Reinstall boot image (IOS bin file) to Compact Flash memory of CISCO Router/Switch Through TFTP-Server (Do not use USB stick)
First of all download correct version of IOS image for your Router CISCO 1921 series.
Here I attached the link of official CISCO web site to download correct IOS image:
https://software.cisco.com/download/home/282977114/type/280805680/release/15.7.3M7
Then follow the steps as mention bellow (The way of successful installation without stress):
Stepp 1: Configure manually your PC/Laptop-TCP/IPv4 NIC interface
IP address: 192.168.10.3
Net mask: 255.255.255.0
Standard gateway: 192.168.10.2
Step 2: Installation of TFTP-Server
- Install on your PC TFTP-Server (Solar wind App recommended)
- Under TFTP-Server directory (C:\TFTP-Root\) save correct version of IOS boot image file for Router/Switch.
- Ex. C:\TFTP-Root\C2800nm-advipservicesk9-mz.124-4.T1.bin (in your case: c1900-universalk9-mz.SPA.157-3.M7.bin)
- Select File --> Configure (Configure the TFTP-Server) then press “Start” button.
Step 3: Connect cables (UTP and Console)
- Connect UTP cable one end to Router/Switch G0/0 or F0/0 Ethernet port (not any other ports)
- Connect UTP cable other-end to your PC/Laptop NIC Ethernet port.
- Connect console cable RJ-45 end to Router/Switch console port and other-end to Serial RS232 port or USB port.
Step 4: Install PuTTY to communicate with console port.
- Install PuTTY application and configure Serial connection as follows:
- Select serial radio button then change the speed 115200 and find correct com port COM1 or COM3 or COM5. (check with device manager)
- then Click “Open” button.
- Now power on the Router/Switch then it will prompt “Rommon 1 >” Router/Switcher command prompt.
Type following commands and press enter key each line. These all commands are having case sensitivity you cannot type small characters unless line 6.
Rommon 1 >
Rommon 1 > IP_ADDRESS=192.168.10.4
Rommon 2 > IP_SUBNET_MASK=255.255.255.0
Rommon 3 > DEFAULT_GATEWAY=192.168.10.2
Rommon 4 > TFTP_SERVER=192.168.10.3
Rommon 5 > TFTP_FILE=c2800nm-advipservicesk9-mz.124-4.T1.bin
Rommon 6 > tftpdnld -r
Press enter...Router/Switch will response as below:
IP_ADDRESS: 192.168.10.4
IP_SUBNET_MASK: 255.255.255.0
DEFAULT_GATEWAY: 192.168.10.2
TFTP_SERVER: 192.168.10.3
TFTP_FILE: c2800nm-advipservicesk9-mz.124-4.T1.bin
TFTP_VERBOSE: Progress
TFTP_RETRY_COUNT: 18
TFTP_TIMEOUT: 7200
TFTP_CHECKSUM: Yes
TFTP_MACADDR: 00:1b:d4:46:bf:c0
GE_PORT: Gigabit Ethernet 0
GE_SPEED_MODE: Auto
Invoke this command for disaster recovery only.
WARNING: all existing data in all partitions on flash: will be lost!
Do you wish to continue? y/n: [n]: y
Press “y” then you can notice TFTP-Server starts to response. If not, you have to check cable connectivity that have you properly connected the cables in correct ports or right IP configurations.

It is very important to know if your problem has solved using my solution that make easy for others to save their valuable time.
(Note: You will get some practical issues if your trying to boot up with USB stick using in usbflash0: or usbflash1: drives due to incompatibility of USB stick. Before you use the USB stick it should be compatible to CISCO routers and switches and also you should format it trough Router or Switch (not in your PC) on CLI prompt. You can type the CLI command in privilege mode Router# format usbflash0
Then you have to save the IOS boot image file on USB stick (c1900-universalk9-mz.SPA.157-3.M7.bin) using this command. Router# copy tftp://192.168.10.3 usbflash0:
