WLC boot loader upgrade

Unanswered Question
May 26th, 2009

WLC2100, I'm trying to upgrade the bootloader, I downloaded the file -er.aes and did the upgrade without any error and after the reboot I still see the same old boot version. I tried the same procedure twice but still the same result. Can someone tell me what could be wrong.

I have this problem too.

Rob's right. 4.2.112.0 is the latest "true" bootloader (the others are just patches or improvements to the 4.2.112.0). So when you download the latest bootloader, 4.2.112.0 will still come up.

The ER image isn't technically the bootloader. It is an image that is loaded between the bootloader and the main image. The bootloader that is shown will update with the main image upgrade if needed.
