I have a 2160 that seems to be stuck at 220.127.116.11. Normal config for the GS public firmware server isn’t working. Any hints on how to get it to pick up the newest firmware?
Following the directions for being on 1.0.4.x, even though this phone was on 1.0.5, worked.
Manually set the FW path to firmware.grandstream.com/gxp21xx/1_0_7_97, save, reboot.
Manually set the FW path to firmware.grandstream.com/gxp21xx/1_0_8_56, save, reboot.
Manually set the FW path to firmware.grandstream.com/gxp21xx/1_0_11_10, save, reboot. (It was not enough to set it to simply firmware.grandstream.com.)
Three steps later, and it’s on 18.104.22.168.
How did you know the FW path? I am having a similar problem on the GXP16xx series.
