[GUIDE] Unlock lumia x2x and enable Mass Storage mode

[ADeltaX]

Hello,
this is a guide to unlock bootloader!

Prerequisites:
WPInternals: http://www.wpinternals.net/index.php/downloads (Download the latest one, 1.2)
WDRT: http://go.microsoft.com/fwlink/?LinkID=525569 (Needed for drivers)
HEX loaders: Link
FFU Image of your phone (You can download it from WDRT or from the site www.lumiafirmware.com)

SBL3 Engineering: Link
(SBL3 is supported only on: L520-620-625-810-820-822-920-925-1020)

Optional:
OSFMount: http://www.osforensics.com/tools/mount-disk-images.html

Procedure:

1) Download and install Windows Device Recovery Tool (WDRT)
2) Download Windows Phone Internals (WPInternals) and extract that in a folder (for example C:\WPInternals)
3) Create a folder named "Loader" into C:\WPInternals
4) Download HEX loaders and extract it in the folder previously created.
5) Download SBL3 engineering archive (Only if you device is in supported list)
6) Create a folder named "SBL3" into C:\WPInternals and extract the SBL3 Engineering archive.
7) Download FFU image of your phone from WDRT or from lumiafirmware.com

You should get this:

Optional:

Now, connect your Windows device and start WPInternals:

Go to "Unlock bootloader" (on the left) and press ok, your phone will be rebooted into flash mode:

After entering flash mode you should do:
The first one you need to select an FFU image
(If you downloaded it from WDRT, go to C:\ProgramData\Microsoft\Packages\Products\RM-xxx\ and select the ffu image file. WARNING: ProgramData is an hidden folder!)
The second one, select the folder "C:\WPInternals\Loader"
The third one, if you device is supported, select your SBL3 Engineering image (In my case, Lumia 920) from the folder "C:\WPInternals\SBL3".
BEWARE that you can brick you phone if you flash the wrong image.

You should get this:

Now press continue and wait.

DONE! You have successfully unlocked your phone!

If you flashed the SBL3 image, you can access to Mass Storage Mode.

Is there a way to do this on other version of WM 10 than the ones supported by WP Internals?

Should work on all versions of W10M

 

[Satirus]

is it necessary for what?

is it necessary for what?

Editing BCD, creating custom roms, and so on (and someone expert can create custom rom based on android for example!)

Yes, it should work with that version.

Beware! I just tried unlocking the bootloader of 10586.242 on a Lumia 925 (RM-892) and got stuck at "Sending Loader". Next I'll go the recommended way:

• Flash a Windows Phone 8.1 FFU
• Run Windows Update until you have at least version 8.10.14219.341 of the OS
• Unlock the bootloader using an Engineering SBL3 (only possible on compatible phones)
• Run the Windows Insider tool and update to Windows 10 Mobile, possibly needs to run Windows Update a couple of times for the latest build
• Enable Root Access directly on the phone
• Bonus: Create a Cusom ROM

// update:
After several failed attempts (*aaaahahhhrhhrrgggg!!!!111111eleven*) I finaly got it:
Drivers from the Nokia Care Suite and the correct(tm) loader ftw.

Go on "Enable Root Access", an click on Unlock Phone. It should work.
PS: You need an engineering SBL3.
