Hi I've been having a problem with my device the OEM is set as disabled and is greyed out so I can't click and enable it. Although my bootloader is unlocked but because OEM is set as disabled, I'm unable to flash or use fastboot commands to stock flash it. However I did try using DC Phoenix to stock flash it, the files I had flashed was recovery.img, system.img and boot.img. Which it had done, however my phone it still in the same state as before, OEM is still set as disabled. I did this in the hopes that the bootloader will no longer be unlocked, that way OEM may no longer be greyed out. Am I doing something wrong? How do lock the bootloader through flashing with DC phoenix as I can't use fastboot commands.

I ran fastboot oem unlock and it rebooted like normal after wiping. Now I am trying to return to stock and anytime I attempt to flash anything it just tells me flash failed due to device not being unlocked. What's going on?
I attempted to relock it and re unlock it but that hasn't seemed to work.
I can't unlock bootloader on my OPO. I tried command: fastboot oem unlock, and fastboot mode is responded with restart to TWRP.
Also I tried a lot of things that i found forums but they did not work. I can't flash anything.
I read somewhere that I can't unlock bootloader without OS installed, but I flash Cyanogenmod 11 (not 11s, and I don't know how), and then I got this problem: https://www.youtube.com/watch?v=jlhBVj89oxU , and my bootloader is still locked.
Does anyone have solution?
I was installed with Twrp and had rooted my oneplus 3.
I unticked root access in supersu.
Booted to bootloader and typed on my pc in command prompt ,"Fastboot oem lock"
This gave a confirmation on my device,I confirmed locking.
And after that my device did not booted up.I managed to get in bootloader again as I was not even able to open the recovery and unlocked the bootloader once again by this my device booted up.
I flashed stock recovery and repeated the relocking process,this time I was able to open recovery also but no able to boot up.
I again unlocked the bootloader and installed twrp back turned my device up.
Then I unchecked oem unlocking under developer options.
Relocked the bootloader once again.
And now I am stuck at bootloader,not able to unlock it even this time as I turned off oem unlocking.
Now I can only open bootloader.
Please help!

OEM locking a bootloader on a phone that was rooted is a big mistake.
You'll need to flash stock recovery, then flash the stock ROM via adb sideload.
Can be done with this tool http://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
Thanks for reply

I can't access it as I am installed with TWRP Recovery as it is also not starting.
So I updated my FRD-L04 to the Nougat Beta, and while I was following the instructions and Flashesd the Update. For some reason I lost TWRP and cant boot into recovery, my bootloader is unlocked.....however in developer options OEM Unlock is grey out and i cant enable it.... So when ever i try to run a command through fastboot it says is not allow.... and when i try ti re-lock the bootloader i get FAILED (remote: root type is risk)... I try to roll back package from Huawei website but that also fails..... Now i dont know what to do.
I am in the same boat. Did the new beta via twrp. My usb debug was greyed out but i was able to to get it to turn on for short moments.
I have now lost twrp and now the phone wont even boot the the Android 7 beta os!
I have fastboot but when i try to fastboot flash system or cust they both fail. My bootloader is still unlocked tho.
edit: I downloaded the beta flashable zip and the update that is seperate. I took out the boot recovery cust and system from them and was able to flash them via fastboot. The phone now boots back to the android 7.0 beta. Phew!!!!!
Now to attempt downgrade to 6.0 adn get twrp back
You should look for a downgrade package
Since you have lost TWRP, I think you will have to reinstall it and root your device again.

I tried thta multiple times, but when i flash recovery it says its not allow, again i think is because i can enable oem unlock on settings
You should look for a downgrade package

Like I mention on my initial post I have already tried the downgrade package..but it does not work. I can't enable oem unlock since is grayed out ... my boot loader is unlock and I can't use the phone but NFC Bluetooth etc does not work.. I even tried to flash the downgrade package recovery and boot image through fast boot but it's not allow since I can't enable oem unlock...
I'll research a bit and see If I can find something
Hi while upgrading on Android 12 my oneplus device software is uninstalled and no i do not have any installed software and fastboot mode is locked but device is detecting in fastboot.
Is there any way to unlock bootloader or reinstall the software without fastboot?

So when you try to boot, it just goes straight to fastboot right away? If so, and bootloader is locked, you need MSM. You can try fastboot oem unlock command, but if you don't have unlock oem ticked in developer options, I don't think they're is anything else you can to

I installed the software using MSM with lock fastboot.

You installed with MSM in EDL mode? Might have to do it again. Then when it's finished boot to the system and enable developer options then tick oem unlock in the options then go to bootloader and type fastboot oem unlock. You can't install a12 with MSM afaik anyway.
