Sure you can download it and extract OR you can just go COLLECTION of Stock backup's and download the stock recovery. Both the 2.22.709.3 and 2.22.709.4 is in that thread.
Flash back the stock recovery and lock bootloader seeing as you're S-ON. Do the update and you can go ahead and do what you want again. You'll probably lose root yes, you can just get it back again no problem.
Edit: Not needed to relock bootloader as mentioned by ckpv5 :good: :victory:

There is no need to extract the stock recovery from the OTA, we have stock recovery 2.22.709.3 and 2.22.709.4 here : http://forum.xda-developers.com/showthread.php?t=2701376
There is no need to unroot as you will lose root anyway with the update, then you need to re-root
And most important is there is no need to lock bootloader. Leave it unlocked.

You beat me this time
But I need to correct one thing, there is no need to relock bootloader for OTA whether it's S-On or S-Off.
Relock bootloader for S-On is needed only when flashing signed htc firmware or run RUU

Ah ok, I can remember in the stock collection thread it was mentioned that we needed to relock if S-ON, I did see someone else say different but wasn't sure about it. That's cool then. :good:

another 2 really quick questions:
1 - My HTC wont go into debugging mode. i enable it, there is that little window popping and saying if i want to accept this computer, i checked "YES", and then nothing happends. even ADB Devices wont recognize.
2 - You guys recommend s-off? whenever HTC releases Android L, having S - Off would be good or bad?

Yeah ... many times people say this ... until Mr Hofs himself ask one fellow from where he got the info that need to relock bootloader for OTA
See this for example : http://forum.xda-developers.com/showpost.php?p=55148300&postcount=3

1. make sure your ADB version is not lower than 1.0.31
2. S-Off is good and bad..
good for people who knows what he is doing
and bad for people who doesn't know what he is doing as he can easily brick his device.
When HTC release Android L... it got nothing to do with S-On or S-Off

You are not reading.....it's been said 2 times at least :
1: you do NOT have to relock for an ota !
2: what you need is
- stock rom with UNMODIFIED system (root is NO issue)
- stock kernel (boot.img)
- stock recovery
Then you can update !

Hello guys, anyone knows where can I download the stock recovery 2.22.709.4? I can't find the file in the link that ckpv5 share:

THANK YOU SO MUCH FOR THE RECOVERY'S
I don't know if this question goes here, if not im sorry
I follow a video tutorial: how-to-get-ota-updates-on-a-rooted-htc-one-m8

My HTC M8 has the cidnum: HTC__621 that's the reason that i need the stock recovery 2.22.709.4 so... I flashed the stock recovery and i get this results from adb:

It's nothing wrong, that's the stock recovery.
You're not supposed to reboot in recovery mode.
Just reboot your device, check for OTA and let the system do everything for you.
Do you have the correct stock ROM for your current firmware ?

This is the reason why you have that problem device not booting.
You can't use a very low version recovery like 2.22.709.4, it won't work.
You can use only 4.24.709.2 recovery and nandroid backup or in case you want to go lower to do OTA again, you can use only the lowest is 4.16.709.9 recovery and nandroid backup. Cannot go more than one version lower.
Do you still have the current ROM 4.24.709.2 backup ?
What was the problem with 4.24.709.2 that you seek advise from some people who simply give wrong advise ? Yours is the latest update lollipop 5.0.2 .. remember that.
You can try the one posted here : http://forum.xda-developers.com/showpost.php?p=59953829&postcount=5068
See whether you can download it or not.
If cannot, I will see whether I have time to upload my own backup for 4.24.709.2

OHHHH
I don't have any problem with 4.24.709.2 like you said I just received wrong advice
I don't have the ROM 4.24.709.2 backup, I will try to download the file with the link that you provided me, once the file was downloaded I just need to flash with TWRP is correct?

I have no idea about that backup whether it is for TWRP or CWM. But backup is for restore not flash. Unzip on PC and transfer to custom recovery backup folder. Boot to recovery then restore the transferred backup
I don't understand why you flashed the wrong stock recovery when your latest ROM has no problem.

[Q] Go back to stock

Hi there.
I was wondering if anyone could help me. I want to go back to stock recovery to perform an OTA (4.4.4). I'm currently using ViperOne m8 2.5. My Cid is called HTC_Y13. But I couldn't find it anywhere.
What to do?
I'm Danish by the way. My phone is a One M8 and I believe it's the international model..

here's the steps to get you back to stock
download this > https://mega.co.nz/#!VcZAgIgT!flJca5C_hRl6pgAn5EXp4qbJCl0ONjZB8PHNylw5f3Y
while it's downloading go into TWRP and choose Backup
uncheck everything except boot ... do the backup
this will create a folder on your sdcard TWRP/BACKUPS/your_Serial_no/Todays date
when the download is complete extract it to the Todays date folder. Make sure it's just files in the folder and no folders
now boot back to TWRP and choose restore and restore the backup / make sure system and boot are checked.
the last step is to put back the stock recovery
use this one > http://d-h.st/WB4
you flash it the same as TWRP
fastboot flash recovery recovery.img
fastboot erase cache
fastboot reboot
your phone should now be back to stock and ready for OTA update

COLLECTION of Stock backup's
Your CID is HTC__Y13 you can download any x.xx.401.x backup from that thread.
The WWE (World Wide English) nandroid backups have the same main version build numbers. All these nands have the main number that is based on the x.xx.401.xx build and all these CIDS are compatible
HTC__001
HTC__E11
HTC__102
HTC__203
HTC__405
HTC__Y13 <<<THERE IS YOUR CID
HTC__304
HTC__A07
HTC__002
HTC__016
HTC__032
HTC__J15
HTC__M27
HTC__A48
HTC__K18
Click to expand...
Click to collapse
Download any x.xx.401.x backup (HTC__001 will be fine) and backup through correct custom recovery(Philz if it was Philz, TWRP if it was a TWRP created backup).
You can also download any x.xx.401.x stock recovery for your device OR you can grab the latest stock recovery from the OTA(Copy OTA.zip to your PC and extract the recovery.img file inside the firmware.zip).

Returning Stock
I'm also a little bit confuse with all information. I've been tryng to solve my ROM problem about 2 days.
I have flashed the ARHD 21.0 on my phone but a lot of errors are happening (common ones like no Wi-fi and other more annoying like extended reboot time). I'm trying to get back to the stock ROM to perform a update of my firmware but I'm kind of very lost in the forum.
My getvar is like:

I'm very afraid to flash something wrong because everything went wrong with me. What version should I flash? I guess my phone is the International version (since I'm a brazilian and HTC don't sell phones here)
Thanks in advance.

No I guess your phone is an International version, not because you're Brazillian but because your CID says "HTC__001" which is International. Like You no doubt read in the 2 posts just above yours, download a nandroid backup for your device and restore it via the correct custom recovery. I even put a link to the thread with the nandroid collection in my first post here!!!
Just download the nandroid for your device, it'll be the 1.54.401.x backup seeing as you're still on the 3.16bootloader. 3.18 was 4.4.3 and 4.4.4 is 3.19 so you're probably still on 1.54.401.x. Download the 1.54.401 backup and restore in custom recovery. Afterwards just flash back the stock recovery.img
Make sure recovery.img is in your adb folder and boot into bootloader and use fastboot flash recovery recovery.img <That'll give you stock recovery again and you can reboot back into OS and download/install and update the OTA/Firmware as it comes all the way to 3.28.401.6/7

Sorry man, but I did. I read the post before mine. But I like I said, I'm trying to do this about 2 days and everything went wrong, so I thought that the version HTC__Y13 could have a different procedure that HTC__001.
I'm not the kind of user that thinks the problem is just happening to him. I read a lot of things but seems that more I read, more doubt I get.
Anyway, thank you very much for the fast answer. I will try what you said. :good:
Just one doubt. My ROM is 4.4.4 and my bootloader is 3.16. Is this wrong?

Yes, the 4.4.4 ROM MUST have 3.28.xxx.x firmware in order to function properly. You're still on much older firmware which is why you have excessively long boot up times, wifi/data problems(Outdated radio) etc. In order for the ARHD 21.0 to work correctly you must be on the correct firmware(4.4.4 android version, 3.28.401.6/7 <<<If you're international version which you are). This has been the case for some time now, you can do an easy google search "htc one m8 xda ..." along with something like "slow boot up" etc and you'll see that all of them had the same problems, outdated firmware.
Which is why you'll have to go back to stock and do the OTA updates as it comes. If you were S-OFF you could have done it manually and flashed the firmware manually but since you're S-ON you can't do it. Flashing Radio firmware you'll need to either be a) S-OFF or b) Official HTC OTA.

Thanks man! I'm now on 3.28.401.6.
Before your post, I hadn't understood that I needed restore from 1.54.401.x backup (I almost restore 3.28.401.7).
Firewater didn't work in my device, so I have to pay $25 to be S-OFF (and $25 is a lot of money when converting to reais - currency of Brazil)
I will come back tomorrow to give you Thanks (reach my max today).
PS: The 3.28.401.7 update didn't arrive to my device.

Confused!!!
I'm really confused!! I'm not that hardcore at all..
All i want is to update from 4.4.3 to 4.4.4 so I can Update from ViperOne 2.5 to 3.0.
I tried to flash a Stock Recovery called "stock_recovery_1.54.401.5_recovery.img" and I think it succeeded. Hard to see a difference. But I followed a guide made by Sakitech on Youtube. Then I searched for any updates. But it said "No update currently available". So I just flashed the custom Recovery again.
Sorry.. But I'm a Dummy

I am having some major issues too. Im just wanting to go back to stock so I can use sunshine to S-off my phone. My CID is ORANG001 so i got a nandroid backup 1.54.61.5 which is the correct stock and the corresponding stock recovery, all went well but not only does Sunshine still refuse to work, if i take any OTA updates, the first installs ok but then my wifi wont work, ie the switch will not turn green it just goes grey, any ideas!!?!!?

I'm really confused!! I'm not that hardcore at all..
All i want is to update from 4.4.3 to 4.4.4 so I can Update from ViperOne 2.5 to 3.0.
I tried to flash a Stock Recovery called "stock_recovery_1.54.401.5_recovery.img" and I think it succeeded. Hard to see a difference. But I followed a guide made by Sakitech on Youtube. Then I searched for any updates. But it said "No update currently available". So I just flashed the custom Recovery again.

I think I can help you. After all my mistakes, I think I have learn something.
To update to 4.4.4 (and for ViperOne 3.0) you need to update your firmware first. To do that, you have 3 options:
1) S-OFF and update your firmware by flashing a simple file.
2) S-ON and search your EXACTLY modelid and cidnum on this thread
3) -That one BerndM14 help me in previous posts - Check your firmware and return your phone (ROM and Recovery) to stock basing on firmware version. This post explain better.
Like BerndM14 said to you, it is just necessary you to download any x.xx.401.x backup AND any x.xx.401.x stock recovery. After that, follow the instructions of the second question of the post. You will unzip the backup and inside, find a file called 'boot.emmc.win' or 'boot.win'. You have to flash this (fastboot), do a full wipe and then restore the backup (custom recovery). After all you return to bootloader (rebooting) and flash the recovery with this:
fastboot flash recovery <recoveryName>
That it. At least, what I understand. Any advanced user could confirm this informations?

I think I got a Little closer now. Let med undrstand this S-OFF right. Does that make everything a lot easier??
I tried flashing Again yesterday, but without any luck. I downloaded a major stock backup zip file, but I'm not sure how to flash it. I wish I could Just hand it over to someone, but I vant find anyone here in Denmark who is cabable at doing this. ?.
I think The biggest problem is that i dont know where, when and what to flash ?

