OnePlus One OxygenROM- Cannot Unlock Bootloader or Root - ONE Q&A, Help & Troubleshooting

Custon Rom after Oxygen has loaded
All,
I have a OnePlusOne and I love the phone. I have had custom roms on the phone in the past and now running Oxygen and not a big fan of it. .I have now tried to Root and unlock boot loader . and it doesn't appear to be working
I have followed the directions from here:
forums.oneplus.net/threads/guide-oneplus-one-how-to-unlock-bootloader-install-custom-recovery-and-root.64487/[/url]
when I unlock the boot loader I don't think it is unlocking. I think this because it does not wipe the device
if I go thru the rest of the steps it does load the TRWP and it is rooted
I am just trying to load the Cyanogen rom or something that is clean and smooth
AM I missing something?
I can boot into TRWP
and root checker sais that I am rooted
thanks in advance

If you've had custom ROMs on the device in the past then the bootloader must have been unlocked at some point already. Did you relock it? Check the status with this fastboot command:
Code:
fastboot oem device-info

[Q] trouble returning back to stock

Hi,
I recently unlocked my bootloader and installed a custom recovery TWRP.
I am now looking to return my device to 100% stock, but I am currently experiencing a couple of issues flashing the factory image
I get the following message: "Device not unlocked cannot flash or erase"
I have also tried flash oem unlock and it just reboots the boot and returns to custom recovery
Any Idea's guys?
It would appear that your bootloader somehow got locked again. I'm on mobile right now but go into the Android development forum and find the mod tampering bit and flash that in your custom recovery and then proceed to unlock the bootloader. After that, proceed with your fastboot back to stock commands.

[Q] Nexus 5 6.0.1 (MMB29Q) not rooting & no SuperSU

I’m currently using NRT 2.1.4 and i’ve tried rooting my device a few times now and it never installs SuperSU and I can’t boot into TWRP as it shows the android laying down w/ the red exclamation, which is odd since it does go into TWRP during the process of rooting...
But I do not have TWRP installed because of the NRT process
Steps I have taken:
Unlock Bootloader
Flash stock + Unroot (Latest version MMB29Q)
Root & Custom Recovery
When I do the root step, it boots into bootloader, goes in a temporary twrp, then launches normally and says to update SuperSU binaries and check busybox, but neither SuperSU or busybox get added into my app list
It also sometimes says ADB recovery device not found on some attempts..
Is there any way for me to root my Nexus 5?
I have repeatedly flashed the stock with the newest version and still haven’t been able to root.
I have tried relocking the bootloader and unlocking it, but upon unlocking it again, it says that it's already unlocked...?
(Bootloader shows LOCK STATE - unlocked when trying to relock bootloader)
I have been able to root my Nexus 7 2013, but can't seem to get my Nexus 5 to work..
How about flashing TWRP via fastboot, then use the volume/power button to immediately boot into TWRP, and then flash supersu?
The bootloader will not relock?

Yeah, I don't know why, when I try to OEM lock and unlock it says it's already unlocked, which is odd.
But I did the TWRP via fastboot and installed SuperSU that way, thanks.
Glad it worked for your phone.
Help me to unlock bootloader and root
Hello Guys, I want to unlock the bootloader on my N5. My phone is in Android Ver 6.0.2 with Feb patch(Build Number MMB29Q). Please help me in doing so. Also i would root my device, i would prefer TWRP. Please anybody...
Boot the phone into fastboot, connect the phone to your computer, and use fastboot commands to unlock the bootloader, flash TWRP, and flash supersu for root.
Unlocking the bootloader will wipe the phone.

Can you please help me unlock OEM on Yu Yuphoria 5010A with android OS.

Hi ,
I have recently purchased a Yu Yuphoria 5010A. I thought it had cyanogen mod but found to have just Android OS.
I have searched this forum for unlocking OEM and installing recovery to install cyanogen mod. I activated allow oem unlock in developers options and then tried to unlock via fastboot . fastboot detects the device but I am unable to unlock oem as it says "remote : oem unlock not allowed " . I was able to temporary boot into cwm recovery using "fastbbot 0x2A96 boot recovery.img" but it was not able to further install the mod.
Can you help with unlock the oem and install cyanogen mod. coz all the steps mentioned in this site and others have failed.
Thank you
Hii I also bought same model and also want cynogenmod os. But I don't know if its possible to flash cynogen os . but I rooted my phone an d its working perfectly. I had same problem of can't open bootloder not allowed to open bootloader. I checked the allow to open OEM in developer option. I guess this model has already unlocked bootloader cause I just rooted it even when it said can't unlock bootloader. You can try it but download stock ROM before if anything goes wrong. And please tell me if I can flash cynogen mod is it safe

I believe that relock is impossible and but to make the device recovery to installed status of stock rom keeping with unlock bootloader.
Please see my post. May make it help or not.
When I try to burn rom with TWRP, img burns but it doesn't start and zip gives an error and cannot burn.
When I first burned custom ROM (unofficial AEX), it did not start, so when I deleted the data from TWRP, it seems that I deleted things that should not be erased, so even if I burn it from the zip file, with the error message in the image below I...

Can't Flash TWRP

Hi friends, I own one Asus Zenfone max pro m1 and I recently wanted it's bootloader to be unlocked and I tried the unofficial method but didn't worked. So I chose the official method. It wasn't a good experience because I was successful after several attempts. Don't know why... But after installing and unintalling and then reinstalling the unlock tool several times somehow I managed to unlock the bootloader. Now it's showing fastboot mode instead of csc fastboot so I believe it's bootloader is unlocked.
But as I tried to flash twrp using Bugjaeger app from another phone(since I think I'm having issues with usb 3.0 port on my lap) it's showing "Flashing not allowed in Lock state".
How can I be sure to know if my bootloader is unlocked or not? And whatif I flash rom directly(using adb/fastboot) without twrp with Corvos OS? Will O be stuck on a boot loop?
I finally came to solve my problem by trying to unlock the bootloader again and again by official method. And after 3 attempts it was succesfully unlocked (unlocked properly). I could flash twrp without any difficulties and Im on Abhix Rog version now..
