M8 No OS After Flash

Hi,
Having issues trying to put SuperSU on my M8. Heres what I've done:
- Unlocked bootloader
- Fastbooted TWRP on the phone
- Tried Flashing the ROM, says No OS installed. Rebooting stops at Android screen
- Tried downloading RUU and going back to stock, however the RUU tells me that there's an error and it can't continue.
- Tried switching between TWRP and CWM.
- Tried sideloading from my pc with a few different versions of SuperSU
Nothing seems to work.
Can anyone point me in the right direction?
Any help will be greatly appreciated.
If there's any more information you would like me to provide, just let me know.
Thanks Again,
Nick

Having issues trying to put SuperSU on my M8. Are you trying to root the stock ROM, or flash a custom ROM? Because they are 2 different things, with different approaches. And your steps described below contradict each other on this matter..
Heres what I've done:
- Unlocked bootloader
- Fastbooted TWRP on the phone What version TWRP?
- Tried Flashing the ROM, says No OS installed. Rebooting stops at Android screen Which ROM exactly? Did you try another ROM? Did the ROM install properly (any error messages in TWRP when you flashed?
- Tried downloading RUU and going back to stock, however the RUU tells me that there's an error and it can't continue. What RUU (exact file name)? What was the error message and error number? These are important, as they tell you why the RUU failed.
- Tried switching between TWRP and CWM. Not recommended. CWM hasn't been updated in a long time, and can cause some problems in itself.
- Tried sideloading from my pc with a few different versions of SuperSU If you have no OS, flashing SuperSU isn't going to help matters.

Additonally, do fastboot getvar all, so we can see more info about the phone. Delete IMEI and serial number before posting.

Are you trying to root the stock ROM, or flash a custom ROM?
Originally I tried to put SuperSU2.37 on there, that didn't work, so I tried SuperSU2.77, which failed. I then tried to RUU to stock, which I'm having issues with also.
- What version TWRP?
3.0.2-0
- Any error messages in TWRP when you flashed?
It doesn't show any errors. After it's finished it says No OS Installed, are you sure you want to reboot?
- What RUU (exact file name)?
RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4.exe
Error 155
Please get the correct RUU and try again.

SuperSU version 2.37 is really old. Not sure how you even came about it (old toolkit maybe?), that version probably wouldn't work on Lollipop, much less your current Marshmallow firmware.
SuperSU 2.77 should be okay, its current and updated for MM. I might suggest the latest "STABLE" version, which is 2.76 from here. But honestly, they are all pretty stable from what I've seen, and it probably wouldn't make a huge difference wither way (the version 2.77 should be ok). And it seems like the main problem is that we need to solve the "No OS" issue before proceeding.

My guess, is that you did something to delete the OS, that maybe you missed when listing the steps you did. Since, I can't see how OS could be wiped/missing with what you indicated. At least up until you tried RUU, since if you relocked the bootloader to RUU (which is a requirement unless you have s-off), that wipes the OS (so maybe you just have the order of steps you tried, mixed up?).

That RUU isn't for your version. Maybe the "WWE" in the file name has you confused, but its actually for the US Developer's Edition. What you need would have version number with "401" instead of "1540", but you would only know that from experience or reading it somewhere on the forums.
You should be able to use the following RUU (zip format, not exe - so follow the instructions to flash): http://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Alternately, restore the stock TWRP backup 6.12.401.4 using the file and instructions here: http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Not sure whether your bootloader is currently relocked or unlocked, as you haven't indicated, either way. It needs to be relocked to RUU, or alternately it needs to be unlocked to do the TWRP stock backup method.

Haha, I find that a good way to respond to numerous statements or questions in a previous post; rather than using multiple quotes. And red just seems to stand out well, compared to other colors! But love your observation.

Thanks so much!
I wasn't sure which files i needed for that walkthrough, until you told me which ones.
Phone is back up and working fine.
Thanks again mate

htc m8 - bricked while updating ota stock marshmallow

While, i dint do much. My phone showed, i have an update that could be installed. I went ahead and did so. But unfortunately it wasnt successful. Now all i have is htc logo. I can also get into fastboot mode. I tried an RUU:
RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4 doesnt help. I did unlock the bootloader by going to htc dev and using the hasoons tool kit.

