Please help ! Can't unlock bootloader : TWRP installed. NO OS. installed - ONE Q&A, Help & Troubleshooting

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.

I dun goofed, messed up my OPO.

Okay so, first things first:
I can boot into both Recovery AND Fastboot
ADB Sideload does NOT work in my TWRP
Tampering bit is true and bootloader unlocked is false
My problem now is;
I need to unlock my bootloader because right now, my phone has no OS. I can't unlock it though because neither fastboot oem unlock works nor through the OPO Toolbox/Toolkit.
I can't flash anything to it right now and I need to find a way to unlock my bootloader, whenever I try to unlock it, it reboots to TWRP.
Please help. <3
adb push yourrom.zip /sdcard
Then just pick the ROM you just copied onto your phone storage using the above command in TWRP and you should be fine.
If that doesn't do the job then you can always use the brick recovery download tool.

[Help!] FRD-L04 Bootloader locked, FRP Locked, No Recovery, SOT?

so i unlocked, rooted and installed LOS on one of my classmates honor 8 a few months ago. for whatever reason he decided he wanted to go back to stock and asked me help. due to work and school i was unable to help so he came on to xda to find help.
he ended up using a guide and............... well, its all f*cked!! i dont know how but his phone is not only bootloader locked but also FRP locked.
to make things worse, the phone wont boot and it has no recovery. i have tried the vol+ and power, vol+- and power but non work. i am able to get into fastboot. i have thought of maybe sending the phone in to maybe huawei us but the phone came from ebay.
the phone was a damaged ebay win that was repaired by me. it worked great but i dont know if its possible to send to huawei for repair. anyway, i would appreciate any and all help.
You might need to reset with the /sdcard/ dload method. Check out the other forums for instructions.

It's highly unlikely that you're SOL, if you can get into the bootloader then you can flash the stock recovery. If you can flash the stock recovery, you can flash a rollback package to completely restore everything to stock.
So long as you have a working fastboot, you're fine.

ah, the thing is..... both the bootloader and FRP are locked. as i mentioned, he wanted to return to stock and followed a guide here. he doesnt remember what exactly he did as it was almost a month ago but it ended relocking the bootloader and FRP. i really feel horrible for not helping him which is why im desperate to get this working. i might just end up giving him mine.

so i tried and nothing, i get to the blue splash screen and the phone just reboots. i keep trying to unlock the bootloader but i get the same error as i posted above. shouldnt i be able to unlock the bootloader? im thinking that i have some kind of driver problem.
my pc is pretty much dead so im using my laptop and im not sure i have it set up correctly. anyway, i know oem unlock is required to unlock bootloader but is there anyway i can unlock straight from fastboot?
Try a 'fastboot oem relock' with the unlock code, then after the reboot, try unlocking again.

Honor 8 FRD-L09 Can't flash TWRP FAILED (remote not allowed)

Hi, I'm trying to root my Honor 8 device and install TWRP. However when I try to flash the TWRP file in ADB, I get this error message:
FAILED(remote not allowed). I have tried different versions of TWRP, the latest one and the one thats for Honor 8 on their site. I have unlocked bootloader. I don't understand what's happening. Can someone please explain this?
It's my first time rooting a device manually, so i dont know much. If you are able to, please refer to things in an easy manner.
Thanks in advance.

Yes i have unlocked the bootloader. I'm pretty sure i've already tried that version of TWRP, but i will try again tomorrow.
I always flash recovery using "fastboot flash recovery (file name)" so that's not the problem.

I think i might have found the problem.
When i go into bootloader it says FRP lock, i've looked around a bit, and i cant seem to figure out what it is and how i can unlock it.
If you know, how?

I had same problem. I successfully unlocked bootloader but after that I accidentally restored default settings in developer settings and oem unlock was ticked off and greyd out. Then I noticed the same FRP lock.
I had to relock and unlock the bootloader. Only after that I was able to flash twrp on my phone.
To relock you type "fastboot oem relock (unlock code)"
After that you can turn on "oem unlock" and "usb debugging"
And yes, It will wipe your data when relocking and again after unlocking so it takes some time. Hope this helps :fingers-crossed:

Question Allow oem unlocking option missing in developer options

So, i recently flashed arrow os 12.1 on my poco x4 pro (veux) using twrp. Flashing the rom removed twrp and now i cant flash it back because fastboot says that my bootloader is locked...
Of course, it isn't and the problem is that allow oem unlocking isn't on... I really would appreciate some help because i've been stuck on this rom for a day.
Gonna wait for some answers, thank you.
In the first place, flashing the rom shouldn't relock your bootloader. Can you please reboot to fastboot mode and use mi unlock tool with the same account you used to unlock bootloader first time.

Thank you for your response. Sadly i already tried that and the tool says that the phone is unlocked.
I'm trying to reflash stock rom via EDL mode, but i always get some error.
By the way, when using fastboot getvar command, it says that my bootloader is locked.
So, i recently bought a poco x4 pro (veux) and flashed a custom rom using twrp. Sadly, the rom's recovery managed to overwrite twrp and when i tried to flash twrp back, i could not flash it because fastboot said my bootloader wasn't unlocked. When i tried to unlock the phone again the xiaomi tool said that the bootloader was already unlocked. So, i used the getvar command which said that my bootloader was locked. So, i remembered that i didnt turn on allow oem unlocking in developer options. Sadly, when i looked for it the setting wasn't there. I tried using Edl mode to go back to stock but with no success.

Go to service centre if it is critical. I have never seen such case so i couldn't help. I am afraid that you would have to pay the service centre people money for reflashing your device.
Also have you tried flashing fastboot ROM (MIUI) through fastboot? Also try to flash stock recovery rom via the recovery you have now currently.
Another thing you could try is using the Xiaomi official flashing utility (which is not unlock tool) to flash stock rom which does not require OEM unlock.
