[T-Mobile HTC One (M8)] RockStar2005:
Follow these videos IN ORDER to achieve complete awesomeness on your M8 phone. This guy is great and doesn't rush through anything.

IMPORTANT ITEMS: DO NOT attempt to do any of these if you have downloaded ANY OTA updates already. Check Settings, About, Software Information. T-Mobile Software # should be 1.12 or 1.14 (under 1.2). If it is, proceed. If it's at like 1.5 or higher, DO NOT proceed. Instead, check here https://www.google.com/webhp?source...e=UTF-8#q=how do i downgrade my android phone to see if you can downgrade your Android version back down to 1.12/1.14. IF you succeed, THEN continue on. If not, then don't.

Also, make sure you're NOT using a USB 3.0 connection to the phone AT ANY TIME. USB 2.0 only, and if you got a Mac, then check here https://www.youtube.com/playlist?list=PLHTorDR_h9wzlSNE_Ewoy6LpjXrTiEo3F for rooting (includes unlocking I think? s-off for mac....check elsewhere). These videos are all for PC only.

1) Unlock phone: https://www.youtube.com/watch?v=rEVSfwXsx-c&list=PLHTorDR_h9wzlSNE_Ewoy6LpjXrTiEo3F&index=3

2) Root phone (will erase all memory, so make sure you backup as instructed): https://www.youtube.com/watch?v=WuHFcGvUjwA&list=PLHTorDR_h9wzlSNE_Ewoy6LpjXrTiEo3F&index=4

3) S-Off phone (gives you more flexibility and in some cases is required for some mods to work I believe. You may have to repeat it a few times for it work): https://www.youtube.com/watch?v=--Hlms1BuPg&list=PLHTorDR_h9wzlSNE_Ewoy6LpjXrTiEo3F&index=2

4) Get OTA updates on a rooted phone (Rooted phones REQUIRE extra steps in order to get new OTA updates. I've saved this video in my Bookmarks for when future updates are made available, and I highly recommend doing the same. You'll STILL get update notifications though, so don't worry.): https://www.youtube.com/watch?v=PPPT5J8xG6w&index=15&list=PLHTorDR_h9wzlSNE_Ewoy6LpjXrTiEo3F

Now you can do basically anything you want with your phone, grab any MOD you like, etc. Like get H/K (below) or the Sense 6 Toolbox in order to disable swipe to wake but keep double-tap to wake, etc ( http://xdaforums.com/showthread.php?t=2713939&page=38 , see my post, #376)

And the optional #5: To get Harmon/Kardon sound on your T-Mobile HTC One M8 (which is more powerful and more clear than BoomSound), then check here. I have it (S-Off version) and it's FANTASTIC! If you've done Steps 1-4 above (Step 3 is not necessary for this, but recommended), then just skip to Section IV and follow that. Again, I recommend doing Step 3 above too first before this. If you don't, then you'll need the S-ON version (see link below).

And yes, PowerAmp on "Rock" preset with DVC and Bluetooth DVC TURNED OFF in settings (Audio, Advanced Tweaks), as well as Audio Buffer Size and Thread Priority set to highest # listed. Look and Feel: Status/Bar Notif.....check "<< In Notification" box and same in General (<< Button Resets Current Track & Delete Action checked). I keep Lockscreen for PowerAmp off.

If you would like screenshots of my calibrated EQ settings, just reply to this post. They're both based off of the "Rock" preset with Limit OFF.
