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.

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 fix It. The solution is easy but in anyway you need wipe your device
The steps are below
1 switch your phone in bootloader mode
2 with fastboot enable OEM lock , after lock the phone will be wipe
3 wait boot and configuration
4 enable develop mode e now you can disable OEM protection (FRP)
5 now switch your phone in bootloader mode and with fastboot unlock OEM
6 after wipe your phone will be with bootloader unlock and Frp unlock
Good luck

Please help me...oem unlock is disabled

Hi friends
My phone is frd-l09c10b501 in android oreo
But oem unlock is disabled and i can't flash twrp recovery
Because oem unlock is locked and can't enable it
Please help me ??
Hello,
Greyed out OEM Unlock option can means "already unlocked" or simply not available for this region (firmware region?) and/or network carrier...
Check this, it can help: How to fix OEM Unlock greyed out or OEM Unlock disabled problem
Do not forget that your need to unlock your bootloader first via fastboot unlock command (using the unlock code for your device).
Then flashing TWRP on Oreo is not the same command as previous android versions AND you need TWRP "EMUI 8.0" compatible version.
New fastboot command:
Code:
fastboot flash recovery_ramdisk twrp-filename.img
And below, I give you 3 TWRP versions that shoud work for Honor 8 EMUI 8.0 (Oreo) devices:
1) Official latest TWRP version: twrp-3.2.2-0-frd.img
2) Previous version (found in "Huawei Multi-Tool by Team MT" v8): FRD_TWRP_3.2.0_EMUI8.img
3) Modded TWRP version (found in "Huawei Multi-Tool by Team MT" v8): FRD_TWRP_S_mak_KV_v2_EMUI8.img

apparently the Russian firmware does not allow the unlock of the OEM. I think maybe there are no solutions. I do not know how to make a rebrand with oem and boot stuck.

Before frp was unlock but when i doing factory reset again frp and oem both lock
The Russian variant allows unlocking, you can't block this. It's illegal, even there. You need to unlock your bootloader. It's that simple. I do not care if you did it before, you need to do it again since you flashed firmware.
