[HELP THREAD] HTC One M8 - Ask any questions here!

So you came to find help with your HTC One M8?Well, this is your thread!
I was surprised to see that a help thread hadn't been created in this forum yet (especially considering it's usually one of the first threads created in a device forum). Due to that, I thought it would be a good idea to set this up
Hello new user and welcome to XDA-Developers. We are a developer’s forum, with the purpose of development. Our work can be used in several ways, and, we know that sometimes it could help you. So, in order to maintain our forums clean and properly organized, maintaining a proper development environment while at the same time to give you a chance to join our forums, we created this thread.

This is a thread to behave in a tolerant way, taking into consideration that the user posting queries might have never even heard words such as “adb” or “ROM", so, if you are not willing to be helpful, I kindly invite you to browse into another thread.
Before asking a question in this thread, I suggest reading through the HTC One M8 Frequently Asked Questions as it's possible that your question may have already been answered in that thread

SIM card and IMEI issues after converting to GPE
Hello everyone!
So I just bought an asian HTC one M8 developer edition from a friend and I wish I couldnt be more happy, but Im facing some issues and I hope you could help me!
I converted my HTC dev to a GPE by flashing the RUU. Before that my SIM card and network worked just fine.
But now my baseband, network, IMEI etc are all shown by "unknown" and dont work.
I actually found a forum where someone had virtually the same issue: http://forum.xda-developers.com/general/help/urgent-help-required-htc-one-m8-sim-t2810468
But while he was able to fix it by flashing a radio image of his device's original CID, that same image doesnt appear to be available anymore! (i have the same original CID as the case mentioned).
http://forum.xda-developers.com/showthread.php?t=2736921
Right now I have super CID (11111111) and my radio shows up as 1.14.21331931.LA02_2G
my original CID was BS_US002
Does anybody knows if i have to find and flash my orginal's CID radio image, or is there any other way around...
Please help me guys! xDD
thanks in advance

@rafael.trad From looking at the OP of the radio thread, there's a couple of files showing under BS_US002 (quoted below):
Developer Edition (BS_US002):

Have you tried either of those 2 yet to see if it'll fix your issue?

I have tried them. But those two files are actually the only ones I can't open.
When i click on any of them it opens a Dropbox page with an error (404), saying that the files are no longer there. =/

Hello guys. I've been googling around why I can't root or unlock boot loader on my HTC one model id 0P6B12000. BS_US001 from what I understand it's the at&t dev edition. I've tried everything from towel root to sunshine to HTC dev unlock. Nothing works. Root fails, sunshine reboots, HTC unlock token is successful but does not unlock. Fastboot oem unlock returns err. Any ideas? Am I missing something?

Yeah, I'm getting the same problem. Flashed the unlock token and I unlocked the bootloader, but when I reboot into fastboot, it still says it is locked.

HTC Sync Manager
Sorry if this has already been asked somewhere, but I couldn't find an answer.
I have ViperOne up and running on my phone. Since I loaded it, HTC Sync Manager canont see my phone. When I plug my phone in, Android File Transfer Tool opens.
I saw another thread where they said you have to turn off fast charging. That leads me to another potential issue. The guide for ViperOne says that option is under kernels. The only thing I have listed under kernels is "Apply Kernel Settings On Boot." I don't see any of the other options.

Htc one m8 without OS trying to install viper
Hey XDA'ers
few days ago I tried to reset my phone to stock settings and I had stock Rom and everything on except it was rooted and I had twrp on it.
I accidently wiped everything on my phone including the OS itself and thats what you call having a soft bricked phone i think
cause I can still turn in on and enter Bootloader and TWRP.
so I looked everywhere on the internet for the Stock Htc one m8 OS ROM and found nothing at all but lookalikes etc so I searched through some the ROMS and found viper. I have downloaded ViperOne and put it on my SDcard i dont know if im supposed to have S-off to use viper ? or if im supposed to have stock OS and apply Viper to that ? but after successful installation it Reboots and enters Bootloader instantly everythime i turn it on I used to have to turn phone on and hold power button plus volume up then down to enter bootloader but now it just goes straight into that. ive wiped all data chache everything except SDcard
many times and tried to reinstall viper after deleting everything again but with no luck
i have Ruu for my model but my pc doesnt recognize my phone and i have tried sideloading stock rom and GApps but my phone still boots into bootloader when i turn it on
i will apreciate it alot if any one could help me since i have no other phone and my Htc one m8 is pretty new
Thanks in advance

help
i created a thread already, but I dont think it's garnering much attention.....I wouldnt even know where to begin to search for what im searching for, so Ill ask here....I have an AT&T M8. i have the latest baseband (3.28.xxx.6).....everything up til this point was working fine. I had vanir up and running, but after downloading MaxiumusHD and the ota manual update. i wanted to try something different, so I booted into recovery and attempted to wipe everything when I started getting red error messages. Im using CT's latest (non-multiboot recovery). Ive seen these red errors before, so i attempted to flash MaximusHD but b4 it finished the aroma installation, it booted automatically into the htc white screen. Currently I am able to boot into bootloader, and I can bring up fastboot devices and see that my computer recognizes my device. Everytime Ive tried going into recovery to wipe, it autmoatically boots into the that white screen without finishing the wipe process....Im using Hasoon's all in one toolkit so i dont have a computer android sdk package......Does anyone have any idea what I did wrong, b/c I have literally flashed hundreds of roms in the past and never once had this red error message when trying to wipe data in preperation for a rom flash......Right now my phone is in bootloader mode, fastboot usb...

I'm not 100% sure on this, but someone might be able to back me up. ViperOne uses the existing ROM when it installs. I don't believe that ViperOne is a full base OS. I don't know enough about the backups to say if you can use the backup off another phone or not.
If you unlocked your phone, that means you registered with HTC as a developer. You could ask them for the bad OS. I'm not sure if they will give it to you or not. It's at least worth a shot.

Hello there..

Got a new HTC one M8 from Verizon. S off, unlocked, rooted. Everything was working fine until tonight. Did a nandroid backup then installed an Xposed module (advanced power menu) and things started getting funky. Android system ui started force closing so using TWRP attempted a system restore. After a few minutes the restore completed so hit the reboot button. An error message came up and said "appears that device is not rooted, slide button to restore root". Root restore failed, device rebooted and white screen with green HTC logo and powered by ANDROID on came up. Phone vibrates then stays on that screen indefinitely. When I powered off using power and vol up buttons, powers down then immediately reboots and white HTC screen comes up. Can't get it to do anything else. Tried Squabbi's HTC toolkit to send fastboot / ADB reboot commands but wouldn't work. Any suggestions would be appreciated.

Viper, like all other ROM's, is a complete OS on its own. Partitions are another story, but usually not relevant to the average flasher except for an occasional firmware update.

Hi guys,
I've had my M8 for a couple of weeks now, and I love it. I haven't even rooted the thing yet, which is very surprising for me!
One issue I have with my phone, is the music app by HTC is frozen when I launch it. It does not force close. I have tried wiping data and cache, to no avail. It may be unrelated, but my phone doesn't sound too great when plugged into my speakers - maybe the EQ is frozen also. Sounds very virtualized, like I'm in a massive hangar.
I'm on 4.4.3, EE in UK. Thank you!

Can someone Please help? I tried to flash custom ROM and erased everything. Only thing I can do now is get into boot loader and Flash recovery. Won't let me flash any custom ROMS. TWRP just aborts the install and won't install. CWM states that md5 file not found and then stops installing.

Can't install ROM or update

I hope that someone can help me with this problem. Sorry it is such a long post, but I thought it might help with diagnosis if I wrote it all down.
I have an HTC One X with Android 4.02. It was purchased from Optus. I followed the process on the HTC web site to root and unlock the phone. Since that time I have never been able to update automatically. I contacted both Optus and HTC and was told that this was because of the root and, more or less, “bad luck!” I’ve tried to manually update the zip file with CWM but just get an error message and abort update.
From time to time, the phone would lag badly and run slower and slower. The only way that I could fix it was to backup all the apps and data using Titanium backup; uninstall all the apps; and then re-install them. Afterwards, all would be fine again for several months. A couple of months ago, it began to happen again and I uninstalled/reinstalled, but this time it didn’t help. Finally, after trying to figure out what to do, I did a system reset and then reinstalled everything and everything worked fine except that one of my apps (one I use all the time!) now will not work at all.
I decided that this might be because I needed to update to a newer version of Android. Unfortunately, when I tried to install CM 10.2, the installation failed. I thought that this might be because the Bootloader was too old (v. 0.95) but I read that if it was an AOSP Rom that I wouldn’t need to update the bootloader. So, I tried to flash Xenon, but again no luck. I’ve scoured the forums, but can’t seem to find anything that matches this issue.
The phone is definitely rooted. I’ve previously installed new Roms on my old HTC Desire, so I’m pretty sure I’m doing it right. However, I’m by no means a particularly sophisticated user and quite often the discussion in the forums is a bit esoteric for me.
Do I need to update the bootloader? If I do, then do I need to unroot the phone first then update then re-root?
Any ideas would be appreciated.

Hi
Can you give some details of the phone? CID?, international version?, S-On or off?, etc?
In short i think it is a good idea to update to a more recent bootloader. Then get yourself on to a newer ROM.
You might also want to consider twrp (big) as a new recovery.
This forum has lots of info.
Also take a look at www.onexroot.com
Thanks

The CID is OPTUS001.
The phone was purchased in Australia from the Optus network - I'm guessing then, that is an international.
The phone is S-on. From what I was reading when I was figuring out how to find whether it was On or Off, it seems like it needs to be Off to install any new Rom. I'd that right?
THanks for your help.

You can flash ROMs with S-ON. I fact its good to leave it as S-ON in case you flash the wrong firmware. Saved my bacon a few times.
Even if you bought it through Optus doesn't necessarily mean an international. Ca you post a screen shot of the boot loader screen. That will tell us.
Also an you find the CID number? There's some apps that can give you the the number. It looks like HTC-xyz. This will help in finding the right firmware.
good luck.

Nope, link still doesn't work. Use the attachments button when replying to attached the screenshot.
If that still doesn't work then let me know what the first three lines are when you are in fastboot mode. (Hold Vol down and power until you enter fastboot). The reason i want this info is to confirm you have the international version of HOX. If the second line contains the words "Endeavoru" then you have the international version, and we can then find the right ROM and recovery for you to use.
Also this is the link to download Hboot 1.36 for OPTUS001. http://d-h.st/users/ClydeB1/?fld_id=8110. Download this and keep it handy.
I am assuming that your bootloader is unlocked. First line tells you this. Did you use the site http://www.htcdev.com/bootloader/? Do you still have the unlock token?

Here are the first 9 lines. Don't know why it doesn't work.

The unlock token usually arrives by email. Do you still have the email? If not go thru the process again and get the token. Then keep the token. You need it after you flash the firmware.zip (new HBOOT)
The question you might want to think about is what ROM are you planning to install? That suggests the custom recovery you need to install. For instance HOX international works well on Lollipop but you have to reformat the memory using twrp-big. A simple task that you can find on www.onexroot.com.
Once you answer the ROM question, the steps would be as follows. Instructions can be provided if needs be.
1. Flash custom recovery of your choice
2 Flash the firmware.zip (HBOOT)
3. Flash the ROM of your choise.
Or you can go down the path that Thant is suggesting. I did the Lollipop upgrade using Resurrection Remix ROM after doing steps 1 and 2.
Thanks

Step 1 must to be after step 2, because if he flash firmware after recovery will be with stock recovery and not be possible to flash rom with stock recovery and must to flash again custom recovery. But how I think he is not a good with android devices don't have good skil to flash the firmware by him self. I suggest to answare my question and then to see if we can find RUU

Thank you both. Sorry for the delay in responding. Family emergency and I've not had time. I'll follow up in a day or so.

Thanks. I'll try it and let you know.

I've tried running the RUU. When it asks me to verify the ROM image version I want to update, the "To:"version is the same as the "From:"version. They are both 1.28.980.11 Before I go ahead, is that correct? Shouldn't it be a different version of the ROM image?

GO and see if the RUU will finish if yes this is good if give you error we will see what will do.
Yes they are the same but if RUU finish you will be complete stock and then will update wia Wi-Fi stock rom to latest hboot. Don't forget to relock your bootloader
replay if rUU finish and dont forget to make nandroid backup when you install new rom after update to latest hboot for your carrier

Issues to install ANY rooted Android to HTC M9 3.35.401.32 successfully

Hi,
Is this just me or this model has some issues to install any Android successfully. I received HTC M9 couple of weeks ago. There is no data so I decided to try and gain root. This was done through HTC DEV portal successfully. It shows UNLOCKED and S-OFF. I had tried various recovery hima TWRP 3.0.2.0, 2.8.7.0, 3.1.0.0 and somehow stock os became broken. So I tried standard procedure to put 0PJAIMG.zip to SD which is picked up by standard recovery or installing rom from TWRP.
I tried at least 5 recovery variants and around 8-9 android roms (LineageOS 11.3, 11.4, a lot of variants of stock rom with name *.401.* and ViperOne).
I was able to install only ViperOne, but I need LineageOS or stock rom with root access for apps.
LineageOS validated successfully from any version of TWRP, but the installation lasts forever without progress (and phone is extremely hot!)
Stock rom shows corrupted zip from TWRP and doing standard process (0PJAIMG.zip) doesn't boot at all after restart (or phone is crashed and I need to do force power down)
Any advices guys? I may arrange the payment if this is allowed for help to not spend weeks on this. What is the secret here? - I'm for sure not experienced on Android, but have IT skills. Many thanks

Try a twrp less than 3.0.0.0 but higher than the 2.8 you used and supersu 2.65. My stuff is here: https://drive.google.com/folderview?id=0B4vTiHTBB629QmxGTkpyZWlCR28
I have the 401 wwe phone too. Check the md5 hashes of the files you have and make sure that they match on the download site.
The phone is picky about twrp and supersu for some reason..

Thanks for help. I have tried twrp-2.9.0.1-hima.img with Windows and Mac OS machines and got this error:
Failed to boot to recovery mode
Press volume up or down to back to menu
The flashing process said OKAY, but not able to boot this as you see

Try a newer twrp

Hello friends,
My HTC M9 is acting weird.It reboots endlessly whenever I connect to any Wi-Fi.There is no problem when
Wi-Fi is off.
Recently this problem has stretched to the mobile data connection also.Therefore now I can't use Wi-Fi and data so that the phone won't start rebooting.
Please help.

But this contradicts with previous reply. He suggest to use any version between 2.8 and 3.0.
It's very difficult to find TWRP 2.9 and for some reason these are not on twrp.me page so is this really right option?
By the way if I use any version of TWRP 3.0 or 3.1, LineageOS doesn't boot and any HTC stock image says corrupted zip

Twrp has corresponding versions to the phones firmware.
2.8.7.0, 2.9.0.1 and 3.0.0.0 should ALL work with marshmallow. Higher twrp versions for nougat and lower versions for lollipop.
2.9.0.1 was pulled for allegedly being faulty but I have had ZERO issues in 2 years.
The same applies for supersu. 2.65 matches marshmallow.
I don't know if it's intentionally worked that way but that's the way it is.
If you tried twrp 2.9.0.1 AND supersu 2.65 and it still won't boot then you will be best sending it to a repair shop or back to htc.
Beamed in by telepathy.

Thanks for this. Just to confirm, I should do fastboot flash recovery twrp-2.9.0.1-hima.img (using fastboot provided by HTC or your Google share), power down phone when 100% completed, unplug the cable and boot recovery.
The phone says that it's RELOCKED and S-OFF. Is this ok?
How to install SuperSU? Is this only through TWRP - Install option? Or somehow I can do this through fastboot at the same time when doing TWRP?
So if everything is done correctly and no luck, only HTC can revert the phone to standard stock rom without root?

Any solutions or are there any people who has the same version of M9 and successfully using this? At least can you confirm that it works for you. Many thanks

This is just for other people. If you have the same version of M9, be careful with rooting. I'm able to install various TWRP or original recovery, but not able to install suggested TWRP version and importantly any stock rom or LineageOS so the phone is useless. I still cannot use this

In regard to your first post: Did you set the phone S-OFF or did you buy it in that state? (HTCdev doesn't set you phone S-OFF. It only unlocks your bootloader.) If you bought it second hand then the previous owner might have screwed the phone. That would explain why your phone didn't boot after you successfully flashed a RUU (which isn't meant to be flashed via TWRP, btw).
In regard to your last posts: If your bootloader is re-locked then the phone won't boot as long as the phone isn't completely stock. And as soons as you install TWRP your phone doesn't fulfill this requirement anymore.

Thanks for your post. I bought used phone in S-OFF state. If any suggestions what I can still try to do by myself that would be appreciated as well.

Re-unlock the bootloader. As long as TWRP is installed your phone won't boot, otherwise.

You're in this predicament because you didn't follow directions. Henceforth, follow directions precisely and if you're unclear, then ask specific questions about those instructions.
IIRC, Nougat RUU won't flash with S-On but you can try it and then see if it takes the OTA to Oreo.
Can you unlock the bootloader? (I don't know if you can just flash the same file you originally used or if you have to get a new one after relocking.) If you can do that, you should be able to install TWRP and flash any of the custom ROMs (LeeDroid for a stock-based ROM).

Okay thanks , im gonna try this , but i dont think that i can flash ruu without stock recovery
and i also cant lock the bootloader cause it needs to enable (oem unlocking) from developer settings and i have no system to do that and i dont know how to do it from fastboot
i tried many times to flash twrp nut i dont think with relocked bootloader and s-on

You dont NEED RUU. OTA is enough!
Try this. Download this OTA which is for your device
https://androidfilehost.com/?fid=890129502657577036 > remember to refresh link as sometimes androidhostfile shows as not found or error

rename it to 2PS6IMG.zip
(make sure its not 2PS6IMG.zip.zip again. show extension in windows to make sure)
put into the root of your SDCARD (transfer via microSD card reader)
put SDCARD back into your phone
boot phone in download mode (volume down + power) let go of power but keep holding volume down for a while
once in download mode the 2PS6IMG.zip will get detected and you can proceed to install by pressing volume up.
YES IT DOESNT MATTER IF UR BOOTLOADER IS LOCKED AND S-ON or EVEN IF RECOVERY IS MESSED UP. As long as CID matches (i assume it will since yours is .401 variant as per your bootloader info "version-main: 3.16.401.2" which is unbranded cid / europe /mid.east/africa the link i gave should work)
i screwed up my htc 10 but it got rescued too because of this

Just to enlighten you all, the OP says he formatted everything, all the partitions including the system. So there is no OS present on the phone.
In this case a RUU is much better because it also holds the full stock system. The OTA does not contain the full OS. So flashing the OTA on a phone without the OS present is not going to help. The phone will not boot.
All this info is because i had a good read in the OP post. The theory of the OTA is fine but not in this case.
So before you guys will wave your precious little genitals towards me i suggest to read more carefully and base your help on that
Cheers.

Yeah thanks. I deleted all my post because there's no point in arguing. Your correct I totally forgot what the OP problem was after all this. Thanks for the clarification.

Hi Mr Hofs,
Thanks for the enlightenment.
In my case I had erased the OS also. Not only that. I had erased system. Last time I had access to TWRP it kept giving me unable to mount several partitions. After which I lost access to TWRP. The bootloader did not allow me to enter any recovery after that. It just kept rebooting to download mode. Much less I had no OS that would load. Luckily I did not relock bootloader and it was left unlocked. With my past experience with my several HTC devices I know for sure that a major OTA such as this OREO OTA has the ability to completely rewrite the whole system and restore the device to working. I have repeated the scenario and even posted pictures in the post above. You can clearly see the system image is being installed in one of the pictures. So with much respect I really disagree with the whole OTA is not gonna work in this case concept. Because for me I have proof of concept. ?
I stressed several times in this post that it has worked for me. That in my case I had access to download mode and that I used the sdcard method. Download detected the OTA renamed as 2PS6IMG.zip and my phone got fully restored HTC 10 to working condition.
As per my experience as mentioned above HTC phones like many other are designed to pickup "correct" types of installable and device matching zip files from sdcard no matter what the situation is and would try to restore the lost functionality to ensure a device can be used again.
I just hope OP gets his device recovered. Because the OTA link I have provided OP is the same I used. It contains OS and everything vital. Just the OP needs to try. Unless he has a mismatching CID I assume it will work for him too.
Thanks ?
Thanks to XDA community as well.
This would be my last post in this thread unless OP requests my intervention. Speaking of which I wonder where he is when so much has been said. Haha.

It's great it worked for you and i truly hope it helps the OP too. The other weird thing that notices me actually is that in fact the OTA is in this case the same as the RUU ? Why isn't there a 3.16.401 RUU ? I think there are some hiccups when the OTA is refferenced as a RUU (which feels like it is in this thread because it seems to contain the OS and firmware)

Yeah everyone I flash RUU it does bypass some things. Relocking bootloader usually causes problems and I don't know people still keep doing it. I would say flash twrp followed by leedroid but pretty sure you need an unlocked bootloader to flash twrp. Sorry but I'm out of ideas.

Installing the original OS with SD card or autoload

Dear friendly xda-developer people,
my HTC One M8 went out because of an empty battery. When I restarted, it only boots the bootloader. The security mode isn't working as well. I tried all I could think of and now I just want to install the original OS on the phone in hope that it will work again.
When I boot up the phone it says it is "OS-6.12.161.4". I am from Germany and I guess it is a vodafone branded HTC. So I do not find the right software on the official US website. I tried to google a different version and all I could find was a software to which the phone anwsers when I try to install the .zip via SD-card "Image Update Fail! Device halted due to Large Image update fail!"
I will post the complete screen of the boot below.
Any ideas what I could do? I tried to update it via PC, that didn't work as well. I think I need the right software and the one I found might just be the wrong one. I also tried to unlock it, but relocked it because I read, that I can not install the original software if it is unlocked.
If I can not install the original os: Is it possible to install something else that just works like the original OS? I can not use Google Products than?
I am really thankful for any advice.
Greetings

What is the background of this device? Did it have a stock "official" HTC ROM on there when you had the "no OS" issue? Was it ever bootloader unlocked before you unlocked it to try to solve this problem?
Best for us to see more details about the phone. Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

You absolutely need to use an RUU (ROM Update Utility) that is intended for your M8 version's (Vodaphone) carrier ID (CID) as well as the version number 6.12.161.4. Another version number means it is made for a different CID, and will fail by definition. HTC phones are quite strict about version number checking.
In your case, I don't think that there exists an RUU for the Vodaphone version. But you can install the stock OS by other means (see below).

While your Vodaphone version M8 doesn't have an RUU, there is another way to get back to the stock ROM. You can unlock the bootloader again, than install TWRP and a stock TWRP backup from the collection.
https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Only need to do through Step 9, then reboot and it should boot to the OS. The remaining steps were only for getting official OTA updates (which is no longer relevant).

I think you mean a ROM straight from Google? Google doesn't make complete ROMs for any device, except for Pixel devices (and the old Nexus devices). For any other device manufacturer, at least some part of the ROM needs to be customized for the specific hardware configuration. But you do have some options, if you want a ROM that is more lightweight then the HTC Sense interface:
Even though we don't have a "pure" Google ROM; what we do have for the M8, is something called the Google Play Edition (GPe). Which even though made by HTC, is designed to feel like a "pure Google" ROM. Once you have the bootloader unlocked and TWRP installed, you can install this the same way as a custom ROM. Follow the part of the thread labelled "Flashable GPe ROM". You can't flash as an RUU, since you are s-on.

Another option is Lineage custom ROM. Lineage custom ROM is somewhat similar to a Google OS. Although at this point, it does have enough modifications, that I can't really consider it a "pure Google" experience. But it is much more lightweight than a Sense ROM. Very similar to installing the GPe ROM, once you have the bootloader unlocked, install TWRP and flash the ROM.

What is the background of this device? Did it have a stock "official" HTC ROM on there when you had the "no OS" issue? Was it ever bootloader unlocked before you unlocked it to try to solve this problem?
Best for us to see more details about the phone. Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
You absolutely need to use an RUU (ROM Update Utility) that is intended for your M8 version's (Vodaphone) carrier ID (CID) as well as the version number 6.12.161.4. Another version number means it is made for a different CID, and will fail by definition. HTC phones are quite strict about version number checking.
In your case, I don't think that there exists an RUU for the Vodaphone version. But you can install the stock OS by other means (see below).
While your Vodaphone version M8 doesn't have an RUU, there is another way to get back to the stock ROM. You can unlock the bootloader again, than install TWRP and a stock TWRP backup from the collection.

Only need to do through Step 9, then reboot and it should boot to the OS. The remaining steps were only for getting official OTA updates (which is no longer relevant).
I think you mean a ROM straight from Google? Google doesn't make complete ROMs for any device, except for Pixel devices (and the old Nexus devices). For any other device manufacturer, at least some part of the ROM needs to be customized for the specific hardware configuration. But you do have some options, if you want a ROM that is more lightweight then the HTC Sense interface:

First of all: Thank you very very much for your time and effort answering me. I highly appreciate that.
I will try to deliver fastboot getvar-data as soon as I am able to get back to a Windows or Ubuntu PC.
I now was able to install a TWRP backup. Your link is very helpful.
Sadly, my sound isn't working anymore now. I guess every 20 reboots or so it does work, but I can not replicate that.
Also I can not make videos and can not record audio. I then tried to install Cynagenmod which had the same problem and then I tried Lineage OS which had the same problem as well.
Do you have an idea what I can do to fix that? I read about upgrading radio, but that sounds like an easy-to-brick-my-phone way.
In case that helps: Background of the phone is just stock "official" HTC ROM as far as I know.
Since I was able to install other OS, the part of the screenshot above where you can read "OS-6.12.161.4" is just "OS" and nothing else anymore.
Regarding the topic that I wanted the original firmware: I thought Gapps are only available on official firmware. Since I know that a custom OS can run them as well, I do not care about the OS. I thought LineageOS and Cynagenmod were both lovely and would try out everything that does the job.
Any idea how it is possible that the sound / recording videos and sound don't work with three different OS?
Greetings

Might be a firmware issue. When I say "firmware", I am referring to a specific package (usually a file named firmware.zip) that contains certain partitions necessary for the ROM to work (radio, hboot, recovery, and others), but does actually not contain the ROM itself. On that note, it is probably best for you to stop thinking of the term "firmware" as interchangeable with the ROM. If you mean ROM, just say ROM. No need to call it something else, and doing so will just cause confusion. It is best to use specific terms (stock ROM, RUU, stock TWRP backup, etc.).
Random sound or video issues can sometimes be a result of old/damaged firmware. It is probably useful to flash the firmware (more on this below).

You can't flash a radio (alone) with s-on. And not worth getting s-off ($25 US by sunshine app) just to flash a radio. What you can do, is flash the whole firmware zip, and see if that helps. But I'd like to get the full getvar output, to make sure which firmware is the correct one for your version M8. As you mentioned, flashing the wrong radio can be catastrophic.

What version TWRP did you install? If you followed the guide closely, you should have used TWRP 2.8.7 or later. No number being shown for OS version is sometimes a result of flashing Lineage (known bug), or an old version of TWRP.

The first time I tried working with TWRP I installed an older version - sadly don't remember which one. I installed a version of Cynagenmod with it. Then I accidentally crashed TWRP somehow so I had to install it again so I am using 3.3.0-0 right now because I thought it's best to install the newest version I could find.
Should I try again installing a different version of TWRP?
Sidenote: I now have the problem that WLAN doesn't work a lot of times. I need to reboot around 5 times so WLAN works. I guess that is another issue because of the mistakes I made while installing different OS.
Thanks again for your time.

TWRP 3.3.0-0 should be okay. I agree, using the latest version is typically the best thing to do.
What I would try, is the following. Note that you will lose all data on the phone when you do this, so plan accordingly, if there is any data on the phone you want to keep (backup to cloud, computer, etc.):
1) Flash the firmware fw_6.12.161.4 from here (instruction on how to flash firmware, near the bottom of the post): https://forum.xda-developers.com/showpost.php?p=60218734&postcount=5
2) After flashing firmware, you will need to unlock the bootloader again. Either use the same unlock bin code you used before (flash with fastboot command). Or go through the process on HTVDev.com, to get a new code.
3) Flash TWRP back to the device (flashing stock firmware wipes TWRP, so you need to put it on there again).
4) Restore stock TWRP backup 6.12.161.4, using TWRP. https://forum.xda-developers.com/showpost.php?p=60211240&postcount=3
Not sure if this will solve your problems, but I'm hoping it will. This process will put a stock ROM and corresponding firmware on the device (a clean slate, as it were).

Dear friend,
I followed your guide and right now I am at step 3)
While looking for the newstest TWRP.img-file the phone is booting Android and is installing Apps right now. I even heard at startup sound. Is it possible, that I won't need the following steps and it just got the stock firmware from my last install?

Yes, it is possible you don't need to do anything further.
As I warned before, be careful about using the term "firmware". It seems you are using it synonymously with "ROM" again. If you accomplished Step 1 (as designated in my last response) you flashed the stock firmware. The stock ROM should still be there from the TWRP backup you restored previously. Nothing you have done so far, would have overwritten the stock ROM that you restored, so it is still there.
You previously restored the proper number 6.12.161.4 stock TWRP backup?

Yes, I did and it all works fine now. Even the battery is much better than before.
Thank you very very much for your time and help. If you ever come to Germany, let me know and I will buy you a drink or something
Kind regards and have a good life