I think S-OFF let the things much more easier. My m8 is S-ON so I don't know a lot of this, but there is some tutorial about firewater. If this tool doesn't work for you (like happen to me), you will have to pay $25 for Sunshine. From what I read, this method is guaranteed to get S-OFF.
With S-OFF, you will find some posts with updates of the firmware. So you don't have to go back to stock to update it.
To continue from where you stop, you have to follow this post. Like I said before, download any x.xx.401.x backup AND any x.xx.401.x stock recovery and follow the instructions of "How do i restore the stock nandroid backup" question (same post).
You don't flash the major stock backup zip file. You RESTORE it, on your custom recovery (TWRP or Philz) according from which recovery the backup was made (for example, if you download this one: 1.54.401.5 - TWRP Thanks to Fisha21. This backup was made on TWRP so you have to restore it on TWRP. But before restore, you need to flash the "boot.img or boot.emmc.win" file that is INSIDE this backup zip file. After that you make a full wipe in recovery and then RESTORE the major backup (remember, you don't restore the zip file, you have to unzip it on your phone like is said on the "How do i restore the stock nandroid backup" question of the post).
After all, you will flash the recovery of the same version that you download on the same post.

You looked your firmware version, befere restore the 1.54.61.5 version? You have to check the CID AND the main version of your phone, like it said on the beggining of the post:

My main version number is 2.26.61.5 I think but I asked weather using 1.54.61.5 would be OK and was told it would be fine as its *.**.61.* based backup. Is this incorrect as they use a different firmware base?? Is this whats causing my issues??

I Flashed a file named boot.emmc.win from inside the unzipped backup. I moved the file to my adb_fastboot folder and flashed it this way: fastboot flash recovery boot.emmc.win
Then I had trouble gaining access to custom recovery (TWRP) so I tried flashing the custom recovery again. I got in! Made a full wipe, chose "install", twrp > BACKUPS > Serialnumber > Backup.zip. But it failed!!!!! It was missing a md5 file???
I'm starting to regret all this root-mess

You still have KitKat firmware, as shown by your OS version. You CANNOT flash a modified firmware package while S-On. You need to either run a signed RUU, or go back to stock and use HTC's/your carrier's OTA updates.

Do you have a stock ruu? or maybe how to s-off? because i cant find anywhere firewater.
Maybe this will help with something:

What firmware did you try to flash? It looks like it was GPE firmware.
Is your bootloader screen black or white now?

My bootloader screen it's black, it's that important?...
And the firmware was download from HDRevolution website.

Yup, that's very important. Black hboot screen is the GPE version (and white is Sense version hboot). You at least partially flashed a GPE firmware. This isn't supposed to happen with s-on (firmware for other versions should be blocked). But I do remember a while back, a few folks having the same issue; where a GPE firmware or RUU partially flashed (with s-on) and caused some problems.

That doesn't help. Quite a few firmwares are posted there. What specific number firmware did you flash? Did you flash the firmware number (3.11.1700.5) shown OS number on your hboot screen?

I don't know why you flashed this. Not only is it not current firmware (Kitkat, as another noted before), but its not even for your version (its GPE version firmware, as I mentioned).

That is the proper RUU for the AT&T version; and your bootloader is relocked, as it should be for RUU.
So I think the problem is the GPE firmware you flashed before.
Try flashing the proper firmware first, then RUU again, and hopefully that will work.
I can't find the 4.28.502.2 firmware. But 4.28.502.1 firmware is posted on the following. Use the Full stock firmware. Hopefully, this is close enough to 4.28.502.2 to work.

That RUU will not work, anyway. Its for the Developer Edition, so the only way to run it would be to change your CID (s-off required, and working OS is needed to s-off).

Firewater was discontinued by its devs in December 2014. Since it has an online component (needed to connect to servers), it won't work even if you find the firewater binary.
Sunshine is the only current working s-off method, and as I mentioned, it requires a working OS to work.

Yes, firmware needs to have the same CID and MID. But the 3.11.1700.5 firmware doesn't go with your CID and MID (CWS__001 and 0P6B12000)
"1700" firmwares (such as 3.11.1700.5) are for the Google Play Edition (GPE) with CID of GOOGL001 and MID of 0P6B17000.
Proper firmwares for your AT&T CID and MID will have the number "502" in the position x.xx.502.x

That's right. And as I already stated, sunshine requires a working OS, which you don't have. And since getting the OS working again seems to be the main reason you want to get s-off, you see its quite pointless.

