Custom Rom install help..

What Custom Rom's are compatible with Sam Sung Galaxy Core Prime SM-S820L.

I've rooted this Android cell phone and tried to remove all the bloatware the phone had that I didn't want. Mainly haven't used this phone as anything but a facebook phone when connecting to WiFi.

But it seems I may have removed the "wrong" thing in turn the WiFi no longer connects. Probably broke the core of the OS..

I can still factory restore, if I hold volume up, home and power; then release home and power. I've deleted the cache and done factory restores that way.

I tried to unlock the boot loader with my computer but..

I can't seem to find the correct driver for the: Sam Sung Galaxy Core Prime SM-S820L.

To reinstall another rom OS, I think I have to unlock that boot loader first right? Then it connect the phone with usb debugging and download the rom from pc to phone while in: Downloading Custom Rom mode?

Anybody with any information about Sam Sung Galaxy Core Prime SM-S820L, would be very helpful - I just mainly use it for fun. But now I can't connect the device to my router its a real shame.

Thanks in advance!
