Bootloader Unlock Question

Ok, so I have recently switched to a HTC One M8 and I am puzzled by a few things regarding unlocking the bootloader and flashing ROMs. Coming from a Samsung Galaxy s4 I have never really needed to worry about unlocking my bootloader. I have looked up on the subject and have found that with unlocking the bootloader using HTCdev you have to flash boot.img everytime after flasing a ROM on the HTC One. Does this also apply to the HTC One m8 ? If so does anybody have a better means of unlocking the bootloader without needing to do this after every ROM flash.

You don't have to replace hboot unless you want to get rid of certain firmware messages, like the tampered flag. Unless you are sending your phone in for warranty work, you won't likely care about it, since you only see it in fastboot/hboot mode. The only thing the token does, besides unlock the boot loader, is remove certain preloaded apps, like the flashlight, which will screw up further OTA updates.
However, I would suggest you look into going S-off, as it makes locking/unlocking the boot loader possible without contacting HTC at all, and without messing up OTA updates. You also gain the freedom to change your CID (if you ever want to convert to stock Developer Edition), SIM unlock, and revert to older firmware if necessary (such as restoring an older RUU to go back to stock) However, S-off is "security off", so there is an increased chance of bricking the phone if you aren't careful.

Ok so what i understand is: To install a custom rom I first have to get s-off, then unlock bootloader, root and install custom recovery and I am good to go? Please help me if I have missed anything.
I am used to flashing a rom every week on my Samsung. This is why I am so worried that I might do something wrong.
Edit: I have also found this link: http://forum.xda-developers.com/showthread.php?t=2265618 please tell me if it is the correct way to do it.

I would suggest you use this guide.
Im going to use it this friday to root my phone.

Ok so if I understand correctly now...using that guide I will not need to use htcdev and it will not be neccesary for me to flash boot.img after every rom flash?

Not quite. To flash a custom ROM, all you need to do is unlock the bootloader, install custom recovery, and flash a ROM. In addition, I highly recommend you make a nandroid backup before flashing anything
S-off is only needed if you want to avoid the bootloader unlocking method via HTCDev.com (and HTC therefore having a record of you unlocking by IMEI); or to flash hboot, radio, firmware, or a few other things (such as SIM unlock). S-off is not needed to flash a ROM.
One caveat, if your phone presently has older firmware, you will experience some severe bugs on any Sense 2.x based ROM (long boot times, broken WiFi or Bluetooth) and having S-off is required to manually update the firmware. So, while in literal terms, S-off is not needed to flash a ROM. But if the above applies to you, you need s-off to manually update the firmware and get the ROM to work correctly. Alternately, you can OTA to the latest firmware before modding the phone. You will need to list your phone's hboot and present software version for us to tell you what firmware you are on.
Also, its not necessary to root before flashing a custom ROM. You will be rooted after you flash a custom ROM.

Definitely not correct. That guide is for the M7. Be careful what device forum section you are in, and stay in the M8 section.

Hell, I feel like a noob again. Ok so no boot.img flash after flashing a rom is needed.

Nope, not needed. Boot.img will flash automatically along with the ROM. Don't assume that anything on the M7 applies to the M8. These things change as the hardware changes, and every device has its own subtle differences.

Correct, no need to flash boot.img separately when flashing ROMs, if you unlock the bootloader via HTCDev.com (or by the S-off way).

[Q] No WiFi

So long story short, I messed up and wiped my OS off my phone via TRWP. After reinstalling and looking/asking around on the forums, I managed to reinstall it, but the WiFi is no longer working. Then after some more looking/asking, I gave up and sent in to a store for repairs. It came back and the guy said he couldn't do anything to fix it.
So... now I'm here asking again. Does anyone have any idea how to fix this?
Here's an image of my bootloader
http://imgur.com/SswEXd2
As you can see, the OS- is blank. I'm not sure if that's normal or not, but I'm 99% sure that there's supposed to be some code following OS-

You likely flashed a ROM that is a different version from what you had before, and does not match your firmware (hboot, radio, WiFi, etc. - modules that do NOT get updated when you flash a ROM).
Your hboot goes with Android 4.4.3, or software number 2.x. So flash a stock or custom ROM based on software 2.x, and WiFi should work again.
You likely flashed a ROM based on Android 4.4.4 or 5.0, and therefore no WiFi.
And no OS number listed on hboot screen is a common bug found on older TWRP versions.

