I'm having a problem with rooting Prestigio PAP5400 DUO smartphone. I had recently updated it to the newest firmware and later tried to root it with various software. SRSRoot couldn't do that, tough it showed, that previous firmware was rootable, so I am asking if whether it is still possible to somehow root it or can anyone help me with downgrading, there are firmware versions to download from official support page, but no idea how to downgrade and if it's even possible. The main reason why actually need rooting is to increase RAM thrue Ultra speed SD card, since quad core and 512 Mb RAM ain't exactly the best couple... Perhaps there is somethig else do that without the RAM managment software and root acess. I don't know if 125-50 or less free RAM is normal, since the aren't a lot of apps in it, and even if i clean them, they tend to restart sometime after, I don't want to uninstall them tough, just more RAM and for that I need solutions for the previous requests. Would be good enough to know if there is an expert that can solve these problems.
