I have a new Xperia Compact from O2. O2 branded (splash screen & a few apps), unlocked (via eBay code) and unrooted. I'm not worried about backing up because the handset is still fresh with not much on it. I do not wish to root because certain apps I require will no longer work. This is my first Sony handset in years so I'm hoping one of you more experienced folk can help me.
1. Can I download any generic ROM from here and install it using Flashtool?
2. Will it remove the O2 branding permanently?
3. Will I be able to receive OTA updates in the future or will I have consigned myself to using flashtool for every update?
Thank you in advance.
Yes, you can flash JB or the new KitKat but I recommend keeping the phone on JB because the update for KK has bugs, like battery loss, sound stuttering and many more
Download the latest flashtool, it's very easy to use even as a "new player", check wipe for all and it should do the trick.
As far as the O2 apps, I believe they will be removed with a fresh flash of a new firmware if you do a complete wipe and OTA will work as long as you don't unlock bootloader, at least for sony firmware.
