BBB won't boot with sdcard inserted after update_bootloader.sh

I ran the following from /opt/scripts/tools for no good reason other than curiosity:
update_bootloader.sh
update_kernel.sh
update_initrd.sh

Now my BBB goes to 4 solid blue lights if there is a microsd inserted during bootup. With no sd inserted, it boots up fine.

Serial log with sd inserted:

I can see it is obviously trying to boot off the sdcard and failing because there is no image on it. How can I fix this behavior an return it back no normal (so it won’t try to boot off the sdcard without S2 pressed) without reinstalling the system image?

reflash..

Reflash what? The whole image? As I said, I am trying to avoid doing that.
Is there really no easy way to fix whatever it is I broke?

The "easy" was is to reflash

To fix you'll have to first figure out what image you started with.
Flash that to a spare microSD, copy MLO/u-boot.img from it, replace
the existing MLO/u-boot.img on your current card.

When you do that:

sudo rm ./MLO
sudo cp /someotherlocation/MLO ./MLO
sync
sudo rm ./u-boot.img
sudo cp /someotherlocation/u-boot.img ./u-boot.img
sync

Ok thanks. That looks like something I can manage. I will give that a try.

Perfect! Replacing the MLO and u-boot files did the trick. It boots fine with the sdcard now. Thanks for the help.
Any idea why the updated versions of those files from the script caused this?
