Yeah, I certainly learned that the hard way. :(

Yes unfortunately I did. No TWRP back ups exsist.

I attemped to flash the rom 155.502.18 via a zip file to the phone. Nothing. I attempted loading up a boot.img from some YouTube view I watched that I can't link because I don't have 10 posts on here yet.

I'm sorry, I don't know what a command syntax is. I got the file right off here in XDA Forums in the ROM's folder for AT&T stock rom. The error just says "failed" and will not write. It seems to keep missing an "MD5" file. The error in CMD prompt is that it just doesn't go anywhere after I type in >Flashboot Flash Boot boot.img

I did not know that. I was just trying to figure out how to get this to work again. Yes, I did delete the system partition, so I guess I will have to restore an entire ROM (1gb of space for a Sense ROM). The problem is, I don't know which files from these .zip files on XDA are the correct files, and I can't seem to find any videos on YouTube that show the problems I'm having.

I apologize for the lack of information. I have some screenshots of the errors and what the TWRP recovery bootloader looks like, but I can't attach my image files to this post because It says I need 10 more posts. Otherwise I would have tried to post more information. "he said". I am a woman*. I did try a fastboot getvar all before, so I'm aware what that is, but I'll have to post short messages around here to reach my 10 post mark so i can start including some screenshot images.

Relative question. What is the difference between manually flashing a ROM through the CMD prompt on my comptuper vs "RUU". I don't have any current operating system on the phone so I can no longer go into the settings and turn off USB debugging and whatever else I've seen instructions on using RUUs. Which all seem to indicate I need an OS before even doing that option.

THAT IS THE GOAL! I would be SOoooooooooooooooooooooooo happy if and when that can finally happen. Annnnnd I"ll never be buying anymore phones that are rooted again, because I don't want to go through this annoying process of unrooting. Now I know why the seller didn't unroot!, lolAnd THANK YOU to all for your replies. I shall post more information
[One (M8) Q&A, Help & Troubleshooting] cami0488:
I got this .zip file from the XDA ROMs folder off here. I'm not sure if it's an RUU file. However it is not a backup, or so it wasn't labled that way. It was labled as the "stock ROM"
[One (M8) Q&A, Help & Troubleshooting] hack14u:
Try what I said. Before, run the command fastboot OEM lock. That will relock the bootloader so you don't throw an error when you run the RUU. The RUU will wipe everything and bring it back to ATT stock. From there you can learn more commands, and how to "fix" things. An RUU is the stock files packaged as a .exe file, you actually run it from your PC like you were installing a piece of software, but it goes to your phone. Don't worry about not having this, or that, it will fix it for you, unless something else is not set right. Give it a shot, you have nothing to lose, literally. :) Oh, and I always run RUU's from fastboot USB so it detects it pretty quick.
[One (M8) Q&A, Help & Troubleshooting] cami0488:
See, I read about using RUU, but I also read that if you have "S-on" you can't flash anything on the device unless you do it through the cmd prompt. That's what caused my problems to begin with, I didn't know where to start after having accidentally wiped my OS, backups, and damn near everything. So it can still work via the RUU method with my S-On? I shall try it tomorrow after work.

Thank you for your response. It is much appreciated. However there is no need for the reprimand. What has happen has happen, and I have already decided that I will never again buy a rooted phone with the intention of unrooting it myself. What worked for me on my Xperia Z2, Galaxy Note 2, Galaxy S2, and HTC Evo is obviously nothing similar to what is going on here with the HTC M8. Therefore I will avoid a situation like this entirely by never attempting to unroot phones again. (I'm not personally a fan of flashing ROMs anyways)

Anyways, I'm going to try locking the bootloader as you instructed now, and then downloading the RUU file from HTC. Thanks again. I'll keep this updated.

[One (M8) Q&A, Help & Troubleshooting] cami0488:
Just relocked the bootloader as you instructed

Downloading the RUU that RedPoint73 provided in his last post. Once that is downloaded, All I have to do is run the .exe program like normal and it should prompt me to a location where I can flash the information to the phone?
[One (M8) Q&A, Help & Troubleshooting] cami0488:
While i'm sitting here waiting for the RUU to download. I had yet another question. The rooted ROM that the phone was originally flashed with was Android High Definition Mike1986. For whatever reason, it would not ever let us connect to Google Play. Anytime we reboot, hard reset, factory data reset, or format the whole thing back to default settings we would always get the same message "google play services are not available". Now that was a problem of the ROM I stated, but is that related to the ROM that is flashed, or the phone itself?
[One (M8) Q&A, Help & Troubleshooting] cami0488:
Ugh oh. So I decided to run the RUU. The phone looked like what seemed to be installing. But the installation estimates it take 10 mins. I's been 20 minutes and is still 0/6 completed. I think something is wrong.
[One (M8) Q&A, Help & Troubleshooting] hack14u:
It probably didn't have any gapps package installed.

