Yeah, that is the infamous "Dwillian Dump", a most excellent method of installing a rom to upgrade, downgrade, or reinstall without losing your updates and settings. Just like Casper said, wipe dalvik, cache, and system, ONLY. Then flash your rom and are done with it. You can also at this time install a new gapps package, but unless you have not been keeping your apps up to date, the gapps that are already installed should be and work just fine. Or, at least for me, it always has. :good:

Welder is very good about taking on the new frontier of Lollipop so if anyone would know, it would be him. I also use Facebook Lite, not from the playstore as well. The Facebook app is a total system hog and a pig. It will take all the resources it can get and never release them. You would be FAR better off if you install Facebook Lite and Messenger if you need to send and receive Facebook messages. First fix your build.prop as per Welder's instructions then search for FB Lite in google like this:

download facebook lite for android

And do not take the link from playstore or Facebook! This one looks good:

Facebook Lite 1.11.1.92.209 (24) APK Latest Version Download

Hm, I am actually using version1.4.0.6-14 because since I did not download from playstore, I do not get updates for it. However, this lite app does exactly what I want so I am good with it. Since I have my FB Lite backed up with Titanium Backup, I guess I will now download the new version, install it, and see if it is good.

Oh, I recently updated a bunch of stuff at playstore so before I do this FB lite update, I am running TiBu to backup everything that is not so far backed up yet, including data. So this might take a while. But I would hate to be the one to recommend something and have it blow up in my face, so I will stick it out and report here. (This NEON theme that Casper told me about is something for sure I want backed up. This is just too freaking cool not to have!)

When you "sideload" an app like this and do not install it from the playstore, you will get a question on the screen asking if it is okay for Google to check this app and monitor it for you. I did not see the question and it was behind other things and I was wondering how long is this install going to take for Chrissakes?! Once I found the hidden question and answered it, NO, the install finished.

Okay so I just checked the new version of Facebook Lite for you and it is a for sure go ahead. As long as the instructions that [MENTION=5057697]welder73[/MENTION] gave you are correct (I have no reason to doubt him, Welder is really good at this man.), then Download & install Facebook (Lite) Latest Version 1.11.1.92.209 Direct Link, not from playstore or search for it yourself. But when side loading, you must agree or not agree to let Google monitor it (Else the installation will never finish) and update the app manually yourself. Since FB Lite works perfectly and is not a system hog, there is not much of a reason to constantly update it, aside from any new features added that you might want.

[MENTION=5057697]welder73[/MENTION] I am copying this information into my Lollipop files because this is a valuable tip worth archiving. I hope that you do not mind, my friend. I keep tips from members here that I find particularly valuable as text files ;)

Nice work and great advice [MENTION=1472623]d.casper.b[/MENTION] and [MENTION=5057697]welder73[/MENTION]! :good:
