I tried to use the GUI to upgrade my 1120 and mucked it up. The upgrade wiped out the flash but failed to upload the new .tar file. Now my AP is running (i haven't rebooted it) but I have no GUI. So, I have access to the CLI, I have a tftp server and a .tar file. Can I use the CLI and the tftp to recreate the flash file system with the .tar file? If not, how do I proceed from here? Seems like all the docs on the TAC are for upgrading 1130 and up APs to LWAPP but I believe that don't work with my 1120. Any ideas?
I guess you are talking about downloading a flash IOS from TFTP to AP1120. Right?
I just upgrade my 1120 one week ago. You can firstly check if there is ios folder in the flash and check the free size. If the old ios folder is gone, the free size should be enought for the new IOS. If you need to delete the old IOS, delete /re /f flash:xxxxxx (the ios folder name) to release the flash space. Then run archive download-sw ftp://xx.xx.xx.xx/xxxxxx.tar.
The download should start and take 3 mins. After that check flash if there is a new folder of the ios name. If yes, you should be able to run reload.
