[Q] Bootloader unlock problem

So I followed the bootloader unlock directions but at the end when I enter fastboot.exe -i 0x0fce oem unlock 0x(My Key Here) it comes back:
Failed (remote: Command not allowed)
Using the previous "getvar version" line it seems like my phone is connected properly. What can I do to solve this?
Thanks!

First you need to be sure if you can unlock the bootloader or not but checking the service info.
If i remember correctly i think you have to remove one number from your key.

Yeah, I got the key from unlockbootloader.sonymobile.com. As you said, I had to discard the last digit to make it 14 characters, but the code was sent to me all the same. I'm not sure that's the issue though

Do you have bootloader unlock status= yes in service menu?
Maybe you have succeeded the unlock process,try to root it now.

Sorry, this was the problem alright. Bootloader unlock status is no. I should have checked, thanks for the help.

[Q] oem unlock faiil

hi
i try to unlock bootloader (xperia t)
but i got this error:
(bootloader) unlock phone requested
FAILED (remote: oem unlock failed!)
----the code sony dev. sent me:AE926322281A50B3- some people say this code is wrong and it should be All numbers. i did't understand what to do
please help me

the code for my previous phone which was a xperia play was numbers and letters. i don't know about t because i have bootloader unlock allowed no. also check through service menu if your phone says bootloader unlock allowed yes or no
Sent from my LT30p using XDA Premium 4 mobile app

just checked as i still have the email with my unlock code and it contains both letters and numbers and i know mine worked
are you following all the steps correctly got all the drivers etc you need installed on your pc?
i have unlocked a few xperia devices and the T was the easiest for me i remember unlocking my arc s had to remove the battery then remove a little piece of plastic and connect two "dots" together with a paperclip (was the easiest thing to use i had at the time)
the T was simply following a set of instructions that didn't require a vast amount of user work from what i remember
go back to the start of the instructions and follow them step by step make sure you have all the needed drivers and softwares etc installed

that was the testpoint method for the arc s. the only reason it was done so you don't lose drm keys

it also meant you could unlock an non unlockable bootloader (mine was locked and also network locked) i was merely saying that the T is relativly easy to unlock (if it allowed on the device) as long as you follow all the instructions and dont miss out what appears a tiny step

check your imei number just wrong coz some do not unlock

Xperia Z1 Boot Loader Unlock Problem

Hi.
I have been having problems trying to unlock the boot loader on my Z1.
I followed the instructions provided by Sony to unlock. I had previously unlocked and relocked the device.
However now when following instructions again I am given the following errors:
FAILED (remote: Command did not succeed)
And after this,
FAILED (remote: Device is already rooted)
Even though it is not and service menu says,
Boot Loader Unlock Allowed: Yes
Any help is appreciated.
Thanks.

This is a common issue after Relock Bootlader. I saw many users complain about that. They Unlocked the Bootloader and then for some reasons they relocked it, then again they try to unlock it without success. I think you can unlock only 1 time the bootloader or you relocked and something is missing.

Then is like I said but I don't know where is the solution and if you can unlock it again.

So your saying you can only unlock once?

I am not sure but unlocking, relocking, unlocking some pieces is missed and now you have this problem. I hope someone know where is the problem. Check Bootloader Unlocking thread.

I had no problems with relocking and unlocking BL. Used flashtool for it.

I unlocked on a none branded ROM the first time but now running a branded firmware for Three in UK as you can only access 4g using their firmware as only software update allows access not a sim card change.
Could this be the problem?

