Question It does not start after unlocking the bootloader and the inscription orange state appears - OPPO A54

Tell me how to remove orange state after unlocking the bootloader? there is also a problem, the body does not enter the fastboot, when trying to log in, it writes: the serial is not match fastboot unlock verify fail and after a few seconds the inscription orange state. the phone does not start and does not enter fastboot. it is included only in the recovery. I tried to flash through recovery writes that the version is lower than the updated one. what to do about it?

Orange state warning is quite normal after unlocking bootloader. Fastboot won't work, instead you can use fastbootd. Just use adb and type "adb reboot fastboot"

[Q] Unrecoverable bootloader error - Bootloader locked

Hi,
I would like to know if there is anyone who knows how to unlock the bootloader on a TF300T with the Unrecoverable bootloader error. I have access to fastboot, yet the "fastboot oem unlock" command doesn't unlock the device.
The entire device is wiped due to following another tutorial for fastboot to recover from the bootloop error, so there is no more way to enter recovery or cold start android... the device has two options, fastboot mode, or being stuck at the asus logo untill the battery runs out. Adb doesn't recognise the device, even with windows drivers installed.
I can't flash anything with fastboot as the bootloader is locked.
Is there a way to unlock the bootloader, or is it gonna cost me repairs?
Grtz

Need help getting in to fastboot

Hi!
I unlocked my phone - but when i type in the command "adb reboot bootloader"
it goes in to fastboot for a second, and then I get "bootloader unlocked" warning and after that it boots in to android.
How can I stop at fastboot to flash a custom recovery ?
Cheers!
EDIT:
NVM fixed
I am sure it was the right way.
How did you get it fixed?
I turned it off completely and after that, it accepted the command and stayed in fastboot.
Good to know, thanks for the information.

If the "orange state" is "Your device is unlocked and cannot be trusted", you will most likely have your bootloader unlocked.

So what to do I need to lock my bootloader
No need to relock. What happens when you presses the button combination of fastboot mode (search Google)?

Take note that as soon as you re-lock the bootloader the bootloader simply gets forced to load phone's Stock ROM.

[Solved] Unable to relock Bootloader of J9210

I have a J9210 which I had unlocked the bootloader and did experiments with it. Today, I decide to revert it to stock firmware and try to relock the bootloader.
- I have restored the firmware via EMMA, it applied the UK firmware to it, running build 55.1.A.3.49
After applying I had run these commands try to relock the bl:
- fastboot oem lock
- fastboot oem unlocked
And they both returned `Command not authenticated`
I also tried to run `fastboot flashing lock` and it returned `Command not supported`.
I will be grateful if someone explains how to it. Thanks.
I have solve the problem, it was my mistake.
The fastboot mode for locking bootloader should be the blue indicator, not the green one.
For anyone who finds this page in the future:
Power off the device.
Hold volume up + plug in the USB-C cable at the same time.
keep volume up held until you get a blue notifacation LED. (should take about 10 seconds)
make sure fastboot drivers and platform-tools are installed on your desktop OS of choice.
run this command in the platform-tools folder:
Code:
fastboot oem lock
then run:
Code:
fastboot reboot[CODE].

Re-lock bootloader ?

Hello all
I was wondering if anyone has successfully managed to re-lock a bootloader (on a stock ROM) ?
I got an A51 that I kept as a backup but decided to give it to my aunt instead.
But I'd like to get rid of the the pesky message at boot saying "your bootloader is unlocked, dangerous, blah blah" before I give it to her.
I've flashed the latest stock ROM but it doesn't get rid of that message...
So if anyone has an idea, I'd appreciate it
Try it
adb reboot-bootloader
fastboot flashing lock
or
adb reboot-fastboot
fastboot flashing lock

How to Relock Bootloader Galaxy A51
Hi, for those of you who have already unlocked the boot loader before, and if one day you change your mind to lock the bootloader again, here's how (remember, This will wipe your data again!) - Shut down your device. - attach the data cable to...
forum.xda-developers.com
Yeah, I tried that already ("fastboot oem factory-lock" for example, as well as some others), but each fastboot command just yields a "< waiting for any device >" message and nothing happens...
And when I try "adb reboot bootloader", the phone reboots in the fastboot mode, but all I get is a message "entering fastboot mode" (or something similar, I can't recall exactly).
Also, when I try sending some adb commands I often get a message saying "
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device."
