You need to put the stock recovery back for the OTA update, then put TWRP back to root the install.
Yup need stock recovery easiest way is to flash the stock backup do the ota then flash twrp and root once on lollipop, make sure you use beta 2.44 superuser zip

Hi,
So I have a GSM HTC One M8 that is rooted and running a custom rom and recovery.
Due to the 4.4.3 update, I need to update my firmware. From what I have read in the forums, I first had to go back to the stock rom and recovery. Which I did. The nandroid back up process went fine, but the stock recovery wouldn't load up for me. And also, the stock rom is already at the latest 4.4.3!
When I tried to go to settings and check for updates, it says that I already have the latest version installed....
Few questions.
1. Do I need a stock recovery to be able to get the OTA update?
2. Is this the only way to update my firmware?
BTW, my device is S-ON and Unlocked.
I recently unlocked the bootloader of an HTC One (M8) running Kitkat, installed TWRP then flashed a .ZIP file to root the phone. Now Lollipop has been released there's an OTA available on the phone but I'm not able to update through it. I've seen different posts all over the place about how you have to just install the stock recovery or how you have to use an RUU or how you have to use a NANDroid backup so the opinions are quite conflicting.
I basically just want the phone to run the stock unrooted version of Android so I'm able to perform the official OTA updates to Lollipop so how do I go about this? Any help is greatly appreciated!

No need to unroot. You just need a stock recovery.

Let me try to clarify the confusion based on my experience with the Lollipop OTA update. First, you need to remember that, during the OTA update, the software checks for two things: 1) the version of the recovery; and 2) whether any system files has been modified (described in my earlier post).
As a result, you only need stock recovery (from 4.4.4 or 5.0.1) to initiate the OTA update (as mentioned by the other poster). If no system files were altered as a result of your root access, your OTA should finish without errors.
However, root itself and what people do after they have root access often mean some system files were altered. Hence, they need to use either RUU or TWRP backup to restore they all files back to the factory version.
Finally, as for RUU vs. TWRP:
The RUU or TWRP version must match that to your carrier version of M8. The RUU is the better option, but not available for all carrier versions. When RUU is not available, people rely on TWRP nandroid backup generated by other users.
Bottom line or my advice:
First do a TWRP backup before you start anything. If anything goes wrong, you can always revert back to the working status as it is now.
To begin, go back to stock recovery, and see if the OTA update will go through. If not, you will see red triangle. Then hold Vol + and tap power button once to see the error messages. See my post above. If you ran into the same error as I did, you'll know what to do (RUU or TWRP backup to return to stock).

A very well-worded answer
Hello!
I have a M8 **Dual Sim** variant (in Switzerland). At the time of purchase, only stock KitKat was available so I unlocked the bootloader, TWRPd and rooted and did what I needed.
Now I have a Lollipop upgrade available but it won't apply (downloads but sig check fails), presumably due to having unlocked the bootloader. I tried flashing (what I think is the original) stock recovery, relocking the bootloader but no good.
I also tried the stock KitKat RUU but that also fails to apply.
I would like to get the Lollipop upgrade *somehow*... should be possible but I didn't quite manage it yet. Please can someone advise?
Thanks.
After some hours, I solved this. Posting here for the benefit of others...
I found a DUGL-specific TWRP backup which I placed on the sdcard and attemped to restore from. It wasn't having it so then I found a dual-sim (DUGL) specific ROM with an older OS version (https://basketbuild.com/uploads/dev.../m8dugl_3.33.401.6_stock_rooted_odex_cptb.zip) so flashed the latest TWRP recovery, then this ROM. Then the OTA worked.
Finally a Lollipop build on HTC M8 Dual Sim!
Dear Bonstio
Thank you so much for your follow-up post.
Let me explain my story:
I have a Dual Sim HTC One M8.
It was rooted and running lollipop after an OTA update a couple of months ago. Bootloader was Unlocked and was S-ON.
Recently - i got the OTA Update that corrects stagefright. I took the update and installed it. I had the stock recovery installed in order to get and install OTA Updates.
For some reason, when i restarted after the OTA update - the phone was stuck on the HTC Splash screen. This went on for 5 to 6 hours.
I tried factory data reset, i tried TWRP as the recovery - but i was unable to get the phone back to boot into the OS.
I found a TWRP Backup online and installed that via TWRP. That brought me back to the stock Kitkat 4.4.1.
I then restored the stock recovery.
Looked for an OTA Update - found one for OTA_M8_DUGL_K444_SENSE60_MR_HTC_Europe_3.33.401.6-1.45.401.12_R_release_398692-1.zip .
Tried to apply the OTA update with stock recovery installed - the update would not install.
After many days of trying different way to install the OTA update - i gave up and settled with the the fact that i will never get Lollipop and i would be stuck on 4.4.1 forever. I tried several RUUs, stock recoveries, Zip files for TWRP, etc.
I then did a search and stumbled upon your post. I clicked on the link you have provided and installed the stock ROM as per the instructions listed here: http://htc-one.wonderhowto.com/how-...tc-one-for-completely-new-experience-0153231/
I now needed S-OFF to install this "New ROM".
I downloaded Sunshine S-OFF - paid the $25 and got S-OFF. I knew this had to be done before installing custom Roms.
Once i was S-OFF - i followed the instructions on the link above to install the file you have mentioned in your post. - it booted to an updated version of Kitkat - 4.4.4 .
From there - i looked for an OTA update - downloaded it. Chose "install later".
Went to the download folder and copied the update to my PC (just incase).
Then i installed the stock recovery 4.30.401.15_ds_recovery.img and rebooted. Once in the OS - i chose install update - the OTA update rebooted my phone and installed Lollipop on it.
So a BIG THANK YOU to you for posting your solution - it really helped me get back to Lollipop.
I have s-off my device and now I cant find the lollipop update for my device A5dug cid-HTCCN703 china Unicom version

If it's the Stagefright patch update for lollipop it's better you didn't find it before S off because I've read their having problems getting S off with this patch applied. If your talking about updating from kit Kat to lollipop it should still show in your phone as an OTA or in HTCsync when you hook your phone to your computer for backups. To update though either way you'll need to reflash your stock recovery and unroot. Luckily with S off I'm pretty sure you can leave your boot loader unlocked when flashing stock Rom unlike those with S on. HTCs site should have the stock zip for your model to download. We do in the U.S also. but it's in the RUU format. Then you just download the zip and flash it using ADB/fastboot but first you'll need to first find and flash your stock recovery I believe then unroot then flash stock zip.
thanks for repplying but it started to find updates again, guess it was maybe server issues or something

thank you.
i just want to upgrade to android 6.
i know that i can flash custom roms with custom recovery. is it possible for me to download an stock system image and flash it with custom recovery the same way? i do not want to make everything back to its original. i want a rooted android 6 with custom recovery.
-----------------
i had some search. if i upgrade to stock android, then i will have to root my phone again and for that i have to flash a custom recover again. i searched and find out that android revolution custom ROM is a good choice for ones how wants to keep HTC Sense.
thank you for your support.
Check here for possible stock system images and recoveries...
You should be able to flash a stock system backup from this thread...to include recovery....then take your OTA....and flash TWRP afterwards....
Just make sure everything matches your carrier....cid/mid....so the outcome is favorable...g

You'll quickly find, if you haven't already, that the latest Android Revolution HD (v20) requires you to have the latest firmware. Flashing it without it will throw your phone into a boot loop.

If he has removed his carrier's bloatware as well as the custom recovery, would he have to flash the system image also?
Or just flash the recovery?
I am asking as many AT&T users often root to remove AT&T bloatware, like I did. I used HTCDev.com to root, and my bootloader is unlocked.

Flashing a stock RUU will guarantee that the system and recovery are completely stock...
The OTA scans the device prior to update and will detect any software that isn't signed or official...
I'd RUU back to stock...then OTA will prompt....and won't get stuck trying to update the system partition...g