Which ROM do you recommend?

Most custom Sense ROMs based on software 2.xx should work.
You might also be able to use 1.xx software based ROMs, as well. Firmware is usually "backwards compatible" (with older ROMs) but never forwards compatible.
Also, next time make a backup of your stock ROM. One of the great things you can do once you have TWRP installed.

I'm looking for a 2.xx rom right now.
Also, another question, could I update the firmware without flashing the ROM first? Or do I need to do that prior to updating the firmware?
EDIT: I'm unable to find a sense 2.xx for the HTC ONE M8. Or does the phone type not matter as long as it's a sense 2.xx?

No. You want to update the firmware first. You should also update your recovery before flashing the new firmware. Then your OS won't be blank anymore (after you flash new firmware).
If you want a 2.xx based ROM,. you could try ViperOneM8 2.5.0
It's a solid Sense based ROM with a lot of customization options.

You're talking about 2 different approaches now. You can either:
1) Flash a ROM that is supported by your (2.xx) firmware.
2) Update the firmware that matches your current ROM (but not sure what version that would be).
You don't need to do both (flash new firmware and flash a 2.xx ROM). Although you can, as long the ROM is supported by the firmware (otherwise you will still have broken WiFi and possibly other severe bugs).
Also, keep in mind that if you are s-on, you can only flash a firmware that is signed and corresponds with your CID.

It absolutely matters. NEVER EVER EVER flash a ROM meant for another device. If you are s-on, it probably won't flash anyway. But if it does, it either won't work, or may even brick your device.
You likely just didn't browse back far enough (or didn't use the proper search string, if you used the XDA search function) to find a 2.xx based ROM for the M8. ROM base 2.xx is pretty old, so I see a couple started on Page 5 of 7 in the M8 Development section. What I see are:

Sorry if I'm asking too many questions. If I go with the updating the firmware route first, do I have to do anything specific? Like for example update from 2.x.x -> 5.0. Or does it not matter what version I'm currently on to update to 5.0. Also, I'm seeing a lot of issues concerning which carrier the phone is from. Is there a way to check that? I *think* mine might be some asian branded version, but I'm unsure.
Also, I'm checking the phone's firmware and it's saying that it's 4.4.4. http://imgur.com/rbLpjl1

It absolutely matters what firmware you pick and whether or not it corresponds to your CID. For one thing, with s-on, you can only flash the firmware for your CID, plus the firmware has to be signed.
Another thing, the firmware will update your radio baseband version. So if you flash firmware for a different CID, you may change the band support, and find you no longer have 3G or 4G connection (depending on what firmware you flash, what bands used by your local carrier, etc.).
Also, don't confuse software version with Android version (you've mixed the 2 together above). The Android version is Google's numbering scheme. Software number is HTC's numbering scheme.
Software version 2.xx corresponds to Android version 4.4.3.
Android version 5.0 (Lollipop) corresponds to software version 4.xx.
Its been requested a couple times now that you do adb getvar all to determine your CID and MID. We can't help if you are guessing or don't know the carrier version.

The photo has nothing to do with your firmware number. The firmware number is best determined with adb getvar all, and is displayed as "main version".
What your picture shows simply means the ROM you flashed is based on Android 4.4.4, and software 3.28.401. The software number of the ROM is completely different from your present firmware number; and the very reason why your WiFi is broken.
I've already determined from the pic in your first post that your firmware is 2.xx (corresponding to Android 4.4.3). To get the more specific numbers (after the "2") you need to do adb getvar all.
Also, if you post the getvar output, be sure to delete your IMEI and serial number, as these are private info.

The first picture is getting the CID and MID by following some guide off of google, so I don't know if that's right or not.
The second and third picture are the adb getvar all that you suggested me doing.

