First, get a correct python bundle.
I don't know where your update_python_0.3.N_install.bin comes from but the one from
https://www.mobileread.com/forums/sho...d.php?t=195474 is not a recovery bundle but a classic OTA2 bundle. It also doesn't contain any
temp directory.
Then:
Code:
kindletool extract update_python_0.3.N_install.bin temporary_folder
cd temporary_folder
del *.sig
del update-filelist.dat
kindletool create ota2 -d pwgbr * ../update_python_0.3.N_pwgbr_install.bin
