Yesterday, I tried to update firmware to 4.0.1, but unsuccessful (an error occured and then can not boot into the main mode).The mmcblk0p1 I used was downloaded from internet:"http://pastebin.com/tx8q9a8N"

Just now I did the following:
1 fastboot.exe flash kernel kernel-4.0.1.img
2 dd if=/mnt/us/mmcblk0p1.img of=/dev/mmcblk0p1 bs=4K
3 dd if=/dev/zero of=/dev/mmcblk0p3 bs=4K count=1K

After that, the diags still has no response when I try to boot into the main mode.Is there anything I missed in the unbrick precedure above?

Thank you all the same.

Some your backup or downloaded one from the internet?
If you used from internet (here), have you had update your firmware to 4.0.1 before?
If no, there is probably conflict.

So if you haven't before updated firmware to 4.0.1, download K4 4.0.1 kernel from links above and flash it with fastboot or dd.
(fastboot.exe flash kernel filename.img)
