Taken from [Tutorial] Xperia S/P/U/Sola Bootloader Unlocking & Relocking and modified slightly for the ion. I take no credit for this tutorial.
Quick tutorial for unlocking & relocking the bootloader of the Xperia ion.
This is the official way to unlock bootloader
Warning!
This procedure will wipe the /data partition of your phone, so you will loose all ur stored data, settings. SDCARD will NOT BE WIPED!!!
DRM keys WILL be lost forever
Why should I unlock the bootloader?
You can flash custom ROMs/Kernels.
You don't need to worry if the new firmware can be rooted or not as with unlocked bootloader you can always ROOT your device.
SE/Sony gives sneak-peaks/preview builds of latest OS which requires unlocked bootloaders, as they did with Xperia 2011 line (they had ICS alpha/beta), so who knows may be SE/Sony may give early builds of ICS (JellyBean???)
Most of this is taken from lollylost100's his tutorial from ARC thread (all credits for that concise tutorial go to him, i have elaborated on a few things and added device specific changes)
[ Before we begin unlocking bootloader ]
Get the IMEI code for your device: type *#06# in phone dialer to find it out, note only the digits (no dashes)
Download the fastboot package with usb drivers (alternate drivers if the ones in package dont work)
Make sure u have a windows PC with USB cable to connect the phone
Power down your phone and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows will start driver installation, extract the above package and point the driver install to that location (usb_driver) folder
Once drivers are installed just disconnect cable and power on device
[ how to unlock ] (official way)
Go to: http://unlockbootloader.sonymobile.com/ and read everything!
At the bottom click 'Start Unlocking the Bootloader'
First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the phone dial pad and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

After you have verified that you can unlock bootloader, scroll to the bottom of the page and click "Continue"
You will get "Are you sure prompt" accept it by clicking "yes i am sure" (i assume that you have read an understood it)
Then accept the "legal terms"
Finally you will get a "Create Unlock request" page, enter your IMEI (sometimes the last digit needs to be removed for this to work), name and email address
You should now receive your unique unlock key, its displayed on screen, SAVE THIS KEY SAFELY
Extract fastboot_with_Android_USB_file.rar and open fastboot folder
Hold SHIFT and right click on the background of the folder
Select 'Open command window here'
Connect your phone in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above)
In the cmd windows type in fastboot.exe -i 0x0fce getvar version
If a value is returned (it will return 0.5), it means the phone is correctly connected
Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which you received earlier.
Your device should now be bootloader unlocked
If this tutorial is too much for you then itskapil wrote a step-by-step guide (and recorded a video also):
-Instructions: http://www.theandroidsoul.com/how-to...-play-neo-pro/
-Video: http://www.youtube.com/watch?v=LRH3pC7MhEA
(the above videos and some steps are for Xperia 2011 devices, but most the steps are same for Xperia ion)
Info on Relocking bootloader is in next post
Relocking bootloader
RELOCKING BOOTLOADER WILL ALLOW YOU TO GET NEWEST UPDATES & REPAIR DEVICE USING SEUS/PCC
Before we begin relocking the bootloader make sure that u have flashtool download & installed
You can get the latest version of FlashTool from:
http://androxyde.github.com/Flashtool/
Download link is under "Installation" tab
If you have not use FlashTool before read this thread:
http://forum.xda-developers.com/showthread.php?t=1526866
Download this FTF:
Xperia ion -> LT28-ION_Relock_bootloader_Dogsly-TEST.ftf // Mirror 1
Flash this FTF via FlashTool:
When it says enter flashmode, power down device and keeping VOLUME DOWN button pressed connect usb cable to phone, the device will now enter flashmode (green LED)
After this file is flashed reboot phone
Bootloader will now be relocked!!!
Incase device doesn't boot DO NOT PANIC... You can flash stock firmware FTF anytime to get back to stock ROM
P.S.: there is no official way to relock bootloader
So because my phone says I can't unlock the bootloader, does that mean I can never unlock the bootloader? Or do I have to wait to be able to root it first?
PS: I got my ion from Best Buy so is that why? Will I ever be able to unlock the BL ? I've rooted and unlocked my x10, back in the old days lol but I'm just wondering if there's any difference with getting a phone from at&t directly or from the sony store and best buy.

Have to wait to see if another way to unlock the bootloader is discovered. Root and unlocking the bootloader are two different things that accomplish or allow different things you can do on the phone.
IE rooting allows you to uninstall system apps & bloatware, backup apps/data, make changes to build.prop etc. Unlocking the bootloader will give you access to fastboot so you can flash custom roms/kernels and other images such as a pre-rooted system image to gain root.
I wonder. If we can not unlock the bootloader for some LT28at, why is there a key to unlock it? I did the Sony bootloader unlock for fun and apparently they have a key for my LT28at even though it says bootloader unlock is not allowed.

I understand that works for lt28i but I'm referring to lt28at the us model of the ion and why there is a bootlloader unlock code when we can't unlock it.
see if it works
Has anyone with an ion that has
Bootloader unlock allowed says Yes

tried to unlock it via the sony site and if you did and it was successful have you tried to relock it using the file linked above? Would be nice to know if that works.
Possible fix?
If the LT28i can be unlocked, what if we flash the international firmware on our LT28at's and then do the LT28i method? Maybe a stupid question but this is the first phone I've had that's a challenge to do stuff like unlocking and rooting. My last phone (HTC Aria) was extremely easy.

Flashing firmwares does not change the ability to unlock the bootloader.

Kinda figured that
I tried to relock the bootloader. The flash pass but the phone can't turn on after that.
*I reflash the stock kernel again and the phone can power on now.
So here is the result, once you relock bootloader, you need to flash back the stock kernel in other to turn on the phone. Hopefully this will help those people who got stuck after relock bootloader.
Hello guys
I was just wondering, if bootloader unlock or flashing cutom kernel will allow to use sim cards from other mobile operators (European for ex.) ?
I have an ability to buy this device in us through my friend. but Im interested if I would be able to use it in Europe I was thinking of buying xperia p or s, but they dont have microsd card support.
Im not interested in using LTE networks. Just common 2g.
I planning to use it like a second android device as a multimedia player instead of my galaxy s wifi5.0. (because of good sound quality and other features).
Thanx a lot for responses

No. You can't unlock the bootloader of the lt28at and you can't sim unlock it either. Best bet is get an international version not one from the US.

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.

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

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.

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.

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.

Sent from my LT28i using XDA Free mobile app
Hello.
I've searched forums and found some threads like this but my problem is a bit like them and a little bit different at the same time.
Sorry for my ENGRISH
I have Sony Ericsson Arc S, (LT18i). My brother bought it from UK and bringed to me, to Türkiye (Turkey). As you guessed, Turkish simcards didn't work and my brother gave money to a mobile phone seller to unlock it's simlock. After this, we able to use phone with Turkish simcards in Turkey.
The other day, after a couple years, I wanted to install a custom ROM on my Arc S.
This is how everything started.
I searched XDA forums and took notes. How can I do it, which programs needed etc.
Preparing
First, I did a factory reset.
After the phone opened, I changed usb connection to MSC, allowed Unknown sources and opened USB debugging.
I installed Flashtool 0.9.10.0. I readed a couple posts about that, previous versions gives no errors.
Under /drivers folder I found a driver package. Installed it with just Flashmode, Fastboot and Sony Ericsson Arc drivers selected.
Pluged in my phone and checked if it's drivers installed or not. Success. I can see my phone in device manager.
Installing
I readed a few guides and they say I have to Unlock bootloader. So I clicked Bootloader Unlock option in Flashtool. Followed the instructions, gone into flashmode, restart, gone into fastmode with pressing menu button and plugging the usb cable etc. There was a window with my IMEI and I followed the instructions and I get a code (long, including letters and numbers) from official sony website. I entered this code to that window and it said my bootloader is unlocked.
After that, I rooted the device. No errors.
Installed CWM via Flashtool. No errors as far as I remember.
AND THIS: Flashing a ROM. I found an Android 5.0.1 ROM and it said that I had to flash boot.img. So I did. I mean, I tried. I GOT ERROR. And, BUM. Something happened and I couldn't open the phone.
After a search, I found a solution says using Sony Companion may restore the phone. I tried this. Follow the instructions and my phone opened with ICS 4.0.4 instead of old version, 2.3. And now, it says, INSERT THE SIM CARD.
I searched the forums about 2 days and didn't find a solution to this. It ignores my sim card. Then, I saw a secret code about simlock and bootloader status and entered that code *#*#7378423#*#*
Under Simlock option,
They say there must be X's. At least the first one must have X on simlock screen but it hasn't. And there are all 0's. No X's, and zeros. So this is bad i think.
Under Configuration
In configuration section, it says Bootloader Unlock Allowed: No. As far as I learned from XDA forums, that means bootloader is locked again. Because it must be unlocked or unlock allowed: yes.
So i tried to unlock bootloader again. I had no idea what I've done. First, it said go flashmode. Done. And it said go into Fastboot. I couldn't. No Blue LED.
You see the thing? => Flashtools says go Fastboot to run Bootloader unlocker. I can't. Forums says I have to bootlocker unlock to enter fastboot. Bootloader unlock to enter fastboot. But enter fastboot to boot unlock. Wow.
Lastly, I tried flashing custom TFT's to see if it can flash or not. IT FLASHED. I can flash STOCK TFT's, even a KERNEL i downloaded from here. I can Root, install Busybox ( I don't know what is it haha), Install CWM 5.0.
But since it can't see my Sim Card, i didn't try to install custom ROM.
What I have to do? How can I unlock to simcard lock if it's locked? is my bootloader locked?
My brain hurts.
I wrote all things because it's easy to solve a problem with more information. So a few things more:
I use Windows 10.
I didn't use original cable at first. But you know, no errors now. It's not important at this point I think.
I unistalled mobile device from devices manager and delete the driver. I installed inf file from sony website and selected it for ADB driver. It says now Sony sa01102 ADB Interface Driver. If Fastboot needs correct drivers, I installed from it's official site, offical one.
I didn't tried another computer because again; no errors from Flashtool.
THANK YOU ALL.
I maybe copy this to other websites.
About Loader.sin Error
I did get Loader.sin Error a few times. But when I use previous Flashtool version, there was no loader.sin error.
"In configuration section, it says Bootloader Unlock Allowed: No. As far as I learned from XDA forums, that means bootloader is locked again. Because it must be unlocked or unlock allowed: yes." It means you cannot unlock bootloader! Its not possible , your phone is locked , i mean you cant run fastboot mode , its locked , install stock firmware and thats all , you cant install any custom firmwares as Cyanogenmod or custom kernel anymore. If you can't understand it sorry because english is not my main language.
Hi there guys! I've got Xperia Z5 Premium (as far as my PC recognize it as such).
It is probbably with locked bootloader, cuz in fastboot it gives me error : <remote:failed command not allowed>
BUT i do not have access to the menu. I found the phone in one mountain near a hut, so far i decidet to try flashing it, but it seems bootloader is locked. Phone is locked also with pin code.
The usual methods i found need IMEI, which i do not have. If i open it, is tehre IMEI number ?
Is there any way to flash it or get the IMEI?
PLS guys, don't bother ****talking about stolen device or such... If anyone recognize it, come and get it.
SOLUTION that worked for me : https://forum.xda-developers.com/z5-premium/general/how-to-tottaly-unlock-xperia-z5-premium-t3585640
if you have find that device in a hut. its probably better to return to authorities! the owner might have valuable data in it! atleast try tracking down the owner!
however you can still flash the device via FLASHTOOL using flashmode / original STOCKROM only and you can keep the data also alive by just excluding wipes in the flash firmware area.
once booted try to find the owner info and return the device!
i
Hi. I work in that hut, it is in ski resort, so you can imagine how many people are going thru there. 2 months, phone was ON and connected to WiFi. No sign that someone is looking for it.
There is no owner info on the lock screen, so.... And where i live, authorities are worst than thiefs, so, that is not an option. As there is no IMEI or other info on the phone itself, i think it is unable to find the owner! Also it is foreign sim card in it, but noone calls or text.
EDIT: I've used both flashtool and fastboot, but no success. In flashtool it says "Your phone bootloader cannot be officially unlocked" , in fastboot > Failed(remote:command not allowed)
So, is this a one nice BRICK with clock on it ?!
Isn't there any way to force flash or unlock screen or bootloader ?!

