How to unlock bootloader on Oneplus Nord N100 - OnePlus Nord N100 Guides, News, & Discussion

Hello everybody
I need to know if there is a method to unlock the bootloader for an Oneplus Nord N100 but the BE2015 model (Metro PCS by T-Mobile) because I have not found out how to do it in this Forums
My smartphone is running Android 11 by an update (version 11.0.9.BE82CF).
My goal is to unlock the bootloader in order to install TWRP for a future custon ROM
Thanks to everybody and excuse my English.
Happy 2023

If I understand correctly you have to have the phone for 180(?) days and then "OEM unlock" will be available in developer settings. Then you have to request en unlock token from T-Mobile. (I don't have an american phone, I'm not 100% on the method)
You can get an unstable TWRP for this phone, but it will have very limited functionality. And custom ROMs is basically a forgotten dream on this phone.
Basically what you can do is sideload Magisk through TWRP (you have to use adb sideload command) and some people have installed GSI ROMs.

Really I bought the phone already unlocked, it has the "OEM unlock" function in the "Developer options". Because I didn't buy the phone directly from T-Mobile it's impossible to request the unlock token, so better I continue using it normally until I can buy another phone (I didn't comment but I live in Cuba...)
Thanks anyway for your answer...

I think you might be able to load a European/Global ROM through MSM tools. Then you can use OEM unlock command without token. Rummage through the N100 forums here and you can find guides.

I already searched and the ROMs are for BE2011/BE2013 models and mine is BE2015. My fear is to brick the phone in the process because it has a modified ROM especially for T-Mobile, thanks anyway

If all you want to do is unlock the bootloader I think you can just do this.
** WARNING: YOUR DATA WILL BE WIPED **
1. enable developer options -> oem unlock
2. start adb
3. adb reboot fastboot
4 fastboot oem unlock
if step 4 fails then try
5. fastboot reboot fastboot
6. fastboot oem unlock
The phone will show a screen to confirm unlocking. YOUR DATA WILL BE WIPED.
7. fastboot reboot
The phone should reboot. Unfortunately It will display an annoying message warning the bootloader is unlocked for quite a while before it boots into system from now on.
BTW: I had problems with twrp 3.5 for Nord N100 floating around these forums. Latest is twrp 3.7 which I'm still suspicious of. All of my flashing using TWRP on the N100 has resulted in bricking.
My successful flashes have been with fastboot.
I use TWRP on another phone and it works like a dream.

Hi,
In step 3, do
adb reboot bootloader
This will reboot in the ancient fastboot, not fastbootd. This is in this mode that you can unlock the bootloader.

[Q] Nexus 6 LOCKED - TWRP installed, and running??

I attempted to flash and unroot my Nexus 6 via Wugfresh's tool, and thought it was a success. I hit 'relock' and now the device is bootloader locked with no OS installed.
However, I can connect via fastboot so far, but I am not very good with it. I think I may also be able to push files, but when I attempted to flash SlimLP the device just reset.
TWRP is still present on the device, but I cannot unlock my bootloader without getting a ROM on there... So I am stuck...
I need to mail this phone back in tomorrow for cracked screen, so I am hoping someone can help me. Thank you.

First check here... http://forum.xda-developers.com/nexus-6/general/how-to-nexus-6-one-beginners-guide-t2948481
Get the sdk tools and once set up, see if you can do adb devices and have the phone show up on the PC, if so, do adb push (name of rom file) then boot to twrp and install. If that doesn't work, check the same page above (since you don't have an OS not sure what would happen) try the unlock instructions for fastboot ( I would wait for someone else to comment before trying this). You might want to message this user http://forum.xda-developers.com/member.php?u=2872010 rootSU and see if he can give guidance, he has lots of experience.
Locked Bootloader
I still can't seem to get past the fact that my bootloader is locked...
Thanks though.

Try this: Reboot to bootloader, select recovery mode, enter TWRP, mount MTP and push/sideload and flash a flashable image from here http://forum.xda-developers.com/nexu...tboot-t3066052.
Flashing
Hey, thanks for the tip.
The link you sent was dead, and can you help me understand the commands for flashing in ADB with a locked bootloader?

