*Unlocking bootloader will remove all your data!*
I'm using Windows 7, and that's the steps i did. (it should be simmilar for other systems too)
Getting code:
Code will look simmilar to this: DB1ED223C5537BA756FB0671E425D650
Method 1 (no root):
Go to
https://passwordsgenerator.net/md5-hash-generator/ copy paste serial number and click generate. Then you should see code in "MD5 Hash of your string". You can also go to simmilar md5 hash generator sites, but this site automatically converts small letters to big letters.
Method 2 (root):
Okay, this is new method that is much easier and you don't need to send IMEI and wait for @the_laser to give you code. Go to terminal emulator, type su and execute it. Then type this and execute it:

Actually the command is
echo -n NE1GAM4770133666 |md5sum |tr [:lower:] [:upper:]
If you don't use the -n flag, the newline character is also passed and you get a different result

Unlocking bootloader:
Download platform-tools which activates adb and fastboot commands (first you need Nokia 3 driver installed if you didn't)
Nokia 3 driver: http://www.devfiles.co/download/3iK0k7Sv/Nokia_3_USB_Drivers.zip
platform-tools Windows: http://www.devfiles.co/download/KtLsN6fX/platform-tools-latest-windows.zip
platform-tools Mac: http://www.devfiles.co/download/OkrfluP0/platform-tools-latest-darwin.zip
platform-tools Linux: http://www.devfiles.co/download/vk5DudZX/platform-tools-latest-linux.zip
Enable usb debugging in Developer options before running adb. To get Developer options, go to settings, about phone and press build number 7 times. Also enable OEM unlock.
Now Connect phone to computer via usb and enable usb file transfer, run cmd as administrator, then type this command which runs adb:
chdir C:/Users/John/Desktop/platform-tools (this is just a example, you need to type your own location of platform-tools)
then type this command to check is your device connected to adb, it will show serial number of your device, if it hangs at waiting device, then you need to reinstall drivers (if you're doing this first time, then it will ask to allow usb debugging on your computer, just tick always allow from this computer and click OK)
adb devices
then type this command to reboot to recovery (you can boot to recovery by holding power on + volume up (only with usb connected) if this command doesn't works)
adb reboot recovery
when booted to recovery, choose reboot to bootloader option with volume sliders (this will boot to fastboot)
when booted to fastboot, it will show text 'FASTBOOT MODE' in down-left corner
now type this command to check is your device connected properly to fastboot.
fastboot devices
if it show characters like 0123456789ABCDEF or simmilar then it is connected properly, if it hangs on waiting device, then you need to reinstall drivers like mentioned above.
Android Nougat (7.0 & 7.1.1):
Now type these commands to unlock bootloader
fastboot.exe -i 0x2e04 oem key (type your key after oem key)
fastboot.exe -i 0x2e04 oem unlock
then press volume up, when asked
Android Oreo (8.0 & 8.1):
First download NE1-0-215H.lk.bin:
https://my.pcloud.com/publink/show?code=XZaLMs7ZclQ2wvKwSb0ofUraMmrsiHh6uk1X
Now type these commands to unlock bootloader
fastboot oem dm-verity <your_unlock_key>
fastboot flash lk NE1-0-215H.lk.bin
fastboot reboot-bootloader
Proceed your unlock procedure.
If you have problem on flashing the lk partition, you can use MTK Smart Phone Flash Tool to flash lk partition manually.
After lk partition flashed, you may encounter "Red State" when booting the phone. Ignore that and boot your phone to Fastboot mode directly with OST LA.
That is it, i tried to explain for you to understand everything i did to unlock bootloader.

way to enter recovery without adb -
power off phone
press and hold volume up + power on buttons, insert cable immediately
countdown will start on phone, hold both keys until countdown ends, then IMMEDIATELY release power on key, still holding volume up
you will enter recovery shortly
after installing TWRP it is very important - DO NOT allow /system modification until supersu package installation ! ( or you will require reflashing phone with OST )
another note - can't enter recovery by combination volume-up + power button, if phone not connected to computer
one man reported, that even he successfully flashed TWRP image with "fastboot flash recovery <twrp image>", he still got original recovery.
workaround is to use "fastboot boot <twrp image>" - as we need to have USB cable connected to enter TWRP recovery anyway, not big problem.