It looks like it connected, let us know if it worked, like I said before, if it doesn't, there is something else wrong.

I don't think I have ever seen any of that after fastboot oem lock. Has anyone else seen anything like that? Something looks very strange, like all of it.

Oh ya, ARHD is the ROM you are referring to, some of the best folks out there, great work.
[One (M8) Q&A, Help & Troubleshooting] cami0488:
I found this site - http://www.droidviews.com/restore-att-htc-one-m8-stock-firmware/ that seems to also to have directions to do the exact thing i"m doing now. But the very first part of the instruction yet again says "S-OFF is REQUIRED. It connected, and found the phone, but it stays stuck on that screen right there. I have tried retrying this 3 times. Waiting 20 mins a piece with no progress.
[One (M8) Q&A, Help & Troubleshooting] cami0488:
I have the the phone saying RELOCKED near the top of the screen. When I try to run RUU it does not want to install anything. Yet http://www.droidviews.com/restore-att-htc-one-m8-stock-firmware/ claims I DO need to have S-off to get it to work.
[One (M8) Q&A, Help & Troubleshooting] hack14u:
S-Off would be required to return to stock if you had converted to GPE, or Dev Edition as most of us in here have done at one time or another. Me personally, I prefer Dev Edition, but to go back to stock ATT, it has to be S-Off. I think that is what the author was getting at, but didn't put it in his article.

---------- Post added at 07:40 PM ---------- Previous post was at 07:38 PM ----------

Before you run the RUU, make sure that you can already communicate with your phone. If you can't then the RUU can't either. I always run RUU's when the phone is in fastboot USB mode. When all goes well, you will see HTC in the middle of the screen with a green progress bar at the bottom, then it's writing everything.
[One (M8) Q&A, Help & Troubleshooting] cami0488:

And nothing happens with the RUU? Hmmm, I haven't tried the Lollipop RUU, I wonder if something has changed since the 4.4 RUU.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
If you had to unroot all those other phones, what makes you so certain that you will never have to do so ever again ((even if you intend to "never" buy a rooted device again)?

You should strive to learn from your mistakes, and understand why things happened as they did. That's the point of my explanation (call it a reprimand if you will, but my comments are obviously not without basis).

---------- Post added at 09:01 PM ---------- Previous post was at 08:58 PM ----------

Probably an issue with the ROM.

---------- Post added at 09:02 PM ---------- Previous post was at 09:01 PM ----------

You don't need to install gapps on Sense ROMs. Probably just an isolated bug on that ROM, version, etc.
[One (M8) Q&A, Help & Troubleshooting] hack14u:
Ya, I just checked his page, my bad. Sometimes I forget, Sense, GPE, sense, etc...
[One (M8) Q&A, Help & Troubleshooting] cami0488:
I certainly am learning from my mistake. The mistake of buying a rooted phone thinking it would be as easy to unroot it as I did those other phones. This is a hard lesson learned. Of course I'll never be in this situation again, I've learned it's most worth my time to avoid it. I personally found no benefit to rooting and flashing ROMs and I've been on Android since Froyo. I don't begrudge people who have fun doing it, but it's certainly no fun for me. Still can't figure this out. At this point I think I might put it right back up on eBay and get an unrooted stock one. Been battling with this for weeks now and I really need to use the phone. I've wasted so much time an effort on this thing already.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
S-off on that webpage is so that you can change the bootloader from RELOCKED to LOCKED, which is only possible with s-off. With s-on, it will only every say RELOCKED or UNLOCKED once its been bootloader unlocked.

The only purpose for making it say LOCKED is for warranty purposes (so HTC can't tell its been tampered, modded, etc).

