[Q] About official updates and relocked bootloader

Hello, I have a One X that I relocked the bootloader for send it to HTC. Actually my One X is running a official 4.0.3 version and always says that I have new updates availables.
I want to know if I need to do something special to update it without bricking the phone or I can do it normally.
Also I have doubts about if now with my relocked bootloader I can unlock it with the same process that I use the first time that I did it.
Thanks in advance.

If you are fully stock....
Stock Rom (not rooted)
Stock kernel (boot.img)
Stock recovery
You can leave your Bootloader locked, should not be a problem !

Thanks for your answer, I have stock rom, kernel and recovery. What about the process to unlock again the bootloader for install custom roms? Can I do it like the last time? Thanks in advance.

The process is exactly the same. You can even use the same unlock code .bin file to unlock

How to lock bootloader and sim for warranty?

I need to simlock adn bootloader lock my phone for warranty,is there a tutorial how to do this?

I don't think SIM lock is required for warranty.
Give us a little bit more info, do you have a custom recovery installed? Custom Rom? If not and the only thing you have to do is lock the bootloader then the command is
Fastboot oem lock
Note: don't do this with a custom Rom or custom recovery it will result in a bootloop. For completely stock you need
Stock rom
Stock boot.img
Stock recovery.img
Locked or relocked (warranty)

I have custom recovery ClockworkMod Recovery v5.8.4.0
custom rom android revolution hd 18.2
cid htc__032
hboot 1.39.0000

Only thing you can do is install the stock rom and the stock recovery, RELOCK the bootloader. Lock is NOT possible

Off:can't login to that account.
I did restore stock room with ruu.

Are you take the code from them or you take the code from some website? You can't lock the sim but you can try to send the phone with sim unloked and hope they will not see this. And something else Vodafone not repear OneX they send the phone to some other service I think!

Three UK Model - Flash to stock?

My Three model comes unlocked but is already behind when it comes to firmware. It also only has the APNs for Three (so I have to manually input for any other SIM I insert) and there's an annoying splash screen.
I'm not very well-read when it comes to flashing HTC devices but am I right in thinking that there is no way to flash stock firmware without S-off and bootloader unlock? One good thing about even the Sony handsets is that you can flash stock firmware without going through hell.
If I'm wrong could someone point me in the right direction. Not the end of the world if I can't 'stockify' but it would be nice

Just flash the stock Rom from Mike in the dev thread.
No need to change firmware. That would take s-off anyway.

Does this require boot loader unlocking or a simple flash?

Unlock bootloader.
Flash a recovery through Fastboot -
Fastboot flash recovery recovery.img
Put rom on sd
In recovery backup current rom, then flash custom rom

Hmmm I'd have to have the 'tampered' warning and lose my warranty that way wouldn't I?
Might just live with it for now. Thanks though.

You won't lose warranty no.

I thought if you unlocked the bootloader it invalidated the warranty? Or have things changed?

That's a common misconception.
Unless you broke the actual hardware, they are still liable for it

As long as the issue isn't blatantly caused by unlocking it, there won't be a problem.
Mine have been s-off and unlocked. They just send them back locked and s-on

If I flash this stock ROM will it receive OTA updates just like a normal stock phone?

No, though you wouldn't need to the updated custom Rom will be out before the ota is.
Of course you can always go back to stock if you keep your backup.

I don't want to mess with flashing ROMs other than for this so I'll probably just leave it as it is. Thanks for your help anyway.

questions about returnig to stock - warrenty

I have to get 100% stock for warrenty.. my devices is s-off, custom recovery, bootloader unlocked and custom rom. Will i get to stock with these steps: ?
- flash the stock rom (from my nadroid backup)
- flash the stock recovery
- set the bootloader to "locked"
- go back s-on
do i need an unlocked bootloader to get s-on ("writesecureflag 3) ?
Thanks!

If you used htcdev to unlock the boot loader, this can be a problem since HTC can see it!

If you're already on stock Sense 6 before doing these steps, I would think flashing stock recovery is enough. Then you can manually boot into the OS and do a factory reset from within the settings, before sending it off for warranty repairs.

You can try spoofing S-ON status through hboot. I have not tried this before, so proceed with caution. You can read about it here: http://forum.xda-developers.com/showthread.php?t=2708721.

Does it work to flash files (.zip & recovery) with a locked bootloader but s-off? And is it possible to get s-on with a locked bootloader?
Okay, thanks guys! I just "stocked" my phone The only thing that´s left is s-off. Do you recommend to go back s-on?

I successfully returned my M8 back to full stock (no root, locked bootloader and S-On). I wrote about my experiences here: http://forum.xda-developers.com/showpost.php?p=55374704&postcount=7

I'm not totally sure but you may have to downgrade in order to unlock your bootloader. And I don't think there's an official way to relock it, but why would you want to?

Flashing raw firmware can re-lock your bootloader.
OR
Flashing any MM Build with Stock Recovery can also re-lock your bootloader.
