Fastboot refusing to take commands after oem unlock

I recently used the newfound method of unlocking the Verizon Pixel/XL 1 to unlock my Pixel XL. The issue now though is that I can't flash anything, or do anything in fastboot. Windows doesn't see my device when I use adb reboot bootloader, and the console entry on the bootloader screen says DISABLED. Google is unhelpful as I seem to be the only person here with this problem. Any ideas?
For what it's worth, I used fastboot oem unlock instead of fastboot flashing unlock.

I think your problem is you used 'fastboot oem unlock' instead of 'fastboot flashing unlock.'

Well, now I see the problem.
Now I need to know how to fix it .-.

Yes, I did. adb works quite well enough, but fastboot detects nothing.

Hey there Xda members !
I've been trying to unlock my Whyred since past few weeks, i don't know what I've done wrong but here's what I've done :
1. Opened Mi unlock page to request for bootloader Unlock permission (but there isn't any such thing)
2.it automatically showed Mi unlock tool and I've downloaded it on my computer
3. Installed Mi usb drivers
4. Ran Mi unlock tool and connected my device in fastboot mode ( I've already binded my mi account)
5. Mi unlock tool detected my device and i pressed on unlock anyway
6.and it loaded up to 99% and asked me to try after 360 hrs
7. After about 16 days i reopened mi unlock tool and pressed unlock
8. It loaded up to 99% and said "Unkown error"
Can somebody suggest me a solution.
Please devs.

Ok

Please remove this thread, the problem got solved.

And the solution was?

I've done a factory reset and then again logged in when Mi account and again requested for unlock bootloader and a miracle it unlocked the bootloader. It took me about 40 days to unlock it.

why would you want to relock when everyone is trying to unlock it?

the re-lock and un-lock bootloader function,
is it the same as the OEM lock and unlock option in developer mode ?

Root method for Oppo A52

Hey everyone,
I have just purchased an oppo a52 and looking to find out if there is any root methods currently available. I have searched but unable to find any information about it.
Any help would be greatly appreciated.
Cheers

The first thing to look for is unlocking the bootloader which is not currently doable

Regarding unlocking the bootloader in the developer options menu it has an option for OEM unlock. Forgive me as I am very very basic at this type of stuff but would that have anything to do with unlocking the bootloader?

Nope that is not enough.
There should be access to bootloader first (usually through "adb reboot bootloader"), then the command for unlocking bootloader (usually "fastboot oem unlock" or "fastboot flashing unlock") should work. But none of this is available yet
Even the full ROM is not available on Oppo website yet. So nothing to develop here!

I just spotted it on India's site: https://oppo-in.custhelp.com/app/software_update_detail/p_name/A52
I know nothing about rom development myself, but hopefully it gets some sort of custom rom support in the future

I thought everyone said it's not able to be unlocked.
Although the setting is able to be changed in developer options. Has that only just been enabled due to an update?
So can we just enable the setting and run fastboot flashing unlock from fastboot. Backup before trying if someone does it.

it is not possible to unlock the bootloader.
The device is already over 6 months old, nothing else will happen.
With ColorOS11 many adjustments by Oppo disappear, it will be more like AOSP.
A first alpha of ColorOS11 went to the first 100 users last week.

Aren't these methods true?

Unable to relock bootloader without receiving message that says "Your device is corru

Unable to relock bootloader without receiving message that says "Your device is corru
Hello all, last night I used a flash-all tool to restore my OnePlus 7T from OOS Beta 6 with root back to 10.0.11 without root. After restoring to the stable firmware, I tried relocking my bootloader, upon which I received that message I posted in the title. It doesn't matter if I reset my phone in the recovery or through the settings app, I always get that message if I try to lock the bootloader again. I'm thinking I might have to use the MSM download tool, but I was having no luck with that last night since it would stay continuously stuck on param preload despite being detected by the app. I can use my phone normally again if I unlock the bootloader again, though, so that's what I'm doing in the meantime.

I was able to relock my 7T using fastboot. If you can boot to fastboot? In linux the command was 'fastboot flashing lock'. Not sure in windows if it's the same. Worked for me. Now 'OEM unlocking' option is visible again under system / developer tools. Prior to re-locking it was grayed out, unavailable.

Are you sure with the command? Shouldn't it be "Fastboot oem lock" / "Fastboot oem unlock"? I'm not sure because I never locked my phones again but this makes more sense to me than your commands.

Use the msmtoolkit it will lock your bootloader. I think that is the safest way to achieve a locked bootloader

I had same issue as OP so I went back to unlocked but I tried locking it through the all in one tool. Haven't attempted to do it through fastboot directly.
That msm toolkit doesn't work on the tmobile version however. Even if you flash to global, I believe the posts in the thread indicate that the model number is off and it won't work.
If there's a way for me to relock the bootloader on global, I'd definitely do it so I could get incremental updates back.

See my 1st post again. Why using all in one tools you never really know what is going on in the background when all you need are simple commands for the command line?
Just read up a little bit on adb and Fastboot, it is not so hard and the usage is very transparent, trust me. It helps you to better understand the process as well
Btw Fastboot and adb commands are the same on Windows and Linux

Here's a snippet out of the man pages for 'fastboot' on my debian box (fastboot version 1:7.0.0+r33-1 )
the bottom two entries -
--------------------------------------------------------
COMMANDS
fastboot update filename
Reflash device from update.zip.
fastboot flashall
Flash boot, system, vendor, and (if found) recovery.
fastboot flash partition [filename]
Write a file to a flash partition.
fastboot flashing lock
Locks the device. Prevents flashing.
fastboot flashing unlock
Unlocks the device. Allows flashing any partition except bootloader-re‐
lated partitions.
------------------------------------------------------------------
fastboot flashing lock worked for me, locked and under developer tools it gave me back "OEM Locking" option.
I thought windows was something like 'fastboot OEM lock' but I'm not sure since I didn't get there.
I'm a total newb if it ain't already obvious. lol

Being that this is Debian 9, maybe my fastboot is an old version as well. ADB and fastboot both seem to work pretty good though. No stinkin' USB driver issues like with Windows 10.

Hey, all. Figured out why I couldn't relock the bootloader despite everything being stock and unrooted.
Since I was using fastboot to flash a stock image, I needed to flash any image that wasn't the newest version and let the phone boot and install an update from OnePlus to bring it up to latest and THEN lock the bootloader.
So yeah. Use fastboot to install 10.0.09 then boot the phone and download the system update to 10.0.11 through the standard update tab in settings (skip whatever set up you can when it boots) and let it do that update. Then, once that's installed direct from OnePlus rather than via a fastboot image, then you can go ahead and relock and it won't give you the corrupt error.

Thanks. Confirmed this works. Needed to install an older version (went with 10.0.8 global), then skipped through most of the setup minus wifi, did a system update to 10.0.12, reboot to bootloader, fastboot oem lock, and no more corruption errors.
