Hello all,
I've got an Arc S that I've been trying to unlock the bootloader on using Sony's method, without success.
1. I have fastboot and adb installed on my machine (Linux Mint 14 32bit)
2. I've pulled the unlock code from Sony's website
3. I set my udev rules as laid out in this tutorial.
4. I have checked my bootloader to confirm that it can be unlocked (and currently is locked)
5. Fastboot is working (When I type in sudo fastboot devices, I get a hexadecimal string in response)
6. However, when I try to unlock, it always fails.
Initially, it gave me a "oem unlock failure code". After I rebooted thought, the code changed. Instead of something like this
Code:
oem unlock failed!
it gave me this
Code:
...
and did nothing. I let it sit for a few minutes and then forcibly shut down terminal, no damage done to the phone.
I'm quite confused at this point. From all my google searching I can't figure out why the booloader won't unlock. I'm pretty sure that I have the right unlock code.
A second and curious thing that may or may not be related is that the phone is rooted, but when I tried to transfer CWM via fastboot it threw an error, saying that the phone needed to be rooted first. However, it is rooted and apps such as Titanium Backup work just fine, verifying the root. Can anyone give me some direction on this?
I know there is a video on the how to unlock lt18i bootloader. It also has step by step process on fixing issues for unlocking bootloader. Lemme get.it for ya.

May be a relatively simple thing. Is your phone simlocked? This may have some bearing on it.

I don't believe that it is simlocked. I don't believe the phone was purchased through a carrier. For clarification, this is a friend's phone so I would need to ask them as to where they purchased it.

No, it is not simlocked, else it would not show Bootloader Unlock Allowed: Yes
To OP: Write out the command you used to unlock the bootloader.

As taken from the Cyanogenmod Wiki page for Anzu devices:
Code:
fastboot -i 0x0fce oem unlock 0xKEY
where KEY was the bootloader unlock I received from Sony.
The dots indicate the software's not detecting your device. I had the same problem. Try reinstalling the drivers. If it still fails, maybe you can give the method outlined in the link below a go. It's for the relatively newer Sony devices, but maybe it'd work with the Arc. I haven't personally tried unlocking via Flashtool, but for me, the Fastboot command-based experience hasn't been all too good. I now use the Fastboot option in Flashtool, as opposed to standalone Fastboot, to flash every kernel that I use. Works like a charm each time, and what's more, it does away with the need to key in commands in the exact syntax.

I tried unlocking the bootloader via Flashtool and I got the same result of
Code:
oem unlock failed!
. So that means that something is wrong with my fastboot installation (not likely)my udev rules(possible) or for some crazy reason the phone is not reporting back correctly. A curious thing I noted is that when the phone is detected via adb it doesn't return the phone's IMEI. It does return a number, but it does not match the IMEI. Has anyone ever heard of that situation?

I don't believe Fastboot returns the phone's IMEI. It's always looked to me like a random number that's generated to show successful connectivity between the device and the Fastboot program. But then again, I could be wrong.
Anways, despite the message you got, it's looking increasingly likely that your bootloader cannot be unlocked.
PS: You retired your SGS III, but kept your Arc? The decision really befuddles me.

After much research I've found that when you get the "remote: oem unlock failed!" message it means you've enter an incorrect unlock code. Thing is, I know that I have entered the IMEI correctly on Sony's website, so I'm stumped there. I tried this setup in windows and got the same result, so I don't think it's fastboot or drivers anymore. It makes me wonder why I would be getting an incorrect unlock code...
To answer your PS, this phone belongs to a friend of my whom I'm doing a favor for. Note I don't have the Arc S in my sig. My retired SIII went to my wife, who was quite happy to have it.

Are you sure that you left out the LAST number of the IMEI, when entering it on the website? You need to do that, else you get invalid code.

Yup, that I have. I originally entered the 15 digit code and the website threw an error, so I deleted the last digit to get the unlock code that I tried.
same issue as LT26ii
Well I have exactly the same issue at my Xperia SL LT26ii, it just shows "oem unlock failed", do anyone know how to fix this ?

oem unlock failed
Problem solved!
Hey guys, I just unlocked my LT26ii after many times of "oem unlock failed". Here's my solution:
0. well first just remember your IMEI code, cause later it will changed.
1. Download a new firmware in ftf format.
2. Update firmware with Flashtool.
3. Turn on your phone and get you imei code. Now you should got a new one different from the previous one.
4. Use the NEW imei to unlock your phone.
Good Luck !
PS: dont guarantee that worked but if it does please let'me know.
Good Afternoon,
I want to install cyanogenmod 10.1 on my xperia arc S. tried to follow a tutorial, but when it came to the part of booting the device in recovery mode I found that my bootloader was locked. Apparently, on the Rooting Status it says: bootloader unlock allowed: NO. So, my question is, what should I do in order to unlock the bootloader and install the cyanogenmod. thank you vm for your time.

I too have a Sony Ericsson (pro) with bootloader unlock allowed: NO. I've scoured the Web and only come up with this site http://www.wotanserver.com/en/sony-ericsson/xperia-pro-mk16/unlock-tool/debranding-flash
Which claims that if I pay 7.99 euros I'll be able to unlock my bootloader. My question is what am I paying 7.99 for? What does this service give that can't be found out for free?

i dont be rude bro, but i had this situatzion atleast over 20 times here with friends or others from my country (then i done the job over teamviewer lol, what a pain in ass)
theres a simple calcultion which allways was right for me:
- service menu says: bootloader unlocked allowed: YES [x] (check:good
- installed all the drivers & stuff properly
(you say that cmd tells you device is connetced, so [x](check:good
if its then still not working, ITS 100%:
a human (your) fault.
- maybe request wrong code (99%)
- ???
i say that because i have friends which telled me same thing. they said "i read it thrice & requested code more than 5 times...... bla bla" - & those a were mostly smart people. (no n00bs)
guess what, after triyng help them for hours (!) over internet, i go to them next day & unlocked phone in 5 mins. lol
i dont know what they doing wrong. or why its not working. i only know if you do it carefully,patiently, read all & DO IT EXACTLY like stated it allways works. because its my way & it allways worked (even they say they done it same.)
but keep in mind that maybe your carrier locked it in some way. here in my country its not allowed for carriers. but idk how its in yr country

When I unlocked my bootloader about a year ago.... I used the Official Sony Bootloader Unlock method and it worked for me. If you haven't found it already, then you can find it here ( http://developer.sonymobile.com/unlockbootloader/ ). Some people also say that they used Flashtool to unlock the bootloader, so you might give that a try if you'd prefer that to the official Sony method.
I saved the bootloader unlock instructions that I used last year from the Sony website, and there was one important step to pay close attention to-- When going through the steps to request the unlock key from Sony, it said - "Enter your name, a valid email address and the first 14 digits of your device’s IMEI or MEID or IDID number (remove the last digit if necessary). Click submit." It was important to only enter the 1st 14 characters of the IMEI when submitting for the unlock key... Also, I read in some other XDA posts that you need to make sure that you use all CAPS on any letters that might be in the IMEI code...as it apparently can cause you to get a bad unlock code if you don't use all CAPS. After you submit this to Sony, they will email you the unlock key.
The last step of the Official Sony Method says: "... If you still want to unlock the bootloader of your device, enter the command *fastboot.exe -i 0x0fce oem unlock 0xKEY, where KEY is the unlock bootloader key that you got in the beginning of this instruction. The bootloader should now be successfully unlocked." Make sure you are copying the fastboot commands exactly... including the lower case x that comes right before your unlock key.
You may want to try to go through the steps again with the Sony Website to see if you get a different unlock key by trying the above tips. Then try to use the Official Sony method to unlock the bootloader, or try Flashtool to see if that will work.

It doesn't show the unlock has been tampered. lol. It shows your phone has been tampered with (unlocked your bootloader) and also shows on a different line that your bootloader has been relocked.
You need to unlock it like the first time. Go to the HTC dev site and get the unlock code. I would try to run the first one I got again first if you still have it in your email.

Hi all, I need to relock the bootloader, flashing back stock MM or LP didn't solve the issue for me, neither hard resetting, bootloader is still unlocked and the message appears on every start in the high left corner.

Did you use the proper fastboot.exe? What OS is your computer? If it's windows try these.
It seems that in order to get fastboot operational, you need to have a working bootloader. So, after a couple (hundred) of tries - DO NOT FLASH KDZ (REFURBISH) your LG G4, it still boots once in a while and if it has your account and data and it will be faster to get to fastboot mode and get the bootloader locked again. Can somebody confirm that you can execute "fastboot oem lock" on an unlocked device? This will save us a lot of time trying to get the device to that state...
for me it is impossibile. If you have a g4 with bootloader locked and you doing fastboot oem unlock it says that it is no possibile...you must follow the instructions that lg provides with file unlock.bin
So is impossibile relock bootloader with fastboot oem lock...I hope that anyone find the way to do it...
Well unfortunately it is not posible to lock the bootloader via "fastboot oem lock" I'm waiting for user @warloxfre for some more info on his ideas (fingerscrossed)
