use "kindletool create". You also need to delete those update to kernel modules. I only change the file "611680021-1725970040.ffs". A list of files I bypassed:

/usr/lib/libwebkit-1.0.so.2.5.0
/lib/modules/2.6.26-rt-lab126/kernel/drivers/video/eink/legacy/eink_fb_shim.ko
/lib/modules/2.6.26-rt-lab126/kernel/drivers/usb/gadget/g_file_storage.ko
/etc/init.d/wpa_supplicant
/etc/fb.modes
kernel update

Here is the steps I did:

1) download the bin file from amazon. The one for wifi+3G.
2) "kindletool convert xxx.bin". concert it to .tgz/.tar.gz file.
3) unarchive the .tgz/tar.gz file to a sub-directory.
4) cd into the sub-directory, use any txt editor to open "611680021-1725970040.ffs". delete those lines related to the list of files above. Save the file. I also delete the kernel item in "update-Update_611680021-1725970040.dat".
5) use "kindletool create ota --device dxg * update_3.4.bin" to repack the files.
6) copy update_3.4.bin to kindle and update.
