I tried many roms for my blade but most of them were too heavy and slaggish.
I was searching for a light and fast rom (I don't care much about graphics) so I ended up installing the "swedish snow" rom, and I must say it is by far the best (according to my experience) for this specific phone.
I also set the CPU to "performance" and cancelled all display animations, and the phone runs very very nicely.
Also everything seems to be working as it should so I am quite happy with the result.
Thanks to all who assisted in this rom and guide.
