Just go to development thread for available custom ROM's. Each ROM's has instructions on how to flash it there too.
1. root ur phone link
2. install clock work recovery via odin link
3. flash custom rom u like link
Just don't forget to back-up your important files like contacts, messages, etc. You can also do a nandroid back-up if you want.

I would've posted links but it's not so simple on app, also if you can't be bothered to search and read on complex topics, which might result in you destroying your expensive phone, maybe you shouldn't be undertaking them.
What's wrong with today's society is people expect everything handed to them on a plate, with little or Jo effort on their part.

+1. I agree. People can't be expected to be spoon fed all the time. Just search it! It's that simple.
What else could we expect from a user (OP) whose nickname seems mispelled?

I don't know what ROM to install or the way to do it. Every help would be great, thanks a lot.

Questions about the GT-S5363

I found a GT-S5363 for cheap at a local market so I picked it up and the seller told me it it a Galaxy S so I bought it because I want this phone so much. But what I found out later it isn't it is a phone on O2. So I searched around this forum and only found ones from 2014 and 2013 but I want those themed Android N on CM 8. They said that ROMs on GT-S5360 works on the GT-S5363 but I don't know newer ROMs will work on that device. So here's my questions:
1. Can I install newer ROMs?
2. How's running?
3. Will it brick your device?
Honestly, I don't have much experience with this era of Samsung devices, I started exploring Samsung stuff starting with the S5 that is toasted by now. I do have a S2 that I still don't have time to fix yet so I don't really have an idea of how old Odin work please help me.
I have the same model. It has absolutely the same hardware as the normal GT-5360. The only difference is the home button and the battery cover, which means all Roms for the normal version should work on this phone as well.
BUT: I tried to install some Custom Roms I found here and it didn´t work. It might be that I´ve done a mistake, but if I was you, I would be careful and ask the developers for their help BEFORE you start.
Good luck!