S-off is

not

needed to run the RUU (as long as you relocked the bootloader and run the right RUU version). I am 110% sure of this, and you can stop worrying if that is an issue. RUU is an official recovery tool provided by HTC for stock (s-on) devices, and you will find it on HTC's support page (as hack14u linked long ago on this thread).
[One (M8) Q&A, Help & Troubleshooting] cami0488:
I am searching for older RUU's for this phone. Maybe something just does'nt want to work correctly to the one you linked me.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Nothing has changed as far as running an RUU (LP). I've seen this before from a few users, but its a tough one to solve (not even sure I've seen a definitive cause or solution for it). RUU is losing its connection, even though it seems to have (at least a fleeting or initial) fastboot connection.

cami0488, what Windows build (7, 8, 8.1,10, etc.)?

Do you have USB 3.0 on your PC's ports?
[One (M8) Q&A, Help & Troubleshooting] hack14u:
Ya, I had nightmares on Win 8 and 8.1 until the update came out. I have noticed glitchy USB cables even can cause this. I just ran some commands on Win 10 and it's all good there, first time I tried on 10.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
That's certainly a possibility (that something unique to your situation is stopping the LP RUU, I know for fact its worked for others), and not a bad idea.

Search no more, the other ATT RUUs are linked on my Index thread: http://xdaforums.com/showthread.php?t=2751432

You can typically only run the same or higher version number RUU with s-on (

that

is one thing that s-off gets you, the ability to "downgrade" by RUU). But since you are on the first version hboot 3.16 anyway, that means you should be able to run

any

of the ATT RUUs.
[One (M8) Q&A, Help & Troubleshooting] hack14u:
Holy cow, you actually have the link to 4.4.4, that's the magic RUU, I have never had troubles with that one. I keep that front and center.

[One (M8) Q&A, Help & Troubleshooting] cami0488:
Alright so here is the latest: I relocked the bootloader, so it could work better with RUU, and I have also verified that I have HTC Sync installed so my computers recognize the phone.

- I downloaded the 1.5gb RUU file from HTC with Lolipop 5.0. Doesn't install via fastboot on my surface pro with USB 3.0.

- Tried the RUU on my desktop that uses USB 2.0. Nothing.

- So I downloaded Kit Kat 4.4.4 RUU. And attempted to get it to work on my desktop with USB 2.0. Nothing

Both computers are Windows 10.

Does anyone have any other advise?
[One (M8) Q&A, Help & Troubleshooting] shirreer:
Ok. If you've downloaded the RUU for your phone, then we should be able to go.

1. Run the ruu, click next, and accept the terms.

2. Assuming C: is your primary Windows drive, Go to c:\users\yourusername\app data\temp\

3. Search for ROM.zip and copy it to your desktop.

4. Rename the copied ROM.zip to 0P6BIMG.zip

5. Copy 0P6BIMG.zip to the root of your SD card (not internal phone storage).

6. Turn your phone off, then hold both Vol+ and Vol- buttons then press and hold on the power button.

7. You'll be prompted to install the ROM; Confirm, then wait for completion. When its done, you'll be prompted to reboot ; Confirm.

8. Profit.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
That's probably the main problem (with RUU running). The RUU won't work on Win10. The RUUs and HTC drivers in general often have problems when a "newer" Windows build comes out (often taking several months before the kinks are worked out), and Win10 is brand spanking new. I've seen a lot of reports of RUUs failing with Win10, and not a single report of RUUs working with Win10.

You can try the method posted by shirreer, which doesn't require a PC. Otherwise you can try one of the "bootable" 1.58 or 2.23 RUUs posted in my Index thread. (also no PC required).

Another option, is try to get access to another Windows PC. Win7 is probably the most likely to run (and USB 2.0 or lower ports); although Win8.1 may be okay too. Win8 and especially Win10 are known to be problematic.

---------- Post added at 09:06 AM ---------- Previous post was at 08:57 AM ----------

Yes, USB 3.0 has caused RUU (and fastboot in general?) issues for lots of folks here.

[One (M8) Q&A, Help & Troubleshooting] cami0488:
Since neither of those worked. Can anyone recommend any other ROMs I can get on there so I can at least use the phone? It's kinda of just a paperweight at the moment :-/

