[Q] I have a problem.

So I have a problem. I rooted and unlocked my bootloader just fine on my T-Mobile HTC One M8. While installing insert coin to prep for s-off, I was wiping my data and accidentally deleted my operating system (oops). So I followed a tutorial and tried using firewater and I got the "whelp, no amount of retrying will make this work on your device" message. I want to use Sunshine now, but I can't because sunshine only works with stock sense, which I accidentally deleted. I have looked and looked online and the only presumable way of getting the operating system back is through an RUU which I can't do because I'm not S-Off. I can't get S-Off because I don't have sense, and I can't get sense because I'm not S-Off. Is there just a regular ROM I could use to flash sense just temporarily while I get sunshine? My whole goal of this was to make my regular M8 a google play edition, as I prefer stock android.

Who says you need to be S-OFF to run a RUU If there is an RUU available for your device then run it. Just make sure you lock the bootloader before you do.
You could also just flash a ROM(any rom) onto your device or restore a backup from the collection of stock backups thread(In general section).

Also I tried downloading a stock sense rom and when I flashed it, my phone turned on and the message "unfortunately, phone has stopped" just kept coming up over and over. Do I need to find a Rom specific to T-mobile and/or my device version?
Thank you so much for your quick response and help!

To lock bootloader, shut down device. Hold Power button + Volume down to boot into bootloader. Connect Phone to PC. Open command prompt in adb folder. Type
Code:
fastboot devices
To check if the device gets picked up, Next type:
Code:
fastboot oem lock
This will lock bootloader. Then you can run the RUU.exe as administrator on your PC and begin restoring your device back to stock.
Why do you need to lock it? I'm not entirely sure Perhaps it's just part of the verification the RUU needs in order to make changes to the device, kinda like you need to be stock to do OTA. Maybe it just has something to do with the oem method of recovering/restoring the device, I don't know mate, sorry.
Perhaps someone with a bit more expertise can answer that one for you, I only know that it needs to be locked if you're S-ON.

You'll need to be S-OFF in order to convert to the GPE as it makes changes to the partition sizes on the device. If I recall correctly it was Graffixnyc that made a thread about that and I'm almost sure he mentioned in that very thread that you need to be S-OFF.
First restore your phone to working condition, then get S-OFF then you can follow the guide to convert your device to GPE.

Just make sure you download the correct version that corresponds to the version your device is.
If you need earlier or other version it's in here: [Recovery] [RUU 2.22.531.5] [TWRP Nandroid Backups] [Radio IMGs][ OTA 2.22.531.6]
Once that is done you can just right click on the exe file, select run as administrator and follow the onscreen wizard to restore the device back to stock.

Hey there!
So I restored my phone and it worked, so I s-offed my phone using Sunshine (because like I said before firewater didn't work for me), and I downloaded the GPE RUU but for some reason when I type adb reboot bootloader into cmd it says error:device not found. When I plug my phone in, it makes the noise that signals that a device has been plugged in, but it doesn't show it in the file explorer. Any ideas?

Nevermind, realized I didn't have USB Debugging on.

[SOLVED] T-Mobile M8 Stuck In Recovery With ReLocked Bootloader and No ROM!

The title basically says it all but I'll describe what I did so hopefully you guys can help.
Today I got tired of the ROM I was running and I figured I'd update my firmware before I flashed a new one just cause I hadn't done it in months. So I went and followed this guide: http://forum.xda-developers.com/showthread.php?t=2696282
I used this firmware: https://www.androidfilehost.com/?w=files&flid=32788
My CID is T-MOB010 just like the firmware's and I thought it would be a pretty simple thing, so I got to work.
First I rebooted to fastboot USB and did fastboot getvar all to make sure everything lined up, then I relocked the bootloader and did fastboot oem rebootRUU, all successfully.
Then I flashed the firmware and it all went great but I forgot to flash it a second time. I'm not sure if it's required, but anyway...
After it flashed successfully I did a fastboot reboot and my phone tried to reboot but it stalled on the white HTC splash screen, then went black, then the splash screen returned, then black, then it went into the stock recovery.
The stock recovery functions just fine and I attempted to just clear the cache and reboot but it did the exact same thing.
I don't currently have a stock Nandroid or RUU on my phone and I'm not even sure I have a way to get one on there besides using someone else's phone to put one on my SD.
Can anyone help me out? Is it even possible to get out of this? My bootloader is relocked and my phone can't get S-OFF (tried awhile ago multiple times). As of now I am all out of ideas/experience so I'm hoping you guys can help me. Thank you!!
UPDATE: I got myself into the HBOOT so I think I should be good now but I'll keep this around just in case.
Update: Once I got into hboot all was well, I just flashed TWRP again and got it going. Thanks everyone for the help!