See ... you're on T-Mobile network but your device is not a TMOB and not a EU but a TW device.
CID HTC__621
MID 0P6B11000
This is my suggestion to fix whatever problem you have currently (without S-Off).
1. Restore 2.22.709.3 TWRP backup as your device hboot is 3.18.0000
2. install 2.22.709.3 stock recovery after restore
3. do multiple OTA to the latest lollipop version : 2.22.709.3 --> 3.28.709.6 --> 4.16.709.9 --> 4.24.709.2
4. Then if you like to install custom ROM, install TWRP again and install any custom ROM that you like - now you should not have any wifi problem
All the needed files / how-to is here : http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860

You guys are absolutely amazing. Thank you so much for the help and patience. I followed all the steps (except for the multiple OTA updates, which I'm in the process of right now) and the wifi problem seems to be fixed.
On an off note, does it matter that in the bootloader, it says
*** Software status: Modified ***
*** UNLOCKED ***
?
And should I go through the process of S-Off-ing my phone? Does it benefit me to do it?
Again, thank you so much

UNLOCKED is fine. OTAs will install whether its locked or not. Better to leave it as-is (relocking only needed and recommended to run RUU or signed firmware zip).
The software modified flag is a bit puzzling. It usually indicated the ROM has been modified. If you installed the stock TWRP backup for your CID, it shouldn't say this. And software modified will prevent OTA from installing.
Are you sure you installed the stock TWRP backup (exactly correct software number) that ckpv5 indicated?

It depends on what you want to do with the phone. For most things (root, flashing custom ROMs, kernels, etc.), s-off is not needed. But it can be handy if you want to flash radios, modified hboots, convert to another CID or MID, and some other things.

The pics do not show the expected output for adb getvar all.
My guess is that you tried to run the commands same as the other (fastboot) commands, while in fastboot mode. adb commands can only be run while booted into OS (and with Debugging enabled in phone settings) or in recovery. Only fastboot commands work in fastboot mode.

That's the same as "TAMPERED" on hboot 3.18.0000 as seen on his first screenshot.
MODIFIED is on hboot 3.19.0000
That usually come after the bootloader is unlocked.
That can be change on S-Off device.

I installed the Venom ROM so that's probably the reason why it's showing that then. Thanks for everything guys

Somewhat correct. If the firmware is official (signed and encrypted) and for your CID, it will flash with s-on.
However, once the firmware has been modified in any way (as the one you tried clearly is) or otherwise not signed, you can't flash it unless you have s-off.
But I don't think flashing firmware is what you really want. You might be mixing up firmware with software (ROM). Firmware are the partitions that don't get changed when you flash a ROM. Firmware includes hboot, radio, and some other modules (WiFi, media, etc.). Since you need s-off to flash an "unofficial" firmware, and you are still s-on, you should still be on the stock firmware. And therefore, no need to "return to stock" since you still are stock.
What I think you mean, is that you want to return to stock ROM (since you are on CM12) and stock recovery. None of which require s-off. After that you can relock the bootloader. But it will always say RELOCKED instead of LOCKED, as the latter requires s-off. If you are selling or giving the phone away, RELOCKED should be sufficient for most folks. Although I highly recommend disclosing that the bootloader was previously unlocked, root, etc. to the new owner.

Flashing a firmware

Hello
My htc one m8 is the Asian version (HTC__044) , upon using getvar all, I noticed that my version-main was missing along with the os in hboot. If I were to flash a firmware, would I need to relock the bootloader? Would I lose my data on locking the bootloader? Also, im on base .401 , would I directly be able to flash a .707?
Thanks in advance.

If s-on, yes. Otherwise if s-off, no.
Also, be aware that with s-on you can only flash a firmware that is HTC signed/encrypted. Some are not, and require s-off.

How are you determining 401? From what I'm seeing, the stock software/firmware for your CID should be 707.
You should be able to flash 707 firmware (assume you want to update to Lollipop) on your version, provided the previously mentioned requirements are met.

Thanks for replying. I believe it may have been the rom ive installed that changed my firmware, along with the fact it writes .401 on my software information page. Yes the default firmware should be .707 which I believe is also the main cause of my inability to connect to 4g in my area.
So assuming I find a signed firmware for .707 I would simply be able to flash it on the .401? Or would I have to still relock my bootloader.
Also, would the empty os/ version-main be a problem and if so how do I fix it.
Thanks for replying as you've also helped me a great deal the previous time.

