Help me in upgrading IOS on 1841. I can see .bin file in flash but when I type del that file I get error file not found.
The additional information is useful. It does show that there is a bit less than 8 MB available in flash. The part that I find most interesting is the file named "y" which appears to have been created today and has over 14 MB of space. Can you tell us what that file is?
To load the new image you will need to delete something to free up enough space so that the new image will fit. From my perspective the easy choice would be to delete the file named y. If you do not want to delete this one, then we need to identify enough of the other files in flash so that you can delete them and get enough space for the new image.
