Bricked PW1

Hi there,

FOAll I know that I am not on the rigth place but I have a briked kindle PW1.
There are new post so I ask my problem here.

I do not know the past of it.

Only via serial port I could reach it.

I tried to follow this steps from szfisher:

- attach serial cable
- boot
- immediately after restart enter any key to stop autoboot
- enter "bist" and then "fastboot"
- via fastboot tool flash data and diags partitions on PC(windows or linux), img files is here: http://snipurl.com/debrick
- reboot
- immediately after restart enter any key to stop autoboot
- enter "run bootargs_diags ; bootm 0xE41000" to boot to diags
- get login prompy (menu "D) Exit, Reboot or Disable Diags" and then "L) Exit to login prompt")
- login as root (password:fiona2bc)
- enter "echo 0 > /var/local/upstart/lab126_gui.restarts"
- reboot
- after a while, press Enter to enter Recovery Menu
- select "E. Export FAT partition" to export U disk
- copy update_kindle_5.3.1.bin to U disk.
- press 1 to back Recovery Menu
- select "U. Update using update*.bin file on FAT partition" to update root partition.
- select "Q. quit" to boot

I could go until step:
enter "run bootargs_diags ; bootm 0xE41000" to boot to diags

Then I got error message:

uboot > bootm 0xE41000

Straingly:
If I boot then there is no problem to boot but just until like that:

So far I could reach this stage.
Can anybody help me?
Thank you very much in advance.