Did you get it going again?

Just use the official RUU.exe which runs from a PC (with phone connected), not from the phone.
http://www.htc.com/us/support/htc-one-m8-t-mobile/news/
RUU will also update your firmware.
Also, the firmware you linked is not the latest. Its the Android 4.4.4 firmware. The 5.0 (Lollipop) firmware would be 4.20.531.4

Its not what your top post says, so its not clear whether you were trying to put the RUU.exe on the phone (which is incorrect), unsuccessful in putting on the phone or running an RUU.zip, or did the latter in addition to trying to run the RUU.exe from the PC (which was not originally mentioned). If the last one didn't work, it would help to have more details on failure mode, error messages, etc.

Not everyone does it, but its certainly good to do, and still done from time to time. Its helpful so folks don't click on a link, intending to help someone that doesn't need the help anymore.

Same kinda problem.
I'm stuck in bootloader.
Any key I just brings me back to this again.
Even in HBOOT selecting Recovery or Factory reset does nothing other than bring up this screen.
Powering down and then on again has the same result.
I was trying to get back to stock. Typed in fastboot oem lock and after that... the problem started!!
Any ideas??

This is intentional. When you relock the bootloader, it renders the phone unbootable and expects the RUU to be run.

Ok. I'd downloaded what I assume is the correct RUU.exe. Ran it from the computer and I get a 131 error. Not the correct RUU !!

You shouldn't be assuming what RUU to run. What is your CID and hboot number? What RUU did you try to run?

HBOOT is 3.19.0.0000 CID, can't find.
RUU is M8_4.16.401.10_Europe.exe

The OS number (3.32.206.9) shown on your hboot screen (pic in your top post) indicates that is not the right RUU. The number in the x.xx.206.x is carrier specific,and seems to indicate that your phone is the O2 UK version. Running an RUU with version x.xx.401.x won't work. The number in the "401" spot would need to "206" for it to be the right RUU.
Not sure, but I don't think your CID has RUUs. If that is the case, your best bet it to unlock the bootloader again, flash TWRP back to the phone, and restore a nandroid with your software number (3.32.206.9) if you can find it. Then flash stock recovery back to the phone. That is as close to "stock" as you will get, if there is no RUU for your CID version.

Thanks redpoint73. Looks like that's the only way to go!!

By looking at the radio, you need the Euro Version RUU. Looks like we gotta be detectives sometimes, lol.

Ok, I've unlocked the bootloader and am back to where it was.
It's running 5.0.1, Sense 6.0 and Android Revolution HD 34.6 by mike1986
I would like to clear that off and get back to stock with OTT updates.
Revolution HD 34.6 seems to use an awful lot of data. My other M8 has stock on-board, has identical apps etc and doesn't use nearly as much data as this one!!
Any further ideas??

I'm downloading that now. BUT...........
Because of all my faffing on!! there's NO OS on the phone.
I'm really struggling now:crying:

This is my position now. Totally unusable phone!!
I would appreciate ANY help on getting back to as near as normal as possible.
Thank you.
I should add, the RUU messages are from trying post #16.

And the saga continues!
I found a nandroid backup with the same s/w number as mine, downloaded it from MEGA (it seemed to d/l ok).
When I ran it through TWRP I got signature verification failed.
This phone could end up in the depths of the river Tyne

What hack14u neglected to mention, is that to run another version's RUU, you need s-off ($25 by sunshine), and then you need to change your MID and CID.
Relocking the bootloader (to run RUU) renders the phone with no OS, this is by design.