Hey guys last days im started looking how unlock my c6602 and i cant find any way that work for me
I tried doomlord way and didnt worked what i did:
1-Got my bootloader key from sony
2-connected my phone in fastboot mode to my pc
3-opend command window in the place i installed fastboot drivers
4-typed: FASTBOOT.EXE -I 0X0FCE GETVAR VERSION then enter i got VERSION:0.5
5-typed:FASTBOOT.EXE -I 0X0FCE OEM UNLOCK 0X************
6-i got that error :invalit id (0x**************)
I checked the number many times and it was currect SO WHY???
I tried flashtool to unlock and i got that (failed remote: command did not success)
Is sevice menu says bootloader unlock allowed: yes
Is there any solution for that??
Running:4.3 stock %100
EDIT: today tried again in command window AND NOW EVERY TIME I THY THAT SAYS failed remote: command did not success)!!!!!:crying:

I said this to you when you asked in the bootloader unlock thread, but you didn't respond or acknowledge my reply.
The unlock key is case sensitive. Meaning that any letters that are upper case (capital letters) must be entered in upper case. So E must be entered as E, not e.
If you don't enter the unlock key exactly how they sent it to you, it will not work.
If it still won't work, maybe you entered your IMEI incorrectly when requesting the unlock key. Try requesting it again and double check the IMEI when you enter it into the form, as a key generated for the incorrect IMEI also will not work.

Is there any one click to unlock?

And also when i request me key i put my full IMEI and click ok and its says YOUR IMei is incurrect (try delete the last charecter) is thats may the problem?
Anyway i bored of that unlocking story now im trying to get perooted rom

Well, you're definitely doing something wrong. Both Flashtool and fastboot work for unlocking the bootloader for everyone else.
From your screenshot in the bootloader unlock thread, you were entering the key with all lower case characters, which was probably wrong if you're now entering some upper case characters. Enter it EXACTLY how it is in the email.
Anyway, good luck flashing any rom without root. You'll need root to install a recovery.

Are you deliberately not reading what I'm telling you or something?
You'll need root to install a recovery to flash that rom. If you don't want to unlock your bootloader, you will need to downgrade to a 4.2.2 stock rom.

I tried it on 4.3 and 4.2. The bootloader unlock allowed says yes.
Please help

Can't unlock bootloader

Ever since I re-locked my bootloader it has never wanted to unlock again.
The first time I unlocked my bootloader was on 10.4.1.B.101 (i think). I flashed VanirAOSP and it worked fine. I cracked my screen later on so I locked bootloader and flashed stock to send it in for repairs. All was fine.
Yesterday I attempted to unlock once again, but this time on the latest 4.4.2 stock rom (not rooted)
Bootloader unlock allowed: Yes
All was good so far.
I used fastboot.exe -i 0x0fce getvar version to see if the device was attached properly.
*Bear in mind I have not re-installed Windows or install/uninstall drivers for any of my Android devices.
It returned 0.5 so I proceeded to unlock the bootloader using fastboot.exe -i 0x0fce oem unlock 0xKEY
It said FAILED (remote: Command did not succeed)
I used the same command again and it did "..." for a few seconds and said OKAY
I unplugged my XZ and rebooted it and it bootlooped forever.
I have since restored with PC Companion and rooted with Towelroot. Really missing AOSP so does anyone have any suggestions as to how I can fix this?

Did you check the imei and the unlock key?

I'm not stalking you, for some reason this thread keeps showing up at the top of my Tapatalk feed ._.
Heard some people changed 0x0fce to 0x0FCE and it worked for them.

Just use only "fastboot oem unlock 0xKEY"

Neither of those worked.

Worst case scenario it could be dead eMMC. Dunno then.

Try to downgrade to 4.2.2 and unlock. And to update just flash any stock based rom or custom rom

I wiped everything and flashed 4.2.2 and it still did Failed: command did not succeed
I haven't tried with Flashtool yet but it shows that the bootloader is rootable.

Note that the KEY must be typed without last 2-4 digits (can't remember exactly).

Okay I've successfully unlocked the bootloader and flashed recovery using Flashtool.
I made an ulcode.txt in custom/mydevices/SERIALNUMBER and put my unlock code in the .txt
Opened flashtool, picked BLU and held vol down and plugged the usb cable into the phone.
I pressed Unlock and away it went and it completed.
After un-plugging I booted it up and my data hadn't been wiped and upon going into the Service Menu it shows that the BL is unlocked.
Hopefully this helps anyone else whos having troubles
