Has anyone unlocked phones with Android 11 without deleting the data?
pls help me??
give a tutorial
Android smartphones automatically reset after unlocking the bootloader. If you don't mind losing data, however, you can enable OEM unlock in the settings, assuming your phone does NOT have a carrier lock. After that, you just need to reboot it into fastboot mode. (you can do this using ADB or by pressing the correct button combination.) Finally, just run
Code:
fastboot flashing unlock
and
Code:
fastboot reboot
CAUTION: YOUR PHONE WILL RESET.
Yeah after backing up RPMB
I meant lock screen without losing information

I am trying to install stock firmware through fastboot. After typing below command,
Code:
adb reboot bootloader
the Device reboots but Fastboot mode only shows for 1 second then the Device reboots to system.
I have Usb debugging ON, OEM unlocking ON
Tried on 2 different PC's. Also tried removing Usb after command.
Reason for stock flashing is just that I used this ADB command on my phone and It lost IMEI: By this method and here is the detailed problem.
UPDATE: Took the phone to service center, they changed the Mainboard. But then Fingerprint was not working (couldn't enroll). They took it again and tried stock flash and fingerprint sensor change but the issue persists, still diagnosing.

My phone has lost Network service and IMEI is null. I did not root. I did this: Method
Does that mean I need to unlock bootloader to flash the stock ROM? Is there any other method? I don't want to lose warranty.
The phone does boot to EDL mode.

Can I achieve this without voiding my phones warranty?
I finally took the device to service center. And the executive said he would send the case to Realme and he is not certain that it would be covered under warranty as the imei is broken. But my device's bootloader is untouched and I never tried rooting.

I already found the solution, but it will erase your data.
with the adb commands you must restart the device in boorloader mode:
adb reboot bootloader
Then when I take you to the bootloader screen what you have to write next:
fastboot oem lock
(Remember the phone will be erased)
then to restart the device you have to:
fastboot reboot
And the device will reboot.
what you do is lock it, so that you can then unlock it in a simple way.
(If you do not know what the ADB is, warn man), I hope it helps you and those who enter here too :good:
@l3dson: Be careful before relocking the bootloader: The phone MUST be 100% stock or you will have a brick.
@Mohammedbi: Your bootloader is still unlocked, even after flashing the KDZ. It's just the newly flashed ROM doesn't know it, and you don't need it to.
Just go to fastboot (PowerOff, Vol- while plugging in cable) and flash TWRP. Follow ChazzMatt's root guide for the initial TWRP steps.
Have anyone found the solution for this problem...

What exactly is not working?
ADB doesn't require Enable OEM Unlock to be set. Just plug it in and ADB away - unless drivers or cable or port aren't working.
And your bootloader is still unlocked if it was unlocked before you flashed stock Oreo. You should be able to enter fastboot using the steps described in the post just before yours.
Edit: Of course you have to enable USB debugging in order to use ADB. I'm sure you knew that

hey i have this same problem and been asking around... but the adb reboot command will not work because it says the phone must be "enabled oem unlock" mode before you can use adb commands... which is greyed out..so back to square one... how to enable it?? any suggestions on this??
How to :
1. Enter fastboot mode
2. Run these code:
Code:
fastboot oem lock
What will happen:
1. Bootloader will be locked, if you rooted or flashed twrp, renmenber to flash official firmware before relocking.
2. widevine level will be restored to L1.
3. All data will lost after relocking.
4. DRM key? I don't think we need it now and IDK if it loses either.

Could please upload the screenshot of the page configuration from the menu service?
Also, I advice you to hide your IMEI for security reasons

You need to use Xperia Companion to repair firmware.

I read many times and I still don't understand how to "run the code fastboot oem lock". I'm trying to reset and relock bootloader on phone after Sailfish
When unlocking the bootloader, you entered:
fastboot oem unlock (+ code from Sony)
when locking the bootloader, just type:
fastboot oem lock
Everything works, I have done tp several times.

I looked the instruction-but I don't sure that the running of cmd in path with Sailfish is right after reinstalling Android. I have no Sailfish more. Can you please tell me where I chave to run cmd, in which path? Thanks
Yees, I made it. Lots of thanks. I have no warning more and updates are coming

give this a shot https://github.com/bkerler/mtkclient
If I'm not mistaken that's only for mediatek chips isn't it? The a3x/a600dl is using a Qualcomm 460.
ah if its a qcom chip you're out of luck unless you can get a firehose for it
I have tried using fastboot on this device with no success. Anyone else?
Using ADB I was able to boot to the Recovery Menu, but my only options were
Clear Cache and
Factory Reset
Other things I tried with no success:
ADB Reboot to Bootloader, Fastboot, EDL
QFIL Flash Image Loader
Hardware Button entry to Recovery and Fastboot

Yes, seeing as I tried this for around an hour with no luck, only to find that TCL denies the user access to the bootloader. Even though you can see the option to OEM unlock in the Developer Options menu, TCL blocks all users to be able to access the fastboot bootloader. As someone else here has said somewhere, it is only possible when someone finds an exploit to get to it, unfortunately.
Take path settings, system, about; find build number and press it quickly multiple times until you enter developer mode. Go back into system and find developer options. Now you should have a toggle for unlocking bootloader
Hello everybody,
My phone's battery died and I charged it. When I tried to turn it on, I saw this screen. I've tried clicking on the options but it's stuck in a loop and I don't understand what's happening.
If anyone has experienced this issue before, I'm reaching out for your help. Please assist me.
Flashing factory firmware in fastboot might be the only option. Doing such will wipe everything on your device though!

Since your bootloader is locked the only way to flash the OS is to sideload the Full OTA via ADB or use Pixel Flasher to sideload it. If you happen to have OEM Unlocking enabled in Developer Options you can use Android Flash Tool as that will unlock your bootloader as long as OEM Unlocking is enabled. If it isn't, sideloading the OTA will be the only way to reinstall your OS to hopefully get you out of this.

Oops! You are right, mate.
Hello so I am stuck here
When I go to Android Flash Tool it's says :
"Device Unlock Disabled​For security reasons, you need to enable "OEM unlocking" in order to flash your device. "
And when I tape in CMD the command "faastboot falshing unlock" it says
"FAILED (remote: 'flashing unlock is not allowed')
fastboot: error: Command failed"
Is there a way to unlock the devices states I have seen a video when
when a guy is using a unlock.bin he download at LG offcial site. Does Google have an alternative where can I download this type of file for my Pixel 6.
Google doesn't have an alternative. If you can't flash the OTA, and apparently you can't because OEM unlocking wasn't enabled in developer options, you need to get a hold of Google and explain your situation to them. You'll likely have to send it back to them, if able to do so.
You can't enable OEM unlock by fastboot/recovery.
Can you boot into recovery?
If yes, then this is your only way out!

Use image of OTA, not Full!

Unfortunately, it is not possible as my phone is showing that it is locked and I am unable to access the settings to unlock the OEM, since I am stuck in fastboot mode. Guess it's dead only if there is a way to unlock the OEM without going to setting.

You misunderstood!
You don't get to do anything from fastboot with OEM locked.
I asked if you can enter RECOVERY mode?
If yes, then visit the link I shared.
btw, why on earth you are flashing 'adb'?

Unfortunately, when I go into recovery mode, it keeps looping back to the original screen in an infinite loop.
I lost hope and went to a repair shop, but they told me to contact Google. The customer service will send me a package to return my phone. I didn't know that the OEM was so important, I will activate it next time. Tanks for your helps ...
