Help with rooting Htc M8 marshmallow

Hi,
So I'm new to these forums and have been browsing all of the rooting guides for my HTC M8. I am running official Marshmallow and really want to root my phone (again) as far I know I have unlocked boot loader. I had to factory reset my phone last year and never got round to re rooting, but now with marshmallow I wish to do so again.
My issue is I can't seem to understand the steps the guides are outlining. I download the links and try and open them, but nothing happens. Is there a step by step fluid guide in rooting my phone? As all the guides I have found have basically blown over my head. I used a toolkit in the past which did everything for me automatically. If no such post exists would someone be able to explain the steps in a simplified manner? (If possible)
Many thanks in advance to any who help

This is easy to determine definitely. Boot into bootloader (if you don't know how, ask and I'll explain) and it will either say bootloader is: LOCKED, UNLOCKED or RELOCKED near the top of the screen.
Vomer's guide is dated at this point, but mostly still accurate for what you want to do (root MM); and its the best guide I know of: http://forum.xda-developers.com/htc-one-m8/general/vomerguides-m8-bootldr-unlock-s-off-t2800727
If your bootloader is UNLOCKED, you can skip the whole section on unlocking it, and pick back up the guide again where it says CUSTOM RECOVERY. If the bootloader is LOCKED or RELOCKED, you'll need to do the section for unlocking the bootloader.
AFAIK, the only part of Steps 0 and 1 that is out of date, is the TWRP version. For MM, you should use TWRP 3.0. And somewhat obviously, the fastboot command to flash TWRP will need to have the corresponding file name; rather than the old version number given in the guide's example.
You'll also want to use SuperSU 2.76 (if the SuperSU version is too old, it will fail to root MM and leave you stuck with no boot). But the guide is already rigged to link to the latest stable version (not a particular version number), so presently it already links to 2.76.
Don't continue to Step 2 of the guide. Its not longer accurate, and not needed for root.

Thanks for posting, couldn't find an up-to-date tutorial anywhere.
TWRP is asking to keep system read-only and I'm confused. If I allow modificaions, can I automatically never receive OTA updates again?
Will there even be another one for the M8/ will it get Nougat? Anyways, can I still root it with read-only?

You need to allow modifications for root. At least traditional root. Systemless root, I would think would work if you stay read only - but do the research especially if you don't know the difference between traditional root and systemless root.
You can't install OTA updates with a rooted device in any case, so that point is irrelevant.
If/when ever an OTA comes, you would need to return to stock never rooted ROM and stock recovery, in order to OTA update (there are guides on this forum). This would remove any modification by TWRP.
But that's mostly just FYI/academic. Its extremely unlikely we'll get an OTA update to Nougat. Your best bet for Nougat will be custom ROMs, anyway.

1. UNLOCK bootloader with HTC Dev site.
2. Flash latest twrp recovery
3. Flash Stable v2.65 SuperSU
4. Flash wp mod.
5. Update SuperSU on Play Store.
Latest SuperSU 2.76 zip kills Boomsound. Permissive zip can fix that.

Need Help - New to this

Hello. I'm pretty terrible at all this rooting stuff (or at least, I only do it once for each android phone I get, and then don't really look into it or stay up to date on all of it afterwards, I just use a few pluses that come along with being rooted).... Anyways, I really do need some help this time, as the confusion has really gotten to me, and I've lacked being able to find some simple answers (probably because they are just THAT simple) on google/reddit/on this forum.
Anyways, I've rooted my phone awhile back, lost it when my verizon pixel auto updated to 7.1.1 (idk how or why, pretty sure I had that disabled with root even, very frustrated) and even attempted to regain root by flashing SU with TWRP, but for some reason SU said I didn't have root still, and eventually just gave up in frustration. But now, my verizon pixel has been shutting off at ~40% battery power, and I read in the google forums that this was patched in the 7.1.2 update for pixels, and it was a software glitch rather than a malfunctioning/bad battery... So now I really want to upgrade to 7.1.2 from 7.1.1 not only to fix the battery/software issue, but also because I really want root.
I have an unlocked bootloader from when i first got my pixel and did this stuff, but now im unrooted on 7.1.1 because of that update awhile back, and want to update to 7.1.2 and root, but I've heard theres issues with rooting on the verizon because of bootloader, but that shoulden't be an issue since I unlocked it already (right? at least, I think? please let me know).
My only question (since i think i'll be able to follow this guide once I get the answer to this) is in the post he says: "Works with 7.1.2 (NJH47F, Aug 2017)".......... but since i have the verizon pixel (small version, not XL), should i be downloading this version: 7.1.2 (NHG47Q, Aug 2017, Verizon).... Or would it just be acceptable to allow my phone to auto download the update i have on it right now? Or must I download the NON verizon version as stated in the post and flash that one? Thanks for the help guys!
Thanks for any help!

If your bootloader is actually unlocked then no update that you flash can lock it. The people that were having problems on Verizon had phones where the OEM Unlock option was there and then after a Verizon update was greyed out. But those people didn't have unlocked bootloaders. Once the bootloader on the phone is unlocked Verizon can't lock it again.
The Pixel phone isn't really a good one to root once and then forget about it because sometimes the instructions change--people needed to flash a boot signature file one month to maintain root but didn't need to do it anymore the following month. Sometimes a particular version of SU stops working after an update and you have to download a newer version. The Pixel isn't like a Nexus where flashing and rooting was simple and easy.
I don't know of any reason you wouldn't be able to root after flashing a Verizon image as long as your bootloader is unlocked but someone with experience rooting a Verizon phone would be better able to answer that.

