[asterisk-users] SPA3102 Firmware Upgrade via TFTP fails

[Georghy]

Hi everyone,
I'm trying to set up a VOIP mass deployment.
To do so, I want to generate a configuration xml fails.
I read somewhere that I had to use : http://<phone -or- device ip 
address>/admin/spacfg.xml
but it work with an upper firmware only.
My Software Version is 3.3.6(GW)
The last firmware versin is 5.1.10(GW)

Upgrade Enable: is set to yes on the linksys SPA3102 web interface

TFTP works because I tried to download and upload to the TFTP server and 
it worked fine

I tried to upgrade firmware via tftp using this command :
http://192.168.0.1/upgrade?tftp://192.168.0.2/spa.bin
but upgrade fails :s

syslog :