Sorry my bad, here it is http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052.
Follow the instructions as i posted, place the download rom in the /android-sdk/platform-tools/ folder and boot in bootloader and select recovery, select adb sideload there and type in cmd: adb sideload name.zip.
Unlocked Bootloader
The thread says they are for unlocked bootloader only.
I have TWRP installed, but for some reason at one point my bootloader was relocked.
So now I have No OS to 'enable oem unlock' to unlock my bootloader.
This is my issue.

It worked for other users, but hey if you have a better option try that.
I don't understand, what do you mean it worked for other users? The thread specifically states the bootloader has to be unlocked, and unfortunately I do not have an unlocked bootloader.
So I cannot fix this issue unless I either get a rom to flash with a locked bootloader, or somehow force unlock the bootloader

Look in this thread http://forum.xda-developers.com/nex...bootloader-t3116744/post60931367#post60931367, he had the same problem as you (locked bootloader). I`m not a jehova witness trying to convince you to swap sides, i`am trying to help you here.
Thanks
I see, I was able to adb push /sdcard/. a factory image to get back in with a locked bootloader, thank you.

Purchased Used P20 Pro with unlocked bootloader

Hi all,
I've purchased a used P20 Pro from a friend which has an unlocked bootloader and has been previously rooted. I normally keep my phones stock so I want to lock relock the bootloader (I have the code) but despite trying to follow various guides I have been unsuccessful.
Would anyone be able to guide me through the process of relocking the bootloader please?
The main reason I like to keep stock is manufacture updates etc and I don't have the knowledge to maintain a rooted phone.

I don't believe that an unlocked bootloader will prevent you from getting updates. As far as I know the only difference is the warning you get when you boot that "you can't trust the phone."
IF YOU BRICK YOUR PHONE IT'S YOUR RESPONSIBILITY
Don't know if there is another way but of you have fastboot and adb you can do it:
1. Make sure developer options are enabled
2. Connect your phone to the computer using USB cable.
3. Open a command window and type 'adb boot bootloader'
4. Once the device has booted into the bootloader mode type 'fastboot oem lock'
This WILL ERASE all your user data and you will have to configure everything from scratch. You will need the unlock code if you ever want to unlock it again so make sure you don't loose it.

can we unlock the bootloader

It ws esy unlocking the bl in g5s+ , what about the z3 play, wife surprised me with this phone, im liking it already, but would like to unlock the bl and eve tually gain root/custom recovery ?
Anyone?
Depends on the model you have specifically, certain ones cant be unlocked such as amazon version. But the steps are the same as all other android phone bootloader unlocks, Steps can be found on motorola website:
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
The basics consist of:
enable developer mode
enable "OEM Unlock" in developer settings
fastboot into phones bootloader and run OEM unlock commands
copy unlock code from phone that you get using oem unlocking commands into motorola website
receive email from motorola with unlock "password"
enter password into adb terminal
phone will be wiped and bootloader unlocked
Thats what i thought, i went there just to see , looks the same as for my G5S+ , ill likely do this. Is there guide somewhere on instally magisk as im outdated ( an old chainfire guy) just need some hints , doesnt look like twrp works , what about clockwork mod? Thats fine as well, , any good roms? Think 9 is comming?
Magisk root is straight forward. You can either get a working boot.img for your device from a firmware package and patch/flash it yourself. Or boot NOT flash the twrp images from the twrp website and install the magisk zip that way. The twrp for this device hasn't been compiled for flashing. It boots but flashing it to your device will boot loop it. No custom ROMs that I know of but I'm just using stock with magisk and it's fine once you have root to delete the bloat ware apps and install tweaks from magisk.

Pixel 5 Android 12 Developer Preview 3 OTA Sideload failed at 94% and now it says "Can't find valid operating system. The device will not start."