Thank you so much for the explanation. Truly, it's actually crazy how I was unable to find all of this neatly, nicely, and simply stated. Great to hear, I'm going to go on rooting, here's to hoping I don't blow it up.

unlocking bootloader and rooting.

So I just got the pixel xl 128 gb from Google because my nexus 6p had the battery issue. Just got this sucker turned on and I realized it is still on April security patch with 7.1.2. Now I am Verizon but didn't get it from a Verizon store so this should be unlockable correct? Where is the easiest method to unlock and flash twrp? I used magisk systemless on the 6p. Noticed pixel is a different beast. Can someone help me or at least guide me to the correct places since everything is so buried now with android O out and stuff. Thank you!

You should be ok with unlocked device from Google.
Magisk method doesn't work yet on PixeXL...coming soon.
We also don't have a flashable TWRP for Oreo. Guess we have to fastboot into it.
There seem to be 2 threads in this Guide form detailing unlock/root for Oreo. Haven't figured out which one to use yet.

Ya everything is much different. I'm avoiding the update as I hope I can unlock the bootloader and root on 7.1.2 thank you though!

Just throw the switch and then do what you want. The update has nothing to do with it.

This guide is the easiest to follow.
I am in the same boat as you and after some researching it's fairly straight forward. Don't root or flash a kernel via fastboot, that is the outdated method, use TWRP.
Follow the guide. The biggest thing is flashing RC2. Magisk isn't working, don't even bother with it until it's updated, use SuperSU for the time being. From what I've read Magisk is close to being done.
When flashing ROMs or anything via twrp, keep an eye on which slot is active (go to reboot in twrp, it will tell you which slot is active) If you flash something and it boots back to twrp, reboot into the other slot and try restarting the system.
The biggest thing is to not mess with installing/flashing stuff when you're not around a computer you can use fastboot on. You might get stuck with a non-booting phone or not have TWRP to boot into and would need to fastboot into the RC1.img

Just bought a Pixel on 7.1.1, safe to update to 8.0?

Pretty self explanatory. I have the update pending for 8.0 but I've heard mixed reviews of the Oreo updates. So please, if anyone can be honest and tell me weather to proceed, or should I wait and why. Thanks you.

If it's a Verizon model you just have a gem in your hands, look on how to unlock the bootloader before update, if it's a Google version, then all you get are improvements and new features without compromises.

What's the best way to check if it's Verizon? And I don't need to root or anything honestly. I'm asking if the bugs with 8.0 are worth updating at the current state.

I recommend unlocking bootloader first and then update

So by unlocking the bootloader, I won't run into problems taking official updates?

No. If you modify system (root, Magisk, custom ROMs/kernels, TWRP recovery, etc) then you won't be able to take official OTA updates. But you can take them just fine with an unlocked bootloader.
Also, I'm on stock 8.1 and have no issues to speak of. I say go for it.

FYI If phone is a Verizon version an on 7.1.1 you are able to unlock it. If you update beyond 7.1.1 without unlocking you will Never be able to unlock it. If it's a Google version no worries.

There's no reason to unlock the bootloader if you're not rooting. That's just introducing a security issue. The Oreo update is safe and stable to install. You're good to go on hitting that update button.

I disagree. On rare occasion, the OTA update can cause issues, and with a locked bootloader you are unable to install an image. Even if I don't root my devices, I still unlock the bootloader just so I can have the option of installing a factory image just in case something goes wrong.

He's right though. Unlocking will lead to security issues and may take away the ability to use important apps. If he prioritizes functionality, then it's best to keep it locked but if he wants to tinker, it'll come with compromises.
Since he just bought it, I don't see why he couldn't just warranty it if an update goes wrong, which is extremely rare. From what I've seen from people with bricked devices, the majority of them were unlocked and tried to update using non-conventional ways.
Bootloaders are locked from factory for a reason, not for inconvenience.

Going back to stock help (Re-locking bootloader)

I want to upgrade to the Pixel 3 XL and give my mum my Pixel 2 XL because she loves the camera on it.
I'm currently rooted and running Havoc, I want to re-lock the bootloader and I know you need to be complete stock to do that.
Just curious is the procedure I need to do as simple as:
1: Clean flash latest factory image
2: Re-lock bootloader
Is it really that easy?
I know Re-locking the bootloader is a very easy way to hard brick your phone, and so I don't want to do anything wrong
Any help is appreciated and thank you in advanced

Just flash stock img and give her the device. Considering thel multiple threads of issues others are having relocking the bootloader and since you're giving it to your mom, I'd recommend leaving it unlocked. At least for now

YES....LEAVE IT UNLOCKED!! Your mum will never know

She'll get that obnoxious warning about the bootloader being unlocked if she restarts the device. Other than that, I totally concur with leaving it unlocked.

yes i would also say leave it unlocked but there are some limitations to stock and unlocked like google pay not working without a modified kernel the same for some bank apps and others too
