I have recently decided to change the OS on my Sony Ericsson Xperia Mini st15i android phone. I want to install the cyanogen mod 10 OS on this device. I have done some research on this topic, but still have a few questions. Just wondering if you can help me out in this regard. I know that rooting my phone will void my warranty and I am ready to accept this and any other circumstances that come with this procedure. With that said, here are my questions about installing a custom ROM on the phone. Also my phone is factory unlocked.
1- Do I have to root my phone?
2- What version of Android should I have running or should I downgrade to in order to install this Rom?
3- Can I get a list of software, preferably with download links for this procedure?
4- Is it possible I can get a step by step guideline from rooting to installing the custom.? ( most of the online help sites tend to leave out one or more parts.e.g. rooting, what version of android OS I should root to)
Thank you very much for your kind assistance.
