It was so relaxing and fun because I get the latest Android OS like what is used on the Xperia Arc. Although the upgrade process takes a few failures when using the PC Companion or SEUS. The upgrade process with the PC Companion or SEUS does not run successfully, where Xperia X10 just updated to the latest firmware Android 2.1 Eclair in 2.1.A.0.435. Finally, after going through the process a bit long, successful upgrade process is done through Flashtool using stock ROM firmware 2.3.3 X10 Android Gingerbread.
And just like when using Android 2.1 Eclair, I want to have root access on the X10 with Android 2.3.3 Gingerbread. This I need to install some applications that require root access like droidcap, link2sd, setCPU and many more.
Moreover, with limited internal storage on the Xperia X10, I want to use the application link2sd to move all applications to the microSD although Android 2.3.3 Gingerbread already have this feature. But not all Android applications have features App2SD so should be forced to move to the microSD.
Flashtool itself has a feature to do rooted to the Android devices, but at this time it did not work to gain root access. Flashtool that I use are up to date, but I’m not lucky for now.
So I tried using SuperOneClick v2.1.1 but the results still have not been successful as well. Root process stopped at step# 6, where the application was hang up and not responding so it must exit from the application program.
Actually rooted process was successful for most users Xperia X10, just need a little more ability to perform the process rooted X10. This process is described in the XDA forum to gain access preroot and finally install Android applications that require root privileges.
With conditions like this, I finally decided to wait longer to perform rooted in X10. Hopefully applications such as z4root, gingerbread and or superoneclick immediately updated by the developer so that it can be used by a common user X10 like me . Or will inevitably have to use the preroot method as described in XDA forum.
However you can download SuperOneClick v2.1.1 with gingerbread support for a try. Or you can try the prerooted method from XDA forum to get the preroot access. For now, I just live with unroot Xperia X10 Android phone.
