I've never heard of this. Are you using flashtool?

No, I used fastboot. I used the same for unlocking the bootloader..

BTW should I try flashing the kernel using flashtool' fastboot?

Are you comming from a stock rom? An older version of this rom or a totally different rom?

are you sure you are using
fastboot flash boot boot.img?
cause you might be just hotbooting it instead of flashing

New kernel for CM9/AOKP.

Based on new Sony sources.

Deep sleep is fixed, and so is video decoding

Enjoy, watch videos and have deep sleep

I was on stock ROM firmware 42 AFAIR , bootloader unlocked and was using DoomKernel 2.0Ghz kernel.

I think I did flash the kernel because if I didnt, how would I had seen the FXP bootscreen?


All right, I used flashtool to flash kernel and now it booted..

I have had that happen before as well. Try doing fastboot -i 0x0fce erase boot first.

What's the battery life on this? If it's more than 15 hours I'm flashing this.

Yes, with Deep Sleep working it's more than 15 hours.