Flashing a ROM will not change your firmware. It does change software number, so if that is where you are getting 401 from, that is normal. Software number is just the base of your current ROM, not your firmware number.
Your firmware number is indicated on your bootloader screen under "OS" and also as "main version" when doing getvar all.

Are you s-on or s-off?
If still s-on, there is no way you could have ever flashed a 401 firmware on your phone. I still think you are confused between software and firmware numbers, and I don't guess that you ever flashed a 401 firmware.
If you are s-on, I still think you are on 707 firmware, and there is some other factor causing your 4G problem.
Yes, you need to relock your bootloader to flash 707 firmware while s-on. If you are s-off, you don't need to relock the bootloader.

It shouldn't be a problem. It will be fixed if you flash a firmware.
This bug was caused by older versions of TWRP. If you flash a current version of TWRP after flashing firmware, the problem should not re-occur.

We always like repeat customers, and satisfied ones.

So is it possible that I am actually on 707 but my rom is making it show 401? Im terribly sorry for my lack of understanding of this whole situation.
Would using the twrp app on the play store update twrp? It should fix the empty main-version ?

I know in the past, folks have often used the word "firmware" to mean the same as the ROM. But you should probably erase that notion from your mind. On this device, the word "firmware" is used specifically to partitions that are not flashed when you flash a ROM, and include hboot, radio, WiFi, Bluetooth, and others.
Yes, your firmware may still be 707 (which can normally be found as OS number on hboot screen, or main version when doing getvar all); while your software (ROM) which is shown in Settings>About>Software information can be 401. Firmware and ROM are 2 completely different things.
I've asked twice now, are you s-on or s-off?
wasdapple said:

TWRP Manager app will update TWRP, yes.
You can also just download the latest version and flash with fastboot, which is my preferred method: https://twrp.me/devices/htconem8gsm.html
However, this alone won't fix the issue of main version missing, I don't believe. It will only stop if from re-occurring. But the only way to get the main version back is to flash a firmware. After that, having an updated TWRP will stop if from main version displaying "blank" again. If you use an old TWRP, it will blank out the main version again.
Get it?

I'm sorry I kept forgetting to reply to that, I am actually s-on.
So for instance I want to be back on 707 I should just revert to rooted stock?

Than its simply impossible for you to ever have flashed a 401 firmware. Some of the firmware partitions (hboot, radio) are write protected with s-on, and can only be flashed with your CID version firmware (707).

Yes, rooted or unrooted should be fine.
But you will want to make sure your firmware and software versions match up. What are your hboot and radio numbers? Do you remember if you were on Lollipop before unlocking the bootloader?

My hboot would be 3.19.0.0000 and my radio is 1.25.21331147A1.06G
Yep I was on lollipop before unlocking my bootloader.

Not sure what you mean by "get back my 707", and you need to explain more clearly.
If the intent is to return to 707 firmware, its not needed, I'm confidant you already are on current 707 firmware. And flashing a ROM does not change your firmware (as I've already explained multiple times).
If the intent is to make the main version appear again, flashing a ROM won't do that either. As mentioned, you can only make that reappear by flashing a firmware.zip (not a ROM.zip).
If the intent is to just return to a 707 ROM base, then yes the ROM you linked will do that. But the only reason I see for you to do so, is to see if it helps your network issue. Using ROMs of other bases will not normally affect network service (as long as your carrier's APN is correct). And I've already linked you to stock 707 nandroid, which is probably the best baseline to troubleshoot from. Or are you not comfortable with the nandroid restore process?
Again, you haven't really explained what you are trying to accompish; so its hard to answer the question.

If the ROM is a similar enough base, it might be possible to dirty flash. But its not recommended, and still possible to have various severe bugs, or not even boot. Therefore, full wipe is normally recommended when moving between different ROMs (and often even major updates of the "same" ROM).
Any person flashing ROMs should know how to backup and restore their personal data (using Titanium Backup and/or other means) when moving between ROMs.

