Root (su) by it's self does not stop you from getting OTA updates
changed system files / missing (data/preload) files and custom recovery are what stop you from getting OTA updates
a rooted phone will update fine / you just loose root

when you unlocked the bootloader you already lost some system files (data/preload)
depending on your phone model, their are already stock rom backups you can install along with stock recovery to take OTA updates
you get these stock backups by flashing a RUU, with s-off you don't need to lock / unlock the bootloader so all the system files are intact

but as i know unlcoking bootloader, do not stop OTAs, Its a bit diffiult to find RU, for my phone model, but however ,i just wanted to know, if i install TWRP, then root, then flash again stock recovery, will i be able to get OTA again ?
or instaling TWRP, i just break OTA Updates ?

The second problem of unlocked bootlader is even more serious, but so far it affects only 2 devices: HTC One X+ and HTC One. Those who used htcdev.com before probably noticed, that unlocking bootloader wipes user data, including content of virtual SD card (because virtual SD card = /data/media).
This is no surprise, because every user is warned about it and have a chance to step back. As long as all applications coming with stock ROM are stored on /system partition, there are no side effects. But for some very strange reason in HTC One X+ and HTC One, some of the stock applications like Flashlight, Calculator, Ringtone-trimmer, PDF Viewer, Teeter, Sound Recorder and more, are stored on /data partition instead. Result? After unlocking bootloader with official HTC tool you end up without having some of the basic HTC applications like Calculator or Flashlight, because /data partition (as mentioned above) has been wiped. System partition on HTC One is almost 2 GB big. Not enough to include few more .apk files?
What is more, missing stock applications on /data partition makes your device not capable to receive any OTA updates from HTC. Why? Because every OTA update checks MD5 checksum of every file that originally came with your device. So even if you didn't flash any custom ROM and your /system partition is unmodified, you won't be able to install OTA update.
This is an example of updater-script part from OTA:
assert(apply_patch_check("/data/preload/Calculator.apk","85aa7b00ec97ffe7179739c8815bf102c4f8666e","7055f0376e6b56be6414fdf8495b82db7fd38564")||apply_patch_check("/data/preload/Calculator.apk.uninstall","85aa7b00ec97ffe7179739c8815bf102c4f8666e","7055f0376e6b56be6414fdf8495b82db7fd38564"));
Once assert will fail, OTA update will cancel the installation process. I think every user should be warned, that unlocking bootloader results in no longer OTA updates support.

The bootloader status doesn't matter, you can be locked/unlocked/relocked and the ota will work fine but you must restore all the content of /data/preload for ota update to install
B) the OTA updater-script
you need to be on stock recovery, custom recoveries will not work!
what will it check:
1- the ROM fingerprint, CID, and MID
2- if you pass those, the OTA will check the actual system files (thousands of them) using SHA-1 hash to confirm they are as expected. Why? because OTA is just a patch (diff) between two versions, so in order to patch a file (as opposed to replacing it), it has to be an exact match.... if even 1 out of those thousands of files is not as expected, the OTA will not work. ---> stock recovery will change to red triangle.
Note: this also usually includes the /data/preload folder which gets deleted when using HTCdev unlock.

