I was installed with Twrp and had rooted my oneplus 3.
I unticked root access in supersu.
Booted to bootloader and typed on my pc in command prompt ,"Fastboot oem lock"
This gave a confirmation on my device,I confirmed locking.
And after that my device did not booted up.I managed to get in bootloader again as I was not even able to open the recovery and unlocked the bootloader once again by this my device booted up.
I flashed stock recovery and repeated the relocking process,this time I was able to open recovery also but no able to boot up.
I again unlocked the bootloader and installed twrp back turned my device up.
Then I unchecked oem unlocking under developer options.
Relocked the bootloader once again.
And now I am stuck at bootloader,not able to unlock it even this time as I turned off oem unlocking.
Now I can only open bootloader.
Please help!
thanks in advance
There is a thread about Hard Brick fixing.
Normally it should work it's using low level tools.
I just can't understand this obsession to relock, there is absolutely no need to and can lead easily to a cold brick.

Hey everyone,
My nexus 5x froze shutdown yesterday.
My phone uses TWRP and Cyanogenmod. After it happen I couldn't even boot into *recovery* ! The phone just "turns off" and I cannot turn it on for quite a while.
Eventually I was after to get into bootloader to use fastboot.
I tried to reflash the recovery. The flashing worked but I still couldn't boot into recovery.
I read somewhere someone who wrote that he/she locked and than unlocked the OEM lock and it worked for some reason, so STUPIDLY I locked my OEM, and when I try to unlock again it says I cannot unlock it (although I did enable OEM unlock in the first place, that's how I flashed in the first place).
SO HERE's the bottom line:
I am stuck with OEM lock enable and ONLY fastboot (cannot load into recovery).
I thought I installing OTA (which I can install with OEM lock), but I need ADB for that which I don't have.
ANY IDEAS????
THANKS A LOT IN ADVANCE GUYS!
Hi friends
Please give me suggestion or guide how to solve problem about handset booting after mistakenly handset OEM locked through fastboot
It enter to fastboot mode but not going to recovery mode or restart in system mode
Is there any solution
If yes then please help me
fastboot oem unlock ?
Actually ive unlocked OEM and install twrp recovery and installed freedom os
Then while checking OEM status ive enter command fastboot OEM lock
It ask me I've pressed yes after that the massage is came after restart as your device is corrupt it can't be trusted and will not boot
After that it enter to fastboot but not going to recovery mode or system
While type command in fastboot OEM unlock massege come failed
This happens because your bootloader has been unlocked at one time. There is no going back, even if you use "fastboot oem lock" later.
Edit: Just noticed the part about your device will not boot. You need to find the system image and flash it. I read somewhere today that OnePlus just released the system image for 4.7.4.
Can you unlock again?
@op, IMHO the best possible solution will be to flash stock rom image and stock recovery if required but I think when you flash stock image it will also flash stock recovery.
When you turn off the phone and boot it with VOLUME UP plus POWER, this should send you straight away to Fastboot. Try if you can unlock again, otherwise... bad luck - you'll need a restore session with 1+.

Not to be unrespectful, but you're wrong, it is absolutely possible to relock bootloader without problems.
IMHO, trouble happened because he had a custom rom onboard... and a locked bootloader does exactly its purpose... to not boot insecure firmware!

After looking into it further, I agree with you. That's what I get for having a bootloader-locked Samsung device for two years. I must be getting rusty!
Yes, the bootloader can be re-locked. There may still be a tamper flag as with previous OnePlus devices. But having a locked bootloader with non-OEM software would likely cause the problem he is describing. So, he needs to flash the factory image from bootloader.
I've requested to 1+support for restore remote session
Support send me file link and l2 will assist me in within 2 days
DO NOT RELOCK BOOTLOADER UNLESS U READ UP FIRST!!!!!, its worth just waiting the few seconds after reboot, then to go and try to relock the bootloader

Did you by any chance re-lock the bootloader with a custom recovery and custom ROM flashed?
It's because of custom recovery.
Just flash stock recovery image before locking the bootloader.
This fixed for me.

You unlocked bootloader, flashed rom (custom) and relocked bootloader? Never lock your bootloader on a custom rom! Just enter fastboot again flash twrp (manual/force reboot recovery), copy internal storage to pc then wipe/format everything. Format data. Factory reset then flash latest official rom and reboot
After tried to install stock rom on my pixel2 xl, i locked bootloader.
Now, i cant unlock bootloader because i cant boot and check oem unlock.
When try to boot into recovery, and boot to android, just appear message "can't find valid operating system"
What to do?
I tried unlock bootloader from adb, and get the message that is not allowed in lock state
Everything i can is boot in fastboot mode.
Is there any possibility to unlock bootloader without check OEM unlock, because i cant boot anything?
Please help.

Why did you lock the bootloader anyway?? If you can't get to the OS to check OEM unlocking and USB debugging....your hosed as far as unlocking the bootloader again. And since you have no recovery now, you can't side load an OTA to get your OS back. Might as well RMA it I'm afraid
Please people, read this and understand me clearly...
Unless you have a very very VERY good reason to relock the bootloader. DO NOT. The risk is too great for no reward.
This is the second or maybe the third post this week alone where someone may have hosed their phone doing just this...
I'm not here to hammer the OP but folks gotta understand.
I waited the 72 hours and then ran the program on my PC for the Mi Unlock, and then afterwards I wiped the phone clean, flashed TWRP, and put on miui10, forgetting that doing a data wipe resets the Mi Unlock status. Do I really need to reunlock it, cause if so it will delete all my data again..
Edit: It's just odd because on the bootloader screen, 'fastboot oem device-info' shows my bootloader unlocked still, I have Magisk installed, running joeykrim's Root Checker from google play shows root access not properly installed, running flar's DevCheck from google play shows the device rooted, I have BusyBox installed , and lastly, in the Developer options, OEM Unlocking is ticked on, but doesn't say already unlocked, and the Mi Unlock status still shows locked. Lots of conflicting info here, so just a bit wary since this is my first Xiaomi phone.
I went ahead and tried unlocking again with the tool and I get this (see screenshot)
Usually unlocked only once, but if your device is locked again, it can be unlocked without any damage. Don't know what ROM you use If it is a world class ROM, ctf will not pass. For magisk, you have to modify the fingerprint to pass. Try studying. You have to do it. Good luck.

WEll everything is running fine being rooted. MAgisk SAfetyNet passes, rooted apps work fine, but Mi Unlock still shows my phone is 'locked'm but fastboot says it's unlocked. And I'm using the official miui_MIMIX2Global_V10.2.2.0.ODEMIXM_a92827160b_8.0 rom and fw_chiron_miui_MIMIX2Global_V10.2.2.0.ODEMIXM_a92827160b_8.0 firmware
You don't have to worry. I think your device is already unlocked. If the device is still locked, you cannot install twrp.
yeah thats why im confused. everything works fine. i guess i wont worry about it unless i come to a problem
Hey guys, Is IT possible to unlock bootloader without approval trom xiaomi? I used mi unlock app on my Pc before approval, and It seems that my phone Is succesfully unlocked. Even in console on Pc it days that the device Is unlocked.
However, I can't flash twrp (It still boots into factory recovery), so I cannot root.
Any help on this case? Do I still need approval and do unlock process again after that?

What happens when you flash twrp?I mean it says failed or successful.
You can run this fastboot command to get bootloader status: fastboot oem device-info

Actually..I got it to work. But when it booted into twrp, I doesn't have magisk copied on phone storage.
Then I tried to reboot phone normally, but I got bootloop. Then I flashed fastboot rom and then it booted into system, but my phone is locked again.
