Installing Windows 10 on Lumia 920

I have a Lumia 920 mobile phone.
Found a list on the net with compatible phones that support Win 10. Mine is on that list.
Can't upgrade with the usual way.
Found help on this official website of developers for Windows Phones. It's a step by step no brainer thing. Most people are doing it. Except me. I can't get past point 6. HOWTO: Install Windows 10 for Phones on Non-supported devices (and other hacks)

"6.Connect to the same WiFi that your PC is on. Edit the settings for the WiFi connection to turn on the Proxy and set it to use the PC’s IP address and enter 8877 for the port "

7. Open Internet Explorer on your phone and navigate to http://[pc.ip.add.ress]:8877 where [pc.ip.add.ress] is the IP address of the PC running the WPInsidersHacks app
No idea what this means.I guess i need to access the router and modify some settings in there. Some guy on the forum told me " think he means to use the local IP address of the pc. Go to cmd and type ipconfig and look for ipv4 address. Should be somethin like 192/......"

I did connect my phone as always via wi-fi to my router. But i have no ideea how to use that proxy or how to make my phone have the same Ip as computer. I did start WPInsiderHacks app on pc. This is what it looks like




Theres also this official Windows Phones
It says this :
1. Download the Windows Insider app.
Press ... > about > make sure Sys free space is 300MB or more.
If there isn't enough space, make full reset with Windows Phone Recovery Tool.

Code:
upwp10.chinacloudapp.cn:7777

Download and install certificate.
3. Edit WiFi connection, enable Proxy

Code:
upwp10.chinacloudapp.cn
7777

4. Open Insider app, click get builds
5. You will get Enroll page, do not Enroll yet!
6. Switch to WIFI settings, turn off proxy.
7. Switch to Windows Insider app and now you can enroll for Windows 10 Technical Preview.
Choose Fast option.
8. Check Settings > Phone update.
If it can't find updates, you may need to reboot your phone and enroll again (without a proxy now).

Same thing with the proxy. Anyways the more detailed steps on the DEV forum are much better i think .Cuz they put out more info on how to do it.

Can anybody help me with step 6 ?
