[Q] Reversing Bootloader to locked

Hi guys,
I just updated my HTC M8(european) to Lollipop and after updating i hardreset the phone, which caused that all my photos and videos are wiped out. As I understood, undeleting files requires access to root and rooting is not possible without unlocking the bootloader. As I found out, it is only possible to unlock the bootloader by the HTC provided token and my question is:
1) is it possible to re-lock the bootloader as the original?
2) if re-locking requires S-OFF, is there any other option then the 25 USD sunshine?
Thanks in advance!

1. No without S-OFF
2. Sunshine doesn't work with Lollipop yet

1. Try "fastboot oem lock" from bootloader
My M8 is also S-ON and I could relock with this method.
You will have "RE-LOCKED" message in bootloader.

I didn't mention that as they said they wanted it locked as it was originally, which can't be done without S-OFF. But yes, you can relock the phone using the above command

HTC ONE m8 4.4.4 unlock bootloader help!

Hello guys, I have had my htc one m8 for a while now and wanted to root the device. After looking through many websites, i realized that you had to unlock the boot-loader. However, when i went to check my fast-boot, i saw that the boot-loader was locked but instead of being S-ON it was S-OFF and i can't unlock the boot loader using htcdev. How do i unlock the boot-loader with s-off?
Kind regards,
Arbaaz

What happens when you try to unlock the bootloader by HTCDev.com? S-off shouldn't prevent you from doing so. If you are having issue with unlocking the bootloader, I have a feeling its due to other factors, not s-off.
Since you are s-off, you can use the following thread to manually change the bootloader flag to UNLOCKED: http://forum.xda-developers.com/showthread.php?t=2708571
Another possibility, is if the phone was s-off by sunshine, the device would still have a valid sunshine license. Just install the sunshine app, and see if you can unlock the bootloader using the app (no HTCDev.com process required to do it this way).

bootloader unlock question

Hello sir. My device. Htc m9. My device already s-off...... on the boot loader screen how to s-on. & how to boot loader unlock plz sir help

You dont ever need to set s-on and you never need to lock or relock the bootloader. If your bootloader says locked or relocked and you want to unlock it then go to htcdev and follow the online instructions for unlocking the bootloader. You MUST use htcdev as that website will email you a key to flash via fastboot. You need htc_fastboot.exe too.

How to Unlock a Relocked bootloader of HTC One E9 S-OFF

Hi
I managed to "Relock" my Unlocked bootloader of HTC One e9 (please don't ask why ) The phone is S-OFF, rooted with fully working TWRP recovery. How can I unlock the phone again.
I've tried the following with no success :
- command "fastboot oem unlock"
-to flash the Unlock.bin again
-the method from this topic https://forum.xda-developers.com/showthread.php?t=2708571
Do you have any other ideas?
Thank you!

hmm... What about trying to unlock it in the RUU?

I just relocked my phone then unlocked it again with the same Unlock_code.bin and the same instructions from htcdev unlock instruction page 4 in download mode. So yeah, it works.
My phone is S-ON though, but I doubt that it matters.