No problem And to flash this firmware i can do it like this:
f you are S-ON ---> Re-lock your bootloader (this will most probably wipe content of your device)
If you are S-OFF ---> no need to re-lock the bootloader.
Copy downloaded .zip to fastboot.exe location (e.g. c:/SDK/platform-tools/fastboot.exe)
Re-name .zip file to firmware.zip
Open command prompt
Boot your device in fastboot mode (vol down + power ===> fastboot)
Connect device to the PC
In command prompt cd to fastboot.exe location
Make sure you have correct modeid and cidnum (type: fastboot getvar all)
Type: fastboot oem lock (if your device is not relocked yet or in case it's S-ON)
Type: fastboot oem rebootRUU and wait for device to reboot
Type: fastboot flash zip firmware.zip and wait for process to complete
Sometimes flashing for the first time doesn't work, so flash firmware.zip again just to make sure.
Type: fastboot flash zip firmware.zip and wait for process to complete
Type: fastboot reboot
Unlock your bootloader and flash custom recovery if you are going to use custom ROM.

Those might be unsigned firmwares, but I thought they were signed.
I think your options at this point:
1) Find signed firmwares of the versions I recommended.
2) Unlock the bootloader again, flash TWRP again, then flash a 3.xx based custom or stock ROM (which will have working WiFi). Then s-off by sunshine so you can fix the firmware (will allow an unsigned firmware to be flashed).
Another thing to note, when you flashed the GPE firmware, it reverted the recovery back to stock recovery. Which is why you no longer have custom recovery.

Running android 4.4.3 with root; how to upgrade to latest Marshmallow and retain root

As per the headline, I've got an HTC M8 that I rooted shortly after purchasing in 2014. When the Lollipop OTA upgrades came out, I was reading mixed reviews about battery life and system performance, so I used a quarantine app to freeze the auto-update app so that it would stop bothering me to upgrade all the time. Now that Marshmallow has been out for a few months, the reviews seem positive and say that battery life is improved and the device is just as responsive as it used to be, so now I want to upgrade my device to Marshmallow.
I'm more or less an android / phone newbie - I mainly just use my phone for email, web browsing, driving directions, taking photos and the occasional app like banking, I'm not into heavy customisation but would like to retain root for the ability to uninstall shovel-ware, freeze programs and so some minor customizations.
Anyway, since I have 4.4.3 Android rooted, which process should I follow to get Marshmallow rooted, while retaining all the current data on my phone (apps, phone contacts, etc)? Do I need to do an OTA upgrade to Lollipop, and from there do an upgrade to Marshmallow?
My phone is an unlocked HTC M8; it's not a GPE or other branded vendor phone. I live in New Zealand and I bought it parallel imported, I think it was originally from Hong Kong.
I already have some of the bootloader/recovery stuff sorted out from when I rooted it the first time. Going into bootloader this is what prints out for me:

Please upgrade your firmware first through RUU to flash other ROMs.
[Edited]

Would this be the same as stock OTA?
Also wouldn't flashing a ROM destroy all my apps and data?

No the ROM won't be same as stock OTA,there are more or less modification in every ROM.The way you can exactly stock update by flashing RUU.
And yes all your apps and data will be wiped.Why don't you try titanium backup?you can backup all apps and app data with it.

Upgrade TWRP to the latest version.
Flash any MM ROM with S-On support.Though most of the ROMs doesn't require S-On,but but read and read about the ROM before you flash it.
Edit:You can try ViperOne ROM for the first time,i find it more stable.

MM ROMs won't work properly with his old firmware. He will lose wifi, among other issues he will face. Updating his firmware is a MUST before he flashes a Marshmallow ROM

Sorry for the wrong infos.
I flashed other mm ROMs over lollipop firmware everything's working fine.
But just got to know about firmware upgrade myself an hour ago.
Sorry again.