I tried to install Android 12 Developer Preview 3 on my Pixel 5 via OTA Sideload but it failed at 94% with the message 'adb: failed to read command: No error' on cmd and 'Install from ADB completed with status 0' on phone.
After this when I try to boot, I get the following message: 'Can't find valid operating system. The device will not start.' (attached image)
I'm able to access the bootloader but when I tried going into recovery mode through the bootloader, it shows the same message: 'Can't find valid operating system. The device will not start.'
Seems like the recovery is corrupted as well.
Unfortunately I had not enabled OEM unlocking in the developer options before trying to install the Developer Preview, which is now not letting me unlock the bootloader.
Please help me fix the issue or help me find a way to unlock the bootloader without enabling OEM unlock.
Thanks in advance.
I had the same thing happen to me just now. Have you managed to figure anything out?
Nothing from my side, since bootloader is locked I can't flash the system image and I can't unlock bootloader because my OEM unlock is turned off in developer settings and the Recovery and Rescue mode are also corrupted.
I contacted Google support and their only solution was to bring it in for service as my device is still under warranty.
I'm in the same boat here with a Pixel 4a 5G. Got to 94%.
First time I've experienced an issue while sideloading. . .
Contacted google support and they are shipping me a refurbed replacement... disappointed, to say the least.
Not sure what to make of this, it's developer preview and now beta. Issues will possibly occur and it warns you of such.
**Possible Fix**
I would believe this might be due to the boot_a & boot_b when trying other custom ROMs or OTA updates.
I used the fastboot/ADB files from the lineageOS ROM page and used the command: fastboot flashing unlock
to unlock the bootloader again, this then allowed me to go back into the rescue mode and use googles online image reinstall and got me back onto the stock ROM. Hope this helps some people

As an additional this let me get my phone back to loading the custom ROM I was on, to then reenable debugging mode, I then rebooted back into fastboot mode and used Googles online factory restore mode to flash stock ROM back on and I was back up and running

As I had mentioned earlier: I had NOT enabled OEM unlocking in the developer options before trying to install the Developer Preview.
So this method does not work for me. It will be helpful if I can find a way to force unlock the bootloader somehow.
Thank you for your reply. Hope your method helps someone else resolve their issue.

This might not work but have you tried plugging the phone into the computer using the pixel online factory recovery and tried the first step of the process which is a prompt to unlock the boatloader?

I'm going to state what should be obvious here - you should not attempt to use pre-release firmware with a locked bootloader, because you will ne severely limited on what you can do to recover if something goes wrong.
Unlocking the bootloader is not possible if OEM Unlocking is not enabled.

What exactly are you referring to? The Android Flash Tool requires an unlocked bootloader to start with, and does not unlock the bootloader itself.

Are you not aware of the Google online tool for their Pixel phones? https://pixelrepair.withgoogle.com/carrier_selection
This has additional flashing options within the 'online' version of fastboot/adb, and found that when trying locally downloaded adb/fastboot it didnt work. But when using the online version it allowed me to unlock the phones boatloader.

I am aware. However, this tool does not function like adb and is not meant for flashing factory images like the Android Flash Tool is. The Pixel Repair Tool works specifically from Rescue Mode.

Unlocking bootloader FAIL

Hey guys,
I am trying to unlock my bootloader on my OP 7 pro Global version. i am currently running android 12 and hate it so much i am trying to downgrade back to 11.
In order to do this i need to unlock my bootloader and flash the old os... but I keep getting this weird error.
When i run command "fastboot oem unlock" i receive -
FAILED (remote: 'Device cannot be unlocked for technical reason.')
fastboot: error: Command failed
When i run "fastboot devices" i can see my device.
under developer setting i have all ready toggled allow oem unlock...
nothing seems to get around this issue and i am currently stuck and have no idea what else to try.
The MSM Tool should help you. Worked for me. I converted my T-Mobile variant, to Global using it. Follow the guide, and the MSM tool will flash your phone back to stock, with bootloader locked once again.
Edit: I should note, the tool will wipe your phone, so backup obviously.
