n00b needs help!!!

I'm a semi-experienced android-er, I've rooted several devices and understand how Roms, Recovery, Odin, EFS Pro, Cygwin, etc.. work and what to do with them. I can't however, figure out how to root my Verizon S4 (lollipop) OR install a custom recovery mod. I have a stock .md5 that I can flash with Odin - I've tried modifying the PIT file and swapping recovery img's etc... and everything goes smoothly untill I get to the modified file and then I get an auth error. Can anyone help me get past this?

Is the nexus the right option for my needs?

First off, thanks for your time.

I am thinking about buying the nexus media player now that it is only . My other option was getting a rasberry pi.

My main goal is I want to use it for emulators to play old roms. There are plenty of good emulators in the play store and I can just sideload them. I would also like it to have plex which I know it does.

If I go with the Raspberry pi I can just load retropi on it but I'm not sure if I can then use plex.

Lastly is the controller- http://forum.xda-developers.com/nexu...llers-t2973028
That convenient thread lists potential options.
I already have a wii u pro controller. I googled to see if it is compatible and did not find any clear answers. Do you guys have any experience with this or know If I can just buy a bluetooth dongle and usb adapter to get it to work? Will this dongle work on the raspberry pi?

If this doesnt work I can always get the 16 dollar Nyko Play Pad Pro that it supposed to work with this

Overall which option do you guys think is the cheapest/most convenient for me?
Is there another system out there that I am not thinking about that would be an even better option?

Thanks again

G2 Possibly Needs New Motherboard Or?

Hi guys..

So I bought a LG G2 used on eBay. It was for 50 bucks or so and it was cheap because it didn't have a screen but the seller stated everything else works.

So heres what I did:
Purchased new screen x 2 (twice)
Both screens didn't work
Connected phone to TV through an HDMI adapter
The phone heats up while it's booting up sometimes

I can see the phone screen on the TV but the screen doesn't light up at all except it does have a tiny bit of backlight. As I touch the screen, it goes VERY slow, takes a second or two to respond.

How do I know if it needs a new motherboard or just new parts?
If it goes very slow but it shows on the TV, does that mean the motherboard is the issue?

Thanks in advance!!

Galaxy S6 Can't root as it needs "Unlock" first

Hi team,
I have just successfully rooted my Galaxy S4 and wanted to continue with me new S6 Model SM-G9200. When pressing the buttons to go into download mode, the screen turns light blue with a message to "Unlock" the phone first and ask Samsung.com/cn (which of course is pointless). The phone has no Sim lock and I really wonder if anyone had the same problem and how to solve it.
Carrier is China Mobile Hong Kong.
Thanks for any advice you may have.
Cheers!