Someone told me that if you flashed twrp, that it automatically removes data encryption. Is that true?
EDIT: i find out that is not true, it asks for some password to decrypt data, but the problem is that idk what is the password
DON'T install xposed! It bootlops.
EDIT: My fault, it actually work but you need to wait more than usual to boot.
That is great guys.
Do we have a working recovery yet?

I use this twrp https://1drv.ms/u/s!AsmTb5aqoY12mDZqDZbPOp47QVMV
I have stock recovery, but I use fastboot command 'fastboot boot recoveryname.img' when I need TWRP, and that's awesome because I don't lose stock recovery which is useful to flash OTAs and Nokia zips. I flashed SuperSu 2.79 just fine, but expect some crashes like software update, device monitor crash, but actually everything works, software update works just fine.

TWRP can't handle Android 7.x default disk encryption, just press "cancel" and we need to use sdcard as storage for backups and packages because of this

link for twrp
https://1drv.ms/u/s!AsmTb5aqoY12mDZqDZbPOp47QVMV
when downloaded, copy twrp to folder platform-tools and rename it to recovery.img
reboot to fastboot, then type this command:
fastboot flash recovery recovery.img
then reboot, fastboot reboot
if it didn't worked, use this command just to boot to twrp (you need to do this everytime when you are connected to PC)
fastboot boot recovery.img
To install root, first disable system modification on twrp then flash this zip for root.
This is not the latest version of SuperSU, but newest releases have some problems and crashes. (at least for me). This is last version that works for me.
That is it.
Thank you!
Is it possible after unlocking, installing twrp and root, to return the device to factory settings for ota updates? If so, how?

Click to collapse
on twrp, there is a option wipe, click on it, then you will see option swipe to factory reset. then wait and reboot.
And you can now enable system modification if you want (it is recommended to enable it because some zips fails to flash because this option is disabled)

