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.

You can unlock bootloader on the LT28i and, accordingly, there is a file to be relock bootloader LT28i

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.

I think you can switch the rom to international version but it will still be bootloader locked. Not sure about carrier

Hi guys,
First post on this forum, so I apologize in advance if this is not the right section. I have an Xperia E phone and I'm following a guide I found on the net to install Cyanogenmod in it. In order to do it, I followed the official Sony guide to unlock the bootloader, they sent me the unlock code and I used fastboot to enter the code into the phone. After that, the phone got stuck in a bootloop and I had to use a program called Flashtool in order to flash the original ROM into the phone again.
Now, when I enter *#*#7378423#*#* on the phone's dial pad and go to "Service info > Configuration", I can see the following message:
Code:
Rooting status:
Bootloader unlock: Yes
:
The weird thing is every guide I've read on the net about unlocking Xperia devices claim the above message should be "Bootloader unlocked: Yes", so I'm slightly confused (note the difference between "unlock" in the above message and "unlocked"). I guess it is actually unlocked because I was able to use Sony's Flashtool to flash the original ROM, but some clarification on this would be useful since I'm planning to install Cyanogenmod and I wouldn't like to brick the phone by flashing a custom ROM on an unlocked phone.
Thanks in advance for any help!
I finally was able to install CM11 in the phone, so I guess the bootloader was unlocked after all. Now I'm having a couple of issues, but I'll open a new thread for that, since it's a different problem.
Regards.
Hello guys, sorry because may be this is the 50th time someone ask this question but the situation change every day. Yesterday I won from lottery and decide to go from G3 to G4. My model is European H815, I want to ask you can I root G4, change the recovery and e.t.c. without unlocking the bootloader? And also if I unlocked it is their any way to locked it again or to use my warranty? Thank you!!
well you can only root using low effort root(google it or find it here ) But to change recovery you have to unlock bootloader
No there is no way confirmed to relock your bootloader
GOOD LUCK
Thank you! If I root by this way and download Flashify and try to change recover what will happen ? Thank you!
without bootloader unlocked nothing will chnage ( recovery wont be installed ) and when you reboot your phone it will get u error (authentication error #9) as i remember and you will have to flash new firmware using lg flash tool 2014 so i dont recommend you do so
if u wanna change recovery unlock ur bootloader
you are welcome anytime
I did not get it, I hope you can light me up:
1. Doing root using low effort root means rooting without unlocking bootloader? (because I flew over the thread and did not read anything about it)
2. If I do unlock Marshmallow's bootloader, what happens when I downgrade to Lollipop via flashing proper KDZ? (I would guess that the unlocked bootlader will be overwritten!? So flashing Marshmallow again would end up in a locked bootloader, doesn't it?)
thanks
You can root lollipop without unlocking bootloader but with marshmalow you can't, you have to unlock the bootloader.
You need an unlocked bootloader for custom recovery.
Bootloader unlocking is a one way operation , you can't go back.
Once we're able to get bootloader unlock key using DC unlocker , for how much time the key will remain valid to unlock bootloader for later time ?
I am planning to unlock bootloader later but want to get the key in advance.
1) If there is any sort of expiry data for requested bootloader key ?
2) Can same key can be used again after using it for 1 time ? In case if bootloader gets relocked , how to unlock again ? Do we again have to pay DC unlocker for bootloader key ?
1) each bootloader code is permanent, it wont expire.
2)you use the same bootloader code to unlock if your device is relocked.
I unlocked my bootloader with dc unlocked, but couldn't get a recovery,I installed one but it was stuck on twrp logo,please provide me a working link

Hey thanks for clarification , but wanted to confirm again . Are you 100% sure ?
Cause i asked Indian customer service of huawei and the female representative said opposite for 2nd point , said have to request again , though she sounds very amateur and dumb to provide knowledge regarding bootloader.
Does this one bootloader key remains same for every intentional market ?
I entered my device info (European G8s) on the LG bootloader unlock page and they actually sent me a key
I flashed it and the bootloader is now unlocked.
Are there any custom recoveries for the G8 so I can root it?

You can root without twrp in fastboot. No custom ROMs because most people can't unlock bl...
Just tried with my LMG820QM. Does not work. I was hoping it would because the G8s isn't on the list either.
Thank you.
If anyone has the stock boot.img of the EAUW (I think? the one with W) variant, please upload it
I can't manage to unpack the KDZ and get to the img but I would really love to get root already

Anybody with unlocked bootloader already tried to flash a gsi?
According to the G8, v50 telegram group gsi are fully working on the g8 without any special adaptions.
Anyone know how to unlock the LM-G850QM version?
Can't seem to find a way yet.
How do you lock the bootloader?
I bought an unlocked LG G8 ThinQ US Cellular version here in HK. Works perfectly fine but I receive the bootloader is unlocked message when loading up. As a result (or at least I think it's linked), when I try and install any banking app for Citibank on my phone, it insists my phone is rooted and I cannot use it. I have checked with as many different apps as possible and they all insist that the phone is not rooted. I don't need/want the phone to be rooted and I want the banking app to work on my phone, so I am trying to lock the bootloader. Apparently, this is doable using ADB and loading in fastboot, unfortunately, I cannot load the phone into fastboot mode. Any ideas on how I can lock the bootloader as it's not clear how it was unlocked in the first place? The version I have is LMT600US.
Also, if anyone knows whether locking the bootloader will somehow render my phone unusable - that would also be helpful as I clearly don't want to do that? :good:

Well, you can first try to install magisk manager and try to enable magisk hide (the default settings for play services and for your banking apps). If it says you don't have magisk, make sure you try and backup your boot img first and then click direct install. You can also hide magisk manager in settings. If you still don't pass safety net, clear data for Google apps and look up the pxl4xlprops module
I have an LM-G810EAW with Android 10 (V20a-EEA-XX) and tried to unlock the bootloader. Got unlock.bin from LG and tried to flash it, but got the message:
Code:

Sending 'unlock' (1 KB) OKAY [ 0.009s]
Writing 'unlock' FAILED (remote: 'Flashing Unlock is not allowed')

Have I missed something?
