Not able to enter Rommon mode in a 3560

Hi guys,


I bought 2 3560 switches to practice my ccnp switch exam.
However when received those switches and booted them, they were set up with user login details which i don't know of course.
So I tried breaking the boot up to get in to rommon mode so i can make it skip the nvram. 
However it is not even letting me do that and proceeds on with with booting.
However i do get an error when loading the IOS, "Error loading "flash:c3560-ipbasek9-mz.122-46.SE/c3560-ipbasek9-mz.122-46.SE.bin"
please see below further:

password recovery should be here

 

Hold down the mode button located on the left side of the front panel, while you reconnect the power cable to the switch

it looks like someone updated IOS with 122-55 from 122-46 but it did not change boot command to boot from 55.
it is ok as long as switch loads 55 image.

did u follow password recovery procedures ? probably hold Mode button during initial boot

The switch is attempting to load a newer IOS version.
If you want to go into ROMMON you need to hold down the Mode button for about 20 seconds and after applying power.