Lanthanide said:
As per the headline, I've got an HTC M8 that I rooted shortly after purchasing in 2014. When the Lollipop OTA upgrades came out, I was reading mixed reviews about battery life and system performance, so I used a quarantine app to freeze the auto-update app so that it would stop bothering me to upgrade all the time. Now that Marshmallow has been out for a few months, the reviews seem positive and say that battery life is improved and the device is just as responsive as it used to be, so now I want to upgrade my device to Marshmallow.
I'm more or less an android / phone newbie - I mainly just use my phone for email, web browsing, driving directions, taking photos and the occasional app like banking, I'm not into heavy customisation but would like to retain root for the ability to uninstall shovel-ware, freeze programs and so some minor customizations.
Anyway, since I have 4.4.3 Android rooted, which process should I follow to get Marshmallow rooted, while retaining all the current data on my phone (apps, phone contacts, etc)? Do I need to do an OTA upgrade to Lollipop, and from there do an upgrade to Marshmallow?
My phone is an unlocked HTC M8; it's not a GPE or other branded vendor phone. I live in New Zealand and I bought it parallel imported, I think it was originally from Hong Kong.
I already have some of the bootloader/recovery stuff sorted out from when I rooted it the first time. Going into bootloader this is what prints out for me:
If I select recovery, then I get a recovery menu, and the version at the top is: Team Win Recovery Project v2.7.0.2

First off, you need to update your recovery. Go with TWRP 2.8.7.0 or higher.
Secondly, you can update and keep all of your data. Make a nandroid backup with your new recovery, then run the appropriate RUU to update, or go back to complete stock and take the OTAs that will get downloaded to your phone, then restore your nandroid. The new firmware won't get overwritten by restoring your backup. That partition isn't included in the backups.
Hook up your phone to your PC, get into fastboot, and enter the command fastboot getvar all. Post the results here (minus your IMEI & serial# ~ that's private info) and I or someone else here will direct you on the easiest way for you to update.

No, a nandroid is a backup that is made by recovery (TWRP). It can back up the stock ROM, and user data (which is the goal in the above posted suggestion). After you update, you can restore the user data (but you don't want to restore the old ROM, since the goal is to get to MM - that part wasn't clear in the previous post).

Since you rooted, you can't simply unfreeze the updater and OTA.
OTA requires restoring the stock ROM (never rooted, unrooting does not work) and stock recovery (you have TWRP now, which is a custom recovery). RUU is an easy way to restore the whole phone to stock condition.

Ok, so if I'm understanding this correctly:
* To use the OTA updates, I need to have a stock ROM, as well as a stock recovery (not TWRP)
* I can make a nandroid backup of user data in TWRP, and then use RUU to go back to a completely stock phone
* From there I can do OTA upgrades to get up to MM
* Then I can install the TWRP recovery and restore my user data
Another approach might be:
* Backup the user data using TWRP
* Use an appropriate RUU, or series of RUU's, to upgrade to MM, without using any OTA updates at all
* Restore user data
It seems like path 2 would be easier and less risky of making a mistake. So what RUU's do I need? The output of "getvar all" is available a few posts up.
Also is there an easy guide somewhere for how to upgrade to a newer version of TWRP?

Yes, path 2 (RUU) would be easier in your case. But unfortunately, I don't think you version has RUU. You'd be looking for an RUU for 6.12.709.4
That being the case, you need to resort to path 1 (return to stock and OTA updates).

Fastboot install method is simple and reliable. Instructions and TWRP files here: https://twrp.me/devices/htconem8gsm.html
Since you already have fastboot working, just put the TWRP .img file in the same folder as wherever fastboot.exe is located, then connect the phone, and run the command:
fastboot flash recovery twrp.img

Right, I've just sat down to try and do this, and realised that I'm still not clear on what I actually need to do.
It seems there is no RUU for my phone for MM, which would be RUU for 6.12.709.4.
So instead I need any RUU that suits my phone for Kitkat or Lollipop, and then do OTA upgrades from there? So what RUU versions should I be looking for, since 6.12.709.4 does not exist?

