[Sprint HTC One (M9)] mammothjojo88:
This a short list of frequently asked questions in this device forum and the answers often given as a response. It should serve as a starting point for gathering knowledge and finding solutions to many common problems. Please only post in this thread with feedback on how to improve this document.

1: Difference between "Development" and "Original Development"?

Some of you may know but for the New Members out there...

Here are the rough guidelines as to what should be placed in "Original Development":

*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".

7: How can I enter bootloader mode & recovery mode?

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.

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..

REMEMBER: Your Bootloader Must be unlocked..

8: ADB. What is it?

Find out everything you need to know by reading the following thread - ADB Workshop and Guide for everyone.

Also I would suggest downloading Android-SDK and check for updates regularly

9: Should i backup my ROM before flashing anything else?

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..

You have the option to back up via HTC Backup in the Settings Portion of the phone. SETTINGS>Backup and Restore(or Reset)> Backup now. Or use TWRP Recovery to back up your Rom itself.

10: How can I S-OFF my device?

11: I have a custom recovery installed but I can't boot into recovery...

Use the command - fastboot erase cache.

You should now be able to boot into recovery

12: I don't like Blinkfeed. Can I get rid of it?

You can use a third party launcher such as Apex,Nova,ect.

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..

13: How would i be able to change my PRL?

14: How can I remove unwanted bloat?

15: I need to return my device back to stock?

16: Can I flash Roms from the HTC One(M9) International forums?

If they are in the Sprint section or say they have Sprint support you should be ok to flash (If it's not from the Sprint section please confirm in the thread it's Sprint compatible).

17: I just flashed a Rom and would like to see if i can flash a kernel with it.

Here you will find all the available kernels that are for your Sprint M9.

DO NOT FLASH A KERNEL IF IT STATES IT AS GSM OR NO SPRINT SUPPORT...

you could potentially Hard Brick your Device..