Sorry for my vagueness in my previous post. Currently in my phone settings, the build number is 4.26.401. , which is the base of my current rom? So supposedly if I flash an Asian wwe would I get my software base back to a 707 as in the link.
Also, you mentioned for me to flash my firmware as per my cid, which could be found in most firmware dumps? Would be it be possible to link one to me? And if I am in fact on a 707, do I still flash 707 firmware?
The reason why I an unwilling to go through with nandroid is that I am not exactly looking to restore to stock, I like to have customs roms and the root capabilities. My ultimate objective is to get back to 707, or at least get it to appear on my software information screen. To my knowledge, 401 is for the European countries and the basebands for 4g LTE is different, thus I am unable to find out why if I am s-on with my firmware and radio intact I could not connect to my local 4g LTE, and to my point of view, only through flashing a firmware affect everything.
Im sorry for this large amount questions and extremely grateful you have taken the time to tend to it. I sincerely apologise if I seem to keep insisting that my firmware has changed despite your reminders.

I've actually been trying to update the firmware on my M8 today as well, but when I go to "flashboot flash zip firmware.zip" I am returned the message "not enough space."
I've cleared the cache successfully, and that didn't open up enough space. I tried to delete userdata, but it wouldn't let me do it remotely.
So I'm a little confused as to my next move here...

Yes. You will get your software number back if you flash a 707 based ROM, such as stock.
So, here we go.
Download this 4.19.707.2 RUU onto your PC
When the download is finished, plug your phone into your PC, double click on the downloaded file, and follow the prompts. This will update you to Lollipop and you will be on the stock ROM again.
Since you are S-On, you will first need to relock the bootloader.
In fastboot (obviously) fastboot oem lock before you proceed with this.
Also, THIS WILL WIPE YOUR PHONE, so be sure to backup anything that is important to you.

Is the ruu rooted, or purely stock pre-root?

If the intent it to return to 707 based ROM to see if that helps your 4G issue, then yes the custom ROM you previously posted will do that. It will also make 707 appear for software number in the phone Settings.

I was more talking "if" you can find the 4.16.707 firmware. The main firmware collection I refer to doesn't have 4.16.707, just old 707 firmwares (which you don't want)]: http://forum.xda-developers.com/showthread.php?t=2696282
If the firmware can't be found, the RUU listed by xunxholyx is your best bet if you really want to flash the 707 firmware. But I really don't think this is needed. As I'm nearly 100% sure you are already on the current 707 firmware, and the only benefit of flashing the 707 firmware (by RUU) is to get the OS number to appear again on the bootloader screen and on getvar all (which is really not that important).
On the other hand, RUU to full stock may be a good way to troubleshoot your 4G issue, especially if flashing the 707 based custom ROM still doesn't fix the issue. RUU is not just a stock ROM, but a complete factory image, complete with bootloader, radio, etc.

Yeah, they are hard to come by. I was helping a user here six to eight weeks ago, and told him I didn't know of any Asia RUUs. He came back the next day replying that he found one, so I asked for the link and gave it to Sneakyghost and Alex (from AFH) to upload to androidruu.com
They have a few that aren't common there, and are always looking for more hard to find ones. If you come across one, you could PM me or Sneakyghost to have it added. Always nice to have a good RUU repository to go to.

Hey everyone. I'm having a similar issue, and I don't want to start a new thread, so I'm going to add on to this one.
I've been on AOKP since it was released for this phone, so I've missed out on some OTA updates. Every time I try to flash a Lollipop ROM I get all these weird issues (WiFi not working, systemUI crashes, etc.), and after reading a few threads, I believe its an issue with the firmware.
I tried going back to stock, but the only Nandroid backup I could find for my phone isn't compatible with my firmware (WiFi refuses to work, only data). So I was wondering what else I could do to update the firmware. Reading this thread, it looks like the RUU is another method, but I'm not too sure how to get started with that, or which one to use, as my OS in the Bootloader and my version-main is blank.
Any advice is appreciated, please let me know if you need more info.