Hang in there, modding phones can often be an exercise in frustration. But the phone is quite recoverable, as long as you perform the correct steps.
A nandroid is not a flashable zip (such as a ROM). It needs to be restored in a very different way, its described in Post 3 of the stock nandroid thread (assuming that is where you go it from) under Question & Answers.
To summarize, you need to:
1) Unpack the zipk, which is a number of folders
2) Move the folders to the proper location on the phone's internal storage (removable SD is also possible, if you setup TWRP to back and restore to that location)
The exact location if very important (its described in Post 3 of the stock nandroid thread), since when restoring a nandroid, TWRP will not see the file to restore if you have it wrong. This is in direct contrast to installing a ROM zip, in which TWRP allows you to browse anywhere on the storage to find the file to flash.
3) Choose the menu option to RESTORE, not INSTALL

How to install a MM Custom ROM while on KITKAT? (International version)

Day 1, I got my phone I unlocked bootloader and rooted.
I created a backup and tried installing Android Revolution HD 53.1 and it worked, however my WiFi didn't work and boot times would be long, so I uninstalled it and went back to my backup I had made. I read that this happens because my current firmware 1.58.502.1 (4.4.2 KITKAT) is too low (incompatible) to download Android Revolution HD 53.1.
Recently I also bought the sunshine S-off method. So I am currently S-OFF.
ALSO worth noting while I have the international edition of HTC ON M8, I am using T-MOBILE
With S-OFF am I able to go directly to Android Revolution HD 53.1 (which is MM Custom Rom)? If not how do I make my devie compatible with this version?
I would appreciate any help, thank you.

Please do, I'll be more than happy to help with any questions although you seem to have 90% of this down. The other 10% is small stuff only plausible via sunshine.

Lollipop 502 (AT&T) firmware can be found here (packed with custom ROM): http://forum.xda-developers.com/att-htc-one-m8/development/att-4-4-3-2-22-1540-3-debloated-sense-6-t2837365
Another option (since you have s-off) is to change to Developer's Edition CID or SuperCID. then flash to Marshmallow firmware or MM RUU (if you want to be all fancy like that). Although the current custom ROMs (including MM ones) should run fine with LP firmware (its KK firmware that is the main problem).

Honestly, I gave up. I was reading some tutorials but did not understand what I had to do. I come from a Galaxy S4 and that phone is infinitely more times easier to mod than this phone. I have had to jump through so many hoops to just root it.
However, I have no idea where to go now, I feel like such a noob.

Woo did a quick check at work to see if my device was compatible. My CID is CW__001 so looks like it will be compatible, can't wait to get home and try it hopefully I don't brick my phone! Will keep you updated, thank you.

Stick with it. Every device has its own learning curve. And we're happy to help and explain as much as needed to get the job done.
But really, flashing the firmware is not too difficult; especially considering you've already accomplished unlocking the bootloader, know how to flash custom ROMs, etc.
The link I gave you has instructions on how to flash the firmware. After doing those steps (1-3) just flash TWRP 3.0.0.0, as the version indicated in the page I linked is a bit old.

UPDATE 2: Got past the boot, now waiting on "Android is upgrading... Optimizing app 44 of 223" (damn bloatware!)

HTC ONE M8 security warning in FASTBOOT mode

Hi every one I have htc one m8 now 2-3 years, I rooted and unlocked bootloader, on stock firmware which is : 4.18.708.12 and now I have system updates that I cant update cuz im rooted , so I relocked bootloader and tried to update , still when i try it goes to fastboot with this : system software modified, security warning and it doesnt update nor perform a factory reset, can some one help me out here? id be glad I need this help asap

You need stock ROM, and stock recovery to update by OTA.
Return to stock ROM and stock recovery using this thread (which will then allow you to update): http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Relocking the bootloader isn't necessary to OTA (only to RUU or flash signed firmware.zip) and didn't help you matters. You'll need to unlock it again in order to perform the process linked above.
Factory reset also won't help your condition, so there isn't a point in doing so. Factory reset is a bit of a misnomer, all it does is wipe user data. It won't restore a previous OS, nor remove root, etc.

If that is what you wanted, then no mention was made of that in your OP (which you should have done). You should be specific about what you want, and not make it harder for folks trying to help you.
You are incorrect (that after installing the stock ROM, you will still be rooted). Installing the stock ROM will remove root. That's the whole point of the thread I linked.
If there is an RUU for your version number, just use it to return to almost full stock. When I say "almost", its because the bootloader will only say RELOCKED instead of LOCKED. The only way to make it say LOCKED (after its been unlocked) is with s-off. And if you don't already have s-off, it will cost you $25 by sunshine. Probably not worth the cost, as you no longer have warranty, anyway. HTC warranty is only valid for 1 year.

and how do i decide which RUU is suitable for my device?
android 5.0.1
software number : 4.18.708.12
I must point out that I never installed a custom rom nor recovery I just unlocked bootloader and rooted and thats it so how do I find my ruu and what to do if i dont?

