Hello,
I have Xperia D6503 with 6.0.1 rom,but it's locked bootloader by default,so I need someone who can unlock bootloader.

D6503_23.5.A.0.570_1281-1977_Customized-MY.ftf
this is the firmware,but it;s locked bootloader and I need someone who can unlock the bootloader.
I tried already with with serial number from sony but in fastboot it says "command denied"

Does it say bootloader unlock allowed in the service menu ?
Did you try using flashtool ?

yes,in service meny says bootloader unlock: NO
I tried with fastboot,but without luck

yes I've have unlocked bootloader actually that sim issue started just after unlocking the bootloader , baseband is .71 I'm on stock right nw & yes my sim is unlocked I'm beginning to think that issue is a hardware thing :S
did you resolve problem witch the signal ??
no i didnt :S
Did you flash the A1 kernel before installing this rom.
You unlocked your bootloader with the wrong tool or you unlocked your X10 from another unlocking service than setool , next time read all info before unlocking your bootloader
You can unlock your X10 with setool then you will have the right certificates and it will work
or
you can relock it with the tool the_laser posted in this thread but ofc you won't be able to flash some ROM's
I resolve this problem

I wonder many ppl are facing this same problem after unlocking their bootloader. I reverted to 2.1 fw, unlocked it and restored 2.3 and flashed .71 baseband. Its working fine.

[CLOSED][Q] How to Relock Bootloader (Xperia Mini Pro)

How do I relock my Xperia Mini Pro? I unlocked it through the official way on the Sony Website and wanting to relock it now. I reflashed my phone to stock ROM with stock KERNEL and want to lock the bootloader. I downloaded Flashtool and now I don't know what to do. Should I use Flashtool or S1tool? Please help, thanks
Plus, Flashtool is not recognizing any drivers I have installed, I installed my phone's driver using Gordan Gate's which I got from WontanServer. Will I have to install the drivers manually?
If you used official method, you will need this file, attached to my post, inside the .rar file, and Flashtool. Just place the .ftf file in Flashtool/firmwares folder, then open Flashtool, flashmode and pick the relock_bootloader.ftf file. Make sure your phone is in Flashmode also.
About drivers...I cannot remember, which drivers did I install...
Thanks, a lot, I have finally relocked the bootloader. But just to make sure, how can I check If my bootloader is locked or unlocked? Thanks

Dial *#*#7378423#*#* service info>cofiguration.If it says bootloader unlocked allowed : yes then it's locked, if bootloader unlocked : yes then it's unlocked.
One qeustion by my side: After relocking the bootloader, is it posiible when you send it to the servis to be detected that the bootloader has been unlocked (or maybe that the device has been rooted) previously? I have relocked the bootloader and done repair with Pc companion so everything is like before well.....except that before i did a root with flashtool and didn't knew that the stock firmware isn't rootable like that and i lost 3G!!!!!!...now i must set to 2g in order to get signal coz i get with 3g weak signal and when i make a call it drops off. That's why i want to send it to the service

Read the topic title.
Did you flash the .ftf file with Flashtool properly? It worked on me perfectly, was able to lock the bootloader without problems.

No i didn't try to relock it and i'm sorry for the misunderstanding..
What i was trying to say is that if i reflash my phone to stock ROM with stock KERNEL and take it to service how will they know that it's unlocked?
If they try the known dial *#*#7378423#*#* method my devise says : bootloader unlocked allowed : yes

I knew that your post had nothing to do with relocking patrida If you unlocked your phone with sony's official method you loose your DRM even if you relock it.Now, about the service, i highly doubt they gonna search if you unlocked it but i can't swear about that.There is also another method unlocking your phone without loosing DRM but didn't tried it and i don't know if they can detect it or not
T3sla said:
... you loose your DRM even if you relock it...

Now i get it.. you loose your DRM the exact time you ask them to provide you unlock code!
So,no matter what you do afterwards they allready know which device is unlocked and which is not.. sosta thessalonikie mou??
My phone is unlocked with the "other" method and let's hope that i'll never have to take it to them and wonder if they detect it or not!!!
My phone now is locked and to check if your bootloader is locked or not, download S1tool. Open S1tool and click "Identify" and then follow the onscreen instructions. When your phone's information comes up it will say "R(some numbers and letters)". If you have a capital R means your bootloader is locked, if you have a small r means your bootloader is unlocked.

You lose DRM, if you unlock via fastboot using official method. When DRM is gone, it is completely gone, currently there is no way of getting it back.

Will try that tonight and get back to you with the results!
Can you guys please tell me what this "other" method is? The one by which you can unlock a Xperia Mini without loosing DRM.

[Q] need help to unlock bootloader plzzz

hi i am a new user of xperia neo.....in my device bootloader unlock allowed says NO...now can anyone help me to unlock my bootloader ???? plzz someone help me ,which method i can use to unlock bootloader....and if my bootloader is lock can i use recovery mode on my device ????
Please read the stickies before posting.
Boot loader unlock no= no fast boot so you cannot flash custom kernels, but you can flash all stock ones including ics.
You can still root and install cwm, this will allow you to flash any rom for locked boot loader.

and bro my android version is 2.3.4 & build number is 4.0.2.A.0.42...how can i downgrade my android version to 2.3.3 ????
Actually no you can just read the stickies, you are going to murder your phone, you cannot downgrade to 2.3.3 you'll get the 0% battery issue.
Why people start messing with things without research I don't know.
Do your self a favor and read the stickies before you try anything else you will find the right way to root

I would also want to know if this is possible. Got a locked xperia P and I tried following the guides here and checked the CM website, but it's very bad organized. Two years ago when I was into rooting and modding it was all organized and easy to follow.

It work with locked bootloader?
As you can see below, to install this rom you need to flash a new kernel, which isn't possible to do with a locked bootloader.
So the answer is no, unfortunately you can't.
