G900A Unrooted: Error -505 Downloading Facebook Messenger Fail

No matter what I seem to do, i cannot successfully install Messenger. It downloads perfectly fine, but then it fails and gives me error -505. Cant find anything about an error -505. Cleared data on google play, uninstalled its updates, cleared whole phones cache, uninstalled previous version of messenger, restarted phone, and nothing will allow me to install it. Have 3GB of free space internal.

(Excuse me for posting two different threads. Did not want either situation overlooked.)

[Q] Downloading source code by .zip archive

Hi,
I was trying to download the source code of a ROM but I was stuck at 98% so I thought download using a .zip archive. Now I have the file but I'm not sure where to place the 'extracted folder' in the ROM directory. Can anyone guide me where to place the extracted folder? It's android_frameworks_base.

Free Mp3 downloading apps won't work on new phone! Help!!

I used to use music paradise download pro on my droid maxx hd. Now I have a new droid turbo rooted on 4.4.4 and none of the music downloading apps will work at all on my phone. Is there something blocking it that I could freeze or something? I loved music paradise pro and now I don't know how to operate without it.
