thanx - For the quick reply - umm I have a Sprint version of the HTC m7 WLS - I tried installing the universal recorvery 3.1 twrp for it , it give me an error then I found a 3.1.1 version of twrp for HTC m7 Sprint from twrp site - I was just wondering if it's safe ...
How can I root back if recovery Mode goes to twrpDriver problems...get HTC Sync Manager HERE
Latest version of SuperSU can be found HERE
New official TWRP download page
If you are having issues with the "Official" TWRP in the folder I recommend this one... HERE
Those of you that insist on taking the OTA follow these steps:

How to go back to stock recovery after unlocking/TWRP/SU to take OTA update and how to revert back afterwards:
This assumes you have used this procedure to root phone. Doesn’t mean this procedure won’t work if you have used variants of that method or a different method, but whether these steps will work if that’s the case I don’t know.
1. Turn phone off
2. Boot into bootloader
3. Choose fastboot
4. Connect phone to computer through USB cable
5. Open elevated command prompt and navigate to folder where the stock recovery is located
6. Type at prompt: “fastboot flash recovery filename.img” without the quotation marks (where filename is the name of the stock recovery image you want to flash). You’ll see something like this:
C:\RootM8 (1)>fastboot flash recovery stockrec.img
target reported max download size of 1830711296 bytes
sending 'recovery' (24576 KB)...
OKAY [ 1.721s]
writing 'recovery'...
OKAY [ 1.106s]
finished. total time: 2.830s
7. Reboot phone
Your phone now has the stock recovery, and it’s still rooted, but not for long . You can now proceed to take OTA update, at which point you will probably lose root, and then follow original procedure to flash TWRP recovery again, and then root again.
Just a few notes on my experience:
Supersu
I was running stock lollipop 5.01 on a unmodified One M8. The readme doesn't say anything about supersu like OP says it does. I figured that one out (just flash supersu using twrp). But a problem came with using the supersu in the zip file from the OP. After flashing it, when I ran supersu, it said the binary wasn't present and that it could not install it. I finally figured out I could use a latest beta version of supersu (2.47 I believe). I guess older versions maybe don't support lollipop?
HTC drivers (and HTC sync manager)
The ones in the root zip from the OP didn't work for me. They said they installed (64-bit ones for my win8.1 computer), but they didn't appear to be working. Once I installed the HTC sync manager, that worked. Guess it installed the right drivers or at the very least was needed in conjunction with the drivers in the zip from the OP? Really not sure.
ADB
I know fastboot.exe requires the adb dll but does it require adb.exe? I didn't see a need in this particular procedure for adb.exe, and the OP says that the readme mentions using ADB commands (instead of fastboot commands). Nitpicky, I know, but could be confusing for some.
TWRP
Also, I'd recommend getting the latest twrp instead of using the one in the zip file of the OP (the readme does mention where to get the latest), especially if you're already running stock lollipop 5.xx. I didn't have any problems with the twrp in the zip file from the OP, though. I just thought it was a good idea to run the latest twrp after the problem with supersu and lollipop, especially since I'll be using TWRP for backups (and restores) of lollipop.
Thanks for the instructions and packaged zip.
Well right now no permanent changes can be made to system, unless done from recovery. S-OFF will certainly remedy that, as well as allow for the red disclaimer and tampered flags to be removed.Cool, thanks for putting all this together. I'm not sure it's worth doing it this early if S-OFF may be coming soon...at least by the time some more ROMs show up.
