Well, you stopped a new kernel + firmware from installing by 'holding' raspberrypi-bootloader.
Then you installed a new kernel + firmware by using rpi-update...

rpi-update creates a backup of the contents of /boot (that's the FAT partition on your SD card) in /boot.bak.
Basically you need to copy the contents /boot.bak back to its origin.

AFAIK it should be possible to do this on a running system.
Make a backup of your SD card first. You could make an image with Win32DiskImager for example.
When you're logged in to your Pi you can copy the files with

Code: Select all

sudo cp -rv /boot.bak/* /boot/
Reboot and hope for the best.

And don't use rpi-update again
