[SOLVED] Can’t unlock bootloader, can’t boot into the system after he has been unlock

So i have both the short story with some important explanation and the long story on what I've already tried.
Short story
So my dad bought a oneplus one 16GB from someone and the phone has a bootloop when you try the boot into the system.
I tried to unlock the bootloader, but it runned the command and it just reboots to recovery and the bootloader is still locked.
Also the tamperflag is true so that means that the bootloader has already been unlocked and is relocked.
I can't also boot from a custom recovery image because the bootloader is locked (I think it can with CM11S).
Rom: I guess it is CM12S (with the blinking Cyanogen logo at startup).
Recovery: probably the recovery from CM12S (Cyanogen recovery as text and it is a touch recovery).
Long story
So I am going to tell you my story.
My dad bought an oneplus one (16GB) from someone that had a boot loop at startup.
When he told me that I just thought that it was going to be pretty easy to fix: unlock bootloader, flash custom recovery and install a custom rom.
Now, it didn’t roll out as we both expected.
When I unlocked the bootloader it told me after 10 seconds that it was OK.
Pretty weird was that it took so long.
After some research I found that you need to reboot from the rom with adb and that you then can unlock the bootloader. On all my other devices I did that, but now I couldn’t because I wasn’t able to boot inside the rom.
After I “successfully” unlocked the bootloader I did the command “fastboot oem device-info” and it told me that the bootloader was still locked but it was tampered.
I tried after that to boot from a TWRP recovery image but i wasn't able to because the bootloader was locked.
After some research I came at a post on the oneplus forum with a guy that approximately had the same issue except that I can still go into recovery.
I founded this post.
And I first wanted to see if I couldn’t go into recovery and sideload a zip that is signed. That was signed in this thread.
As it expected because I didn’t had a custom recovery it didn’t worked and also I used this tool for adb and fastboot.
I didn’t give up by that one so easily so I tried it with this to sideload the files and I renamed it this time to update.zip. Again as expected an error but this time it was another error.
There came a bunch of errors on the phone especially cache errors and one that said that I had an outdated ADB (at least version 1.0.32).
Weirdly enough I had version 1.0.32 .
And now it tried the trick they told me here.
From the thread for windows 7 and 8 here.
I first did this without “erasing the bootloader”.
I tried this both on windows 8.1 and on windows xp with both administrator rights and I switched between 3 cables each time.
As you see in the attached zip, I correctly installed the driver, this was also the fact for the pc with windows xp.
I also verified the files but there were some that failed (also in the pictures).
It flashes the file 8974_msimage.mbn and then the phone shuts down. I tried this at least three times for each computer.
Then I founded this thread.
And tried this also and exactly the same problem as with color.
Then I tried the same with erasing the bootloader and it had the same issue and I couldn’t erase the bootloader doing to that my partition table doesn’t exist(also in the pictures).
The only thing that I only think that I can do is with a flash tool that uses also the above method but I don’t find any with that I know how to use it.
Any help is appreciated.
Ps: I attached a zip file with some pictures to make it more clear and understandable and i am also dutch, so sorry if my English is bad.

Sadly enough when I typed the command now it takes forever to answer, after more than 10 minutes it still displays that it is waiting.

Yes, i can also enter stock recovery but i am unable to boot from custom recovery through fastboot. Because the bootloader is locked.

Yes, after - + 10 seconds it says ok and it reboots the phone to the stock recovery.
When i try to flash twrp it just fails because my bootloader is locked.

Which stock recovery is it? ColorOS? CM? Or OxygenOS?
I had a similar issue when I tried to unlock mine when I first got my OPO

My dad bought the phone from someone and the only thing i can see is cyanogen recovery. At boot i have a blinking cyanogen text. Probably it was already unlocked because the tamper flag is tampered.

Maybe my previous post was a bit confusing but it is still locked, i meant that the previous owner locked it and then relocked it.

Can you tell us the exact copy/paste and output of below command :
fastboot oem device-info

I already founded that thread and did the solution that worked for him and another solution that a guy a few posts above him mentioned. Sadly enough without any results.
Anyway, thanks for the help and all the effort you did!

