I providing as much information as i can (and think you need) for your help.
My HTC M8 when I bought it new from the store it came with lollipop on the 02uk network, I then got the official update to marshmallow. I was quite happy with this but needed an app that required root.
So I unlocked my bootloader, downloaded openrecovery-twrp-2.8.5.0-m8 and installed SuperSU via the recovery. But something went wrong, when I rebooted there was no OS installed, I must have accidentally deleted it. But I hadn’t made a nandroid backup at this point.
Since then I have been trying to get back to stock. I research and looked around the only way I can flash marshmallow is if I go further and pay for S-Off.
So my plan was to Install back to stock Lollipop then get the upgrade again to marshmallow.
Even this proved to be difficult. And is where I could use some advice.
My CID is HTC 02__001 So I found the Nandroid collection on XDA and downloaded
1.54.206.5 - TWRP
1.12.206.17 – TWRP
The latest updates for these seem to be very old (not Lollipop) but I gave it a shot installed the roms, the recovery and locked the bootloader. Then went to upgrade all the way to where I was. Unfortunately, after so many updates the WIFI stopped working and I was unable to upgrade further., ad the only way of repairing was reflashing the rom.
In the settings, I noticed my build number was 4.16.401.13 and remember seeing this version in the collection
So used the stock recovery from that and flashed the rom, then locked the bootloader.
The 4.16 is the international version CID__001 while this got me straight to lollipop I don't have the original bootup screen with the 02 animation. And when I go into the updates there is only 3 security updates not marshmallow.
I did attempt to download and flash OTA Marshmallow when i done this from
http://www.htc.com/us/support/htc-one-m8/news/
but kept running into errors with the bootloader signiture check, I then realised its because I needed S-Off
So at the moment I am on 4.16 international, I have unlocked the bootloader and running TWRP recovery until I can figure this out.
Would I be right in thinking I cannot use 1.54 recovery with 4.16 rom as a restore?
Or are there files that I have overlooked for 02uk lollipop stock rom and recovery?
Also if needed my baseband version 1.29
This thread is no longer needed, After extensive searching and looking at loads of different sites and options I found http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Which was able to help me fully restore.

Thank you guys in advance for your help but I just had a few questions. I am running 4.4.2 currently with the stock rom rooted and unlocked bootloader. I have however issued a few Mods such as extreme power saving and built in tether. Can I just load the 4.4.4 firmware and radios, switch back to stock recovery and take the OTA to 4.4.4 without having to wipe anything or since I have used some mods do I now have to wipe my device and put everything back after getting the 4.4.4 update. The reason I ask is I like having the stock features while just using google now launcher on top of sense. Also would any of you have a recommendation on a ROM to achieve this same thing so I dont have to go through this everytime I want to take the newest OTA if it is not possible to take without wiping.

Flash the ruu here. That will get you to 4.4.3 the easy way and make you 100% stock so you can take the ruu. Then flash twrp and flash su or the rooted Rom of your choosing.
The RUU is one way to go, although I would never update via OTA...
Another would be to flash the firmware and radios from here:
http://forum.xda-developers.com/showthread.php?t=2723159
And then Scott's rooted stock rom from here:
http://forum.xda-developers.com/showthread.php?t=2914922
He usually has them up a few hours after a new OTA has been released. Even better - try his stock, debloated CleanROM once it's out.
This way you can keep your recovery. You can even try to just flash the 4.4.4 firmware and radios and see if it runs your current 4.2 ROM ok. But I would not update the rom from version to version without a wipe.
The setup is the price to pay for getting a new and hopefully better Android version.
Hi,
I have a UK Moto G (2013) running 4.4.4 KitKat and I installed CWM recovery and rooted it some time ago. Now they are pushing out Lollipop OTA I am getting nagged by the phone to update - but, it always fails when I try. Presumably this will be because of the CWM and/or root. I tried a full unroot but that didn't help as CWM kept complaining on the upgrade reboot about something (can't remember what now!). I've read that in order to get the OTA update to work, I have to get the phone completely back to stock, but I can't find a working stock recovery for it. Do I have to take it back to stock or not ? Either way, would anyone know how I can get the OTA update to work please ?
I've tried flashing a couple of stock recoveries, but one fails to flash at all and the other doesn't work - you choose recovery and it just reboots the phone.
At the moment it's back to rooted, unlocked bootloader and CWM recovery.
Any help you could offer would be very gratefully received.
Thanks!
Are you able to locate the phone's from here: http://www.filefactory.com/folder/c6cdedc45a775d27/?sort=filename&order=ASC&show=100&page=1
Hello,
I have a rooted Verizon HTC One M8 running on Android 4.4.2. I do not have the stock recovery and for some reason I am unable to flash CWM, so I am stuck with TWRP. I keep receiving notifications that Lollipop is available to install, but it fails each time I try to install it because I am rooted. How can I unroot and get back to my stock ROM so that I can install the update?
No need to update via OTA. Just follow the instructions here and you'll be on rooted 5.0.1 stock

Questions
Thank you for the reply. Are you 100% sure this is compatible/will work with my phone? If I flash the ROM and it doesn't work, can I simply flash a backup image I made to recover? And when I flash the ROM, will I lose all the data on my phone? Also, where may I download my stock recovery? I searched all over the internet and couldn't find one for the Verizon version of the HTC One M8.
Thank you
That RUU is a complete stock firmware package, including the recovery. Read the OP.
But if you're just looking for the stock recovery you can find it here: http://forum.xda-developers.com/showthread.php?p=52017763
That alone won't let you take the OTA though. If you modified your stock rom the OTA will fail.
You can find a complete stock rom elsewhere here on XDA, but why the trouble if you have it all in one neat package with the RUU?
Thank you very much for the help and useful information.
Sorry to bother you with all the questions but I have one more. How do I make a backup of my stock recovery? Say I went out and bought a new phone, how would I backup that stock recovery?

Hey guys, I'm pretty much a noob at rooting and unlocking. Up until I rooted my nexus 5 in the hopes to get side by side apps I haven't rooted since my gs2. Anyways I rooted my phone via the nexus 5 root toolkit and unlocked the bootloader and whatnot. I found out that I couldn't do side by side because it wasn't available for my version of android. I attempted to unroot and return to stock and I just unrooted and locked the bootloader. I'm a total noob at this and have googled for hours and can't figure out how to return my phone to stock without twrp. Everytime I try to do OTA updates it just restarts to twrp and it's super annoying. Can anyone give me a for dummies walkthrough of how to get back to stock so I can do OTA updates?
I think (people will correct me if I'm wrong) that in order to get back to full stock, including stock recovery, you will have to do a flash of the stock ROM which will install everything including recovery. Maybe there's an image of the stock recovery available which you could flash into the recovery partition to overwrite TWRP - I've never thought of looking, but Google is your friend...
Yea just fastboot the stock img files there's plenty of fastboot guides around and it's stupidly easy to do
Hi there !
I have U11 2.31.400 version
-Bootloader Unlocked
-TWRP installed
- Root with Masgik
Now i want get OTA update
-First, NO RUU, i tried Restore NANDoid backup and Flash stock recovery (same version)
(https://docs.google.com/spreadsheets/d/15JL3tRWDSVOUKo_revEYtQ_tRcOSJ0vWcvk8a7TK8Hk/edit#gid=1564536856)
-> Not work
-I tried flash stock Firmware ( got 35_RU_Partition_not_support firmware error)
Anyone can tell me how to got OTA with out RUU??
Hi there
I think we're in the same situation.
I also unlocked my phone, installed TWRP and Magisk on stock system and did a NANDroid Backup before doing so.
In order to get the OTA I restored stock recovery (which i had to extract from OTA, since i forgot to back it up) and started OTA.
--> Red Triangle!
Even after restoring stock NANDroid the OTA wouldn't install.
My mistake i think was that i didn't kept the stock system read only when i did the backup in twrp and swiped to allow modifications.
According to some threads here, even mounting the system r/w would break OTA functionality.
So since i also have no RUU for my device, i don't have the chance either to go back to stock. Maybe you did that mistake too.
The only way i can think of now, is to go temporary S-OFF, change CID and MID (to 401 international for example), flash Firmware and run the RUU for it.
But i'm not sure it'll still work after flashing the firmware.
Can anyone maybe confirm this way would work?
Thanks
Edit: Hi, in case you're still having this problem, here's a solution:
