Q1: What's the difference between "Development" and "Original Development"?
Here are the rough guidelines as to what should be placed in "Original Development":Q2: I'm new to all this rooting and modding stuff where should I start?
*Official release of highly original and upstream custom ROMs (built from the ground up with significant original development within them).
*Official releases/development of such original ROMs, perhaps posted by the maintainer or their nominated person.
*A significant "first" in development for a device. This is something which took considerable time/effort and is generally accepted by developers to be non-trivial.
*Kernels which are built with beneficial changes that are not simply pulled from other kernels already available.
*Tools and utilities with a clear purpose, and which are well-made, and useful to users. They should have an element of originality, either in purpose or through significant improvement in the means of operation.
*Significant port of a ROM from one device to another, giving enhanced features or functionality to the users of the target device.
All other development work goes into "Android Development".

What Is TWRP Recovery & How To Install & Use It On Android Devices [Guide]
To enter bootloader mode make sure your phone is turned off. Turn it back on while holding the 'volume down' button and you will successfully enter bootloader mode.Q8: I hear a lot about ADB. What is it?
*NOTE* Before you enter bootloader mode your bootloader must be unlocked. Unlock your bootloader by following the first part of this thread.
To enter recovery mode, you will need to enter the bootloader (as detailed above) then use the 'volume down' button to navigate to 'RECOVERY'. Press the power button to confirm your choice. You'll now be booted into your custom recovery..
Find out everything you need to know by reading the following thread - ADB Workshop and Guide for everyone.Q9: Am I required to backup my ROM before flashing anything else?
Also I would suggest downloading Android-SDK and check for updates regularly.

No you're not, but it is definitely a good idea because if you don't do a backup and then something goes wrong, it means that you'll lose all your apps, data etc. It just saves a lot of hassle..Q10: How can I S-OFF my device?

S-OFF explained - by a Developer Thank regaw_leinad
**NOTE USE AT YOUR OWN RISK THESE COULD POTENTIALLY BRICK YOUR DEVICE**
Use the command - fastboot erase cache.Q12: I don't like Blinkfeed. Can I get rid of it?
You should now be able to boot into recovery.
You can use a third party launcher such as Apex,Nova,ect.Q13: How can I change my PRL?
Or long press any screen and choose Add apps and widgets,then drag the blinkfeed screen to the top to remove.
One thing you can do, however, is to change Blinkfeed to a different screen so that it's out of the way and you won't have to see it as soon as you hit the Home button.

[Resource][Guide]Sprint HTC M8 Hboot versions & info Thanks Magnum_EnforcerQ25: Any way to turn on and off wifi calling with wifi?
This breaks ALL notifications from wifi calling but it doesn't break the functionality of calling itself. So when you're on wifi you just gotta trust that wifi calling is connected (or go into settings to see if it's on). Also it DOES break address confirmation but since this should only be a one time deal for most people you can just reenable the service when you need to confirm your address if you're adding a new network or simply want to re-confirm it. You also wont be able to turn the service on and off in settings, but since it's not a radio itself turning of wifi will kill any battery usage by wifi calling:
1. Get ROMtoolbox (I have the pro version so idk if it works on the free version)
2. Go into app manager
3. Find and open wifi calling (make sure its NOT the one from htc)(also don't just select it, make sure you go into the menu)
4. Go right to the advanced section
5. Select advanced freeze
6. Find the service "vowifiservice"
7. Click on it to disable it and agree to the prompt
8. *optional* Reboot the phone or refresh the setting to clear any notifications currently showing
