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

[Developer Verified] [TESTED] [WORKING] Meizu m3 Note Bootloader Unlock Tool

RADev Team Presents:
Bootloader Unlock Tool for Meizu m3 Note M91 (TESTED) (WORKING)​
Warning:- This tutorial is only for M3 Note (M91). Do not try it on Meizu m3 note (L91)
If you still want to try it, you're on your own as although the developer claims that it is working on Meizu m3 note (L91) it hasn't been tested
Backup all your personal data, contacts, everything to your PC/laptop as all your personal data will be lost after following this tutorial
I am not responsible for bootlooping, hard bricked, soft bricked devices, however, i will try my best to help you out of it and our team will release a hard brick fixing tool for Meizu m3 note (M91) soon. (Links will be posted here)
After you perform these steps, your phone will not have a firmware installed. You will have to manually install the firmware again.
Requirements:-
1. A mildly functioning brain
2. Ability to follow specific instructions
3. Root
4. A Meizu m3 note
5. Unlocker tool
6. A PC/laptop with ADB installed
Steps:
1. Upgrade to 6.7.9.12 daily WITH CLEAR DATA TICKED, other versions have not been tried or tested by me, I was successful in unlocking the bootloader by testing the apk on this firmware.
Link for 6.7.9.12 daily firmware:- https://download.meizu.com/Firmware.../cn_daily/20170912000320/3d65e1ba/update.zip
2. Install ADB on your system (Follow this link if you don't know the steps):- https://forum.xda-developers.com/showthread.php?t=2588979
3. Login to your Meizu account on your phone then go to Settings>Fingerprint & Security>Root Permission and enter Meizu account password. Phone will reboot and root itself.
4. Download the unlocker.apk from here and install it on the phone:- https://drive.google.com/open?id=0By0YAAxheuSKaDJ1YXJKYUJSVkk
5. Open unlocker app and grant it root permission. Click on unlock and wait till it shows unlock success and #END in the last and 2nd last line
Tip:-You can also follow the original developers on QQ (They are great guys and allowed our team to mirror, modify and post the unlock tool without wanting anything in return)
6. Now turn off the device and boot into Fastboot mode by pressing Volume Up + Power button at the same time. You will see a small dialog in the bottom corner of the phone saying 'Fastboot Mode..."
7. Connect your phone to PC, open command prompt on Windows or terminal in Linux and type
Code:
fastboot devices
. If the device ID is shown then it means that your phone is ready for flashing. If not, try installing ADB Drivers again.
8. After the device is detected in fastboot mode, type
Code:
fastboot oem unlock
Do not panic if it doesn't unlock in the first try. Keep trying. It took me a while to get it unlocked. Follow the steps on the phone when you type fastboot unlock. IT will prompt you to either press the volume up or volume down button to confirm the execution of the command you've given.
9. After the bootloader unlock is successful, power off your device.
10. Restarting the device will show you that there is no firmware installed on the phone, will wait for 5 seconds and then boot into TWRP.
11. This happened because the tool we used earlier to unlock the phone installed TWRP while unlocking the device.
12. The TWRP is quite buggy and cannot mount data and system partitions as it was ported a long time ago. To fix this, go to Wipe>Advanced Wipe in TWRP and format every partition.
13. If that doesn't work then repair file system in twrp of every partition you can. After this you'll be good to go.

[Guide] Guides for x2 Pro[Locking/unlocking bootloader, tweaks and more]

