The file fails to load or boot on your router.
These issues may prevent your router from functioning properly or cause unexpected errors. To troubleshoot these issues, you can use some of these methods:
Use the verify command to check the integrity of the file. This command will calculate and compare the checksum of the file and report any discrepancies.
Use the show version command to check the current version of Cisco IOS software running on your router. This command will also display the system image file name and location, as well as the memory requirements and licensing terms of the file.
Use the show flash command to check the contents and status of your flash memory. This command will also display the file size and checksum of each file in flash memory.

How to Choose the Right Cisco C3600 IOS Image .bin File for Your Router?
There are many different Cisco C3600 IOS image .bin files available for Cisco 3600 series routers. Each file has a different name that indicates the router model, the feature set, and the version of Cisco IOS software. For example, a file named c3600-ip-mz.122-2.XT3.bin means that it is for a Cisco 3600 series router with the IP feature set and Cisco IOS version 12.2 (2) XT3.
To choose the right Cisco C3600 IOS image .bin file for your router, you need to consider these factors:
The router model that you have. You need to use a system image file that is compatible with your router model. For example, if you have a Cisco 3660 router, you need to use a file that starts with c3660.
The features that you need. You need to use a system image file that supports the features and capabilities that you need for your network. For example, if you need voice over IP (VoIP) features, you need to use a file that has -v or -ivs in its name.
The memory requirements of the file. You need to use a system image file that fits in your router's flash memory and RAM. For example, if you have 32 MB of flash memory and 128 MB of RAM, you need to use a file that is less than 32 MB in size and requires less than 128 MB of RAM.
The licensing terms of the file. You need to use a system image file that is authorized for your router and your service contract. For example, if you have a feature license for Cisco Survivable Remote Site Telephony (SRS Telephony), you need to use a file that has -srs in its name.
You can find more information about the different Cisco C3600 IOS image .bin files on the Cisco website or on the Cisco Software Download Center. You can also use the show version command on your router to see the current system image file name and location, as well as the memory requirements and licensing terms of the file.
How to Backup and Restore Your Cisco C3600 IOS Image .bin File?
It is important to backup your Cisco C3600 IOS image .bin file before you download and install a new one on your router. This way, you can restore your original system image file if something goes wrong with the new one or if you want to revert to the previous version.
To backup your Cisco C3600 IOS image .bin file, you need to copy it from your router's flash memory to another device, such as a TFTP server or a USB drive. You can use one of these commands to do this:
If you are using FTP (File Transfer Protocol), use this command:
Router# copy flash: ftp:
If you are using TFTP (Trivial File Transfer Protocol), use this command:
Router# copy flash: tftp:
If you are using HTTP (Hypertext Transfer Protocol), use this command:
Router# copy flash: http:
You need to specify
the source
and destination
of
the
file transfer.
For example,
if
your
system
image
file
is named c3600-js-mz.122-2.XT3.bin,
and
you want to copy it
to
a TFTP server with an IP address of 10.10.10.10,
you can use this command:
Router# copy flash: tftp:
Source filename [c3600-js-mz.122-2.XT3.bin]?
Address or name of remote host [10.10.10.10]?
Destination filename [c3600-js-mz.122-2.XT3.bin]?
Accessing tftp://10.10.10.10/c3600-js-mz.122-2.XT3.bin...
Writing c3600-js-mz.122-2.XT3.bin...!
[OK - 12345678 bytes]
12345678 bytes copied in 123 seconds (1234 bytes/sec)
The command will prompt you for some information and then start copying
the
file from
your
router's flash memory
to
the TFTP server.
You will see some progress indicators as
the
file is being transferred.
Once
the
file is copied,
you will see a confirmation message with some details about
the
file size and transfer time.
To restore your Cisco C3600 IOS image .bin file, you need to copy it from another device back to your router's flash memory. You can use one of these commands to do this:
If you are using FTP (File Transfer Protocol), use this command:
Router# copy ftp: flash:
If you are using TFTP (Trivial File Transfer Protocol), use this command:
Router# copy tftp: flash:
If you are using HTTP (Hypertext Transfer Protocol), use this command:
Router# copy http: flash:
You need to specify
the source
and destination
of
the
file transfer.
For example,
if
your
system
image
file
is named c3600-js-mz.122-2.XT3.bin,
and
you want to copy it from
a TFTP server with an IP address of 10.10.10.10,
you can use this command:
Router# copy tftp: flash:
Address or name of remote host [10.10.10.10]?
Source filename [c3600-js-mz.122-2.XT3.bin]?
Destination filename [c3600-js-mz.122-2.XT3.bin]?
Accessing tftp://10.10.10.10/c3600-js-mz.122-2.XT3.bin...
Loading c3600-js-mz.122-2.XT3.bin from 10.10.10.10 (via FastEthernet0/0): !
[OK - 12345678 bytes]
12345678 bytes copied in 123 seconds (1234 bytes/sec)
The command will prompt you for some information and then start copying
the
file from
the TFTP server
to
your
router's flash memory.
You will see some progress indicators as
the
file is being transferred.
Once
the
file is copied,
