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

[Help!] EDL Doesn't work

Hi everyone, i cant enter to EDL mode, i need it because my stock rom is unstable(All start with OTA update), after update it show me "unfortunately android.... has stopped " every 3-5 seconds. EDL works fine yesterday and i try to install fastboot rom, but since MiFlash get error when i install fastboot rom i cant reboot in EDL. Hope you can help me.
note: I try reboot trough fastboot and do same thing as the video.
youtube. com/watch?v=gPh1yE3or8g&feature=youtu. be
(Sorry for the video post, but i cant find something like this case in web and i really need help)

You can try load in fastboot, connect to pc and run edl.cmd from archive.
www28.zippyshare.com/v/sKankJGd/file.html

go to fastboot and type "Fastboot oem edl" then enter and you will find the device got into the EDL mode

Unlock your bootloader and flash a custom recovery is the best way

I have the same problem
Hi! I have the same problem! I can´t get to EDL mode, also I cant update with MiFlash anymore.
I´ve been searching for over a week for a solution but I can´t fix the phone.
I´ve done the following.
1. Bought the Redmi 3S phone from Gearbest, came with a rom with adware, I was unable to update the rom from the updater.
2. I downloaded an Official Fastboot ROM from the XIaomi website, then updated to latest version MIUI Official TeamVersion Stable ROM: V8.1.1.0.MALMIDI (MIUI8), without unlocking bootloader.
3. After succesfully updating the phone, Android starts but then I get a continuos error message and I cant do anything. Now I can only get to Fastboot Mode (EDL does not work anymore, even using Fastboot EDL mode). If I try to flash it again with Mi Flash I get Flash tz error.
4. I applied for unlocking, received the message after 48 hours but I am stuck on 50% with the error -current account is different from account info on the device xiaomi-
5. I am unable to update the firmware using fastboot mode, recovery mode or EDL mode, Unable to unlock the bootloader. Already tried several methods with no results.
Please help!
Thank you very much.

If your issue is just to go to EDL mode and get back Qualcomm 9008 port com why not to try the "cable trick" found for the redmi note3.
https://xiaomi.eu/community/threads...-edl-no-fastboot-no-logo-no-led-solved.34113/
See post n°22 and it is no risk to try it. The cable would be reusable.
You have also many other posts on the subject, just goole it.

Here's a really easy way to make a deep flash cable http://forum.xda-developers.com/xiaomi-redmi-3s/help/help-bricked-phone-t3510277/post70029683#post70029683

As said, the device does not leave the screen of the leeco, does not start in recovery and fastboot mode. So there is no way I can restore using TWRP. The device is recognized only by the qualcom tool. I need a guide on how to use it. Anyway, thank you for your time.

This method is very important for those with locked bootloader. Can anyone else confirm that it works ??

i can confirm that it enters in edl mode..chk this

doesn't work

Need confirmation from more users, whether this method works or not.
Thank you in advance.

Yes it work if you have unlock bootloader.

if you don't feel like downloading, the command to get into EDL is:
fastboot oem edl

Will it work on Snapdragon variant without unlocking bootloader

not working on 2017 edition... must open the backdoor case to do edl

Have you tried it or just saying?

He wrote that : "tested by me'', not sure tho.

confirm not working on device with lock bootloader

This doesn't work unless your bootloader is unlocked
If anyone is thinking they can root their device via this method, it's not gonna happen. cuz edl in 4X requires unlocked bootloaders or sorting tow points on motherboard. some people says they can make edl cable for 4X but I've not tested it by myself

Is there any way to flash to china rom because my phone is issued by china
thanks pro

do you try to use mi flash and use the fastboot method?, you can enter to fastboot?

Hello,
Can you enter in fastboot mode?
Try this fastboot version (attached), to enter in EDL Mode ("fastboot reboot-edl" or "Reboot.bat"), and flash again your original rom with MiFlash.
In EDL Mode you need "Qualcomm QDLoader HS-USB Driver"
https://androidfilebox.com/tool/qualcomm-qdloader-hs-usb-driver-32-bit-64-bit
If you can not enter "EDL Mode" in the previous way, you should try test point to enter EDL.
https://www.youtube.com/watch?v=XzknDcBovWw
If you can install your original ROM in EDL mode, you may have to install the ROM again in fastboot mode.
In the MiA2 this was done, first install the original ROM in EDL mode and then when you could start Android, enable USB debugging and reinstall the original ROM, but this time in fastboot mode.
Regards!!

im in same situation my phone is on 10.3.5 his box its in chinise, i try with test pointe but in mi flash tools say unauthorized for this opperation, in qfile or miraclee thender flash success but phone alway dead
