I purchased an imported xperia z1 a few months ago. It was sold to me rooted and installed with custom rom android 4.4.4. Now i want to just want to clean install with the same thing. I fear that it will get locked or my phone will stop reading my sim if i do reset from settings. My phone came with an app NDR utils. I guess i have to do it from there. Any idea which option to select??