Hello. I can't get my phone rooted in any way.
I want to Root so I can use TWRP app to flash TWRP recovery .img, and after that I can boot into TWRP recovery and flash new ROM. Correct????
What I've tried so far. OppoTools 1.6.5 = One key root gets hard stuck on Oppo logo at start-up and then I have to flash Coloros ROM again from recovery. Also KingRoot says app not installed. On windows version of KingRoot it gets to some percentage and then it Fails.
I have downloaded "unlocked bootloader" Coloros from this forum that was mentioned before ( Dropbox link )
I have also tried two different ColorOs versions.
I have installed 15sec ADB installer.
I plug my phone into PC and run CMD.
I type adb devices into command prompt and it detects my R7 plus.
then I try to command " adb reboot bootloader "
Phone restarts normally and doesnt go to bootloader. Tell me if im stupid, but isn't Bootloader different than Recovery? Because I can get to recovery command "adb reboot recovery"
I tried some weird button combination Vol+ Vol- + Power and phone semibricked for awhile and PC didnt even react USB driver correctly and almost waved the white flag on this case.
I've enabled USB-debuggin and OEM unlock from devices dev-options.
When I to type command "fastboot oem unlock" on command prompt is says Waiting for device. Nothing pops-up on device and nothing happens.
So now Im stuck on situation that my phone doesnt launch into bootloader where presumably "fastboot oem unlock" would work?
If you have flashed the version of Color OS that has bootloader enabled, you should simply need to go into the settings, enable USB debugging and OEM unlocking, then shutdown the phone before holding the power and volume+ buttons and waiting the ADB bootloader screen. After that, just plug it into the computer and follow the guide on flashing twrp with ADB.
Hi, I am writing this guide because many people followed other guides in the forum and lost their data. This is the proper way of unlocking the bootloader without losing your data.
0 - Read the whole guide before proceeding and proceed at your own risk!
1 - Make sure you have adb and fastboot installed on your device,
For Windows follow this guide (I suggest installing it system-wide, so that you can execute commands from every directory on your PC): https://forum.xda-developers.com/showthread.php?t=2588979
For MacOS and Linux : https://www.xda-developers.com/install-adb-windows-macos-linux/
2 - After the required tools are installed go to Settings -> About Phone on your phone and keep tapping on build number until a toast notification tells you that the developer settings are enabled.
3 - Go to Settings -> System -> Developer Settings and enable OEM unlocking option.
4 - Turn off the phone and when it's fully off, hold power + vol down button to boot into fastboot mode. When you've done this step successfully, you will see a blue FASTBOOT text on the screen with a bunny scrambling the internals of Android.
5 - Connect your phone to your PC and open a CLI/terminal/PowerShell window and type this but do NOT hit enter :
Code:
fastboot oem unlock
when you are ready to execute the command, start pressing only vol down button and then hit enter, HOLD vol down until the phone boots into fastboot mode again. This basically tricks the phone to boot into Fastboot mode instead of erase mode. To make sure the phone doesn't boot into erase mode on the next boot you need to do the following:
6 - While in fastboot mode type this into the CLI/terminal/PowerShell window but do NOT hit enter :
Code:
fastboot reboot
when you are ready to execute the command, start pressing only vol down button and then hit enter, HOLD vol down until the phone boots into fastboot mode again.
7 - Now you are ready to boot into your system. Either boot by holding power button or typing
Code:
fastboot reboot
into the terminal and hitting enter.
By rebooting twice, you make sure the phone doesn't boot into erase mode. If you flash the stock ROM beforehand and setup your device (login to Play Store), your device will still be Play Store certified by this method. But if you unlock the bootloader and the phone erases its storage, you won't be able to download apps like Netflix, because your device will not be certified by Play Store, this is because the Play Store checks for unlocked bootloaders. But by making it check the certification while it's locked and then unlocking the bootloader, you can make this issue go away. Feel free to ask for more proper guides for dummies, if you need. I have bricked my device many times and learnt by trial and error, so I'd be happy to make you avoid those same mistakes. Cheers.

It is not necessary, but a preventative measure. I've had instances where I hadn't rebooted twice and the phone booted into erase mode. This is a guide for people who want to make sure they won't lose data.
Another tip:
If you're with stock everything and don't want to loose data, do not boot into recovery mode (power + vol+) as it sometimes try to wipe data without any confirmation. Did happened here once, back in March 2019, but thankfully my pictures and most data are stored in MicroSD card.

Can confirm, if your bootloader is unlocked and you don't have TWRP installed, booting into recovery mode will wipe the device.

It shouldn't ask you to unlock phone or not in fastboot mode, as what I did unlocked mine for months ago. It should return you to fastboot mode in a flash (a fraction of seconds) and manually restart your phone by holding up power button until you'll see unlocked warning and AndroidOne logo.
If it is, try to select "unlock", but your data may wipe afterwards.

You have another device. This is for Mi A2 Lite, not Mi A2. And on top of that, it works for Android Pie. I don't know for stock Android 10 since we (Mi A2 Lite users) don't have it yet (as of my writing).

You can unlock with the same method. But I believe you will flash a zip from TWRP to fix SIM cards and that will break your phone if you lock the bootloader. So after fixing the SIM cards, you need to leave the phone unlocked, otherwise phone will be bricked. If you want to get rid of the ugly splash screen, you can flash a custom splash you can find in the forum.