I did notice that my main screen no longer says "tampered" and has an "os" listed. Could this be causing it not want to work? I"m now on day 5 with an average of 3 hours a day working on this. 15 hours. I'm starting to think it would have been cheaper to just re-buy this phone on eBay locked and stocked than waste more of my time. If no one else has any other suggestions (and I appreciated ALL OF YOUR HELP) I will be selling this phone (and will link the listing to anyone who would be interested in buying it, they know what's wrong with it) and buying non rooted phone. Is there a trading area on this forum? I would happily trade someone this phone for one that is completely back to stock. Lesson learned, never buy rooted again... :rolleyes:
[One (M8) Q&A, Help & Troubleshooting] cami0488:
Would you anyone else be willing to do these steps for me and putting the file to a google drive for me to download? I've looked everywhere for this ROM.zip. I can't find anything like this.
[One (M8) Q&A, Help & Troubleshooting] shirreer:
The ROM.zip file is extracted only when you run the ruu and proceed to installing the ROM. It'll be deleted right after the ruu exits. So, you have to get it WHILE the ruu is running! Also, make sure that you make hidden files visible for the temp folder ( from folder properties ). Moreover, the ROM.zip will be inside one of the many temp folders, so you should use the search function to find it.
[One (M8) Q&A, Help & Troubleshooting] cami0488:
Damn. I did everything you already mentioned already. I had to make the folders visible or i wouldnt have found the temp folders but no ROM temp file exsists!. And Ive tried leaving the installer at different parts. One with the installer at the part right after accepting, and another at the next screen. I have not closed the RUU in any of these attempts. But I'll try looking again... God I ****ing hate this... :crying: I'm so sorry, I have to vent. Could the reason I can't find it because I'm using Windows 10?
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
At some point after your Post #23, your hboot (which was 3.16 in that post), radio, and OS number were updated to the latest (Lollipop) ones. Presumably, the 4.28 RUU exe worked enough to change these, but not get your phone running. That is the only way I can think that the hboot, radio and OS numbers were updated to Lollipop (as evidenced by the numbers in the screenshot I quoted above from Post #42).

So unfortunately,

now

the 4.28 is the

only

RUU that will run, due to the fact that you can't run older RUUs (downgrade) with s-on.

If you had run either the 1.58 or 2.23 zip RUUs with your phone in the condition shown in Post #23 (hboot 3.16) it probably would have worked. But now its too, late, and you are very limited to the RUUs you can run.

---------- Post added at 09:11 AM ---------- Previous post was at 09:08 AM ----------

Newer or equal. The RUUs were newer, based on the information I had at the time. hboot number in Post #23 indicated she was on OS number 1.xx (probably 1.58). Meaning she could have run

any

ATT RUU. Unfortunately, she somehow got up to the most recent Lollipop hboot (3.19), radio, OS number; presumably due to the failed 4.28 RUU executable.

---------- Post added at 09:16 AM ---------- Previous post was at 09:11 AM ----------

The numbers are sequential, meaning 2.23 is newer than 1.58. This is esoteric knowledge, and you can only know this from experience. For reference, on the ATT M8:

hboot 3.16 = OS 1.58 = Android 4.4.2 Kitkat

hboot 3.17 = OS 2.23 = Android 4.4.3 Kitkat

hboot 3.19 = OS 3.42 = Android 4.4.4 Kitkat

hboot 3.19 = OS 4.28 - Android 5.0 Lollipop

Yes, hboot 3.19 is used for both OS 3.42 and 4.28, so then you have to look at OS number, radio, etc. to tell the difference.
[One (M8) Q&A, Help & Troubleshooting] cami0488:
I knew it!!! Thank you for confirming this! I knew I was doing everything correctly and had a feeling the change in those numbers had something to do with it not wanting to work! So i guess my only option now, is to try and retrieve the ROM.zip from the 4.28 RUU like you had suggested?
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Hang in there, we can do this!

---------- Post added at 09:25 AM ---------- Previous post was at 09:22 AM ----------

Surely you have a friend or family member that will let you use their Win7 PC to run the RUU exe? That's one option.

Or I can try to capture the ROM.zip and post it. But it will take a while to upload, its a huge file . . .

There another option, which is to unlock the bootloader again, and flash a custom nearly stock ROM. But that doesn't accomplish the stock, non-rooted condition you are looking for.

You guys are amazing.... I applaud the support from this forum, its wonderful.

- I would pay you for your trouble in retrieving the ROM file since I can't seem to do that... Or, donate to this website. All of you are outstanding in your tech support. I am awed.

- yes, I would be willing as well. Flashing a custom, nearly stock ROM would at least enable me to use the phone. And of course this time I'll back it up.. Would any of those custom roms be able to receive OTA updates? That was another one of the issues I didn't want to run into. This phone is for my little teenage brother who has absolutely no tech experience. I'd hate for his data to randomly just mess up because he took an OTA update and didn't realize it.
