Anyone Know How To...Reset Software Update Info So Marshmallow Will Download?

[Blessedx4]

Anyone here know which setting has to be cleared/reset in order to prompt the phone to download the Marshmallow update? I had it until yesterday when my phone store told me to hard reset my phone and now I am stuck back in Lollipop with the phone saying it is up to date.

I had found a way months ago, but can't find the page again. It was in the App Manager and you had to reset or clear cache or stop something running to make the phone go back out and look for an update.

Thanks!

Z3V...I bought it, supposedly brand new, in August.

Ok, neither XC nor Flashtool/xperifirm will work, you can thank big Red for that, Verizon, the only thing you can do is to take it to them and for them, Verizon, to fix it.

All i can recommend is to Try settings>apps>all and scroll down to update ones,open and click force stop and clear data and cache

Then check for updates again,