There is no RUU for your device version. You can only restore to stock ROM and do OTAs up to the latest.
Your main mistake (I remember you have the same problem before) is restore your backup data after OTA done. Restoring old data that removed your apps like calculator & flashlight.
What you need to do (correctly):
1. Don't use that TWRP 2.7.0.2 .. install 2.8.10 or 2.8.3.0
2. Make a TWRP backup of your current data/system/boot
3. Restore non-rooted backup 2.22.709.3 (boot and system only - use your current data)
4. Install 2.22.709.3 stock recovery
5. Do multiple OTAs up to the latest 6.20.709.2
You'll upgrade your ROM and firmware but still have all your data intact.
All files needed are here : http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
If you happen to wipe all data & system before restore 2.22.709.3 (as per step 3), you can restore data only from your own backup before step 4 ... remember to restore your own data before OTA, not after OTA (if not you'll have your old problem again)

That's not RUU ... it's a ROM flashable zip. Maybe you better remove the link so it won't confused others.

HTC One M8 Bricked? Looking for help desperately!

Hello,
I got an OTA update for my HTC one but i wasnt able to install it normally. so i went into TWRP recovery and FULLY-wiped my phone(system,data,cache,dalvik). When i proceeded to install the zip, i got an error saying:
file_getprop: failed to stat "/system/build.prop": No such file or directory.
E:Error executing updater binary in zip '...'
I got the same error when i tried flashing another ROM, dirty unicorns. I tried restarting my phone and installing again WITHOUT wiping anything and still nothing. When i connect the phone to my laptop, it shows the phone as a CD DRIVE. Can someone PLEASE help me?

OTA updates usually cannot be updated via Custom recoveries like CWM or TWRP. I suggest you do roll back to a stock rom using TWRP backups found in the forums, flash a recent version of TWRP and then try flashing custom roms.
Suggesting that you start with updating your current TWRP to 3.0.2

from that i see you can access fastboot
well there is no RUU for your device but there is stock firmware,stock backup and stock recovery
you need to flash the firmware then flash twrp recovery then restore the backup and flash the stock recovery
by doing that you will be completely stock

You can't flash that RUU. Its not for your version, its for the US Unlocked or Developer's Edition, and that specific carrier ID (CID) and Model ID (MID) only. You don't have the right CID and MID to flash that RUU.
There seems to be a notion that the particular RUU is for any unlocked M8; and that notion is completely incorrect.

As would be expected, that is the stock recovery, which is a part of the stock/signed firmware; and therefore was installed when you flashed the stock firmware. You need to unlock the bootloader, and put TWRP back on the phone, if TWRP is what you want.

This is normal, and expected. Unlock the bootloader again, either with the existing bin code, or go through the HTCDev.com process again, to get a new bin code.
You can't flash a custom recovery such as TWRP (or any other unsigned file) to recovery partition, with a locked bootloader. That is what it means to have a locked bootloader; and specifically what an unlocked bootloader allows you to do.

Do not make up fastboot commands.Its simply a horrible idea. Unless you know exactly what you are doing you should only type in fastboot commands exactly as directed. You probably can't do any permanent damage with s-on, but you certainly can mess things up pretty well with the wrong fastboot commands.
For instance, what partition would TWRP be installing to, if you don't specify? Yeah, I don't know either. And that isn't a good thing.
Additionally, you don't seem to know what the TWRP backup file is. Its not a flashable zip. You shouldn't be flashing things, without bothering to read the instructions, and understand what they even are.

My advice, is to learn by reading and understanding the guides and threads on this forum.
Do not learn by trial and error, unless you want to end up making your phone into an expensive paperweight. Don't experiment, don't make things up.
I recommend anyone wanting to mod these phones, to spend a minimum few hours reading and understanding the basic concepts, guides, etc. before doing anything. And if there is anything you don't fully understand, just come and ask, as there are plenty of folks here willing and able to help.

If you don't have it on your computer (and know where it is) then it can't be "retrieved".
Just go to HTCDev.com, and follow the instructions there to unlock the bootloader.
