Ok. I tried the OTA too, some time ago and after downloading it failed to install. My N3 is rooted and I thought I'd try anyway. But did anyone try to use kies? Some time ago I connected to kies and it told me that my phone wouldn't be supported. I think I installed another region. Yesterday I tried and it told me there was a new firmware although it's not 4.4.2 yet. So it would be interesting to know if it would install after download.
Some other thing: I have something like a mnt folder and one or two other folders like mnt_1. Just like if you update windows and don't do a clean install. How can I do a clean install on my phone once kitkat is released for DBT region?
