1. Download FXP114 ZIP and Gapps (if you cannot download 114, use 113) to SD Card
2. Reboot into recovery
3. Clean cache & dalvik cache
4. Install FXP114 ROM and Gapps114 or Gapps113, whatever you have
(means don't flash FXP114 IMG)
This worked for me, currently I am on ICS 4.0.4.
Changes so far:
EDIT:1. WIFI works better, but some dropdowns still experienced.
2. Panorama does not work (I do not matter.)
3. Videoplayback (Youtube) does not work (?)
Conditions Change. Results Should Not.
