Hey guys, if you've been following the Sideloading and Whispersync thread, you've seen that there have been some cool new developments about getting your books (not purchased from Amazon) to sync across different devices.

It turns out that Amazon will sync your books across multiple devices if they appear to have a legit ASIN number. But if you have an Android or iOS device, it would sometimes not download the correct book cover because it couldn't associate that ASIN number with a Kindle book. So to solve that problem, I wrote a couple of scripts (one for Windows and one for *nix). They will automatically download the correct ASIN number from Amazon. If it cannot find a match, the script will just give you a random ASIN number so it will still sync between your devices.

Let me walk you through doing this:

-Backup all your .mobi files before trying this!
-Get an Amazon Web Services account. It takes about all of 2 seconds. You'll need the API and Secret keys

Windows:
-Download and install Python
-Download and install SetupTools
-Install python-amazon-product-api
-Make sure C:\python27 and c:\python27\scripts are in your PATH Environment
-If you can't do the "easy_install" download and install this
-Put all your .mobi files in a single folder
-Download MobiPerl and extract it to the same folder your .mobi files are in
-Save this file as a .bat file in that same folder:

@echo off & setLocal EnableDELAYedExpansion

del temp*.txt>null 2>&1
set "asin1=B00"
set /a count=0

for /f %%a IN ('dir /b *.mobi') do (set /a count=count+1)
echo Number of files: %count%

set /a diff=((9999-%count%) - 1000) + 1
set /a divisor = 32767 / %diff%
set /a diff2=(999 - 100) + 1
set /a divisor2 = 32767 / %diff2%

:Random1
set /a asin2=%random% / %divisor%
if /i %asin2% GTR 9999 goto Random1
if /i %asin2% LSS 1000 goto Random1

:Random2
set /a asin3=%random% / %divisor2%
if /i %asin3% GTR 999 goto Random2
if /i %asin3% LSS 100 goto Random2
set /a temp1=!asin2!

for /f "delims=  " %%b IN ('dir /b *.mobi') do (

C:\Users\m0ngr31\desktop\kindle\mobi2mobi.exe --outfile "%%b" --delexthtype 113 "%%b">null 2>&1

C:\Users\m0ngr31\desktop\kindle\mobi2mobi.exe "%%b" > temp1.txt
findstr /i "longtitle" temp1.txt > temp2.txt
set /p title1=<temp2.txt
set title1=!title1:~11!

find /i "item: 100" temp1.txt > temp3.txt

for /f "tokens=* delims= " %%a in (temp3.txt) do (
set var=%%a
)

set author1=!var!
set author1=!author1:~33!

python asin_search.py "!title1!" "!author1!" >temp4.txt

set /p temp2=<temp4.txt
set temp2=!temp2:~0!

set filename=%%b
call :movement %%b
)

:movement

if "!tempfile!"=="!filename!" goto :end

find /c /i "b0" "temp4.txt">null 2>&1
if !ERRORLEVEL! EQU 0 goto :real

:fake
C:\Users\m0ngr31\desktop\kindle\mobi2mobi.exe --outfile "!filename!" --exthtype 113 --exthdata "!asin1!!asin3!!temp1!" "!filename!">null 2>&1
echo Gave a fake ASIN number to: !title1!. It's new number is !asin1!!asin3!!temp1!
set /a temp1=!temp1!+1
goto final

:real
C:\Users\m0ngr31\desktop\kindle\mobi2mobi.exe --outfile "!filename!" --exthtype 113 --exthdata "!temp2!" "!filename!">null 2>&1
echo Gave a real ASIN number to: !title1!. It's new number is !temp2!

:final
C:\Users\m0ngr31\desktop\kindle\mobi2mobi.exe --outfile "!filename!" --addexthtype 501 --exthdata "EBOK" "!filename!">null 2>&1
set tempfile=!filename!

:end
del temp*.txt>null 2>&1
del null*

-Replace "C:\Users\m0ngr31\desktop\kindle\" with your working directory
-Download this python script and save it as asin_search.py in your working directory

import sys
from amazonproduct import API

AWS_KEY = 'A******************A'
SECRET_KEY = 'h*************************************7'
api = API(AWS_KEY, SECRET_KEY, "us")
node = api.item_search('KindleStore', Title=sys.argv[1], Author=sys.argv[2])

for book in node.Items.Item:
	print '%s' % (book.ASIN)

-Replace with your own API and Secret keys
-Run the .bat file and wait for it to finish.
-Copy the updated files to your kindle, android, iOS, etc.
-See if it worked!

*nix:
-Make sure mobiperl is installed correctly (MAC) (Linux)
-Install python-amazon-product-api
-Put all your .mobi files in a single folder
-Save the above python script as asin_search.py in your working directory
-Replace with your own API and Secret keys
-Save this bash script as a .sh file in your working directory

#!/bin/bash

count1=0
asin1="B00"

FILES="*.mobi"

for g in $FILES
do
	if [ "$g" ]
	then
		count1=$[$count1+1]
		continue
	fi
done
echo "There is $count1 files"

rand1=$[1000-$count1]

while [ $rand1 -lt 1000 ]
do
	rand1=$[ (( $RANDOM % ( $[ 9999 - 1000 ] + 1 ) ) + 1000) - $count1 ]
done

rand2=$[ ( $RANDOM % ( $[ 999 - 100 ] + 1 ) ) + 100 ]

for f in $FILES
do
	if [ "$f" ]
	then
		mobi2mobi --outfile "$f" --delexthtype 113 "$f"> /dev/null 2>&1
		mobi2mobi --outfile "$f" --delexthtype 501 "$f"> /dev/null 2>&1
		
		author=$(mobi2mobi "$f" | grep Author | cut -d- -f4)
		title=$(mobi2mobi "$f" | grep LONGTITLE | cut -c11-100)
		
		python asin_search.py "$title" "$author">asin.txt
		search1=`head -n 1 asin.txt`

		if [ "$search1" ]
		then
			mobi2mobi --outfile "$f" --exthtype 113 --exthdata $search1 "$f"> /dev/null 2>&1
			echo "Gave a real ASIN number to: $title. It's new number is $search1"
		else
			mobi2mobi --outfile "$f" --exthtype 113 --exthdata $asin1$rand2$rand1 "$f"> /dev/null 2>&1
			echo "Gave a fake ASIN number to: $title. It's new number is $asin1$rand2$rand1"
			rand1=$[$rand1+1]
		fi
		
		mobi2mobi --outfile "$f" --addexthtype 501 --exthdata "EBOK" "$f"> /dev/null 2>&1
		rm asin.txt
		continue
	fi
done

-Make sure the .sh file is executable (chmod +x amazon.sh)
-Copy the updated files to your kindle, android, iOS, etc.
-See if it worked!

If anyone gets some use out of this please let me know! My next project will be to get the covert art of the random ASIN numbers to work correctly on android, iOS, ect.

You guys are the best