Its not actually clear what you are trying to do. Return to stock to update? Or something else? Your later post says return to stock for warranty, but no way you have warranty at this point. Is something wrong with the phone? Or just trying to return the phone to stock to sell or trade it?
Can't really provide proper guidance unless we know your intent.

You look for an RUU for that version number you just posted.
If no RUU, the process I linked for you in the first place will return you to full stock, with the exception of bootloader will be UNLOCKED. Or you can make it RELOCKED. Not really much different from what an RUU would give you.

I didnt mean to get my warrenty back, I meant to get back to stock just like when getting back to original phone status like it came from the company, so I understood that flashing stock rom and recovery will help me with geting back and stat updating normally, but the precess seems too complicated to understand I might need your further help perferably vie Direct message, but just to save all the efforts, Id perfer the RUU flashing, and since you said none original RUU that has the same number of my version , that means I can install any one I want? whats the difference between RUUs and how do I choose the perfect one

I strongly suggest you take a bit more time thinking about what you post, and making sure its properly typed, (lack of proper capitalization, spelling and punctuation makes your posts a pain to read, to say the least) and conveys what you want it to. Otherwise, you're just making it harder for folks to understand and help you.
Any time you think you are saving by typing quickly, is being lost x10 by me having to ask you to clarify what you mean.

The process isn't complicated. If you managed to unlock the bootloader and root the phone, you can certainly accomplish restoring the stock ROM and stock recovery. On that same note, it can be fairly said that anyone that is unable restore the phone by that method; probably shouldn't have unlocked the bootloader and rooted to begin with. Or look at it a slightly different way: you should never root a device without knowing how to return it to stock.
The guide looks long, mostly because its written in a very highly detailed, step-by-step manner (some folks seem to like that). But it just boils down to downloading the proper file, unzipping the folders, putting them in the right location on the phone, and restoring in TWRP.
If you have issues on a particular step, feel free to post again here, or the TWRP stock backup thread we are discussing.

I never said there was no RUU for your version number; or did you determine that yourself (your wording isn't clear)? I don't definitely know if there is or not; I was leaving it up to you to search. But doing a quick search myseld, it looks like NO.
If you looked, and there is no RUU for your version, you certainly cannot run any RUU you like. In fact, you can't run any RUU at all, unless its intended for your version, CID, MID.

Why did you flash signed firmware? Its not a ROM, not an RUU. Nobody told you to do this.

How did you flash the firmware? By fastboot, or SD card method?
What's the exact file name for what you flashed?
Any error messages?
Did it tell you to flash again (very common, but actually says "flush image immediately"), and if so, did you flash it again?
Try holding power button and vol up for a minute or more, and see if there is any change.

You have to get the phone back on, in one mode or another, before you can do anything.
No, you can't flash the stock TWRP backup with adb. Its a TWRP backup, and you have to restore it with TWRP.
You can't flash custom recovery with the bootloader locked. That is why you have signature verification error. You need to unlock the bootloader again, which I already told you. And you need to be in bootloader-fastboot mode to flash it, anyway. I thought you said the screen wasn't coming on?

but now there are no software updates available
PS: I did exactly what the post said! now i am back to stock rom with stock recovery and when i go to check updates it says my device is up to date (on lolipop 5.0.1) but before I had 6.0.1 marshmallow available now its not.

Google play issue

I bought a used M8 At&t I don't have yet. But the seller says the following about the phone. Google Play crashes during setup, preventing setup from completing. The phone looks great. Is this an easy fix?

Sounds like a software problem, this can be easy to fix with a ruu.

Can you please recommend what I would need for att variant? Should I just get the latest nougat? This ruu correct 6.20.502.5is? Just htc rom update that's it? In fastboot?

There is no official (HTC) Nougat software/firmware for this device. They stopped at Marshmallow, which 6.20.502.5 is.
RUU is a full stock/factory image. It will wipe all data on the phone (probably not a bad thing in your case) as well as re-write all partitions to "stock" condition. If your problem is with software (and I'm thinking it probably is), the RUU will likely fix it.
I assume you have the .exe format RUU (which is the most likely case). In which case, connect the phone to PC. Run the RUU, and it's pretty self-explanatory from there. Having the hone booted to OS should be okay, but bootloader-fastboot mode is even better.

The RUU may or may not work, depending on the phone's current condition. Which is why lucyr03 asked for the getvar data, so we can give you more specific advice.