At start i want to say that I'm not responsible for your bricked devices, houses set on fire, bla bla bla and so on.
Hello​
Since I see that many users are having problems with unlocking bootloader, flashing twrp and getting properly working Magisk. So here i come.
Downloads:
Everything you need you find here, on my OneDrive.
Unlocking Bootloader
BEWARE! After unlocking bootloader your DRM widevine will change to L3.​
Steps:
- download and install Realme_x2_Pro_DeepTesting.apk,
- open app and apply for deep test,
- enable Developer Options by tapping 7 times Version in Settings > About Phone
- go to developer options and enable OEM unlock and USB debugging,
- open app once again after some time tap "Query verification status",
- If you got approved application tap "Start the in-depth test" and phone will reboot to bootloader,
- on PC, download fastboot tools from somewhere else(unless you already have it, its not on my OneDrive)
- open folder where you have your fastboot installed, hold shift and click right mouse buton and choose "open command prompt here"(or Power Shell in newer version of windows),
- connect your phone to PC, and write
Code:
fastboot flashing unlock
- now on phone select "yes"
- now your phone will reboot and erase all your data,
- now you have unlocked bootloader.
Flashing Custom Recovery
I will guide you how to flash Custom Recovery.​
Steps:
- connect phone to PC,
- on your PC in command prompt type adb reboot bootloader,
- download TWRP image from mauronofrio or OrangeFox image from thread put in your fastboot tools folder on PC,
- download vbmeta.img from my OneDrive and put in your fastboot tools folder on PC,
- type
Code:
fastboot flash recovery *******.img
- type
Code:
fastboot flash vbmeta vbmeta.img
- when flashing is done, on your phone select "Recovery Mode" with volume +/- buttons and accept with power key,
- now it will boot into TWRP
Getting properly working Magisk
For now I recommend always using Magisk Canary Debug version cause it supports realme phones(stable needs magiskfix to get out of Core only mode).​
Steps:
-download Magisk Canary zip to your phones internal storage,
- boot to Custom Recovery,
- flash magisk,
- reboot to OS.
Updating ColorOS on rooted phone via TWRP
Use Magisk Canary cause it supports realme phones(stable needs magiskfix to get out of Core only mode).
This is the only way to update ColorOS via TWRP without losing magisk or running into damaged boot/recovery image message on boot for now. ​
Steps:
- download latest Magisk Canary, vbmeta.img and latest update package(ozip) for your device(cn rom for cn device, global rom for eu/in device), if you download update via official OTA app the package is located in
Code:
/data/oppo/coloros/OTA/.otaPackage
- reboot to Custom Recovery,
- flash latest ozip through twrp recovery(don't reboot yet),
- flash vbmeta.img through Custom Recovery
- flash magisk(if flashing fail, than reboot recovery),
- reboot to system.
Locking Bootloader
Think twice after evey step you did if it's done correctly before doing next step to prevent HARD BRICKS.​
Steps:
- download right latest ozip for your device from realme site(don't cross flash device, flash global ozip on eu/in devices and cn ozip for cn devices),
- boot to Custom Recovery,
- Flash ozip and after don't do anything else, just reboot to system,
- let it boot to OS and replace Custom Recovery with stock recovery.
- (optional) boot to recovery to check if it is stock, if its stock recovery than you can lock bootloader(don't ever try to lock with Custom Recovery),
- reboot device to bootloader and through adb go with:
Code:
fastboot flashing lock
- accept locking bootloader query on phone,
- device now will reboot and perform factory reset.
F.A.Q.​
Q: Can't flash xxxxxxxx.zip(or xxxxxxx.ozip/xxxxxxx.img) in Custom Recovery cause it throws an error, what to do?
A: Reboot recovery and try again.

It is possible, but you need to use for it some other guide as I will not guide how to. It's because I don't want users to cry over their mistakes in my thread.

OK bro I'll wait then

this method is compatible with CN version? Can we install a stock Rom or EU rom after unlocking the bootloader? It's really pity for the fingerprint I think as the majority will wait a fix for this issue before doing that
Thank you for your work anyway

Nice Work
Great Guide. But at this time i'm not willing to trade fingerprint unlock for root and magisk .
Already losing the loading animation for using my good old lawnchair was disappointing can go back to coloros launcher easy though.
Maybe someone will/can find a trick for this boot unlock problem.

Thanks for your efforts!
As I don't own a X2 Pro (yet) I'd like to know how presumably it is to get a solution for the "losing fingerprint problem"?
From other phones I know, that Widevine Lv1 gets lost but I never had the problem of losing my fingerprint scanner.

I'm planning to purchase X2 Pro and it seems a flaw for me if unlocking bootloader will disable fingerprint.
Does anyone ever try not to set up fingerprint, pattern or PIN lock from the first phone setup and then directly unlocking bootloader, flash TWRP, magisk and still have locking features working?

Doesn't work. I tried it like that when I got the phone. Not logging in or setting anything on the phone, went straight to installing the unlock APK and unlocking the bootloader, still the FP issue.

Will not work cause when you unlock bootloader it formats data, so fp lock will be removed...

This method should be compatible with CN version. And for the 2nd question answer is: no, at least not yet.

Is the FP issue permenant .i mean i locked the bootloader again and all seems good now....but does that mean the realme x2 pro cannot be rooted without loosing FP???
This sucks big time ...its a shame on oppo/realme

Wow, if there is no method of getting root on this phone and not losing the FPS it would be massive setback ?

I think we're lost in translation.
Is bootloader unlocking and data wipe causing a permanent fp lock removal? Or just the ones that we have already set? If it's the 2nd case, then we can go back and set it up once again, right?

No, fingerprint sensor is disabled. Can't do anything with it on unlocked bootloader. And once you lock bootloader you get back fingerprint sensor.

Ist there any way/chance of the fingerprint issue getting fixed by xda developers (magisk module, flashable zip, whatever) or can this only by fixed by Realme itself via updating firmware respectively bootloader?

