You didn't erased U-Boot (because it's located in special "hidden" partition).

I need to know how can i flash the partitions using the serial port when everything was wiped out from the kindle?

Well, but you definitely did erased your Board Id. And U-Boot now doesn't know how to initialize RAM (as shown by log in your next post), so it couldn't proceed further.
I guess, one of the ways to recover system would be building of custom U-Boot (from Amazon sources) where selection of RAM initializing code will not depend on Board Id, but rather will be "hardwired".
Oh, but there is an easier way
U-Boot also provides command idme
idme - Set nv ram variables
idme <var> <value>
- set a variable value
- print out known values
Available variables for setting values: serial, accel, mac, sec, pcbsn, bootmode, postmode. I guess, you should set serial
