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 http://forums.windowscentral.com/nokia-lumia-920/341531-windows-10-preview-nokia-lumia-920-a.html
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 ?

 

Installing Windows 10 on Lumia 920

Got a Lumia 822 with Windows 8.10.14203.306 (plus, also, ran WP 10 for a short while... to many problems in the earlier versions; so, I put 8.1 back).
And, Glance is not needed as an app add-on (as it was on WP 8.0 and WP8.1)... it is included in the settings and works great in WP8.1 update and WP10.

If you are in a country that WP10 is available at this time and your phone is listed, all you need do is sign up for the Windows 10 insider app on your phone and run update to install the WP10 preview... no hacking needed.
Or, you change your phone to US, as you did.
You don't have to do all the hacking this and that.


EDIT:
If you do not have Glance on your phone... you can try searching the app store for it and install or re-install it; or, try the app Nokia update and see if that will install any missing items.
There is a Glance screen bug, where some people are not getting the glance screen.
There are some other bugs where people have had to reset phone or re-install the everything.

Goodluck.

 

Installing Windows 10 on Lumia 920

These are the official EASy steps on how to do it. http://www.windowscentral.com/how-install-windows-10-preview-windows-phone

There very simple and i've already tried them. The problem that i face is that the software (this app) does not find any updates for me .
Many people across the world have this issues .So you need the proxy etc thing to get it to work.
