Issue with 1252AG - Refusing to upgrade to newer IOS

[playstation3]

Hello everyone,

I am having issue with one of 1252AG when trying to upgrade from 124-25d-JA1 to 152-2.JA1 with web GUI (IE 11 and Chrome) and TFTP while mode. However, none of them would not upgrade. But odd, second 1252AG did upgraded to 152-2.JA1 and work flawness. First 1252AG still refusing but acceptable with 124-25d.JA1 or lower. I am trying to figuring what going on and still suggesting with this. How can I fix this?

Try to upgrade using one of these methods:

I have already try with TFTP via MODE nothing of these would work as I told above. I gotta try to check with console for tomorrow.

When you are doing the upgrade via TFTP & mode button, get the console connected & see what's happening. If upgrade fails, it should tells you at what point it is geting failed.

Here is a step by step process involve & try it again & post the console output if it fails

I am still having problem with this exactly on terminal. I have no idea what wrong with this 1252AG... Is there another way to fix this?

Unable to create temp dir "flash:/update

I know what this error message means.  Someone's already attempted to get this AP to join and download the firmware from the WLC but it was interrupted.

So when the OP tried to do it again, the "script" couldn't proceed because a subdirectory called "update" already exist.

Here's one of the fix:

Connect the AP to the power source (power brick or switch) but DO NOT CONNECT the switch to the WLC.  Log into the AP (username/password is "Cisco/Cisco").  In enable mode, issue the command "format flash:".  DO NOT REBOOT THE AP.  Once the format is complete, connect the switch to the WLC.

How can I do this? It seem it gave me error: Invalid Input detected as ^ marker however, I enabled the enable mode.

Never mind. I figured it out and now it formating.
