NOTE : IF YOU HAVE A LUMIA 800 WITH QUALCOMM , PM ME


Second : IF YOU HAVE NO IDEA WHAT YOU READ PLEASE DO NOT TRY THIS!
GET IN TOUCH WITH ME OR A MOD, WE WILL HELP YOU.
I CAN TRY TO HELP YOU REMOTELY BUT WE'LL NEED TO ADJUST THE TIME.

Third : There is some risk in this if you dont do it correct by yourself, myself and no one is responsible for your device.
This is all under your own risk.
Even if we help you i tell you till now i havent nor any of my friends havent bricked a phone.
To make sure, we are well aware of how this works.



You need Something called as a Qualcomm on 800 and 710

For a 710 device , any 710 can be unlocked, even if it has a DLOAD.
For an 800, only a device showing up as Qualcomm can be unlocked.
A DLOAD in 800 cannot be unlocked as yet.

To know what type of Loader you have follow this :

Open device manager in you PC (Just so you dont miss the driver installation, its better view able in Device manager)

Power off your phone , dont plug the USB as yet.

Hold VOLUME UP button and plug the USB in the PC.

Check device manager.

You will have a DLOAD or a Nokia cable connectivity or a Qualcomm technology.

In case of DLOAD and Nokia cable connectivity. Nothing else will be noticeable.

If you get a Qualcomm, u will get a box to format Disk, say NO!



SO now

Qualcomm = unlocked bootloader

DLOAD = Locked bootloader



* UNLOCKED BOOTLOADER = NO NCS = YES CUSTOM ROM
* LOCKED BOOTLOADER = YES NCS = NO CUSTOM ROM



For Lumia 710 users, u need to flash a Qualcomm bootloader (Unlocked bootloader) to enable Qualcomm , so u can Full Unlock your device.

If You have DLOAD, follow the full tuto.
IF you have a Qualcomm, goto step B.

[glow=red,2,300]Important : Flashing a CUSTOM ROM, to full unlock your phone will need a HARD RESET , in which you will loose all your data.
I would recommend you back up all your data, mostly just sync your pics and stuff of you PC and sync your contacts to your LIVE ID.[/glow]
