I was trying to uninstall U-boot by flashing a new kernel from inside the shell. It didn't boot after all, so I decided to use flasher to boot some kernel from RAM.

I extracted zImage-2.6.28-maemo19.fiasco from some kernel deb file (maybe it was a mistake?)
And then I loaded it by doing:
flasher-3.5.exe -l -k zImage-2.6.28-maemo19.fiasco -b

It got loaded once, though the phone did not boot. So I switched it off.

But now, when I plug in the USB cable and it starts showing the NOKIA logo there is no more USB icon in the corner.
It doesn't load any more imeges from my flasher

Please advise me what to do.
