8760 (3CRWE8760​75) Firmware img?

[RESRUDEBOY69]

Hi,

I have a 3Com Wireless 8760 Dual Radio 11a/b/g PoE Access Point, with firmware version 2.1.12, im trying to update it from these img files which the links were posted to me from HP.

https://h10145.www1.hp.com/downloads/SoftwareReleases.aspx?ProductNumber=JD016A&lang=en&cc=us&prodSeriesID=4177543

but they have an img extension, and the access point keeps saying invalid firmware image.

looking at the logs i have this:

Current free space=540672 , need space=2465772 , original file (vxWorks.bin) does not exis

im guessing its looking for a bin file, i tried to extract the img file with 7zip but that didnt work.

Any ideas?

Cheers

Found the solution: Upgrade via TFTP!

1) setup a TFTP Server
2) rename new application image to "3com-img.bin"
3) connect via SSH to AP (e.g. putty)
4) run this command at router's command prompt: copy tftp file
Select the type of download<1,2,3>: [1]:1
TFTP Source file name:3com-img.bin
TFTP Server IP:192.168.X.Y (IP of TFTP server)
I got:
Firmware version of system is v2.1.12 and Updating Run-Time code v02.02.33 NOW!
The AP will reboot automatically after firmware upgrade in 5 seconds!!
5) wait for reboot and enjoy

Cheers

TFTP works. some tips:

- disable firewall om workstation temporarily, ssh is commonly blocked

- use a simple free tftp server for windows: http://tftpd32.jounin.net/tftpd32_download.html

- place the 3com-img.bin file in same directory as tftp32.exe

- check if SSH access is enabled on AP (default it is off on my AP firmware). use port 22 (default)

- putty is found here: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html putty.exe will do the trick, topmost one in the list.

for the rest, do as described above
