For any Sony Xperia Device
Totally unlock your Xperia to be able to aply Mods/Roms without any limits.
​Well first of all i want to say that this tutorial was not made by me, im just translating it to the english language so that we can all now about this great tutorial.
Before i begin i wanted to tell you that this great advance in the freedom of Sony Xperia devices has been the result of all the complaints sended to Sony from HTCMania, the following complaints can be seen in the followings links, so if you want to see them just click them:
Claim appeal from HTCMania: http://www.htcmania.com/showthread.php?t=393945
Claim imposed in Movistar Comunity: http://comunidad.movistar.es/t5/Contrataci%C3%B3n-Precios-y/Desbloquear-Bootloader-Sony-Xperia-S/td-p/623003/highlight/false/page/1
This has been an amazing achievement worldwide because this has open the doors to all our Xperia devices from any phone company of the world. With just having a free terminal and with that having the code to unlock the SIMLock, any Xperia S, Xperia U, Xperia P, etc will be able to release the Fastboot and thereby open the Bootloader. This opens the door for everyone to be Root, being able to flash custom Roms. This will encourage people to buy these devices.
Important previous explanations:
It is necesary that you read and understand what is all this about and why they made this claim to Sony.
Sony has two limitations in their branded devices:
1) Simlock Block: this is what dont allow us to insert another brand SIM card.
2) Fastboot block: this is what dont allow us to install custom Roms/kernels
To know the status of those two blocks we can acces a secret menu of Sony. We have to dial this: *#*#7378423#*#* and we will see this menu:
Entering in Service info > SIM Lock we will see if we have the Simlock or not.
Entering in Cofiguration we will see if our Fastboot is blocked.
When we buy an unlocked device, the secret menu will show this:
SIMLOCK = NO
Unlock Bootloader ALLOW = Yes
When we buy a branded device, the secret menu will show this:
SIMLOCK = YES
Unlock Bootloader ALLOW = NO
If in the operator we do not have permanency, the have to give us the total unlock code. That will let us use any brand Sim card in our device, but we stil cant Root it like an unlocked device, for that we have to open the Bootloader. For doing that we have a code similar to the one to unlock the SimLock to make the "Unlock Bootloader ALLOW: no" to "Unlock Bootloader Allow: yes". Doing that we will have our device in the same conditions that an unlocked device. Then its the user choise to open the bootloader or not.
Well the problem was that Sony didnt know if we really had the right to totally unlock our device, they have reached an agreement. When you have the code to unlock the SimLock you have to get in touch with Sony support service indicating your E-mail, IMEI and the Simlock unlock code that indicates (if the code is correct) that the device can have a total unlock and therefore they will answer our mail to confirm a date of collection of the device so that Sony from their SAT unlock our device and then return it to us unlocked.
Doing this the deviche will be like an ulocked device.
After that, depending on device (Xperia U, Xperia P, Xperia Sola, etc) you have to follow the procedure indicated by sony to open Bootloader.
Steps:
1) Unlock the Simlock of the device
If you dont have permanency with the operator you have to call them and ask the code for free. Depending on the operator this can take from 5 to 15 days
2) Once we unlock the SimLock and we have the unlock code we have to send a mail like this to Sony:
To: Sony mobile Support E-mail (it changes depending on your country)
Subject: Request for unlock FastBoto of -your device here- - IMEI: XXXXXXXXXXXXXXXXXXX
Good morning/evenening/afternoon
I own a Xperia device wich have no permanency with any operator and i posses the unlock code of the Simlock that my operator gave to me.
Because of that i request the fastboot unlock, that would change the "Rooting Status: Bootloader Unlock Allowed: NO" to "Rooting Status: Bootloader Unlock Allowed: YES" to have the same privileges than an unlocked device and later if i wish to, aplly in your web the opening of Bootloader.
To making that possible i supply you my device information:
IMEI: XXXXXXXXXXXX (you can get this by dialing *#06*)
SimUnlock Code: XXXXXXXXXXXXXXXXXXXX (the one we asked to the operator)
Model/Device: -Your device here-
Mail: -Your mail here-
Phone: -Your phone number here-
With no other particular, accept my best regards and I hope your answer.
Thank you.
-Your name here-

3)Sony can answer us different things:
*They can tell us that the SimUnlock code is not correct. In that case you have to call your operator again and ask them to send you the code via mail and then you resend the mail to Sony. That will confirm that your opearator ease you the code legally. If Sony deny to accept you will have to justify your request with a bill that demostrate that you have no permanency with the operator.
*They can tell us that the request is ongoing, here you just have to wait until the confirm if they accepy or deny your request.
*They can tell us a pick up date of the device to unlock it. This is the good one. We have to call them or answer the mail to come to an agreement. They give us a time limit of 15 days to return the device to us. Then we just have to wait them to return our phones. All this is free.
And we are done, with this we have our device unlocked and you can flash custom roms, kernels, root your phone or whatever yo want to do. The only thing to do now is enjoy our unlocked device.
To verify that the device is unlocked you have to enter the secret menu again. If iy is unlocked it should show this:
Thats all friends, i hope this helps you. And again this tutorial is not mine, i just translated it for you.

Yea, you have to send them your phone but its not that much time, it ussualy gets them 1 week to unlock your phone. They say 15 days so the dont have any problems if they get a little retrased.

Yeah thaths the bad part, some people have to wait until their contract ends. But eventually you will be able to unlock your fastboot.

Are you sure it will work in any country? I heard it's only because phone companies in spain had a special deal with sony. I can't do it right now because i wont be in my home country right now for some time and they will only unlock local phones. Ex: My phone is portuguese and spanish sony said i need to do it in portugal

I am nobody to give you any kind of redemption for what you have done, but if you do regret it, don't do it again.
Warranty is supposed to protect consumers from defects, not helping them get new hardware for free.
