Whatever the size of your flash may be. The default is 1MiB.

Is your CONFIG_CBFS_SIZE ok for 1MiB. If you changed back the flash size
then it might not have followed. An easy way is to 'rm -rf .config' and
run make menuconfig again or simply adapt the size.

Not sure what you are asking here...

Not possible unless the rom is compiled for a virtual target like qemu.
On real hardware you should make a backup of the original firmware.
