Can't unlock bootloader for my HTC One S
I'm having issues trying to unlock the bootloader for my One S. I know that you have to go to htcdev to unlock it but even after going through all the steps my bootloader will stay locked.
Just to be clear, I've managed to go through all steps and get my phone to ask whether I want to unlock the bootloader, after clicking yes my phone just turns off. When I go into the bootloader it says locked.
I should also mention that I bought this phone off eBay from a seller who had rooted, s-off and unlocked the bootloader previously. The seller unrooted, s-on and locked the bootloader when they decided to sell the phone. They also mentioned that they installed an official HTC European Rom when rooted.
Any help would be appreciated as I would like to root my phone.