There's always a chance, be patient. I don't see a big issue with fingerprint. I got used to faceunlock. Using for a week already and I like it even more than unlocking with fingerprint.

@Jerry08
Thanks for your answer ?
It's not about not beeing patient, but rather don't have a good feeling if such a mandatory part of the phone won't work. It's just like buying a new car and not beeing able to use the remote control to lock the doors and telling people "I don't mind cause I got used to use the key instead" ?
Don't get me wrong, I'm using faceunlock very often on my device but I have a bunch of apps where I use the fingerprint scanner to log in oder authorize and I would really really miss that feature.
It's less about not beeing able to use the fingerprint scanner for a few weeks but way more about beeing able to use the fingerprint scanner in some days/weeks in connection with an unlocked bootloader (again).
As I need a new phone theese day (and Black Friday is ahead) I can't wait a few month to see, if this issue gets fixed. Otherwise I would just watch the Realme x2 pro forum and buy (or not) in a few weeks or months ?

I couldn't agree more. Most banking apps use fingerprint to bypass the password section. Also face unlock is not as secure as fingerprint.
It's a same as I would compromise on the not-so-good-photo quality over the speed and battery life of that device

@Jerry08 I did what you said, replaced the build.prop, then went to twrp, flash it, then flash your magisk canary you provided but build.prop did not get replaced. Here is the file https://drive.google.com/open?id=1CBvMuFwr84PDRZror4H9I8Std_kNNhQg My device name is RMX1991CN

Possible to get on Stock OOS11 with Root?

I just bought a carrier unlocked T-Mobile 7t pro McLaren 5g on ebay and I've spent several hours reading up on the unlocking and rooting processes for this phone.
I can't seem to figure out if it's possible to get it up and running on the stock OOS11 rom with root (and hopefully TWRP), and if so, what the entire process will be.
I've had my OnePlus 6 for several years now and have had it unlocked/rooted since I got it, so I'm fairly familiar with these sorts of things, just not on this phone specifically. Thanks

This is exactly what happened to me. I just bought unlocked T-Mobile 7t pro McLaren 5g. Coming from 6T McLaren (had 1,2,3,5 and as mentioned 6T McL). I had them all rooted and all other phones that I used before these. But reading around here I feel like I never rooted phone in my life. So much confusing information and also outdated. Not one proper post step by step how to do it. Unlocking tokens? OTA not working etc. Honestly I don't know where to start. lol

Yes, what do you need help with?

Just finished unlocking Bootloader and made steps.
Going to do root and twrp. But first I want to extract my current boot image, as I am at latest update 11.0.1.6.HD61CB

Enable USB Debugging and OEM Unlocking
On your phone go to Settings > About phone > Tap on Build number 7 times. This will enable Developer options. Now go back to Settings > System > Developer options > Enable USB debugging and OEM Unlocking. I also enable Advanced reboot.
Fastboot mode and Unlocking Bootloader
Turn the phone off. Then boot it into fastboot mode by holding volume up + and down - and power or select reboot to bootloader if advanced reboot is activated via developer options. The phone will display "fastboot" text indicating that it has successfully entered fastboot mode.
Plug the phone into your PC, then open a command prompt window on the desktop (Shift + Right Click -> Open Command Window here) and type:
fastboot devices
This command will list the connected devices. If your phones serial number shows up you are good to go and may continue. If the phone is NOT listed this indicates that your drivers are not installed correctly. In order for you to continue you must fix your drivers so that your phone is listed under fastboot devices.
If the phone has been recognized by the command above, proceed to unlocking the bootloader with the following command:
Remember this Step will WIPE EVERYTHING off the phone so Backup all your Data
type:
fastboot oem unlock
You would be greeted with a Unlock Bootloader Warning page, Hit the Vol button to select Yes and turn it Blue and Hit the Power Button to Execute the selection
Your device will reboot, show you a Secure boot warning, reboot into stock recovery and wipe all data. Once done, your phone will reboot into the OS (It will take some time to get boot – just leave it to do its thing).
Congratulations you've now successfully unlocked bootloader!
Flashing TWRP Recovery and Magisk root
https://twrp.me/oneplus/oneplus7tpro.html
fastboot flash recovery twrp-3.6.0_11-0-hotdog.img
Do not reboot to OS
Boot into TWRP Recovery
Now in TWRP, tap on Install and browse to the TWRP.zip and install it. TWRP will now be installed to both slots. TWRP is now installed. Reboot into TWRP Recovery.
Now in TWRP, tap on Install and browse to the Magisk-23.0(23000).apk and install it. Reboot to system.
Congratulations you've now successfully rooted your phone!
