Revert back to locked state after unofficial unlock (Redmi note 3 pro/SD)

Hi All, I have unlocked the bootloader the unnofical way and i am on global 7.1.7.0(LHOMICL) with twrp and root.
I now have recieved the official sms to unlock from xiaomi.
Already i had to open the phone 3 times to get into edl mode. I really dont wont to open the phone agian.
When i try to unlock the tool answers no need to unlock. I think this is because i flashed the adapted emmc_appsboot.mbn and boot.img thru fastboot.
Do i have to change te rom to another version before i try thru edl or fastboot? What is the best procedure to official unlock now because i read a lot of bricks if they try to revert back to original state.
Can some one give me a detailed guide? Thanx in advance.
You need to flash a fully stock edl ROM on top of your current setup.
This will wipe out your hacked bootloader and throw the original (still locked) one back onto your device.
Then just unlock as usual. I did the procedure myself today already as I got my unlock notification today as well.
Ok thnx for the info. I have changed this global rom 7.1.7.0 in great extend and dont wont to lose this setup.
So can I backup my current setup with twrp with the hacked bootloader.
Flash the complete global 7.1.7.0 in edl mode. Unlock with the unlock tool.
Root the rom and install twrp.
After this can i restore the backup with the hacked bootloader with twrp?
I dont know how the unlock tool of xiaomi works, so i could leave the official bootloader in place when i do the restore with twrp and only replace system and data partition or can i flash all the parts back with twrp to keep the unlock?
Wich procedure will keep the official unlock in place or will this unlock stick always?

please give a detailed tutorial how to do it. I am now in AOSP with unofficially unlocked bootloader. How to relock it again to unlock officially?
Relock Bootloader
I see many asking how to Relock Bootloader, especially those who had unlocked unofficially.
The steps to be followed are following:
(1) Turn on USB debugging for your phone;
Go to Settings -- About Phone --> Touch 7 times on "MIUI version" to Enable Developer Options.
Now go to Settings - Additional Settings - Developer Options --> USB debugging.
Enable USB Debugging and Connect to PC.
(2) Download Fastboot ROM (file extension .tgz or .tar) from
Code:
http://en.miui.com/a-234.html
(3) Boot into EDL
adb devices (to check it's connected)
adb reboot edl
(4) Use MI Flash Tool to Flash the Fastboot ROM
PS: It is assumed that person knows how to get drivers installed for phone if not already, use ADB command as well as know MI Flash Tool basics.
@BRoy_98 @ioosis @davegrond : hope this helps.
@MrColdbird Thanks for the tip

On MiFlash, select folder of Fastboot ROM, then click on Advanced, and in fastboot script select flash_all_lock.bat. After it, close MiFlash then open it again and check in advanced if flash_all_lock.bat comes selected. If yes, close advanced box and flash ROM. Don't forget to close and open MiFlash after choose flash_all_lock.bat script, it's important step. And you can do it in Fastboot mode, don't need to go to EDL mode to flash the ROM.

warranty
does rooting redmi note 3 void warranty bcuz it has a locked bootloader and cannot root without unlocking it ????
and can we lock bootloader again for warranty claims ????
plzz help ???
ty.
Why can't we directly update the device..
Like after flashing miui ROM (7.1)then installing (8.1)....will the bootloader get locked....
?....somebody have any idea place help out
Q. Can the device be rooted without voiding warranty?
A. Yes, by unlocking the BL unofficially.
Q. Once rooted and on MiUI, can I update using Updater?
A. No! You'll lock your BL and end up in a bootloop. Instead, use the updater to download the zip file, reboot into recovery (TWRP or ZCX) flash the zip first and then the universal boot.img patched/lazy flasher and reboot to system.
I followed the method mentioned in the replies to relock the bootloader, i.e, flashed the fastboot rom in edl mode
But for some strange reason, when I entered the fastboot mode and checked whether the bootloader is locked or not by "fastboot oem device-info", it said "Device Unlocked: True"
The main problem came when I booted into the ROM; It broke all kinds of wireless connections. The wifi malfunctioned, the phone wouldn't read the SIM cards etc.
Is there a solution? Please help
Thanks

It exists if you upgrade to 6.0 Marshmallow, but is useless because we can't access bootloader or fastboot mode to flash twrp without root which is unavailable via one-click root methods.

