You can't. The bootloader has to be unlocked to change recoveries.
This is why you don't use toolkits, you do things without thinking and then are unable to get yourself out of sticky situations.

NEVER relock bootloader without custom recovery installed AND rooted OS running!
if you do, you're unable to change tamper bit to unlock bootloader again.
that's why i never relock my bootloader! just to be safe.

How to root 33R OTA without unlocking the bootloader?

Has anyway found a way to Root the OnePlus One without having to flash a custom recovery with the new 33R OTA?
(yes I didn't check the CM recovery)
*But after I updated to the 33R update I still had root access intact, despite gaining root by boot and not having unlocked the bootloader under 33R. The problem was I did a factory reset and obviously it reflashed the newer bootloader and I lost root access (yes stupid)
This can no longer be done 'fastboot boot twrpimgname.img' with the 33R update ;
Aren't One Plus all about give you the power so why did they go ahead and block boot custom recovery that worked before ??
This is the under 33R OTA =
C:\adb>adb reboot bootloader
C:\adb>fastboot boot openrecovery-twrp-2.7.1.1-bacon.img
downloading 'openrecovery-twrp-2.7.1.1-bacon.img'...
OKAY [ 0.402s]
booting...
FAILED (remote: Device not unlocked cannot boot)
finished. total time: 0.404s
Seems the have patched being able to boot a custom recovery without unlocking the boot loader
Yes I realized the the 'Update CM recovery' option but not after I updated to 33R (my oneplus was rooted without having to unlock the boot loader)
I did do a Nandriod backup of course before the 33R OTA.
The nandriod backup is rooted without having to unlock the bootloader via this ' fastboot boot twrpimgname.img '
Is their no way yet to boot a custom recovery without unlocking the boot loader ? Does one have to wait for a update twrp recovery to boot not flash ?
The question is: WHY?
the locked bootloader is locked because it allows only booting a signed recovery, if you use a custom-unsigned-by-manufacturer recovery there is no sense in keeping the bootloader locked.....
OnePlus knows that 90% of the users are rooting and unlocking, so there is no sense to keep it unlocked.... in case of necessity, you can relock the bootloader !!!
Anyway, you wrote in the wrong section !!!

What area is the right one, my bad.
Also asking if their is a way around the 33R to boot custom recovery
Why though?? You don't need to boot to a custom recovery. Just unlock the bootloader, it doesn't void your warranty. You have absolutely nothing to lose by doing it, and absolutely nothing to gain by leaving it locked.

Just an innocent wipe... and he only wants root.
Yeah and the right way to get root is to unlock your bootloader, install TWRP, and flash SuperSU.
Back stuff up, unlock bootloader, restore stuff. It's stupid to try to 'hack' into the world's easiest phone to root.

Please help ! Can't unlock bootloader : TWRP installed. NO OS. installed

Hi, I have a real problem with my one-week old oneplus one that I hope I can get some help with. I've spent two days trying to fix the problem with my phone and its totally baffling me.
I managed to unlock the bootloader and root the phone and install twrp and SuperSU using the Guide : https://forums.oneplus.net/threads/...oader-install-custom-recovery-and-root.64487/
I experimented flashing roms. Then I tried Oxygen but hated it. So I wanted to revert back to the factory rom and then upgrade to 11S. Since then I haven't been able to unlock the bootloader. I am using fastboot because I am running a macbook pro with Bootcamp which has a small partition and limited filespace. In fastboot, when I try to boot from recovery, it returns with
FAILED (remote: Device not unlocked cannot boot)
Whenever I try to unlock the bootloader, the oneplus reboots back into twrp before I can 'fastboot reboot'.
I've found this link http://forum.xda-developers.com/oneplus-one/development/mod-reset-unlock-tamper-bit-t2820912 this afternoon, downloaded the folder, but now have no idea how to use the script or where to put it?? I hope that this would unlock the bootloader?
Can anyone help me please??
Apologies in advance for being a NOOB. I'm upgrading from an iPhone 4S so please take pity on me !

All you need to do is download the OnePlusOne-BootUnlocker.zip file from the thread that you linked to, boot into TWRP and connect your phone to your PC, copy the zip to your phone, and flash it with TWRP, then your bootloader will be unlocked.

