Xperia ion Bootloader Unlocking & Relocking

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.

Click to collapse
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.

Then your bootloader isn't unlocked.

Keypad, type in *#*#7378423#*#*, Service Info, Configuration
If you see this
Code:
Bootloader unlocked: Yes
or this
Code:
Bootloader unlock allowed: Yes
then you can enter fastboot mode.
If you see this
Code:
Bootloader unlock allowed: No
then you can not enter fastboot.
Anymore questions?

You have to make sure that your phone has unlocked bootloader, if it says "bootloader unlock allowed: yes" it doesn't mean your phone is unlocked, it only tells you that it can be unlocked.
If you have TrackID, try to play it, if it can be played, then the bootloader is still locked.
For unlocking, try the link below. And don't forget to thank them.

Just DON'T install it. My Xperia Arc s is locked bootloader and i tried to install Ultimate HD Rom twice, but no hope after installation Sony logo stucks!
first time i solved it by using Update Service.
second time (NOW) still on Sony logo and Update Service isn't working, it says "You already have the latest software installed"

Just SOLVED IT! :laugh:
I flashed stock firmware using flash tool
stock firmware link by a member in the forum: http://www.mediafire.com/?rhr59r4o6oarnfx
then::
1. rooted the device
2. installed CWM
3. wiped everything
4. installed UHD and choosing just one app to install
5. unticked reboot
6. wiped Dalvik Cache ONLY
7. reboot device from CWM
8. Enjoyed UHD

UHD is stock based so it will work on locked boot loader, if it doesnt then you're doing something wrongly.

Not necessarily! choosing to install all the apps in the AROMA Installer causes sticking on Sony logo in locked bootloaders.

[Q] Issues unlocking bootloader Sony Xperia Arc S LT18i

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.

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.

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.

[Q] Unlock Fastboot on a Network locked phone which payed method? (r800a) Wotanserver

Hi Xda I'm currently trying to find out which pay methods will enable fastboot on my currently network locked R800a.
I've seen many threads stating that if I want fastboot I'll need to pay and thats fine but I was just wondering if Wotan server is one of the methods that will work for me.
Here are some of those threads stating I can pay but none point to Wotan as a actually one (from what I can see on wotans site they can Unlock the sim network lock and as a biproduct of that unlock it also unlocks the Boot loader but it doesn't state whether it will enable fast boot on an (R800a) or any others. It seems that on any generic XP unlocking the bootloader is all that's required to enable Fastboot.
http://forum.xda-developers.com/showthread.php?t=1330058 , http://forum.xda-developers.com/showthread.php?t=2040779&highlight=enable+fastboot , http://forum.xda-developers.com/showthread.php?t=1330058 , http://forum.xda-developers.com/showthread.php?p=18138850 , http://forum.xda-developers.com/showthread.php?t=1497172&highlight=enable+fastboot , http://forum.xda-developers.com/showthread.php?t=1236892&highlight=enable+fastboot
My R800a is currently stock, network locked, unrooted, Bootloader unlock status allowed: no, and under the 12W11manufacturer date (12w09)
In the end I want my phone Network unlocked, rooted, bootloader unlocked with fastboot enabled so I can install CWM and customs roms/kernels the easy way. as opposed to having to find hard to find custom ftf kernels ( http://forum.xda-developers.com/showthread.php?t=2187172 )
Anyway if you read through all that thank you for your time and unlike some of those others I will actually post back to this thread if I get any solutions that work for me.

I've seen many threads stating that if I want fastboot I'll need to pay and thats fine but I was just wondering if Wotan server is one of the methods that will work for me.
Here are some of those threads stating I can pay but none point to Wotan as a actually one (from what I can see on wotans site they can Unlock the sim network lock and as a biproduct of that unlock it also unlocks the Boot loader but it doesn't state whether it will enable fast boot on an (R800a) or any others. It seems that on any generic XP unlocking the bootloader is all that's required to enable Fastboot.
http://forum.xda-developers.com/showthread.php?t=1330058 , http://forum.xda-developers.com/showthread.php?t=2040779&highlight=enable+fastboot , http://forum.xda-developers.com/showthread.php?t=1330058 , http://forum.xda-developers.com/showthread.php?p=18138850 , http://forum.xda-developers.com/showthread.php?t=1497172&highlight=enable+fastboot , http://forum.xda-developers.com/showthread.php?t=1236892&highlight=enable+fastboot
My R800a is currently stock, network locked, unrooted, Bootloader unlock status allowed: no, and under the 12W11manufacturer date (12w09)
In the end I want my phone Network unlocked, rooted, bootloader unlocked with fastboot enabled so I can install CWM and customs roms/kernels the easy way. as opposed to having to find hard to find custom ftf kernels ( http://forum.xda-developers.com/showthread.php?t=2187172 )
Anyway if you read through all that thank you for your time and unlike some of those others I will actually post back to this thread if I get any solutions that work for me.

Awesome but just to double check you have a Sim locked Telephone company branded phone that was network locked that had it's bootloader status as Bootloader Unlock Status: No and after using Wotan server you were able to go into fastboot mode?
Could you let me know what your phone model is?
if so awesome I hope to do it tonight it's just that Unlock bootloader (can't post website) guy (some Xda member) promises to unlock fastboot
but Wotan doesn't. I emailed wotan yesterday but they're repsonse wasn't particulary helpful (I was asking a lot of other things too so maybe that's why they missed that one.) I'll post their responses here when I get the next one.
Anyway thanks for the response and glad my post helped.

Heres are my messages with wotan server and their responses.
"Hi Wotanserver,
I have an R800a and after digging through countless XDA posts I was unable
to confirm whether Wotan server would work for me.
I have an R800a
Unrooted, Bootloader still locked, and Sim network locked.
Rooting Status:
Bootloader Unlock allowed: No (not to sure if this is super important or
not)
Manufacturer date 12W09 (manufactured before 12W11)
Locked to telstra (australia)
I would like to unlock the bootloader so I can run custom roms. I would
also like to Unlock the Sim network lock so I can use it off telstra. And i
would like to be able to use fastboot mode on my phone so i can install
custom roms through that method.
Is it possible to do all of this after using your "Network Unlocking Sony
Ericsson Xperia PLAY by USB" package?
If not what can I get done?
After this is done will I still need to run the official sony bootload
unlocker or not?
and when I end up purchasing this am I doing this by myself or is there
some one assisting me through vnc server like some other services I've seen?
Can't wait to hear from you

Wotan Server; said:
Hello,
Your phone should be compatible with our service.
The unlocking service unlocks the network and the bootloader.
Official updates are disabled after unlock.
You just need to install and run X_Unlock_Tool_Setup_Wotan.exe
There's a detailed video guide included directly in the unlocking tool.
Kind regards,
Tomas

" Hi Tomas,
but will it enable Fastboot mode on my phone through your method? seems
like it's difficult to unlock fastboot on the (branded phones with unlock
mode allowed: no ) r800a
Hope to hear back from you soon so I can use your tool.

Just used wotanserver and Success!
No longer Network locked
Device can go into Fastboot (blue led when plugging usb and holding Search button)
Device can go into Flash mode Green led (hold Back button plug in usb)
Rooting Status BootLoader Unlock allowed: Yes
Awesome
so glad that worked now to read tons more Xda threads for find good kernel and rom combos for the R800a. Working on the XP is much more complicated then the standard Cm9 install for touchpad! whew...

Arc S 12W22 bootloader

My phone is manufactured in 12W22, is there ANY way to unlock the bootloader? It's a carrier branded phone (got it as a gift)

It is unlockable but you need to remove the carrier branding first.

Any Arc manufactured after 12W11 will have a bootloader that cannot be unlocked. You can try wotanserver for the debranding but not sure if you can unlock your bootloader.

Mine's LT18a 12W15, perfectly unlocked and running JB so.. I'd tell him to give it a shot.

Of course, that number could be just a rumor, no harm trying it.

Hi mine is an Arc is network unlock as its an orange one and I'm using Vodafone. The numbers on it are 11W12 and I filled the thing in on Sony boot loader site and they've sent me a code.
I've rooted it already but it says in the service menu it says the bootloader can't be unlocked.
Mines an LT15i but it now says its Lt18i
What's right can it be unlocked or not?

I understand you came from Samsung... I also used Samsung myself back then and experimented with the root and everything.
Rooted a S3 back then which had the "recovery-from-boot.p" script that did not allow me to flash CWM recovery on it.

Wrong, official method still works for non-SIM locked phones. Branding has no effect at all.

As I already said, it does not matter, if phone has branded firmware or not. It has nothing to do with bootloader unlocking.
If the fastboot is disabled, then you can not do anything. This mostly occurs, when phone is SIM-locked.
If the fastboot is enabled, then you can use official method at unlockbootloader.sonymobile.com.
To see, if fastboot is enabled or disabled, just try entering it - Turn off the phone, hold down Menu button, connect USB cable. If blue LED lights up and stays on, fastboot is enabled and you can use the official method.

I can't enter fastboot, my phone is sim-locked. I think that I could get the unlock code from my carrier, would that make any difference?

Unfortunately, no. This does still not enable fastboot. Fastboot can be enabled only via test point method, but due to newer security systems, this is not possible on phones manufactured after 12W11.
So, unfortunately, you are one of the unlucky ones, who have to deal with locked bootloader. For now. Until a method is found, that can bypass the newer security standards.
