    This is my first time in this site and I liked it a lot! I have two questions that I’d like to ask you:

    1) I bought a Sony Xperia E1 D2004 and ended up rooting it to get rid of bloatware. But I uninstalled bloatware without making a backup. Did I lose my warranty already?

    2) I still can’t get the official update to Kitkat from Sony. Can something bad happen if I flash the D2005 firmware into the D2004?

    Thanks in advance!

      1. Warranty is definitely lost as you have rooted your device.
      2. We should not flash the firmwares made for other devices, as they won’t suit your device and end up bricking your device.

        Thank you for answering!

        But are you sure that I lost the warranty just by rooting? I used towelroot and some said it could be removed without leaving trace.

        Any idea when I can get the D2004 firmware?
