[Q] Is it possible to go back to "LOCKED" after unlocking bootloader?

I've read that it was only possible with S-off devices, and that you can't do it anymore with stock android 4.2.2. Is there another way to do it?
I haven't unlocked bootloader, rooted and loaded a custom ROM because I'm afraid that in case I need to send it back with warranty(I already had to do it twice), they won't repair/change it for free.
Also, are there any other possible ways of detecting the phone has been unlocked? Perhaps some tips on how to get started? I've never rooted such an expensive phone.

The only way to get a Locked status after unlocking is if you are s-off. The only way (currently) you'd be able to s-off is if you're bootloader is still v1.44. If you've taken any OTAs and your bootloader has been updated, then you won't be able to use the current s-off techniques, so the only way to unlock would be through htcdev.com, and relocking would give you a Relocked status.

Damn I've checked and my bootloader is showing v1.54. A RELOCKED status would void my warranty, am I right?

Not strictly true, you can get s-off with a paid javacard service like fonefunshop. I did this and can now use revone to regain locked status (even on 1.54).
There is also another method detailed here
http://forum.xda-developers.com/showthread.php?t=2475914
but I have not used this personally (yet). All require s-off
This is true.. I was keeping it free and haven't looked at the link you have there

Bootloader says relocked

Okay this is a really stupid question, but I unlocked my bootloader last week and planned on rooting it today. When I enter the bootloader, it says "relocked" instead of "unlocked" the way I remember having it. If I wanted to root, would I have to unlock it again?
Also once I root, do I have to relocked my bootloader? What are the risks if I don't?

yes, u need to unlock to root...no, no need to relock...the only reason to ever relock would be to run a RUU (if you're s-on)
Thank you, I'm now fully rooted

[Q] question about HTCDev .com

hello guys will im currently not rooted for the warranty but there is one thing that bothers me
about the htcdev.com
can my warranty (company, provider, or whatever they called)
check in anyway that i had unlocked the bootloader before
and is the unlcok.bin code linked with my device only (the unlock code when proceeding in unlocking)
dont know why this is coming into my mind
and another question where does the nandroid backup located in twrp and CWM
in future when i reroot the device i want to do a nandroid backup for it

If your bootloader says unlocked or relocked they will know you have unlocked the bootloader. Also "tampered" flag must not shown in the bootloader. Its possible to remove the tampered flag and set the bootloader back to locked (not re-locked) with S-OFF. So if you can achieve s-off there is nothing to worry about.
and is the unlcok.bin code linked with my device only (the unlock code when proceeding in unlocking)

in theory yes, your unlock_code.bin is generated from your phone unlock_token, but never heard of someone who wasn't able to claim warranty because he have unlocked bootloader (with bootloader locked and no tampered flag ---> s-off required)
In some rare cases, HTC doesnt care about unlocked bootloader if its 100% sure the issue wasn't caused by the bootloader being unlocked. It depends which service center. Always better to send the phone Locked + no tampered flag.

TWRP backup are stored at
/sdcard/TWRP/BACKUPS/YOUR_PHONE_SERIAL_NUMBER/DATE_OF_BACKUP/
or if you prefer:
/data/media/0/TWRP/BACKUPS/YOUR_PHONE_SERIAL_NUMBER/DATE_OF_BACKUP/
not sure about cwm, probably something similar.

relock bootloader

anyone know how i can relock the bootloader and re-enable FRP?
is it basically flashing the stock firmware from HuRupdater.zip in twrp
then rebooting into bootloader and issue the relock command
then in boot disable OEM-Unlock?
Hey did you manage to do this?
Anyone manage to do this ? I just unlock my bootlader but havent done anything yet.

Did you ever found this out? I want to unlock the bootloader, but only if I can relock it, because if it's unlocked, the sale value drops. Let me know please =D
Without knowing if it's possible I wouldn't risk it, who knows if Huawei doesn't allow it and you're going to end up with a bricked phone.

Bootloader unlocked not rooted NFC pay not working

I unlocked my bootloader just before the pie update s. I noticed my bank NFC pay stopped working around this time. At this time I don't really need the bootloader unlocked. Is there any harm relocking my bootloader? or possible bricking? If I leave it unlocked how can I hide my unlocked bootloader by rooting ?

This is pretty bad if your bank app thinks that phone is 'rooted' just because BL was unlocked.
If you didn't do anything else (Recovery, eRecovery, Ramdisk, Kernel are still stock), you can relock BL, no harm, it will just Factory reset once again (prepare back-ups)
AFAIK, installing Magisk does not hide from apps that BL was unlocked

Thank you for your response. All are still stock. I just unlocked it a while ago to remove emergency broadcast but did it through ADB instead. No need at this time to be unlocked. Thanks again.
