You made two mistakes here. First and important is what juiceme already explained (booting up closed kernel).
And second one is that you flashed also the second time the rootfs image (-F org.img), hereby overwriting your untared new modules. You should have used "-a org.img" instead of "-F org.img".

But what I ask myself is why did it start at all? If you flashed the NAT kernel, it should need its modules at correct location!? Just like juiceme said:

Or?

Oops, the -R in first command is definitely wrong, just seen after writing post.
Just for the records. It should be enough to flash the kernel only in second command. And it is not needed to flash also eMMC (but of course you may do so). Just like:

Code:

flasher -F org.img  -f ; flasher -a org.img -k zImage-someopenimage --flash-only==kernel -f -R

Or it should/may also be possible with one flash command only (not tested/confirmed)l

Code:

flasher -F org.img -k zImage-someopenimage -f -R

Then do the developermode, modules and dep stuff and flash NAT kernel:

Code:

 flasher -a org.img -k zImage-NATimage --flash-only==kernel -f -R
