Things to check:
1. Is the phone connected?(Plug to the USB)
2. Is it in the correct mode?(Try to switch to OSBL mode)
3. Have you installed the Qcom loader ?(Use the Install button)

Hi,

When the phone restarts after the change to OSBL mode command, does it stay with dark screen,
or just enters the long boot process and comes in Normal Mode ?

If the latter, you maybe have baseband/ROM mismatch, where some commands are not recognized -
e.g. the restart. Battery level is also not read correct. The solution is to restore to Nokia loader (only on 710)
and flash some version to make sure ROM and baseband files are matched, then install QCOM and do
the sim unlock procedure.

Will this work for any carrier or only for the common ones? I have T-Mobile UK and they have this new lock with Orange UK...

Here the new NSS version (0.50) that allows sim unlock if your Lumia is rooted (710,800). How to unlock:

1. Make sure all drivers are installed, phone is visible by NSS in Normal, OSBL and NAND mode
2. Make sure you have Qcom loader
3. Plug the phone via USB cable
4. Start NSS, go to Simlocks, WP7, press Unlock
5. Follow on screen instructions

Unlock works for PIN and PUK blocked phones.

hey man you are a genius! i have been digging up and trying to find a sim unlock solution since i bought this phone and to no avail. i happened to buy an unlock code for my lumia 710 so i am unable to test your solution to see if it works. i wish you had revealed this method earlier so i would have donated the money to you instead! i am waiting to see if people were successful with your method. for my knowledge though...does it have anything to do with sdb5 partition? thanks again and good luck!

For lumia800?

Hi, in another post you pointed out that your phone was DLOAD and you flashed a generic firmware to your phone which gave you Qualcomm in NSS, could you please give more information on this, which firmware etc. so hopefully it'll work for us too.

/edit - Weird this. If I restart my phone with Vol up then insert USB (till buzz) and then click Detect on NSS it jumps straight to OSBL Mode - WP7 Qualcomm, I can't do anything with it at this stage so maybe (hopefully) someone will have an idea?

That's exactly what I did, and when I pressed 'Detect' my sim unlocked. Try putting a different sim in . But, I want to know what bootloader have due to the confusion of NSS detecting my phone as 'WP7 Qualcomm'.

Just detect on it's own shouldn't unlock it, you'd need to press the unlock button wouldn't you? In settings/About it should say bootloader version, mine is 7.35.0.0. I currently have a vodaphone sim in my phone (locked to Orange) and it doesn't unlock so it's trying to get to the bottom of how yours managed to unlock as qualcomm. Which drivers do you have installed for instance?

Hi,

If you have a phone, check what the Simlock saves as backup. Also after unlock you can try the Restore button and see what is loaded.