How to downgrade from Android 7.1.1 Beta (Build NPF26F)

Hey guys, so I bought a second hand Nexus 6P, and it was running the latest android beta.
Is there anyway for me to rollback or downgrade the version, so that I can unlock boot loader, and root the device?
I'm interested in installing this rom

Any help is appreciated

I don't run the previews, so forgive me if I'm missing something here, but.. why do you need to downgrade to unlock the bootloader? Do the previews not have the "OEM Unlocking" option in developer settings? All you need to do to is enable that and then plug it in to a PC and use "fastboot flashing unlock" to unlock the bootloader. That will wipe the entire phone, including internal storage. Then just fastboot a custom recovery and install your ROM of choice.
If the previews don't have the OEM unlocking option, then log into your Gmail account on the 6P and then visit Android.com/beta and it should show your device enrolled in the beta, select unenroll. This will also wipe all data including internal storage. From there you'd go back to my first paragraph.
Read this and familiarize yourself with it and you're good to go!

Hopefully you were able to figure it out! But like you discovered, it does have an OEM unlocking option. I'm running the dev preview, and rooting is just as easy. If you haven't found any guides here's what you need to do.
Also, make sure you also turn on USB Debugging in your developer settings.
If you've already unlocked your phone, then you already have adb set up. In the case that you don't, install adb on your computer. This tool ( forum.xda-developers.com/showthread.php?t=2588979 ) is very easy to use, although there are other ways to get adb. Run it and select yes to all to install adb. You access adb through your cmd.
1) Download TWRP (custom recovery) from here - dl.twrp.me/angler/
2) Download SuperSU onto your phone from here - download.chainfire.eu/1014/SuperSU/SR5-SuperSU-v2.78-SR5-20161130091551.zip
3) Put your phone into fastboot. Power down and then hold power and volume down until fastboot pops up. Plug into your pc and then open command prompt.
4) Type " fastboot flash recovery * ". The * should be replaced with the location of the file and then the file name such as C:\Users\Kris\Desktop\twrp-3.0.2-2-angler.img
then hit enter and it should write your recovery.
5) Use your volume down button to scroll to the tab that says recovery. Hit your power button to boot into recovery.
6) You'll get a popup and go ahead and swipe to allow your system to be modified. Tap on the "Install" tab in the top left. Locate the SuperSU zip and select it. Swipe to flash it.
7) Once that's completed hit reboot and you're successfully rooted!

How to root Xperia L1?

I typed the code into my keypad and it went to system settings and it said I can't bootloader unlock this phone. Apparently I need this to grant permission for root. How do I root this particular phone? I managed to get a systemless root on my galaxy s5 by using TWRP to flash Majisk, although TWRP doesn't work for this phone. How can I actually root this phone. I would prefer to root with Majisk but honestly, I'd appreciate to know any way that I can really. Much appreciated!
if the unlock bootloader ALLOWED : is NO
then sorry sir
you cannot root this device!
There is a version of TWRP recovery for this phone which you have to flash to the boot partition, but I think in order to do this you need to have your bootloader unlocked. If your service menu says this option is disabled, then you're out of luck. :/ Sorry.
1. Go to Sony Developer site. Get bootloader unlockin code for your IMEI.
2. Dowload flashtool 9.25 with drivers.
3. In Developer menu tick allow OEM unlocking and USB debug.
I did it for my. It was not allowed to unlock bootloader first, but flashtool does it (in two steps)
i unlock the bootloader ,but i cant root this phone.
i try many ways but its faild.
plz help me to root my phone
old post I know, but did you get this rooted at all? as I have the phone (5 years now) and want to get a different OS on it to de-google it - but I'm new to it all, I have flashed firmware on other devices but never ventured into mobiles
cheers

Disable Knox on SM-T510 : Unable to unlock USB debugging, OEM Unlocking

Hello There,
I am wondering if someone could help me out here.
I have a Galaxy Tab A SM-T510 which is Knox Protected and would like to uninstall it as its is retail mode (I finished the contract and was advised to keep the tablet)
I tried to root it manually as well as by installing apks, USB debugging option is greyed out permanently and there in no option to OEM unlocking.
When I try to install TWRP Recovery or Try to manually root with Magisk's patched file, I get error in download mode as : Only official binaries are allowed (VBMeta/Recovery)
Knox is fiddling with many apps so I would like to disable it permanently.
Any ideas/suggestions/advices please?
Thanks in advance. (my first post on XDA)