Also i should say i tried to copy the rom.zip from the ruu.exe (temp location). Tried flashing it, either i get a 24 parsing error or remote 32 header error. so thats a long story short. I am in India by the way. And i believe the phone is global version.
If in case you want any other info i can provide you that. Can you help me get back to the stock rom. Marshmallow

That RUU won't work, its not for your Euro "401" version, its for the US Developer's Version (1540). You need RUU 6.12.401.4 which can be found in .zip format here (don't know of a source for exe format): http://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
You also need to relock the bootloader to run the RUU. Instructions to do so, are also included on the link above.
Did you unlock the bootloader to RUU? If so, you have it backwards. RUU requires bootloader LOCKED or RELOCKED. RUU will never run with bootloader unlocked (unless you have s-off, which you don't).

I downloaded the correct version of Marshmallow from Android Ghost : url below.
https://www.androidfilehost.com/?fid=24369303960687057
Make sure u download the htc fastboot files: Google is ur friend.
Place the image in the same folder as the htc fastboot files are.
rename the file to 0P6BIMG.zip( remember not to add two zips at the end.,windows generally hides the extension
Now open ur command prompt.
naviagate to the htc fastboot folder , i my case, i put in c drive
so it would like c:\htc_fastboot_files
Now Voulme Down Button and then press the power button.
In my case i had to use Power+Volume up to reboot the phone . And the moment it rebooted i pressed just the vol down button.
So we would be in Bootloader. Now switch phone to fastboot mode.
Navigate using volume buttons and power button to enter.
in fast boot mode
bring up ur command prompt:
We are already in the fastboot file folder. like i mentioned before: c:\htc_fastboot_files
type fastboot get var all
look for this info: (bootloader) version-main: 6.12.401.4 ( This might be different case to case, according to this you can search for relevant ruu, just google with the version number firmware)
Now htc_fastboot oem lock ( To relock the bootloader)
htc_fastboot oem rebootRUU
htc_fastboot flash zip Firmware_xx.zip ( in my case its 0P6BIMG.zip)
Once the flash completes, you will have a window which says Flash complete. OKAY. Mind you it takes some time.
After this,
htc_fastboot reboot . Thats it. Phone will take quite some time to reboot and complete the process.
My phone was up and running from here. But in case of errors. You might want look down.
IF IT SAYS "FAILED" do not immediately reboot the device If you reboot with a FAIL It could brick! If no flash is being accepted you have to find out what is causing the malfunction before rebooting your phone. Keep it alive while trying to figure out the error. It might be your cable, your USB ports (don’t use hubs! Always direct-mainboard connections), it might be USB 3.0 which is not good yet, it might be bad configuration of your ADB and Fastboot...
The least dangerous FAILED messages are listed below and are safe to reboot (below this section you find CRITICAL errors, please observe):
Safe to reboot / Flash didn't happen Errors (if you encounter one of them, you can just reboot. Nothing changed):
- 12 signature fail (unknown yet but safe to reboot)
- 23 parsing image fail (means something wrong with the image in the zip)
- 24 android-info fail (means something wrong with android-info.txt in the zip)
- 32 header error (means the zip couldn't be read and unzipped properly)
- 41 Wrong Model ID (means it's not the right device)
- 42 Wrong Customer ID (wrong CID means you gotta swap CID first as explained below)
- 90 hboot pre-update (means it only flashed hboot and you have to run the process again immediately to flash all other partitions WITHOUT a reboot in-between).
- 99 UNKNOWN usually indicates you are S-ON, sometimes other Security related issues.
- 130 wrong model ID (seems it's the same like 41, just that it shows in the FUU as 130.
- 155 seems to indicate different things. It can mean: 1.) You need to relock bootloader (If S-ON); 2.) You cannot run the RUU/FUU because the software versions of ROM, Firmware and RUU/FUU don’t match.
- 170 Check USB - FUU won’t run because of not working ADB.
In fact, if it aborts before the "(bootloader) start image[hboot] unzipping & flushing..." line it actually didn't write anything and you can probably just reboot. If you see it flashing stuff though (the stages after that line) and then it stops with a FAILED, chances are a little higher that something is now broken. In that case do NOT reboot but do as i said above.
For Error 12 “signature fail" do:
- might indicate that a signed firmware package is required. This would only happen with S-ON phones though.
For Error 23 "parsing image fail" do:
- change image names in the zip to stock image names like “hboot.img" or “radio.img" or whatever failed there....
For Error 24 "android-info fail" do:
- check that your ZIP isn’t some HTC OTA or anything thats got no android-info.txt - those cannot be flashed with fastboot flash zip nameof.zip command.
- check that your zip has a good MD5 and is not broken, check android-info.txt etc...
For Error 32 "header error" do:
- Sorry i haven’t found the exact cause yet and don’t know a definite solution.
- Make sure there is only one . (dot) in the filename, before the extension. fastboot reads anything after the first dot it sees as the extension. If that is not zip, it fails.
- If that doesn't help, you can also try: make the zip new with recommended settings, re-run the command, check your connections...
For Error 42 "Wrong Customer ID" and: 41 "Wrong Model ID" do:
Code:
htc_fastboot getvar all
Read that output, take note of your CID and MID and then edit the "android-info.txt" in your firmware.zip accordingly (For Wrong MID change the MID in the text, for wrong CID add your CID to the text).
Alternative method for MID and CID errors:
go SuperCID. Do:
Code:
htc_fastboot oem writecid 11111111
You can change back to any desired CID after a successful firmware flash. Notice: this command only works on S-OFF phones (which you have already of course or else you wouldn't be here).
For “Error 90 hboot pre-update..." do:
- Run the same flash command again which you just ran (press arrow up on your keyboard to get to the previous command in console)
- Don’t reboot in-between! (It wouldn't brick you but it would just make you run the flash command twice again)
- This might be caused by the newer encrypted RUU's, they need their hboot to be flashed first so it can then decrypt the rest of the ROM.zip. Look at an encrypted ROM.zip from a RUU, you will notice that you can mostly extract the hboot without decrypting the ROM.zip, but you can't extract much else.)
For “Error 99 UNKNOWN" do:
- Check with other zip’s if they work!
- Check if your S-OFF is correct
- You are S-ON? Then almost definitely this means the ZIP is not signed - get an unmodified zip!
For “Error 130 wrong model ID" do:
- Please refer to Error Code 41/42.
For “Error 155 relock bootloader" do:
- Since my thread works only with S-OFF phones anyway, this error can be read as: you need to S-OFF first!
- Error 155 can mean that you need SuperCID. On a few occasions this was shown when the RUU/FUU refused to run because of a wrong region lock.
- Lately, Error 155 has occurred when a FUU was launched from within android. When encountering a FUU error 155 with the process stalling after the rebootRUU (stuck at black screen with silver HTC logo), please just restart the FUU and leave the phone in that mode, or reboot the phone, then reboot to bootloader, then do “htc_fastboot oem rebootRUU” and then launch the FUU again (thanks @anarchychris for pointing it out).
- run the fastboot command “htc_fastboot oem lock" - only applies to S-ON phones that want to update the firmware with a stock OTA package (not offered on this thread!!). Stock OTA files sometimes need a locked bootloader.
For “Error 170 Check USB" do:
- Sometimes shown when running a RUU or FUU. Indicates issues with drivers. One way to solve is to run the ARUWizard with the phone already in Fastboot mode. Else you will have to re-install HTC Sync manager. Also, avoid USB 3 ports (the blue ones) - they have a complete new driver stack and that doesn't work well currently.
NOT safe to reboot / Flash (partly) happened Errors (if you encounter one of them, DON’T reboot:
- 152 Image Error - Phone Screen shows a little triangle beside a full green bar
For “Error 152 Image Error" do:
- Error 152 is quite rare, have seen it only once with a friend’s phone and it aborted the flash nearly at the end. The flash was started by the FUU. We could resolve the matter by NOT rebooting the phone and flashing the zip again through a manual fastboot flash as outlined further up.

I'm not familiar with Android Ghost. The text looks like its just copy/paste stolen from XDA (which is often what a lot of random "root" or similar websites do).

Yep. That's straight up stolen (copy/pasted) from @Sneakyghost's threads.

Yeah, hard to tell what OP is talking about, if they don't even get the name right.
Also completely unnecessary of him to clutter up the board by copy and pasting huge amounts of text when a link can be provided (or refer to a thread, if he can't link).

What exactly did you try to flash (file name and source - describe the thread or obfuscate the link if you need to)?
You understand that a firmware is not a ROM, and a stock recovery is not a ROM?
You need to describe in detail, exactly what steps you have tried. Otherwise, I have no idea what you are trying to do, or how to fix it.

Yes it is. This phone is a different device used by my sister.

i too think the same. i used this just to see asian ruu works or not.
What exactly did you try to flash (file name and source - describe the thread or obfuscate the link if you need to)?
First after a lot of reading, i came to knw you cannot ruu with custom recovery installed. for that i need to have stock recovery. Now i have no clue which one to flash. However, i went ahead and flashed 6.20.709.2 stock recovery. Now i tried
flashing that ruu downloaded from gsm developers. but i failed with it.
You understand that a firmware is not a ROM, and a stock recovery is not a ROM?
Being very honest, i have very little knowledge, its a new learning for me. I never knew firmware is not a rom and recovery is not a rom.
You need to describe in detail, exactly what steps you have tried. Otherwise, I have no idea what you are trying to do, or how to fix it.

Now to revert back i am trying to find out which ruu i should download?
Now am downloading another ruu from this link : https://www.androidfilehost.com/?fid=24391638059058090
it says : M8_UL_m60_SENSE70_MR_hTc_Asia_Tw_6.20.709.2
My device id belongs to India when i googled hence i m searching for these ruu. I wanted to try sunshine s off so that change the mid and cid to eu version and then try different ruu. Sunshine keeps giving me an error while running the initial tests it requires an non debuggable boot.img. So that doesnt help either.
do you require anymore info ? i can give u remote access if it requires.

You didn't even provide any of the info I requested in my last post.
All you did was provide yet another link, with no info of how you found it. So I have no idea if its legit, signed, etc. (if its not signed, you can't flash it with s-on).

All you did was provide yet another link, with no info of how you found it. So I have no idea if its legit, signed, etc. (if its not signed, you can't flash it with s-on).

I can't tell what that is. Its not a valid file name, nor is it a valid link. Also looks like its from some random website "gsmdevelopers.com" (which I am not familiar with) so I have no idea if its a valid/safe file or not.
i too think the same. i used this just to see asian ruu works or not.
What exactly did you try to flash (file name and source - describe the thread or obfuscate the link if you need to)?
First after a lot of reading, i came to knw you cannot ruu with custom recovery installed. for that i need to have stock recovery. Now i have no clue which one to flash. However, i went ahead and flashed 6.20.709.2 stock recovery. Now i tried
flashing that ruu downloaded from gsm developers. but i failed with it.
You understand that a firmware is not a ROM, and a stock recovery is not a ROM?
Being very honest, i have very little knowledge, its a new learning for me. I never knew firmware is not a rom and recovery is not a rom.

This is completely incorrect. You can RUU with custom recovery installed. You only need stock recovery to do an OTA update, which is completely different from an RUU.

How on earth would you ever even flash that? The file name is not an exe or a zip: 0P6BIMG_M8_UHL_M60_SENSE70_MR_hTC_Asia_India_6.15. 720.2_Radio_1.29.214500021.12G_20.72.4196t.01_F_re lease_469495_signed_2_4_gsmdevelopers.com (1)

That RUU won't work (wrong CID and MID). You need a RUU that has version number"720" , not 709.
The number in the position x.xx.720.xx specifically refer to your version M8 (CID and MID).
EDIT: fixed a typo, the number in red in the last line should read 720.

Okay, one really important point I need to make: One should absolutely be sure to research and learn, and understand all the processes before modding any phone.
In particular, you shouldn't be modding the phone, without knowing how to return it to stock. You should always have an "escape" strategy to revert the changes you make, return to stock, etc.
Did you make a TWRP backup before flashing a custom ROM? You should always do this, its just basic good practice when modding phones. If you had done so, you would have an easy way to restore the stock, unrooted ROM.

