Yea, you will need to update your files. And I guess tubehax is fine, that I'm not sure of. People have mentioned another one lately, but I don't know the name.
I'd recommend
Kafluke's package, but I'm not sure if your webserver on the phone supports PHP. easiest way to find out is to try though. As far as not working online, I had that issue a lot with 5.3.2, but it doesn't really seem to be the case anymore using the stagefright exploit. I've never had one failure using loadiine.ovh. wiiubru.com/x includes a small wait timer like loadiine.ovh does so I'd imagine success rate is fairly similar if not the same.
Oh, I did have to do the browser's "Save Data Reset" in it's own setting menu where you can delete cookies and change search provider. Other than that tho, just worked.
