Can't unlock bootloader - OnePlus 2 Q&A, Help & Troubleshooting

I have tried to unlock it as suggested by oneplus and it will not do anything.
I go into fastboot mode after installing the drivers on my PC confirmed I can see my device and when I executed unlock it did wipe my phone but didn't unlock the bootloader.
Anyone knows why it doesn't work or what I'm doing wrong?
BTW I have updated to marshmallow manually. This phone was never unlocked or rooted.
Thanks in advance.

Have you gone into developer options in the android settings and enabled the oem unlock switch?

Tried to run as administrator and it still does the same thing. Here is a screen shot of cmd when I execute oem unlock.

Best bet, run the usual restore to Lollipop factory image using the guides on this forum, and then try to unlock. It will probably work then. You should have unlock before you installed the experimental beta release of Marshmallow ?

Thanks, I'm going to Google it and try it out. I wasn't planning on unlocking it but when I saw that cm13 got the fingerprint scanner working I decided to do it as I miss my opo with cyanogen. I didn't expect to run into this issue as I have unlocked many phones before without any problems.

I couldn't revert back to lollipop after data & cache wipe. This is just turning into a real pain in...... Which I don't know or understand why.

Does it say it's unlocked with fastboot OEM device-info?
This is so strange because I am having the same problem

I'm not sure if this is unlocked or not since I couldn't flash twrp.

But in that photo it says "Device unlocked: true" which means it's already unlocked. And still you can't flash another recovery?
And remember you have to flash recovery compatible with your OOS3 bootloader version.

I got twrp 3.0.2 and still can't flash it

Had twrp issue myself.
Had to flash hybrid twrp flash oos2 to change bootloader and then update twrp via image flash for it to take.
All good now but bit of chore to do.
Look on the forum page and there is an all in one tool to assist you.
Hope this helps!

Go to fastboot mode again and flash twrp. DO NOT boot OOS or recovery will be overwritten. Do nand and install cm13 and gapps. Should work then.

Here's how I got mine to finally work. I flashed back to LP and than fastboot erased and flashed twrp 2.0.7 or one of the older LP ones. Try that.. That's how I got it anyway. I also downloaded a fresh one.. Not sure if that did anything but.. If you try and fastboot boot the recovery and get a btb error( I was) I was told that the boot IMG was messed up to get that error? Don't know.

Wow after 2 hours of softbrick I got it to work, did my nand backup and now going to look for a good cm13 rom.
I had to get a certain twrp recovery I found on YouTube and not the latest version from their website.

Use stock recovery for flashing this zip.. Without any issues.. As blusprark is showing an error of updated binary error...
I'm rooted with stock 2.2.0-x , can i flash the zip using the twrp recovery?
Is there a new modem in this update? I haven't used official OOS since getting my Oneplus x on release. Wondering whether or not I should flash an official update to get access to modems, touch drivers etc

Anyway, I'm rooted, using bluspark twrp and as far as the posts went, I won't be able to flash it.
Can I go back to stock recovery - flash this zip - flash twrp again?

You can use the 2.2.1 full rom. I have downloaded it from the oneplus servers and shared it on oneplus forum. I don't have enough posts to share it here.

COS13 OTA direct link (unzipped & flashable)

DOWNLOAD
I have unzipped it there so if anyone needs selective updates you can do it from there. It is latest CM-12.1>13.0 incremental
Transmitted via BACON
Added highly compressed COS12.1, unzip it and run flash-all.bat and you will be good to flash COS13 zip

If you are on COS12.1 unrooted then just download COS13 zip and flash it via recovery
If you are on custom ROM then flash COS12.1 images (from the first post) and then flash COS13 as zip from stock recovery

well, you have it in download mode in that pic, so it seems that youre wanting to flash a tar file via Odin. The pic is a bit blurry, but it looks like a G900F, is this the case? Does it not boot? What are you trying to accomplish? Whats the symptom?

i mentioned it earlier from what i could see in the pic
Yes I think I just need a Rom now for Samsung galaxy s5 g900f. I can't seem to find it, the ones i tried downloading were ridiculously slow eta 8 hours and keep falling.
I've installed Odin and the Samsung usb drivers on my pc.

well, if youre able to boot to download mode, then you might just need TWRP and a custom ROM. sammobile.com/firmwares (specifically https://www.sammobile.com/firmwares/database/SM-G900F/ for your phone) is THE reputable place for tar.md5's, but is known for its slow speed and if your computer goes into hibernate at all, the downloads will fail. But, you might be able to get away with flashing TWRP, putting your choice of ROM on to your sd card and installing it from there.

androidfilehost is always a good alternative, but finding one can be daunting. The G900F is a very popular phone, so it shouldnt be that tough to find actually
here is a german 6.0.1 tar.md5. Should have whatever other language youd need in it as well

Ok So I tried using that rom with Odin. But it seems to have failed. And it tells me to use "kies" recovery.
I even searched that And found the software, but it wouldn't run on Windows.
So just what am I doing wrong here?
I downloaded Odin installed it, ran it under ap I chose the German Rom listed above. After a while it appears next to ap so I start the process off and eventually it says FAIL on Odin and my mobile says I need to go into recovery with kies.
Uhm this is starting to annoy me now [emoji15]

LGV20 stuck on bootloop

Good morning. I BELIEVE my V20 was still rooted when this happened. I gave my phone to a friend to use, she updated it when it said there was an update. After she updated and she restarted the phone then it started the bootloop. I cannot get into recovery and when I try to enter download mode then it does what you see in the video. Does anybody know what I can do. The only mode that I can get to is fast boot. Even doing a factory reset does not work. Thank you in advance for all of your help.

Is there no one who is able to help me with this issue?

You say you were rooted. Have you checked to see if you still have fastboot flash available? If you don't, then no, there is nothing you can do if the phone won't completely boot to download mode.
There are 3 ways to fix an Android phone:
1 - download mode (if you have a KDZ) -- but your phone won't boot into it
2 - recovery (if you have TWRP) -- You say it was wiped by the OTA
3 - fastboot (if you have fastboot flash available) -- This is your last hope.....
If you have none of those, then only LG can fix your phone.

I am still able to get in to fastboot but I am not super familiar with fastboot as I am with download mode and recovery. When I boot in to fastboot mode, how should I then proceed?
To suhridkhan:
The issue is that the download screen shows for about half a second and then bootloops. It is like this every time.

Try using fastboot commands to get into recovery or download mode?

Ok, well I guess I will just have to wrap up this forum as no one seems to have or know a answer. So I will just toss the phone. Thanks anyway.

People have moved on from the v20. Only a few remain and apparently no one has had your issue. Sorry I couldn't help but don't give up, good luck
The engineering aboot was overwritten by the OTA, so no, there is nothing you can do except send the phone to LG ot hope that one of the firehose methods works.

Yeah I know. I myself have moved on to the Note 8. It is just always good to have a back up.

Is that really worth it though? To send it back to LG? I kinda figured that was the case but I wanted a confirming answer. Thank you for your input. I truly appreciat it.

Lg v20 us996 only booting into fastboot mode.
My phone is only booting into fastboot mode and bootloader is locked. It is booting into download mode for just a second and then it goes on device is corrupt screen. How to unlock bootloader now. I have requested unlock.bin file from lg but they are not able to provide this file for my phone bcz device id and imei are not matched. Seems like my phone is refurb and motherboard hasbeen changed. Lg developer said that they will update the device id and then provide unlock.bin after 10 days.
