Im using Samsung Galaxy Young, rooted already .
Android version : 2.3.6
Baseband version : S5360DXLL1
Kernel version : 188.8.131.52 dpi@DELL158 #1
Build number : GINGERBREAD.DXLL1
Can upgrade my android ? How ?
These are nightly builds so they are barely tested and buggy so use at your own risk. Directions inside the link on how to install. This guy is working hard to port this to your device so show him some love by thanking his post.
By the way it looks like the samsung galaxy y is not very popular in the custom rom community so finding mods may be difficult.