HTC One M8s OTA not working

Hi,
I recently managed to root my HTC One M8s with TWRP recovery and everything works perfectly, except that I can't install the new OTA (1.16.401.1).
After searching I have flashed my recovery back to the stock for my version (which is 1.11.401.1) and tried applying the OTA again, but it still fails.
I downloaded the recovery from this website: ruu.lalleman.net/HTC_M8S%28QL_UL%29/Recovery/HTC%20Recovery/ (I can't post URLs yet).
Below is the error I receive when trying to update on stock recovery, TWRP recovery also gave the same error when I tried updating there.
(Code -1)
E:Find no match PARTITION: for package path @/cache/recover/block.map

E:Error in @/cache/recovery/block.map

From what I can see my build fingerprint is incorrect, but I have no idea how to fix it...

Seems to me it's likely that you've altered some system files while rooted and the Ota doesn't like it.
Now, I don't own an M8s...i have an M8, but I'd say the easiest route would be to flash your stock ruu again. After that the OTA should work.
It's that or figure out what system changes have been made and correct it. Xposed can mess you up, Uninstalled system apps can stop the Ota... MODS that changed system files... Etc. The Ota us looking for a stock system, then it updates it.
Good luck!

Thanks for the answer, I will see if I can try this solution tomorrow. I just have 2 questions:
What does the RUU do exactly? Should I see it as a complete stock reset of my phone?
And can I simply flash it using fastboot or is there a special method for a RUU?
My previous phone had an automated root and I always updated with OTA afterwards so I never flashed before now.

Im on the same boat. Tried to sim unlock by rooting and playing with CID but didnt work, now ive a rooted m8s and no ota. Tried to ruu but kept getting an error something like not enough space although i had 10gb free, cleared cache rebooted. Cant even factory reset. If anyone know how to unroot it and bring it back to stock that would be fantastic. Kind of want to delete the "flag" too make it "LOCKED" and "OFFICIAL" incase for warranty. Any ideas?

You guys have flashed 1.16 before, haven't you...?

When I got my phone I updated with OTA to version 1.11, after that I flashed TWRP recovery and rooted my phone. Now that OTA 1.16 is out I tried to update but couldn't, so I tried to flash back to stock recovery but it still wouldn't work because of the error above. Now it would seem that I am doing this the wrong way, and you cannot use OTA on a rooted/unlocked/custom recovery M8s.
Manual OTA flash worked on my previous phone with root which was an ASUS Padfone Infinity A80 as ASUS would release them on their own website for you.
Apparently HTC does not do this, or I am not looking in the right place.
I have never flashed a RUU before, and I don't know how to lock my bootloader again. From what I understand, every time there is a new OTA I will have to lock my bootloader, flash original recovery, flash RUU and then update. That sounds like a lot of trouble every time a new OTA comes out.
Is there no way to manually flash the new OTA without losing root, custom recovery and locking the bootloader? Will I have to follow these steps every time? Also I use the built in back-up to Google as well as HTC back-up but I don't know if all my data is in those back-ups or if I will lose something.

If you restore a RUU, and afterwards don't flash your recovery and boot partitions, You will see "Software status: official" in fastboot.
Now here's the trick: if you just boot a custom recovery with "fastboot boot my_recovery.img" (TWRP for example) then it will boot TWRP, but you can make the modifications to your system partition without losing "Software status: official" in fastboot.
So: If you just boot your recovery with 'fastboot boot' and don't flash anything, you can make all the modifications you want and still be able to install OTAs later, I think. I've rooted my phone, even installed XPosed, done all kinds of funky things to it but Fastboot still shows me that I'm on official software.
How does that sound?

So since there is no decent guide at all about flashing RUU for a HTC One M8s (the s makes a difference!). I have assumed that I need to have the bootloader locked first, as I unlocked it. According to all the M8 guides I have to gain S-OFF before I can lock the bootloader again. So I followed a guide to wipe with TWRP and flash a ROM called InsertCoin so that I can S-OFF my phone.
Now after going through the ROM's setup my phone is stuck in a bootloop, constantly trying to boot up. There is NO way at all for me to get it to stop, it just keeps booting the entire time. Not a single combination of buttons is working. Good thing the battery is non removable. How am I supposed to fix this? I've tried every volume up/down/power combination possible. The phone just boots to the HTC - Power by Android screen, shuts off after about 5 seconds and then repeats the same thing over and over. I can't turn it off and I can't get to the bootloader either.
What I need is a guide that tells me all the steps required to get an HTC One M8s (NOT M8!) back to 100% stock. This means, stock ROM, stock recovery, locked bootloader and S-ON. I am getting extremely frustrated by the lack of information and the amount of redicilous things I need to do just so I can root my phone and have OTA as well.
All I want is root on my phone for 1 app that I use with my car radio and I want to be able to update to the newest OTA afterwards, is that really so much to ask?
I am fine with installing a custom ROM with root and easy updates too, as long as the damn phone will boot after installing it and it's actually made for the M8s.