I just am going to mention it here before I will do it, to avoid to make the situation more worse then it already is.
So you can enter qualcomm hsloader (connect the phone to the pc, press 5-10 seconds volume up + power, screen remains dark).
And there are two tools (which have both the same base) here and here .
Now, when I follow the guide for both tools, always when it flashes the first file (8974_msimage.mbn), after flashing the phone shuts down.
And yes, I gave it administrator rights and the drivers are properly installed.
I tried it also on windows xp (completly clean test computer, yes I have a lot of them )
Now I saw on the oneplus forum a post .
And when I tried the command "fastboot erase bootloader" it gave me the following output:
C:\Windows\System32>fastboot erase bootloader
erasing 'bootloader'...
FAILED (remote: Partition table doesn't exist
)
finished. total time: 0.006s
Well if I try this with the command to erase the kernel partition "fastboot erase boot" I think.
Well might this then work, so that the device after flashing the first file doesn't shutdown?
Again I just want to mention it here before I make the situation more worse then it already is.

Now actually i think that the partition bootloader doesn't exists but boot does (which I think containts the bootloader and the kernel).
After waiting very unpationtly -+ 24 hours I tried it.
Sadly enough again without success.

Hi,
I am stuck with a similar issue. Only the way I landed in this situation is slightly different.
Without unlocking the bootloader (I just forgot to do that!), I ran the below command.
Code:
fastboot format cache
It erased the cache but failed to write to it because the device is still locked.
On rebooting, the device was stuck overnight on the "Cyanogen" display screen.
I forcibly powered it off using the power button.
Then I fastbooted it.
Then from the command prompt I tried to run a few commands - see output below
Code:

The command for unlocking the bootloader is "fastboot oem unlock" not "fastboot unlock oem".
Also sometimes when you type a commando that isn't recognised by the phone it can take forever.
So, I think that the commando "fastboot flashing unlock" doesn't exist.
Anyway I think I know now for sure that the previous owner erased and/or formatted the cache.

I'm not very familiar with Linux. The latest firmware is compressed with a newer compression method which older versions of fastboot don't handle. What do you get if you run the command fastboot --version? The latest is 28.0.1

sliding_billy said:
Have you tried to get into stock recovery from fastboot? I don't see a screen grab of that. Use key combo to get to bootloader, and then select recovery from fastboot to get to the no command screen and power +volume down to get to recovery options.
Also, did you get a prompt that unlocking the BL would results in a factory reset and did you do one?

You are right about recovery>fastboot. That is why I "deleted" my comment. Maybe starting back over might help. Were you running BL unlocked already? Did you have TWRP installed? Had you been using the same computer /cable/port to execute commands before?

Rename the patched boot.img to "boot.img", then place the patched .img in your fastboot folder on PC then type:
fastboot flash boot boot.img
When you place the file in your fastboot folder, you don't need to include the path to the file in the command, it automatically looks for the file in the fastboot folder by default when you do not enter a path. Renaming the file to "boot.img" isn't necessarily required, but, it does simplify things for fastboot and makes the command easier to remember and type.
The same applies if you want to flash a system.img, recovery.img, etc.. Just change the name of the file to "system.img" or "recovery.img" and place it/them in your fastboot folder and it simplifies your commands to:
fastboot flash system system.img
And
fastboot flash recovery recovery.img

You've to unlock device's bootloader. Hence 1st of all if you want to manage the / operate on the bootloader you have to move device into fastboot mode and then run on device if it's launched 2015 or later
Code:
fastboot flashing unlock
[code]
instead of the outdated
[code]
fastboot oem-unlock

The platform tools you actually use are meant to be used with Google devices only.
Use the Android USB-tools provided by your device's manufacturer.

I'm having simular issue with my specter 8 tablet. I unlock the bootloader and give me the normal prompt. I go back do everything else and will execute reboot devices ect. However won't flash patch_boot.img brings up message
FAILED (remote: 'Download is not allowed on locked devices').

tecno unlock bootloader?

so i am trying to unlock bootloader in my device tecno spark 8c i enter the fastboot mode and tried the command fastboot oem unlock it say message ok but nothing happenes if i try to flash the vbmeta it says the bootloader locked and need to be unlocked how to unlock it?

What happened is that you got a OK, means phone's bootloader now got unlocked.
To deal with bootloader you run Fastboot commands from the Windows shell, either CMD or PowerShell.

no it didnt get unlock it only say message ok
i tried this command fastboot getvar unlocked
which give me message unlocked:no and i am running linux so i am using its commandline working with it and as i say it didnt get unlocked what is the problem i cant figure it out
