Hey, I've been using Andoird version 2.3.4 for quite a long time now. I've watched and red a lot of tutorials on how to update the firmware of the phone. I did all that root/rom crap and I can't find the proper firmware for the model of my phone. All I found is for the gt-s5830. Every time I use the firmware for s5830 only and not s5830D I get a error status 7. Can anyone give me a link please? I've searched around the internet a lot.
