Mainline for OPI One / Dev version question

Hello,

Recently I bought my first orange pi one and I downloaded the xenial desktop specifically so that I could have an xserver preinstalled to what I wanted to transform into an access point.

I had realized that all realtek wifi dongles would cause a kernel crash once you try to connect to an access point with them. I had followed instructions to rebuild the orange pi with the dev packages that are found on its download page, and it worked the first time, allowing me to continue with my work. Long story short I ended up re-imaging the sd card and now I can't get the dev version to work again. It won't boot once I install the packages.

I am wondering if something has changed or that is just a problem for me.

Also I attempted to get the mainline packages however there is no mainline u-boot package for the OrangePi One like it says here https://www.armbian.com/kernel/.
 

It would be appreciated if I could know how to install the mainline packages if there are any / a way to get the dev packages to work again. OR if neither of those is an option It would be helpful if I could get some more help with using the legacy build with the realtek dongles I have.
