Are you sure you entered the boot loader key correctly, i. e. capital letters and no spaces?
The key has to be entered exactly like this:
Code:
fastboot.exe -i 0x0fce oem unlock 0x[I](your correct key)[/I]
Good luck!

Chipy

Very strange!
Could have some reasons:
1. Are you sure, you entered the correct 14 digits of your IMEI, when you asked for your unlock key on Sony?
Normally, the IMEI has 15 digist, but you have to leave the last one away.
Did you do so?!
2. The command fastboot oem unlock KEY has to be entered following the right folder structure.
So try the following: Open your Explorer. Go to the folder of your "minimal adb" installation.
Let's suppose you installed in on the partition E: into the folder Minimal ADB and Fastboot.
By the way: You didn't mentioned which system you're running. And it's harder then to give correct instructions.
On Vista, right click on that folder and choose "Open Command Prompt Here";
on other Windows versions it should be similar to this.
Now, the commander opens and should say something like: E:\Minimal ADB and Fastboot>.
And then write adb devices. Wait for the output.
If you get your device listed there, you did it right.
If not, you made something wrong.
If this shouldn't work again, please, be so kind to give us a detailed overview of all the steps you exactly did.
Good luck!

Try to get another unlock key from sony.
When I unlocked my bootloader I didn't use the unlock key for a week and when I finaly had time to do it I received the same error, so I went back to sony website and requested a new unlock key. It worked like a charm.

... and let us know, what's your result!!!

Hi there,
I must try here, and ask.... If you could help me with unlocking my bootloader.
I tried various "no boot needed" rom-s and nothing worked ! Whoever I try to ask, nobody is saying anything useful.
My t-mobile (phone is locked, only for theirs sim cards) is saying that's locked by sony, local service guy is saying something different and I don't know which side could I believe !
I would like to change that "bootloader unlock allowed:no" to yes
and after that- install ultimate hd rom. So I would ,kindly, like you to point me (what) and how should I unlock my boot loader. (I believe, there are ways and it could be done)
Big thanks and best wishes !
Željko :good:

Hi Željko!
As far as I know, the information in your device Bootloader Unlock Allowed has to be positive, i. e., saying Yes!
Otherwise you can't unlock your bootloader for free and have to choose a paid unlock.
Sorry for not having better news for you! =/

that's positive :laugh:
positive that it can be unlocked.. either way, it's going to be cheaper than new mobile phone
The best I was hoping is some homemade method, but... this is ok
another question !
When I contacted that local servicer, he said that some bootloaders can and some can't be unlocked (on lt18i), would you know why or is that true ?!
and, btw, I asked for price... he said, if unlocking is successful he's going to charge me around 20usd (just for reference)
Thanks

remote: oem unlock is not allowed

Hi,
I am using my Nextbit Robin Oem Unlock from last 1 year but today i decided to go back to stock with locked Oem.
I flashed the stock rom and locked the Oem at the same time but when i restarted the phone it got stuck at the boot.
So I went ahead with the 'fastboot oem unlock' command, and here's the problem. All flashing command returns FAILED <remote: device is locked...>.
fastboot oem device-info reads: Device tampered: false, Device unlocked: false. So bootloader is locked. At this point I assume that the bootloader is unlocked, but revert back to locked after reboot (the phone automatically rebooted after executing oem unlock command, so can't get around that).
Tried numerous other methods, using different adb files, no dice. Can't even flash TWRP. Tried adb sideload, same. Tried executing fastboot oem unlock with various different parameter, still locked after reboot. I cannot flash anything into locked bootloader.
Google researched it for few hours, same problem happened to other phones from other manufacturers that came returned from warranty replacement with modified motherboard; OR tampered/broken eMMC/NAND flash. But no such case for Nextbit Robin (yet?).
Pretty hopeless right now since I just found out that Nextbit Robin support ended on Aug 1st.
Guess I'm stuck with locked bootloader and no cell signal phone. Unless someone can help. One can always hope.
Anyway, thanks for reading.

If you bootloader is unlocked I think you can give a try to the Nextbit's Unbrick Tool
As you want to go back to stock , I think this is a good idea.
Now if your bootloader isn't unlocked there is unfortunately nothing I can do for you , unless you unlock it .
Edit #1: If your bootloader is locked , go to bootloader mode by pressing volume down + power button for about 20 seconds and try to see the bootloader state with fastboot commands. If it is unlocked , follow the process in the @nextbitKhang's thread .

Yes that's the main issue. Oem is Locked.
Is there any Oem unlock code i can use to unlock from ADB?

I don't think so ,I'm not sure, but I hope you'll find one.

On your Robin go to settings > system > about phone > tap build number until it shows developer options.
Go into developer options which is in settings > system > developer options.
Make sure OEM unlocking is enabled. (for good measure disable then re-enable)
Also make sure usb debugging is enabled. Have the Robin plugged into a computer so you can enable to pop-up on Robin asking for access for the computer.
Once they are both enabled shut down your phone. Turn it back on while pressing vol down+power and plugged into your computer.
In adb run command fastboot oem unlock

please i'm experiencing the same issue not on nextbit but on GIonee.
i have re-activate both OEM unlocking and USB debugging several times but it all void
same error: Remote: OEM unlock is not allowed
please kindly help

Downgrade from Pie to Oreo without Root and unlocked Bootloader?

Hey guys,
can someone tell me if it's possible to downgrade the stock android pie version to stock oreo without rooting my device or unlock the bootloader?
I read some threads and posts but i'm not sure, because the information is disputed.
So can i flash the old stock android without getting a brick or getting stuck in edl-mode?
Thank you for your answers

Hello,
I think that it's not possible without unlocking bootloader. The unique solution is to enter in edl-mode but this is more dangerous than unlock the bootloader. Unlock bootloader is very simple and not dangerous, you are just going to loose all of your data but with a backup this is not a problem.
Root is not necessary for that, if you need help to do your downgrade with bootloader unlocking tell me !
I'm here if you have any question or if you need help !

Flashing via EDL Mode only works with unlocked bootloader!
Unlock Bootloader will erasing all data (reset system)!

I don't now the link but I can explain you the process.
/!\ This will erase all of your data !!
1) Enable developer options by going to Settings > About Phone, scroll down to Build number and tap 5-7 times to enable developer option.
2) Once you enabled the Developer Options. Returned back to Settings > Developer Options > USB Debugging and OEM Unlock. Just Enable there options.
At that time you have 2 option, official option and non-official version.
- Official Version,
This method require some days because you have to ask xiaomi to send you an unlock code.
You need Windows it doesn't work on Linux.
1) Go to http://en.miui.com/unlock, click on Unlock button on the webpage now you have to login and then proceed to tap on Download Mi Unlock from the resulting page.
2) Now, proceed to put your Xiaomi Mi A2 Lite into Fastboot mode by powering it on while holding Volume Down and Power buttons simultaneously. Hold until you see your phone is booted into Fastboot mode.
3) After the successful login, the validation process will start on your phone, and for the first time, you will get a message that “You don’t have the permission to Unlock the device”
4) Now click on the “Go” button or use Go to MIUI Unlock page to receive the unlocking permission.
5) Now click on the Unlock Now and log in with your Mi account details and fill all details.
6) You will get OTP for confirmation use it to complete the process.
7) Now wait until your application gets approved, you will receive the OTP password on your phone number once it’s approved.
8) Now Open the Mi Flash tool click on unlock and pass the two pop-up. Your device will be unlocked
Non-Official but simple version :
1) Proceed to put your Xiaomi Mi A2 Lite into Fastboot mode by powering it on while holding Volume Down and Power buttons simultaneously. Hold until you see your phone is booted into Fastboot
mode.
4) Download Miniamal ADB and fastboot in you are on windows, https://forum.xda-developers.com/showthread.php?t=2317790
If you are on linux use
Code:
sudo apt-get install fastboot
Code:
sudo apt-get install adb
3) On Windows in Minimal ADB and fastboot or on Linux on the terminal enter this command
Code:
fastboot oem unlock
4) Your phone will reboot, it's unlock !

Locking Motorola Bootloader
Relocking Motorola Bootloaders can be difficult.
Don't relock the bootloader if it was unlocked by any other method than Offical.
ReFlash Stock Firmware, Factory Reset, Reboot. and make sure everything is working correctly before relocking.
Current locking instructions - 27 April 2021
You can't relock the bootloader without the stock firmware!! - Jun 1, 2020

[Guide] Flashing Motorola Firmware
After flashing Firmware, power up the phone to make sure it will boot.
If it starts up ok
return to bootloader and run
Code:
fastboot oem lock
Follow the instructions in your terminal's output.
You should see something like "signed system image required" which means you have to
Flash all system.img_sparsechunk.X parts a second time.
When finished run the lock command again and follow the instructions in your output line.
Continue until your bootloader is locked.
Other methods that have worked in the past
Run
Code:

If it cannot be unlocked. It maybe something like.
Code:
{"status_code":"0020","status_description":"Either there are errors in input data or this device does not have bootloader lock code available yet.","Boot_loader_unlock_code":null}
if you see
Code:

the link is not correct, try creating the link again.

