Good morning, Guys!
I discovered this nice thread a couple of weeks ago, and now I wanna report to you Guys that there is still an way to use Origin over EA App. I read the last 3 sites through this thread and I didn´t found an working solution once the method with the xml File also was patched bei EA.
I still don´t want to use EA APP, although it´s working better than previous versions, so I searched recently again for an method. This nice little app here hosted on Github still do the trick. It´s an version.dll File. Once you place it in your Origin Install folder it works out of the box. No more pop ups "please use EA APP" and so on. You can install your games, you can update your games and repair your games. I use the solution since 3 weeks without any sign of EA interacting.
It´s important to say: I don´t know the creator, the file may alarm your Anti Vir Software, saying "dangerous", are you sure you wanna install it etc. For me, it didn´t warn my anti vir or even WIndows defender. Maybe while I am using IOBIT Advanced System care Anti vir. Whatever. I can only ask the Moderators like
@Tom if it´s ok for the Forum stuff to post this here.
The whole quick and easy Install Progress is documented on the github Page. It needs an older version of Origin to be installed. Than place the version.dll inside your Install Folder of Origin. That´s it. Below I show you a Screenshot how it looks in my Own Install FOlder.
If the Moderators wanna delete me this Post or clean them by thereselfes than I understand that of course. Personally I don´t think the creator wanna spy out your PC or similar things. I waited now 3 weeks before I post this here in the thread because of monitoring my own PC if something fancy comes to my attention. But till today I can personally say the file is trusted. DOn´t install it if you have any doubts, Guys!
Oh and yeah, the App title is not so for work. Sorry about that, it´s out of my range.

As you can see in the right bottom corner, Date is from today where I opend Origin.
I am waiting for Moderators
@Tom decision.
