Hi guys! My compliments to the support team!
I had a problem with the GXP2100. First, a message was displayed on the display to update the firmware. Through the WEB browser on the control panel is not connected. I connected through telnet. I specified the upgrade option via FTP. Saves the changes. I launched a TFTP server on my computer with a new firmware. On the phone, the reboot process was started by the REBOOT command.
After reboot, the phone stops at the stage:
Loading user data… Done
And now I can not connect to the phone via telnet anymore.
Help please solve this problem.