Trouble unlocking bootloader? try this! by jbtumbleson

Just copied from link below
Setting lock/unlock properties​The ro.oem_unlock_supported property should be set at build time based on whether the device supports flashing unlock.
If the device suppports flashing unlock, set ro.oem_unlock_supported to 1.
If the device doesn't support flashing unlock, set ro.oem_unlock_supported to 0.
If the device supports flashing unlock, then the bootloader should indicate the lock status by setting the kernel command line variable androidboot.flash.locked to 1 if locked or 0 if unlocked.
For devices that support dm-verity, use ro.boot.verifiedbootstate to set the value of ro.boot.flash.locked to 0; this unlocks the bootloader if the verified boot state is orange.

Why is OEM unlocking greyed out/ unavailable?
It's not unusual for OEM unlocking on Moto devices, to be greyed out.
You need to connect to wifi/LTE and it should be available in 3 or so days after that.

Yes, Locking Moto Bootloaders is a mess.
Locking is actually more likely to cause a bricked device than unlocking.
The only advice I can give is the following
Follow the instructions in your terminal's output.
You should see something like "signed system image required" which means you have to
Flash all system.img_sparsechunk.X parts a second time.
When finished run the lock command again and follow the instructions in your output line.
Continue until your bootloader is locked.

Thank you. Since all I really want to do is restore deleted text pics and data, Is there any other way you might recommend that doesn't require an unlocked bootloader?

I have also read an article suggested to install TWRP and that the bootloader doesnt have to be unlocked in order to do it. Therefore , enabling root like capabilities. Any thoughts on this?
And another article saying that the Tracfones will unlock after 12 months and 1 day of service?

Question OEM unlocking T-Mobile

My unlocking is greyed out. Is there a way to get the bootloader unlocked? I really want to get a pixel style rom and get rid of T-Mobile crap

Technically you would want to SIM-unlock your phone first - this will enable the "OEM Unlock" toggle, but thanks to @Ju5t3nC4s3, you can skip that and, assuming you already have the unlock token from OnePlus, just do the following:
1. Run: adb shell pm disable-user com.qualcomm.qti.uim
2. Go to Developer Options and flip the OEM Unlock toggle
3. Now run: adb shell pm enable com.qualcomm.qti.uim
4. From now on the toggle will be disabled again, but now in "on" mode
5. Reboot to fastboot
6. Run: fastboot flash cust-unlock unlock_code.bin
7. Run: fastboot oem unlock
Keep in mind that unlocking the bootloader will factory reset the phone, so make sure you backup all the data from it before doing that.

Once u flip the switch u can easly get token needed to sumbmit to oneplus. What model do u have. Theres other ways to do it without having to get the unlock.bin from oneplus

I got my token from OP but even after installing it, I'm still SIM locked.
I can flash ROM's though.

Oem_Unlock will not sim unlock the device .

this is not working. I am using the tool and I got OEM unlocking toggled on and then re-greyed out in the on position. Not sure what to do next. Nothing seems to be working and there's no sounds in the video so I have no clue what's being done.

Is it true all of this is pointless because my SIM is not unlocked????

No, only T-Mobile can SIM-unlock your phone - you are probably getting error 255 right now when you try requesting a permanent unlock.
There is a strict requirement that phone must stay registered on T-Mobile's network for a few days (I think, three). Before that no one will be able to SIM-unlock your phone. After 3 days call T-Mobile support and ask nicely for SIM-unlock. They will probably tell you that you have to first pay-off your phone and wait 40 days. Ask even more nicely and give some reason. I used "I want to unlock this phone for development purposes".
It may take a few tries and pure luck to get to a rep that will be willing to help you.

Ok so for my question. Do I need to do this to unlock my bootloader and root? I thought that the all in one tool posted above didn't require that SIM be unlocked but I'm not seeing how because it's not working.

What exactly is not working?
Just get the latest platform tools and run those commands I mentioned earlier after enabling USB debugging. Worked for me even before I was able to SIM-unlock my phone.
If you're planning to use your phone with T-Mobile, it doesn't matter that your phone stays SIM-locked, but the most important part is to request unlock token from OnePlus, so if you haven't done so yet, do it ASAP - for some reason they don't send it to you right away, but wait exactly 7 days.
Here are the instructions: https://forum.xda-developers.com/t/how-to-unlock-the-t-mobile-bootloader.4256319/

I was able to get it to work up to the unlock token. Now I'm waiting on a response from Oneplus since Sunday.

I got my Tmobile Oneplus 9 Pro sim unlocked but it still shows my network locked and OEM is still grayed out. Any suggestions...?

How did u get the sim unlocked, sounds like you dont have it fully unlocked.

So I got my code and then got this, but my phone didn't reset?
op\unlock_code.bin
Sending 'cust-unlock' (0 KB) OKAY [ 0.000s]
Writing 'cust-unlock' (bootloader) Device is unlocked.
OKAY [ 0.016s]
Finished. Total time: 0.045s

NVM got it, was missing last command
