I came from Froyo DXKB2...
This is what i did :
1. Flash DXKF1 (download & extract files first) using ODIN:
- Open ODIN check Re-Partition, Auto Reboot, F.Reset Time
- Click PIT button chose: latona_20110114.pit
- shutdown phone ...
I can confirm this method is working best when use wifi but no effect when use 2G/3G internet (the battery consumption).
Im on DXKP9 w/ Poseidon's ROM.
I use wifi from 8am to 6pm... and I CAN FEEL THE DIFFERENCE!!!
i cant show u screenshot bt...
