hello @Xibachao1 To upgrade your Cisco 6300H AP from Mobility Express to Lightweight firmware via USB, download the lightweight firmware (for example: ap3g3-k9w8-tar.*) from Cisco’s support site, extract the .tar file, and copy it to a FAT32-formatted USB drive. Insert the USB into the AP and reboot—the AP should automatically detect and install the new firmware.

check this one: https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/107911-ios-upgrade.html looks like great info and ensure the firmware is compatible with your AP model before proceeding. hope it helps...

Hi @Enes Simnica ,

Following this matter, but i can not find any file .image in Cisco download.

It's always "Wrong image format for "source" command" or "Bad image type" showing in UBoot.

Here is all from file .tar from Cisco

hello G, If the .tar u downloaded only has info.ver and no .image, then my man, u are using the wrong file type. Thats why u-boot shows "Wrong image format" and "bad image type". U mmust get the Lightweight AP software image, not the Mobility express bundle.

So u need to go to Cisco Downloads for u AP model and look for the filename similar to ap1g6a-k9w8-tar.<version>.tar

then download it, and extract it with this tar -xvf ap1g6a-k9w8-tar.<version>.tar

which means that U SHOULD SEE .IMAGE FILE, HTML FILES AND MANIFEST FILES. IF U ONLY SEE INFO.VER, IT MEANS THAT IS NOT THE CORRECT IMAGE FOR CONVERSION...
