HTC Desire 310 Problems

Hi Guys,

I am new to the world of android modifications and have been trying to upgrade my HTC desire 310 OS to 4.4.2 or higher. The reason for this is that PokemonGo is not supported on anything lower than 4.4.2.

After much research I have managed to install the firmware for the 320 onto my device (Comes with 4.4.2) which seems to be working fine, except that the WiFi does not work or the GPS (Strange though that after the factory reset, the WiFi worked for a couple of seconds and then disappeared).

I have seen that some people are running CM 12.1 or even 13, and have advised that this sorts out the wifi and gps issue, therefore I have been trying to flash this.

It is my understanding that I will need to follow the below steps:
1. Flash CWM
2. Unlock bootloader
3. Flash CM 12
4 Flash Gaaps

Now the problem that I am having is that when I try to sideload CMW I get the error "installation aborted apply adb sideload"
How can I get this to work?

I have also not been able to find a guide that I trust for unlocking the bootloader ( I believe this is reqiured)

Please can someone help me with this as I fear I will not be able to understand this process without some assistance.

Thank you all :)
