Hello,
I try to upgrade the firmware of SPA504G phones. They are currently in version 7.5.2. I've download spa50x-30x-7-5-7s.bin and spa50x-30x-7-5-7s.exe. This is an unlocked version of the phone as the admin password is empty?
1) Run spa50x-30x-7-5-7s.exe (no firewall, no UAC) : the process runs well but at the end of the last progress bar : upgrade failed : firmware upload incomplete
2) http://192.168.4.104/admin/upgrade?tftp://192.168.2.150/spa50x-30x-7-5-7s.bin : phone enter in upgrade mode, reboots but is still in 7.5.2
3) http://192.168.4.104/admin/upgrade?http://x.x.x.x/spa50x-30x-7-5-7s.bin : phone enter un upgrade mode, does not reboot and remains in 7.5.2
Any hope to upgrade these phones ?
Thanks in advance for help.
Best regards,
Guy