Hi. I work in that hut, it is in ski resort, so you can imagine how many people are going thru there. 2 months, phone was ON and connected to WiFi. No sign that someone is looking for it.
There is no owner info on the lock screen, so.... And where i live, authorities are worst than thiefs, so, that is not an option. As there is no IMEI or other info on the phone itself, i think it is unable to find the owner! Also it is foreign sim card in it, but noone calls or text.

you cannot just simply unlock the bootloader like that. you have to request SONY to send you unique keys and these used as password in order to unlock you bootloader! ( i.e. if the device is NOT SIMLOCKED from the origin country)
-- unlocking bootloader means LOOSING your DRMKEY/TA BACKUPS ,
please make your self aware of all the circumstances!
I have key to unlock bootloader from SONY. May be option in phone menu is restricted so this stop apps from flashing :/
I know about all circumstances.
So far i've flashed OEM rom, but now it ask for google account that was previously used on that phone, which is annoyng. Sony is copying apple or what ? Wtf happen with our android devices

it will remain mystery to me that how did you manage to have imei number of the device while phone was locked---- anyways
while device is open , goto dialer and dial *#*#7378423#*# then goto service info >>> Configuration and check "BOOTLOADER UNLOCK ALLOWED:" if it says NO then sorry, this device cannot be BOOT UNLOCKED. better to return it!
the previous google account prompt is because the old user data is intact. perform CLEAN FLASH , wipe EVERYTHING. (just tick the boxes as shown in the image (FLASHTOOL FLASHMODE , FIRMWARE SELECTED)
and a Big NO to sony copying Apple. and nothing happend to android devices! you can have easy go devices like huawei/lenovo/alcatel/(even samsung) etc. their stockrom can easily be xploited and kingroot supports various of devices under those brands. however Kingroot removed SONY from their website after Android 5.1 since they could not bypass SonyRIC from Android 6
I've got imei thru Flashtool, Emma, there it showed me Imei number.
This option with the code in dialer may be usefull with older android version, now it is unable to use it thru emergency call, since i do not have access to dialer itself.
I performed clean OEM flash thru Flashtool, wipe everything, but account lock is still there.
I do not know where to return it! It is foreign phone. I wait 2 months for someone to call or look for it. I work in ski resort and almost every day someone found lost phone. If i return it to police, they ouldn' do anything about it. Will sell it for 20euro probbably. I have friend in police department so i know what is going in there.

I've flashed absolutely everything, wiped whole data, but Account lock is still there. I tried with older android, and the BUG that allows me to download app from internet is working , but i can't find way to install bypass app. As soon as i click on APK it send me to chrome screen. Any other ideas ?
Just finished with the bypass of FRP.

the startup screen first time always ask many questions about you in order to personalize your device. you can skip many of them including google account
but i am talking about fresh start. any other old user data will always ask you credentials
