    Default I think I bricked my HTC One M8 ....

    Hay everyone, was wondering if anyone can help me out?

    I had cyanogenmod installed, wasn't a fan so wanted to go back to sense, after many failed attempts I know have a phone that is stuck in the bootloader I think (has pink text up top saying relocked)

    I am clueless as to what to do to get it back working. One tutorial I was following had me relock the bootloader. The phone is now s-on also.

    Its a UK 02 model. CID O2_001 if that helps.

    Even if someone can point me in the direction of a fix it would be greatly appreciated.

    Do you still have the unlock_code.bin on your computer? You can re-unlock the phone that way. Just make sure to be in fastboot.

    the unlock was done in a command window. The command was 'fastbook oem lock' or something along those lines

    That's after you unlocked the bootloader. To unlock the bootloader, you have to go to HTCDev and get it unlocked. They send you a file callec "Unlock_code.bin". Do you still have it? If not you can try this:

    1. Try the "fastboot oem unlock" command
    2. Go through the HTCDev unlock process again.

    Do you still have access to fastboot?

    Can you access recovery? What do you have? TWRP?

    If you have S-ON, you need to flash the boot.img after you flash the ROM or else it will be in a bootloop.

    Do you know how to do that or would you like me to assist you in that as well?

    Flash the ROM in recovery first, then boot into fastboot.

    Okay, inside the ROM you are flashing (ROM.zip), you'll find a file called boot.img. On your PC, copy the boot.img file and paste it inside the folder that has your adb and fastboot files.

    Open up CMD, and change the directory to that folder.

    Type "fastboot flash boot boot.img"

    Once it flashes, reboot the phone.

    Let me know if it boots up then or if you encounter any trouble.

    Don't be afraid to ask questions if you are unsure!

    Hmmm...

    You're going to have a tough time returning to stock I'm afraid. Once you have unlocked the bootloader, rooted, etc., the phone will display a "tampered" and "unlocked" text in the bootloader screen. It's really hard to go completely back to normal!

    If you want a Sense ROM, it's easy to flash that. There's tons of Sense ROMs on XDA.

    The only way I can think of returning to stock would be to flash an RUU. I think you would need S-OFF for that.

    I highly suggest you just stick with the custom ROMs and not go back to stock. The perks are well worth it.

    Yeah, definitely check out the Sense ROMs. If you have any other questions, I'll help you out.
