1. I am fed up of my Tipo's lagging touch (responding after half an hour, miscaliberation). I update the firmware using Sony companion and tried to install one of the Jelly Bean roms on the stock ICS using CMW. It some how soft bricked my phone. Can any one tell the reason?
2. With lot of effort I installed the stock ST21a 11.0.A.4.22 Sony Generic kernel (using Flashtool). It is same laggy and miscaliberating. Did I not reformat, similar to PC? shouldn't it be fresh and new ?
3. I am not trying to install JB rom. What is the correct way to install? Should I worry about any seperate parts like Kernel?
4. To install JB rom (Paranoid Android) I tried to root the device, but the flash tool says "no root exploit for this version". If i cant root. I cant install CMW. I cant install frest rom. Is there any other way to install ROM?
I am stuck in the above points after my research, and will appreciate your help.
Thanks in advance