If you have 100% stock /system, /data/preload and stock recovery you will able to install ota update, Bootloader status doesn't matters, only the files that are deleted when unlocking it the first using htcdev.com:
I'm being lazy here, sorry ,but I did promise to post something
A) when do you receive and OTA notification:
1- the ROM fingerprint, CID, and MID must match (if) available OTA
2- does anything else matter (root, kernel, modifications, S-On/S-Off, etc., even recovery) -> NO, but they may below
B) the OTA updater-script
you need to be on stock recovery, custom recoveries will not work!
what will it check:
1- the ROM fingerprint, CID, and MID
2- if you pass those, the OTA will check the actual system files (thousands of them) using SHA-1 hash to confirm they are as expected. Why? because OTA is just a patch (diff) between two versions, so in order to patch a file (as opposed to replacing it), it has to be an exact match.... if even 1 out of those thousands of files is not as expected, the OTA will not work. ---> stock recovery will change to red triangle.
Note: this also usually includes the /data/preload folder which gets deleted when using HTCdev unlock.
what will it do if the above are OK:
* the OTA will patch the existing files
* delete any files no longer part of the update
* install any new files that come with the update
* and finally update the firmware (hboot, recovery, kernel, thouchscreen drivers, bootsplash, etc.) <- note, since the OTA is an update the firmware.zip will only contain the files that need to be updated, so for example, touchscreen drivers are not included in every OTA, only when necessary.
and to the big question, what will interfere with successful OTA:
any modification to the files the OTA checks (in step 2 above), so:
- does a custom kernel matter (boot.img) -> technically no, but custom kernels may also overwrite certain system files, so in practice yes they may interfere if some stock system file was changed.... not because boot.img is custom, but because the files in /system which got replaced. (so flashing back a stock boot.img will not solve this!!)
- does root matter -> same as above, if the root package modifies any original files then yes, otherwise no
- unlocked bootloader -> No, doesn't matter
- S-On/S-Off -> No, doesn't matter

So if you still have all files in /data/preload its okay even if your bootloader is unlocked.

Hi today i got the 4.4.2 update and i tried to install it and it failed
My current situation is:
Tempered
Relocked
S-ON
Completely stock (I was rooted, xposed, sense 5 toolkit, htc hand font) by flashing firmware.zip and relocking the bootloader and i created (data/preload/apps) and put every app that comes with the same directory in the OTA and flashing htc stock font back and i've done a factory rest to make sure everything is stock :good:
every time i try to install the update i got ("/system/bin/app_process' has unexpected contents Installation aborted)
by the way my CID is HTC_044 and i'm on 707 region
Anybody have any idea to help please don't hesitate to share it

Looks like you're not stock after all.
You say you were using Xposed. Xposed replaces /system/bin/app_process with a patched version. By flashing firmware.zip you did not revert your system to stock, only your firmware, that is recovery, kernel, radio, hboot and other firmware partitions, but *not* /system. Which means you still have the Xposed version of app_process on your phone, as well as any other additional mods you installed.
To get to stock, you'll need to restore a backup of the stock system without any mods installed. Neither relocking the bootloader nor S-ON/S-OFF have any effect, you can apply official OTAs with both S-OFF and unlocked bootloader just fine. You don't need factory reset either, the contents of /data don't matter to the OTA at all. What you do need is a stock /system and stock recovery. Of those two requirements, you only fulfilled the second.
If you do not have a clean backup of the stock system, you can either hope that someone else has one and is willing to share it, or you can change your CID to either HTC_622 or a super CID and use the stock ROM I posted over here
All done

Thank you it went well :victory::victory::victory::victory:
I replaced the app_process with the one from your nandroid backup and the update process was successful :laugh::laugh:
I rooted my HTC One a while ago.
Recently, I got the request from my phone to preform a system update. I wasn't used to my phone being rooted and forgot it was rooted and preformed the update. When the update tried to install, it opened up my recovery (ClockworkMod Recovery) and rebooted my phone (I guess this is the normal reaction).
I really like my phone to be up-to-date. How can I get the official 4.4.2. update on my phone?
(If necessary, I wouldn't mind losing my root access in the process as long as I can root back after the update. However, I would prefer my Bootloader to remain unlocked so I won't have to format again.)
I am very interested in Android, but i know very little about things like this so please, if you know how, explain it to me step by step without leaving out little details.
Thanks in advance.

