How To Debrick PW2

[quanom]

Hi everyone,

I've searched the forum for hours and the only one who came up with a solution is san3 but I have couple of questions about it because I haven't used Linux before. I couldn't understand the steps he mentioned.

Assume that I am the ultimate noobie; here it goes:

• Serial connection to the paperwhite using rs232to usb converter (type PL2303)
  Baud Rate 115000
  
  How do you do it? Can you tell me step by step? Is there a guide somewhere?
  
  You mean this converter:

  Or should I use serial port at the back of PC chassis:

• Interrupt startup and enter uboot
  
  How do you do that in Linux?
  
• uboot > "printenv"
  [...]
  bootcmd=bootm 0x41000
  bootcmd_diags=run bootargs_diags ; bootm 0xE41000
  
  I suppose, when in uboot, I should write to command line "printenv" without quotes. Then I should note result values for the next step.
  
• Boot into diags partition with:
  "bist"
  "run bootargs_diags ; bootm 0xE41000"
  
  Then I should execute these commands based on values I got before.
  
• Select USB mode, copy mmcblk0p1 bin image to kindle
  Quit menu Exit to login prompt, login as root
  
  "dd if=/mnt/us/mmcblk0p1.bin of=/dev/mmcblk0p1 bs=4K"
  
  Can you explain step by step? For instance, how do you login as root?
  
• reboot
  remove all the logs:
  "rm -f /var/local/upstart/lab126_gui.restarts
  rm -f /var/run/upstart/lab126_gui.restarts
  rm -f /var/local/upstart/x.restarts
  rm -f /var/run/upstart/x.restarts
  rm -f /var/local/upstart/mesquite.restarts
  rm -f /var/run/upstart/mesquite.restarts"
  
  Should I reboot with a specific command? Do you mean reboot the computer? If you did mean the computer, should I run these log remove commands in uboot mode?
  

Well, I warned you about my ultimateness of my noobie skillz. Will you help me fellas?

Thanks.
