Basic Mods Questions- Unlock, Root, AdAway, Tether, TWRP

When I get phone I'm most interested in doing build prop edit for tether, installing custom recovery TWRP for 6P and AdAway would be nice. Loss of Google Pay not a show stopper. Would like to do OTA factory image updates or modified images until custom ROMs and Kernels mature.
Can someone please post idiot proof specific instructions or guide links. I know some basics but assume others do not.
Thanks

Verizon Basic Visual Voicemail

Can anyone get voicemaill to work on Verizon on their 5x? I just get a garbled text message when a voicemail comes in. There is a nexus visual voicemail app but it hangs on authentication when going into it. I guess I can call Verizon and have them switch back to regular dial in voicemail.....

Help - No helpful tutorials for basic stuff?

Hey guys, ordered my first Pi today, should be here very soon! I've got the media center ready, (Using a portable HDD with a powered hub) Will be installing Kodi, OSMC with the supplied n00Bs SD card that comes with the package. That's all sorted "I think" should be quite easy.

I've just put Recalbox on a SD Card ready to also install and then I can run both recalbox and my media center at different times. using both SD Cards.

I have a slight problem though, I don't think I'll be able to network into the Pi, to put the ROMs into the proper folders, So how do I put the games onto the SD card? Can I just take the SD card out of the Pi and put it into my laptop and transfer the ROMs??

With Neo Geo, What do I do to get anything working at all? I've downloaded "piFBA" But I just can't find ANYTHING thats even remotely user friendly tutorial for a newbie with Linux etc on what to put where, It's like they just expect EVERYONE to know exactly what to do, And I'm quite PC savvy in some sense, so I'm a little dumb founded why I'm struggling to find much info, Is the Pi just not that popular ? I really don't know.

I "think?" I'll be fine with everything installing, but I think I may be stuck with the roms, and putting them into folders etc. I've even pre scraped the games to get it ready and make it a quicker install!

I also think I'm going to have problems with Mame/NeoGeo.

I'd love some help ! Or a link to a super easy informative tutorial on a step by step guide on exactly what to do.

I think I've defiantly decided on recalbox over retropie and emulation station, I just love the simplicity it's offering, and for now I think it'll be a good choice...

But I'm so lost and confused, I can't seem to find much help.

Basic Q: PingPong Root my AOE2 S6 Edge and flash custom ROM based on 5.1.1?

Hi,

This is a very basic question, but I haven't been able to find the answer in one place.

I have a new Galaxy S6 Edge G925A on AT&T, baseband version G925AUCU1AOE2. I don't want to take the OTA update because apparently then the bootloader will be locked and can't be rolled back. I'd like to root the phone and not lose any features but I'd also be able to flash a ROM based on the most current version of Android available (and continue to upgrade in the future). Right now I only know enough about rooting, bootloader, baseband, kernels, custom recovery, ROMs, Android, KNOX, radios, modems, fingerprint scanners, Samsung Pay . . . to be dangerous. Every search I've done over the past couple days seems to teach me something while also confusing me a little bit more.

What I'm wondering is - if I root my AOE2, am I then able to flash a custom ROM based on 5.1.1 (or later) versions of Android without losing any other features (Samsung Pay, fingerprint scanner, etc.) and without locking myself to a certain version of Android? If so, what steps would I have to take (e.g., 1) root, 2) install a custom recovery, 3) flash a later kernel, 4) flash ROM, etc.)? Thanks in advance, and sorry if this question is answered elsewhere already!
