Certain Android mobiles are locked with their bootloader. Once bootloader is locked, you can not root or flash new ROM.
You need to know that bootloader is different from root. If you have unlocked bootloader, then you can flash recovery through bootloader or root with Unlock Root. After root or flash new ROM, you are free to optimize your phone.
You also need to know that not all claims resulting or caused by or from the unlocking of the bootloader may be covered under warranty. Unlocking your bootloader does not mean that you will be able to unlock the SIM lock. Unlocking your SIM lock is at the discretion of your operator/carrier and is not part of the bootloader unlocking scope. |
