Please i need help in unlocking htc one s bootloader and rooting it, if you stay in kaduna and can do it please drop your contact so i can get in touch with you. I don't have a pc so can't do it myself since the procedures require using a pc. Thanks in advance

There can be many ways to get your unlock code. If your contract period is complete you can ask your cellular operator for the unlock code. But, they do make it very difficult for you to get the code.
You can also visit http://www.theunlockarena.com/htc-one/rs13wp9/ and can see different options there to get unlock code for a price. Make use of this site and unlock your mobile without vain..
