How To Debrick PW2
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.
