Can't install Windows 10 mobile on my lumia 920(with insider)

Hi, i using lumia 920(windows phone 8.1 denim), I install "windows insider" and selecting insider slow or fast, restarting and when i select check for updates, writing "your phone is up to date" , i make hard format and flash with windows device recovery tool and never changed. Try everything but say "your phone up to date". Please help me.

I understand that. I did read the previous posts and have done that. After I select the release ring it says the update is ready and to go to my phone update menu. When I go there and select Check for Updates it says "We are currently unable to check for updates (80072f8f)". It has been saying that ever since I installed the first thing that installed when I started Windows Insider.

is your time, timezone, date and region correct? Check properly. To be on the safe side, set it to manual

Everything is correct and I set it to manual.

if you're really determined to have windows 10 mobile, then you'll have to do a factory reset and start again on the upgrade process

That was one thing I was hoping to avoid.
