- @Junak Verify the md5sum of the image you are trying to boot on the switch as in :
Switch# verify /md5 flash:/c1000-universalk9-mz.152-7.E4/c1000-universalk9-mz.152-7.E4.bin

Hello @Junak,
based on your output either the software image on the flash got corrupted or the flash itself has a problem.
The easiest way to restore functionality is to prepare an USB stick (up to 4GB with FAT16 works best) with the lastest firmware:
In case you get error messages when you try to copy the new firmware onto the flash, you might have to erase the flash.
Make sure to backup the config in that case before erasing the flash.
If you want to use the WebGUI you can also use the archive command to install the TAR-file, once the switch booted from USB.
HTH!

Be careful of CSCwo56969.
Bug ID might say this bug only affects 2960X-series family of switches but the firmware of the Catalyst 1000 series family of switches is "cut" from the same code and may have the same mistakes.

Yes, it is always good to keep an eye on potential bugs.
All 2960X switches got replaced already quite some time ago but I still run a few 2960CX and 3560CX switches on that code without any issues.