Many things are required to flash ota updates. First one is the stock recovery, you can't install an ota update with a custom recovery like cwm or twrp. So flash back the stock recovery that match the version you have on your phone. If you have modified or deleted files in /system, you'll have to revert those changes. The updater script of the ota update MD5 cheksum these files. If only 1 file doesn't match the expected value, the installation will fail. Same thing apply to preloaded app that get wiped when you unlock bootloader (calculator, flashlight etc...)
So first, flash your stock recovery and try to install the ota. If it doesn't work, post the output of ''fastboot getvar all'' (except imei/sn) and we will check what you can do to updates your phone

HI there,
I have a rooted HTC One M7 Stock ROM hboot 1.57 S-ON and now I got the following update:
Software update: 6.14.111.2 (659.71 MB)
System improvements
-Android 4.4.3
-OpenSSL security improvement
Application updates
-Camera
-Gallery
-HTC Sync Manager
My question is, how can I apply the update? I already tried but since I have twrp as recovery it didn't go through. Is there a way of applying the update without losing root and my current configuration (contacts, apps, SMSs, etc)? Should I try to get S-OFF first? (I already tried to no avail like two months ago)
What is the best option to get it working with the latest software version? Sorry if my questions seem a bit too noob. I already tried looking for a similar thread.

You must be 100% stock for ota updates, stock recovery and stock rom (untouched /system and /data/preload files). /data/preload is wiped when unlocking bootloader.

you first need to flash your stock recovery back and then the content of /data/preload if you can find it for your version. Otherwise you will need to restore your phone back to stock or to use custom roms.

Yes you should be able to run the OTA updates if you have stock recovery for your version and the content of /data/preload for your version. Best way to know is to flash you stock recovery back and try the ota. If the ota fails, enter the stock recovery menu and you'll see why the ota installation aborted (which file is missing)
Will I lose root access?

It depends.
rooting itself doesn't prevent ota updates to install. As long as all your /system files and /data/preload files are 100% stock, ota updates will install fine.
But unlocking the bootloader will wipe everything in /data/preload so you won't be able to install ota updates (even if your phone will notify you and download the update) unless you have restored this folder and its files after having unlocked the bootloader (either by using a ruu, restoring a nandroid backup, using a reset rom). You can also manually restore that folder if you can find the files you need but they most be from the same exact software version (e.g: you can't use /data/preload files of 5.09.401.10 on 5.09.401.11 in order to update to 5.09.401.12).
http://android-revolution-hd.blogspot.ca/2013/03/negative-effects-of-unlocked-bootloader.html
Just check if you still have HTC calculator and flashlight app installed on your phone. If not, then its because you don't have /data/preload on your phone and ota update can't be installed.

ok thanks sir, ill keep for sometime unrooted, , its working great
Hey , im new to rooting and the forums so sorry if somethings are not properly explained.
I recently managed to root my uk variant m7 unlocked to any service with the latest twrp recovery.
I have recently found the venom rom which i would like to install to futher customize my rooted device, but i need to upgrade my android to 5.0.2 and i am currently on 4.2.2.
in the toolbar it says 'system update avaliable' and after installing it says 'system update ready' and im guessing this will bring me to 5.0.2 firmware. after clicking on it it reboots my phone and for some reason enters the recovery. from this point i do not know what to do.
so to summarise, i need to upgrade my m7 from 4.2.2 to 5.0.2 nut when i do it enters my twrp recovery and i do not know what to do
system details:
HTC One M7 UK variant unlocked to any service
rooted with SuperSU
Stock rom (4.2.2)
Stock kernel

You can't update your phone in its current status. You need stock recovery installed, unmodified /system files and /data/preload which is deleted during the htcdev bootloader unlock process. You'll probably need to use a RUU or something else.

A factory reset only wipes user data. Root files are stored in /system partition which is not affected by a factory reset so short answer no, like I said you'll probably need a RUU or something else (stock odex rom/nandroid backup/guru reset rom) to reset your phone back to stock. Post the output of "fastboot getvar all"

If your phone is S-off, you can download the Ota zip files and install them incrementally (can't skip a version) using stock recovery. That doesn't change the fact that all files in /system and /data/preload must be unmodified.
Imo, the simplest way to update if your phone isn't stock is with a RUU. If your phone is stock, reflash stock recovery and update with Ota, if it's stock and soff you can update with Ota zip files if you can find all the ones you need.
