hi

Hi Aslam,
The best way is to use a tftp server app on a pc with the IOS you wish to install and connect a cross-over cable between switch and pc.
on pc:
Static ip address - lets say 172.16.1.10 mask 255.255.255.0
on the switch:
rommon:
set
IP_ADDRESS=172.16.1.4
IP_SUBNET_MASK=255.255.255.0
DEFAULT_GATEWAY=172.16.1.4
TFTP_SERVER=172.16.1.10
TFTP_FILE=c3560-advipservicesk9-mz.122-46.SE.bin
TFTP_VERBOSE=2
TFTP_RETRY_COUNT=20
sync
tftpdnld

Hi,
I am not sure if you can use tftpdnld on switches
Follow these steps, these will help u to ugrade successfully.
When the switch is on ROMMON mode, issue these commands,
load_helper
flash_init --- to initialize the flash memory
dir flash: --- to see if you already have an IOS in the flash
If you have IOS in the flash then use below command to boot up using that IOS.
boot flash:IOS-name.bin
If you don't have IOS in the flash then use below command to load IOS to flash using xmodem method.
copy xmodem: flash:IOS-name.bin
After its done, boot with new IOS.
boot flash:IOS-name.bin