Wowwww! Thank you very much, time ago I've unlocked the bootloader without losing any data
That's a very good solution
Is there any successful way to relock bootloader, i wanna unlock the bootloader only if i can relock, because i need to sell it later. It's an EU device, i think as it's belongs to Pakistan.
Incase you did not get an answer, yes!
So in order to lock BL, you just have to repeat the same steps as unlocking but a little differently.
I'm new here so cant put links here, but i'll try to make it simple
steps:
1. Download the unlock tool again to apply to exit the in-depth test.
2. Click “Apply to exit in-depth test”. Your phone will reboot automatically, and you will enter the Fastboot mode.
3.In the Fastboot mode, go to the minimal adb and fastboot folder and use the engineering command below on your PC to re-lock the bootloader.
– Enter the command: adb reboot bootloader
– Press “Enter” on your keyboard
– Enter the command: fastboot flashing lock
– Press “Enter” on your keyboard
4.Press the Volume Up button to select the “Lock bootloader” option
5.Then enter command “fastboot reboot”. The phone will reboot and exit the in-depth test mode. All user data on the phone will be erased – I recommend you perform a data backup prior to applying in in-depth app.
(Also please take backups of boot, recovery and all the essential files via twrp [or whatever recovery software you'd be using] )
Good luck :good:

Hi,
Thank you for your post.
I need to bring back my RealMe 5 Pro to original settings it was when I bought it.
I unlocked its bootloader + I rooted it.
Now I want to revert it all back.
How can I do that safely?
Flashing stock firmware directly on it?

This part of the guide is part of the tutorial made by @Arin59 at https://forum.xda-developers.com/nokia-3/how-to/method-to-unlock-bootloader-nokia-3-pie-t4012285
First of all convert your serial number (should look like NE1*************) to MD5 Hash and enable OEM Unlock in developer options.
Then reboot to fastboot and type
Code:
fastboot oem key {HASH}
then type
Code:
fastboot flashing unlock
.
To reboot to Android, run fastboot reboot.
Installing TWRP
Code:
This will delete your user data, but it should be already deleted.
You can use any TWRP image made for this device but I had the most success with https://forum.xda-developers.com/nokia-3/development/twrp-teamwin-recovery-nokia-3-t3762512 .
Flash your TWRP Image chosen with
Code:
fastboot flash recovery your-recovery-image.img
and then reboot to recovery.
In TWRP go to Wipe and then Format Data and type yes.
Install Magisk
Install Magisk normally.
< waiting for device >
I put the phone in fastboot mode and ran fastboot with the oem key md5 hash command but it just said "< waiting for device >". I think it might be because I forgot to install the Nokia 3 USB drivers. I'm using a linux computer, do I need to find OS specific drivers?
edit: And now my phone is stuck in fastboot mode and for some reason will not shutdown no matter how long I hold down the power button for.

If you're using a linux computer, you should try running the command with sudo.
If it doesn't work, try with another cable (or computer if it doesn't work) and try again.

Thanks. I've since got it working. For some reason I had to use the -i argument (the interface argument) along with the code for the device (0x2e04) "fastboot -i 0x2e04 <command>".
However, I've recently bypassed the "NO COMMAND" screen and gained access to TWRP custom recovery but in trying to shut down the phone, it shuts down fine but only boots up in fastboot mode. Even using the fastboot reboot command from adb tools boots it up in fastboot mode. This is a problem as I need to boot it in its normal mode so I can download the magisk.zip file required for installing magisk but I seem to be unable to do so.

Try holding volume up and down at the same time while holding the power button.

Thanks, it worked.
Though I tried wiping, but it didn't solve the booting issue. Unsure how to proceed at this point. I feel like I've tried everything. Actually, I just checked my /boot folder and it's empty...is that why it's always booting into fastboot?
I tried using adb to sideload the magisk.zip file but then the phone rebooted into stock recovery??
Any and all guides on this say to download the magisk.apk either into the SD card or internal storage, but I don't have a micro SD card and I can't access the normal mode of the phone to download anything.
What can I do?
I've flashed TWRP successfully but forgot to download the magisk.apk. Now whenever I boot up my phone, it boots into stock recovery mode automatically, even if I tell TWRP to reboot into system it reboots into Stock Android recovery. I can still access TWRP by holding down the up + power buttons on boot though, but I can't access the normal mode of the phone anymore.
I tried using TWRP's sideload feature with ADB tools to sideload Magisk.zip and it said it succeeded but in using TWRP's install feature to find the zip file, it wasn't in /sideload/ or /storage/ as both were empty.
How can I temporarily restore normal functionality so I can simply download the Magisk manager.apk?
