The 2.3.23 is the worst upload by you yet I feel. I was on 2.2.16 and flashed 2.3.23 on SGS2. Since this was the weekly upgrade, I did it with only cache wipe. Landed up with Kernel Panic upload mode. Had to Odin to stock and then tried to install this after a complete wipe. And landed up with the same. After another Odin to stock I flashed the 2.3.16 which gets installed. You really must check the 2.3.23 file for SGS2. I feel you have some of the highest rate of bugged uploads which you withdraw and re-up compared to other MIUI sites and this really sux.