Deleted......

Well I finally managed to get the damn thing to the bootloader, and I've used "fastboot oem lock" to relock my bootloader. It now shows ***Software status: Modified ***, *** RELOCKED *** and ***Security Warning ***.
I will now have to go to my parents where my laptop is to be able to copy the RUU to my SD card, from what I understand it has to be named 0PKVIMG.zip and then it should automatically install.

Now the phone says it can't find the image or the image is incorrect.... It searches for, 0PKVDIAG.zip, 0PKVDIAG.nbh, 0PKVIMG.zip or 0PKVIMG.img. and it seems to find 0PKVIMG.zip and loads it but it cannot find the .img file and does absolutely nothing. Am I supposed to have both?

So it turns out that the RUU zip from http://ruu.lalleman.net/HTC_M8S%28QL_UL%29/RUU/ is actually not correct and I had to use rom.zip which was inside the folder. The phone is now running the "update" as it calls it. Fingers crossed...

Yes, possible you need to use rom.zip inside the zip, depending on the version, but I think this applies to 1.16 which I advice against using for reasons previously specified.

By the way, I did write an RUU restoration thread specifically for this subject. Did you not find it?

Apparently I also needed to use the rom.zip for the 1.11 version, in the meantime I have also updated with OTA to 1.16. Afterwards I also unlocked my bootloader, restored my settings and installed SuperSU by booting TWRP. Let's hope the next OTA still works...
I did read your thread but I got stuck at first on relocking the bootloader, as I couldn't find the exact instructions for a while. Afterwards I got stuck on flashing the RUU because I didn't know that I needed to use the rom.zip file to get it to work.
After all that I got quite frustrated and I just wished there was 1 thread with instructions for everything (unlocking, relocking, flashing, compatible ROMs, booting to keep OTA, etc.) which is why I was angry at the time and couldn't properly read everything or find solutions. In the end it all worked out so far though.
I would ask you to create a compilation thread though if you wanted to improve the available information. Either way, thanks for the information that you've already provided.

The next ota won't work because you rooted it. Root changes binaries which lead to a fail on ota.
You need a non rooted (read : never rooted before) stock rom.

You need a non rooted (read : never rooted before) stock rom.

So in that case I just unroot it before updating then?

Read my post again...... "a never rooted rom" so that means you need a stock rom before its ever been rooted. NOT an unrooted one because it leaves traces which will cause the ota to fail !
People should learn to create a nandroid backup before flashing ANY mods/superuser.zip/roms etc......etc

Well developers shouldn't make this such a hassle... My previous phone was an ASUS Padfone Infinity (A80) and it didn't receive any OTAs after being rooted but ASUS simple lets you download the firmware updates on their website and then you can manually update it without any problems. If HTC provides a bootloader unlock, why can't they allow OTA or at least provide manual firmware updates?
I wouldn't mind using a custom ROM either but I have no idea which ROMs work for the HTC One M8s. Would any M8 ROM be compatible? The phones aren't identical, the "s" is there for a reason...

I would say that M8 roms wouldn't be compatible, and could even mess up your device badly. Sorry!

Your point of view is a bit off if you ask me. Developers (in this case HTC) do not have to support custom modding of your phone. They support the device in the state you buy it !
If you want to mod it that's YOUR call not theirs. Do some homework before modding it. Getting a phone back to stock for future updates is relatively easy but many people don't read first how to as they think it's not important.
HTC has no obligation at all towards you regarding custom software !
And indeed M8 roms do NOT work on your M8s !
