My Pixel 3a had a unlocked bootloader, I tried locking the bootloader using fastboot and it did lock the bootloader but after that it didn't bootup and gave error saying "no valid software is found... then I decided to unlock the bootloader again. After unlocking the bootloader device booted up but the SIM Card wasn't working. swapped Sim's but non of it work. I tried factory reset but it gave following error:
E:[libfs_mgr]unknown volume for path (/data] E:unknown volume "/data"
Data wipe failed
There's also no e-sim option in the settings but before doing anything there was 2 imei numbers as now it showing only 1.

If there bootloader relocks when you restart the phone, the memory chip is probably damaged.
Hi Experts,
I just bought an unlocked OnePlus 7 pro.
I confirmed that it is unlocked. If I go into settings, wi-fi & internet, Advance (Network Unlock) ==> It says the following "This mobile device is permanently unlocked and can be used with any carrier!".
So now, I turn on the developer mode, USB debugging, OEM Unlocking, and boot into Boot Loader mode.
In boot loader mode, I see at the bottom of the screen that it is locked.
Now I try the following command from my machine (connected via USB to the device) ==> "fastboot oem unlock"
I get the following error ==> "FAILED (remote: 'Please flash unlock token first.')"
So what am I doing wrong?
OR is it that even if it is SIM unlocked, I still need another UNLOCK for boot loader?
I saw the method to request it from T-Mobile via OnePlus website,
But my question is if it is already carrier unlocked, do I still need that "bin" file for boot loader unlock?
If that is true, then I suppose I have to request it, wait 7 days right?
Is there any way to do this, without this craziness?
Use the msmtool here. If you haven't already.

"Can't find valid operating system" on bootup, bootloader is locked so I can't flash
I was locking my bootloader because I didn't want to have my phone rooted anymore. So, I factory reset it, set it up, and then went into the bootloader and typed "fastboot flashing lock". I selected yes to confirm the locking of my bootloader and then my phone rebooted. But now my phone says "Can't find valid operating system" and I can't boot into Android. I can't even flash a stock image, because I locked the bootloader. I can't unlock the bootloader, since I can't go into the OS and turn OEM Unlock on. Am I screwed?

Factory reset doesn't reverse changes made by rooting, you needed to reflash stock firmware before relocking.
Depending on the model it likely isn't good, every OEM does things a little different.

but I tried to install an update and not a flash that you are not allowed to install
I have a phone (Moto G8), I wanted to get rid of TWRP and I thought that just locking the bootloader will do it.
I only after saw that if you lock the bootloader with TWRP flashed you get into a boot-loop.
I found out that I can only use "fastboot boot" to boot into stuff because of the error stating: "Your device is corrupt. It can't be trusted and will not boot.".
Even if I go into the recovery mode the same error message would appear.
I know that by unlocking the bootloader I could get rid of that error but I don't have an unlocked bootloader and,
as most of you already know, after relocking the bootloader you need to enable OEM unlocking from developer options.
That was a huge problem since I couldn't access the phone at all besides the
bootloader, TWRP (although limited by the locked bootloader), and the default recovery.
That way I got into TWRP but I couldn't do much because of the locked bootloader.
Even if I had a full backup (which I didn't have) I couldn't do much.
I also tried downloading the full OTA image of an updated version of Android (I had Android 10 and I tried to go to Android 11)
to sideload but I couldn't find it. I found one but it was not a full OTA image (with bootloader, recovery, etc.) and I got an error message saying:
"Invalid zip verification signature" or something like that. Also, the error was happening at the start of the ADB sideload, I didn't know what else I could try.
So I have a question: Since I can use "fastboot boot" to bypass the error message,
is there maybe a bootable .img file that I can use to boot directly into the system and enable OEM unlocking?
Any help would be highly appreciated as well any other way to enable OEM unlocking through the bootloader or somehow ADB.
Used MSMDT to reset to TMO firmware on KB2007 (OnePlus 8T) and now bootloader is locked and unlock token doesn't work again "FAILED (remote: 'Error - Verify Failed ! (4:-2)')" and my bootloader is permanently locked. Any help would be appreciated.
The MSM Tool returns the device to the way it was when you took it out of the box and booted it for the first time. Do you have USB Debugging enabled in Developer Options? You only need the token once. Have you tried using ADB to unlock the bootloader?
I checked oem unlock in the settings, and then tried to flash twrp and got an error saying the device was locked, tried fastboot oem unlock, and it told me to flash the unlock token, but it won't accept the token.
Try requesting another through OnePlus Support then.
