Unlocking my LG G7

[KH1]

Hi everyone
I bought a LG G7 ThinQ handset from Brent Cross O2 shop. Now I tried to unlock my handset for already 5 times and they give me same reason that handset is not from O2. But I had proof of purchase from O2. So I went to Brent Cross O2 and I spoke about this to one of advisor. He called to the customer service and that advisor help me a lot. But my phone is still locked and I can't use my sim card from Vodafone. Does anyone know how to solve this problem?
Thanks

@Cleoriff I already try at Independent shop and they can't do it as well. This evening I spoke with manager from Brent Cross O2 and he said they are planning to give me back my money because it's happened for almost one month.

OK @KH1 Sorry to hear it can't be unlocked, though pleased you will be getting a refund..

Most strange and a refund is probably your best option under the circumstances.

Apologies for the necro post, but I have a work around for this.

O2 refuse to accept that the LG G7 Thinq was ever sold by their network...despite it being lsited on my bill and having the receipts. I believe the issue is actually that the G7 was sold through Carphone Warehouse at the time, since O2 have stopped working with them now this is the only thing I can think of - how a network could "forget" a handset is beyond me.

I have spoken to customer services, sent through sim unlock requests via the website and via the My02 app - both recieve the response "this is not an O2 handset".

I have now successfully unlocked the phone via a sim unlock site, sim-unlock.net. Costs about £5 and took 10mins - highly annoying that I had to pay an extra fiver for O2's incompetence, but a reasonable fee from the supplier:

From the dialling screen: dial 2945#*710#

A menu will open, select the top option 'service provider lock'

Enter the "NCK" code (you will be given 4 different codes for different purposes, make sure you enter the NCK one)

The phone will switch off, turn back on and now fully unlocked

I tried the above on my G7.. but can't put in the code as it gives me only one choice... Your phone is not personalised [dismiss]
