STEPS TO UNLOCK BOOTLOADER
1) Get the IMEI code for ur device: type *#06# in phone dialer to find it out, note only the digits (no dashes)
2) download the fastboot package with usb drivers(GOOGLE IT)
3) Now Get the UNLOCK KEY FROM SONY from HERE
4 ) After u have verified that u can unlock bootloader, scroll to the bottom of the page and click "Continue"
you will get numerous prompts, read all info and if u agree click on "Accept"/"OK"/"Proceed"
finally u 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
5) Extract fastboot_with_Android_USB_file.rar and open fastboot folder
6) Hold SHIFT and right click on the background of the folder Select 'Open command window here'
7) 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)
8) 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
9) Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which u received earlier.

good job bro!
I just wanted to ask if we could unock the bootloader using flashtool so there's no chance of voiding warranty. As backing up TA would save DRM keys.

Yes u can unlock it using flashtool. I am windows 8 so i find unlocking with fastboot is easier and it just just cause 6 mb of data.

I see.
Well I tried with flashtool it denied unlocking :silly:
I think it would be better to go with the official unlocking.
Thanks.

u should add the TA Backup guide also

You need to restore the stock boot partition because restoring TA partition will relock the device or else you will soft-brick it. If you have a dump of it you can restore it before restoring TA partition, otherwise you need to reflash with flashtool or SUS.
This is what I learnt from other Xperia devices in general.

Can you still use SEUS when you have unlocked the bootloader to restore the original firmware prior to re-locking bootloader?
I thought it would be via flashtool only, because as soon as you unlock the bootloader you lose access to PC companion and SEUS.
The reason I ask is I have an XPERIA X10i and you can use anything at any time and it doesn't care.(brilliant olde device)
With my XPERIA S, I only have flashtool, as SEUS and PC Companion (and Sony OTA upgrade) are 'lost' after the bootloader is unlocked.

Really? PC Companion can recognize my Xperia M. Haven't tried SUS restore but it should work, shouldn't it? FOTA updates are known to brick unlocked Xperia devices so I strongly advice you not to try it.
But anyway if you've already restored the TA partition you already have a locked bootloader

PC companion still can recognize your phone even you've unlocked your bootloader, but updating your phone with SUS / PCC will surely brick your phone.
The only way to restore to the original firmware is using Flashtool or EMMA :fingers-crossed:

I dont think Pc companion will brick your phone! I never heard of this things and yes updating through FOTA can definitely brick your phone. Although i recommend not to unlock bootloader unless you are an advance user or a developer.
Sony xperia M gives very good performance over stock so noo need of scripts and other stuff, and i hope someone will develop CWM for locked bootloader too.

Here are device files for Flashtool with loader.sin file for success bootloader unlock/relock through Flashtool
C190X C200X
1. Unpack it to '/Flashtool/devices/' folder
2. Run Flashtool and select in 'Devices/Manage/Import' M or/and M Dual
3. Now your can use BLU button

I have NOT backed up my DRM keys.. and I have an unlocked bootloader...
I connected my XM SS to Sony PCC..
It did recognize my phone.. However it did not update it stating that I am using a modified software..
Flashtool (EMMA) also recognized my phone.. but dint allow me to update my phone..
And my phone is not BRICKED..
Can you be more descriptive on the exact instructions on how you can relock XM whose DRM keys are not backed up?
Has anyone tried this?
Please quote and reply and share the method if you have tried this on a C1904 XM SS and if it is working !!!!
Thanks

I have a question...
How will I be able to backup my TA partition if root is required? I have not yet rooted my phone. I only rely on official procedures because I have bricked my two other phones previously. Have you had root installed on your phone when backing up TA partition?

[Q] Xperia play Gingerbread to Jellybean/Kitkat

Hi can anyone advise what the problem could be?
I have been trying to upgrade my Xperia play from Gingerbread to Jellybean and failed,
My handset is Bootloader unlock Status = No, although O2 unlocked the carrier so I could use any carrier.
So when I goto Sony bootloader unlock site the phone will not goto fastboot mode. Just says Waiting
When I open Fashtool I have successfully rooted the phone, but when I try to Flash the phone rather than go into Fastboot mode the just restarts.
I am using Windows 7 64bit.
Any help on getting this done is greatly appreciated

Umm I think only the simlock has been removed. But the bootloader is still locked and cannot be unlocked. and what button are you pressing to go into flashboot?

I have used search button whilst plugining in USB.
Does that mean bootloader is locked, so impossible to unlock?
The sticker on the back of the phone is W46. Read somewhere that using Flashtool may damage the phone.
Thanks in advance

SIM Unlocking the phone inst the same as Unlocking the Bootloader. If you Have Bootloader unlock Status = No you can still unlock your Bootloader via the Test Point method.
If you Unlock your phone with the Test Point method you will not have acces to Fastboot Mode, but you can still Flash Kernels via Flash Mode Using the FTF version of it(insted of a boot.img file).
Look in my signature if you want any FTF kernel.

Just read the instructions for whatever kernel you are using, and same with the rom you want to install.

Sent from my R800i using XDA Free mobile app

As above, follow the guide above. Since you unlocked via the testpoint and there's no fastboot, you need to have your kernels in a .ftf file format.
Here's a thread with download links to ftf kernels: http://forum.xda-developers.com/showthread.php?t=2739559
You will need to use flashtool to flash them. The JB ROM can then be flashed via recovery normally.
My Xperia PLAY was locked to O2 as well and testpoint unlocked, and these have been working fine for me so far... although for some reason my phone stopped working with ICS ROMs. GB and JB still works however.

Phone bricked.
I flashed the Lupus JB kernal and then entered recovery menu and deleted formatted and now it just a blank screen as if the phone is off yet plugging in the usb is recognised by computer yet flashtools and Sony companion can't repair or recognise.
Any ideas?
Grover

Exactly what did you delete/format under recovery? All I did was pick the factory reset option, then wiped cache and dalvik cache, and then flashed the ROM and worked fine for me. I'm using version 8 of the kernel however for the extra data space.
Here are the ftf files for the stock original Sony firmware, which you can use to restore your device if flashing goes wrong (.79 is the latest): http://forum.xda-developers.com/showpost.php?p=43935357&postcount=2

I formatted the file as you did and it came on with a blank lit screen so I flash the default file in firmware a on flash tools to get nothing but a blank dead screen
Any help is greatly appreciated
Grover

1) Download the .79 ftf firmware and place it in Flashtool's firmware folder.
2) Open up flashtool, and plug in the Xperia PLAY in flash mode (hold back button while plugging in USB). Flashtool should report the device is in flash mode.
3) Press the flash button (lightning symbol) and select the stock .79 firmware, then confirm to flash that.
4) Wait for it to finish flashing. Flashtool will then ask you to reboot the device.
5) Unplug the phone and hold the power button until it vibrates. Let go and it should boot back into the stock Xperia software.
It should now be back to stock, and you can attempt to try custom ROMs and kernels again.

Unfortunately this is where the problem lies. Flash tools doesn't recognise that the phone is there hence can't flash it with stock firmware.
It is In a dead state. Is there anyone who offers a service to Unbrick it and what tools are required?
I am not dettered by having bricked my phone, as this is all part of my learning, although I would appreciated a possible fix to Unbrick it.
Thanks in advance
Grover

Have you installed the drivers for the phone from the flashtool driver folder? Have a check here on how to do it: http://forum.xda-developers.com/showthread.php?t=2054486

All the drivers where installed as per instruction. The phone is in a state of being off all the time no lights or anything.
The only thing that is heard is the usb sound on the computer when it is connected.
Flashtools Sony Companion doesn't see the phone at all.

But my bootloader was unlocked Via testpoint and i have both fastboot mode and flash mode working fine, i install kernels via .img like everyone else and im a r800X cdma user.

Yes, if you unlocked your Bootloader via the test point method for the R800x and the R800i you should have access to Fast Boot Mode. You only don't get access to Fast Boot Mode if you have "Bootloader unlock status: No"(and unlocked via the Test Point Method), witch is about 100% of R800a users.

As above. Sadly, all phones sold from O2 UK have bootloader unlock as no, so the normal way of unlocking won't work and only the tespoint method is avaliable... So no fastboot. Due to that, I buy my phones unlocked and unbranded now. Luckily thanks to the great developers on here we can still root and play around with custom ROMs.
What version of Windows are you using Grover? I'm not sure if it's related but I have problems with adb/fastboot drivers on Windows 8/8.1 with HTC devices. Everything works perfectly on 7 though.

ta backup has nothing to do with relocking bootloader
it is used to save some features of sony
relocking has not been made yet
and why would u want to relock?

To use SUS, you must have a locked bootloader. For those who have an unlocked bootloader, just wait until someone uploads an FTF. FTFs can be flashed on unlocked bootloaders using Flashtool by Androxyde.

You can easily relock the bootloader in just two steps.
Flash only the kernel via flashtool and then relock the bootloader also via flashtool.
You can't go wrong if you've used flashtool before.

The process is quite simple but do it at your own risk..
Turn on your computer's internet..
Open flashtool and select flashmode..
Select the firmware, then exclude everything but kernel (Remember only kernel should be selected, exclude everything)..
Uncheck every option in wipe..
Flash the mobile, it should take just 4-5 seconds..
Don't restart yet, disconnect your mobile..
Open BLU option in flashtool..
Connect your mobile, a dialog box will open, just click on relock..
(Remember, don't turn off the internet connection untill the bootloader is locked)
Restart your phone, it'll still be rooted and you'll be able to get all official updates..
Only thing you'll lose is the cwm recovery..

You in locked or unlocked bootloader ? If you still locked you can try to flash with PC companion. But if you in unlocked bootloader you must know are your .ftf file that have you downloaded before isn't corrupt . I suggest to redownload that file and re flash again with flashtool using flashmode bro. But if you're .ftf file isn't corrupt just keep connection USB must stable for this flash bro, because if isn't Stable that can't make broke this flash from flashtool I guest so. Try it first ya:thumbup:
