[Q] Broken recovery HTC M8 (Devil's Loop)

Hei guys I managed to **** up my HTC M8 pretty bad (I think..)
I had a rooted M8 with 4.4.4 so 5.0.2 came out a few days ago and I tried to update my phone today. To do so I wanted to unroot my phone so I did the following things:
1. I did a factory reset using the option in Clockworkmod
2. I flashed the stock recovery to my phone
3. I (re)locked my bootloader
The problem is something seems to be wrong with the flashed recovery, Factory Resetting or booting into recovery just restarts the phone and the OTA also just reboots the phone. Unlocking the bootloader and CHECK SMARTSD also won't work anymore..
I really don't know what to do now/where to ask for help..
Here is some information I can provide:
Bootloader looks like this:
*** Software status: Modified ***
*** Relocked ***

Getvar All (Toolkit) gives me this:

Hope you can help me, thanks for reading.

Unrooting and relocking the bootloader was a useless move. OTA accepts rooted phones and with bootloader unlocked. OTA needs a stock recovery and a clean system.
What you can do is flash via adb TWRP and restore a working backup of your firmware.
P.S. Delete your IMEI and SERIAL NUMBER from your post.

HTC M8 Help needed to return for warranty repair

Hi Everyone,
Although I've been using this site for a long time to get information, this is my first post and I really hope I am posting in the right place! I have searched desperately for a way to do this myself but I've been unsuccessful and am now asking for help
Basically, I have a fault with the touch screen on my device and it's still covered under warranty. There are different HTC repair centers here in Ireland. I returned my HTC to one of them and it was sent back to me because it's modified. So to cut a long story short - I really want to get back to a stock rom, unroot and re-lock bootloader and send it back to the other company in hope I can have it repaired. I really have tried very hard to figure this out myself and I'm completely lost so I really hope one of you good people can help me out.
I'll try to provide as much information as possible.
I own a HTC One M8 (International Unlocked)
Bootloader Unlocked via the HTCDev Website
Kept S-ON and flashed LeeDroid ROM
All I want to do is get it back to the way it was before I messed with it.
Hopefully I've provided all the details you'll need but if you need anything else please ask me and thank you so so much for helping me!!
Allan!

Search xda and google for M8 return to stock. This should be the right ruu for your cid: https://www.androidfilehost.com/?fid=95916177934518148
You will probably need to be s-off in order to run the ruu and lock the boot loader without it showing relocked. You may need to relock the boot loader for the ruu to run also. You really need to read as much as possible about returning to stock.

First of all, please delete your IMEI and serial numbers from the top post. These are private data, and should never be posted online (and no necessary for us to help you).
You have a couple major issues causing problems with custom ROMs:
1) Main version 3.30.651 tells us you are still on KitKat firmware (hboot, radio, etc.). You should update to Marshmallow firmware (6.20.651) using the following thread: http://forum.xda-developers.com/showthread.php?t=2729173
2) You have the Sprint version of the M8, which uses a different kernel from the other M8 versions. You should only flash custom ROMs from the Sprint Dev Section here, or there are also several ROMs in the "international" M8 section that support multiple versions including Sprint (but it will explicitly state Sprint support in the ROM thread).
ROMs that do not specifically support Sprint will fail to boot.
CM uses its own kernel, and probably supports multiple M8 versions for that reason. So that is why CM12.2 flashes and works properly for you.

Device stuck in fastboot

Hey guys
like described in the thread title, i need a little help here, i got a HTC one M8, thats stock in fastboot.
it will not bootup to anything else than fastboot and RUU. no custom recovery is working or any rom.
i have read multiple threads by now and look 3 days and i can't find the right RUU for the device at all.
If someone could point me in the right direction here i would be grateful

and ofc. a screenshot of the bootloader
for the steps to do here:
since device is S-ON, i need to relock the bootloader with fastboot oem lock
using the HTC_fastboot.exe with command prompt to get the device into RUU mode and after that flashing the correct RUU for it, after renaming the .zip itself to RUU.zip, right?
or is there any other way to get the device back to stock or at least a custom recovery / root whatever to set the device S-OFF?
i know the topic was here multiple times, but since device isn't mine and i really don't know what exactly was done before with it, i need a helping hand here.
any fitting android version, 5.0.1 or 6.0 would be fine, since the device will get root and later on S-OFF and a custom recovery and another nougat based android version.
as long as i can boot up with root, i would appreciate every help here.
Cheers
Mike

1. This device is not M8 but M8s.
2. There is no way to S-Off this device currently. Not supported by Sunshine.
3. There is no Nougat rom for M8s, only Marshmallow as current latest.
4. You shouldn't relock bootloader before you have a correct RUU in hand.
5. I know a lower RUU version is available for free but won't work on your device due to S-On
6. No same version but higher version 2.11.161.1 is available but will cost money
7. If you can unlock bootloader then you can restore 1.11.161.10 twrp backup and then OTA to current version 1.21.161.1 and OTA up to the latest.

[Help Req] HTC Desire 820 A51_UL Single SIM

Hi!
I was messing around with the S-ON and I think I blew my phone up.
I can install TWRP. I think I got every possible ROM and RUU's right now because I tried 20+ combinations. There is no OS right now. Just plain old HTC white screen. I can't fuzz with fastboot flash zip because S-ON is there and I couldn't find any way to S-OFF without atleast a booting system and HBOOT 3.19.
How can I fix this? I was using 4.4.4 stock rom before I messed this up but I tried to install so many ROMs and stuff that I think that doesn't matter anymore.
There is a red OS-1.21.401.1 (2.10.401.2) text in bootloader screen which wasn't there before I tried to push some ROMs. Also, Revolution S-OFF doesn't support HBOOT 3.19. From now on, we can call it soft-bricked :/
Any help is appreciated. Please carefully examine my bootloader vars before making any comments.
Thanks a lot!

I'm still struggling... I'm open for advices

Solved it by myself.
Using this ROM 0PFJIMG_A51_UL_K44_DESIRE_SENSE60_HTC_EUROPE_1.29.401.5_RADIO_01.01.010_U10305041_08.01.41222_2_RELEASE_449952_COMBINED_SIGNED.ZIP
Wipe everything, flash stock recovery, put this rom on sd and fix it. I was on Kitkat 4.4.4.
Case closed.