It won't work. You need version numbers with 720, not 709.
I see in my last post, I said you needed 720 (which is correct) then a typo which implies you need 709 (not correct). So there may have been some confusion or conflicting info there.
Also, that version is too old (software number 1.54). You can only run RUU with equal or greater version than the firmware on the phone, which in your case is 4.xx.

RELOCKED is the important part. Not sure why you got in error , but it looks to be properly relocked to run RUU.
Was it RELOCKED or UNLOCKED when you tried the RUU 6.20.709.2 and got Error 12: Signature Error?

Sprint M8 Stock Roms

Hi, I made this post in the Sprint section a few days ago, but figured I'd post here as well to see if maybe this section has more traffic. If that's not allowed, I apologize in advance.
https://forum.xda-developers.com/sprint-htc-one-m8/help/stock-roms-t3669676
Basically, I'm looking for a stock rom for Sprint that would work with 1.54.651.8 firmware. All the links I can find on the forums seem to be dead.
Alternatively, a nandroid backup or way to extract the rom from the 1.54.651.8 RUU I do have (but won't successfully flash for whatever reason)
Any help would be appreciated. Thanks!

A custom ROM would need to support the Sprint M8, and be based on 4.4.2. Most any newer (newer than KitKat) ROMs will suffer major incompatibility with your ancient firmware, including extreme long boot time or no boot, and broken WiFi.
Suggest stocking with updating the firmware. Is the device s-on or s-off?
Problems with the RUU while "sending" are usually on the PC side. Try to re-install HTC drivers, try another USB port (USB 2.0 works best), and try another cable. Or even try another PC if possible.

Yeah I was able to find one custom 4.4.4 ROM (It was labelled 4.4.2, but it works so I guess it's close enough). There are just a few issues with it and I've always been more of a stock person anyway so I'd rather use a stock rom if I have the option.
As far as updating firmware, I am S-ON - I only originally rooted for a wifi hotspot app, so I didn't have a need to go S-OFF.
I guess it wouldn't hurt to give the RUUs a shot on a different computer. I'll just have to talk a friend into letting me install the drivers and giving it a go. One thing I'm not sure about - is it safe to go straight to the lastest RUU on HTC's site? I was willing to try it back when I had no rom at all, but now that I have a custom rom that mostly works, I'd rather not totally crap the bed.

You can "skip" RUUs, and go the latest. However, you may (probably) need to update to the Marshmallow firmware anyway, before you can RUU. There is a strange limitation on most US version M8, where the RUU will fail with Error 155, if you try to go to Marshmallow from any former version (be it Kitkat or Lollipop) without first updating the firmware.
So the steps would be:
1) Relock bootloader
2) Flash to Marshmallow signed firmware (Sprint), in fastbootRUU mode
3) RUU to Marshmallow
4) Unlock bootloader again
5) Flash TWRP, root, and do whatever mods you want
Seeing as RUU will also wipe the phone. All this might be more than you want to do, if you are fairly happy with the phone as it is.

I don't so much mind the wipe, but I am a bit nervous about updating the firmware since that sounds like it could leave me in limbo if the RUU still didn't want to work for whatever reason. I guess I'll search around for where I can get that firmware and the procedure of how to do it and see how comfortable I feel with it in case I go that route.
If I knew for sure that it would all go through, I'd be fine with the reset. But that seems to take the attractive part of the RUU away in that it's no longer an "all in one" or one step process. (Not counting unlocking/relocking the bootloader since that's a quick and easy thing).

The firmware is posted in the same thread as the RUUs. And instructions on how to flash, as well.

You can also opt for the Lollipop RUU (does not require flashing the firmware first). While not the latest, it's obviously more updated than what you presently have. And most of the current MM ROMs should work with LP firmware. There isn't much difference in the firmware it seems, for LP versus MM. Much different from KK to LP, which causes the problems I mentioned earlier (if you try to run KK firmware with LP or MM ROMs).
For maximum compatibility, matching the firmware is usually best. But I was running LP firmware with MM ROMs for a while (was simply to lazy to flash the MM firmware or RUU).

Ok so it sounds like the easiest option for me at this point is to grab a Lollipop RUU and try to flash it from a new computer with a fresh install of all the drivers. That way, at least if it fails to recognize my phone like the newest one did, I'll still be where I currently am with the stock (though outdated) firmware and custom rom.
Otherwise, I'll keep my fingers crossed that someone stumbles across this thread that has a meticulous archive of all old stock Sprint roms
Thanks so much for all your help and answering my questions so quickly. Much appreciated.

"Jail break" is a term specific to only iPhones. There is not such thing as "jail break" on an Android device. I assume you mean s-off, or some other mod? I can only guess, if you don't use the specific and proper terminology.

All in one Toolkit is obsolete, you shouldn't be using it. It contains a very old version of TWRP which will cause problems for many folks.
System partition is the OS/ROM. Should be obvious, that wiping the system partition results in no OS. Can't boot to an OS that isn't there any more. If you didn't know what the result would be from wiping a partition, you should be touching it in the first place!!!! Those options are listed under "Advanced" for a reason. If you aren't an advanced user, don't mess with them, unless you are following directions form an experienced user, or know what the result is going to be.

Not enough info to know why the RUU failed. You linked a post with multiple RUUs, so we don't know which one you tried. We also don't know your current phone configuration.
Which version number RUU did you try? For HK version, you typically will need to flash the one that contains the digits "654". The RUU with digits "651" is for non-HK Sprint version. Assuming CID/MID has not been modified (which we don't know, if you don't provide more info).
Post specific info about your phone. Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
If the phone is s-on, you need to lock it in order to RUU. I don't know if you are s-on of s--off.
You can't run a lower number (downgrade) RUU unless you have s-off. Again, I don't know what version number RUU you tried, your current version number on the phone, or whether you are s-on or s-off.

Hi Sir,
Thank you for replying. Sim Unlocked from mobile store. actually I also don't know witch method they are using to unlock. After unlocking network signals showing in GSM mode. When I am changing to LTE mode again signals disappeared. In GSM mode incoming calls are not working. SMS both incoming and outgoing working fine.
I tried to change CID and s-off but it's not working.
TWRP I used version v2.7.0.2 these recovery installed from all in one twrp (sprint). when i come back in to bootloader it will asking No OS installed are you sure you wish to reboot?

LTE is difficult (maybe impossible) to get working in cases where the device is not intended for your region/carrier (which I assume is the case, that you are not located in US, on the Sprint carrier). GSM should work (as you indicated) as well as 3G (HSPA) provided that your carrier uses a band(s) supported by the Sprint version M8
I tried to change CID and s-off but it's not working. I don't know what that means "it's not working". Most folks who say they have trouble with getting s-off, are trying the hopeless waste of time, which is trying to usethe long obsolete "free" s-off method of firewater. It's never going to work.
Also, you should also be careful here, when changing CID. Only use a Sprint CID, or SuperCID with a Sprint firmware/RUU. Trying to use any other firmware or RUU will result in a radio brick (possibly permanent).
TWRP I used version v2.7.0.2 these recovery installed from all in one twrp (sprint). when i come back in to bootloader it will asking No OS installed are you sure you wish to reboot? That version is too old (over 4 years) and you should have used current TWRP. This was probably caused by using the toolkit (which I mentioned is not advised anymore). Old versions of TWRP was not compatible with Sprint M8 (it had it's own "CDMA" version TWRP) and it probably caused the wrong partition to be overwritten.
What was I do is
First Re-locked bootloader using with all in one and rename firmware as 0P6BIMG.ZIP then flash from SD Card Installed Successfully. Bootloader also showing OS version 6.20.654.3 Try flashing firmware again, the number should show up in getvar all (below) under "version-main". Flashing firmware twice is usually a good idea.
Next using exe file "RUU_M8_WHL_M60_SENSE70_SPCS_MR_Sprint_WWE_Harman_6.20.654.3.exe" everything going well when the process bar reaching to 100% then it's showing error 155. I Checked the error guide provide by exe file there Unsupported RUU please try again with supported RUU.
Error 155 is common, if flashing a US Marshmallow RUU, without being on the matching firmware. Flashing firmware again, as indicated above, may solve it.

Return to stock firmware

Hello everyone,
I'd want to sell my HTC One M8, unlocked, with recovery and with a custom ROM. I'd want to return to stock (just flash the old firmware, without lock the bootloader).
How can I flash the old original firmware (maybe no-brand firmware)?
Thank you

First, I suggest you avoid using the word "firmware" the way you are. On this device, there is a package specifically named "firmware.zip" which is a small zip (around 80 MB) that contains a few partitions necessary for the ROM to work (hboot, kernel, radio, etc.) but does not actually contain the stock ROM itself (which is much larger, about 1.5 GB).
In fact, taken literally, flashing the stock firmware (with s-on) without then flashing RUU or ROM, will render the phone unable to boot to OS.
If you mean stock ROM, say stock ROM. If you mean RUU, say RUU.
You can restore a stock TWRP backup (stock ROM) and flash stock recovery to the device (without relocking the bootloader). But if there is an RUU available for your version, it's probably easier (and a better idea) to relock bootloader and RUU back to full stock.
In any case, it's probably not a good idea to sell the phone with the bootloader unlocked, unless the buyer is specifically asking for that (and aware what that means). Leaving it unlocked, leaves them vulnerable to a variety of issues, which they may not be remotely aware of. Most folks are not tech savvy, and will have no idea what an unlocked bootloader even means.
If you want more help (finding the right TWRP backup, RUU, etc.) do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

@redpoint73 Thank you for your satisfactory answer.
So, I would want to lock bootloader and then flash a RUU.

I've found, on my backup hard disk, three files:
3.31.901.9_ckpv5.zip (with relative recovery.img) (info in attached image)
4.20.901.3_ckpv5.zip (with relative recovery.img) (info in attached image)
2.22.901.5_firmware.zip (with relative recovery.img) related to 4.4.3 - TIM__401
Could they be useful?
Thank you very much.

EDIT: The first 2 files you listed are TWRP backups. You can restore the backup 4.20.901.3 using the instruction listed here: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
The firmware file, as mentioned before, is not a full RUU or ROM, and will result in no boot.

3.31.901.9 will likely fail due to being a lower version number than what is on the phone (can deduce from the current radio baseband number, that the current OS number is probably 4.20.901.3). And you can't flash a lower version RUU ("downgrade") with s-on.

Thanks!
So, how can I flash the 4.20.901.3 RUU?
Thank you.

Actually, looking at the files in your screenshot, I realize those are not RUUs. They are TWRP backups.
I don't know if your version has RUU.
So you can restore the TWRP stock backup that you have (4.20.901.3 as I stated before is still correct) using the instructions in the following thread: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
You can also restore stock recovery 4.20.901.4, which you can download from Post #4 of the same thread.
Do not relock the bootloader in this case. I don't know if there is a way to revert to locked/relocked bootloader, and have a working phone, since there is no RUU for your version M8, that I know of. So it would be best to inform prospective buyers that the bootloader is unlocked.
My apologies for any confusion there. I've edited my previous post, to avoid any confusion by others reading this thread.

Ok, I will use TWRP to install my stock backup.
I would want to know if it could be possible to flash a no-brand RUU, instead of the stock one? Thank you.

No, it's not possible to flash an RUU intended for another version M8 (another CID) unless you get s-off (need s-off to change the CID). And the only working method to get s-off is by sunshine ($25 US), and it's not worth spending money on a phone you are trying to sell.
Doing a quick Google search, there is an RUU 4.20.901.4, but you have to pay money to download it. Again, not worth it. Use the TWRP backup approach, as already described.

Need Help with HTC m8 Demo Unit *Stock Rom* - Wants to Flash Custom ROM

Hey everyone!
I just got HTC M8 from a friend, and figured out it is a demo unit. It comes with a demo app, which I am unable to get rid off. It was firstly rooted and mistakenly I removed the internal storage. After all the mayhem, researching for hours on this forum, I am finally able to get my device back running but still the demo app is there. I am unable to make any changes in developer options or through control center. I am new to all modding, HTC, Android and custom / stock roms.
I have few questions after reading a lot. After accidentally deleting the OS, and wiping internal memory - I was able to get it back, but now wants to run a custom ROM on it but not sure if I am able to do it with current status of my device.
Information about device:
HBoot: 3.16.000
S-ON
HTC__002
Unlocked Bootloader
TWRP installed (but throws error whenever I try flashing a zip file)
The question: Can I install a custom rom without getting S-OFF and if yes, which custom ROM can I use on my device? I understand there is some limitation to HBoot version, but I am unable to figure out how to update it to latest version. I would like to update my device from Android Kitkat to Marshmallow or some custom ROM which doesn't have a demo app.
P.S: A noob!
Update:
After reading lots of threads, I finally bought Sunshine license and activated S-OFF, now, I am with SuperCID 11111111 on my demo unit. Now, I want know about which Custom ROM I can run, and how can I update my Hboot to latest version?

You can use this ROM
https://forum.xda-developers.com/htc-one-m8/development/rom-resurrection-remix-v5-8-0-t3507210
Follow the directions there and you will be all right.

Might help, if you tell us what error message TWRP gives you.
Hboot version is too old to flash most ROMs. Also, such an old hboot version, is not compatible with many TWRP versions (might be the reason zip won't flash in TWRP).
What TWRP version?
Do fastboot getvar all, and post the result (delete IMEI and serial number before posting).
I believe @ckpv5 knows some about how to get the demo versions working or modded. The demo versions pops up infrequently enough, I can't remember the exact details.

He says TWRP gives an error flashing zips. So how is he supposed to install that ROM?
Most likely, his Hboot version is too old to support that ROM.

Yes, Hboot version is too old. I had a long fight with getting it restored. I had to try every other TWRP version and suddenly TWRP 2.8.0.0 worked for me!

Problem I face:
- Current TWRP is old, I am unable to make most out of it. (v2.8.0.0)
- Hboot is like hanging in stone age, I need to update it - but I have a demo unit (it comes with annoying demo app!)
- I want to run Custom ROM or at least a newer Android version.

You should be able to disable the demo app, using the "alternative method" indicated in the following post: https://forum.xda-developers.com/showpost.php?p=59735868&postcount=10
You can update to a newer version using the RUU and instructions on the following post. You will need to relock the bootloader in order to RUU: https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Be aware that RUU will wipe all data on the phone! Again, you will need to disable the demo app if you intend to stay on the Marshmallow "stock" ROM.
Updating to newer version (Marshmallow) by RUU, will also update the hboot, and other firmware (radio, WiFi, etc.). So after that you should be able to use the current version TWRP (3.1) and the current custom ROMs. Again, I'm not 100% knowledgeable on the demo model. But I don't see how the demo version CID (which is what triggers the demo app) would prevent you from doing the above. Especially if you disable the demo app, or flash a custom ROM (non-Sense) that doesn't have the demo app to begin with.

Thanks @redpoint73 for the help. Here is an update:
I finally able to get rid of demo app using SuperCID - means, now I have S-OFF device. I used Sunshine apk. Now I would like to update my device to latest Android (Marshmallow) - so should I follow the instructions on the thread you pointed me or is there something else I can try instead of locking the bootloader again?

1. No need to relock bootloader as you already S-Off your device
2. You got error because you don't use htc_fastboot as in the instructions.

Lots of love man! I finally got it. It worked like a charm through HTC_fastboot.exe. I was on macOS earlier and tried flashing ruu.zip through it, but after your message. I tried on Windows with HTC fastboot and wow!
I did a small mess and eventually relocked my bootloader! No issues with that, I can re-unlock it!
Thanks @ckpv5 for the final tip, and lots of love for @redpoint73 for pointing me at right direction!

Honest mistake. Relocking the bootloader is mandatory to run an RUU with s-on. So it's easy to miss the fact that the requirement (to relock the bootloader to RUU) is bypassed with s-off.
As you said, you can always unlock the bootloader again, if you want to install custom recovery, root, flash custom ROM, etc. Alternately, if you want to stay stock with no root, you can just leave it relocked.

You're very welcome. I wasn't sure if you wanted to pay for sunshine, so that is why I was suggesting some possible solutions with s-on. But glad to have pointed you in the right direction, regardless.

That is a very open-ended and subjective question. It's completely up to your preference, if you want to do any more mods. You can try custom ROMs, root, custom kernels, and much more. There really isn't much limit on what you can try.
