How to upgrade the AP version through Uboot

Uboot-based upgrade is used when an AP cannot start and enter the command line mode. Uboot-based upgrade is complex and requires you to strictly follow the procedures. Therefore, you are not advised to use this method to upgrade the AP version.

Perform the following operations to upgrade the AP version through Uboot:

1. Connect the serial ports of the PC and AC with a serial cable and use the HyperTerminal to access the CLI.

2. Obtain the firmware file u-boot.bin and the software package FatAP6X10XN_V200R005C10.bin from Huawei official website, and save them to a TFTP directory.

3. Run the reboot command to restart the AP. After the following information is displayed, press F within three seconds to enter the Uboot CLI.
