSP roms. Whichever method you use to unlock your bootloader, CM and AOSP will work good without causing brick. You only need to worry about miui roms if you have used hack method.
My personal advice to you is that you don't try this hack method unless you are fairly well acquainted with technology and won't go mad if your device gets bricked. A lot of people have faced bricked device and many of them are noobs and I feel sorry for them. So unless you are courageous enough and feel confident, don't try this method.
Wait till your device can be unlocked by official method. That is best for new people.
Edit - This thread is outdated now. It was made a long time ago when development was in its infancy. There are lots of good threads on xda that can help you out. Ignore this thread and don't consider it's information relevant anymore.

I can confirm this method works.

The method works,
Finally after days of searching

whether there is a chance for something like this for MTK variant (i stuck at 50% and I have no solution)?

There might be a chance but this shortcut method was developed by Indian developers. And since only Qualcomm variant has been launched in India, these particular developers can't help you out.
Maybe some other talented people with mtk variant can emulate this and develop a shortcut method just like this.

Keep that as a last resort.
Go to the miui forum and post your problem in the redmi note 3 section. Give as much detail as possible. What's working what's not. One of the moderators will surely help you out.

I unlock with china stable ROM.
after unlock, I flashed via recovery another stable ROM and AOSP ROM but all works well.
That means AOSP ROM free with lock?

all customs roms are free from lock, except xioami eu roms, all miui roms have a emmc file(inside that firmware folder) that relocks bootloader

Is this work with G5?

Can you explain it more detailed?
I've got an unlocked G4 with TWRP running. How to reset the phone to default? Are these steps OK?
- Add my original IMEI to your orjinalg4.qcn
- Execute commands from commands.txt
- Run QPST and flash orjinalg4.qcn
What about TWRP afterwards? Is it gone?

Nowhere in his instructions did I see him flash a stock recovery image.
I presume this will work to Re-Lock the bootloader. But you would want to flash all stock images first rather than be stuck with a Locked device that will not boot your Unsigned Partitions.

But as I think, you can flash stock ROM with KDZ&TOT after this re-lock.

Well...could this IMEI change (assuming it works) be used to unlock the bootloader? Also I'm pretty sure this is illegal.

What you guys in real want ? Here is something real going on, depending on YOUR (XDA Comminity) feedback, full unlock guide for G4 and probably for G5 will come soon. Isn't this what thousends of users want ? "warloxfre" is a member of androidbrick.com and starting from the beginning all his works are for real.

This prodecure does have nothing to do with recovery (twrp), so NO, it will stay. This is just a trick (imei change). Ok, changing imei is illegal we ALL know that, but original imei will be written back after.

Any test subject?

Playing with imei is not dangerous at all if you know what you are doing. People who are not brave enough, just fallow this guide to backup your QCN first, then you are ready to test this..

I don't have half of the system apps... Bluetooth and NFC wont turn on too!

Hi guys! I tried root my Huawei P9 Lite VNS-L31 like 4 months ago, and it all goes downhill from there...
I used the proper tools and stuff to root it (seen it on here how to do it properly) and i unlocked the bootloader, but not the second part.
I tried relocking the bootloader again and tried to do the whole process again and it just wouldn't root.
So i stopped trying and like 4 months went past and i still haven't found the solution!
When i try to update the phone it doesn't work and says the partition is damaged!
Soooo idk what to do, I really need help because half of the system apps that we're originally on the phone are gone, even Bluetooth wont turn on as well as NFC and some other stuff :/
(BTW i have very little knowledge when it comes to phones so don't write anything to complicated, if it is complicated i'll try to do it then )
Hopefully I will solve it with you guys

The easiest way it to flash custom and go back from custom to stock if u want stock ofc . Or if u don't want unlock bootloader u Can use dload or firmware finder .

It depends. I haven't been able to find any official word from Xiaomi about it. Some get instant unlocks, some get 3-day, 7-day, 15-day, 30-day or 60-day waiting periods.
I will say that I had two devices in the waiting period. One at 15 days and the other at 30 days. I waited 15 days and unlocked one.
Then I went to check on the remaining hours of the second device and it had been reset to 30 days :/
So it may have something to do with how many phones you've unlocked in X amount of days.

S8 downgrade from Version 9

Hello, Smart people
I tried to search but couldn't find any proper solution. Is it possible to downgrade S8 running on Android 9, I want to install version 8 on it.
Thanks

i am also interested in doing this. i have had my phone for over a year, i was very careful never to download. the other day it popped up as i was taking a photo, and wham. normally i would have ripped the battery out of the back. but no such chances anymore.
the new os sucks huge. big stupid buttons, changes to the camera, the messages are pure misery.
i am on bootloader build 5. i have tried to use odin several times, only to discover this bootloader number thing on these forums.
im going to be furious if last week i was build 1.
at this point i would consider rooting the phone only out of spite to samsung for not letting me customize my phone anymore.

You can only go back to Android 8 if you have bootloader version 4. Use this code on your phone *#1234 # to know your version of bootloader.

You do not need to shut down OEM to downgrade! Respect only the bootloader version, otherwise it will brikar the cell phone, downgrade before the April patch as it is coming with bootloader version 5.

i want to fix the s8 before i stash it into storage as my backup.
can i downgrade the os to the former?
if not, if i root the phone, can i downgrade the os?

You can not because Oreo uses bootloader version 4, forcing a downgrade will turn your phone into a brick.

damn my bootloader says a bunch of numbers then 5 towards the end.

He is right, I did not realize that you use snapdragon and there is yes oreo with version 5 of bootloader so you can do Downgrade normally.

thanks so much for helping guys!
what is the oreo version i have to hunt down.
im on t-mobile.
i tried to backdown using odin, it kept giving me errors. does odin protect the phone lol?
so if i get the proper oreo os, with the boatloader 5, odin will work?
thanks again for helping me out!!!

hey, which one is the one to use? android 8 is oreo?
i tried two 7.0's, and i might have tried the earliest 8.0 on this list.
do i just go higher up, and odin will just bang it in there?
thanks so much again!

I came back to the Oreo, well done system, with fluidity and great performance, Samsung Android Pie is crap.

Version 7.0 uses bootloader version 2, and there is version of Oreo that uses version 2, 3 and 4 of bootloader, do not use these, use this here to have no problems;