Nexus Stuck on Google Logo

Hello guys, I dont know whats happening with my Nexus 5 right now. Its stuck on Google logo which appears during restarting of the phone.
I have tried everything. I try to go into recovery it dosent work. I tried changing it to CWM from TWRP still it stays TWRP i get errors while flashing .bat files like (error: failure to write). Please help been stuck on this since past 72hours. Any help to resolve this issue is appreciated. Thanks :crying::crying::crying:
If the bootloader is unlocked, relock the bootloader and reboot into fastboot mode. If the bootloader unlocks itself, the internal memory is probably damaged. If the bootloader remains locked, unlock it and flash 4.4 using fastboot commands.

OEM can be locked and unlocked. But the only problem now is i cannot override the previous partitions as there is an error "failed to write" i dont understand why is this happening this is also the reason i cannot get into my recovery as when i enter recovery it gets stuck for some reason.

Let's start with the bootloader.
Boot into fastboot mode, lock the bootloader, reboot into fastboot mode. Does the bootloader stay "locked" or does it go back to say "unlocked"?

I tried the 1st step by overwriting twrp with cwm dint work. Also ADB isnt connected. I tried to but just fastboot works.
I recommend flashing stock 4.4 using fastboot commands.
Stock ROMs are here: https://developers.google.com/android/images

I tried flashing new roms it says failure to write to cache,boot,recovery everything fails!
There is no way to erase partitions as it fails!
I would say the internal memory is damaged and will require a motherboard change.

locking Bootloader again?

I unlock the bootloader to install twrp and magisk, it's possible to lock the bootloader again without problems or the phone don't boot?

Locking you bootloader while TWRP and Magisk are installed will give you a guaranteed brick. Use a Fastboot Rom to return to stock, then you can lock it
If you want to keep TWRP and root, do not lock the bootloader. As the user mentioned above, you'll brick your device.
if i flash stock rom, than is that ok to lock the bootloader ? and how to lock it ?

If you flash a full stock rom then yes. All you do is use the fastboot rom we talked about earlier, let the phone boot up (don't bother completing the setup process, just let the phone boot up), restart to bootloader, and use the following command from the command prompt on your pc:
Fastboot oem lock
It will give you a menu on your pone asking if you want to lock the bootloader. Tell it yes. It will then lock the bootloader, factory reset the phone, and then boot up normally with the bootloader locked. It's that easy.
ok thanks.one question. is that important to flash the stock rom using fastboot only ? or can i flash it using twrp ?

I did it through twrp, worked just fine. Make sure to wipe beforehand though, don't want to risk bricking your phone

Doing it with a Fastboot Rom will guarantee that things needing wiped will get wiped. When returning to full stock I will always recommend the Fastboot Rom just because of how it completely handles everything it does flawlessly. I imagine flashing a full rom in TWRP will work but I have never tried to return to stock this way
i did try stock using twrp and it was perfect
I have unlocked bootloader but in the end NOT installed TWRP or root (just wanted to test if i can live without it and still be able to install without wiping everything)
Now I just want to lock bootloader again for selling device.
Can I do so with simple fastboot command "fastboot oem lock" without bricking phone?

Use msm download tool to be sure. It will however wipe all.

You can, but if you are selling the phone I would still use a fastboot rom just to be sure everything is wiped and no data sensitive to you is being sold along with the phone.
Thanks a lot for the shared info here. This is just what I need and had been asking myself for quite some time now.??
So never lock bootloader with twrp and magisk installed.

Please help me make my phone work properly

This is the case, I have a problem with the Flash ROM, now the phone can go into fastboot, but there is no Recovery, and the phone's bootloader is locked.
You're going to have to give a bit more detail if you want help from this community.
For example:
What phone variant do you have?
What did you have on your phone when it was running properly? i.e stock android, locked bootloader, rooted etc.
What 'Flash ROM" do you mean a factory image or custom ROM?
What had been trying to do to your phone i.e upgrade from Android 9 to 10 by sideloading an image?
Had you previously unlocked the bootloader?
I'm not saying that I will ultimately be able to resolve your issues but the more info you give the more likely someone here will.
Now,my pixel 3 can not work,the bootload is locked.when I select recovery by fastboot,The phone noticed me can not find vaild operating system,the device will not start.
I used to unlock the bootloader, it is because I locked the bootloader that this situation has occurred.
Can you unlock the bootloader again in fastboot?

When I lock my devices bootload,then this devices auto wipe data, so I think oem unlock is not open.And I can not unlock bootload.
