Question HELP! My KPW1 need help!

Hi,guys. I have made some mistakes when I fix brick(kindlepaperwhite one).
I had done the "Erase MMC0", and then "Export FAT partition". After that, I tried to open it, but the computer could't read the disk, so I choosed the optin to format it, then I copied the upgrade package inside, after "Update using update*.bin file on FAT partition", It showed me something, but I had no idea what to do, so I ended the connection. Then I tried to set up the connection again. It showed me this as follows:

? - alias for 'help'
bist - start Built In Self Test
boot - boot default, i.e., run 'bootcmd'
bootd - boot default, i.e., run 'bootcmd'
bootm - boot application image from memory
go - start application at address 'addr'
help - print online help
idme - idme - Set nv ram variables
log - manipulate logbuffer
printenv- print environment variables
reset - Perform RESET of the CPU
run - run commands in an environment variable
setenv - set environment variables
version - print monitor version
uboot > bootm
Wrong Image Format for bootm command
ERROR: can't get kernel image!
uboot > ?
? - alias for 'help'
bist - start Built In Self Test

help - print online help
idme - idme - Set nv ram variables
log - manipulate logbuffer
printenv- print environment variables
reset - Perform RESET of the CPU
run - run commands in an environment variable
setenv - set environment variables

You are now toast.
or at least your PW1 is.

"Erase MMC0" does just what the label describes - -
Including the user and device specific information **outside** of the partitioned portions of the flash chip.

So unless you made a copy of that section of the flash storage yourself . . . . .

- - - -

What you see is the u-boot (bootloader) prompt -
but only a reduced command set version.

Run the "bist" entry to reach the full command set version of u-boot (if it is still there, it probably is).

google: u-boot or uboot
